module Control.Monad.RWS.Lazy
mtl Control.Monad.RWS.Lazy
Lazy RWS monad. Inspired by the paper Functional Programming with Overloading and Higher-Order Polymorphism, Mark P Jones (http://web.cecs.pdx.edu/~mpj/) Advanced School of Functional Programming, 1995.
module Control.Monad.State.Lazy
mtl Control.Monad.State.Lazy
Lazy state monads. This module is inspired by the paper Functional Programming with Overloading and Higher-Order Polymorphism, Mark P Jones (http://web.cecs.pdx.edu/~mpj/) Advanced School of Functional Programming, 1995.
module Control.Monad.Trans.RWS.Lazy
transformers Control.Monad.Trans.RWS.Lazy
A monad transformer that combines ReaderT, WriterT and StateT. This version is lazy; for a strict version, see Control.Monad.Trans.RWS.Strict, which has the same interface.
module Control.Monad.Trans.State.Lazy
transformers Control.Monad.Trans.State.Lazy
Lazy state monads, passing an updatable state through a computation. See below for examples. In this version, sequencing of computations is lazy. For a strict version, see Control.Monad.Trans.State.Strict, which has the same interface. Some computations may not require the full power of state transformers: * For a read-only state, see Control.Monad.Trans.Reader. * To accumulate a value without using it on the way, see Control.Monad.Trans.Writer.
module Control.Monad.Trans.Writer.Lazy
transformers Control.Monad.Trans.Writer.Lazy
The lazy WriterT monad transformer, which adds collection of outputs (such as a count or string output) to a given monad. This version builds its output lazily; for a strict version, see Control.Monad.Trans.Writer.Strict, which has the same interface. This monad transformer provides only limited access to the output during the computation. For more general access, use Control.Monad.Trans.State instead.
module Control.Monad.Writer.Lazy
mtl Control.Monad.Writer.Lazy
Lazy writer monads. Inspired by the paper Functional Programming with Overloading and Higher-Order Polymorphism, Mark P Jones (http://web.cecs.pdx.edu/~mpj/pubs/springschool.html) Advanced School of Functional Programming, 1995.
module Data.ByteString.Lazy
bytestring Data.ByteString.Lazy
A time and space-efficient implementation of lazy byte vectors using lists of packed Word8 arrays, suitable for high performance use, both in terms of large data quantities, or high speed requirements. Lazy ByteStrings are encoded as lazy lists of strict chunks of bytes. A key feature of lazy ByteStrings is the means to manipulate large or unbounded streams of data without requiring the entire sequence to be resident in memory. To take advantage of this you have to write your functions in a lazy streaming style, e.g. classic pipeline composition. The default I/O chunk size is 32k, which should be good in most circumstances. Some operations, such as concat, append, reverse and cons, have better complexity than their Data.ByteString equivalents, due to optimisations resulting from the list spine structure. For other operations lazy ByteStrings are usually within a few percent of strict ones. The recomended way to assemble lazy ByteStrings from smaller parts is to use the builder monoid from Data.ByteString.Lazy.Builder. This module is intended to be imported qualified, to avoid name clashes with Prelude functions. eg. > import qualified Data.ByteString.Lazy as B Original GHC implementation by Bryan O'Sullivan. Rewritten to use UArray by Simon Marlow. Rewritten to support slices and use ForeignPtr by David Roundy. Rewritten again and extended by Don Stewart and Duncan Coutts. Lazy variant by Duncan Coutts and Don Stewart.
module Data.Text.Lazy
text Data.Text.Lazy
A time and space-efficient implementation of Unicode text using lists of packed arrays. Note: Read below the synopsis for important notes on the use of this module. The representation used by this module is suitable for high performance use and for streaming large quantities of data. It provides a means to manipulate a large body of text without requiring that the entire content be resident in memory. Some operations, such as concat, append, reverse and cons, have better time complexity than their Data.Text equivalents, due to the underlying representation being a list of chunks. For other operations, lazy Texts are usually within a few percent of strict ones, but often with better heap usage if used in a streaming fashion. For data larger than available memory, or if you have tight memory constraints, this module will be the only option. This module is intended to be imported qualified, to avoid name clashes with Prelude functions. eg. > import qualified Data.Text.Lazy as L
module Network.Socket.ByteString.Lazy
network Network.Socket.ByteString.Lazy
This module provides access to the BSD socket interface. This module is generally more efficient than the String based network functions in Socket. For detailed documentation, consult your favorite POSIX socket reference. All functions communicate failures by converting the error number to IOError. This module is made to be imported with Socket like so: > import Network.Socket hiding (send, sendTo, recv, recvFrom) > import Network.Socket.ByteString.Lazy > import Prelude hiding (getContents)
module Text.Parsec.ByteString.Lazy
parsec Text.Parsec.ByteString.Lazy
Make lazy ByteStrings an instance of Stream with Char token type.
module Text.Parsec.Text.Lazy
parsec Text.Parsec.Text.Lazy
Make Text an instance of Stream with Char token type.
module Text.Regex.Posix.ByteString.Lazy
regex-posix Text.Regex.Posix.ByteString.Lazy
This provides Lazy instances for RegexMaker and RegexLike based on Text.Regex.Posix.Wrap, and a (RegexContext Regex ByteString ByteString) instance. To use these instance, you would normally import Text.Regex.Posix. You only need to import this module to use the medium level API of the compile, regexec, and execute functions. All of these report error by returning Left values instead of undefined or error or fail. A Lazy ByteString with more than one chunk cannot be be passed to the library efficiently (as a pointer). It will have to converted via a full copy to a temporary normal bytestring (with a null byte appended if necessary).
package LazyVault
package
LazyVault is a sandboxing tool to install libraries and executables with a sandboxed environment. At the moment it's only supported under Unix or Gnu Systems. This package has only been tested under Gnu/Linux however. This program creates cabal sandboxes which you can use globally. For a detailed explaination on how this works refer to the README file found on the github page. Version 0.0.1
package lazy-csv
package
The CSV format is defined by RFC 4180. These efficient lazy parsers (String and ByteString variants) can report all CSV formatting errors, whilst also returning all the valid data, so the user can choose whether to continue, to show warnings, or to halt on error.  Valid fields retain information about their original location in the input, so a secondary parser from textual fields to typed values can give intelligent error messages. Version 0.5
package lazy-io
package
The library provides some basic but useful lazy IO functions. Keep in mind that lazy IO is generally discouraged. Perhaps a coroutine library (e.g. pipes) will better suit your needs. Version 0.1.0
package lazyarray
package
This package built on standard array package adds support for lazy monolithic arrays. Such arrays are lazy not only in their values, but in their indexes as well. Read the paper "Efficient Graph Algorithms Using Lazy Monolithic Arrays" (http://citeseer.ist.psu.edu/95126.html) for further details. Version 0.1.3
lazyBufferOp :: BufferOp ByteString
HTTP Network.BufferType
lazyBufferOp is the BufferOp definition over ByteStrings, the non-strict kind.
lazyByteString :: ByteString -> Builder
bytestring Data.ByteString.Builder
Create a Builder denoting the same sequence of bytes as a lazy ByteString. The Builder inserts large chunks of the lazy ByteString directly, but copies small ones to ensure that the generated chunks are large on average.
lazyByteStringCopy :: ByteString -> Builder
bytestring Data.ByteString.Builder.Extra
Construct a Builder that copies the lazy ByteString.
lazyByteStringHex :: ByteString -> Builder
bytestring Data.ByteString.Builder
Encode each byte of a lazy ByteString using its fixed-width hex encoding.
