1+# stylish-haskell configuration file
2+# ==================================
3+
4+# The stylish-haskell tool is mainly configured by specifying steps. These steps
5+# are a list, so they have an order, and one specific step may appear more than
6+# once (if needed). Each file is processed by these steps in the given order.
7+steps:
8+ # Convert some ASCII sequences to their Unicode equivalents. This is disabled
9+ # by default.
10+ # - unicode_syntax:
11+ # # In order to make this work, we also need to insert the UnicodeSyntax
12+ # # language pragma. If this flag is set to true, we insert it when it's
13+ # # not already present. You may want to disable it if you configure
14+ # # language extensions using some other method than pragmas. Default:
15+ # # true.
16+ # add_language_pragma: true
17+
18+ # Import cleanup
19+ - imports:
20+ # There are different ways we can align names and lists.
21+ #
22+ # - global: Align the import names and import list throughout the entire
23+ # file.
24+ #
25+ # - file: Like global, but don't add padding when there are no qualified
26+ # imports in the file.
27+ #
28+ # - group: Only align the imports per group (a group is formed by adjacent
29+ # import lines).
30+ #
31+ # - none: Do not perform any alignment.
32+ #
33+ # Default: global.
34+ align: none
35+
36+ # Folowing options affect only import list alignment.
37+ #
38+ # List align has following options:
39+ #
40+ # - after_alias: Import list is aligned with end of import including
41+ # 'as' and 'hiding' keywords.
42+ #
43+ # > import qualified Data.List as List (concat, foldl, foldr, head,
44+ # > init, last, length)
45+ #
46+ # - with_alias: Import list is aligned with start of alias or hiding.
47+ #
48+ # > import qualified Data.List as List (concat, foldl, foldr, head,
49+ # > init, last, length)
50+ #
51+ # - new_line: Import list starts always on new line.
52+ #
53+ # > import qualified Data.List as List
54+ # > (concat, foldl, foldr, head, init, last, length)
55+ #
56+ # Default: after_alias
57+ list_align: after_alias
58+
59+ # Long list align style takes effect when import is too long. This is
60+ # determined by 'columns' setting.
61+ #
62+ # - inline: This option will put as much specs on same line as possible.
63+ #
64+ # - new_line: Import list will start on new line.
65+ #
66+ # - new_line_multiline: Import list will start on new line when it's
67+ # short enough to fit to single line. Otherwise it'll be multiline.
68+ #
69+ # - multiline: One line per import list entry.
70+ # Type with contructor list acts like single import.
71+ #
72+ # > import qualified Data.Map as M
73+ # > ( empty
74+ # > , singleton
75+ # > , ...
76+ # > , delete
77+ # > )
78+ #
79+ # Default: inline
80+ long_list_align: inline
81+
82+ # List padding determines indentation of import list on lines after import.
83+ # This option affects 'list_align' and 'long_list_align'.
84+ list_padding: 4
85+
86+ # Separate lists option affects formating of import list for type
87+ # or class. The only difference is single space between type and list
88+ # of constructors, selectors and class functions.
89+ #
90+ # - true: There is single space between Foldable type and list of it's
91+ # functions.
92+ #
93+ # > import Data.Foldable (Foldable (fold, foldl, foldMap))
94+ #
95+ # - false: There is no space between Foldable type and list of it's
96+ # functions.

99+ #
100+ # Default: true
101+ separate_lists: false
102+
103+ # Language pragmas
104+ - language_pragmas:
105+ # We can generate different styles of language pragma lists.
106+ #
107+ # - vertical: Vertical-spaced language pragmas, one per line.
108+ #
109+ # - compact: A more compact style.
110+ #
111+ # - compact_line: Similar to compact, but wrap each line with
112+ # `{-#LANGUAGE #-}'.
113+ #
114+ # Default: vertical.
115+ style: compact
116+
117+ # Align affects alignment of closing pragma brackets.
118+ #
119+ # - true: Brackets are aligned in same collumn.
120+ #

140+ # Remove trailing whitespace
141+ - trailing_whitespace: {}
142+
143+# A common setting is the number of columns (parts of) code will be wrapped
144+# to. Different steps take this into account. Default: 80.
145+columns: 80
146+
147+# Sometimes, language extensions are specified in a cabal file or from the
148+# command line instead of using language pragmas in the file. stylish-haskell
149+# needs to be aware of these, so it can parse the file correctly.
150+#
151+# No language extensions are enabled by default.

1+# New since last release
2++ Updated to work with GHC 8.8 and cabal 3.0
3+
4+# New in 1.3.2
5++ Documentation added to proof section
6+
7+## Library updates
8++ `openFile` opens the file in binary mode on Windows.
9++ Added library functions `clockTime` and `fRemove`
10+
11+## Tool updates
12++ Modules no longer require building if imports have changed but all
13+ interfaces (i.e. types for names declared `export` and definitions of names
14+ declared `public export`) are unchanged.
15++ The result of calling `:doc` now details the accessbility of items as well as their totality.
16+
17+## Miscellaneous updates
18++ Compiler flag `--optimise-nat-like-types` enables compilation
19+ of `Nat`-like type families to big integers. A type family
20+ is `Nat`-like if, after erasure, it has two constructors,
21+ one nullary, the other one with exactly one recursive field.
22+
23+# New in 1.3.1
24+
25+## Tool updates
26++ Fixes for building with GHC 8.6
27++ Fix for megaparsec update
28++ Some fixes for memory allocation issues in the C back end
29+
30+# New in 1.3.0
31+
32+## Language updates
33++ Old 'induction' tactics and eliminator generation functionality ('%elim', '%case', 'elim_for') is no longer supported.
34+ Please, rely on the ones provided by Pruviloj and elaborator reflection instead.
35+
36+## Library updates
37+
38++ Changed rndInt in Effect.Random so that it does not alternate between odd
39+ and even.
40++ Additions to `contrib`:
41+ * `Data.SortedBag`: Bag (or Multiset) implemention based on `Data.SortedMap`.
42+ * `Data.PosNat`: A `Nat` paired with a proof that it is positive.
43+ * `Data.Chain`: A function with an arbitrary number of arguments, plus
44+ combinators for working with them.
45+
46+## Tool updates
47++ Added a switch `--allow-capitalized-pattern-variables` to optionally allow capitalized pattern variables after they were prohibited in 1.2.0.
48++ REPL now prints an error message if program compiled by `:exec` terminates
49+ abnormally.
50++ Idris now builds with GHC 8.4.
51++ In the C backend, the representation of Idris values at runtime has been reworked.
52+
53+# New in 1.2.0
54+
55+## Language updates
56+
57++ In `@`-patterns such as `x@p`, `x` is now in scope on the right-hand side
58+ of any definitions in `where` clauses, provided the left-hand side of the
59+ definition does not shadow it.
60++ The `LinearTypes` language extension has been revised. It implements the
61+ rules from Bob Atkey's draft "The Syntax and Semantics of Quantitative
62+ Type Theory" and now works with holes and case expressions.
63++ Backticked operators can appear in sections, e.g. ``(`LTE` 42)`` or
64+ ``(1 `plus`)``.
65++ Backticked operators can have their precendence and associativity set like
66+ other operators, e.g. ``infixr 8 `cons` ``. Backticked operators with
67+ undeclared fixity are treated as non-associative with precedence lower
68+ than all declared operators.
69++ Allow non-injective implementations if explicitly named, e.g.,
70+ ```idris
71+ LTB : Nat -> Type
72+ LTB b = DPair Nat (\ n => LT n b)
73+
74+ implementation [uninhabltb] Uninhabited (LTB Z) where
75+ uninhabited (MkDPair n prf) = absurd prf
76+ ```
77+ It is possible to use `using implementation uninhabltb` to add the
78+ implementation to the automated resolution, but if it fails to find the
79+ instance due to non-injectivity, one must pass it explicitly to target
80+ function, i.e. `absurd @{uninhabltb}`.
81++ Verbatim strings now support trailing quote characters. All quote characters
82+ until the final three are considered part of the string. Now a string such as
83+ `""""hello""""` will parse, and is equivalent to `"\"hello\""`.
84++ C FFI now supports pasting in any expression by prefixing it with '#', e.g.
85+ ```idris
86+ intMax : IO Int
87+ intMax = foreign FFI_C "#INT_MAX" (IO Int)
88+ ```
89++ The deprecated keywords `%assert_total`, `abstract`, and `[static]` have
90+ been removed as well as the use of "public" instead of "public export" to
91+ expose a symbol.
92++ The syntax for pattern-match alternatives now works for `let` statements in
93+ `do` blocks in addition to `let` expressions and `<-` statements, e.g.
94+ ```idris
95+ do …
96+ let Just x = expr | Nothing => empty
97+ …
98+ ```
99+ This means that a `with`-application (using `|`) cannot be used in that
100+ position anymore.
101+
102+## Library Updates
103+
104++ Removed `oldeffects` library from `libs` folder, use `effects` or `Control.ST` instead.
105++ Added `Text.Literate`, a module for working with literate source files.
106++ Added `Data.IORef`, for working with mutable references in `IO` and `JS_IO`.
107++ Added `discriminate` and `construct` tactics to Pruviloj.
108++ Added `IsSucc` type to `Prelude`, which proves that a `Nat` is a successor.
109++ Added `Data.IOArray`, containing primitives for mutable arrays.
110++ Added `Language.JSON`, for total serialization/deserialization of JSON data.
111++ Reworked operator fixity for many operators.
112+ * Changed `&&` and `||` to be right-associative. Increased precedence of `&&`
113+ to be higher than that of `||`.
114+ * Removed associativity from Boolean comparison operators `==`, `/=`, `<`, `<=`,
115+ `>`, and `>=`. Increased precedence of `/=` and `==` to match the others.
116+ * Made `<|>`, `<$>`, and `.` right-associative.
117+ * Swapped precedence of `<|>` and `<*>` (and its related operators, `<*` and
118+ `*>`). Now `<|>` has a lower precedence.
119+ * Lowered the precedence of `>>=` to be below that of `<|>`.
120++ Added some useful string manipulation functions to `Data.String.Extra`.
121++ Added `Control.Delayed`, a module for conditionally making a type `Inf` or `Lazy`.
122++ Added `Data.Fuel`, which implements the `Fuel` data type and the partial `forever` function.
123++ Added `Data.Bool.Extra`, a module with properties of boolean operations.
124++ Moved core of `Text.Lexer` to `Text.Lexer.Core`. Added several new combinators
125+ and lexers to `Text.Lexer`.
126++ Moved core of `Text.Parser` to `Text.Parser.Core`. Added several new combinators
127+ to `Text.Parser`. Made the following changes.
128+ * Flipped argument order of `parse`.
129+ * Renamed `optional` to `option` and flip argument order.
130+ * Renamed `maybe` to `optional`.
131+ * Generalised many combinators to use an unknown `commit` flag where possible.
132++ `Prelude.Doubles.atan2` is now implemented as a primitive instead of
133+ being coded in Idris.
134++ Added `Test.Unit` to `contrib` for simple unit testing.
135++ Removed several deprecated items from the libraries shipped with Idris.
136++ Moved `abs` from the `Neg` interface into its own `Abs` interface. `Nat`
137+ implements `Abs` with `abs = id`.
138++ Added `Control.ST.File`, an ST based implementation of the same behaviour
139+ implemented by `Effect.File` in the effects package.
140+
141+## Tool Updates
142+
143++ Private functions are no longer visible in the REPL except for modules
144+ that are explicitly loaded.
145++ The --interface option now creates CommonJS modules on the node backend.
146++ The C backend now pass arguments to the C compiler in the same order
147+ as they were given in the source files.
148++ Backslash, braces and percent symbols are now correctly pretty printed
149+ in LaTeX.
150++ Errors and warnings now consistently have the following format:
151+ ```idris
152+ reg068.idr:1:6-8:
153+ |
154+ 1 | data nat : Type where --error
155+ | ~~~
156+ Main.nat has a name which may be implicitly bound.
157+ This is likely to lead to problems!
158+ ```
159+ The code is highlighted when highlighting information is available. How
160+ much highlighting information is available depends on where the error
161+ occurred.
162++ The parser provider has been switched from Trifecta to Megaparsec. This
163+ could possibly cause some subtle deviations in parsing from previous
164+ versions of Idris.
165++ Many more errors now report beginning *and* ending position (which may be
166+ on different lines), instead of just a single point. The format is
167+ `Foo.idr:9:7-15:` if ending column is on the same line or
168+ `Foo.idr:9:7-10:15:` if the ending column is on a different line.
169++ Error messages were changed so that the last column is inclusive, e.g.
170+ `Foo.idr:9:7-15:` includes column 15. Previously the error would have read
171+ `Foo.idr:9:7-16:`.
172+
173+## Packaging Updates
174+
175++ Package names now only accept a restrictive charset of letters, numbers and the `-_` characters.
176+ Package names are also case insensitive.
177++ When building makefiles for the FFI, the environment variables
178+ `IDRIS_INCLUDES` and `IDRIS_LDFLAGS` are now set with the correct C
179+ flags.
180+
181+# New in 1.1.1
182+
183++ Erasure analysis is now faster thanks to a bit smarter constraint solving.
184++ Fixed installation issue
185++ Fixed a potential segfault when concatenating strings
186+
187+# New in 1.1.0
188+
189+## Library Updates
190+
191++ Added `Text.PrettyPrint.WL` an implementation of the Wadler-Leijen
192+ Pretty-Print algorithm. Useful for those wishing to pretty print
193+ things.
194++ Added `Text.Lexer` and `Text.Parser` to `contrib`. These are small libraries
195+ for implementing total lexical analysers and parsers.
196++ New instances:
197+ + Added `Catchable` for `ReaderT`, `WriterT`, and `RWST`.
198+ + Added `MonadTrans` for `RWST`.
199++ Added utility functions to `Data.SortedMap` and `Data.SortedSet` (`contrib`),
200+ most notably `merge`, merging two maps by their `Semigroup` op (`<+>`)
201++ `Prelude.WellFounded` now contains an interface `Sized a` that defines a size
202+ mapping from `a` to `Nat`. For example, there is an implementation for lists,
203+ where `size = length`.
204+
205+ The function `sizeAccessible` then proves well-foundedness of the relation
206+ `Smaller x y = LT (size x) (size y)`, which allows us to use strong
207+ induction conveniently with any type that implements `Sized`.
208+
209+ In practice, this allows us to write functions that recurse not only on
210+ direct subterms of their arguments but on any value
211+ with a (strictly) smaller `size`.
212+
213+ A good example of this idiom at work is `Data.List.Views.splitRec` from `base`.
214++ Added utility lemma `decEqSelfIsYes : decEq x x = Yes Refl` to
215+ `Decidable.Equality`. This is primarily useful for proving properties of
216+ functions defined with the help of `decEq`.
217+
218+## Tool Updates
219+
220++ New JavaScript code generator that uses an higher level intermediate
221+ representation.
222+
223++ Various optimizations of the new JavaScript code generator.
224+
225++ Names are now annotated with their representations over the IDE
226+ protocol, which allows IDEs to provide commands that work on special
227+ names that don't have syntax, such as case block names.
228+
229+

236+## Library Updates
237+
238++ Added `Data.Buffer` to `base`. This allows basic manipulation of mutable
239+ buffers of `Bits8`, including reading from and writing to files.
240+
241+## Tool Updates
242+
243++ Idris now checks the list of packages specified at the command line
244+ against those installed. If there is a mismatch Idris will complain.

1+Extending Idris using Elaborator Reflection
2+===========================================
3+
4+Idris provides a mechanism to modify the language without having to recompile Idris itself. We can think of this in terms of metaprogramming or domain specific languages or just building in new capabilities.
5+
6+In order to extend the language we need to know something about how Idris is compiled. This page explains only what is needed to customise the elaboration. For more information about the compiler's implementation see `Edwin Brady's 2013 paper`_ and for customising the elaboration process see `Elaborator reflection: extending Idris in Idris`_ and `David Christiansen's PhD thesis`_.
7+
8+Compilation of Idris proceeds through a number of stages.
9+
10+- First, Idris is desugared by inserting placeholders for terms to be guessed by the compiler and replacing certain syntactic forms, such as do-notation, with the functions that implement them.
11+- Then, this desugared Idris is translated into a much simpler core language, called TT. This translation process is called elaboration.
12+- Finally, TT is type checked a second time to rule out errors, and then compiled into the target language.
13+
14+.. image:: ../image/idrisTopLevel.png
15+ :width: 484px
16+ :height: 147px
17+ :alt: diagram illustrating these stages of Idris compilation
18+
19+TT is a core language which is syntactically very simple. This makes it easy for computers to process but very verbose and hard for humans to read. The Idris elaborator is written in Haskell using an elaboration library that was inspired by the tactics in interactive proof assistants such as Coq.
20+
21+.. list-table::
22+
23+ * - There are some similarities with a proof assistant but in Idris the elaborator is an interpreter of Idris source in the elaboration monad, where each syntactic construct of Idris is interpreted as a sequence of tactics.
24+ - .. image:: ../image/compareToProofAssist.png
25+ :width: 206px
26+ :height: 112px
27+ :alt: diagram comparing elaboration with proof assistant
28+
29+The primitives in the elaboration library are not just useful for the implementors of Idris itself. They can also be used by authors of extensions to the compiler, using a mechanism known as elaborator reflection.
30+During elaboration TT (Raw) structure contains:
31+
32+- holes - placeholders for terms that have not yet been filled in.
33+- guesses - similar to let bindings, except with no reduction rule, so that elaboration programs can control the precise shape of terms that are under construction.
34+
35+For more information about holes and guesses see `Dependently Typed Functional Programs and their Proofs by McBride 1999`_.
36+
37+The following diagram is intended to illustrate a high level view of the tactics and how this eventually results in the TT language being generated. It is not necessary to understand the details at this stage. The intention is to help build up some intuition so that, when we get into the details, we can recognise how this fits into the big picture.

However, when learning about tactics, they may appear arbitrary without knowing some theory. For more information about this see `Edwin Brady's 2013 paper`_.

18+
19+ * - At the beginning of executing the elaboration script, the initial state consists of a single hole of type Nat -> Nat.
20+
21+ As a first approximation, the state consists of a term with holes in it, an indicator of which hole is focused, a queue of the next holes to focus on, and miscellaneous information like a source of fresh names. The intro tactic modifies this state, replacing the focused hole with a lambda and focusing on the lambda's body.

1+Generating Datatypes and Functions at Compile Time
2+==================================================
3+
4+Program elements, such as datatypes and functions can be constructed at compile-time in the Elab monad.
5+This can allow proofs to be generated for user defined types or it could allow types to be automatically generated to support user defined types.
6+An example is the code, from `Elaborator reflection: extending Idris in Idris`_, that automatically generates accessibility predicates using the Bove-Capretta method.
7+
8+Generating Datatypes
9+--------------------
10+
11+There are two main 'tactics' associated with generating datatypes:
12+
13+- declareDatatype
14+- defineDatatype
15+
16+Which declare and define the datatype as the names suggest.
17+
18+.. list-table::
19+
20+ * - These 'tactics' and the data structures associated with them are listed in the tables later on this page, for now, here is a summary:
21+ - .. image:: ../image/generateDatatype.png
22+ :width: 332px
23+ :height: 246px
24+ :alt: diagram illustrating data structures associated with declareDatatype defineDatatype.
25+
26+.. list-table::
27+
28+ * - As a first example, the following boolean-like type can be constructed. When the compiler has run it will be available to us as if we had compiled it in the usual way:
29+ - .. code-block:: idris
30+
31+ λΠ> :printdef Two
32+ data Two : Type where
33+ F : Two
34+ T : Two
35+
36+This was generated by the following code:
37+
38+.. code-block:: idris
39+
40+ module TwoDef
41+ %language ElabReflection
42+
43+ addTwo : Elab ()
44+ addTwo = do let twoname : TTName = `{{TwoDef.Two}}
45+ let F2 = `{{TwoDef.F}}
46+ let T2 = `{{TwoDef.T}}
47+ declareDatatype $ Declare twoname [] `(Type)
48+ defineDatatype $ DefineDatatype twoname [
49+ Constructor `{{F}} [] (Var `{{TwoDef.Two}}),
50+ Constructor `{{T}} [] (Var `{{TwoDef.Two}})
51+ ]
52+
53+ %runElab addTwo
54+
55+.. list-table::
56+
57+ * - The constructors T and F can be called as would be expected:
58+ - .. code-block:: idris
59+
60+ λΠ> F
61+ F : Two
62+ λΠ> T
63+ T : Two
64+
65+Generating Functions
66+--------------------
67+
68+There are two main 'tactics' associated with generating functions:
69+
70+- declareType
71+- defineFunction
72+
73+Which declare and define the function as the names suggest.
74+
75+.. list-table::
76+
77+ * - These 'tactics' and the data structures associated with them are listed in the tables later on this page, for now, here is a summary:
78+ - .. image:: ../image/generateFunction.png
79+ :width: 332px
80+ :height: 246px
81+ :alt: diagram illustrating data structures associated with function declare and define.
82+
83+Note: The left hand side (lhs) and right hand side (rhs) of FunClause typically is of type 'Raw'.
84+
85+.. list-table::
86+
87+ * - Bound pattern variables are represented by 'PVar' binders:
88+ This diagram shows an example of a possible Raw structure that might be used in a function definition.
89+ - .. image:: ../image/generateFunction2.png
90+ :width: 264px
91+ :height: 239px
92+ :alt: diagram illustrating data structures associated with functions.
93+
94+.. list-table::
95+
96+ * - Some function definitions can now be added to the above datatype. This is what they will look like:
97+ - .. code-block:: idris
98+
99+ λΠ> :printdef perm1
100+ perm1 : Two -> Two
101+ perm1 F = F
102+ perm1 T = T
103+ λΠ> :printdef perm2
104+ perm2 : Two -> Two
105+ perm1 F = T
106+ perm1 T = F
107+
108+This was generated with the following code:
109+
110+.. code-block:: idris
111+
112+ let perm1 = `{{TwoDef.perm1}}
113+ declareType (Declare perm1 [MkFunArg `{{code}} (Var twoname) Explicit NotErased] (Var twoname))
114+ defineFunction $ DefineFun perm1 [
115+ MkFunClause (RApp (Var perm1) (Var `{{TwoDef.F}})) (Var F2),
116+ MkFunClause (RApp (Var perm1) (Var `{{TwoDef.T}})) (Var T2)
117+ ]
118+
119+ let perm2 = `{{TwoDef.perm2}}
120+ declareType (Declare perm2 [MkFunArg `{{code}} (Var twoname) Explicit NotErased] (Var twoname))
121+ defineFunction $ DefineFun perm2 [
122+ MkFunClause (RApp (Var perm1) (Var `{{TwoDef.F}})) (Var T2),
123+ MkFunClause (RApp (Var perm1) (Var `{{TwoDef.T}})) (Var F2)
124+ ]
125+
126+.. list-table::
127+
128+ * - This is what happens when we call the functions:
129+ - .. code-block:: idris
130+
131+ λΠ> perm1 F
132+ F : Two
133+ λΠ> perm1 T
134+ T : Two
135+ λΠ> perm2 F
136+ T : Two
137+ λΠ> perm2 T
138+ F : Two
139+
140+So far these datatypes and functions could have been written, statically, in the usual way. However, it is possible to imagine situations where we may need a lot of functions to be generated automatically at compile time. For example, if we extend this Boolean datatype to a datatype with more simple constructors (a finite set), we could generate a function for every possible permutation of that datatype back to itself.
141+
142+A Different Example which has Type Parameters
143+---------------------------------------------
144+
145+.. list-table::
146+
147+ * - Here is an example of a datatype with type parameters:
148+ - .. code-block:: idris
149+
150+ data N : Nat -> Type where
151+ MkN : N x
152+ MkN' : (x : Nat) -> N (S x)
153+
154+This was produced by the following code:
155+
156+.. code-block:: idris
157+
158+ module DataDef
159+ %language ElabReflection
160+
161+ addData : Elab ()
162+ addData = do
163+ let dataname : TTName = `{{DataDef.N}}
164+ declareDatatype $ Declare dataname [MkFunArg `{{n}} `(Nat) Explicit NotErased] `(Type)
165+ defineDatatype $ DefineDatatype dataname [
166+ Constructor `{{MkN}} [MkFunArg `{{x}} `(Nat) Implicit NotErased]
167+ (RApp (Var dataname) (Var `{{x}})),
168+ Constructor `{{MkN'}} [MkFunArg `{{x}} `(Nat) Explicit NotErased]
169+ (RApp (Var dataname) (RApp (Var `{S}) (Var `{{x}})))
170+ ]
171+
172+ %runElab addData
173+
174+So this declares and defines the following data structure 'N' with a constructor 'MkN' which can have an implicit or an explicit Nat argument. Which can be used like this:
175+
176+.. code-block:: idris
177+
178+ λΠ> :t N
179+ N : Nat -> Type
180+ λΠ> N 2
181+ N 2 : Type
182+ λΠ> N 0
183+ N 0 : Type
184+ λΠ> :t MkN
185+ MkN : N x
186+
187+Table of 'tactics' for Generating Data and Functions
188+----------------------------------------------------

190+These are the functions that we can use to create data and functions in the Elab monad:

243+
244+Table of Datatypes Associated with Generating Data and Functions

247+The above functions use the following data/records:

