Transform Require.js modules to use simplified CommonJS wrapper

1.md

Transform your code from:

define(['backbone', './model', './mySync'], function(Backbone, Model, mySync) {

    var Collection = Backbone.Collection.extend({

        model: Model,
        sync: mySync

    });

    return Collection;

});

to using the simplified CommonJS wrapper:

define(function(require) {

    var Backbone = require('backbone');
    var Model = require('./model');
    var mySync = require('./mySync');

    var Collection = Backbone.Collection.extend({

        model: Model,
        sync: mySync

    });

    return Collection;

});

2.js

var _ = require('underscore');
var fs = require('fs');
var glob = require('glob');

var jsFiles = glob.sync('./src/main/webapp/javascript/**/*.js');

_.each(jsFiles, function(file) {
    var content = fs.readFileSync(file, 'utf8');

    var match = content.match(/define\(\s*\[([^\]]+)\s*\],\s*function\s*\(([^\)]+)\)\s*{/);

    if (!match) return;

    echo(file);

    var deps = match[1].split(',');
    var funcs = match[2].split(',');

    var indent = '    ';
    var cjsRequire = "define(function(require) {\n\n" + indent;

    var requires = _.map(deps, function(dep, i) {
        var func = funcs[i];
        var depRequire = 'require(' + dep.trim() + ');';

        if (func) {
            return 'var ' + func.trim() + ' = ' + depRequire;
        } else {
            return depRequire;
        }
    });

    var newRequire = cjsRequire + requires.join("\n" + indent);

    fs.writeFileSync(file, content.replace(match[0], newRequire), 'utf8');
});
