1+# Changelog
2+
3+## 0.2.2 (Jan 2024)
4+
5+* Add fixities `infixr 5` for `cons` and `consM` functions.
6+* Fix a bug in Array `Eq` instance when the type is a sum type with
7+ differently sized constructors.
8+* lpackArraysChunksOf, compact, writeChunksWith, putChunksWith now take the
9+ buffer size in number of array elements instead of bytes.
10+
11+## 0.2.1 (Dec 2023)
12+
13+* Make the serialization of the unit constructor deterministic.
14+* Expose `pinnedSerialize` & `deserialize` via `Streamly.Data.Array`.
15+
16+## 0.2.0 (Nov 2023)
17+
18+See [0.1.0-0.2.0 API Changelog](https://github.com/composewell/streamly/blob/streamly-0.10.0/core/docs/ApiChangelogs/0.1.0-0.2.0.txt)
19+for a full list of API changes in this release. Only a few significant
20+changes are mentioned here.
21+
22+### Breaking Changes
23+
24+* `ParserK` in `Streamly.Data.ParserK` is not implicitly specialized
25+ to arrays anymore. To adapt to the new code, change `ParserK a m
26+ b` to `ParserK (Array a) m b` where the `Array` type comes from
27+ `Streamly.Data.Array`. This change also affected the signatures of
28+ `parseChunks` and `parseBreakChunks`.
29+* Changed the signature of 'Streamly.Data.Stream.handle' to make the
30+ exception handler monadic.
31+* Behavior change: Exceptions are now rethrown promptly in `bracketIO`.
32+
33+### Enhancements
34+
35+* __Serialization__: Added a `Streamly.Data.MutByteArray` module with a
36+ `Serialize` type class for fast binary serialization. The Data.Array
37+ module supplies the `serialize` and `deserialize` operations for arrays.
38+* __Unpinned Arrays__: Unboxed arrays are now created unpinned by default,
39+ they were created pinned earlier. During IO operations, unpinned arrays
40+ are automatically copied to pinned memory. When arrays are directly
41+ passed to IO operations programmers can choose to create them pinned to
42+ avoid a copy. To create pinned arrays, use the internal APIs with the
43+ `pinned*` prefix.
44+* StreamK now supports native exception handling routines (handle, bracketIO).
45+ Earlier we had to convert it to the `Stream` type for exception handling.
46+
47+### Deprecations
48+
49+See [0.1.0-0.2.0 API Changelog](https://github.com/composewell/streamly/blob/streamly-0.10.0/core/docs/ApiChangelogs/0.1.0-0.2.0.txt)
50+for a full list of deprecations.
51+
52+### Internal API Changes
53+
54+* Fold constructor has changed, added a `final` field to support
55+ finalization and cleanup of a chain of folds. The `extract` field is
56+ now used only for mapping the fold internal state to fold result for
57+ scanning purposes. If your fold does not require cleanup you can just use
58+ your existing `extract` function as `final` as well to adapt to this change.
59+* Many low level internal modules have been removed, they are entirely
60+ exported from higher level internal modules. If you were importing any
61+ of the missing low level modules then import the higher level modules instead.
62+* Internal module changes:
63+ * Streamly.Internal.Serialize.FromBytes -> Streamly.Internal.Data.Binary.Parser
64+ * Streamly.Internal.Serialize.ToBytes -> Streamly.Internal.Data.Binary.Stream
65+ * Streamly.Internal.Data.Unbox is now exported via Streamly.Internal.Data.Serialize
66+ * Streamly.Internal.Data.IORef.Unboxed is now exported via Streamly.Internal.Data.Serialize
67+
68+## 0.1.0 (March 2023)
69+
70+Also see [streamly-core-0.1.0 API Changelog](https://github.com/composewell/streamly/blob/streamly-0.10.0/core/docs/ApiChangelogs/0.1.0.txt) or
71+https://hackage.haskell.org/package/streamly-core-0.1.0/docs/docs/ApiChangelogs/0.1.0.txt
72+
73+`streamly` package is split into two packages, (1) `streamly-core` that
74+has only GHC boot library depdendecies, and (2) `streamly` that contains
75+higher level operations (including concurrent ones) with additional
76+dependencies.
77+
78+* Moved the following modules from `streamly` package to the
79+ `streamly-core` package:
80+ * Streamly.Console.Stdio
81+ * Streamly.Data.Fold
82+ * Streamly.Data.Unfold
83+ * Streamly.FileSystem.Handle
84+ * Streamly.Unicode.Stream
85+* Added the following new modules:
86+ * Streamly.Data.Array
87+ * Streamly.Data.Array.Generic
88+ * Streamly.Data.MutArray
89+ * Streamly.Data.MutArray.Generic
90+ * Streamly.Data.Parser

109+-- $overview
110+--
111+-- This module provides APIs to create and use unboxed immutable arrays. Once
112+-- created, their contents cannot be modified. Only types that are unboxable
113+-- via the 'Unbox' type class can be stored in these arrays. Note that the
114+-- array memory grows automatically when creating a new array, therefore, an
115+-- array can be created from a variable length stream.
