No Longer Maintained

Please consider this project abandoned. There are many roadblocks that prevent upgrading this to the latest Semantic-UI and now there's Fomantic-UI. #53. I suggest you look at bundling Fomantic-UI in with webpacker instead. It is possible though not completely straightforward. This project is starting to get security tickets around dependencies (that I won't fix), so user beware.

less-rails-semantic_ui

This is a gem for Rails with Semantic UI assets inside. It provides the ability to customize component themes and variables on the fly in your application.

Features

• LESS based (meaning that it doesn't contains hacks usually used to convert LESS to SASS)
• Semantic UI configs integrated in your application (you can customize and change component styles on the fly)

Installation

Add this block to your application's Gemfile:

# Semantic UI assets

gem 'less-rails-semantic_ui'
gem 'autoprefixer-rails'
gem 'therubyracer'

Semantic UI is using autoprefixer (in our case autoprefixer-rails) to appending additional CSS vendor-prefixes for improve compatibility with different browsers. Without it some parts of Semantic UI (i.e. transitions or modal dialogs because they depends to transitions) won't works in some browsers. You can remove this gem if you don't use such functionality of Semantic UI.

P.S. I hope in the future this hack will be unnecessary.

And then execute:

$ bundle install

After that, install configuration files inside your application in the vendor/assets directory with:

$ rails generate semantic_ui:install

Require semantic_ui/semantic_ui.js in app/assets/application.js:

...
//= require semantic_ui/semantic_ui
...

Require semantic_ui/semantic_ui.css in app/assets/application.css:

...
*= require semantic_ui/semantic_ui
...

Upgrade to new version

Execute command below and merge your custom and new changes in config files:

$ rails generate semantic_ui:install

Customization

You can modify any Semantic UI configs and files placed to vendor/assets/javascripts/semantic_ui and vendor/assets/stylesheets/semantic_ui directories. For example:

• if you wish to remove unused components you can just remove corresponding lines from semantic_ui.js and semantic_ui.css files.
• if you wish to change components themes you can just configure them in theme.config.
• if you wish to change component variables or extend components you can just configure corresponding config/{collections,elements, globals,modules,views}/*.{overrides,variables} files.

Versioning

This gem will directly track the semantic versioning of the Semantic UI project. Major and minor versions will always match to theirs, though we may have tiny patch level releases specific to this gem.