1+Elaborator Reflection - Holes
2+=============================
3+
4+The process of doing proofs and elaborator reflection tends to involve stating with a desired conclusion and working back to known premises. This often needs intermediate sub-goals which may only be partially solved, these are encoded using 'holes' and 'guesses'.
5+
6+* A hole is a term (an expression - a chunk of code) which is yet to be determined. We do have information about its type (this process tends to be type driven).
7+* A guess is like a hole that is not yet bound.
8+
9+The theory around this was developed in `Dependently Typed Functional Programs and their Proofs by McBride 1999`_.
10+
11+Notation for Holes and Guesses
12+------------------------------
13+
14+There is a notation used in the McBride 1999 thesis which is adapted for the TT language. When working on elaborator reflection it is useful to know this notation, for instance when reading the output of the 'debug' tactic.
15+
16+* A focused hole is notated like this ?x:t . t
17+* A guess is notated like this ?x ≈ t:t . t
18+
19+The following example shows how this is used:
20+
21+Simple Example
22+--------------
23+
24+Start with a code file that just contains:
25+
26+.. code-block:: idris
27+
28+ %language ElabReflection
29+
30+ testFn : Nat
31+ testFn = %runElab (do debug {a = ()})
32+
33+when this is loaded the following is displayed:
34+
35+.. code-block:: idris
36+
37+ Holes:
38+ ----------------------------------
39+ {hole_2} : Prelude.Nat.Nat
40+
41+ ----------------------------------
42+ {hole_0} : Prelude.Nat.Nat
43+
44+ Term:
45+ ?{hole_0} ≈ ? {hole_2} . {hole_2} . {hole_0}
46+
47+This shows information about the state when debug is encountered, during tactic execution, which allows us to investigate what is happening at each stage.
48+
49+* The "Holes" part shows the types of the holes and the local context of each
50+* The "Term" part shows where these holes are in the expression being constructed.
51+
52+So starting with the "Term" part we have.
53+
54+.. code-block:: idris
55+
56+ ?{hole_0} ≈ ? {hole_2} . {hole_2} . {hole_0}
57+
58+.. sidebar:: attack tactic
59+
60+ This kind of thing tends to arise from "attack", which helps keep binding forms in order.
61+
62+The meaning of this is not immediately apparent so it helps to add some parentheses to make the structure clearer:
63+
64+.. code-block:: idris
65+
66+ (?{hole_0} ≈ (? {hole_2} . {hole_2}) . {hole_0})
67+
68+First lets look at the inner part:
69+
70+.. code-block:: idris
71+
72+ ? {hole_2} . {hole_2}
73+
74+We can substitute in the type from the "Holes" part:
75+
76+.. code-block:: idris
77+
78+ ? {hole_2}:Nat . {hole_2}:Nat
79+
80+So we are looking for a hole of type Nat and all we know is it has type Nat.
81+
82+Going back to the full term, the above is wrapped in a guess, so it means: 'a guess that is itself a hole'.
83+
84+Since the elaborator does not have any further information it has to be given a value:
85+
86+.. code-block:: idris
87+
88+ %language ElabReflection
89+
90+ testFn : Nat
91+ testFn = %runElab (do fill `(Z)
92+ debug {a = ()}
93+ solve)
94+
95+Now we have a guess for hole_2 which is itself a guess for hole_0:
96+
97+.. code-block:: idris
98+
99+ ?{hole_0} ≈ ?{hole_2} ≈ Prelude.Nat.Z . {hole_2} . {hole_0}
100+
101+The guesses can be accepted by calling the 'solve' tactic.
102+
103+Example Showing Patterns
104+------------------------
105+
106+In this next example a parameter 'n' has been added to the function. This allows us to see how patterns are used. Starting with this file:
107+
108+.. code-block:: idris
109+
110+ %language ElabReflection
111+
112+ testFn : Nat -> Nat
113+ testFn n = %runElab (do debug {a = ()})
114+
115+when loaded gives:
116+
117+.. code-block:: idris
118+
119+ Holes:
120+ n : Prelude.Nat.Nat
121+ ----------------------------------
122+ {hole_3} : Prelude.Nat.Nat
123+
124+ n : Prelude.Nat.Nat
125+ ----------------------------------
126+ {hole_1} : Prelude.Nat.Nat
127+
128+ ----------------------------------
129+ {hole_0} : patTy n : Prelude.Nat.Nat . Prelude.Nat.Nat
130+
131+ Term:
132+ ?{hole_0} ≈ pat n : Prelude.Nat.Nat .
133+ ?{hole_1} ≈ ? {hole_3} . {hole_3} . {hole_1} .
134+ {hole_0}
135+
136+The ns above the lines show the context of the holes on the right hand side - they include the variable n that is an argument!
137+
138+patTy is a binding form in Idris's core language that introduces a pattern variable. The idea is that the left-hand side and right-hand side of each pattern should have the same type. Because pattern variables may occur multiple times on either side of the equation, we can achieve this by documenting their types with a binding form that wraps each side. This new binding form is why an "attack" was necessary prior to elaborating the RHS.
139+
140+patTy is a type former, and pat is the corresponding introduction form. So you can think of patTy as being a bit like a dependent function type, and pat as being a bit like lambda, except they don't introduce functions (they instead are used for pattern-matching definitions).
141+
142+More Complicated Example
143+------------------------
144+
145+This example does not introduce any new notation but the extra complexity gives a more realistic idea of how it is used. Here we start with this file:
146+
147+.. code-block:: idris
148+
149+ %language ElabReflection
150+
151+ testFn : (n : Nat) -> (n = plus n Z) -> (S n = S (plus n Z))
152+ testFn k ih = %runElab (do debug {a = ()})
153+
154+when loaded gives:
155+
156+.. code-block:: idris
157+
158+ Holes:
159+ k : Prelude.Nat.Nat
160+ ih : = Prelude.Nat.Nat Prelude.Nat.Nat k
161+ (Prelude.Nat.plus k Prelude.Nat.Z)
162+ ----------------------------------
163+ {hole_4} : = Prelude.Nat.Nat Prelude.Nat.Nat (Prelude.Nat.S k)
164+ (Prelude.Nat.S (Prelude.Nat.plus k Prelude.Nat.Z))
165+
166+ k : Prelude.Nat.Nat
167+ ih : = Prelude.Nat.Nat Prelude.Nat.Nat k
168+ (Prelude.Nat.plus k Prelude.Nat.Z)
169+ ----------------------------------
170+ {hole_2} : = Prelude.Nat.Nat Prelude.Nat.Nat (Prelude.Nat.S k)
171+ (Prelude.Nat.S (Prelude.Nat.plus k Prelude.Nat.Z))
172+
173+ k : Prelude.Nat.Nat
174+ ----------------------------------

3+
4+.. list-table::
5+ :widths: 10 30
6+ :stub-columns: 1
7+
8+ * - gensym
9+ - Generate a unique name based on some hint.
10+
11+ Useful when establishing a new binder.
12+
13+ **NB**: the generated name is unique **for this run of the elaborator**.
14+
15+ Do not assume that they are globally unique.
16+
17+ Signature:
18+
19+ gensym : (hint : String) -> Elab TTName
20+
21+ * - solve
22+ - Substitute a guess into a hole.
23+
24+
25+ .. image:: ../image/solve.png
26+ :width: 141px
27+ :height: 74px
28+ :alt: diagram illustrating solve tactic
29+
30+
31+ Substitute the focused guess throughout its scope, eliminating it and moving focus to the next element of the hole queue. Fail if the focus is not a guess.
32+
33+ Signature:
34+
35+ solve : Elab ()
36+
37+ Example:
38+
39+ .. code-block:: idris
40+
41+ %language ElabReflection
42+
43+ testFn : Nat
44+ testFn = %runElab (do fill `(Z)
45+ solve)
46+
47+ * - fill
48+ - Place a term into a hole, unifying its type. Fails if the focus is not a hole.
49+
50+
51+ .. image:: ../image/fill.png
52+ :width: 140px
53+ :height: 74px
54+ :alt: diagram illustrating fill tactic
55+
56+
57+ Signature:
58+
59+ fill : (e : Raw) -> Elab ()
60+
61+ Place a term e with type tc into the focused hole:
62+
63+ ?h : th.e'
64+
65+ and convert it to a guess:
66+
67+ ?h ≈ e:t.e'
68+
69+ and fail if the current focus is not a hole. The type t of the guess is constructed by unifying tc and th, which may instantiate holes that they refer to. Fail if the current focus is not a hole or if unification fails.
70+
71+ This unification can result in the solution of further holes or the establishment of additional unsolved unification constraints.
72+
73+ Example:
74+
75+ .. code-block:: idris
76+
77+ %language ElabReflection
78+
79+ testFn : Nat
80+ testFn = %runElab (do fill `(Z)
81+ solve)
82+
83+ * - apply
84+ - Attempt to apply an operator to fill the current hole, potentially solving arguments by unification.
85+
86+ A hole is established for each argument.
87+
88+ The return value is the list of holes established for the arguments to the function.
89+
90+ Note that not all of the returned hole names still exist, as they may have been solved.
91+
92+ - @ op the term to apply
93+ - @ argSpec - A list of booleans, one for each argument that the operator will be applied to. If true then attempt to solve the argument by unification.
94+
95+ Signature:
96+
97+ apply : (op : Raw) -> (argSpec : List Bool) -> Elab (List TTName)
98+
99+ Example: elaborating an application of a function f that takes one implicit and two explicit arguments might invoke:
100+
101+ apply \`(f) [False, True, True]
102+
103+ Here is an example of an elab script that uses apply to insert the term plus Z (S Z) into a goal of type Nat.
104+
105+ .. code-block:: idris
106+
107+ do [x,y] <- apply `(plus) [False, False]
108+ solve
109+ focus x; fill `(Z); solve
110+ focus y; fill `(S Z); solve
111+
112+ The names of the established holes are returned.
113+
114+ Note: This was added to the original tactic language to allow elaborator reflection.
115+
116+ * - matchApply
117+ - Attempt to apply an operator to fill the current hole, potentially solving arguments by matching.
118+
119+ The return value is the list of holes established for the arguments to the function.
120+
121+ Note that not all of the returned hole names still exist, as they may have been solved.
122+
123+ - @ op the term to apply
124+ - @ argSpec instructions for finding the arguments to the term, where the Boolean states whether or not to attempt to solve the argument by matching.
125+
126+ Signature:
127+
128+ matchApply : (op : Raw) -> (argSpec : List Bool) -> Elab (List TTName)
129+
130+ * - focus
131+ - Move the focus to the specified hole, bringing it to the front of the hole queue. Fails if the hole does not exist.
132+
133+ @ hole the hole to focus on
134+
135+ Signature:
136+
137+ focus : (hole : TTName) -> Elab ()
138+
139+ * - unfocus
140+ - Send the currently-focused hole to the end of the hole queue and focus on the next hole.
141+
142+ Signature:
143+
144+ unfocus : TTName -> Elab ()
145+
146+ * - attack
147+ - Convert a hole to make it suitable for bindings.
148+
149+
150+ .. image:: ../image/attack.png
151+ :width: 152px
152+ :height: 70px
153+ :alt: diagram illustrating attack tactic
154+
155+
156+ The binding tactics require that a hole be directly under its binding, or else the scopes of the generated terms won't make sense. This tactic creates a new hole of the proper form, and points the old hole at it.
157+
158+ Signature:
159+
160+ attack : Elab ()
161+
162+ * - claim
163+ - Establish a new hole binding named n with type t, surrounding the current focus.
164+
165+ Introduce a new hole with a specified name and type.
166+
167+ The new hole will be focused, and the previously-focused hole will be immediately after it in the hole queue. Because this tactic introduces a new binding, you may need to 'attack' first.
168+
169+ Signature:
170+
171+ claim : TTName -> Raw -> Elab ()
172+
173+ * - patvar
174+ - Convert a hole into a pattern variable.
175+
176+ Signature:
177+
178+ patvar : TTName -> Elab ()
179+
180+ * - compute
181+ - Normalise the goal.
182+
183+ Often this is not necessary because normanisation is applied during other tactics.
184+
185+ Signature:
186+
187+ compute : Elab ()
188+
189+ * - normalise
190+ - Normalise a term in some lexical environment
191+
192+ - @ env the environment in which to compute (get one of these from `getEnv`)
193+ - @ term the term to normalise
194+
195+ Signature:
196+
197+ normalise : (env : List (TTName, Binder TT)) -> (term : TT) -> Elab TT
198+
199+ * - whnf
200+ - Reduce a closed term to weak-head normal form
201+
202+ @ term the term to reduce
203+
204+ Signature:
205+
206+ whnf : (term : TT) -> Elab TT
207+
208+ * - convertsInEnv
209+ - Check that two terms are convertible in the current context and in some environment.
210+
211+ - @ env a lexical environment to compare the terms in (see `getEnv`)
212+ - @ term1 the first term to convert
213+ - @ term2 the second term to convert
214+
215+ Signature:
216+
217+ convertsInEnv : (env : List (TTName, Binder TT)) -> (term1, term2 : TT) -> Elab ()
218+
219+ * - converts
220+ - Check that two terms are convertable in the current context and environment
221+
222+ - @ term1 the first term to convert
223+ - @ term2 the second term to convertconverts : (term1, term2 : TT) -> Elab ()
224+
225+ converts term1 term2 = convertsInEnv !getEnv term1 term2
226+
227+ * - getSourceLocation
228+ - Find the source context for the elaboration script
229+
230+ Signature:
231+
232+ getSourceLocation : Elab SourceLocation
233+
234+ * - sourceLocation
235+ - Attempt to solve the current goal with the source code
236+
237+ locationsourceLocation : Elab ()
238+
239+ .. code-block:: idris
240+
241+ sourceLocation = do loc <- getSourceLocation
242+ fill (quote loc)
243+ solve
244+
245+ * - currentNamespace
246+ - Get the current namespace at the point of tactic execution. This allows scripts to define top-level names conveniently.
247+
248+ The namespace is represented as a reverse-order list of strings, just as in the representation of names.
249+
250+ Signature:
251+
252+ currentNamespace : Elab (List String)
253+
254+ * - rewriteWith
255+ - Attempt to rewrite the goal using an equality.
256+
257+ The tactic searches the goal for applicable subterms, and constructs a context for `replace` using them. In some cases, this is not possible, and `replace` must be called manually with an appropriate context.
258+
259+ Because this tactic internally introduces a `let` binding, it requires that the hole be immediately under its binder (use 'attack' if it might not be).
260+
261+ Signature:
262+
263+ rewriteWith : Raw -> Elab ()
264+
265+ * - resolveTC
266+ - Attempt to solve the current goal with an interface dictionary
267+
268+ @ fn the name of the definition being elaborated (to prevent Idris from looping)
269+
270+ Signature:
271+
272+ resolveTC : (fn : TTName) -> Elab ()
273+
274+ * - search
275+ - Use Idris's internal proof search.
276+
277+ Signature:
278+
279+ search : Elab ()
280+
281+ * - search'
282+ - Use Idris's internal proof search, with more control.
283+
284+ - @ depth the search depth
285+ - @ hints additional names to try
286+
287+ Signature:
288+
289+ search' : (depth : Int) -> (hints : List TTName) -> Elab ()
290+
291+ * - operatorFixity
292+ - Look up the declared fixity for an operator.
293+
294+ The lookup fails if the operator does not yet have a fixity or if the string is not a valid operator.
295+
296+ @ operator the operator string to look up
297+
298+ Signature:
299+
300+ operatorFixity : (operator : String) -> Elab Fixity
301+
302+ * - debug
303+ - Halt elaboration, dumping the internal state for inspection.
304+
305+ This is intended for elaboration script developers, not for end-users. Use `fail` for final scripts.
306+
307+ Signature:
308+
309+ debug : Elab a
310+
311+ If 'debug' is not the last tactic then make sure its type is sufficiently constrained. In particular, its type is Elab a, but there's no way for Idris to find out which type was meant for a. This can be fixed by either writing an explicit type (e.g. debug {a = ()}) or by using a helper that constrains the type (such as simple in Pruviloj, e.g. simple debug as a line).
312+
313+ .. code-block:: idris
314+
315+ %language ElabReflection
316+
317+ idNat : Nat -> Nat
318+ idNat = %runElab (do intro `{{x}}
319+ debug {a = ()}
320+ fill (Var `{{x}})
321+ solve)
322+
323+ * - debugMessage
324+ - Halt elaboration, dumping the internal state and displaying a message.
325+
326+ This is intended for elaboration script developers, not for end-users. Use `fail` for final scripts.
327+
328+ @ msg the message to display
329+
330+ Signature:
331+
332+ debugMessage : (msg : List ErrorReportPart) -> Elab a
333+
334+ If 'debugMessage' is not the last tactic then make sure its type is sufficiently constrained. In particular, its type is Elab a, but there's no way for Idris to find out which type was meant for a. This can be fixed by either writing an explicit type (e.g. debugMessage [TextPart "message"] {a = ()}) or by using a helper that constrains the type (such as simple in Pruviloj, e.g. simple debug as a line).
335+
336+ .. code-block:: idris
337+
338+ %language ElabReflection
339+ idNat : Nat -> Nat
340+ idNat = %runElab (do intro `{{x}}
341+ debugMessage [TextPart "error message"] {a = ()}
342+ fill (Var `{{x}})
343+ solve)
344+
345+ * - metavar
346+ - Create a new top-level metavariable to solve the current hole.
347+
348+ @ name the name for the top-level variable
349+
350+ Signature:
351+
352+ metavar : (name : TTName) -> Elab ()
353+
354+ * - runElab
355+ - Recursively invoke the reflected elaborator with some goal.
356+
357+ The result is the final term and its type.

1+Elaborator Reflection - Tactics
2+===============================
3+
4+The Idris part of the code for elaborator reflection is in
5+Elab.idr `<https://github.com/idris-lang/Idris-dev/blob/master/libs/prelude/Language/Reflection/Elab.idr>`_
6+Before looking at the Elab monad we need to know how to construct terms.
7+
8+
9+Proof State
10+-----------
11+
12+The terminology 'Proof State' is used by analogy to proof assistants but, as used here, it's really more of a metaprogramming state.
13+
14+Tactics operate on the proof state. The proof state contains various pieces of information, at this stage, the important ones for us are:
15+
16+- A hole queue - This contains a list of the names of the holes used in the proof term. The solution to each hole may depend on the other holes. For more information about holes and guesses see `Dependently Typed Functional Programs and their Proofs by McBride 1999`_.
17+- A goal type - The type of the term that is under construction for the current goal.
18+- A possibly incomplete proof term, which is being calculated and should be the goal type at the end of elaboration.
19+- Context - A collection of open unification problems, representing recoverable failures of unification that may yet unify once more variables are solved.
20+
21+There are many other pieces of information in the proof state such as the names used , such as the bodies of case blocks that need to be elaborated.but, for now, we will leave the system to handle these.
22+

25+ :height: 232px
26+
27+Names TTName
28+------------
29+
30+Names in an Idris program are evaluated at runtime but sometimes a 'variable name' is needed, which can be referred to as an unevaluated symbol.
31+The names used in terms have different constructors depending on their type:
32+
33++---------------------------+-----------------------------------------------+
34+| UN String | A user-provided name |
35++---------------------------+-----------------------------------------------+
36+| NS (UN "foo") ["B", "A"]) | A name in some namespace |
37++---------------------------+-----------------------------------------------+
38+| MN Int String | Machine-chosen names |
39++---------------------------+-----------------------------------------------+

148+
149+There is a notation for a term in TT as it is being constructed (based on a BNF-like grammar), this is used for example in the debug output, it is a compact way to see the state of the term so it is used here.
150+So internally the program is stored as a tree structure using the following syntax:

255+Expression Syntax
256+-----------------
257+
258+There is a way of notating expressions such as those used in the proof state (example: goal type and proof terms) which is reasonably standard in the papers written about this subject.
259+
260+This notation is not entered directly by metaprogrammers but it is seen, for example in debug output. So this notation is explained here because it is useful to be familiar with it.
261+
262+The notation assumes right-associativity, in the absence of brackets, the term to the right binds more tightly than the one on the left.
263+So, for nested lambda terms:
264+
265++---------------+--------+-------------------+
266+| λ a . λ b . f | means | λ a .( λ b . f) |
267++---------------+--------+-------------------+
268+
269+and the same for function application:
270+
271++---------------+--------+-------------------+
272+| f g x | means | f (g x) |
273++---------------+--------+-------------------+
274+
275+In contrast, in lambda calculus, function application is usually regarded as left-associative,
276+Here are some typical examples of the notation used for expressions:
277+
278++-----------------------+
279+| ? {hole_0} . {hole_0} |
280++-----------------------+
281+
282+The term, to be derived, may start off in this state following something like this:
283+
284+.. code-block:: idris
285+
286+ myScript : Elab ()
287+ myScript= do
288+
289+The dot '.' tells us this is some sort of binding.
290+
291++----------------------------------------------+
292+| ?{hole_0} ≈ ? {hole_2} . {hole_2} . {hole_0} |
293++----------------------------------------------+
294+
295+This is a slightly more complicated example arising from:
296+
297+.. code-block:: idris
298+
299+ idNat : Nat -> Nat
300+ idNat = %runElab (do
301+
302+This introduces a guess that hole_0 = hole_2 .
303+
304++----------------------------------------------------+
305+| ?{hole_0} ≈ λ x . ? {hole_2} . {hole_2} . {hole_0} |
306++----------------------------------------------------+
307+
308+Following on from the previous example a lambda function is introduced like this:
309+
310+.. code-block:: idris
311+
312+ intro `{{x}}
313+
314+So now the expression is wrapped in a lambda binding.
315+
316++-------------------------------------------------------+
317+| ?{hole_0} ≈ λ x . ?{hole_2} ≈ x . {hole_2} . {hole_0} |
318++-------------------------------------------------------+
319+
320+Following on, we can use the fill tactic like this:
321+
322+.. code-block:: idris
323+
324+ fill (Var `{{x}})
325+
326+which introduces another guess.
327+
328++--------------------------------+
329+| ?{hole_0} ≈ λ x . x . {hole_0} |
330++--------------------------------+
331+
332+The solve tactic completes the proof
333+
334+Binders
335+-------
336+
337+Here we look at each tactic in turn to see how they affect the proof state.
338+
339+Introduction tactics for binders. The binder types are:
340+
341+- lambda function (intro)
342+- dependent function (forall)
343+- let (letBind)
344+- pattern (patbind)
345+
346+A precondition of these tactics is that the focused hole is of the form:
347+
348++-----------+
349+| ?h : t.h |
350++-----------+
351+
352+that is, that the body of its scope consists directly of a reference to the hole-bound variable. If a hole binder were of the form:
353+
354++--------------------+
355+| ?h : t1 -> t2.f h |
356++--------------------+
357+
358+and a tactic such as
359+
360++------------------+
361+| intro \`{{x}} |
362++------------------+
363+
364+were applied, the result would be the term
365+
366++---------------------------+
367+| ?h : t2 . λ x:t1. f h |
368++---------------------------+
369+
370+However this would cause the application of f to be ill-typed, as it expects an argument of type t1->t2, not an argument of type t2. Additionally, some binding tactics require that t, the type of the hole h, have a specific form, because the binder to be established may have a typing rule associated with it.

1+Many of the images in this directory have two files with the same name but a different extension:
2+
3+* The SVG file, being vector graphics, is best for drawing and modifying.
4+* The PNG file, being raster graphics, gives more consistent rendering.
5+
6+The image has therefore been generated as an SVG file and then exported to the PNG file.
7+
8+So, if you need to modify an image, I suggest the following sequence:
9+
10+* Edit the SVG file using a suitable editor (I use Inkscape).
11+* Export the changes to the PNG file, overwriting the old version.
12+* upload both files.
13+
14+Note, when exporting in Inkscape:
15+* Select everything first, this stops an enormous boundary being exported.
16+* After selecting the file to export to and clicking OK, don't forget to click on export button as well.

3+***************************
4+Parser Library Introduction
5+***************************
6+
7+The parser library can be used to build Idris structures from text. It involves a
8+certain amount of complexity and so it would typically be used for big projects.
9+An example might be a compiler for another language, written in Idris.
10+
11+Of course the parser library can also be used to compile to Idris, this is what
12+is done in Idris 2 and that is what the this library appears to have been
13+written for.
14+
15+So a secondary use for this tutorial would be to help understanding the internal
16+workings of Idris 2.
17+
18+The parser library is used in a similar way to Parsec which is a library for
19+writing parsers in Haskell. It is based on higher-order parser combinators, so a
20+complicated parser can be made out of many smaller ones.
21+
22+.. list-table::
23+
24+ * - This is a two stage process:
25+ - Lexer - This takes the input string and turns it into a list of Tokens.
26+ - Parser - This takes the list of tokens and outputs the code.
27+
28+ - .. image:: ../image/parserTopLevel.png
29+ :width: 307px
30+ :height: 76px
31+ :alt: diagram illustrating these stages of lexer and parser
32+
33+The advantage of using two stages, like this, is that things like whitespace and
34+comments don't need to be considered in every parser rule.
35+
36+The Idris parser library differs from Parsec in that you need to say, in the
37+Recogniser, whether a rule is guaranteed to consume input. This means that the
38+Idris type system prevents the construction of recognisers/rules that can't
39+consume the input.
40+
41+The Lexer is similar but works at the level of characters rather than tokens, and
42+you need to provide a TokenMap which defines how to build a token from
43+a string when a rule is matched.
44+
45+The following pages contain a tutorial for the :ref:`parserLibraryLexer` and a
46+tutorial for the :ref:`parserLibraryParser`. These tutorials have a running
47+example of a parser for integer expressions. This is a very simple example, there
48+may be easier ways to do something so simple, but it illustrates some of the
49+principles.
50+
51+Parser Library and Idris 2
52+--------------------------
53+
54+The parser library, in Idris 1, is almost the same as the code that the Idris 2
55+parser is built on. Even if you only want to use the Idris 1 parser library it
56+is useful to look at the code in the Idris 2 compilers to see how the library
57+can be used.
58+
59+Idris 2 has at least 3 compilers:
60+
61+- IDEMode - complies to SExp which is a Lisp-like structure used to communicate
62+ with external editors like Emacs and Vim.
63+- Idris.Parser - This is the main compiler which compiles from a file to
64+ PTerm (and eventually TT structure).
65+- REPL - compiles input from the command line.
66+
67+The following diagram is my first attempt to work out how some of the modules in
68+Idris 2 fit together (with a few of the dependencies between them shown). The
69+Idris 1 library is based on the modules at the bottom of the diagram (shown
70+in red).