116+--
117+-- == Folding Arrays
118+--
119+-- Convert array to stream, and fold the stream:
120+--
121+-- >>> fold f arr = Array.read arr & Stream.fold f
122+-- >>> fold Fold.sum (Array.fromList [1,2,3::Int])
123+-- 6
124+--
125+-- == Transforming Arrays
126+--
127+-- Convert array to stream, transform, and fold back to array:
128+--
129+-- >>> amap f arr = Array.read arr & fmap f & Stream.fold (Array.createOf (Array.length arr))
130+-- >>> amap (+1) (Array.fromList [1,2,3::Int])
131+-- fromList [2,3,4]
132+--
133+-- == Pinned and Unpinned Arrays
134+--
135+-- The array type can use both pinned and unpinned memory under the hood. The
136+-- default array creation operations create unpinned arrays. IO operations
137+-- automatically copy an array to pinned memory if the array passed to it is
138+-- unpinned. Programmers can use appropriate pinned array generation APIs to
139+-- reduce the copying if it happens.
140+--
141+-- Unpinned arrays have the advantage of allowing automatic defragmentation of
142+-- the memory by GC. Whereas pinned arrays have the advantage of not requiring
143+-- a copy by GC. Normally you would want to use unpinned arrays. However, in
144+-- some cases, for example, for long lived large data storage, and for
145+-- interfacing with the operating system or foreign (non-Haskell) consumers you
146+-- may want to use pinned arrays.
147+--
148+-- == Creating Arrays from Non-IO Streams
149+--
150+-- Array creation folds require 'MonadIO' otherwise the compiler may
151+-- incorrectly share the array memory thinking it is pure.
152+--
153+-- See the 'fromPureStream' unreleased API to generate an array from an
154+-- Identity stream safely without using MonadIO constraint.
155+--
156+-- Note that 'Identity' streams can be generalized to IO streams:
157+--
158+-- >>> stream = Stream.fromList [1,2,3] :: Stream Identity Int
159+-- >>> pure2IO s = Stream.morphInner (return . runIdentity) s :: Stream IO Int
160+-- >>> Stream.fold Array.create (pure2IO stream)
161+-- fromList [1,2,3]
162+--
163+-- == Programming Tips
164+--
165+-- This module is designed to be imported qualified:

12−-- This module provides immutable arrays in pinned memory (non GC memory)
13−-- suitable for long lived data storage, random access and for interfacing with
14−-- the operating system.
15−--
16−-- Arrays in this module are chunks of pinned memory that hold a sequence of
17−-- 'Storable' values of a given type, they cannot store non-serializable data
18−-- like functions. Once created an array cannot be modified. Pinned memory
19−-- allows efficient buffering of long lived data without adding any impact to
20−-- GC. One array is just one pointer visible to GC and it does not have to be
21−-- copied across generations. Moreover, pinned memory allows communication
22−-- with foreign consumers and producers (e.g. file or network IO) without
23−-- copying the data.

25−-- = Programmer Notes
26−--
27−-- Array creation APIs require a 'MonadIO' Monad, except 'fromList' which is a
28−-- pure API. To operate on streams in pure Monads like 'Identity' you can hoist
29−-- it to IO monad as follows:
30−--
31−-- >>> import Data.Functor.Identity (Identity, runIdentity)
32−-- >>> s = Stream.fromList [1..10] :: SerialT Identity Int
33−-- >>> s1 = Stream.hoist (return . runIdentity) s :: SerialT IO Int
34−-- >>> Stream.fold Array.write s1 :: IO (Array Int)
35−-- [1,2,3,4,5,6,7,8,9,10]
36−--
37−-- 'unsafePerformIO' can be used to get a pure API from IO, as long as you know
38−-- it is safe to do so:
39−--
40−-- >>> import System.IO.Unsafe (unsafePerformIO)
41−-- >>> unsafePerformIO $ Stream.fold Array.write s1 :: Array Int
42−-- [1,2,3,4,5,6,7,8,9,10]
43−--
44−-- To apply a transformation to an array use 'read' to unfold the array into a
45−-- stream, apply a transformation on the stream and then use 'write' to fold it
46−-- back to an array.

147+-- == Fusion Limitations
148+--
149+-- Folds support stream fusion for generating loops comparable to the speed of
150+-- C. However, it has some limitations. For fusion to work, the folds must be
151+-- inlined, folds must be statically known and not generated dynamically, folds
152+-- should not be passed recursively.
