Re-export all symbols and instances of the process-extras package. Adds the Chunk type with a ProcessOutput instance, and a collectOutput function to turn a list of chunks into any instance of ProcessOutput, such as (ExitCode, String, String). This means you can have readCreateProcess output a list of Chunk, operate on it to do progress reporting, and finally convert it to the type that readProcessWithExitCode woud have returned.

readCreateProcessLazy :: (ProcessMaker maker, ProcessOutput a b, ListLikeProcessIO a c) => maker -> a -> IO b Source
Like readCreateProcess, but the output is read lazily.
readCreateProcessWithExitCode Source

=> maker | command and arguments to run |
-> a | standard input |
-> IO (ExitCode, a, a) | exitcode, stdout, stderr |

:: 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.
This type is a concrete representation of the methods of class ProcessOutput. If you take your process output as this type you could, for example, echo all the output and then use collectOutput below to convert it to any other instance of ProcessOutput.
ProcessHandle ProcessHandle | This will always come first, before any output or exit code. |
Stdout a | |
Stderr a | |
Result ExitCode | |
Exception SomeException | Note that the instances below do not use this constructor. |
ListLikeProcessIO a c => ProcessOutput a [Chunk a] | |
ListLikeProcessIO a c => ProcessOutput a (ExitCode, [Chunk a]) |
collectOutput :: ProcessOutput a b => [Chunk a] -> b Source
Turn a [Chunk a]
into any other instance of ProcessOutput