3+Lexer
4+=====
5+
6+The lexer is run by calling the 'lex' function in the Text.Lexer.Core
7+module:
8+
9+.. code-block:: idris
10+
11+ lex : TokenMap a -> String -> (List (TokenData a), (Int, Int, String))
12+
13+.. list-table::

18+
19+ - .. image:: ../image/tokenise.png
20+ :width: 330px
21+ :height: 73px
22+ :alt: diagram illustrating these stages of lexer
23+
24+TokenMap
25+--------
26+
27+In order to construct this list of tokens we need:
28+
29+- A way to recognise the tokens in the input string.
30+- A way to construct these individual tokens.
31+
32+This is given by the TokenMap which is a list of pairs containing
33+this information:
34+
35+.. code-block:: idris
36+
37+ (Lexer, String -> tokenType)
38+
39+So for each Lexer in the list, if a substring in the input matches, run
40+the associated function to produce a token of type ``tokenType``
41+
42+.. list-table::
43+
44+ * - from Text.Lexer.Core
45+ : https://github.com/idris-lang/Idris-dev/blob/master/libs/contrib/Text/Lexer/Core.idr
46+
47+ - .. code-block:: idris
48+
49+ TokenMap : (tokenType : Type) -> Type
50+ TokenMap tokenType = List (Lexer, String -> tokenType)
51+
52+ * - We can create a tokenMap by using a function like this:
53+
54+ - .. code-block:: idris
55+
56+ myTokenMap : TokenMap Token
57+ myTokenMap = [(is 'a',CharLit)]
58+
59+Once we have a TokenMap we can use it to lex many strings.
60+
61+Recognisers
62+-----------
63+
64+The first part of each entry in the TokenMap is the recogniser.
65+
66+A simple recogniser is 'Pred' which uses a predicate (Char -> Bool) to
67+test whether to accept the character. It can be constructed using the
68+'is' function:
69+
70+.. code-block:: idris
71+
72+ *parserEx> is 'a'
73+ Pred (\ARG =>
74+ intToBool (prim__eqChar ARG 'a'))
75+ : Recognise True
76+
77+More complicated structures can be recognised as tokens, this is done using
78+the combinator structure of recognisers. This allows recognisers to be
79+combined, for example,
80+
81+.. list-table::
82+
83+ * - ``<+>`` means sequence two recognisers. If either consumes a character,
84+ the sequence is guaranteed to consume a character.
85+
86+ - .. code-block:: idris
87+
88+ *parserEx> is 'a' <+> is 'b'
89+ SeqEat (Pred (\ARG => intToBool (prim__eqChar ARG 'a')))
90+ (Delay (is 'b')) : Recognise True
91+
92+ * - ``<|>`` means if both consume, the combination is guaranteed
93+ to consumer a character:
94+
95+ - .. code-block:: idris
96+
97+ *parserEx> is 'a' <|> is 'b'
98+ Alt (Pred (\ARG => intToBool (prim__eqChar ARG 'a')))
99+ (Pred (\ARG => intToBool (prim__eqChar ARG 'b')))
100+ : Recognise True
101+
102+This diagram shows the recogniser combinator with some of its constructors:
103+
104+.. image:: ../image/recogniser.png
105+ :width: 487px
106+ :height: 249px
107+ :alt: recogniser data structure
108+
109+A recogniser consumes its input, that is it advances the index to its input
110+string, as it generates the token list. In some cases we don't want this to
111+happen, for instance, we may need to lookahead before consuming the input
112+string.
113+
114+If a recogniser does not consume input there is a danger of an infinite loop.
115+To prevent this the recogniser is dependent on a boolean called 'consumes' which
116+is true if the recogniser is guaranteed to consume at least one character.
117+
118+The constructors of Recognise allow us to ensure that, even though parts of
119+the recogniser may not consume, overall the recogniser will consume.
120+
121+Since 'Recognise True' is more common than 'Recognise False' it is convenient to
122+use 'Lexer' as a type synonym for 'Recognise True'.
123+
124+Whitespace and Comments
125+-----------------------
126+
127+An important reason to have a lexer is to simplify the parser when whitespace
128+or comments are required. Without this the parser would require a match for
129+every combination, with and without, whitespace and comments.
130+
131+In some languages the lexer needs to remove whitespace and comments so that
132+they don't appear in the token list. In some cases whitespace is significant
133+but a single whitespace token can stand for any number of spaces, tabs,
134+carriage returns and so on.
135+
136+In some cases, such as when parsing the Idris language itself, whitespace
137+is important to indicate blocks. In this case we might want to output a
138+start-of-block token when the indent increases and an end-of-block token
139+when the indent decreases.
140+
141+This topic will be discussed more fully on this page
142+:ref:`parserLibraryWhitespace`.
143+
144+Simple Expression Example for Lexer
145+-----------------------------------
146+
147+On this page we will implement a lexer to 'lex' a very simple expression as
148+a running example, on the next page, we will go on to implement a parser for it.
149+
150+First import the lexer and parser code:
151+
152+.. code-block:: idris
153+
154+ module ParserExample
155+
156+ import Text.Lexer
157+ import public Text.Parser.Core
158+ import public Text.Parser
159+
160+Then decide on the tokens that are needed. For this example the idea is to be
161+able to parse simple arithmetic expressions, like this:
162+
163+.. code-block:: idris
164+
165+ 1+(2*3)
166+
167+so we need:
168+
169+- Numbers (for now integer literals are good enough).
170+- Some operators (for now ``+``, ``-`` and ``*`` will do.
171+- Opening and closing Parentheses.
172+
173+We can define these, as tokens, like this:
174+
175+.. code-block:: idris
176+
177+ %default total
178+
179+ public export
180+ data ExpressionToken = Number Integer
181+ | Operator String
182+ | OParen
183+ | CParen
184+ | EndInput
185+
186+It may help with debugging and to implement error messages to
187+implement ``show`` for these tokens:
188+
189+.. code-block:: idris
190+
191+ export
192+ Show ExpressionToken where
193+ show (Number x) = "number " ++ show x
194+ show (Operator x) = "operator " ++ x
195+ show OParen = "("
196+ show CParen = ")"
197+ show EndInput = "end of input"
198+
199+ export
200+ Show (TokenData ExpressionToken) where
201+ show (MkToken l c t) = "line=" ++ show l ++ " col=" ++ show c ++ "tok=" ++ show t
202+
203+The following defines the 'TokenMap' for this example:
204+
205+.. code-block:: idris
206+
207+ ||| integer arithmetic operators plus, minus and multiply.
208+ export
209+ opChars : String
210+ opChars = "+-*"
211+
212+ operator : Lexer
213+ operator = some (oneOf opChars)
214+
215+ toInt' : String -> Integer
216+ toInt' = cast
217+
218+ expressionTokens : TokenMap ExpressionToken
219+ expressionTokens =
220+ [(digits, \x => Number (toInt' x)),
221+ (operator, \x => Operator x),
222+ (is '(' ,\x => OParen),
223+ (is ')' ,\x => CParen)]
224+
225+This specifies the lexer. It gives, for each token, a function to recognise
226+the token type and a function to construct the token.
227+
228+The library module 'Text.Lexer' contains useful functions to help with this.
229+For example, the digits function used above, which reads one or more
230+numeric characters.
231+
232+We can now run the code with various strings to see what output the lexer
233+produces. This is done by calling the 'lex' function with the TokenMap and
234+input string as parameters:
235+

262+ (Operator "+"),

272+ getString (MkStrLen "" 0)) : (List (TokenData ExpressionToken),
273+ Int,
274+ Int,
275+ String)
276+
277+The lexer uses potentially infinite data structures. It has recursive
278+arguments (codata type) so code is lazy. In the output above the indexes
279+have not been computed but we can pick out the tokens:
280+
281+- (Number 1)
282+- (Operator "+")
283+- (Number 2)
284+
285+So the code is working.
286+
287+We can now go ahead and parse this token list. A parser for this example will
288+be constructed on the next page.

47+ SeqEat : Grammar tok True a -> Inf (a -> Grammar tok c2 b) ->
48+ Grammar tok True b
49+ SeqEmpty : {c1, c2 : Bool} ->
50+ Grammar tok c1 a -> (a -> Grammar tok c2 b) ->
51+ Grammar tok (c1 || c2) b
52+ Alt : {c1, c2 : Bool} ->
53+ Grammar tok c1 ty -> Grammar tok c2 ty ->
54+ Grammar tok (c1 && c2) ty
55+
56+So an example of a grammer type may look something like this:
57+``Grammar (TokenData ExpressionToken) True Integer``.
58+This is a complicated type name and a given parser will need to use it a lot.
59+So to reduce the amount of typing we can use the following type synonym (similar
60+to what is done in Idris 2
61+: https://github.com/edwinb/Idris2/blob/master/src/Parser/Support.idr
62+)
63+
64+.. code-block:: idris
65+
66+ public export
67+ Rule : Type -> Type
68+ Rule ty = Grammar (TokenData ExpressionToken) True ty
69+
70+Parser Example
71+--------------
72+
73+On the previous page we implemented a lexer to 'lex' a very simple expression, on
74+this page we will go on to add a parser for this running example.
75+
76+.. list-table::
77+
78+ * - The syntax we are aiming at is something
79+ like this (expressed in Backus–Naur form (BNF)):
80+ - .. code-block:: idris
81+
82+ <expr> ::= <integer literal>
83+ | <expr>'+'<expr>
84+ | <expr>'-'<expr>
85+ | <expr>'*'<expr>
86+ | '('<expr>')'
87+
88+ <integer literal> ::= <digit>|<integer literal><digit>
89+
90+.. list-table::
91+
92+ * - To start, here is a grammar to parse an integer literal (that is, a
93+ sequence of numeric characters).
94+
95+ - .. code-block:: idris
96+
97+ export
98+ intLiteral : Rule Integer
99+ intLiteral
100+ = terminal (\x => case tok x of
101+ Number i => Just i
102+ _ => Nothing)
103+
104+In order to try this out, here is a temporary function, this calls
105+parse which takes two parameters:
106+
107+- The grammar (in this case intLiteral)
108+- The token list from the lexer.
109+
110+.. code-block:: idris
111+
112+ test1 : String -> Either (ParseError (TokenData ExpressionToken))
113+ (Integer, List (TokenData ExpressionToken))
114+ test1 s = parse intLiteral (fst (lex expressionTokens s))
115+
116+As required, if we pass it a string which is a number literal then it will
117+return the number in the 'Right' option.
118+
119+.. code-block:: idris
120+
121+ *parserEx> test1 "123"
122+ Right (123, []) : Either (ParseError (TokenData ExpressionToken))
123+ (Integer, List (TokenData ExpressionToken))
124+
125+If we pass it a string which is not a number literal then it will return an
126+error message.
127+
128+.. code-block:: idris
129+
130+ *parserEx> test1 "a"
131+ Left (Error "End of input"
132+ []) : Either (ParseError (TokenData ExpressionToken))
133+ (Integer, List (TokenData ExpressionToken))
134+
135+If we pass it a number followed by something else, then it will still be
136+successful, this is because we are not specifically checking for end-of-file.
137+
138+.. code-block:: idris
139+
140+ *parserEx> test1 "123a"
141+ Right (123, []) : Either (ParseError (TokenData ExpressionToken))
142+ (Integer, List (TokenData ExpressionToken))
143+ *parserEx>
144+
145+.. list-table::
146+
147+ * - The ``intLiteral`` function above uses the ``terminal`` function to
148+ construct the grammar
149+ - .. code-block:: idris
150+
151+ ||| Succeeds if running the predicate on the
152+ ||| next token returns Just x, returning x.
153+ ||| Otherwise fails.
154+ export
155+ terminal : (tok -> Maybe a) -> Grammar tok True a
156+ terminal = Terminal
157+
158+This is defined here
159+: https://github.com/idris-lang/Idris-dev/blob/master/libs/contrib/Text/Parser/Core.idr
160+Idris 2 uses a slightly different version which stores an error message like
161+"Expected integer literal" which can be output if the rule fails
162+: https://github.com/edwinb/Idris2/blob/master/src/Text/Parser/Core.idr
163+
164+.. list-table::
165+
166+ * - The 'terminal' function is also used to construct the other
167+ elements of the grammar that we require, for instance,
168+ opening parenthesis:
169+
170+ - .. code-block:: idris
171+
172+ openParen : Rule Integer
173+ openParen = terminal (\x => case tok x of
174+ OParen => Just 0
175+ _ => Nothing)
176+
177+Integer value is not really relevant for parenthesis so ``0`` (zero) is used as
178+a default value.
179+
180+As before, this can be tested with a function like this:
181+
182+.. code-block:: idris
183+
184+ test2 : String -> Either (ParseError (TokenData ExpressionToken))
185+ (Integer, List (TokenData ExpressionToken))
186+ test2 s = parse openParen (fst (lex expressionTokens s))
187+
188+We can see below that it correctly parses an open parenthesis and gives an
189+error for anything else:
190+
191+.. code-block:: idris
192+
193+ *parserEx> test2 "("
194+ Right (0, []) : Either (ParseError (TokenData ExpressionToken))
195+ (Integer, List (TokenData ExpressionToken))
196+ *parserEx> test2 "123"
197+ Left (Error "Unrecognised token"
198+ [MkToken 0
199+ 0
200+ (Number 123)]) : Either (ParseError (TokenData ExpressionToken))
201+ (Integer,
202+ List (TokenData ExpressionToken))
203+
204+Now we have two Grammars we can try combining them. The following test looks
205+for ``openParen`` followed by ``intLiteral``, the two Grammars are combined using
206+``<*>``. The ``map const`` part uses the integer value from the first.
207+
208+The following test is looking for ``(`` followed by a number:
209+
210+.. code-block:: idris
211+
212+ test3 : String -> Either (ParseError (TokenData ExpressionToken))
213+ (Integer, List (TokenData ExpressionToken))
214+ test3 s = parse (map const openParen <*> intLiteral) (fst (lex expressionTokens s))
215+
216+We can see below that ``(`` followed by a number is successfully parsed but, as
217+required, other token lists are not:
218+
219+.. code-block:: idris
220+
221+ *parserEx> test3 "(123"
222+ Right (0, []) : Either (ParseError (TokenData ExpressionToken))
223+ (Integer, List (TokenData ExpressionToken))
224+ *parserEx> test3 "(("
225+ Left (Error "Unrecognised token"
226+ [MkToken 0
227+ (case fspan (\ARG => not (intToBool (prim__eqChar ARG '\n')))
228+ "(" of
229+ (incol, "") => c + cast (length incol)
230+ (incol, b) => cast (length incol))
231+ OParen]) : Either (ParseError (TokenData ExpressionToken))
232+ (Integer, List (TokenData ExpressionToken))
233+
234+ *parserEx> test3 "123"
235+ Left (Error "Unrecognised token"
236+ [MkToken 0
237+ 0
238+ (Number 123)]) : Either (ParseError (TokenData ExpressionToken))
239+ (Integer,
240+ List (TokenData ExpressionToken))
241+ *parserEx> test3 "123("
242+ Left (Error "Unrecognised token"
243+ [MkToken 0 0 (Number 123),
244+ MkToken 0
245+ (case fspan (\ARG => not (intToBool (prim__eqChar ARG '\n')))
246+ "321" of
247+ (incol, "") => c + cast (length incol)
248+ (incol, b) => cast (length incol))
249+ OParen]) : Either (ParseError (TokenData ExpressionToken))
250+ (Integer, List (TokenData ExpressionToken))
251+
252+.. list-table::
253+
254+ * - The closing parenthesis is constructed in the same way.
255+
256+ - .. code-block:: idris
257+
258+ closeParen : Rule Integer
259+ closeParen = terminal (\x => case tok x of
260+ CParen => Just 0
261+ _ => Nothing)
262+
263+.. list-table::
264+
265+ * - Now we can generate a Grammar for an expression inside parenthesis
266+ like this.
267+
268+ - .. code-block:: idris
269+
270+ paren : Rule Integer -> Rule Integer
271+ paren exp = openParen *> exp <* closeParen
272+
273+The use of ``*>`` and ``<*`` instead of ``<*>`` is an easy way to use the integer
274+value from the inner expression.
275+
276+So lets try to use this to define a grammar which recognises either:
277+
278+- An integer literal
279+- An integer literal inside parenthesis
280+- An integer literal inside parenthesis inside parenthesis
281+- ... and so on.
282+
283+.. list-table::
284+
285+ * - This requires a recursively defined structure like this:
286+
287+ - .. code-block:: idris
288+
289+ partial
290+ expr : Rule Integer
291+ expr = intLiteral <|> (paren expr)
292+
293+This is a valid grammar because every time it is called it is guaranteed to
294+consume a token. However, as an Idris structure, it is problematic due to
295+the recursion. Defining it as partial allows it to compile but at runtime
296+we are likely to get a crash with an (unhelpful) error message like
297+``killed by signal 11``.
298+
299+So a better method is to use ``do`` notation as described in the following
300+section.
301+
302+Monadic Combinator
303+------------------
304+
305+In addition to ``<|>`` and ``<*>`` there is a ``>>=`` combinator, which is
306+defined like this:
307+
308+.. code-block:: idris
309+
310+ ||| Sequence two grammars. If either consumes some input, the sequence is
311+ ||| guaranteed to consume some input. If the first one consumes input, the
312+ ||| second is allowed to be recursive (because it means some input has been
313+ ||| consumed and therefore the input is smaller)
314+ export %inline
315+ (>>=) : {c1 : Bool} ->
316+ Grammar tok c1 a ->
317+ inf c1 (a -> Grammar tok c2 b) ->
318+ Grammar tok (c1 || c2) b
319+ (>>=) {c1 = False} = SeqEmpty
320+ (>>=) {c1 = True} = SeqEat
321+
322+.. list-table::
323+
324+ * - This allows us to use ``do`` notation for the previous parenthesis example:
325+
326+ - .. code-block:: idris
327+
328+ expr = intLiteral <|> do
329+ openParen
330+ r <- expr
331+ closeParen
332+ pure r
333+
334+This can be more flexible than using the ``<*>`` operator. Also it is defined
335+using ``Inf`` so we can implement recursively defined grammars as above.
336+
337+Implementing the Arithmetic Operators
338+-------------------------------------
339+
340+.. list-table::
341+
342+ * - Now for the operations, in this case: ``+``, ``-`` and ``*``.
343+ The syntax we require for these infix operators
344+ would require recursive grammars like this:
345+
346+ - .. code-block:: idris
347+
348+ expr = expr (op "+") expr
349+
350+As already explained, ``do`` notation can allow us to use recursive
351+definitions but not necessarily left-recursion like this.
352+
353+In order to work up to this gradually lets start with prefix operators
354+(sometimes known as Polish notation) then modify later for infix operators.
355+
356+.. list-table::
357+
358+ * - So prefix operators would have this sort of form:
359+
360+ - .. code-block:: idris
361+
362+ expr = (add (op "+") expr expr)
363+
364+where ``op`` is defined like this:
365+
366+.. code-block:: idris
367+
368+ ||| Matches if this is an operator token and string matches, that is,
369+ ||| it is the required type of operator.
370+ op : String -> Rule Integer
371+ op s = terminal (\x => case tok x of
372+ (Operator s1) => if s==s1 then Just 0 else Nothing
373+ _ => Nothing)
374+
375+.. list-table::
376+
377+ * - and ``add`` is defined like this:
378+
379+ Where:
380+
381+ - x is the add operator.
382+ - y is the first operand.
383+ - z is the second operand.
384+
385+ - .. code-block:: idris
386+
387+ addInt : Integer -> Integer -> Integer
388+ addInt a b = a+b
389+
390+ export
391+ add : Grammar tok c1 Integer ->
392+ Grammar tok c2 Integer ->
393+ Grammar tok c3 Integer ->
394+ Grammar tok ((c1 || c2) || c3) Integer
395+ add x y z = map addInt (x *> y) <*> z
396+
397+
398+
399+The resulting integer will be the sum of the two operands.
400+
401+.. list-table::
402+
403+ * - The other operators are defined in a similar way:
404+
405+ - .. code-block:: idris
406+
407+ subInt : Integer -> Integer -> Integer
408+ subInt a b = a-b
409+
410+ export
411+ sub : Grammar tok c1 Integer ->
412+ Grammar tok c2 Integer ->
413+ Grammar tok c3 Integer ->
414+ Grammar tok ((c1 || c2) || c3) Integer
415+ sub x y z = map subInt (x *> y) <*> z
416+
417+ multInt : Integer -> Integer -> Integer
418+ multInt a b = a*b
419+
420+ export
421+ mult : Grammar tok c1 Integer ->
422+ Grammar tok c2 Integer ->
423+ Grammar tok c3 Integer ->
424+ Grammar tok ((c1 || c2) || c3) Integer
425+ mult x y z = map multInt (x *> y) <*> z
426+
427+So the top level ``Grammar`` can now be defined as follows. Note that this is
428+partial as it is a potentially infinite structure and so not total.
429+
430+.. code-block:: idris
431+
432+ partial
433+ expr : Rule Integer
434+ expr = (add (op "+") expr expr)
435+ <|> (sub (op "-") expr expr)
436+ <|> (mult (op "*") expr expr)
437+ <|> intLiteral <|> (paren expr)
438+
439+.. list-table::
440+
441+ * - To make the testing easier we can use this function:
442+
443+ - .. code-block:: idris
444+
445+ partial
446+ test : String -> Either (ParseError (TokenData ExpressionToken))
447+ (Integer, List (TokenData ExpressionToken))
448+ test s = parse expr (fst (lex expressionTokens s))
449+
450+.. list-table::
451+
452+ * - First test a valid (prefix) expression:
453+
454+ - .. code-block:: idris
455+
456+ *parserEx> test "+1*6(4)"
457+ Right (25,
458+ []) : Either (ParseError (TokenData ExpressionToken))
459+ (Integer, List (TokenData ExpressionToken))
460+
461+Then an invalid syntax:
462+
463+.. code-block:: idris
464+
465+ *parserEx> test "))"
466+ Left (Error "Unrecognised token"
467+ [MkToken 0 0 CParen,
468+ MkToken 0
469+ (case fspan (\ARG =>
470+ not (intToBool (prim__eqChar ARG
471+ '\n')))
472+ ")" of
473+ (incol, "") => c + cast (length incol)
474+ (incol, b) => cast (length incol))
475+ CParen]) : Either (ParseError (TokenData ExpressionToken))
476+ (Integer,
477+ List (TokenData ExpressionToken))
478+
479+However if we try something that is invalid, but starts with a valid token,
480+then it will return ``Right`` (to indicate success)
481+
482+.. code-block:: idris
483+
484+ *parserEx> test "1))"
485+ Right (1,
486+ [MkToken 0
487+ (case fspan (\ARG =>
488+ not (intToBool (prim__eqChar ARG '\n')))
489+ "1" of
490+ (incol, "") => c + cast (length incol)
491+ (incol, b) => cast (length incol))
492+ CParen,
493+ MkToken 0
494+ (case fspan (\ARG =>
495+ not (intToBool (prim__eqChar ARG '\n')))
496+ ")" of
497+ (incol, "") => c + cast (length incol)
498+ (incol, b) => cast (length incol))
499+ CParen]) : Either (ParseError (TokenData ExpressionToken))
500+ (Integer,
501+ List (TokenData ExpressionToken))
502+
503+Infix Notation
504+--------------
505+
506+So far we have implemented a prefix notation for operators (like this:
507+``+ expr expr``) but the aim is to implemented an infix notation (like this:
508+``expr + expr``). To do this we must be able to deal with potentially
509+infinite data structures (see Codata Types here :ref:`sect-typefuns`).
510+
511+First alter the grammar to have infix operations:
512+
513+.. code-block:: idris
514+
515+ addInt : Integer -> Integer -> Integer
516+ addInt a b = a+b
517+
518+ export
519+ add : Grammar tok c1 Integer ->
520+ Grammar tok c2 Integer ->
521+ Grammar tok c3 Integer ->
522+ Grammar tok ((c1 || c2) || c3) Integer
523+ add x y z = map addInt (x <* y) <*> z
524+
525+ subInt : Integer -> Integer -> Integer
526+ subInt a b = a-b
527+
528+ export
529+ sub : Grammar tok c1 Integer ->
530+ Grammar tok c2 Integer ->
531+ Grammar tok c3 Integer ->
532+ Grammar tok ((c1 || c2) || c3) Integer
533+ sub x y z = map subInt (x <* y) <*> z
534+
535+
536+ multInt : Integer -> Integer -> Integer
537+ multInt a b = a*b
538+
539+ export
540+ mult : Grammar tok c1 Integer ->
541+ Grammar tok c2 Integer ->
542+ Grammar tok c3 Integer ->
543+ Grammar tok ((c1 || c2) || c3) Integer
544+ mult x y z = map multInt (x <* y) <*> z
545+
546+ partial
547+ expr : Rule Integer
548+ expr = (add expr (op "+") expr)
549+ <|> (sub expr (op "-") expr)
550+ <|> (mult expr (op "*") expr)
551+ <|> intLiteral <|> (paren expr)
552+
553+However, if this was run, the code would not terminate.
554+
555+Implement Left Recursion Elimination
556+------------------------------------
557+
558+Left factoring, like this, is a general problem.
559+
560+If we have a rule like this:
561+
562+.. code-block:: idris
563+
564+ A -> (x<*>y) <|> (x<*>z)
565+
566+If ``x<*>y`` fails but ``x<*>z`` would succeed a problem is that, ``x<*>y`` has
567+already consumed ``x``, so now ``x<*>z`` will fail.
568+
569+so we could write code to backtrack. That is ``try`` ``x<*>y`` without consuming
570+so that, if the first token succeeds but the following tokens fail, then the
571+first tokens would not be consumed.
572+
573+Another approach is left factoring:
574+
575+Left Factoring
576+--------------
577+
578+Replace the rule with two rules (that is we add a non-terminal symbol) so
579+for example, instead of:
580+
581+.. code-block:: idris
582+
583+ A -> (x<*>y) <|> (x<*>z)
584+
585+we add an extra rule to give:
586+
587+.. code-block:: idris
588+
589+ A -> x<*>N
590+ N -> y <|> z
591+
592+That is we convert a general context-free grammar to a LL(1) grammar. Although
593+not every context-free grammar can be converted to a LL(1) grammar.
594+
595+This still does not solve the infinite recursion issue and there is another
596+problem: the precedence of the operators ``+``, ``-`` and ``*`` is not explicit.
597+
598+.. list-table::
599+
600+ * - To resolve this we can alter the example to have a BNF like this:
601+ Where braces ``{ ... }`` mean the contents can occur 1 or more times.
602+
603+ - .. code-block:: idris
604+
605+ 'expression' ::= ('+'|'-') 'term' {('+'|'-') 'term'}
606+
607+ 'term' ::= 'factor' {'*' 'factor'}
608+
609+ 'factor' ::=
610+ number
611+ | '(' 'expression' ')'
612+
613+
614+.. code-block:: idris
615+
616+ expr : Rule Integer
617+
618+ factor : Rule Integer
619+ factor = intLiteral <|> do
620+ openParen
621+ r <- expr
622+ closeParen
623+ pure r
624+
625+ term : Rule Integer
626+ term = map multInt factor <*> (
627+ (op "*")
628+ *> factor)
629+ <|> factor
630+
631+ expr = map addInt term <*> (
632+ (op "+")
633+ *> term)
634+ <|> map subInt term <*> (
635+ (op "-")
636+ *> term)
637+ <|> term
638+
639+ calc : String -> Either (ParseError (TokenData ExpressionToken))
640+ (Integer, List (TokenData ExpressionToken))

670+
671+ *algebraREPL> :exec
672+ alg>2
673+ right (2, [])
674+
675+ * - Check that '*' has a higher precedence than '+'.
676+
677+ - .. code-block:: idris
678+
679+ *algebraREPL> :exec
680+ alg>2+3*4
681+ right (14, [])
682+
683+ * - Also '*' has a higher precedence than '+' when the order is reversed.
684+
685+ - .. code-block:: idris
686+
687+ *algebraREPL> :exec
688+ alg>3*4+2

694+
695+ *algebraREPL> :exec
696+ alg>(2+3)*4
697+ right (20, [])
698+
699+This is still not correct because it does not correctly parse multiple sums or terms
700+like ``1+2+3`` or ``1*2*3``.

