There is a parent folder (gulp module) which has some child folders (gulp modules too). I want to run the default gulp task of each child through the gulpfile of the parent.

My approach was to iterate through the folders by using gulp-folders and run a gulp through gulp-shell by setting the current work directory to the corresponding child.

var tOptions = {};
[...]

gulp.task('setup-modules', folders('./', function(folder){
    tOptions.cwd = folder;
    gulp.start('setup-module');
    return gulp.src('', {read: false});
}));

gulp.task('setup-module', shell.task([
    'gulp'
], tOptions));

It seems that just one instance of the task setup-module gets started. What do I need to change to get several instances (for each child folder) of the task running?

Instead of using gulp-shell you can use gulp-chug and pass a glob to gulp.src() to access your child gulpfiles eliminating the need to iterate over each subdirectory. You can even specify which tasks you would like to run if you want to run any task(s) other than default.

Additionally, gulp-chug will do everything so there's no need to depend on more than just that one package accomplish what you're looking to do.

One of the examples from the gulp-chug docs goes over almost the exact scenario you're discussing.

gulpfile.js (parent)

// This example was taken from the gulp-chug docs

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() )
} );

  • Thank you, actually I was looking for something like `gulp-chug`. Just needed to change the wildcard (example parent called itself recursively). – Darkmiller May 26 '16 at 05:53
  • I've recognized that the `gulp.src` found all current 29 modules, but `chug` just executes about 16 of them. There is no error, just some node warnings when starting the 11th gulp task (`(node) warning: possible EventEmitter memory leak detected. 11 SIGINT listeners added. Use emitter.setMaxListeners() to increase limit.`) Any ideas why it stops after 16 modules? (I used the example, but replaced the string `'./**/gulpfile.js'` by `'./*/gulpfile.js'`). – Darkmiller May 26 '16 at 06:56
