Methods
forceOutput :: a -> IO a Source

class Monoid b => ProcessOutput a b | b -> a where Source
Instances
| ListLikeProcessIO a c => ProcessOutput a [Chunk a] | |
| ListLikeProcessIO a c => ProcessOutput a (ExitCode, [Chunk a]) | |
| ListLikeProcessIO a c => ProcessOutput a (ExitCode, a, a) |
readCreateProcess :: (ProcessOutput a b, ListLikeProcessIO a c) => CreateProcess -> a -> IO b Source
readCreateProcessLazy :: (ProcessOutput a b, ListLikeProcessIO a c) => CreateProcess -> a -> IO b Source
Like readCreateProcess, but the output is read lazily.
readCreateProcessWithExitCode Source
Arguments
| :: ListLikeProcessIO a c | |
| => CreateProcess | command and arguments to run |
| -> a | standard input |
| -> IO (ExitCode, a, a) | exitcode, stdout, stderr |
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.
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.
Constructors
| 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. |
Instances
| 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.
showCreateProcessForUser :: CreateProcess -> String Source
System.Process utility functions.