3+Whitespace and Comments
4+=======================
5+
6+The previous two pages introduced the lexer and parser but have not yet
7+discussed how to handle whitespace and comments.
8+
9+In some grammars whitespace and comments would not be considered significant and
10+so we might be tempted not to generate any tokens for them. However, in the
11+running example, we may want to make spaces significant in the future. For
12+example, we might want to implement function application expressed by
13+juxtaposition as in Haskell and Idris like this: ``f x``.
14+
15+So, on this page, we will add a token for whitespace and comments. We will
16+then consider two ways to process this:
17+
18+- Filter all whitespace tokens from the lexer results before passing to
19+ the parser.
20+- Process the whitespace tokens in the parser.
21+
22+Whitespace and Comments in Lexer
23+--------------------------------
24+
25+To start with we can use the same token for both whitespace and comments. Here
26+it is called ``Comment`` and added to the ``ExpressionToken`` data structure
27+like this:
28+
29+.. code-block:: idris
30+
31+ public export
32+ data ExpressionToken = Number Integer
33+ | Operator String
34+ | OParen
35+ | CParen
36+ | Comment String
37+ | EndInput
38+
39+This is added to the ``TokenMap`` like this:
40+
41+.. code-block:: idris
42+
43+ ||| from https://github.com/edwinb/Idris2/blob/master/src/Parser/Lexer.idr
44+ comment : Lexer
45+ comment = is '-' <+> is '-' <+> many (isNot '\n')
46+
47+ expressionTokens : TokenMap ExpressionToken
48+ expressionTokens =
49+ [(digits, \x => Number (toInt' x)),
50+ (operator, \x => Operator x),
51+ (is '(' ,\x => OParen),
52+ (is ')' ,\x => CParen),
53+ (spaces, Comment),
54+ (comment, Comment)]
55+
56+As you can see, the comment is defined like a single line Idris comment,
57+it starts with ``--`` and continues for the remainder of the line.
58+
59+We don't need to define ``spaces`` because it is already defined in
60+: https://github.com/idris-lang/Idris-dev/blob/master/libs/contrib/Text/Lexer.idr
61+like this:
62+
63+.. code-block:: idris
64+
65+ ||| Recognise a single whitespace character
66+ ||| /\\s/
67+ space : Lexer
68+ space = pred isSpace
69+
70+ ||| Recognise one or more whitespace characters
71+ ||| /\\s+/
72+ spaces : Lexer
73+ spaces = some space
74+
75+If these whitespace tokens are not significant, that is, they can appear
76+anywhere and they are optional then we can filter them out before the parser
77+gets them like this:
78+
79+.. code-block:: idris
80+
81+ processWhitespace : (List (TokenData ExpressionToken), Int, Int, String)
82+ -> (List (TokenData ExpressionToken), Int, Int, String)
83+ processWhitespace (x,l,c,s) = ((filter notComment x),l,c,s) where
84+ notComment : TokenData ExpressionToken -> Bool
85+ notComment t = case tok t of
86+ Comment _ => False
87+ _ => True
88+
89+ calc : String -> Either (ParseError (TokenData ExpressionToken))
90+ (Integer, List (TokenData ExpressionToken))
91+ calc s = parse expr (fst (processWhitespace (lex expressionTokens s)))
92+
93+
94+Whitespace and Comments in Parser
95+---------------------------------
96+
97+If we sometimes require whitespace to be significant then we can't filter
98+them out as above. In this case the ``Comment`` tokens are sent to the parser
99+which now needs to be able to handle them.
100+
101+.. code-block:: idris
102+
103+ commentSpace : Rule Integer
104+ commentSpace = terminal (\x => case tok x of
105+ Comment s => Just 0
106+ _ => Nothing)
107+
108+So far we don't have any syntax that requires spaces to be significant so we
109+need to define the grammar so that it will parse with, or without, spaces.
110+This needs to be done in a systematic way, here I have defined the grammar so
111+that there is an optional space to the right of every atom or operator.
112+First add versions of ``intLiteral`` , ``openParen`` , ``closeParen``
113+and ``op`` that allow optional spaces/comments to the right of them:
114+
115+.. code-block:: idris
116+
117+ intLiteralC : Rule Integer
118+ intLiteralC = (intLiteral <* commentSpace) <|> intLiteral
119+
120+ openParenC : Rule Integer
121+ openParenC = (openParen <* commentSpace) <|> openParen
122+
123+ closeParenC : Rule Integer
124+ closeParenC = (closeParen <* commentSpace) <|> closeParen
125+
126+ ||| like op but followed by optional comment or space
127+ opC : String -> Rule Integer
128+ opC s = ((op s) <* commentSpace) <|> (op s)
129+
130+Then just use these functions instead of the original functions:
131+
132+.. code-block:: idris
133+
134+ expr : Rule Integer
135+
136+ factor : Rule Integer
137+ factor = intLiteralC <|> do
138+ openParenC
139+ r <- expr
140+ closeParenC
141+ pure r
142+
143+ term : Rule Integer
144+ term = map multInt factor <*> (
145+ (opC "*")
146+ *> factor)
147+ <|> factor
148+
149+ expr = map addInt term <*> (
150+ (opC "+")
151+ *> term)
152+ <|> map subInt term <*> (
153+ (opC "-")
154+ *> term)
155+ <|> term
156+
157+ calc : String -> Either (ParseError (TokenData ExpressionToken))
158+ (Integer, List (TokenData ExpressionToken))
159+ calc s = parse expr (fst (lex expressionTokens s))
160+
161+ lft : (ParseError (TokenData ExpressionToken)) -> IO ()
162+ lft (Error s lst) = putStrLn ("error:"++s)
163+
164+ rht : (Integer, List (TokenData ExpressionToken)) -> IO ()
165+ rht i = putStrLn ("right " ++ (show i))
166+
167+ main : IO ()
168+ main = do
169+ putStr "alg>"
170+ x <- getLine
171+ either lft rht (calc x) -- eliminator for Either
172+
173+
174+Defining Block Structure using Indents
175+--------------------------------------
176+
177+Many languages such as Python, Haskell and Idris use indents to delimit
178+the block structure of the language.
179+
180+We can see how Idris2 does it here
181+: https://github.com/edwinb/Idris2/blob/master/src/Parser/Support.idr
182+
183+.. code-block:: idris
184+
185+ export
186+ IndentInfo : Type
187+ IndentInfo = Int
188+
189+ export
190+ init : IndentInfo
191+ init = 0
192+
193+EndInput Token
194+--------------
195+
196+So far, the parser will return a successful result even if the full input
197+is not consumed. To ensure that the top level syntax is fully matched we
198+add a ``EndInput`` token to indicate the last token.
199+
200+``EndInput`` is added to the other tokens like this:
201+
202+.. code-block:: idris
203+
204+ data ExpressionToken = Number Integer
205+ | Operator String
206+ | OParen
207+ | CParen
208+ | Comment String
209+ | EndInput
210+
211+A rule to consume this token is added:
212+
213+.. code-block:: idris
214+
215+ eoi : Rule Integer
216+ eoi = terminal (\x => case tok x of
217+ EndInput => Just 0
218+ _ => Nothing)
219+
220+Instead of using ``expr`` at the top level of the syntax we can now define
221+``exprFull`` as shown here. This will make sure that only when ``EndInput``
222+is consumed will the parse be successful:
223+
224+.. code-block:: idris
225+
226+ exprFull : Rule Integer
227+ exprFull = expr <* eoi
228+
229+The following code makes sure ``EndInput`` is added to the end of the token
230+list:
231+
232+.. code-block:: idris
233+
234+ processWhitespace : (List (TokenData ExpressionToken), Int, Int, String)
235+ -> (List (TokenData ExpressionToken), Int, Int, String)
236+ processWhitespace (x,l,c,s) = ((filter notComment x)++
237+ [MkToken l c EndInput],l,c,s) where
238+ notComment : TokenData ExpressionToken -> Bool
239+ notComment t = case tok t of
240+ Comment _ => False
241+ _ => True
242+
243+All we have to do now is use ``exprFull`` instead of ``expr``:
244+
245+.. code-block:: idris
246+
247+ calc : String -> Either (ParseError (TokenData ExpressionToken))
248+ (Integer, List (TokenData ExpressionToken))
249+ calc s = parse exprFull (fst (processWhitespace (lex expressionTokens s)))

2+Background Material
3+*******************
4+
5+In order to understand how to write proofs in Idris I think its worth clarifying some fundamentals, such as,
6+
7+- Propositions and judgments
8+- Boolean and constructive logic
9+- Curry-Howard correspondence
10+- Definitional and propositional equalities
11+- Axiomatic and constructive approaches
12+
13+Propositions and Judgments
14+==========================
15+
16+Propositions are the subject of our proofs, before the proof then we can't formally say if they are true or not. If the proof is successful then the result is a 'judgment'.
17+For instance, if the ``proposition`` is,
18+
19++-------+
20+| 1+1=2 |
21++-------+
22+
23+When we prove it, the ``judgment`` is,
24+
25++------------+
26+| 1+1=2 true |
27++------------+
28+
29+Or if the ``proposition`` is,
30+
31++-------+
32+| 1+1=3 |
33++-------+
34+
35+Obviously we can't prove it is true, but it is still a valid proposition and perhaps we can prove it is false so the ``judgment`` is,
36+
37++-------------+
38+| 1+1=3 false |
39++-------------+
40+
41+This may seem a bit pedantic but it is important to be careful, in mathematics not every proposition is true or false for instance, a proposition may be unproven or even unprovable.
42+
43+So the logic here is different from the logic that comes from boolean algebra. In that case what is not true is false and what is not false is true. The logic we are using here does not have this 'law of excluded middle' so we have to be careful not to use it.
44+
45+A false proposition is taken to be a contradiction and if we have a contradiction then we can prove anything, so we need to avoid this. Some languages, used in proof assistants, prevent contradictions but such languages cannot be Turing complete, so Idris does not prevent contradictions.
46+
47+The logic we are using is called constructive (or sometimes intuitional) because we are constructing a 'database' of judgments.
48+
49+There are also many other types of logic, another important type of logic for Idris programmers is '``linear logic``' but that's not discussed on this page.
50+
51+Curry-Howard correspondence
52+===========================
53+
54+So how to we relate these proofs to Idris programs? It turns out that there is a correspondence between constructive logic and type theory. They are the same structure and we can switch backward and forward between the two notations because they are the same thing.
55+
56+The way that this works is that a proposition is a type so this,
57+
58+.. code-block:: idris
59+
60+ Idris> 1+1=2
61+ 2 = 2 : Type
62+
63+is a proposition and it is also a type. This is built into Idris so when an '=' equals sign appears in a function type an equality type is generated. The following will also produce an equality type:
64+
65+
66+.. code-block:: idris
67+
68+ Idris> 1+1=3
69+ 2 = 3 : Type
70+
71+Both of these are valid propositions so both are valid equality types. But how do we represent true judgment, that is, how do we denote 1+1=2 is true but not 1+1=3.
72+A type that is true is inhabited, that is, it can be constructed. An equality type has only one constructor 'Refl' so a proof of 1+1=2 is
73+
74+.. code-block:: idris
75+
76+ onePlusOne : 1+1=2
77+ onePlusOne = Refl
78+
79+So how can Refl, which is a constructor without any parameters, construct an equality type? If we type it on its own then it can't:
80+
81+.. code-block:: idris
82+
83+ Idris> Refl
84+ (input):Can't infer argument A to Refl, Can't infer argument x to Refl
85+
86+So it must pattern match on its return type:
87+
88+.. code-block:: idris
89+
90+ Idris> the (1=1) Refl
91+ Refl : 1 = 1
92+
93+So now that we can represent propositions as types other aspects of propositional logic can also be translated to types as follows:
94+
95++----------+-------------------+--------------------------+
96+| | propositions | example of possible type |
97++----------+-------------------+--------------------------+
98+| A | x=y | |
99++----------+-------------------+--------------------------+
100+| B | y=z | |
101++----------+-------------------+--------------------------+
102+| and | A /\\ B | ``Pair(x=y,y=z)`` |
103++----------+-------------------+--------------------------+
104+| or | A \\/ B | ``Either(x=y,y=z)`` |
105++----------+-------------------+--------------------------+
106+| implies | A -> B | ``(x=y) -> (y=x)`` |
107++----------+-------------------+--------------------------+
108+| for all | y=z | |
109++----------+-------------------+--------------------------+
110+| exists | y=z | |
111++----------+-------------------+--------------------------+
112+
113+
114+And (conjunction)
115+-----------------
116+
117+We can have a type which corresponds to conjunction:
118+
119+.. code-block:: idris
120+
121+ AndIntro : a -> b -> A a b
122+
123+There is a built in type called 'Pair'.
124+
125+Or (disjunction)
126+----------------
127+
128+We can have a type which corresponds to disjunction:
129+
130+.. code-block:: idris
131+
132+ data Or : Type -> Type -> Type where
133+ OrIntroLeft : a -> A a b
134+ OrIntroRight : b -> A a b
135+
136+There is a built in type called 'Either'.
137+
138+Definitional and Propositional Equalities
139+=========================================
140+
141+We have seen that we can 'prove' a type by finding a way to construct a term. In the case of equality types there is only one constructor which is 'Refl'.
142+We have also seen that each side of the equation does not have to be identical like '2=2'. It is enough that both sides are ``definitionaly equal`` like this:
143+
144+.. code-block:: idris
145+
146+ onePlusOne : 1+1=2
147+ onePlusOne = Refl
148+
149+So both sides of this equation nomalise to 2 and so Refl will type match and the proposition is proved.
150+
151+We don't have to stick to terms, can also use symbolic parameters so the following will compile:
152+
153+.. code-block:: idris
154+
155+ varIdentity : m = m
156+ varIdentity = Refl
157+
158+If a proposition/equality type is not definitionaly equal but is still true then it is ``propositionaly equal``. In this case we may still be able to prove it but some steps in the proof may require us to add something into the terms or at least to take some sideways steps to get to a proof.
159+
160+Especially when working with equalities containing variable terms (inside functions) it can be hard to know which equality types are definitially equal, in this example plusReducesL is '``definitially equal``' but plusReducesR is not (although it is '``propositionaly equal``'). The only difference between them is the order of the operands.
161+
162+.. code-block:: idris
163+
164+ plusReducesL : (n:Nat) -> plus Z n = n
165+ plusReducesL n = Refl
166+
167+ plusReducesR : (n:Nat) -> plus n Z = n
168+ plusReducesR n = Refl
169+
170+plusReducesR gives the following error:
171+
172+
173+.. code-block:: idris
174+
175+ - + Errors (1)
176+ `-- proof.idr line 6 col 17:
177+ When checking right hand side of plusReducesR with expected type
178+ plus n 0 = n
179+
180+ Type mismatch between
181+ n = n (Type of Refl)
182+ and
183+ plus n 0 = n (Expected type)
184+
185+ Specifically:
186+ Type mismatch between
187+ n
188+ and
189+ plus n 0
190+
191+So why is 'Refl' able to prove some equality types but not others?
192+
193+The first answer is that 'plus' is defined in such a way that it splits on its first argument so it is simple to prove when 0 is the first argument but not the second. So what is the general way to know if Refl will work?
194+
195+If an equality type can be proved/constructed by using Refl alone it is known as a ``definitional equality``. In order to be definitinally equal both sides of the equation must normalise to unique values. That is, each step in the proof must reduce the term so each step is effectively forced.
196+
197+So when we type 1+1 in Idris it is immediately converted to 2 because definitional equality is built in.
198+
199+.. code-block:: idris
200+
201+ Idris> 1+1
202+ 2 : Integer
203+
204+In the following pages we discuss how to resolve propositionaly equalies.
205+
206+Axiomatic and Constructive Approaches
207+=====================================
208+
209+How should we define types so that we can do proofs on them? In the natural numbers with the plus example we could have started by treating it as a group based on the plus operator. So we have axioms:
210+
211+- for all x,y : ``x+y=y+x``
212+- for all x: ``x + 0 = x = 0 + x``
213+- for all x,y,z: ``(x + y) + z = x + (x + z)``
214+
215+Then we can implement '+' so that it respects these axioms (presumably implemented in hardware).
216+
217+These are axioms, that is a propositions/types that are asserted to be true without proof. In Idris we can use the 'postulate' keyword
218+
219+
220+.. code-block:: idris
221+
222+ postulate commutePlus: (x:Nat) -> (y:Nat) -> plus x y = plus y x
223+
224+Alternatively we could define the natural numbers based on Zero and Successor. The axioms above then become derived rules and we also gain the ability to do inductive proofs.
225+
226+As we know, Idris uses both of these approaches with automatic coercion between them which gives the best of both worlds.
227+
228+So what can we learn from this to implement our own types:
229+
230+- Should we try to implement both approaches?
231+- Should we define our types by constructing up from primitive types?
232+
233+Proof theory affects these design decisions.

10−is generally not recommended to be used directly, but rather used as a
11−mechanism for building proof automation which is beyond the scope of this
12−tutorial. In this section, we briefly discus tactics.
7+:ref:`elaborator-reflection` is also used to convert high-level Idris code into
8+the core language and for customising the language. Here we show how to use it
9+to interactively construct proofs.
10+
11+The primary purpose of the elaboration mechanism is to elaborate Idris and so it
12+is not optimised to work as a proof assistant, however it can interactively
13+construct proofs as described on this page.
14+
15+Elab and Pruviloj Libraries
16+===========================
17+
18+Elaborator reflection is defined in ``prelude/Language/Reflection/Elab.idr``
19+and ``pruviloj`` is defined in ``Idris-dev/libs/pruviloj/``.
20+
21+``Elab`` defines the basics such as: ``solve``, ``attack``, ``intro``, ``compute``,
22+``rewriteWith`` and others.
23+``pruviloj`` defines some more advanced derived commands such as:
24+``reflexivity`` and others.
25+
26+To use ``pruviloj`` call Idris with the ``-p pruviloj`` option and add:
27+
28+.. code-block:: idris
29+
30+ import Pruviloj
31+ import Pruviloj.Induction
32+
33+to the top of your file.
34+
35+It is useful to get the docs at the REPL by using the ``:doc`` command, and
36+search the docstrings using ``:apropos``. So to introduce the functions from
37+``Elab`` and ``Pruviloj``, that we will need for the following example, here are
38+their docstrings:
39+
40+.. code-block:: idris
41+
42+ *plusReducesZ> :doc solve
43+ Language.Reflection.Elab.Tactics.solve : Elab ()
44+ Substitute a guess into a hole.
45+
46+.. code-block:: idris
47+
48+ *plusReducesZ> :doc attack
49+ Language.Reflection.Elab.Tactics.attack : Elab ()
50+ Convert a hole to make it suitable for bindings - that is, transform
51+ it such that it has the form ?h : t . h as opposed to ?h : t . f h.
52+
53+ The binding tactics require that a hole be directly under its binding,
54+ or else the scopes of the generated terms won't make sense. This
55+ tactic creates a new hole of the proper form, and points the old hole
56+ at it.
57+
58+.. code-block:: idris
59+
60+ *plusReducesZ> :doc intro
61+ Language.Reflection.Elab.Tactics.intro : (n : TTName) -> Elab ()
62+ Introduce a lambda binding around the current hole and focus on the
63+ body. Requires that the hole be in binding form (use attack).
64+ Arguments:
65+ n : TTName -- the name to use for the argument
66+
67+.. code-block:: idris
68+
69+ *plusReducesZ> :doc compute
70+ Language.Reflection.Elab.Tactics.compute : Elab ()
71+ Normalise the goal.
72+
73+.. code-block:: idris
74+
75+ *plusReducesZ> :doc rewriteWith
76+ Language.Reflection.Elab.Tactics.rewriteWith : Raw -> Elab ()
77+ Attempt to rewrite the goal using an equality.
78+
79+ The tactic searches the goal for applicable subterms, and constructs a
80+ context for replace using them. In some cases, this is not possible,
81+ and replace must be called manually with an appropriate context.
82+
83+ Because this tactic internally introduces a let binding, it requires
84+ that the hole be immediately under its binder (use attack if it might
85+ not be).
86+
87+Here is the command from ``pruviloj`` that we will need for the example on
88+this page:
89+
90+.. code-block:: idris
91+
92+ *plusReducesZ> :doc reflexivity
93+ Pruviloj.Core.reflexivity : Elab ()
94+ A special-purpose tactic that attempts to solve a goal using Refl.
95+ This is useful for ensuring that goals in fact are trivial when
96+ developing or testing other tactics; otherwise, consider using search.

65−prompt we can enter tactics to direct the construction of the proof. In
66−this case, we can normalise the goal with the ``compute`` tactic:
152+This has been normalised to ``0 = 0`` so now we have to prove that ``0`` equals ``0``, which

75−Now we have to prove that ``Z`` equals ``Z``, which is easy to prove by
76−``Refl``. To apply a function, such as ``Refl``, we use ``refine`` which
77−introduces subgoals for each of the function’s explicit arguments
78−(``Refl`` has none):

88−to add the proof to the global context, and remove the hole from the

114187
115188In this case, the goal is a function type, using ``k`` (the argument
116189accessible by pattern matching) and ``ih`` — the local variable
117190containing the result of the recursive call. We can introduce these as
118−premises using the ``intro`` tactic twice (or ``intros``, which
119−introduces all arguments as premises). This gives:
191+assumptions using the ``intro`` tactic twice. The parameter is entered as
192+a constant of type ``TTName`` which is entered as a backtick with double
193+braces ```{{ih}}``. This gives:

210+
211+We know, from the type of ``ih``, that ``k = plus k 0``, so we would
212+like to use this knowledge to replace ``plus k 0`` in the goal with
213+``k``. We can achieve this with the ``rewriteWith`` tactic:

126− {hole2} : S k = plus (S k) Z

127218
128−Since plus is defined by recursion on its first argument, the term
129−``plus (S k) Z`` in the goal can be simplified, so we use ``compute``.
219+ ---------- Assumptions: ----------
220+ k : Nat
221+ ih : k = plus k 0
222+ ---------- Goal: ----------
223+ {hole_0} : S k = S k
224+
225+The ``rewriteWith`` tactic takes an equality proof as an argument, and tries
226+to rewrite the goal using that proof. The ``ih`` value is entered as a constant
227+of type ``TTName`` which is entered as a backtick with double braces ```{{ih}}`` but
228+``rewriteWith`` requires an expression of type ``Raw``, rather than just a name,
229+so the ``Var`` constructor is used to make a variable. Here, it results in an equality
230+which is trivially provable using ``reflexivity``:

2+DEPRECATED: Interactive Theorem Proving Using Old Tactics Code
3+**************************************************************
4+
5+.. warning::
6+ The interactive theorem-proving interface documented here has been
7+ deprecated in favor of :ref:`elaborator-reflection`.
8+
9+Idris also supports interactive theorem proving via tactics. This
10+is generally not recommended to be used directly, but rather used as a
11+mechanism for building proof automation which is beyond the scope of this
12+tutorial. In this section, we briefly discus tactics.
13+
14+One way to write proofs interactively is to write the general *structure* of
15+the proof, and use the interactive mode to complete the details.
16+Consider the following definition, proved in :ref:`sect-theorems`:
17+
18+.. code-block:: idris
19+
20+ plusReduces : (n:Nat) -> plus Z n = n
21+
22+We’ll be constructing the proof by *induction*, so we write the cases for ``Z``
23+and ``S``, with a recursive call in the ``S`` case giving the inductive
24+hypothesis, and insert *holes* for the rest of the definition:
25+
26+.. code-block:: idris
27+
28+ plusReducesZ' : (n:Nat) -> n = plus n Z
29+ plusReducesZ' Z = ?plusredZ_Z
30+ plusReducesZ' (S k) = let ih = plusReducesZ' k in
31+ ?plusredZ_S
32+
33+On running , two global names are created, ``plusredZ_Z`` and
34+``plusredZ_S``, with no definition. We can use the ``:m`` command at the
35+prompt to find out which holes are still to be solved (or, more
36+precisely, which functions exist but have no definitions), then the
37+``:t`` command to see their types:
38+
39+.. code-block:: idris
40+
41+ *theorems> :m
42+ Global holes:
43+ [plusredZ_S,plusredZ_Z]

50+ *theorems> :t plusredZ_S
51+ plusredZ_S : (k : Nat) -> (k = plus k Z) -> S k = plus (S k) Z
52+
53+The ``:p`` command enters interactive proof mode, which can be used to
54+complete the missing definitions.
55+
56+.. code-block:: idris
57+
58+ *theorems> :p plusredZ_Z
59+
60+ ---------------------------------- (plusredZ_Z) --------
61+ {hole0} : Z = plus Z Z
62+
63+This gives us a list of premises (above the line; there are none here)
64+and the current goal (below the line; named ``{hole0}`` here). At the
65+prompt we can enter tactics to direct the construction of the proof. In
66+this case, we can normalise the goal with the ``compute`` tactic:
67+
68+.. code-block:: idris
69+
70+ -plusredZ_Z> compute
71+
72+ ---------------------------------- (plusredZ_Z) --------
73+ {hole0} : Z = Z
74+
75+Now we have to prove that ``Z`` equals ``Z``, which is easy to prove by
76+``Refl``. To apply a function, such as ``Refl``, we use ``refine`` which
77+introduces subgoals for each of the function’s explicit arguments
78+(``Refl`` has none):
79+
80+.. code-block:: idris
81+
82+ -plusredZ_Z> refine Refl
83+ plusredZ_Z: no more goals
84+
85+Here, we could also have used the ``trivial`` tactic, which tries to
86+refine by ``Refl``, and if that fails, tries to refine by each name in
87+the local context. When a proof is complete, we use the ``qed`` tactic
88+to add the proof to the global context, and remove the hole from the
89+unsolved holes list. This also outputs a trace of the proof:

102+ [plusredZ_S]
103+
104+The ``:addproof`` command, at the interactive prompt, will add the proof
105+to the source file (effectively in an appendix). Let us now prove the
106+other required lemma, ``plusredZ_S``:

111+
112+ ---------------------------------- (plusredZ_S) --------
113+ {hole0} : (k : Nat) -> (k = plus k Z) -> S k = plus (S k) Z
114+
115+In this case, the goal is a function type, using ``k`` (the argument
116+accessible by pattern matching) and ``ih`` — the local variable
117+containing the result of the recursive call. We can introduce these as
118+premises using the ``intro`` tactic twice (or ``intros``, which
119+introduces all arguments as premises). This gives:

124+ ih : k = plus k Z
125+ ---------------------------------- (plusredZ_S) --------
126+ {hole2} : S k = plus (S k) Z
127+
128+Since plus is defined by recursion on its first argument, the term
129+``plus (S k) Z`` in the goal can be simplified, so we use ``compute``.