153+--
154+-- Another limitation is due to the quadratic complexity causing slowdown when
155+-- too many nested compositions are used. Especially, the performance of the
156+-- Applicative instance and splitting operations (e.g. 'splitWith') degrades
157+-- quadratically (O(n^2)) when combined @n@ times, roughly 8 or less sequenced
158+-- operations are fine. For these cases folds can be converted to parsers and
159+-- then used as ParserK.

5+-- Maintainer : streamly@composewell.com
6+-- Portability : GHC
7+--
8+-- A low level byte Array type 'MutByteArray', along with type classes 'Unbox'
9+-- and 'Serialize' for fast binary serialization and deserialization of Haskell
10+-- values. Serialization, deserialization performance is similar to, and in
11+-- some cases many times better than the store package. Conceptually, the
12+-- 'Serialize' type class works in the same way as store.
13+--
14+-- Serialize instances are configurable to use constructor names (see
15+-- 'Streamly.Internal.Data.MutByteArray.encodeConstrNames'), record field names (see
16+-- 'Streamly.Internal.Data.MutByteArray.encodeRecordFields') instead of binary
17+-- encoded values. This is an experimental feature which allows JSON like
18+-- properties with faster speed. For example, you can change the order of
19+-- constructors or record fields without affecting serialized value.
20+--
21+-- Higher level unboxed array modules "Streamly.Data.Array" and
22+-- "Streamly.Data.MutArray" are built on top of this module. Unboxed arrays are
23+-- essentially serialized Haskell values. Array modules provide higher level
24+-- serialization routines like 'Streamly.Internal.Data.Array.pinnedSerialize'
25+-- and 'Streamly.Internal.Data.Array.deserialize' from the
26+-- "Streamly.Internal.Data.Array" module.
27+--
28+-- == Mutable Byte Array
29+--
30+-- 'MutByteArray' is a primitive mutable array in the IO monad. 'Unbox' and
31+-- 'Serialize' type classes use this primitive array to serialize data to and
32+-- deserialize it from. This array is used to build higher level unboxed
33+-- array types 'Streamly.Data.MutArray.MutArray' and 'Streamly.Data.Array.Array'.
34+--
35+-- == Using Unbox
36+--
37+-- The 'Unbox' type class is simple and used to serialize non-recursive fixed
38+-- size data types. This type class is primarily used to implement unboxed
39+-- arrays. Unboxed arrays are just a sequence of serialized fixed length
40+-- Haskell data types. Instances of this type class can be derived using
41+-- 'Generic' or template haskell based deriving functions provided in this
42+-- module.
43+--
44+-- Writing a data type to an array using the array creation routines in
45+-- "Streamly.Data.Array" or "Streamly.Data.MutArray" (e.g. @writeN@ or
46+-- @fromListN@), serializes the type to the array. Similarly, reading the data
47+-- type from the array deserializes it. You can also serialize and deserialize
48+-- directly to and from a 'MutByteArray', using the type class methods.
49+--
50+-- == Using Serialize
51+--
52+-- The 'Serialize' type class is a superset of the 'Unbox' type class, it can
53+-- serialize variable length data types as well e.g. Haskell lists. Use
54+-- 'deriveSerialize' to derive the instances of the type class automatically
55+-- and then use the type class methods to serialize and deserialize to and from
56+-- a 'MutByteArray'.
57+--
58+-- See 'Streamly.Internal.Data.Array.pinnedSerialize' and
59+-- 'Streamly.Internal.Data.Array.deserialize' for 'Array' type based
60+-- serialization.
61+--
62+-- == Comparing serialized values
63+--
64+-- When using the `Unbox` type class the same value may result in differing
65+-- serialized bytes because of unused uninitialized data in case of sum types.
66+-- Therefore, byte comparison of serialized values is not reliable.
67+--
68+-- However, the 'Serialize' type class guarantees that the serialized values
69+-- are always exactly the same and byte comparison of serialized is reliable.

10+-- Parsers are stream consumers like folds with the following differences:
11+--
12+-- * folds cannot fail but parsers can fail and backtrack.
13+-- * folds can be composed as a Tee but parsers cannot.
14+-- * folds can be used for scanning but parsers cannot.
15+-- * folds can be converted to parsers.
16+--
17+-- This module implements parsers with stream fusion which compile to efficient
18+-- loops comparable to the speed of C.
19+--
20+-- == Using Parsers
21+--
22+-- This module provides elementary parsers and parser combinators that can be
23+-- used to parse a stream of data. Additionally, all the folds from the
24+-- "Streamly.Data.Fold" module can be converted to parsers using 'fromFold'.
25+-- All the parsing functionality provided by popular parsing libraries, and
26+-- more is available. Also see "Streamly.Unicode.Parser" module for Char stream
27+-- parsers.
