in order to use it on your own (Grunt) project build file.
If you don't know what Grunt is then to explain it on one leg -
"Grunt is a pluggable (JavaScript) task runner", which can be used to build JavaScript projects.
Such typical build of a Javascript project may contain a Linting task, minification task, and so on...
So, you can read more about Grunt if you want to get a better understanding.
And now, to the recipe!
Ingredients:
1 NPM installed on your machine
1 GIT installed on your machine
1 Skill writing a tiny bit of Javascript
A zest of patience
Instructions:
1. First thing would be to install a Grunt plugin that is used for templates scaffolding.
In order to do that, you need to run the following in your shell:
$ npm install -g grunt-initGrunt Plugin. (https://github.com/gruntjs/grunt-init-gruntplugin)
So, run the following in your shell:
$ git clone https://github.com/gruntjs/grunt-init-gruntplugin.git ~/.grunt-init/gruntplugin$ mkdir my-custom-plugin
$ cd my-custom-plugin
Then run the following in your shell:$ grunt-init gruntpluginYou should be seeing something like this:
Please answer the following:
[?] Project name (grunt-my-custom-plugin)
[?] Description (The best Grunt plugin ever.) the best custom plugin ever!
[?] Version (0.1.0)
[?] Project git repository (ssh://<Your GIT remote Repository URL>)
[?] Project homepage (none)
[?] Project issues tracker (none)
[?] Licenses (MIT)
[?] Author name (nirgit) Nir M
[?] Author email (getnirm@gmail.com)
[?] Author url (none) tech-drum.blogspot.com
[?] What versions of grunt does it require? (~0.4.2)
[?] What versions of node does it run on? (>= 0.8.0)
[?] Do you need to make any changes to the above before continuing? (y/N) N

Initialized from template "gruntplugin".
You should now install project dependencies with npm install. After that, you
may execute project tasks with grunt. For more information about installing
and configuring Grunt, please see the Getting Started guide:
http://gruntjs.com/getting-started
Done, without errors.
5. Now you should have your directory containing a Grunt Plugin template.
Open the file you have inside the "tasks" directory in order to edit it.
6. The file should look as follows:
7. Just in order to get started, lets strip the file and change it to contain the following:
/*
* grunt-my-custom-plugin
*
*
* Copyright (c) 2014 Nir M
* Licensed under the MIT license.
*/
'use strict';
module.exports = function(grunt) {
grunt.file.defaultEncoding = 'utf8';
// Please see the Grunt documentation for more information regarding task
// creation: http://gruntjs.com/creating-tasks
grunt.registerTask('my_custom_plugin', function() {
grunt.log.writeln('Hello my great Grunt Plugin!') ;
});
};
you'll execute at the end.
Lets change the Gruntfile.js in the root directory of the Plugin so tests won't execute when
we will run "grunt" on the plugin's source. Otherwise the build would fail.
So now the Gruntfile.js last line should look like:
grunt.registerTask('default', ['jshint']);
8. Go back to the root directory of your Grunt Plugin and run the following:
$ npm install
9. Almost done.$ gruntRunning "jshint:all" (jshint) task >> 3 files lint free. Done, without errors.
Now go to your own project where you want to use your plugin and add the following line to the
Gruntfile.js of your project:
grunt.loadNpmTasks('grunt-my-custom-plugin');
This will load your Grunt plugin task to your Grunt's project.10. Next step would be to install the plugin locally in the node modules of your Proect.
You should now run in the root directory of your Project (where you want to use your plugin) the following:
$ npm install /<PATH_TO_YOUR_PLUGIN>/my-custom-plugin
11. You should now be able to execute:$ grunt my_custom_plugin
And see:Running "my_custom_plugin" task Hello my great Grunt Plugin! Done, without errors.
That's all folks.
Hope this was helpful to get you started with Grunt Plugins.
Don't forget to publish it (npm publish) afterwards to the rest of the Node community if you think it may be helpful to others as well.

Good luck!
