A minimal plugin to ngAnnotate for detecting Angular namespace collisions.

i.e. if you have the following in one area of your code:

angular.module('encore.cloud')
    .controller('MyFirstCtrl')

and this is another area:

angular.module('encore.ticketing')
    .factory('MyFirstCtrl')

an error will be raised.

To use this module with ngAnnotate, import it with require and pass to ngAnnotate with the plugin option, i.e.

const ngAnnotate = require("ng-annotate");
const nameCollision = require('../src/nameCollisionPlugin.js');

ngAnnotate(String(fs.readFileSync(filename)), {
    plugin: nameCollision
});

This will also work fine as a gulp task. An example of this is:

gulp.task('compile:detectCollision', function () {
    var scriptSourcePaths = [
        srcPath + '/src/**/*.js',
        srcPath + '/src/app.js',
        '!' + srcPath + '/src/**/*.spec.js',
    ];
    nameCollision.reset();
    return gulp.src(scriptSourcePaths)
        .pipe(plugins.plumber(function (err) {
            plugins.util.log(err.message);
            process.exit(1);
        }))
        .pipe(plugins.ngAnnotate({
            plugin: nameCollision
        }));
});//compile:detectCollision

Notice that when used in a gulp task, we call nameCollision.reset(). This is to account for something like gulp server, which usually keeps running and reruns all the tasks whenever your source code changes. In that situation, gulp does not reload the plugins, so the same instance of nameCollision is being used on every run. We want to make sure that the names discovered on the previous run are all cleared out, hence calling nameCollision.reset()
