Evil Front

Helpers, shortcuts and my common frontend workflows from Evil Martians.

The project is separated into 3 gems:

• Evil Front only contains helpers and doesn’t change the application environment.
• Evil Front All loads the workflow gems: Autoprefixer, Csso, Slim, JqueryCdn, Evil Blocks, Uglifier.
• Evil Front Rails loads the workflow gems and changes
  Rails settings to create my common frontend workflow with a single line of code.

You can safely use Evil Front Core, but the other two gems have side effects, so I recommend to only use them for new projects.

Some of the view helpers from Evil Front Core may require Rails, but most of them work with any Ruby application.

Helpers

The Evil Front Core gem contains assets and view helpers:

View Helpers

Typography

• russian_typograph to add typographical symbols (like Russian quotes, em-dash), non-breaking spaces.
• english_typograph to add typographical symbols (like quotes, ellipsis), non-breaking spaces.
• typograph_by_locale uses russian_typograph or english_typograph depend on current locale.
• auto_flying_quotes add tags to quotes to move it from text left horizontal line.
• ruble to insert the Russian currency character.
• capitalize_first to capitalize only first letter.

Head Tags

Workflow

The Evil Front All gem loads my must-have tools:

• Sass to write pretty styles.
• Slim to write pretty views.
• CoffeeScript to write pretty scripts.
• Uglifier to compress JS.
• CSSO to compress CSS.
• Sprockets to work with assets in best way.
• jQueryCDN to load latest jQuery in best way.
• Autoprefixer to add CSS3 prefixes.
• Rails Sass Images to inline images and get their sizes from Sass.
• Evil Blocks to manage your scripts.

Rails Settings

The Evil Front Rails gem changes default Rails settings:

• Autoprecompile adds all files in root of app/assets/stylesheets and app/assets/javascripts to precompile. You should only store loadable files in subdirs.
• Disable assets generation on controller and action generation.
