# Bootstrap for Sass

[![Build Status](https://secure.travis-ci.org/thomas-mcdonald/bootstrap-sass.png?branch=master)](http://travis-ci.org/thomas-mcdonald/bootstrap-sass) [![Code Climate](https://codeclimate.com/github/thomas-mcdonald/bootstrap-sass.png)](https://codeclimate.com/github/thomas-mcdonald/bootstrap-sass)

`bootstrap-sass` is an Sass-powered version of [Bootstrap](http://github.com/twbs/bootstrap), ready to drop right into your Sass powered applications.

## Installation

Please see the appropriate guide for your environment of choice:

### a. Rails

`bootstrap-sass` is easy to drop into Rails with the asset pipeline.

In your Gemfile you need to add the `bootstrap-sass` gem, and ensure that the `sass-rails` gem is present - it is added to new Rails applications by default.

```ruby
gem 'sass-rails', '>= 3.2' # sass-rails needs to be higher than 3.2
gem 'bootstrap-sass', '~> 2.3.2.1'
```

If you would like to use the beta Bootstrap 3 version of bootstrap-sass, use the master branch:

```ruby
# Experimental Bootstrap 3.0 beta -- use at your own risk.
gem 'sass-rails', '>= 3.2'
gem 'bootstrap-sass', github: 'thomas-mcdonald/bootstrap-sass'
```

`bundle install` and restart your server to make the files available through the pipeline.

## b. Compass (without Rails)

Install the gem
```console
gem install bootstrap-sass
```

If you have an existing Compass project:

```ruby
# config.rb:
require 'bootstrap-sass'
```

```console
compass install bootstrap
```

If you are creating a new Compass project, you can generate it with bootstrap-sass support:

```console
compass create my-new-project -r bootstrap-sass --using bootstrap
```

This will create a new Compass project with the following files in it:

[_variables.scss](/blob/master/templates/project/_variables.scss.erb) - all of bootstrap variables (override them here).
[styles].scss(/blob/master/templates/project/styles.scss) - main project SCSS file. import `variables` and `bootstrap`.

## Sass (without neither Compass nor Rails)

Raw Sass support is coming soon!

### Usage

#### CSS

Import Bootstrap in an SCSS file (for example, `application.css.scss`) to get all of Bootstrap's styles, mixins and variables! We recommend against using `//= require` directives, since none of your other stylesheets will be [able to access][antirequire] the Bootstrap mixins or variables.

```css
@import "bootstrap";
```

You can also include optional bootstrap theme:

```css
@import "bootstrap/theme";
```

#### Javascript

We have a helper that includes all Bootstrap javascripts. Put this in your Javascript manifest (usually in `application.js`) to

```js
// Loads all Bootstrap javascripts
//= require bootstrap
```

You can also load individual modules, provided you also require any dependencies. You can check dependencies in the [Bootstrap JS documentation][jsdocs].

```js
//= require bootstrap/scrollspy
//= require bootstrap/modal
//= require bootstrap/dropdown
```

## Development and Contributing

If you'd like to help with the development of bootstrap-sass itself, read this section.

### Upstream Converter

Keeping bootstrap-sass in sync with upstream changes from Bootstrap used to be an error prone and time consuming manual process. With Bootstrap 3 we have introduced a converter that automates this.

**Note: if you're just looking to *use* Bootstrap 3, see the [installation](#installation) section above.**

Upstream changes to the Bootstrap project can now be pulled in using the `convert` rake task.

Here's an example run that would pull down the `3.0.0-wip` branch from the main twbs/bootstrap repo (defaults to `master`):

    bundle exec rake convert[3.0.0-wip]

The latest converter script is located [here][converter] and does the following:

* Converts upstream bootstrap LESS files to its matching SCSS file.
* Copies all upstream JavaScript into `vendor/assets/javascripts/bootstrap`
* Generates a javascript manifest at `vendor/assets/javascripts/bootstrap.js`
* Copies all upstream font files into `vendor/assets/fonts/bootstrap`
* Sets `Bootstrap::BOOTSTRAP_SHA` in [version.rb][version] to the branch sha.

This converter fully converts original LESS to SCSS. Conversion is automatic but requires instructions for certain transformations (see converter output).
Please submit GitHub issues tagged with `conversion`.
