Package Exports

object-to-spawn-args

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (object-to-spawn-args) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

object-to-spawn-args

Converts an options object to an array suitable for passing to child_process.spawn().

Single letter object properties (e.g. c: "red") convert to short-option args (e.g. -c red). Longer object properties (e.g. colour: "red") convert to long-option args (e.g. --colour red). Object property values equalling true convert to flags (e.g. -l).

This options object:

var options = {
    l: true,
    c: "red",
    man: "pete",
    tramp: true
}

converts to

[ "-l", "-c", "red", "--man", "pete", "--tramp" ]

Installation

Move into your project directory then run:

$ npm install object-to-spawn-args --save

Mac / Linux users may need to run with sudo.

Usage

var toSpawnArgs = require("object-to-spawn-args");
var spawn = require("child_process").spawn;

var options = {
    l: true,
    a: true
};

spawn("ls", toSpawnArgs(options), { stdio: "inherit" });