135+ ---------------------------------- (plusredZ_S) --------

137+
138+We know, from the type of ``ih``, that ``k = plus k Z``, so we would
139+like to use this knowledge to replace ``plus k Z`` in the goal with
140+``k``. We can achieve this with the ``rewrite`` tactic:

148+ ---------------------------------- (plusredZ_S) --------
149+ {hole3} : S k = S k
150+
151+ -plusredZ_S>
152+
153+The ``rewrite`` tactic takes an equality proof as an argument, and tries
154+to rewrite the goal using that proof. Here, it results in an equality
155+which is trivially provable:
156+
157+.. code-block:: idris
158+

1+******************************
2+Proving Propositional Equality
3+******************************
4+
5+This page attempts to explain some of the techniques used in Idris to prove propositional equalities.
6+
7+We have seen that definitional equalities can be proved using ``Refl`` since they always normalise to unique values that can be compared directly.
8+
9+However with propositional equalities we are using symbolic variables they do not always normalise.
10+
11+So to take the previous example:
12+
13+.. code-block:: idris
14+
15+ plusReducesR : (n:Nat) -> plus n Z = n
16+
17+In this case ``plus n Z`` does not normalise to ``n``. Even though both sides are equal we cannot pattern match ``Refl``.
18+
19+If the pattern match cannot match for all ``n`` then the way around this is to separately match all possible values of ``n``. In the case of natural numbers we do this by induction.
20+
21+So here:
22+
23+.. code-block:: idris
24+
25+ plusReducesR : n = plus n 0
26+ plusReducesR {n = Z} = Refl
27+ plusReducesR {n = (S k)} = let rec = plus_commutes_Z {n=k} in
28+ rewrite rec in Refl
29+
30+we don't call ``Refl`` to match on ``n = plus n 0`` forall ``n`` we call it for every number separately. So, in the second line, the pattern matcher knows to substitute ``Z`` for ``n`` in the type being matched. This uses ``rewrite`` which is explained below.
31+
32+Replace
33+=======
34+
35+This implements the *indiscernability of identicals* principle, if two terms are equal then they have the same properties. In other words, if ``x=y``, then we can substitute ``y`` for ``x`` in any expression. In our proofs we can express this as:
36+
37+.. code-block:: idris
38+
39+ if x=y
40+ then P x = P y
41+
42+where ``P`` is a pure function representing the property. In the examples below ``P`` is an expression in some variable with a type like this: ``P: n -> Type``.
43+
44+So if ``n`` is a natural number variable then ``P`` could be something like ``2*n + 3``.
45+
46+To use this in our proofs there is the following function in the prelude:
47+
48+.. code-block:: idris
49+
50+ ||| Perform substitution in a term according to some equality.
51+ replace : {a:_} -> {x:_} -> {y:_} -> {P : a -> Type} -> x = y -> P x -> P y
52+ replace Refl prf = prf
53+
54+Removing the implicits, if we supply an equality ``x=y`` and a proof of a property of ``x`` (i.e. ``P x``) then we get a proof of a property of ``y`` (i.e. ``P y``)
55+
56+.. code-block:: idris
57+
58+ > :t replace
59+ replace : (x = y) -> P x -> P y
60+
61+So, in the following example, if we supply ``p1 x`` which is a proof that ``x=2`` and the equality ``x=y`` then we get a proof that ``y=2``.
62+
63+.. code-block:: idris
64+
65+ p1: Nat -> Type
66+ p1 n = (n=2)
67+
68+ testReplace: (x=y) -> (p1 x) -> (p1 y)
69+ testReplace a b = replace a b
70+
71+Rewrite
72+=======
73+
74+Similar to ``replace`` above but Idris provides a nicer syntax which makes ``rewrite`` easier to use in examples like ``plusReducesR`` above.
75+
76+.. code-block:: idris
77+
78+ rewrite__impl : (P : a -> Type) -> x = y -> P y -> P x
79+ rewrite__impl p Refl prf = prf
80+
81+The difference from ``replace`` above is nicer syntax and the property ``p1`` is explicitly supplied and it goes in the opposite direction (input and output reversed).
82+
83+Example: again we supply ``p1`` which is a proof that ``x=2`` and the equality ``x=y`` then we get a proof that ``y=2``.
84+
85+.. code-block:: idris
86+
87+ p1: Nat -> Type
88+ p1 x = (x=2)
89+
90+ testRewrite2: (x=y) -> (p1 y) -> (p1 x)
91+ testRewrite2 a b = rewrite a in b
92+
93+We can think of rewrite doing this:
94+
95+ * start with a equation ``x=y`` and a property ``P: x -> Type``;
96+ * search ``y`` in ``P``;
97+ * replace all occurrences of ``y`` with ``x`` in ``P``.
98+
99+That is, we are doing a substitution.
100+
101+Symmetry and Transitivity
102+=========================
103+
104+In addition to *reflexivity* equality also obeys *symmetry* and *transitivity* and these are also included in the prelude:
105+
106+.. code-block:: idris
107+
108+ ||| Symmetry of propositional equality
109+ sym : {left:a} -> {right:b} -> left = right -> right = left
110+ sym Refl = Refl
111+
112+ ||| Transitivity of propositional equality
113+ trans : {a:x} -> {b:y} -> {c:z} -> a = b -> b = c -> a = c
114+ trans Refl Refl = Refl
115+
116+Heterogeneous Equality
117+======================
118+
119+Also included in the prelude:
120+
121+.. code-block:: idris
122+
123+ ||| Explicit heterogeneous ("John Major") equality. Use this when Idris
124+ ||| incorrectly chooses homogeneous equality for `(=)`.
125+ ||| @ a the type of the left side
126+ ||| @ b the type of the right side
127+ ||| @ x the left side
128+ ||| @ y the right side
129+ (~=~) : (x : a) -> (y : b) -> Type
130+ (~=~) x y = (x = y)

314+
315+The FP heap is the primary heap. It may contain values of type ``CData``,
316+which are references to items in the C heap. A C heap item contains
317+a ``(void *)`` pointer and the corresponding finalizer. Once a C heap item
318+is no longer referenced from the FP heap, it is marked as unused and
319+the next GC sweep will call its finalizer and deallocate it.
320+
321+There is no Idris interface for ``CData`` other than its type and FFI.
322+
323+Usage from C code
324+~~~~~~~~~~~~~~~~~
325+
326+* Although not enforced in code, ``CData`` is meant to be opaque
327+ and non-RTS code (such as libraries or C bindings) should
328+ access only its ``(void *)`` field called ``data``.
329+
330+* Feel free to mutate both the pointer ``data`` (eg. after calling ``realloc``)
331+ and the memory it points to. However, keep in mind
332+ that this must not break Idris's referential transparency.
333+
334+* **WARNING!** If you call ``cdata_allocate`` or ``cdata_manage``,

4+Composing State Machines
5+************************
6+
7+In the previous section, we defined a ``DataStore`` interface and used it
8+to implement the following small program which allows a user to log in to
9+the store then display the store's contents;
10+
11+.. code-block:: idris
12+
13+ getData : (ConsoleIO m, DataStore m) => ST m () []
14+ getData = do st <- connect
15+ OK <- login st
16+ | BadPassword => do putStrLn "Failure"
17+ disconnect st
18+ secret <- readSecret st
19+ putStrLn ("Secret is: " ++ show secret)
20+ logout st
21+ disconnect st
22+
23+This function only uses one state, the store itself. Usually, though,
24+larger programs have lots of states, and might add, delete and update
25+states over the course of its execution. Here, for example, a useful
26+extension might be to loop forever, keeping count of the number of times
27+there was a login failure in a state.
28+
29+Furthermore, we may have *hierarchies* of state machines, in that one
30+state machine could be implemented by composing several others. For
31+example, we can have a state machine representing the state of a
32+graphics system, and use this to implement a *higher level* graphics API
33+such as turtle graphics, which uses the graphics system plus some additional
34+state for the turtle.
35+
36+In this section, we'll see how to work with multiple states, and how to
37+compose state machines to make higher level state machines. We'll begin by
38+seeing how to add a login failure counter to ``getData``.
39+
40+Working with multiple resources
41+===============================
42+
43+To see how to work with multiple resources, we'll modify ``getData`` so
44+that it loops, and counts the total number of times the user fails to
45+log in. For example, if we write a ``main`` program which initialises the
46+count to zero, a session might run as follows:
47+
48+.. code::
49+
50+ *LoginCount> :exec main
51+ Enter password: Mornington Crescent
52+ Secret is: "Secret Data"
53+ Enter password: Dollis Hill
54+ Failure
55+ Number of failures: 1
56+ Enter password: Mornington Crescent
57+ Secret is: "Secret Data"
58+ Enter password: Codfanglers
59+ Failure
60+ Number of failures: 2
61+ ...
62+
63+We'll start by adding a state resource to ``getData`` to keep track of the
64+number of failures:
65+
66+.. code-block:: idris
67+
68+ getData : (ConsoleIO m, DataStore m) =>
69+ (failcount : Var) -> ST m () [failcount ::: State Integer]
70+
71+.. topic:: Type checking ``getData``
72+
73+ If you're following along in the code, you'll find that ``getData``
74+ no longer compiles when you update this type. That is to be expected!
75+ For the moment, comment out the definition of ``getData``. We'll come back
76+ to it shortly.
77+
78+Then, we can create a ``main`` program which initialises the state to ``0``
79+and invokes ``getData``, as follows:
80+
81+.. code-block:: idris
82+
83+ main : IO ()
84+ main = run (do fc <- new 0
85+ getData fc
86+ delete fc)
87+
88+We'll start our implementation of ``getData`` just by adding the new
89+argument for the failure count:
90+
91+.. code-block:: idris
92+
93+ getData : (ConsoleIO m, DataStore m) =>
94+ (failcount : Var) -> ST m () [failcount ::: State Integer]
95+ getData failcount
96+ = do st <- connect
97+ OK <- login st
98+ | BadPassword => do putStrLn "Failure"
99+ disconnect st
100+ secret <- readSecret st
101+ putStrLn ("Secret is: " ++ show secret)
102+ logout st
103+ disconnect st
104+
105+Unfortunately, this doesn't type check, because we have the wrong resources
106+for calling ``connect``. The error messages shows how the resources don't
107+match:
108+
109+.. code-block:: idris
110+
111+ When checking an application of function Control.ST.>>=:
112+ Error in state transition:
113+ Operation has preconditions: []
114+ States here are: [failcount ::: State Integer]
115+ Operation has postconditions: \result => [result ::: Store LoggedOut] ++ []
116+ Required result states here are: st2_fn
117+
118+In other words, ``connect`` requires that there are *no* resources on
119+entry, but we have *one*, the failure count!
120+This shouldn't be a problem, though: the required resources are a *subset* of
121+the resources we have, after all, and the additional resources (here, the
122+failure count) are not relevant to ``connect``. What we need, therefore,
123+is a way to temporarily *hide* the additional resource.
124+
125+We can achieve this with the ``call`` function:
126+
127+.. code-block:: idris
128+
129+ getData : (ConsoleIO m, DataStore m) =>
130+ (failcount : Var) -> ST m () [failcount ::: State Integer]
131+ getData failcount
132+ = do st <- call connect
133+ ?whatNow
134+
135+Here we've left a hole for the rest of ``getData`` so that you can see the
136+effect of ``call``. It has removed the unnecessary parts of the resource
137+list for calling ``connect``, then reinstated them on return. The type of
138+``whatNow`` therefore shows that we've added a new resource ``st``, and still
139+have ``failcount`` available:
140+
141+.. code-block:: idris
142+
143+ failcount : Var
144+ m : Type -> Type
145+ constraint : ConsoleIO m
146+ constraint1 : DataStore m
147+ st : Var
148+ --------------------------------------
149+ whatNow : STrans m () [failcount ::: State Integer, st ::: Store LoggedOut]
150+ (\result => [failcount ::: State Integer])
151+
152+By the end of the function, ``whatNow`` says that we need to have finished with
153+``st``, but still have ``failcount`` available. We can complete ``getData``
154+so that it works with an additional state resource by adding ``call`` whenever
155+we invoke one of the operations on the data store, to reduce the list of
156+resources:
157+
158+.. code-block:: idris
159+
160+ getData : (ConsoleIO m, DataStore m) =>
161+ (failcount : Var) -> ST m () [failcount ::: State Integer]
162+ getData failcount
163+ = do st <- call connect
164+ OK <- call $ login st
165+ | BadPassword => do putStrLn "Failure"
166+ call $ disconnect st
167+ secret <- call $ readSecret st
168+ putStrLn ("Secret is: " ++ show secret)
169+ call $ logout st
170+ call $ disconnect st
171+
172+This is a little noisy, and in fact we can remove the need for it by
173+making ``call`` implicit. By default, you need to add the ``call`` explicitly,
174+but if you import ``Control.ST.ImplicitCall``, Idris will insert ``call``
175+where it is necessary.
176+
177+.. code-block:: idris
178+
179+ import Control.ST.ImplicitCall
180+
181+It's now possible to write ``getData`` exactly as before:
182+
183+.. code-block:: idris
184+
185+ getData : (ConsoleIO m, DataStore m) =>
186+ (failcount : Var) -> ST m () [failcount ::: State Integer]
187+ getData failcount
188+ = do st <- connect
189+ OK <- login st
190+ | BadPassword => do putStrLn "Failure"
191+ disconnect st
192+ secret <- readSecret st
193+ putStrLn ("Secret is: " ++ show secret)
194+ logout st
195+ disconnect st
196+
197+There is a trade off here: if you import ``Control.ST.ImplicitCall`` then
198+functions which use multiple resources are much easier to read, because the
199+noise of ``call`` has gone. On the other hand, Idris has to work a little
200+harder to type check your functions, and as a result it can take slightly
201+longer, and the error messages can be less helpful.
202+
203+It is instructive to see the type of ``call``:
204+
205+.. code-block:: idris
206+
207+ call : STrans m t sub new_f -> {auto res_prf : SubRes sub old} ->
208+ STrans m t old (\res => updateWith (new_f res) old res_prf)
209+
210+The function being called has a list of resources ``sub``, and
211+there is an implicit proof, ``SubRes sub old`` that the resource list in
212+the function being called is a subset of the overall resource list. The
213+ordering of resources is allowed to change, although resources which
214+appear in ``old`` can't appear in the ``sub`` list more than once (you will
215+get a type error if you try this).
216+
217+The function ``updateWith`` takes the *output* resources of the
218+called function, and updates them in the current resource list. It makes
219+an effort to preserve ordering as far as possible, although this isn't
220+always possible if the called function does some complicated resource
221+manipulation.
222+
223+.. topic:: Newly created resources in called functions
224+
225+ If the called function creates any new resources, these will typically
226+ appear at the *end* of the resource list, due to the way ``updateWith``
227+ works. You can see this in the type of ``whatNow`` in our incomplete
228+ definition of ``getData`` above.
229+
230+Finally, we can update ``getData`` so that it loops, and keeps
231+``failCount`` updated as necessary:
232+
233+.. code-block:: idris
234+
235+ getData : (ConsoleIO m, DataStore m) =>
236+ (failcount : Var) -> ST m () [failcount ::: State Integer]
237+ getData failcount
238+ = do st <- call connect
239+ OK <- login st
240+ | BadPassword => do putStrLn "Failure"
241+ fc <- read failcount
242+ write failcount (fc + 1)
243+ putStrLn ("Number of failures: " ++ show (fc + 1))
244+ disconnect st
245+ getData failcount
246+ secret <- readSecret st
247+ putStrLn ("Secret is: " ++ show secret)
248+ logout st
249+ disconnect st
250+ getData failcount
251+
252+Note that here, we're connecting and disconnecting on every iteration.
253+Another way to implement this would be to ``connect`` first, then call
254+``getData``, and implement ``getData`` as follows:
255+
256+.. code-block:: idris
257+
258+ getData : (ConsoleIO m, DataStore m) =>
259+ (st, failcount : Var) -> ST m () [st ::: Store {m} LoggedOut, failcount ::: State Integer]
260+ getData st failcount
261+ = do OK <- login st
262+ | BadPassword => do putStrLn "Failure"
263+ fc <- read failcount
264+ write failcount (fc + 1)
265+ putStrLn ("Number of failures: " ++ show (fc + 1))
266+ getData st failcount
267+ secret <- readSecret st
268+ putStrLn ("Secret is: " ++ show secret)
269+ logout st
270+ getData st failcount
271+
272+It is important to add the explicit ``{m}`` in the type of ``Store {m}
273+LoggedOut`` for ``st``, because this gives Idris enough information to know
274+which implementation of ``DataStore`` to use to find the appropriate
275+implementation for ``Store``. Otherwise, if we only write ``Store LoggedOut``,
276+there's no way to know that the ``Store`` is linked with the computation
277+context ``m``.
278+
279+We can then ``connect`` and ``disconnect`` only once, in ``main``:
280+
281+.. code-block:: idris
282+
283+ main : IO ()
284+ main = run (do fc <- new 0
285+ st <- connect
286+ getData st fc
287+ disconnect st
288+ delete fc)
289+
290+By using ``call``, and importing ``Control.ST.ImplicitCall``, we can
291+write programs which use multiple resources, and reduce the list of
292+resources as necessary when calling functions which only use a subset of
293+the overall resources.
294+
295+Composite resources: Hierarchies of state machines
296+==================================================
297+
298+We've now seen how to use multiple resources in one function, which is
299+necessary for any realistic program which manipulates state. We can think
300+of this as "horizontal" composition: using multiple resources at once.
301+We'll often also need "vertical" composition: implementing one resource
302+in terms of one or more other resources.
303+
304+We'll see an example of this in this section. First, we'll implement a
305+small API for graphics, in an interface ``Draw``, supporting:
306+
307+* Opening a window, creating a double-buffered surface to draw on
308+* Drawing lines and rectangles onto a surface
309+* "Flipping" buffers, displaying the surface we've just drawn onto in
310+ the window
311+* Closing a window
312+
313+Then, we'll use this API to implement a higher level API for turtle graphics,
314+in an ``interface``.
315+This will require not only the ``Draw`` interface, but also a representation
316+of the turtle state (location, direction and pen colour).
317+
318+.. topic:: SDL bindings
319+
320+ For the examples in this section, you'll need to install the
321+ (very basic!) SDL bindings for Idris, available from
322+ https://github.com/edwinb/SDL-idris. These bindings implement a small
323+ subset of the SDL API, and are for illustrative purposes only.
324+ Nevertheless, they are enough to implement small graphical programs
325+ and demonstrate the concepts of this section.
326+
327+ Once you've installed this package, you can start Idris with the
328+ ``-p sdl`` flag, for the SDL bindings, and the ``-p contrib`` flag,
329+ for the ``Control.ST`` library.
330+
331+The ``Draw`` interface
332+----------------------
333+
334+We're going to use the Idris SDL bindings for this API, so you'll need
335+to import ``Graphics.SDL`` once you've installed the bindings.
336+We'll start by defining the ``Draw`` interface, which includes a data type
337+representing a surface on which we'll draw lines and rectangles:
338+
339+.. code-block:: idris
340+
341+ interface Draw (m : Type -> Type) where
342+ Surface : Type
343+
344+We'll need to be able to create a new ``Surface`` by opening a window:
345+
346+.. code-block:: idris
347+
348+ initWindow : Int -> Int -> ST m Var [add Surface]
349+
350+However, this isn't quite right. It's possible that opening a window
351+will fail, for example if our program is running in a terminal without
352+a windowing system available. So, somehow, ``initWindow`` needs to cope
353+with the possibility of failure. We can do this by returning a
354+``Maybe Var``, rather than a ``Var``, and only adding the ``Surface``
355+on success:
356+
357+.. code-block:: idris
358+
359+ initWindow : Int -> Int -> ST m (Maybe Var) [addIfJust Surface]
360+
361+This uses a type level function ``addIfJust``, defined in ``Control.ST``
362+which returns an ``Action`` that only adds a resource if the operation
363+succeeds (that is, returns a result of the form ``Just val``.
364+
365+.. topic:: ``addIfJust`` and ``addIfRight``
366+
367+ ``Control.ST`` defines functions for constructing new resources if an
368+ operation succeeds. As well as ``addIfJust``, which adds a resource if
369+ an operation returns ``Just ty``, there's also ``addIfRight``:
370+
371+ .. code-block:: idris
372+
373+ addIfJust : Type -> Action (Maybe Var)
374+ addIfRight : Type -> Action (Either a Var)
375+
376+ Each of these is implemented in terms of the following primitive action
377+ ``Add``, which takes a function to construct a resource list from the result
378+ of an operation:
379+
380+ .. code-block:: idris
381+
382+ Add : (ty -> Resources) -> Action ty
383+
384+ Using this, you can create your own actions to add resources
385+ based on the result of an operation, if required. For example,
386+ ``addIfJust`` is implemented as follows:
387+
388+ .. code-block:: idris
389+
390+ addIfJust : Type -> Action (Maybe Var)
391+ addIfJust ty = Add (maybe [] (\var => [var ::: ty]))
392+
393+If we create windows, we'll also need to be able to delete them:
394+
395+.. code-block:: idris
396+
397+ closeWindow : (win : Var) -> ST m () [remove win Surface]
398+
399+We'll also need to respond to events such as keypresses and mouse clicks.
400+The ``Graphics.SDL`` library provides an ``Event`` type for this, and
401+we can ``poll`` for events which returns the last event which occurred,
402+if any:
403+
404+.. code-block:: idris
405+
406+ poll : ST m (Maybe Event) []
407+
408+The remaining methods of ``Draw`` are ``flip``, which flips the buffers
409+displaying everything that we've drawn since the previous ``flip``, and
410+two methods for drawing: ``filledRectangle`` and ``drawLine``.
411+
412+.. code-block:: idris
413+
414+ flip : (win : Var) -> ST m () [win ::: Surface]
415+ filledRectangle : (win : Var) -> (Int, Int) -> (Int, Int) -> Col -> ST m () [win ::: Surface]
416+ drawLine : (win : Var) -> (Int, Int) -> (Int, Int) -> Col -> ST m () [win ::: Surface]
417+
418+We define colours as follows, as four components (red, green, blue, alpha):
419+
420+.. code-block:: idris
421+
422+ data Col = MkCol Int Int Int Int
423+
424+ black : Col
425+ black = MkCol 0 0 0 255
426+
427+ red : Col
428+ red = MkCol 255 0 0 255
429+
430+ green : Col
431+ green = MkCol 0 255 0 255
432+
433+ -- Also blue, yellow, magenta, cyan, white, similarly...
434+
435+If you import ``Graphics.SDL``, you can implement the ``Draw`` interface
436+using the SDL bindings as follows:
437+
438+.. code-block:: idris
439+
440+ implementation Draw IO where
441+ Surface = State SDLSurface
442+
443+ initWindow x y = do Just srf <- lift (startSDL x y)
444+ | pure Nothing
445+ var <- new srf
446+ pure (Just var)
447+
448+ closeWindow win = do lift endSDL
449+ delete win
450+
451+ flip win = do srf <- read win
452+ lift (flipBuffers srf)
453+ poll = lift pollEvent
454+
455+ filledRectangle win (x, y) (ex, ey) (MkCol r g b a)
456+ = do srf <- read win
457+ lift $ filledRect srf x y ex ey r g b a
458+ drawLine win (x, y) (ex, ey) (MkCol r g b a)
459+ = do srf <- read win
460+ lift $ drawLine srf x y ex ey r g b a
461+
462+In this implementation, we've used ``startSDL`` to initialise a window, which,
463+returns ``Nothing`` if it fails. Since the type of ``initWindow`` states that
464+it adds a resource when it returns a value of the form ``Just val``, we
465+add the surface returned by ``startSDL`` on success, and nothing on
466+failure. We can only successfully initialise if ``startDSL`` succeeds.
467+
468+Now that we have an implementation of ``Draw``, we can try writing some
469+functions for drawing into a window and execute them via the SDL bindings.
470+For example, assuming we have a surface ``win`` to draw onto, we can write a
471+``render`` function as follows which draws a line onto a black background:
472+
473+.. code-block:: idris
474+
475+ render : Draw m => (win : Var) -> ST m () [win ::: Surface {m}]
476+ render win = do filledRectangle win (0,0) (640,480) black
477+ drawLine win (100,100) (200,200) red
478+ flip win
479+
480+The ``flip win`` at the end is necessary because the drawing primitives
481+are double buffered, to prevent flicker. We draw onto one buffer, off-screen,
482+and display the other. When we call ``flip``, it displays the off-screen
483+buffer, and creates a new off-screen buffer for drawing the next frame.
484+
485+To include this in a program, we'll write a main loop which renders our
486+image and waits for an event to indicate the user wants to close the
487+application:
488+
489+.. code-block:: idris
490+
491+ loop : Draw m => (win : Var) -> ST m () [win ::: Surface {m}]
492+ loop win = do render win
493+ Just AppQuit <- poll
494+ | _ => loop win
495+ pure ()
496+
497+Finally, we can create a main program which initialises a window, if
498+possible, then runs the main loop:
499+
500+.. code-block:: idris
501+
502+ drawMain : (ConsoleIO m, Draw m) => ST m () []
503+ drawMain = do Just win <- initWindow 640 480
504+ | Nothing => putStrLn "Can't open window"
505+ loop win
506+ closeWindow win
507+
508+We can try this at the REPL using ``run``:
509+
510+.. code::
511+
512+ *Draw> :exec run drawMain
513+
514+A higher level interface: ``TurtleGraphics``
515+--------------------------------------------
516+
517+Turtle graphics involves a "turtle" moving around the screen, drawing a line as
518+it moves with a "pen". A turtle has attributes describing its location, the
519+direction it's facing, and the current pen colour. There are commands for
520+moving the turtle forwards, turning through an angle, and changing the
521+pen colour, among other things. One possible interface would be the
522+following:
523+
524+.. code-block:: idris
525+
526+ interface TurtleGraphics (m : Type -> Type) where
527+ Turtle : Type
528+
529+ start : Int -> Int -> ST m (Maybe Var) [addIfJust Turtle]
530+ end : (t : Var) -> ST m () [Remove t Turtle]
531+
532+ fd : (t : Var) -> Int -> ST m () [t ::: Turtle]
533+ rt : (t : Var) -> Int -> ST m () [t ::: Turtle]
534+
535+ penup : (t : Var) -> ST m () [t ::: Turtle]
536+ pendown : (t : Var) -> ST m () [t ::: Turtle]
537+ col : (t : Var) -> Col -> ST m () [t ::: Turtle]
538+
539+ render : (t : Var) -> ST m () [t ::: Turtle]
540+
541+Like ``Draw``, we have a command for initialising the turtle (here called
542+``start``) which might fail if it can't create a surface for the turtle to
543+draw on. There is also a ``render`` method, which is intended to render the
544+picture drawn so far in a window. One possible program with this interface
545+is the following, with draws a colourful square:
546+
547+.. code-block:: idris
548+
549+ turtle : (ConsoleIO m, TurtleGraphics m) => ST m () []
550+ turtle = with ST do
551+ Just t <- start 640 480
552+ | Nothing => putStr "Can't make turtle\n"
553+ col t yellow
554+ fd t 100; rt t 90
555+ col t green
556+ fd t 100; rt t 90
557+ col t red
558+ fd t 100; rt t 90
559+ col t blue
560+ fd t 100; rt t 90
561+ render t
562+ end t
563+
564+.. topic:: ``with ST do``
565+
566+ The purpose of ``with ST do`` in ``turtle`` is to disambiguate ``(>>=)``,
567+ which could be either the version from the ``Monad`` interface, or the
568+ version from ``ST``. Idris can work this out itself, but it takes time to
569+ try all of the possibilities, so the ``with`` clause can
570+ speed up type checking.
571+
572+To implement the interface, we could try using ``Surface`` to represent
573+the surface for the turtle to draw on:
574+
575+.. code-block:: idris
576+
577+ implementation Draw m => TurtleGraphics m where
578+ Turtle = Surface {m}
579+
580+Knowing that a ``Turtle`` is represented as a ``Surface``, we can use the
581+methods provided by ``Draw`` to implement the turtle. Unfortunately, though,
582+this isn't quite enough. We need to store more information: in particular, the
583+turtle has several attributes which we need to store somewhere.
584+So, not only do we need to represent the turtle as a ``Surface``, we need
585+to store some additional state. We can achieve this using a *composite*
586+resource.
587+
588+Introducing composite resources
589+-------------------------------
590+
591+A *composite* resource is built up from a list of other resources, and
592+is implemented using the following type, defined by ``Control.ST``:
593+
594+.. code-block:: idris
595+
596+ data Composite : List Type -> Type
597+
598+If we have a composite resource, we can split it into its constituent
599+resources, and create new variables for each of those resources, using
600+the *split* function. For example:
601+
602+.. code-block:: idris
603+
604+ splitComp : (comp : Var) -> ST m () [comp ::: Composite [State Int, State String]]
605+ splitComp comp = do [int, str] <- split comp
606+ ?whatNow
607+
608+The call ``split comp`` extracts the ``State Int`` and ``State String`` from
609+the composite resource ``comp``, and stores them in the variables ``int``
610+and ``str`` respectively. If we check the type of ``whatNow``, we'll see
611+how this has affected the resource list:
612+
613+.. code-block:: idris
614+
615+ int : Var
616+ str : Var
617+ comp : Var
618+ m : Type -> Type
619+ --------------------------------------
620+ whatNow : STrans m () [int ::: State Int, str ::: State String, comp ::: State ()]
621+ (\result => [comp ::: Composite [State Int, State String]])
622+
623+So, we have two new resources ``int`` and ``str``, and the type of
624+``comp`` has been updated to the unit type, so currently holds no data.
625+This is to be expected: we've just extracted the data into individual
626+resources after all.
627+
628+Now that we've extracted the individual resources, we can manipulate them
629+directly (say, incrementing the ``Int`` and adding a newline to the
630+``String``) then rebuild the composite resource using ``combine``:
631+
632+.. code-block:: idris
633+
634+ splitComp : (comp : Var) ->
635+ ST m () [comp ::: Composite [State Int, State String]]
636+ splitComp comp = do [int, str] <- split comp
637+ update int (+ 1)
638+ update str (++ "\n")
639+ combine comp [int, str]
640+ ?whatNow
641+
642+As ever, we can check the type of ``whatNow`` to see the effect of
643+``combine``:
644+
645+.. code-block:: idris
646+
647+ comp : Var
648+ int : Var
649+ str : Var
650+ m : Type -> Type
651+ --------------------------------------
652+ whatNow : STrans m () [comp ::: Composite [State Int, State String]]
653+ (\result => [comp ::: Composite [State Int, State String]])
654+
655+The effect of ``combine``, therefore, is to take existing
656+resources and merge them into one composite resource. Before we run
657+``combine``, the target resource must exist (``comp`` here) and must be
658+of type ``State ()``.
659+
660+It is instructive to look at the types of ``split`` and ``combine`` to see
661+the requirements on resource lists they work with. The type of ``split``
662+is the following:
663+
664+.. code-block:: idris
665+
666+ split : (lbl : Var) -> {auto prf : InState lbl (Composite vars) res} ->
667+ STrans m (VarList vars) res (\vs => mkRes vs ++ updateRes res prf (State ()))
668+
669+The implicit ``prf`` argument says that the ``lbl`` being split must be
670+a composite resource. It returns a variable list, built from the composite
671+resource, and the ``mkRes`` function makes a list of resources of the
672+appropriate types. Finally, ``updateRes`` updates the composite resource to
673+have the type ``State ()``.
674+
675+The ``combine`` function does the inverse:
676+
677+.. code-block:: idris
678+
679+ combine : (comp : Var) -> (vs : List Var) ->
680+ {auto prf : InState comp (State ()) res} ->
681+ {auto var_prf : VarsIn (comp :: vs) res} ->
682+ STrans m () res (const (combineVarsIn res var_prf))
683+
684+The implicit ``prf`` argument here ensures that the target resource ``comp``
685+has type ``State ()``. That is, we're not overwriting any other data.
686+The implicit ``var_prf`` argument is similar to ``SubRes`` in ``call``, and
687+ensures that every variable we're using to build the composite resource
688+really does exist in the current resource list.
689+
690+We can use composite resources to implement our higher level ``TurtleGraphics``
691+API in terms of ``Draw``, and any additional resources we need.
692+
693+Implementing ``Turtle``
694+-----------------------
695+
696+Now that we've seen how to build a new resource from an existing collection,
697+we can implement ``Turtle`` using a composite resource, containing the
698+``Surface`` to draw on, and individual states for the pen colour and the
699+pen location and direction. We also have a list of lines, which describes
700+what we'll draw onto the ``Surface`` when we call ``render``:
701+
702+.. code-block:: idris
703+
704+ Turtle = Composite [Surface {m}, -- surface to draw on
705+ State Col, -- pen colour
706+ State (Int, Int, Int, Bool), -- pen location/direction/d
707+ State (List Line)] -- lines to draw on render
708+
709+A ``Line`` is defined as a start location, and end location, and a colour:
710+
711+.. code-block:: idris
712+
713+ Line : Type
714+ Line = ((Int, Int), (Int, Int), Col)
715+
716+To implement ``start``, which creates a new ``Turtle`` (or returns ``Nothing``
717+if this is impossible), we begin by initialising the drawing surface then
718+all of the components of the state. Finally, we combine all of these
719+into a composite resource for the turtle:
720+
721+.. code-block:: idris
722+
723+ start x y = do Just srf <- initWindow x y
724+ | Nothing => pure Nothing
725+ col <- new white
726+ pos <- new (320, 200, 0, True)
727+ lines <- new []
728+ turtle <- new ()
729+ combine turtle [srf, col, pos, lines]
730+ pure (Just turtle)
731+
732+To implement ``end``, which needs to dispose of the turtle,
733+we deconstruct the composite resource, close the window,
734+then remove each individual resource. Remember that we can only ``delete``
735+a ``State``, so we need to ``split`` the composite resource, close the
736+drawing surface cleanly with ``closeWindow``, then ``delete`` the states:
737+
738+.. code-block:: idris
739+
740+ end t = do [srf, col, pos, lines] <- split t
741+ closeWindow srf; delete col; delete pos; delete lines; delete t
742+
743+For the other methods, we need to ``split`` the resource to get each
744+component, and ``combine`` into a composite resource when we're done.
745+As an example, here's ``penup``:
746+
747+.. code-block:: idris
748+
749+ penup t = do [srf, col, pos, lines] <- split t -- Split the composite resource
750+ (x, y, d, _) <- read pos -- Deconstruct the pen position
751+ write pos (x, y, d, False) -- Set the pen down flag to False
752+ combine t [srf, col, pos, lines] -- Recombine the components
753+
754+The remaining operations on the turtle follow a similar pattern. See
755+``samples/ST/Graphics/Turtle.idr`` in the Idris distribution for the full
756+details. It remains to render the image created by the turtle:
757+
758+.. code-block:: idris
759+
760+ render t = do [srf, col, pos, lines] <- split t -- Split the composite resource
761+ filledRectangle srf (0, 0) (640, 480) black -- Draw a background
762+ drawAll srf !(read lines) -- Render the lines drawn by the turtle
763+ flip srf -- Flip the buffers to display the image
764+ combine t [srf, col, pos, lines]
765+ Just ev <- poll
766+ | Nothing => render t -- Keep going until a key is pressed
767+ case ev of
768+ KeyUp _ => pure () -- Key pressed, so quit
769+ _ => render t
770+ where drawAll : (srf : Var) -> List Line -> ST m () [srf ::: Surface {m}]
771+ drawAll srf [] = pure ()
772+ drawAll srf ((start, end, col) :: xs)
773+ = do drawLine srf start end col -- Draw a line in the appropriate colour
774+ drawAll srf xs

