Subprocess

Defined in subprocess@1.0.7

Values

namespace Subprocess

run_string

Type: Std::String -> Std::Array Std::String -> Std::String -> Std::IO::IOFail ((Std::String, Std::String), Subprocess::ExitStatus)

run_string(com, args, input) executes a command specified by com with arguments args, and writes input to the standard input of the running command.

The result is the pair of standard output and standard error, and an ExitStatus value.

run_with_stream

Type: Std::String -> Std::Array Std::String -> ((Std::IO::IOHandle, Std::IO::IOHandle, Std::IO::IOHandle) -> Std::IO::IOFail a) -> Std::IO::IOFail (a, Subprocess::ExitStatus)

run_with_stream(com, args, worker) executes a command specified by com with arguments args.

The function worker receives three IOHandles which are piped to the stdin, stdout and stderr of the running command.

The result is the value returned by worker paired with an ExitStatus value. - com : String: The path to the program to run. - args: Array String: The arguments to be passed to com. - worker : (IOHandle, IOHandle, IOHandle) -> IOFail a: Receives three IOHandles which are piped to stdin, stdout and stderr of the running command.

ExitStatus

Defined as: type ExitStatus = box union { ...variants... }

This type represents the exit status of a subprocess.

This type is the union of following variants:

  • exit : U8 - Means that the subprocess successfully exited (i.e., the main function returned or exit() was called) and stores the exit status code.
  • signaled : U8 - Means that the subprocess was terminated by a signal and stores the signal number which caused the termination.
  • wait_failed : () - Means that the run* function failed to wait the subprocess to exit.

WaitResult

Defined as: type WaitResult = box struct { ...fields... }
