Data.ListLike.IO

Description

String-like functions

Written by John Goerzen, jgoerzen@complete.org

Synopsis

Documentation

class ListLike full item => ListLikeIO full item | full -> item where #

An extension to ListLike for those data types that support I/O. These functions mirror those in System.IO for the most part. They also share the same names; see the comments in Data.ListLike for help importing them.

Note that some types may not be capable of lazy reading or writing. Therefore, the usual semantics of System.IO functions regarding laziness may or may not be available from a particular implementation.

Minimal complete definition:

  • hGetLine
  • hGetContents
  • hGet
  • hGetNonBlocking
  • hPutStr

Minimal complete definition

hGetLine, hGetContents, hGet, hGetNonBlocking, hPutStr

Methods

hGetLine :: Handle -> IO full #

Reads a line from the specified handle

hGetContents :: Handle -> IO full #

Read entire handle contents. May be done lazily like hGetContents.

hGet :: Handle -> Int -> IO full #

Read specified number of bytes. See hGet for particular semantics.

hGetNonBlocking :: Handle -> Int -> IO full #

Non-blocking read. See hGetNonBlocking for more.

hPutStr :: Handle -> full -> IO () #

Writing entire data.

hPutStrLn :: Handle -> full -> IO () #

Write data plus newline character.

getLine :: IO full #

Read one line

getContents :: IO full #

Read entire content from stdin. See hGetContents.

putStr :: full -> IO () #

Write data to stdout.

putStrLn :: full -> IO () #

Write data plus newline character to stdout.

interact :: (full -> full) -> IO () #

Interact with stdin and stdout by using a function to transform input to output. May be lazy. See interact for more.

readFile :: FilePath -> IO full #

Read file. May be lazy.

writeFile :: FilePath -> full -> IO () #

Write data to file.

appendFile :: FilePath -> full -> IO () #

Append data to file.