28+--
29+-- A data stream can be transformed to a stream of parsed data elements. Parser
30+-- combinators can be used to create a pipeline of folds or parsers such that
31+-- the next fold or parser consumes the result of the previous parser. See
32+-- 'Streamly.Data.Stream.parse' and 'Streamly.Data.Stream.parseMany' to run
33+-- these parsers on a stream.
34+--
35+-- == Parser vs ParserK
36+--
37+-- There are two functionally equivalent parsing modules,
38+-- "Streamly.Data.Parser" (this module) and "Streamly.Data.ParserK". The latter
39+-- is a CPS based wrapper over the former, and can be used for parsing in
40+-- general. "Streamly.Data.Parser" enables stream fusion and should be
41+-- preferred over "Streamly.Data.ParserK" for high performance stream parsing
42+-- use cases. However, there are a few cases where this module is not
43+-- suitable and ParserK should be used instead.
44+--
45+-- For static fusion, parser combinators have to use strict pattern matching on
46+-- arguments of type Parser. This leads to infinte loop when a parser is
47+-- defined recursively, due to strict evaluation of the recursive call. For
48+-- example, the following implementation loops infinitely because of the
49+-- recursive use of parser @p@ in the @*>@ combinator:
50+--
51+-- >>> import Streamly.Data.Parser (Parser)
52+-- >>> import qualified Streamly.Data.Fold as Fold
53+-- >>> import qualified Streamly.Data.Parser as Parser
54+-- >>> import qualified Streamly.Data.Stream as Stream
55+-- >>> import Control.Applicative ((<|>))
56+--
57+-- >>> :{
58+-- >>> p :: Monad m => Parser Char m String
59+-- >>> p = Parser.satisfy (== '(') *> p <|> Parser.fromFold Fold.toList
60+-- >>> :}
61+--
62+-- Use ParserK when recursive use is required:
63+--
64+-- >>> import Streamly.Data.ParserK (ParserK)
65+-- >>> import qualified Streamly.Data.StreamK as StreamK
66+-- >>> import qualified Streamly.Internal.Data.StreamK as StreamK (parse)
67+-- >>> import qualified Streamly.Internal.Data.ParserK as ParserK (adapt)
68+--
69+-- >>> :{
70+-- >>> p :: Monad m => ParserK Char m String
71+-- >>> p = ParserK.adapt (Parser.satisfy (== '(')) *> p <|> ParserK.adapt (Parser.fromFold Fold.toList)
72+-- >>> :}
73+--
74+-- >>> StreamK.parse p $ StreamK.fromStream $ Stream.fromList "hello"
75+-- Right "hello"
76+--
77+-- For this reason Applicative, Alternative or Monad compositions with
78+-- recursion cannot be used with the 'Parser' type. Alternative type class based
79+-- operations like 'asum' and Alternative based generic parser combinators use
80+-- recursion. Similarly, Applicative type class based operations like
81+-- 'Prelude.sequence' use recursion. Custom implementations of many such
82+-- operations are provided in this module (e.g. 'some', 'many'), and those
83+-- should be used instead.
84+--
85+-- Another limitation of Parser type is due to the quadratic complexity causing
86+-- slowdown when too many nested compositions are used. Especially Applicative,
87+-- Monad, Alternative instances, and sequenced parsing operations (e.g. nested
88+-- 'one', and 'splitWith') degrade the performance quadratically (O(n^2)) when
89+-- combined @n@ times, roughly 8 or less sequenced parsers are fine. READ THE
90+-- DOCS OF APPLICATIVE, MONAD AND ALTERNATIVE INSTANCES.
91+--
92+-- == Streaming Parsers
93+--
94+-- With 'Streamly.Data.ParserK.ParserK' you can use the generic Alternative
95+-- type class based parsers from the
96+-- <https://hackage.haskell.org/package/parser-combinators parser-combinators>
97+-- library or similar. However, we recommend that you use the equivalent
98+-- functionality from this module for better performance and for streaming
99+-- behavior.
100+--
101+-- Firstly, the combinators in this module are faster due to stream fusion.
102+-- Secondly, these are streaming in nature as the results can be passed
103+-- directly to other stream consumers (folds or parsers). The Alternative type
104+-- class based parsers would end up buffering all the results in lists before
105+-- they can be consumed.
106+--
107+-- When recursion or heavy nesting is needed use ParserK.
108+--
109+-- == Error Reporting
110+--
111+-- These parsers do not report the error context (e.g. line number or column).
112+-- This may be supported in future.
113+--
114+-- == Monad Transformer Stack
115+--
116+-- 'MonadTrans' instance is not provided. If the 'Parser' type is the top most
117+-- layer (which should be the case almost always) you can just use 'fromEffect'
118+-- to execute the lower layer monad effects.
