    <% if (deps && deps.length) { %>
    [
        <% var l = args.length; deps.forEach(function(dep, index) { %>
        '<%-dep%>'<% if (l - 1 !== index) {%>,<% } %>
        <% }); %>
    ],

Tip

You can also change the output by yourself

gulpfile.js

const path = require('path');
const gulp = require('gulp');
const gulpWithTemplate = require('gulp-with-template');

const templateFilePath = path.join(process.cwd(), 'template.js');

gulp.task('module1', function() {
    return gulp.src(['module1.js'])
        .pipe(gulpWithTemplate(templateFilePath, {
            modulename: 'module1',
            deps: ['module2'],
            args: ['m2']
        }, function(file, content /* String */, _ /* lodash */) {
            // you must return a string
            return _.unescape(content); // for example
        }))
        .pipe(gulp.dest('dist'))
});

gulp.task('module2', function() {
    return gulp.src(['module1.js'])
        .pipe(gulpWithTemplate(templateFilePath, {
            modulename: 'module2',
            deps: null,
            args: null
        }, function(file, content /* String */, _ /* lodash */) {
            // you must return a string
            return _.unescape(content); // for example
        }))
        .pipe(gulp.dest('dist'))
});


// dynamic
gulp.task('together', function() {
    return gulp.src(['module1.js', 'module2.js'])
        .pipe(gulpWithTemplate(function(file) {
            let options = null;

            if (file.path.indexOf('module1.js') !== -1) {
                options = {
                    modulename: 'module1',
                    deps: ['module2'],
                    args: ['m2']
                };
            } else {

                    args: null
                };
            }

            return {
                template: templateFilePath,
                // contentName: 'content' // - if you want to change standard content name
                options: options
            };
        }, function(file, content /* String */, _ /* lodash */) {
            // you must return a string
            return _.unescape(content); // for example
        }))
        .pipe(gulp.dest('dist'))
