Gulp Equivalent (from Grunt) - Multiple src files

Question

I've been tinkering around with GulpJS and believe it's a good next step from Grunt, but am having a few issues with the syntax in comparison.

Here is a section from my Gruntfile.js:

concat: {
    ie: {
        options: {
            separator: "\n\n"
        },
        src: [
            "bower_components/selectivizr/selectivizr.js",
            "bower_components/respond/dest/respond.min.js",
            "bower_components/REM-unit-polyfill/js/rem.js"
        ],
        dest: "assets/js/build/ie.js"
    },
    dist: {
        options: {
            separator: "\n\n"
        },
        src: [
            // Foundation Vendor
            "bower_components/foundation/js/vendor/fastclick.js",
            "bower_components/foundation/js/vendor/placeholder.js",
            // Foundation Core
            "bower_components/foundation/js/foundation/foundation.js",
            "bower_components/foundation/js/foundation/foundation.abide.js",
            "bower_components/foundation/js/foundation/foundation.accordion.js",
            "bower_components/foundation/js/foundation/foundation.alert.js",
            "bower_components/foundation/js/foundation/foundation.clearing.js",
            "bower_components/foundation/js/foundation/foundation.dropdown.js",
            "bower_components/foundation/js/foundation/foundation.interchange.js",
            "bower_components/foundation/js/foundation/foundation.joyride.js",
            "bower_components/foundation/js/foundation/foundation.magellan.js",
            "bower_components/foundation/js/foundation/foundation.offcanvas.js",
            "bower_components/foundation/js/foundation/foundation.orbit.js",
            "bower_components/foundation/js/foundation/foundation.reveal.js",
            "bower_components/foundation/js/foundation/foundation.tab.js",
            "bower_components/foundation/js/foundation/foundation.tooltip.js",
            "bower_components/foundation/js/foundation/foundation.topbar.js",
            // Custom Vendor

            // Project
            "assets/js/src/_init.js"

            ],
        dest: "assets/js/build/scripts.js"
    }
}

So as you can see, I'm specifying specific files (since I don't want to pull in an entire directory as you normally see it done), which seems simple enough. All tuts I've found for Gulp seem to follow that regex format:

gulp.task('scripts', function() {
  return gulp.src("assets/js/src/_init.js")
    .pipe(jshint('.jshintrc'))
    .pipe(jshint.reporter('default'))
    .pipe(concat('main.js'))
    .pipe(gulp.dest('assets/js/build'))
    .pipe(rename({ suffix: '.min' }))
    .pipe(uglify())
    .pipe(livereload(server))
    .pipe(gulp.dest('assets/js/build'))
    .pipe(notify({ message: 'Scripts task complete' }));
});

But putting in a comma-separated list into that src portion doesn't work -- how do we pass an array of files to that method?

It looks like I can separate my IE specific scripts using multiple streams in one, like so:

gulp.task('test', function(cb) {
    return es.concat(
        gulp.src('bootstrap/js/*.js')
            .pipe(gulp.dest('public/bootstrap')),
        gulp.src('jquery.cookie/jquery.cookie.js')
            .pipe(gulp.dest('public/jquery'))
    );
});

But a quick comment on if that is correct would be great too. Thanks!

Answer 1

From the documentation:

globs

Type: String or Array

Glob or globs to read.

In other words, pass in an array of strings, like:

gulp.src(['file1.js', 'file2.js']).pipe(...)
//       ^                      ^
//       '-------- Array -------'

Please note that this is the exact same format as Grunt. It's an array of globs, not a comma-separated list.
