metalsmith-rootpath

Easily find the relative path to the root directory in your Metalsmith templates.

Makes relative-to-root links a breeze!

Note: metalsmith-rootpath must run after any plugins that move files around, or create new files in your
metalsmith build chain (like metalsmith-permalinks, for example).
This is because metalsmith-rootpath needs to know what your final output directory will look like before it can assign
a correct rootPath value.

Install

$ npm install --save metalsmith-rootpath

Usage

 var rootPath = require('metalsmith-rootpath');

Metalsmith(__dirname)
  .use(rootPath())
  .build(function(err) {
    if (err) throw err;
  });
  

:sunglasses: Now all the files and templates in your Metalsmith build have a rootPath variable assigned to them!
I am using the handlebars template in the examples below, but you can use your template language of choice, or access
the rootPath value from the file's metadata in anyway you like.

Examples

Let's assume you have a directory structure like this:

.
├── index.html
│
├─┬ dir1/
│ └── index.html
│  
├─┬ dir2/ 
│ └─┬ foo/
│   └── index.html
│
└─┬ dir3/ 
  └─┬ foo/
    └─┬ bar/
      └─┬ baz/
        └── index.html

The rootPath values in each index.html file would be:

Relative Links

Use the rootPath variable anywhere you want to grab static files relative to your directory. rootPath will
find the root folder no matter how many levels deep your templates are.

For example, if the following line of markup were placed in dir3/foo/bar/baz/index.html:

 <link src="{{rootPath}}css/main.css" type="text/css" />

It would result in the following output:

 <link src="../../../../css/main.css" type="text/css" />

Relative Navigation

This rootPath variable is useful when building a relative navigation structure, for example, in your Handlebars
template partials/navigation.hbs

 <ul>
    <li><a href="{{rootPath}}about/">About Us</a></li>
    <li><a href="{{rootPath}}awesome-page/">Awesome Page</a></li>
    <li><a href="{{rootPath}}contact/">Contact Us</a></li>
</ul>
