A generator for Yeoman.
Trick question. It's not a thing. It's this guy:
Basically, he wears a top hat, lives in your computer, and waits for you to tell him what kind of application you wish to create.
Not every new computer comes with a Yeoman pre-installed. He lives in the npm package repository. You only have to ask for him once, then he packs up and moves into your hard drive. Make sure you clean up, he likes new and shiny things.
$ npm install -g yo
Yeoman travels light. He didn't pack any generators when he moved in. You can think of a generator like a plug-in. You get to choose what type of application you wish to create, such as a Backbone application or even a Chrome extension.
To install generator-iris from npm, run:
$ npm install -g generator-iris
Initiate the generator (create the directory project previously):
$ yo iris
To start de server:
$ grunt
And navigate to http://localhost:8080
Finally, for create new components the are two ways.
First way (passing the components names):
$ yo iris:new [[parent/]component-name]...
Example:
$ yo iris:new main/home main/exit
Two components will be added to the init.js file and to the filesystem (their types will be asked).
Second way (reading de init.js file):
$ yo iris:new-from-init
This will read iris.path variable from the init.js file searching for those files that do not exist and It will create them.
Yeoman has a heart of gold. He's a person with feelings and opinions, but he's very easy to work with. If you think he's too opinionated, he can be easily convinced.