119+--
120+-- == Parser vs ParserK Implementation
121+--
122+-- The 'Parser' type represents a stream consumer by composing state as data
123+-- which enables stream fusion. Stream fusion generates a tight loop without
124+-- any constructor allocations between the stages, providing C like performance
125+-- for the loop. Stream fusion works when multiple functions are combined in a
126+-- pipeline statically. Therefore, the operations in this module must be
127+-- inlined and must not be used recursively to allow for stream fusion.
128+--
129+-- The 'ParserK' type represents a stream consumer by composing function calls,
130+-- therefore, a function call overhead is incurred at each composition. It is
131+-- quite fast in general but may be a few times slower than a fused parser.
132+-- However, it allows for scalable dynamic composition especially parsers can
133+-- be used in recursive calls. Using the 'ParserK' type operations like
134+-- 'splitWith' provide linear (O(n)) performance with respect to the number of
135+-- compositions.
136+--

140+-- yet been released.

7+-- Stability : pre-release

10+-- See the general notes about parsing in the "Streamly.Data.Parser" module.
11+-- This module implements a using Continuation Passing Style (CPS) wrapper over
12+-- the "Streamly.Data.Parser" module. It is as fast or faster than attoparsec.
13+--
14+-- == Parser vs ParserK
15+--
16+-- 'ParserK' is preferred over 'Streamly.Data.Parser.Parser' when extensive
17+-- applicative, alternative and monadic composition is required, or when
18+-- recursive or dynamic composition of parsers is required. The
19+-- 'Streamly.Data.Parser.Parser' type fuses statically and creates efficient
20+-- loops whereas 'ParserK' uses function call based composition and has
21+-- comparatively larger runtime overhead but it is better suited to the
22+-- specific use cases mentioned above. 'ParserK' also allows to efficient parse
23+-- a stream of arrays, it can also break the input stream into a parse result
24+-- and remaining stream so that the stream can be parsed independently in
25+-- segments.
26+--
27+-- == Using ParserK
28+--
29+-- All the parsers from the "Streamly.Data.Parser" module can be adapted to
30+-- ParserK using the 'Streamly.Data.ParserK.adaptC',
31+-- 'Streamly.Internal.Data.ParserK.adapt', and
32+-- 'Streamly.Internal.Data.ParserK.adaptCG' combinators.
33+--
34+-- 'Streamly.Data.StreamK.parseChunks' runs a parser on a stream of unboxed
35+-- arrays, this is the preferred and most efficient way to parse chunked input.
36+-- The more general 'Streamly.Data.StreamK.parseBreakChunks' function returns
37+-- the remaining stream as well along with the parse result. There are
38+-- 'Streamly.Internal.Data.StreamK.parseChunksGeneric',
39+-- 'Streamly.Internal.Data.StreamK.parseBreakChunksGeneric' as well to run
40+-- parsers on boxed arrays. 'Streamly.Internal.Data.StreamK.parse',
41+-- 'Streamly.Internal.Data.StreamK.parseBreak' run parsers on a stream of
42+-- individual elements instead of stream of arrays.
43+--
44+-- == Monadic Composition
45+--
46+-- Monad composition can be used for lookbehind parsers, we can dynamically
47+-- compose new parsers based on the results of the previously parsed values.
48+--
49+-- If we have to parse "a9" or "9a" but not "99" or "aa" we can use the
50+-- following non-monadic, backtracking parser:
51+--
52+-- >>> digits p1 p2 = ((:) <$> p1 <*> ((:) <$> p2 <*> pure []))
53+-- >>> :{
54+-- backtracking :: Monad m => ParserK Char m String
55+-- backtracking = ParserK.adapt $
56+-- digits (Parser.satisfy isDigit) (Parser.satisfy isAlpha)
57+-- <|>
58+-- digits (Parser.satisfy isAlpha) (Parser.satisfy isDigit)
59+-- :}
60+--
61+-- We know that if the first parse resulted in a digit at the first place then
62+-- the second parse is going to fail. However, we waste that information and
63+-- parse the first character again in the second parse only to know that it is
64+-- not an alphabetic char. By using lookbehind in a 'Monad' composition we can
65+-- avoid redundant work:
66+--
67+-- >>> data DigitOrAlpha = Digit Char | Alpha Char
68+--
69+-- >>> :{
70+-- lookbehind :: Monad m => ParserK Char m String
71+-- lookbehind = do
72+-- x1 <- ParserK.adapt $
73+-- Digit <$> Parser.satisfy isDigit
74+-- <|> Alpha <$> Parser.satisfy isAlpha
75+-- -- Note: the parse depends on what we parsed already
76+-- x2 <- ParserK.adapt $
77+-- case x1 of
78+-- Digit _ -> Parser.satisfy isAlpha
79+-- Alpha _ -> Parser.satisfy isDigit
80+-- return $ case x1 of
81+-- Digit x -> [x,x2]
82+-- Alpha x -> [x,x2]
83+-- :}

127+-- EXPLANATION: In imperative terms a fold can be considered as a loop over the stream
128+-- that reduces the stream to a single value.
