{{rel}} NPM version

Handlebars helper for generating a relative link from the current page to the specified page.

Installation

Use npm to install the package: npm i handlebars-helper-rel.

Register the helper

The easiest way to register the helper with Assemble is to add the module to devDependencies and keywords in your project's package.json:

{
  "devDependencies": {
    "handlebars-helper-rel": "*"
  },
  "keywords": [
    "handlebars-helper-rel"
  ]
}

Alternatively, to register the helper explicitly in the Gruntfile:

grunt.initConfig({
  assemble: {
    options: {
      // the 'handlebars-helper-rel' npm module must also be listed in
      // devDependencies for assemble to automatically resolve the helper
      helpers: ['handlebars-helper-rel', 'foo/*.js']
    },
    files: {
      'dist/': ['src/templates/*.hbs']
    }
  }
});

Usage

With the helper registered, you may now begin using it in your templates:

<nav class="collapse navbar-collapse bs-navbar-collapse" role="navigation">
  <ul class="nav navbar-nav">
    <li> <a href="{{rel "foo/bar/one.html"}}">Masthead</a> </li>
    <li> <a href="{{rel "foo/bar/two.html"}}">Markdown</a> </li>
    <li> <a href="{{rel "foo/bar/three.html"}}">Readme</a> </li>
  </ul>
  <ul class="nav navbar-nav navbar-right">
    <li> <a href="{{rel "foo/bar/baz/four.html"}}">Blog</a> </li>
    <li> <a href="{{rel "foo/bar/baz/five.html"}}">About</a> </li>
  </ul>
</nav>

site.root

If a site.root variable is defined in the context, then you can omit that part from the paths.

For example, let's say you are using a _config.yml file:

grunt.initConfig({
  site: grunt.file.readYAML('_config.yml'),

  // Build HTML from templates and data
  assemble: {
    options: {
      // Metadata
      site: '<%= site %>',
      ...
    },
    example: {
      files: {'<%= site.dest %>/': ['<%= site.templates %>/*.hbs']}
    }
  }
});

And it contains a root variable:

root: foo/bar

Then you can omit foo/bar from the paths defined in your templates:

<nav class="collapse navbar-collapse bs-navbar-collapse" role="navigation">
  <ul class="nav navbar-nav">
    <li> <a href="{{rel "one.html"}}">Masthead</a> </li>
    <li> <a href="{{rel "two.html"}}">Markdown</a> </li>
    <li> <a href="{{rel "three.html"}}">Readme</a> </li>
  </ul>
  <ul class="nav navbar-nav navbar-right">
    <li> <a href="{{rel "baz/four.html"}}">Blog</a> </li>
    <li> <a href="{{rel "baz/five.html"}}">About</a> </li>
  </ul>
</nav>
