Module Ketrew_unix_process (.ml)

module Ketrew_unix_process: sig .. end

Manage calls to Unix processes

module Exit_code: sig .. end

Higher-level representation of Unix exit codes.

val exec : ?bin:string ->
       string list ->
       (string * string * Exit_code.t,
        [> `Process of [> `Exec of string * string list ] * [> `Exn of exn ] ])
       Ketrew_unix_io.Deferred_result.t

Execute a process with a given list of strings as “argv”, if you can provide the ~bin argument to specify the actual file to be executed. The function returns the tuple (stdout, stderr, exit_code).

val succeed : ?bin:string ->
       string list ->
       (string * string,
        [> `Process of
             [> `Exec of string * string list ] *
             [> `Exn of exn | `Non_zero of string ] ])
       Ketrew_unix_io.Deferred_result.t

Do like Ketrew_unix_process.exec but fail if the process does not exit with 0 status.

val error_to_string : [< `Process of
            [< `Exec of string * string list ] *
            [< `Exn of exn | `Non_zero of string ] ] ->
       string
