Documentation
data SystemProcess :: Effect where Source #
Low-level interface for a process, operating on raw chunks of bytes. Interface is modeled after System.Process.
ReadStdout :: SystemProcess m ByteString | Read a chunk from stdout. |
ReadStderr :: SystemProcess m ByteString | Read a chunk from stderr. |
WriteStdin :: ByteString -> SystemProcess m () | Write a |
Pid :: SystemProcess m Pid | Obtain the process ID. |
Signal :: Signal -> SystemProcess m () | Send a |
Wait :: SystemProcess m ExitCode | Wait for the process to terminate, returning its exit code. |
withSystemProcess :: forall param err r. Member (Scoped param (SystemProcess !! err)) r => param -> InterpreterFor (SystemProcess !! err) r Source #
Create a scoped resource for SystemProcess
.
The process configuration may depend on the provided value of type param
.
withSystemProcess_ :: forall err r. Member (Scoped_ (SystemProcess !! err)) r => InterpreterFor (SystemProcess !! err) r Source #
Create a scoped resource for SystemProcess
.
The process configuration is provided to the interpreter statically.