3+***********************************
4+Example: Network Socket Programming
5+***********************************
6+
7+The POSIX sockets API supports communication between processes across a
8+network. A *socket* represents an endpoint of a network communication, and can be
9+in one of several states:
10+
11+* ``Ready``, the initial state
12+* ``Bound``, meaning that it has been bound to an address ready for incoming
13+ connections
14+* ``Listening``, meaning that it is listening for incoming connections
15+* ``Open``, meaning that it is ready for sending and receiving data;
16+* ``Closed``, meaning that it is no longer active.
17+
18+The following diagram shows how the operations provided by the API modify the
19+state, where ``Ready`` is the initial state:
20+
21+|netstate|
22+
23+If a connection is ``Open``, then we can also ``send`` messages to the
24+other end of the connection, and ``recv`` messages from it.
25+
26+The ``contrib`` package provides a module ``Network.Socket`` which
27+provides primitives for creating sockets and sending and receiving
28+messages. It includes the following functions:
29+
30+.. code-block:: idris
31+
32+ bind : (sock : Socket) -> (addr : Maybe SocketAddress) -> (port : Port) -> IO Int
33+ connect : (sock : Socket) -> (addr : SocketAddress) -> (port : Port) -> IO ResultCode
34+ listen : (sock : Socket) -> IO Int
35+ accept : (sock : Socket) -> IO (Either SocketError (Socket, SocketAddress))
36+ send : (sock : Socket) -> (msg : String) -> IO (Either SocketError ResultCode)
37+ recv : (sock : Socket) -> (len : ByteLength) -> IO (Either SocketError (String, ResultCode))
38+ close : Socket -> IO ()
39+
40+These functions cover the state transitions in the diagram above, but
41+none of them explain how the operations affect the state! It's perfectly
42+possible, for example, to try to send a message on a socket which is
43+not yet ready, or to try to receive a message after the socket is closed.
44+
45+Using ``ST``, we can provide a better API which explains exactly how
46+each operation affects the state of a connection. In this section, we'll
47+define a sockets API, then use it to implement an "echo" server which
48+responds to requests from a client by echoing back a single message sent
49+by the client.
50+
51+Defining a ``Sockets`` interface
52+================================
53+
54+Rather than using ``IO`` for low level socket programming, we'll implement
55+an interface using ``ST`` which describes precisely how each operation
56+affects the states of sockets, and describes when sockets are created
57+and removed. We'll begin by creating a type to describe the abstract state
58+of a socket:
59+
60+.. code-block:: idris
61+
62+ data SocketState = Ready | Bound | Listening | Open | Closed
63+
64+Then, we'll begin defining an interface, starting with a ``Sock`` type
65+for representing sockets, parameterised by their current state:
66+
67+.. code-block:: idris
68+
69+ interface Sockets (m : Type -> Type) where
70+ Sock : SocketState -> Type
71+
72+We create sockets using the ``socket`` method. The ``SocketType`` is defined
73+by the sockets library, and describes whether the socket is TCP, UDP,
74+or some other form. We'll use ``Stream`` for this throughout, which indicates a
75+TCP socket.
76+
77+.. code-block:: idris
78+
79+ socket : SocketType -> ST m (Either () Var) [addIfRight (Sock Ready)]
80+
81+Remember that ``addIfRight`` adds a resource if the result of the operation
82+is of the form ``Right val``. By convention in this interface, we'll use
83+``Either`` for operations which might fail, whether or not they might carry
84+any additional information about the error, so that we can consistently
85+use ``addIfRight`` and some other type level functions.
86+
87+To define a server, once we've created a socket, we need to ``bind`` it
88+to a port. We can do this with the ``bind`` method:
89+
90+.. code-block:: idris
91+
92+ bind : (sock : Var) -> (addr : Maybe SocketAddress) -> (port : Port) ->
93+ ST m (Either () ()) [sock ::: Sock Ready :-> (Sock Closed `or` Sock Bound)]
94+
95+Binding a socket might fail, for example if there is already a socket
96+bound to the given port, so again it returns a value of type ``Either``.
97+The action here uses a type level function ``or``, and says that:
98+
99+* If ``bind`` fails, the socket moves to the ``Sock Closed`` state
100+* If ``bind`` succeeds, the socket moves to the ``Sock Bound`` state, as
101+ shown in the diagram above
102+
103+``or`` is implemented as follows:
104+
105+.. code-block:: idris
106+
107+ or : a -> a -> Either b c -> a
108+ or x y = either (const x) (const y)
109+
110+So, the type of ``bind`` could equivalently be written as:
111+
112+.. code-block:: idris
113+
114+ bind : (sock : Var) -> (addr : Maybe SocketAddress) -> (port : Port) ->
115+ STrans m (Either () ()) [sock ::: Sock Ready]
116+ (either [sock ::: Sock Closed] [sock ::: Sock Bound])
117+
118+However, using ``or`` is much more concise than this, and attempts to
119+reflect the state transition diagram as directly as possible while still
120+capturing the possibility of failure.
121+
122+Once we've bound a socket to a port, we can start listening for connections
123+from clients:
124+
125+.. code-block:: idris
126+
127+ listen : (sock : Var) ->
128+ ST m (Either () ()) [sock ::: Sock Bound :-> (Sock Closed `or` Sock Listening)]
129+
130+A socket in the ``Listening`` state is ready to accept connections from
131+individual clients:
132+
133+.. code-block:: idris
134+
135+ accept : (sock : Var) ->
136+ ST m (Either () Var)
137+ [sock ::: Sock Listening, addIfRight (Sock Open)]
138+
139+If there is an incoming connection from a client, ``accept`` adds a *new*
140+resource to the end of the resource list (by convention, it's a good idea
141+to add resources to the end of the list, because this works more tidily
142+with ``updateWith``, as discussed in the previous section). So, we now
143+have *two* sockets: one continuing to listen for incoming connections,
144+and one ready for communication with the client.
145+
146+We also need methods for sending and receiving data on a socket:
147+
148+.. code-block:: idris
149+
150+ send : (sock : Var) -> String ->
151+ ST m (Either () ()) [sock ::: Sock Open :-> (Sock Closed `or` Sock Open)]
152+ recv : (sock : Var) ->
153+ ST m (Either () String) [sock ::: Sock Open :-> (Sock Closed `or` Sock Open)]
154+
155+Once we've finished communicating with another machine via a socket, we'll
156+want to ``close`` the connection and remove the socket:
157+
158+.. code-block:: idris
159+
160+ close : (sock : Var) ->
161+ {auto prf : CloseOK st} -> ST m () [sock ::: Sock st :-> Sock Closed]
162+ remove : (sock : Var) ->
163+ ST m () [Remove sock (Sock Closed)]
164+
165+We have a predicate ``CloseOK``, used by ``close`` in an implicit proof
166+argument, which describes when it is okay to close a socket:
167+
168+.. code-block:: idris
169+
170+ data CloseOK : SocketState -> Type where
171+ CloseOpen : CloseOK Open
172+ CloseListening : CloseOK Listening
173+
174+That is, we can close a socket which is ``Open``, talking to another machine,
175+which causes the communication to terminate. We can also close a socket which
176+is ``Listening`` for incoming connections, which causes the server to stop
177+accepting requests.
178+
179+In this section, we're implementing a server, but for completeness we may
180+also want a client to connect to a server on another machine. We can do
181+this with ``connect``:
182+
183+.. code-block:: idris
184+
185+ connect : (sock : Var) -> SocketAddress -> Port ->
186+ ST m (Either () ()) [sock ::: Sock Ready :-> (Sock Closed `or` Sock Open)]
187+
188+For reference, here is the complete interface:
189+
190+.. code-block:: idris
191+
192+ interface Sockets (m : Type -> Type) where
193+ Sock : SocketState -> Type
194+ socket : SocketType -> ST m (Either () Var) [addIfRight (Sock Ready)]
195+ bind : (sock : Var) -> (addr : Maybe SocketAddress) -> (port : Port) ->
196+ ST m (Either () ()) [sock ::: Sock Ready :-> (Sock Closed `or` Sock Bound)]
197+ listen : (sock : Var) ->
198+ ST m (Either () ()) [sock ::: Sock Bound :-> (Sock Closed `or` Sock Listening)]
199+ accept : (sock : Var) ->
200+ ST m (Either () Var) [sock ::: Sock Listening, addIfRight (Sock Open)]
201+ connect : (sock : Var) -> SocketAddress -> Port ->
202+ ST m (Either () ()) [sock ::: Sock Ready :-> (Sock Closed `or` Sock Open)]
203+ close : (sock : Var) -> {auto prf : CloseOK st} ->
204+ ST m () [sock ::: Sock st :-> Sock Closed]
205+ remove : (sock : Var) -> ST m () [Remove sock (Sock Closed)]
206+ send : (sock : Var) -> String ->
207+ ST m (Either () ()) [sock ::: Sock Open :-> (Sock Closed `or` Sock Open)]
208+ recv : (sock : Var) ->
209+ ST m (Either () String) [sock ::: Sock Open :-> (Sock Closed `or` Sock Open)]
210+
211+We'll see how to implement this shortly; mostly, the methods can be implemented
212+in ``IO`` by using the raw sockets API directly. First, though, we'll see
213+how to use the API to implement an "echo" server.
214+
215+Implementing an "Echo" server with ``Sockets``
216+==============================================
217+
218+At the top level, our echo server begins and ends with no resources available,
219+and uses the ``ConsoleIO`` and ``Sockets`` interfaces:
220+
221+.. code-block:: idris
222+
223+ startServer : (ConsoleIO m, Sockets m) => ST m () []
224+
225+The first thing we need to do is create a socket for binding to a port
226+and listening for incoming connections, using ``socket``. This might fail,
227+so we'll need to deal with the case where it returns ``Right sock``, where
228+``sock`` is the new socket variable, or where it returns ``Left err``:
229+
230+.. code-block:: idris
231+
232+ startServer : (ConsoleIO m, Sockets m) => ST m () []
233+ startServer =
234+ do Right sock <- socket Stream
235+ | Left err => pure ()
236+ ?whatNow
237+
238+It's a good idea to implement this kind of function interactively, step by
239+step, using holes to see what state the overall system is in after each
240+step. Here, we can see that after a successful call to ``socket``, we
241+have a socket available in the ``Ready`` state:
242+
243+.. code-block:: idris
244+
245+ sock : Var
246+ m : Type -> Type
247+ constraint : ConsoleIO m
248+ constraint1 : Sockets m
249+ --------------------------------------
250+ whatNow : STrans m () [sock ::: Sock Ready] (\result1 => [])
251+
252+Next, we need to bind the socket to a port, and start listening for
253+connections. Again, each of these could fail. If they do, we'll remove
254+the socket. Failure always results in a socket in the ``Closed`` state,
255+so all we can do is ``remove`` it:
256+
257+.. code-block:: idris
258+
259+ startServer : (ConsoleIO m, Sockets m) => ST m () []
260+ startServer =
261+ do Right sock <- socket Stream | Left err => pure ()
262+ Right ok <- bind sock Nothing 9442 | Left err => remove sock
263+ Right ok <- listen sock | Left err => remove sock
264+ ?runServer
265+
266+Finally, we have a socket which is listening for incoming connections:
267+
268+.. code-block:: idris
269+
270+ ok : ()
271+ sock : Var
272+ ok1 : ()
273+ m : Type -> Type
274+ constraint : ConsoleIO m
275+ constraint1 : Sockets m
276+ --------------------------------------
277+ runServer : STrans m () [sock ::: Sock Listening]
278+ (\result1 => [])
279+
280+We'll implement this in a separate function. The type of ``runServer``
281+tells us what the type of ``echoServer`` must be (noting that we need
282+to give the ``m`` argument to ``Sock`` explicitly):
283+
284+.. code-block:: idris
285+
286+ echoServer : (ConsoleIO m, Sockets m) => (sock : Var) ->
287+ ST m () [remove sock (Sock {m} Listening)]
288+
289+We can complete the definition of ``startServer`` as follows:
290+
291+.. code-block:: idris
292+
293+ startServer : (ConsoleIO m, Sockets m) => ST m () []
294+ startServer =
295+ do Right sock <- socket Stream | Left err => pure ()
296+ Right ok <- bind sock Nothing 9442 | Left err => remove sock
297+ Right ok <- listen sock | Left err => remove sock
298+ echoServer sock
299+
300+In ``echoServer``, we'll keep accepting requests and responding to them
301+until something fails, at which point we'll close the sockets and
302+return. We begin by trying to accept an incoming connection:
303+
304+.. code-block:: idris
305+
306+ echoServer : (ConsoleIO m, Sockets m) => (sock : Var) ->
307+ ST m () [remove sock (Sock {m} Listening)]
308+ echoServer sock =
309+ do Right new <- accept sock | Left err => do close sock; remove sock
310+ ?whatNow
311+
312+If ``accept`` fails, we need to close the ``Listening`` socket and
313+remove it before returning, because the type of ``echoServer`` requires
314+this.
315+
316+As always, implementing ``echoServer`` incrementally means that we can check
317+the state we're in as we develop. If ``accept`` succeeds, we have the
318+existing ``sock`` which is still listening for connections, and a ``new``
319+socket, which is open for communication:
320+
321+.. code-block:: idris
322+
323+ new : Var
324+ sock : Var
325+ m : Type -> Type
326+ constraint : ConsoleIO m
327+ constraint1 : Sockets m
328+ --------------------------------------
329+ whatNow : STrans m () [sock ::: Sock Listening, new ::: Sock Open]
330+ (\result1 => [])
331+
332+To complete ``echoServer``, we'll receive a message on the ``new``
333+socket, and echo it back. When we're done, we close the ``new`` socket,
334+and go back to the beginning of ``echoServer`` to handle the next
335+connection:
336+
337+.. code-block:: idris
338+
339+ echoServer : (ConsoleIO m, Sockets m) => (sock : Var) ->
340+ ST m () [remove sock (Sock {m} Listening)]
341+ echoServer sock =
342+ do Right new <- accept sock | Left err => do close sock; remove sock
343+ Right msg <- recv new | Left err => do close sock; remove sock; remove new
344+ Right ok <- send new ("You said " ++ msg)
345+ | Left err => do remove new; close sock; remove sock
346+ close new; remove new; echoServer sock
347+
348+Implementing ``Sockets``
349+========================
350+
351+To implement ``Sockets`` in ``IO``, we'll begin by giving a concrete type
352+for ``Sock``. We can use the raw sockets API (implemented in
353+``Network.Socket``) for this, and use a ``Socket`` stored in a ``State``, no
354+matter what abstract state the socket is in:
355+
356+.. code-block:: idris
357+
358+ implementation Sockets IO where
359+ Sock _ = State Socket
360+
361+Most of the methods can be implemented by using the raw socket API
362+directly, returning ``Left`` or ``Right`` as appropriate. For example,
363+we can implement ``socket``, ``bind`` and ``listen`` as follows:
364+
365+.. code-block:: idris
366+
367+ socket ty = do Right sock <- lift $ Socket.socket AF_INET ty 0
368+ | Left err => pure (Left ())
369+ lbl <- new sock
370+ pure (Right lbl)
371+ bind sock addr port = do ok <- lift $ bind !(read sock) addr port
372+ if ok /= 0
373+ then pure (Left ())
374+ else pure (Right ())
375+ listen sock = do ok <- lift $ listen !(read sock)
376+ if ok /= 0
377+ then pure (Left ())
378+ else pure (Right ())
379+
380+There is a small difficulty with ``accept``, however, because when we
381+use ``new`` to create a new resource for the open connection, it appears
382+at the *start* of the resource list, not the end. We can see this by
383+writing an incomplete definition, using ``returning`` to see what the
384+resources need to be if we return ``Right lbl``:
385+
386+.. code-block:: idris
387+
388+ accept sock = do Right (conn, addr) <- lift $ accept !(read sock)
389+ | Left err => pure (Left ())
390+ lbl <- new conn
391+ returning (Right lbl) ?fixResources
392+
393+It's convenient for ``new`` to add the resource to the beginning of the
394+list because, in general, this makes automatic proof construction with
395+an ``auto``-implicit easier for Idris. On the other hand, when we use
396+``call`` to make a smaller set of resources, ``updateWith`` puts newly
397+created resources at the *end* of the list, because in general that reduces
398+the amount of re-ordering of resources.
399+
400+If we look at the type of
401+``fixResources``, we can see what we need to do to finish ``accept``:
402+
403+.. code-block:: idris
404+
405+ _bindApp0 : Socket
406+ conn : Socket
407+ addr : SocketAddress
408+ sock : Var
409+ lbl : Var
410+ --------------------------------------
411+ fixResources : STrans IO () [lbl ::: State Socket, sock ::: State Socket]
412+ (\value => [sock ::: State Socket, lbl ::: State Socket])
413+
414+The current list of resources is ordered ``lbl``, ``sock``, and we need them
415+to be in the order ``sock``, ``lbl``. To help with this situation,
416+``Control.ST`` provides a primitive ``toEnd`` which moves a resource to the
417+end of the list. We can therefore complete ``accept`` as follows:
418+
419+.. code-block:: idris
420+
421+ accept sock = do Right (conn, addr) <- lift $ accept !(read sock)
422+ | Left err => pure (Left ())
423+ lbl <- new conn
424+ returning (Right lbl) (toEnd lbl)
425+
426+For the complete implementation of ``Sockets``, take a look at
427+``samples/ST/Net/Network.idr`` in the Idris distribution. You can also
428+find the complete echo server there, ``EchoServer.idr``. There is also
429+a higher level network protocol, ``RandServer.idr``, using a hierarchy of
430+state machines to implement a high level network communication protocol
431+in terms of the lower level sockets API. This also uses threading, to
432+handle incoming requests asynchronously. You can find some more detail
433+on threading and the random number server in the draft paper
434+`State Machines All The Way Down <https://www.idris-lang.org/drafts/sms.pdf>`_

