Font Awesome + Less + Rails 3.2+ Asset Pipeline

With LESS and fonts from Font Awesome, less-rails-fontawesome is a gem to integrate Font Awesome to your Rails 3.2+ application.

Updates

June 6 2012: Now using Font Awesome 2.0!

Installation

Add the gem to your assets group in the Gemfile:

    gem 'less-rails-fontawesome', :group => :assets

Then in your app/assets/stylesheets/application.css.less:

    @import 'fontawesome';

You can also use it with the less-rails-bootstrap gem. Just import fontawesome right after twitter/bootstrap:

    @import 'twitter/bootstrap';
    @import 'fontawesome';

(simple demo)

Helper methods

To place Font Awesome icon add i element and set its class attribute to a icon name, for example:

    <i class="icon-trash"></i>

To ease placing icons in Rails link_to helper use the ilink_to helper method.

For example, to place the icon-upload-alt icon next to Edit write something like:

    <%= ilink_to "upload-alt", "Edit", edit_post_path(post), class: 'btn btn-mini' %>

or to place icon-trash next to text Destroy button write:

    <%= ilink_to "trash", "Destroy", post, confirm: 'Are you sure?', method: :delete, class: 'btn btn-mini btn-danger'%>

(precede the link text with the icon name stripped off icon- prefix)