129+-- Left and right folds both use a fold function @f@ and an identity element
130+-- @z@ (@zero@) to deconstruct a recursive data structure and reconstruct a
131+-- new data structure. The new structure may be a recursive construction (a
132+-- container) or a non-recursive single value reduction of the original
133+-- structure.
134+--
135+-- Both right and left folds are mathematical duals of each other, they are
136+-- functionally equivalent. Operationally, a left fold on a left associated
137+-- structure behaves exactly in the same way as a right fold on a right
138+-- associated structure. Similarly, a left fold on a right associated structure
139+-- behaves in the same way as a right fold on a left associated structure.
140+-- However, the behavior of a right fold on a right associated structure is
141+-- operationally different (even though functionally equivalent) than a left
142+-- fold on the same structure.
143+--
144+-- On right associated structures like Haskell @cons@ lists or Streamly
145+-- streams, a lazy right fold is naturally suitable for lazy recursive
146+-- reconstruction of a new structure, while a strict left fold is naturally
147+-- suitable for efficient reduction. In right folds control is in the hand of
148+-- the @puller@ whereas in left folds the control is in the hand of the
149+-- @pusher@.
150+--
151+-- The behavior of right and left folds are described in detail in the
152+-- individual fold's documentation. To illustrate the two folds for right
153+-- associated @cons@ lists:
154+--
155+-- > foldr :: (a -> b -> b) -> b -> [a] -> b
156+-- > foldr f z [] = z
157+-- > foldr f z (x:xs) = x `f` foldr f z xs
158+-- >
159+-- > foldl :: (b -> a -> b) -> b -> [a] -> b
160+-- > foldl f z [] = z
161+-- > foldl f z (x:xs) = foldl f (z `f` x) xs
162+--
163+-- @foldr@ is conceptually equivalent to:
164+--
165+-- > foldr f z [] = z
166+-- > foldr f z [x] = f x z
167+-- > foldr f z xs = foldr f (foldr f z (tail xs)) [head xs]
168+--
169+-- @foldl@ is conceptually equivalent to:
170+--
171+-- > foldl f z [] = z
172+-- > foldl f z [x] = f z x
173+-- > foldl f z xs = foldl f (foldl f z (init xs)) [last xs]
174+--
175+-- Left and right folds are duals of each other.
176+--
177+-- @
178+-- foldr f z xs = foldl (flip f) z (reverse xs)
179+-- foldl f z xs = foldr (flip f) z (reverse xs)
180+-- @
181+--
182+-- More generally:
183+--
184+-- @
185+-- foldr f z xs = foldl g id xs z where g k x = k . f x
186+-- foldl f z xs = foldr g id xs z where g x k = k . flip f x
187+-- @
188+--
189+
190+-- NOTE: Folds are inherently serial as each step needs to use the result of
191+-- the previous step. However, it is possible to fold parts of the stream in
192+-- parallel and then combine the results using a monoid.

642+-- $overview
643+--
644+-- Streamly is a framework for modular data flow based programming and
645+-- declarative concurrency. Powerful stream fusion framework in streamly
646+-- allows high performance combinatorial programming even when using byte level
647+-- streams. Streamly API is similar to Haskell lists.
648+--
649+-- == Console Echo Example
650+--
651+-- In the following example, 'repeatM' generates an infinite stream of 'String'
652+-- by repeatedly performing the 'getLine' IO action. 'mapM' then applies
653+-- 'putStrLn' on each element in the stream converting it to stream of '()'.
654+-- Finally, 'drain' folds the stream to IO discarding the () values, thus
655+-- producing only effects.
656+--
657+-- >>> import Data.Function ((&))
658+--
659+-- >>> :{
660+-- echo =
661+-- Stream.repeatM getLine -- Stream IO String
662+-- & Stream.mapM putStrLn -- Stream IO ()
663+-- & Stream.fold Fold.drain -- IO ()
664+-- :}
665+--
666+-- This is a console echo program. It is an example of a declarative loop
667+-- written using streaming combinators. Compare it with an imperative @while@
668+-- loop.
669+--
670+-- Hopefully, this gives you an idea how we can program declaratively by
671+-- representing loops using streams. In this module, you can find all
672+-- "Data.List" like functions and many more powerful combinators to perform
673+-- common programming tasks.
674+--
675+-- == Stream Fusion
676+--
677+-- The fused 'Stream' type in this module employs stream fusion for C-like
678+-- performance when looping over data. It represents the stream as a state
679+-- machine using an explicit state, and a step function working on the state. A
680+-- typical stream operation consumes elements from the previous state machine
681+-- in a stream pipeline, transforms the elements and yields new values for the
682+-- next stage to consume. The stream operations are modular and represent a
683+-- single task, they have no knowledge of previous or next operation on the
684+-- elements.
