# Generator Templates:
What started as a generator to simply create some pre-defined files and stub them has evolved to included user defined boiler plates. Yeoman uses [EJS.co](http://ejs.co/) as it's templating engine so we've just built off of that.

Using the object returned from `mappings.js` we get some basic information. From there we loop over the array of files return which each item is an array of `[source, destination]` and copy the files in place. `Destination` is optional and if not provided we'll copy the structure it had coming in.


```js
// Here we output the marker tags with `%%`
const before = {
  args: [
  <%%% args.forEach((args) => { %>
    '<%%%= args -%>',
  <%%% }); -%>
  ],
  config: {
    domain: '<%%%= config.domain %>',
    root: '<%%%= config.root %>',
    templates: '<%%%= config.templates %>',
  },
  current: '<%%%= current %>',
  date: '<%%%= date %>',
  name: '<%%%= name %>',
  slug: '<%%%= slug %>',
  tag: '<%%%- tag %>',
  type: '<%%%= type %>',
}

// And this is the generated output
const after = {
  args: [
<%% args.forEach((args) => { -%>
    '<%%= args -%>',
<%% }); -%>
  ],
  config: {
    domain: '<%%= current %>',
    root: '<%%= current %>',
    templates: '<%%= current %>'
  },
  current: '<%%= current %>',
  date: '<%%= date %>',
  name: '<%%= name %>',
  slug: '<%%= slug %>',
  tag: '<%%- tag %>',
  type: '<%%= type %>'
}
```
