class ProcessMaker a where Source

Instances

ProcessMaker CreateProcess Source

This is the usual maker argument to readCreateProcess.

ProcessMaker (CreateProcess, BufferMode, BufferMode) Source

Passing this to readCreateProcess as the maker argument allows you to set the buffer mode of the process stdout and stderr handles just after the handles are created. These are set to BlockBuffering by default, but for running console commands LineBuffering is probably what you want.

class ListLikeIO a c => ListLikeProcessIO a c where Source

Methods

forceOutput :: a -> IO a Source

readChunks :: Handle -> IO [a] Source

Read from a handle, returning a lazy list of the monoid a.

readProcessWithExitCode Source

Arguments

:: ListLikeProcessIO a c 
=> FilePath

command to run

-> [String]

any arguments

-> a

standard input

-> IO (ExitCode, a, a)

exitcode, stdout, stderr

Like readProcessWithExitCode, but with generalized input and output type.

readCreateProcessWithExitCode Source

Arguments

:: (ProcessMaker maker, ListLikeProcessIO a c) 
=> maker

command and arguments to run

-> a

standard input

-> IO (ExitCode, a, a)

exitcode, stdout, stderr

readCreateProcess :: (ProcessMaker maker, ProcessOutput a b, ListLikeProcessIO a c) => maker -> a -> IO b Source

readCreateProcessLazy :: (ProcessMaker maker, ProcessOutput a b, ListLikeProcessIO a c) => maker -> a -> IO b Source

Like readCreateProcess, but the output is read lazily.
