entypo-rails

An asset pipeline plugin for Rails to easily add the Entypo icon font faces and an initial set of icon classes.

Entypo

The Entypo pictograms by Daniel Bruce http://www.entypo.com/ are provided in vendor. These pictograms are licensed under CC BY 3.0 and the font unter SIL Open Font License.

Installation

Add this line to your application's Gemfile:

gem 'entypo-rails'

And then execute:

$ bundle

Then start your server and open

http://localhost:3000/entypo/charmap

Usage

Either use the provided mappings, based on icons-... and the :before:

// application.css[.scss]
//= require entypo
@charset "UTF-8";

<!-- some_template.html... -->
This is cool <i class="icon-thumbs-up"></i>.
Fork it on <i class="icon-social-github"></i>.

or just include the entypo font face and do the mappings yourself, go to http://localhost:3000/entypo/charmap in your browser for a list of all unicode codepoints and CSS classes. This is only available in development mode. Alternatively check out entypo.css.scss, the social font is prefixed with .icon-social-.

// application.css[.scss]
//= require entypo-fonts
@charset "UTF-8";

// icons.css.scss (or wherever)
i.cool { font-family: 'entypo' }
i.cool:before { content: "\1F44D"; }

<!-- some_template.html... -->
This is cool <i class="cool"></i>.

Options

Change the icon prefix

Simply add an initializer like e.g. config/initializers/entypo.rb and add:

Entypo.css_prefix = "my-icon"

After setting a new prefix restart your server and ensure to clear the Rails asset caches in tmp/cache/asset, otherwise the new prefix might not be picked up correctly.

Note: that the value is not checked, thus ensure to use onlu valid CSS class names.

Enable the /entypo/charmap in a non-development environment

By default entypo-rails only enables the /entypo/charmap route in the development environment. To enable it in another environment open the environment specific configuration file from config/environments/<env>.rb and append:

# at the end of the file...
Entypo.charmap = true

Customize the charmap path (or add authorization etc.)

To use a custom URL for to display the charmap, first disable the automatic route generation by adding an initializer e.g. config/initializers/entypo.rb with:

Entypo.charmap = false

Then add a new route to your application's config/routes.rb file:

Your::Application.routes.draw do
  # other routes...
  get '/custom/path/to/charmap', to: 'entypo/charmap#index'
end

Troubleshooting

The prefix icon clashes with the prefix defined by bootstrap and thus I'm not able to use entypo icons.

The prefix can be changed by setting Entypo.css_prefix = "e-icon" in an initializer. Ensure that after changing the prefix the caches in tmp/cache/assets should be cleared, otherwise it can happen that the prefix is not picked up during development.

In production, the fonts are digested to entypo- 4a74efb3ed26fe0c57556bcc0b7e871f... Meanhwile it's just entypo.eot in the CSS file, without the digest. Therefore the font cannot be loaded!

When compiling assets ensure to set the correct RAILS_ENV, otherwise assets or not digested in the CSS files. See this discussion for more, or simply ensure to run:

RAILS_ENV=production rake assets:precompile
