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

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)

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

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:

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.
24+--
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.

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.

126−
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−--

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.