685+--
686+-- A typical stream pipeline consists of a stream producer, several stream
687+-- transformation operations and a stream consumer. All these operations taken
688+-- together form a closed loop processing the stream elements. Elements are
689+-- transferred between stages using a boxed data constructor. However, all the
690+-- stages of the pipeline are fused together by GHC, eliminating the boxing of
691+-- intermediate constructors, and thus forming a tight C like loop without any
692+-- boxed data being used in the loop.
693+--
694+-- Stream fusion works effectively when:
695+--
696+-- * the stream pipeline is composed statically (known at compile time)
697+-- * all the operations forming the loop are inlined
698+-- * the loop is not recursively defined, recursion breaks inlining
699+--
700+-- If these conditions cannot be met, the CPS style stream type 'StreamK' may
701+-- turn out to be a better choice than the fused stream type 'Stream'.
702+--
703+-- == Stream vs StreamK
704+--
705+-- The fused stream model avoids constructor allocations and function call
706+-- overheads. However, the stream is represented as a state machine, and to
707+-- generate stream elements it has to navigate the decision tree of the state
708+-- machine. Moreover, the state machine is cranked for each element in the
709+-- stream. This performs extremely well when the number of states are limited.
710+-- The state machine starts getting expensive as the number of states increase.
711+-- For example, generating a stream from a list requires a single state and is
712+-- very efficient, even if it has millions of elements. However, using 'cons'
713+-- to construct a million element stream would be a disaster.
714+--
715+-- A typical worst case scenario for fused stream model is a large number of
716+-- `cons` or `append` operations. A few static `cons` or `append` operations
717+-- are very fast and much faster than a CPS style stream because CPS involves a
718+-- function call for each element whereas fused stream involves a few
719+-- conditional branches in the state machine. However, constructing a large
720+-- stream using `cons` introduces as many states in the state machine as the
721+-- number of elements. If we compose `cons` as a balanced binary tree it will
722+-- take @n * log n@ time to navigate the tree, and @n * n@ if it is a right
723+-- associative composition.
724+--
725+-- Operations like 'cons' or 'append'; are typically recursively called to
726+-- construct a lazy infinite stream. For such use cases the CPS style 'StreamK'
727+-- should be used. CPS streams do not have a state machine that needs to be
728+-- cranked for each element, past state has no effect on the future element
729+-- processing. However, CPS incurs a function call overhead for each element
730+-- processed, the overhead could be large compared to a fused state machine
731+-- even if it has many states. However, because of its linear performance
732+-- characterstics, after a certain threshold of stream compositions the CPS
733+-- stream would perform much better than the quadratic fused stream operations.
734+--
735+-- As a general guideline, you need to use 'StreamK' when you have to use
736+-- 'cons', 'append' or other operations having quadratic complexity at a large
737+-- scale. Typically, in such cases you need to compose the stream recursively,
738+-- by calling an operation in a loop. The decision to compose the stream is
739+-- taken at run time rather than statically at compile time.
740+--
741+-- Typically you would compose a 'StreamK' of chunks of data so that the
742+-- StreamK overhead is not high, and then process the chunks using 'Stream' by
743+-- using statically fused stream pipeline operations on the chunks.
744+--
745+-- 'Stream' and 'StreamK' types can be interconverted. See
746+-- "Streamly.Data.StreamK" module for conversion operations.

15+-- Unlike the statically fused operations in "Streamly.Data.Stream", StreamK

104+-- $overview
105+--
106+-- An 'Unfold' is a source or a producer of a stream of values. It takes a
107+-- seed value as an input and unfolds it into a sequence of values.
108+--
109+-- For example, the 'fromList' Unfold generates a stream of values from a
110+-- supplied list. Unfolds can be converted to 'Streamly.Internal.Data.Stream'
111+-- using the 'Stream.unfold' operation.
112+--
113+-- >>> stream = Stream.unfold Unfold.fromList [1..100]
114+-- >>> Stream.fold Fold.sum stream
115+-- 5050
116+--
117+-- The input seed of an unfold can be transformed using 'lmap':
118+--
119+-- >>> u = Unfold.lmap (fmap (+1)) Unfold.fromList
120+-- >>> Stream.fold Fold.toList $ Stream.unfold u [1..5]
121+-- [2,3,4,5,6]
122+--
123+-- Output stream of an 'Unfold' can be transformed using transformation
124+-- combinators. For example, to retain only the first two elements of an
125+-- unfold:
126+--
127+-- >>> u = Unfold.take 2 Unfold.fromList
128+-- >>> Stream.fold Fold.toList $ Stream.unfold u [1..100]
129+-- [1,2]
130+--
131+-- Unfolds can be nested efficiently. For example, to implement nested looping:
132+--
133+-- >>> u1 = Unfold.lmap fst Unfold.fromList
134+-- >>> u2 = Unfold.lmap snd Unfold.fromList
135+-- >>> u = Unfold.crossWith (,) u1 u2
136+-- >>> Stream.fold Fold.toList $ Stream.unfold u ([1,2,3], [4,5,6])
137+-- [(1,4),(1,5),(1,6),(2,4),(2,5),(2,6),(3,4),(3,5),(3,6)]
138+--
139+-- 'Unfold' @u1@ generates a stream from the first list in the input tuple,
140+-- @u2@ generates another stream from the second list. The combines 'Unfold'
141+-- @u@ nests the two streams i.e. for each element in first stream, for each
142+-- element in second stream apply the supplied function (i.e. @(,)@) to the
143+-- pair of elements.