1+********
2+Overview
3+********
4+
5+Pure functional languages with dependent types such as `Idris
6+<https://www.idris-lang.org/>`_ support reasoning about programs directly
7+in the type system, promising that we can *know* a program will run
8+correctly (i.e. according to the specification in its type) simply
9+because it compiles.
10+
11+Realistically, though, software relies on state, and many components rely on state machines. For
12+example, they describe network transport protocols like TCP, and
13+implement event-driven systems and regular expression matching. Furthermore,
14+many fundamental resources like network sockets and files are, implicitly,
15+managed by state machines, in that certain operations are only valid on
16+resources in certain states, and those operations can change the states of the
17+underlying resource. For example, it only makes sense to send a message on a
18+connected network socket, and closing a socket changes its state from "open" to
19+"closed". State machines can also encode important security properties. For
20+example, in the software which implements an ATM, it’s important that the ATM
21+dispenses cash only when the machine is in a state where a card has been
22+inserted and the PIN verified.
23+
24+In this tutorial we will introduce the ``Control.ST`` library, which is included
25+with the Idris distribution (currently as part of the ``contrib`` package)
26+and supports programming and reasoning with state and side effects. This
27+tutorial assumes familiarity with pure programming in Idris, as described in
28+:ref:`tutorial-index`.
29+For further background information, the ``ST`` library is based on ideas
30+discussed in Chapter 13 (available as a free sample chapter) and Chapter 14
31+of `Type-Driven Development with Idris <https://www.manning.com/books/type-driven-development-with-idris>`_.
32+
33+The ``ST`` library allows us to write programs which are composed of multiple
34+state transition systems. It supports composition in two ways: firstly, we can
35+use several independently implemented state transition systems at once;
36+secondly, we can implement one state transition system in terms of others.
37+
38+
39+Introductory example: a data store requiring a login
40+====================================================
41+
42+Many software components rely on some form of state, and there may be
43+operations which are only valid in specific states. For example, consider
44+a secure data store in which a user must log in before getting access to
45+some secret data. This system can be in one of two states:
46+
47+* ``LoggedIn``, in which the user is allowed to read the secret
48+* ``LoggedOut``, in which the user has no access to the secret
49+
50+We can provide commands to log in, log out, and read the data, as illustrated
51+in the following diagram:
52+
53+|login|
54+
55+The ``login`` command, if it succeeds, moves the overall system state from
56+``LoggedOut`` to ``LoggedIn``. The ``logout`` command moves the state from
57+``LoggedIn`` to ``LoggedOut``. Most importantly, the ``readSecret`` command
58+is only valid when the system is in the ``LoggedIn`` state.
59+
60+We routinely use type checkers to ensure that variables and arguments are used
61+consistently. However, statically checking that operations are performed only
62+on resources in an appropriate state is not well supported by mainstream type
63+systems. In the data store example, for example, it's important to check that
64+the user is successfully logged in before using ``readSecret``. The
65+``ST`` library allows us to represent this kind of *protocol* in the type
66+system, and ensure at *compile-time* that the secret is only read when the
67+user is logged in.
68+
69+Outline
70+=======
71+
72+This tutorial starts (:ref:`introst`) by describing how to manipulate
73+individual states, introduces a data type ``STrans`` for describing stateful
74+functions, and ``ST`` which describes top level state transitions.
75+Next (:ref:`smstypes`) it describes how to represent state machines in
76+types, and how to define *interfaces* for describing stateful systems.
77+Then (:ref:`composing`) it describes how to compose systems of multiple
78+state machines. It explains how to implement systems which use several
79+state machines at once, and how to implement a high level stateful system
80+in terms of lower level systems.
81+Finally (:ref:`netexample`) we'll see a specific example of a stateful
82+API in practice, implementing the POSIX network sockets API.
83+
84+The ``Control.ST`` library is also described in a draft paper by
85+`Edwin Brady <https://edwinb.wordpress.com/>`_, "State Machines All The Way
86+Down", available `here <https://www.idris-lang.org/drafts/sms.pdf>`_.
87+This paper presents many of the examples from this tutorial, and describes
88+the motivation, design and implementation of the library in more depth.

3+***********************
4+State Machines in Types
5+***********************
6+
7+In the introduction, we saw the following state transition diagram representing
8+the (abstract) states of a data store, and the actions we can perform on the
9+store:
10+
11+|login|
12+
13+We say that these are the *abstract* states of the store, because the concrete
14+state will contain a lot more information: for example, it might contain
15+user names, hashed passwords, the store contents, and so on. However, as far
16+as we are concerned for the actions ``login``, ``logout`` and ``readSecret``,
17+it's whether we are logged in or not which affects which are valid.
18+
19+We've seen how to manipulate states using ``ST``, and some small examples
20+of dependent types in states. In this section, we'll see how to use
21+``ST`` to provide a safe API for the data store. In the API, we'll encode
22+the above diagram in the types, in such a way that we can only execute the
23+operations ``login``, ``logout`` and ``readSecret`` when the state is
24+valid.
25+
26+So far, we've used ``State`` and the primitive operations, ``new``, ``read``,
27+``write`` and ``delete`` to manipulate states. For the data store API,
28+however, we'll begin by defining an *interface* (see :ref:`sect-interfaces` in
29+the Idris tutorial) which describes the operations on the store, and explains
30+in their types exactly when each operation is valid, and how it affects
31+the store's state. By using an interface, we can be sure that
32+this is the *only* way to access the store.
33+
34+Defining an interface for the data store
35+========================================
36+
37+We'll begin by defining a data type, in a file ``Login.idr``, which represents
38+the two abstract states of the store, either ``LoggedOut`` or ``LoggedIn``:
39+
40+.. code-block:: idris
41+
42+ data Access = LoggedOut | LoggedIn
43+
44+We can define a data type for representing the current state of a store,
45+holding all of the necessary information (this might be user names, hashed
46+passwords, store contents and so on) and parameterise it by the logged in
47+status of the store:
48+
49+.. code-block:: idris
50+
51+ Store : Access -> Type
52+
53+Rather than defining a concrete type now, however, we'll include this in
54+a data store *interface* and define a concrete type later:
55+
56+.. code-block:: idris
57+
58+ interface DataStore (m : Type -> Type) where
59+ Store : Access -> Type
60+
61+We can continue to populate this interface with operations on the store. Among
62+other advantages, by separating the *interface* from its *implementation* we
63+can provide different concrete implementations for different contexts.
64+Furthermore, we can write programs which work with a store without needing
65+to know any details of how the store is implemented.
66+
67+We'll need to be able to ``connect`` to a store, and ``disconnect`` when
68+we're done. Add the following methods to the ``DataStore`` interface:
69+
70+.. code-block:: idris
71+
72+ connect : ST m Var [add (Store LoggedOut)]
73+ disconnect : (store : Var) -> ST m () [remove store (Store LoggedOut)]
74+
75+The type of ``connect`` says that it returns a new resource which has the
76+initial type ``Store LoggedOut``. Conversely, ``disconnect``, given a
77+resource in the state ``Store LoggedOut``, removes that resource.
78+We can see more clearly what ``connect`` does by trying the following
79+(incomplete) definition:
80+
81+.. code-block:: idris
82+
83+ doConnect : DataStore m => ST m () []
84+ doConnect = do st <- connect
85+ ?whatNow
86+
87+Note that we're working in a *generic* context ``m``, constrained so that
88+there must be an implementation of ``DataStore`` for ``m`` to be able to
89+execute ``doConnect``.
90+If we check the type of ``?whatNow``, we'll see that the remaining
91+operations begin with a resource ``st`` in the state ``Store LoggedOut``,
92+and we need to finish with no resources.
93+
94+.. code-block:: idris
95+
96+ m : Type -> Type
97+ constraint : DataStore m
98+ st : Var
99+ --------------------------------------
100+ whatNow : STrans m () [st ::: Store LoggedOut] (\result => [])
101+
102+Then, we can remove the resource using ``disconnect``:
103+
104+.. code-block:: idris
105+
106+ doConnect : DataStore m => ST m () []
107+ doConnect = do st <- connect
108+ disconnect st
109+ ?whatNow
110+
111+Now checking the type of ``?whatNow`` shows that we have no resources
112+available:
113+
114+.. code-block:: idris
115+
116+ m : Type -> Type
117+ constraint : DataStore m
118+ st : Var
119+ --------------------------------------
120+ whatNow : STrans m () [] (\result => [])
121+
122+To continue our implementation of the ``DataStore`` interface, next we'll add a
123+method for reading the secret data. This requires that the ``store`` is in the
124+state ``Store LoggedIn``:
125+
126+.. code-block:: idris
127+
128+ readSecret : (store : Var) -> ST m String [store ::: Store LoggedIn]
129+
130+At this point we can try writing a function which connects to a store,
131+reads the secret, then disconnects. However, it will be unsuccessful, because
132+``readSecret`` requires us to be logged in:
133+
134+.. code-block:: idris
135+
136+ badGet : DataStore m => ST m () []
137+ badGet = do st <- connect
138+ secret <- readSecret st
139+ disconnect st
140+
141+This results in the following error, because ``connect`` creates a new
142+store in the ``LoggedOut`` state, and ``readSecret`` requires the store
143+to be in the ``LoggedIn`` state:
144+
145+.. code-block:: idris
146+
147+ When checking an application of function Control.ST.>>=:
148+ Error in state transition:
149+ Operation has preconditions: [st ::: Store LoggedOut]
150+ States here are: [st ::: Store LoggedIn]
151+ Operation has postconditions: \result => []
152+ Required result states here are: \result => []
153+
154+The error message explains how the required input states (the preconditions)
155+and the required output states (the postconditions) differ from the states
156+in the operation. In order to use ``readSecret``, we'll need a way to get
157+from a ``Store LoggedOut`` to a ``Store LoggedIn``. As a first attempt,
158+we can try the following type for ``login``:
159+
160+.. code-block:: idris
161+
162+ login : (store : Var) -> ST m () [store ::: Store LoggedOut :-> Store LoggedIn] -- Incorrect type!
163+
164+Note that in the *interface* we say nothing about *how* ``login`` works;
165+merely how it affects the overall state. Even so, there is a problem with
166+the type of ``login``, because it makes the assumption that it will always
167+succeed. If it fails - for example because the implementation prompts for
168+a password and the user enters the password incorrectly - then it must not
169+result in a ``LoggedIn`` store.
170+
171+Instead, therefore, ``login`` will return whether logging in was successful,
172+via the following type;
173+
174+.. code-block:: idris
175+
176+ data LoginResult = OK | BadPassword
177+
178+Then, we can *calculate* the result state (see :ref:`depstate`) from the
179+result. Add the following method to the ``DataStore`` interface:
180+
181+.. code-block:: idris
182+
183+ login : (store : Var) ->
184+ ST m LoginResult [store ::: Store LoggedOut :->
185+ (\res => Store (case res of
186+ OK => LoggedIn
187+ BadPassword => LoggedOut))]
188+
189+If ``login`` was successful, then the state after ``login`` is
190+``Store LoggedIn``. Otherwise, the state is ``Store LoggedOut``.
191+
192+To complete the interface, we'll add a method for logging out of the store.
193+We'll assume that logging out is always successful, and moves the store
194+from the ``Store LoggedIn`` state to the ``Store LoggedOut`` state.
195+
196+.. code-block:: idris
197+
198+ logout : (store : Var) -> ST m () [store ::: Store LoggedIn :-> Store LoggedOut]
199+
200+This completes the interface, repeated in full for reference below:
201+
202+.. code-block:: idris
203+
204+ interface DataStore (m : Type -> Type) where
205+ Store : Access -> Type
206+
207+ connect : ST m Var [add (Store LoggedOut)]
208+ disconnect : (store : Var) -> ST m () [remove store (Store LoggedOut)]
209+
210+ readSecret : (store : Var) -> ST m String [store ::: Store LoggedIn]
211+ login : (store : Var) ->
212+ ST m LoginResult [store ::: Store LoggedOut :->
213+ (\res => Store (case res of
214+ OK => LoggedIn
215+ BadPassword => LoggedOut))]
216+ logout : (store : Var) -> ST m () [store ::: Store LoggedIn :-> Store LoggedOut]
217+
218+Before we try creating any implementations of this interface, let's see how
219+we can write a function with it, to log into a data store, read the secret
220+if login is successful, then log out again.
221+
222+Writing a function with the data store
223+======================================
224+
225+As an example of working with the ``DataStore`` interface, we'll write a
226+function ``getData``, which connects to a store in order to read some data from
227+it. We'll write this function interactively, step by step, using the types of
228+the operations to guide its development. It has the following type:
229+
230+.. code-block:: idris
231+
232+ getData : (ConsoleIO m, DataStore m) => ST m () []
233+
234+This type means that there are no resources available on entry or exit.
235+That is, the overall list of actions is ``[]``, meaning that at least
236+externally, the function has no overall effect on the resources. In other
237+words, for every resource we create during ``getData``, we'll also need to
238+delete it before exit.
239+
240+Since we want to use methods of the ``DataStore`` interface, we'll
241+constraint the computation context ``m`` so that there must be an
242+implementation of ``DataStore``. We also have a constraint ``ConsoleIO m``
243+so that we can display any data we read from the store, or any error
244+messages.
245+
246+We start by connecting to the store, creating a new resource ``st``, then
247+trying to ``login``:
248+
249+.. code-block:: idris
250+
251+ getData : (ConsoleIO m, DataStore m) => ST m () []
252+ getData = do st <- connect
253+ ok <- login st
254+ ?whatNow
255+
256+Logging in will either succeed or fail, as reflected by the value of
257+``ok``. If we check the type of ``?whatNow``, we'll see what state the
258+store currently has:
259+
260+.. code-block:: idris
261+
262+ m : Type -> Type
263+ constraint : ConsoleIO m
264+ constraint1 : DataStore m
265+ st : Var
266+ ok : LoginResult
267+ --------------------------------------
268+ whatNow : STrans m () [st ::: Store (case ok of
269+ OK => LoggedIn
270+ BadPassword => LoggedOut)]
271+ (\result => [])
272+
273+The current state of ``st`` therefore depends on the value of ``ok``,
274+meaning that we can make progress by case splitting on ``ok``:
275+
276+.. code-block:: idris
277+
278+ getData : (ConsoleIO m, DataStore m) => ST m () []
279+ getData = do st <- connect
280+ ok <- login st
281+ case ok of
282+ OK => ?whatNow_1
283+ BadPassword => ?whatNow_2
284+
285+The types of the holes in each branch, ``?whatNow_1`` and ``?whatNow_2``,
286+show how the state changes depending on whether logging in was successful.
287+If it succeeded, the store is ``LoggedIn``:
288+
289+.. code-block:: idris
290+
291+ --------------------------------------
292+ whatNow_1 : STrans m () [st ::: Store LoggedIn] (\result => [])
293+
294+On the other hand, if it failed, the store is ``LoggedOut``:
295+
296+.. code-block:: idris
297+
298+ --------------------------------------
299+ whatNow_2 : STrans m () [st ::: Store LoggedOut] (\result => [])
300+
301+In ``?whatNow_1``, since we've successfully logged in, we can now read
302+the secret and display it to the console:
303+
304+.. code-block:: idris
305+
306+ getData : (ConsoleIO m, DataStore m) => ST m () []
307+ getData = do st <- connect
308+ ok <- login st
309+ case ok of
310+ OK => do secret <- readSecret st
311+ putStrLn ("Secret is: " ++ show secret)
312+ ?whatNow_1
313+ BadPassword => ?whatNow_2
314+
315+We need to finish the ``OK`` branch with no resources available. We can
316+do this by logging out of the store then disconnecting:
317+
318+.. code-block:: idris
319+
320+ getData : (ConsoleIO m, DataStore m) => ST m () []
321+ getData = do st <- connect
322+ ok <- login st
323+ case ok of
324+ OK => do secret <- readSecret st
325+ putStrLn ("Secret is: " ++ show secret)
326+ logout st
327+ disconnect st
328+ BadPassword => ?whatNow_2
329+
330+Note that we *must* ``logout`` of ``st`` before calling ``disconnect``,
331+because ``disconnect`` requires that the store is in the ``LoggedOut``
332+state.
333+
334+Furthermore, we can't simply use ``delete`` to remove the resource, as
335+we did with the ``State`` examples in the previous section, because
336+``delete`` only works when the resource has type ``State ty``, for some
337+type ``ty``. If we try to use ``delete`` instead of ``disconnect``, we'll
338+see an error message like the following:
339+
340+.. code-block:: idris
341+
342+ When checking argument prf to function Control.ST.delete:
343+ Can't find a value of type
344+ InState st (State st) [st ::: Store LoggedOut]
345+
346+In other words, the type checker can't find a proof that the resource
347+``st`` has a type of the form ``State st``, because its type is
348+``Store LoggedOut``. Since ``Store`` is part of the ``DataStore`` interface,
349+we *can't* yet know the concrete representation of the ``Store``, so we
350+need to remove the resource via the interface, with ``disconnect``, rather
351+than directly with ``delete``.
352+
353+We can complete ``getData`` as follows, using a pattern matching bind
354+alternative (see the Idris tutorial, :ref:`monadsdo`) rather than a
355+``case`` statement to catch the possibility of an error with ``login``:
356+
357+.. code-block:: idris
358+
359+ getData : (ConsoleIO m, DataStore m) => ST m () []
360+ getData = do st <- connect
361+ OK <- login st
362+ | BadPassword => do putStrLn "Failure"
363+ disconnect st
364+ secret <- readSecret st
365+ putStrLn ("Secret is: " ++ show secret)
366+ logout st
367+ disconnect st
368+
369+We can't yet try this out, however, because we don't have any implementations
370+of ``DataStore``! If we try to execute it in an ``IO`` context, for example,
371+we'll get an error saying that there's no implementation of ``DataStore IO``:
372+
373+.. code::
374+
375+ *Login> :exec run {m = IO} getData
376+ When checking an application of function Control.ST.run:
377+ Can't find implementation for DataStore IO
378+
379+The final step in implementing a data store which correctly follows the
380+state transition diagram, therefore, is to provide an implementation
381+of ``DataStore``.
382+
383+Implementing the interface
384+==========================
385+
386+To execute ``getData`` in ``IO``, we'll need to provide an implementation
387+of ``DataStore`` which works in the ``IO`` context. We can begin as
388+follows:
389+
390+.. code-block:: idris
391+
392+ implementation DataStore IO where
393+
394+Then, we can ask Idris to populate the interface with skeleton definitions
395+for the necessary methods (press ``Ctrl-Alt-A`` in Atom for "add definition"
396+or the corresponding shortcut for this in the Idris mode in your favourite
397+editor):
398+
399+.. code-block:: idris
400+
401+ implementation DataStore IO where
402+ Store x = ?DataStore_rhs_1
403+ connect = ?DataStore_rhs_2
404+ disconnect store = ?DataStore_rhs_3
405+ readSecret store = ?DataStore_rhs_4
406+ login store = ?DataStore_rhs_5
407+ logout store = ?DataStore_rhs_6
408+
409+The first decision we'll need to make is how to represent the data store.
410+We'll keep this simple, and store the data as a single ``String``, using
411+a hard coded password to gain access. So, we can define ``Store`` as
412+follows, using a ``String`` to represent the data no matter whether we
413+are ``LoggedOut`` or ``LoggedIn``:
414+
415+.. code-block:: idris
416+
417+ Store x = State String
418+
419+Now that we've given a concrete type for ``Store``, we can implement operations
420+for connecting, disconnecting, and accessing the data. And, since we used
421+``State``, we can use ``new``, ``delete``, ``read`` and ``write`` to
422+manipulate the store.
423+
424+Looking at the types of the holes tells us how we need to manipulate the
425+state. For example, the ``?DataStore_rhs_2`` hole tells us what we need
426+to do to implement ``connect``. We need to return a new ``Var`` which
427+represents a resource of type ``State String``:
428+
429+.. code-block:: idris
430+
431+ --------------------------------------
432+ DataStore_rhs_2 : STrans IO Var [] (\result => [result ::: State String])
433+
434+We can implement this by creating a new variable with some data for the
435+content of the store (we can use any ``String`` for this) and returning
436+that variable:
437+
438+.. code-block:: idris
439+
440+ connect = do store <- new "Secret Data"
441+ pure store
442+
443+For ``disconnect``, we only need to delete the resource:
444+
445+.. code-block:: idris
446+
447+ disconnect store = delete store
448+
449+For ``readSecret``, we need to read the secret data and return the
450+``String``. Since we now know the concrete representation of the data is
451+a ``State String``, we can use ``read`` to access the data directly:
452+
453+.. code-block:: idris
454+
455+ readSecret store = read store
456+
457+We'll do ``logout`` next and return to ``login``. Checking the hole
458+reveals the following:
459+
460+.. code-block:: idris
461+
462+ store : Var
463+ --------------------------------------
464+ DataStore_rhs_6 : STrans IO () [store ::: State String] (\result => [store ::: State String])
465+
466+So, in this minimal implementation, we don't actually have to do anything!
467+
468+.. code-block:: idris
469+
470+ logout store = pure ()
471+
472+For ``login``, we need to return whether logging in was successful. We'll
473+do this by prompting for a password, and returning ``OK`` if it matches
474+a hard coded password, or ``BadPassword`` otherwise:
475+
476+.. code-block:: idris
477+
478+ login store = do putStr "Enter password: "
479+ p <- getStr
480+ if p == "Mornington Crescent"
481+ then pure OK
482+ else pure BadPassword
483+
484+For reference, here is the complete implementation which allows us to
485+execute a ``DataStore`` program at the REPL:
486+
487+.. code-block:: idris
488+
489+ implementation DataStore IO where
490+ Store x = State String
491+ connect = do store <- new "Secret Data"
492+ pure store
493+ disconnect store = delete store
494+ readSecret store = read store
495+ login store = do putStr "Enter password: "
496+ p <- getStr
497+ if p == "Mornington Crescent"
498+ then pure OK
499+ else pure BadPassword
500+ logout store = pure ()
501+
502+Finally, we can try this at the REPL as follows (Idris defaults to the
503+``IO`` context at the REPL if there is an implementation available, so no
504+need to give the ``m`` argument explicitly here):
505+
506+.. code::
507+
508+ *Login> :exec run getData
509+ Enter password: Mornington Crescent
510+ Secret is: "Secret Data"
511+
512+ *Login> :exec run getData
513+ Enter password: Dollis Hill
514+ Failure
515+
516+We can only use ``read``, ``write``, ``new`` and ``delete`` on a resource
517+with a ``State`` type. So, *within* the implementation of ``DataStore``,
518+or anywhere where we know the context is ``IO``, we can access the data store
519+however we like: this is where the internal details of ``DataStore`` are
520+implemented. However, if we merely have a constraint ``DataStore m``, we can't
521+know how the store is implemented, so we can only access via the API given
522+by the ``DataStore`` interface.
523+
524+It is therefore good practice to use a *generic* context ``m`` for functions
525+like ``getData``, and constrain by only the interfaces we need, rather than
526+using a concrete context ``IO``.
527+
528+We've now seen how to manipulate states, and how to encapsulate state
529+transitions for a specific system like the data store in an interface.
530+However, realistic systems will need to *compose* state machines. We'll
531+either need to use more than one state machine at a time, or implement one
532+state machine in terms of one or more others. We'll see how to achieve this
533+in the next section.

