gulp-chug

A gulp plugin for running external gulpfiles as part of a gulp task inside another gulpfile.

gulp-chug is non-modifying, i.e., gulp-chug will return the same stream it receives. See Use with other plugins for an example.

Requires node >= 0.10

Inspired by shama's grunt-hub.

Note: This plugin has been blacklisted, however I have yet to find an example of a pattern that allows for the execution of child gulpfiles without task name collisions. If you have an example, let me know!

Install

Install with npm:

npm install gulp-chug

Usage

Run external gulpfiles

Run one external gulpfile:

var gulp = require( 'gulp' );
var chug = require( 'gulp-chug' );

gulp.task( 'default', function () {
    gulp.src( './subproj/gulpfile.js' )
        .pipe( chug() )
} );

Run multiple external gulpfiles:

var gulp = require( 'gulp' );
var chug = require( 'gulp-chug' );

gulp.task( 'default', function () {

    // Find and run all gulpfiles under all subdirectories
    gulp.src( './**/gulpfile.js' )
        .pipe( chug() )
} );

Use with other plugins

grunt-chug will not modify streams passed to it, but will happily accept streams modified by other plugins:

var gulp = require( 'gulp' );
var chug = require( 'gulp-chug' );
var replace = require( 'gulp-replace' );

gulp.task( 'default', function () {
    gulp.src( './subproj/gulpfile.js' )

        // Transform stream with gulp-replace
        .pipe( replace( 'Hello', 'Goodbye' ) )

        // Run modified stream with gulp-chug
        .pipe( chug() )
} );

Make gulp-chug faster by ignoring file contents

If gulp-chug is the only plugin in the stream, there's no need to actually read the contents of the gulpfiles. Set { read: false } in gulp.src to speed things up:

var gulp = require( 'gulp' );
var chug = require( 'gulp-chug' );

gulp.task( 'default', function () {
    gulp.src( './subproj/gulpfile.js', { read: false } )
        .pipe( chug() )
} );

Use child_process.spawn instead of child_process.exec for real-time child gulpfile output (see exec vs spawn)