144+--
145+-- This is the equivalent of the nested looping construct from imperative
146+-- languages, also known as the cross product of two streams in functional
147+-- parlance.
148+--
149+-- Please see "Streamly.Internal.Data.Unfold" for additional @Pre-release@
150+-- functions.
151+--
152+-- == Creating New Unfolds
153+--
154+-- There are many commonly used unfolds provided in this module. However, you
155+-- can always create your own as well. An 'Unfold' is just a data
156+-- representation of a stream generator function. It consists of an @inject@
157+-- function which covnerts the supplied seed into an internal state of the
158+-- unfold, and a @step@ function which takes the state and generates the next
159+-- output in the stream. For those familiar with the list "Data.List.unfoldr"
160+-- function, this is a data representation of the same.
161+--
162+-- Smart constructor functions are provided in this module for constructing new
163+-- 'Unfolds'. For example, you can use the 'Unfold.unfoldr' constructor to
164+-- create an 'Unfold' from a pure step function, unfoldr uses 'id' as the
165+-- @inject@ function.
166+--
167+-- Let's define a simple pure step function:
168+--
169+-- >>> :{
170+-- f [] = Nothing
171+-- f (x:xs) = Just (x, xs)
172+-- :}
173+--
174+-- Create an 'Unfold' from the step function:
175+--
176+-- >>> u = Unfold.unfoldr f
177+--
178+-- Run the 'Unfold':
179+--
180+-- >>> Stream.fold Fold.toList $ Stream.unfold u [1,2,3]
181+-- [1,2,3]
182+--
183+-- The 'Unfold.unfoldr' smart constructor is essentially the same as the list
184+-- "Data.List.unfoldr" function. We can use the same step function in both::
185+--
186+-- >>> Data.List.unfoldr f [1,2,3]
187+-- [1,2,3]
188+--
189+-- == Unfolds vs. Streams
190+--
191+-- The 'Unfold' abstraction for representing streams was introduced in Streamly
192+-- to provide C like performance for nested looping of streams. 'Unfold' and
193+-- 'Stream' abstractions are similar with the following differences:
194+--
195+-- * 'Stream' is less efficient than 'Unfold' for nesting.
196+-- * 'Stream' is more powerful than 'Unfold'.
197+-- * 'Stream' API is more convenient for programming
198+--
199+-- Unfolds can be easily converted to streams using 'Stream.unfold', however,
200+-- vice versa is not possible. To provide a familiar analogy, 'Unfold' is to
201+-- 'Stream' as 'Applicative' is to 'Monad'.
202+--
203+-- To demonstrate the efficiency of unfolds, the nested loop example in the
204+-- previous section can be implemented with concatMap or Monad instance of
205+-- streams as follows:
206+--
207+-- @
208+-- do
209+-- x <- Stream.unfold Unfold.fromList [1,2,3]
210+-- y <- Stream.unfold Unfold.fromList [4,5,6]
211+-- return (x, y)
212+-- @
213+--
214+-- As you can see, this is more convenient to write than using the 'crossWith'
215+-- unfold combinator. However, this turns out to be many times slower than the
216+-- unfold implementation. The Unfold version is equivalent in performance to
217+-- the C implementation of the same nested loop. Similarly, unfolds can be
218+-- nested with streams using the 'unfoldMany' combinator which is a much more
219+-- efficient alternative to the 'concatMap' operation.
220+--
221+-- Streams use a hybrid implementation approach using direct style as well as
222+-- CPS. Unfolds do not use CPS, therefore, lack the power that is afforded to
223+-- streams by CPS. The CPS implementation allows infinitely scalable @cons@ and
224+-- @append@ operations in streams. It is also used to implement concurrency in
225+-- streams.
226+--
227+-- To summarize, unfolds are a high performance solution to the nesting
228+-- problem. Since streams provide a more palatable API for programming, work
229+-- with streams unless you need unfolds for better performance in nesting
230+-- situations. There is little difference in the way in which unfolds and
231+-- streams are written, it is easy to adapt a stream to an unfold. If you are
232+-- writing an unfold you can convert it to stream for free using
233+-- 'Stream.unfold'.
