prefdep: apply dependencies to all RequireJS modules sharing a common prefix, for example, make 'angular-cookies' and 'angular-translate' depend on 'angular' with `prefdep('angular-', 'angular')`

prefdep.js

/* global define, require */

define(['lodash'], function(_) {
    'use strict';

    function prefdep(prefix, parent_module) {

        // grab a convenient reference to the requirejs config
        var rjsconf = require.s.contexts._.config;

        // create a shim entry, giving 'name' module a dependency on 'parent'
        function create_shim(parent) {
            return function (path, name) {
                var newshim = {};
                newshim[name] = {
                    deps: [parent]
                };
                return newshim;
            };
        }

        // merge the new shim object from create_shim into the global requirejs
        // config
        function inject_shim(conf) {
            return function (newshim) {
                _.merge(conf.shim, newshim);
            };
        }

        // if a module name begins with prefix, but isn't equal to prefix, call
        // it a match.  for example, if prefix is "angular", then
        // "angular-ui-router" matches, but "angular" itself doesn't, since we
        // want angular-ui-router to depend on angular, but we definitely don't
        // want angular to depend on itself.
        function dependson(parent) {
            return function (path, name, object) {
                return name !== parent && name.indexOf(parent) === 0;
            };
        }

        // find the children of prefix
        var babies = _.pick(rjsconf.paths, dependson(prefix));

        // give each child a dependency on their parent
        _.each(babies, _.compose(inject_shim(rjsconf), create_shim(parent_module)));
    }

    return prefdep;
});

Usage:

require(['prefdep'], function(prefdep) {
    prefdep('angular-', 'angular');
});
