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:

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

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.

13−-- * folds can be composed as a Tee but parsers cannot.

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−--

3−-- Module : Streamly.Data.ParserK
4−-- Copyright : (c) 2023 Composewell Technologies
5−-- License : BSD-3-Clause
6−-- Maintainer : streamly@composewell.com
7−-- Stability : pre-release
8−-- Portability : GHC
9−--
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−-- :}
84−--
85−-- == Experimental APIs