3+**********************************
4+Introducing ST: Working with State
5+**********************************
6+
7+The ``Control.ST`` library provides facilities for creating, reading, writing
8+and destroying state in Idris functions, and tracking changes of state in
9+a function's type. It is based around the concept of *resources*, which are,
10+essentially, mutable variables, and a dependent type, ``STrans`` which tracks
11+how those resources change when a function runs:
12+
13+.. code-block:: idris
14+
15+ STrans : (m : Type -> Type) ->
16+ (resultType : Type) ->
17+ (in_res : Resources) ->
18+ (out_res : resultType -> Resources) ->
19+ Type
20+
21+A value of type ``STrans m resultType in_res out_res_fn`` represents a sequence
22+of actions which can manipulate state. The arguments are:
23+
24+* ``m``, which is an underlying *computation context* in which the actions will be executed.
25+ Usually, this will be a generic type with a ``Monad`` implementation, but
26+ it isn't necessarily so. In particular, there is no need to understand monads
27+ to be able to use ``ST`` effectively!
28+* ``resultType``, which is the type of the value the sequence will produce
29+* ``in_res``, which is a list of *resources* available *before* executing the actions.
30+* ``out_res``, which is a list of resources available *after* executing the actions,
31+ and may differ depending on the result of the actions.
32+
33+We can use ``STrans`` to describe *state transition systems* in a function's
34+type. We'll come to the definition of ``Resources`` shortly, but for the moment
35+you can consider it an abstract representation of the "state of the world".
36+By giving the input resources (``in_res``) and the output resources
37+(``out_res``) we are describing the *preconditions* under which a function
38+is allowed to execute, and *postconditions* which describe how a function
39+affects the overall state of the world.
40+
41+We'll begin in this section by looking at some small examples of ``STrans``
42+functions, and see how to execute them. We'll also introduce ``ST``,
43+a type-level function which allows us to describe the state transitions of
44+a stateful function concisely.
45+
46+.. topic:: Type checking the examples
47+
48+ For the examples in this section, and throughout this tutorial,
49+ you'll need to ``import Control.ST`` and add the ``contrib`` package by
50+ passing the ``-p contrib`` flag to ``idris``.
51+
52+
53+Introductory examples: manipulating ``State``
54+=============================================
55+
56+An ``STrans`` function explains, in its type, how it affects a collection of
57+``Resources``. A resource has a *label* (of type ``Var``), which we use to
58+refer to the resource throughout the function, and we write the state of a
59+resource, in the ``Resources`` list, in the form ``label ::: type``.
60+
61+For example, the following function
62+has a resource ``x`` available on input, of type ``State Integer``, and that
63+resource is still a ``State Integer`` on output:
64+
65+.. code-block:: idris
66+
67+ increment : (x : Var) -> STrans m () [x ::: State Integer]
68+ (const [x ::: State Integer])
69+ increment x = do num <- read x
70+ write x (num + 1)
71+
72+.. sidebar:: Verbosity of the type of ``increment``
73+
74+ The type of ``increment`` may seem somewhat verbose, in that the
75+ *input* and *output* resources are repeated, even though they are the
76+ same. We'll introduce a much more concise way of writing this type at the
77+ end of this section (:ref:`sttype`), when we describe the ``ST`` type
78+ itself.
79+
80+This function reads the value stored at the resource ``x`` with ``read``,
81+increments it then writes the result back into the resource ``x`` with
82+``write``. We'll see the types of ``read`` and ``write`` shortly
83+(see :ref:`stransprimops`). We can also create and delete resources:
84+
85+.. code-block:: idris
86+
87+ makeAndIncrement : Integer -> STrans m Integer [] (const [])
88+ makeAndIncrement init = do var <- new init
89+ increment var
90+ x <- read var
91+ delete var
92+ pure x
93+
94+The type of ``makeAndIncrement`` states that it has *no* resources available on
95+entry (``[]``) or exit (``const []``). It creates a new ``State`` resource with
96+``new`` (which takes an initial value for the resource), increments the value,
97+reads it back, then deletes it using ``delete``, returning the final value
98+of the resource. Again, we'll see the types of ``new`` and ``delete``
99+shortly.
100+
101+The ``m`` argument to ``STrans`` (of type ``Type -> Type``) is the *computation context* in
102+which the function can be run. Here, the type level variable indicates that we
103+can run it in *any* context. We can run it in the identity context with
104+``runPure``. For example, try entering the above definitions in a file
105+``Intro.idr`` then running the following at the REPL:
106+
107+.. code::
108+
109+ *Intro> runPure (makeAndIncrement 93)
110+ 94 : Integer
111+
112+It's a good idea to take an interactive, type-driven approach to implementing
113+``STrans`` programs. For example, after creating the resource with ``new init``,
114+you can leave a *hole* for the rest of the program to see how creating the
115+resource has affected the type:
116+
117+.. code-block:: idris
118+
119+ makeAndIncrement : Integer -> STrans m Integer [] (const [])
120+ makeAndIncrement init = do var <- new init
121+ ?whatNext
122+
123+If you check the type of ``?whatNext``, you'll see that there is now
124+a resource available, ``var``, and that by the end of the function there
125+should be no resource available:
126+
127+.. code-block:: idris
128+
129+ init : Integer
130+ m : Type -> Type
131+ var : Var
132+ --------------------------------------
133+ whatNext : STrans m Integer [var ::: State Integer] (\value => [])
134+
135+These small examples work in any computation context ``m``. However, usually,
136+we are working in a more restricted context. For example, we might want to
137+write programs which only work in a context that supports interactive
138+programs. For this, we'll need to see how to *lift* operations from the
139+underlying context.
140+
141+Lifting: Using the computation context
142+======================================
143+
144+Let's say that, instead of passing an initial integer to ``makeAndIncrement``,
145+we want to read it in from the console. Then, instead of working in a generic
146+context ``m``, we can work in the specific context ``IO``:
147+
148+.. code-block:: idris
149+
150+ ioMakeAndIncrement : STrans IO () [] (const [])
151+
152+This gives us access to ``IO`` operations, via the ``lift`` function. We
153+can define ``ioMakeAndIncrement`` as follows:
154+
155+.. code-block:: idris
156+
157+ ioMakeAndIncrement : STrans IO () [] (const [])
158+ ioMakeAndIncrement
159+ = do lift $ putStr "Enter a number: "
160+ init <- lift $ getLine
161+ var <- new (cast init)
162+ lift $ putStrLn ("var = " ++ show !(read var))
163+ increment var
164+ lift $ putStrLn ("var = " ++ show !(read var))
165+ delete var
166+
167+The ``lift`` function allows us to use functions from the underlying
168+computation context (``IO`` here) directly. Again, we'll see the exact type
169+of ``lift`` shortly.
170+
171+.. topic:: !-notation
172+
173+ In ``ioMakeAndIncrement`` we've used ``!(read var)`` to read from the
174+ resource. You can read about this ``!``-notation in the main Idris tutorial
175+ (see :ref:`monadsdo`). In short, it allows us to use an ``STrans``
176+ function inline, rather than having to bind the result to a variable
177+ first.
178+
179+ Conceptually, at least, you can think of it as having the following type:
180+
181+ .. code-block:: idris
182+
183+ (!) : STrans m a state_in state_out -> a
184+
185+ It is syntactic sugar for binding a variable immediately before the
186+ current action in a ``do`` block, then using that variable in place of
187+ the ``!``-expression.
188+
189+
190+In general, though, it's bad practice to use a *specific* context like
191+``IO``. Firstly, it requires us to sprinkle ``lift`` liberally throughout
192+our code, which hinders readability. Secondly, and more importantly, it will
193+limit the safety of our functions, as we'll see in the next section
194+(:ref:`smstypes`).
195+
196+So, instead, we define *interfaces* to restrict the computation context.
197+For example, ``Control.ST`` defines a ``ConsoleIO`` interface which
198+provides the necessary methods for performing basic console interaction:
199+
200+.. code-block:: idris
201+
202+ interface ConsoleIO (m : Type -> Type) where
203+ putStr : String -> STrans m () res (const res)
204+ getStr : STrans m String res (const res)
205+
206+That is, we can write to and read from the console with any available
207+resources ``res``, and neither will affect the available resources.
208+This has the following implementation for ``IO``:
209+
210+.. code-block:: idris
211+
212+ ConsoleIO IO where
213+ putStr str = lift (Interactive.putStr str)
214+ getStr = lift Interactive.getLine
215+
216+Now, we can define ``ioMakeAndIncrement`` as follows:
217+
218+.. code-block:: idris
219+
220+ ioMakeAndIncrement : ConsoleIO io => STrans io () [] (const [])
221+ ioMakeAndIncrement
222+ = do putStr "Enter a number: "
223+ init <- getStr
224+ var <- new (cast init)
225+ putStrLn ("var = " ++ show !(read var))
226+ increment var
227+ putStrLn ("var = " ++ show !(read var))
228+ delete var
229+
230+Instead of working in ``IO`` specifically, this works in a generic context
231+``io``, provided that there is an implementation of ``ConsoleIO`` for that
232+context. This has several advantages over the first version:
233+
234+* All of the calls to ``lift`` are in the implementation of the interface,
235+ rather than ``ioMakeAndIncrement``
236+* We can provide alternative implementations of ``ConsoleIO``, perhaps
237+ supporting exceptions or logging in addition to basic I/O.
238+* As we'll see in the next section (:ref:`smstypes`), it will allow us to
239+ define safe APIs for manipulating specific resources more precisely.
240+
241+Earlier, we used ``runPure`` to run ``makeAndIncrement`` in the identity
242+context. Here, we use ``run``, which allows us to execute an ``STrans`` program
243+in any context (as long as it has an implementation of ``Applicative``) and we
244+can execute ``ioMakeAndIncrement`` at the REPL as follows:
245+
246+.. code::
247+
248+ *Intro> :exec run ioMakeAndIncrement
249+ Enter a number: 93
250+ var = 93
251+ var = 94
252+
253+.. _depstate:
254+
255+Manipulating ``State`` with dependent types
256+===========================================
257+
258+In our first example of ``State``, when we incremented the value its
259+*type* remained the same. However, when we're working with
260+*dependent* types, updating a state may also involve updating its type.
261+For example, if we're adding an element to a vector stored in a state,
262+its length will change:
263+
264+.. code-block:: idris
265+
266+ addElement : (vec : Var) -> (item : a) ->
267+ STrans m () [vec ::: State (Vect n a)]
268+ (const [vec ::: State (Vect (S n) a)])
269+ addElement vec item = do xs <- read vec
270+ write vec (item :: xs)
271+
272+Note that you'll need to ``import Data.Vect`` to try this example.
273+
274+.. topic:: Updating a state directly with ``update``
275+
276+ Rather than using ``read`` and ``write`` separately, you can also
277+ use ``update`` which reads from a ``State``, applies a function to it,
278+ then writes the result. Using ``update`` you could write ``addElement``
279+ as follows:
280+
281+ .. code-block:: idris
282+
283+ addElement : (vec : Var) -> (item : a) ->
284+ STrans m () [vec ::: State (Vect n a)]
285+ (const [vec ::: State (Vect (S n) a)])
286+ addElement vec item = update vec (item ::)
287+
288+We don't always know *how* exactly the type will change in the course of a
289+sequence actions, however. For example, if we have a state containing a
290+vector of integers, we might read an input from the console and only add it
291+to the vector if the input is a valid integer. Somehow, we need a different
292+type for the output state depending on whether reading the integer was
293+successful, so neither of the following types is quite right:
294+
295+.. code-block:: idris
296+
297+ readAndAdd_OK : ConsoleIO io => (vec : Var) ->
298+ STrans m () -- Returns an empty tuple
299+ [vec ::: State (Vect n Integer)]
300+ (const [vec ::: State (Vect (S n) Integer)])
301+ readAndAdd_Fail : ConsoleIO io => (vec : Var) ->
302+ STrans m () -- Returns an empty tuple
303+ [vec ::: State (Vect n Integer)]
304+ (const [vec ::: State (Vect n Integer)])
305+
306+Remember, though, that the *output* resource types can be *computed* from
307+the result of a function. So far, we've used ``const`` to note that the
308+output resources are always the same, but here, instead, we can use a type
309+level function to *calculate* the output resources. We start by returning
310+a ``Bool`` instead of an empty tuple, which is ``True`` if reading the input
311+was successful, and leave a *hole* for the output resources:
312+
313+.. code-block:: idris
314+
315+ readAndAdd : ConsoleIO io => (vec : Var) ->
316+ STrans m Bool [vec ::: State (Vect n Integer)]
317+ ?output_res
318+
319+If you check the type of ``?output_res``, you'll see that Idris expects
320+a function of type ``Bool -> Resources``, meaning that the output resource
321+type can be different depending on the result of ``readAndAdd``:
322+
323+.. code-block:: idris
324+
325+ n : Nat
326+ m : Type -> Type
327+ io : Type -> Type
328+ constraint : ConsoleIO io
329+ vec : Var
330+ --------------------------------------
331+ output_res : Bool -> Resources
332+
333+So, the output resource is either a ``Vect n Integer`` if the input is
334+invalid (i.e. ``readAndAdd`` returns ``False``) or a ``Vect (S n) Integer``
335+if the input is valid. We can express this in the type as follows:
336+
337+.. code-block:: idris
338+
339+ readAndAdd : ConsoleIO io => (vec : Var) ->
340+ STrans io Bool [vec ::: State (Vect n Integer)]
341+ (\res => [vec ::: State (if res then Vect (S n) Integer
342+ else Vect n Integer)])
343+
344+Then, when we implement ``readAndAdd`` we need to return the appropriate
345+value for the output state. If we've added an item to the vector, we need to
346+return ``True``, otherwise we need to return ``False``:
347+
348+.. code-block:: idris
349+
350+ readAndAdd : ConsoleIO io => (vec : Var) ->
351+ STrans io Bool [vec ::: State (Vect n Integer)]
352+ (\res => [vec ::: State (if res then Vect (S n) Integer
353+ else Vect n Integer)])
354+ readAndAdd vec = do putStr "Enter a number: "
355+ num <- getStr
356+ if all isDigit (unpack num)
357+ then do
358+ update vec ((cast num) ::)
359+ pure True -- added an item, so return True
360+ else pure False -- didn't add, so return False
361+
362+There is a slight difficulty if we're developing interactively, which is
363+that if we leave a hole, the required output state isn't easily visible
364+until we know the value that's being returned. For example. in the following
365+incomplete definition of ``readAndAdd`` we've left a hole for the
366+successful case:
367+
368+.. code-block:: idris
369+
370+ readAndAdd vec = do putStr "Enter a number: "
371+ num <- getStr
372+ if all isDigit (unpack num)
373+ then ?whatNow
374+ else pure False
375+
376+We can look at the type of ``?whatNow``, but it is unfortunately rather less
377+than informative:
378+
379+.. code-block:: idris
380+
381+ vec : Var
382+ n : Nat
383+ io : Type -> Type
384+ constraint : ConsoleIO io
385+ num : String
386+ --------------------------------------
387+ whatNow : STrans io Bool [vec ::: State (Vect (S n) Integer)]
388+ (\res =>
389+ [vec :::
390+ State (ifThenElse res
391+ (Delay (Vect (S n) Integer))
392+ (Delay (Vect n Integer)))])
393+
394+The problem is that we'll only know the required output state when we know
395+the value we're returning. To help with interactive development, ``Control.ST``
396+provides a function ``returning`` which allows us to specify the return
397+value up front, and to update the state accordingly. For example, we can
398+write an incomplete ``readAndAdd`` as follows:
399+
400+.. code-block:: idris
401+
402+ readAndAdd vec = do putStr "Enter a number: "
403+ num <- getStr
404+ if all isDigit (unpack num)
405+ then returning True ?whatNow
406+ else pure False
407+
408+This states that, in the successful branch, we'll be returning ``True``, and
409+``?whatNow`` should explain how to update the states appropriately so that
410+they are correct for a return value of ``True``. We can see this by checking
411+the type of ``?whatNow``, which is now a little more informative:
412+
413+.. code-block:: idris
414+
415+ vec : Var
416+ n : Nat
417+ io : Type -> Type
418+ constraint : ConsoleIO io
419+ num : String
420+ --------------------------------------
421+ whatnow : STrans io () [vec ::: State (Vect n Integer)]
422+ (\value => [vec ::: State (Vect (S n) Integer)])
423+
424+This type now shows, in the output resource list of ``STrans``,
425+that we can complete the definition by adding an item to ``vec``, which
426+we can do as follows:
427+
428+.. code-block:: idris
429+
430+ readAndAdd vec = do putStr "Enter a number: "
431+ num <- getStr
432+ if all isDigit (unpack num)
433+ then returning True (update vec ((cast num) ::))
434+ else returning False (pure ()) -- returning False, so no state update required
435+
436+.. _stransprimops:
437+
438+``STrans`` Primitive operations
439+===============================
440+
441+Now that we've written a few small examples of ``STrans`` functions, it's
442+a good time to look more closely at the types of the state manipulation
443+functions we've used. First, to read and write states, we've used
444+``read`` and ``write``:
445+
446+.. code-block:: idris
447+
448+ read : (lbl : Var) -> {auto prf : InState lbl (State ty) res} ->
449+ STrans m ty res (const res)
450+ write : (lbl : Var) -> {auto prf : InState lbl ty res} ->
451+ (val : ty') ->
452+ STrans m () res (const (updateRes res prf (State ty')))
453+
454+These types may look a little daunting at first, particularly due to the
455+implicit ``prf`` argument, which has the following type:
456+
457+.. code-block:: idris
458+
459+ prf : InState lbl (State ty) res
460+
461+This relies on a predicate ``InState``. A value of type ``InState x ty res``
462+means that the reference ``x`` must have type ``ty`` in the list of
463+resources ``res``. So, in practice, all this type means is that we can
464+only read or write a resource if a reference to it exists in the list of
465+resources.
466+
467+Given a resource label ``res``, and a proof that ``res`` exists in a list
468+of resources, ``updateRes`` will update the type of that resource. So,
469+the type of ``write`` states that the type of the resource will be updated
470+to the type of the given value.
471+
472+The type of ``update`` is similar to that for ``read`` and ``write``, requiring
473+that the resource has the input type of the given function, and updating it to
474+have the output type of the function:
475+
476+.. code-block:: idris
477+
478+ update : (lbl : Var) -> {auto prf : InState lbl (State ty) res} ->
479+ (ty -> ty') ->
480+ STrans m () res (const (updateRes res prf (State ty')))
481+
482+The type of ``new`` states that it returns a ``Var``, and given an initial
483+value of type ``state``, the output resources contains a new resource
484+of type ``State state``:
485+
486+.. code-block:: idris
487+
488+ new : (val : state) ->
489+ STrans m Var res (\lbl => (lbl ::: State state) :: res)
490+
491+It's important that the new resource has type ``State state``, rather than
492+merely ``state``, because this will allow us to hide implementation details
493+of APIs. We'll see more about what this means in the next section,
494+:ref:`smstypes`.
495+
496+The type of ``delete`` states that the given label will be removed from
497+the list of resources, given an implicit proof that the label exists in
498+the input resources:
499+
500+.. code-block:: idris
501+
502+ delete : (lbl : Var) -> {auto prf : InState lbl (State st) res} ->
503+ STrans m () res (const (drop res prf))
504+
505+Here, ``drop`` is a type level function which updates the resource list,
506+removing the given resource ``lbl`` from the list.
507+
508+We've used ``lift`` to run functions in the underlying context. It has the
509+following type:
510+
511+.. code-block:: idris
512+
513+ lift : Monad m => m t -> STrans m t res (const res)
514+
515+Given a ``result`` value, ``pure`` is an ``STrans`` program which produces
516+that value, provided that the current list of resources is correct when
517+producing that value:
518+
519+.. code-block:: idris
520+
521+ pure : (result : ty) -> STrans m ty (out_fn result) out_fn
522+
523+We can use ``returning`` to break down returning a value from an
524+``STrans`` functions into two parts: providing the value itself, and updating
525+the resource list so that it is appropriate for returning that value:
526+
527+.. code-block:: idris
528+
529+ returning : (result : ty) ->
530+ STrans m () res (const (out_fn result)) ->
531+ STrans m ty res out_fn
532+
533+Finally, we've used ``run`` and ``runPure`` to execute ``STrans`` functions
534+in a specific context. ``run`` will execute a function in any context,
535+provided that there is an ``Applicative`` implementation for that context,
536+and ``runPure`` will execute a function in the identity context:
537+
538+.. code-block:: idris
539+
540+ run : Applicative m => STrans m a [] (const []) -> m a
541+ runPure : STrans Basics.id a [] (const []) -> a
542+
543+Note that in each case, the input and output resource list must be empty.
544+There's no way to provide an initial resource list, or extract the final
545+resources. This is deliberate: it ensures that *all* resource management is
546+carried out in the controlled ``STrans`` environment and, as we'll see, this
547+allows us to implement safe APIs with precise types explaining exactly how
548+resources are tracked throughout a program.
549+
550+These functions provide the core of the ``ST`` library; there are some
551+others which we'll encounter later, for more advanced situations, but the
552+functions we have seen so far already allow quite sophisticated state-aware
553+programming and reasoning in Idris.
554+
555+.. _sttype:
556+
557+`ST`: Representing state transitions directly
558+=============================================
559+
560+We've seen a few examples of small ``STrans`` functions now, and
561+their types can become quite verbose given that we need to provide explicit
562+input and output resource lists. This is convenient for giving types for
563+the primitive operations, but for more general use it's much more convenient
564+to be able to express *transitions* on individual resources, rather than
565+giving input and output resource lists in full. We can do this with
566+``ST``:
567+
568+.. code-block:: idris
569+
570+ ST : (m : Type -> Type) ->
571+ (resultType : Type) ->
572+ List (Action resultType) -> Type
573+
574+``ST`` is a type level function which computes an appropriate ``STrans``
575+type given a list of *actions*, which describe transitions on resources.
576+An ``Action`` in a function type can take one of the following forms (plus
577+some others which we'll see later in the tutorial):
578+
579+* ``lbl ::: ty`` expresses that the resource ``lbl`` begins and ends in
580+ the state ``ty``
581+* ``lbl ::: ty_in :-> ty_out`` expresses that the resource ``lbl`` begins
582+ in state ``ty_in`` and ends in state ``ty_out``
583+* ``lbl ::: ty_in :-> (\res -> ty_out)`` expresses that the resource ``lbl``
584+ begins in state ``ty_in`` and ends in a state ``ty_out``, where ``ty_out``
585+ is computed from the result of the function ``res``.
586+
587+So, we can write some of the function types we've seen so far as follows:
588+
589+.. code-block:: idris
590+
591+ increment : (x : Var) -> ST m () [x ::: State Integer]
592+
593+That is, ``increment`` begins and ends with ``x`` in state ``State Integer``.
594+
595+.. code-block:: idris
596+
597+ makeAndIncrement : Integer -> ST m Integer []
598+
599+That is, ``makeAndIncrement`` begins and ends with no resources.
600+
601+.. code-block:: idris
602+
603+ addElement : (vec : Var) -> (item : a) ->
604+ ST m () [vec ::: State (Vect n a) :-> State (Vect (S n) a)]
605+
606+That is, ``addElement`` changes ``vec`` from ``State (Vect n a)`` to
607+``State (Vect (S n) a)``.
608+
609+.. code-block:: idris
610+
611+ readAndAdd : ConsoleIO io => (vec : Var) ->
612+ ST io Bool
613+ [vec ::: State (Vect n Integer) :->
614+ \res => State (if res then Vect (S n) Integer
615+ else Vect n Integer)]
616+
617+By writing the types in this way, we express the minimum necessary to explain
618+how each function affects the overall resource state. If there is a resource
619+update depending on a result, as with ``readAndAdd``, then we need to describe
620+it in full. Otherwise, as with ``increment`` and ``makeAndIncrement``, we can
621+write the input and output resource lists without repetition.
622+
623+An ``Action`` can also describe *adding* and *removing* states:
624+
625+* ``add ty``, assuming the operation returns a ``Var``, adds a new resource
626+ of type ``ty``.
627+* ``remove lbl ty`` expresses that the operation removes the resource named
628+ ``lbl``, beginning in state ``ty`` from the resource list.
629+
630+So, for example, we can write:
631+
632+.. code-block:: idris
633+
634+ newState : ST m Var [add (State Int)]

638+resource to the list with type ``State Int``. The second, ``removeState``,
639+given a label ``lbl``, removes the resource from the list. These types are

648+encounter some other ways using type level functions to help with readability.

650+In the remainder of this tutorial, we will generally use ``ST`` except on
