Module V1.ProcessSource

Execute external programs.

Sourcetype result = {
  1. exit_code : int;
  2. stdout : string;
  3. stderr : string;
}
Sourceval run : t -> ?dir:string -> ?env:string list -> string -> string list -> result

run t prog args runs prog with arguments args and returns its exit status together with the content of stdout and stderr. The action is logged.

  • parameter dir

    change to dir before running the command.

  • parameter env

    specify additional environment variables as a list of the form NAME=VALUE.

Sourceval run_capture_exn : t -> ?dir:string -> ?env:string list -> string -> string list -> string

run_capture_exn t prog args same as run t prog args but returns stdout and die if the error code is nonzero or there is some output on stderr.

Sourceval run_ok : t -> ?dir:string -> ?env:string list -> string -> string list -> bool

run_ok t prog args same as run t prog args but only cares whether the execution terminated successfully (i.e., returned an error code of 0).
