# CSS Compare
Processes, evaluates and compares 2 CSS files based on their AST. The repository has been created in order to be able to test the [less2sass](https://github.com/vecerek/less2sass) project. The program returns `true` or `false` to the `$stdout`, so far.
Uses the Sass parser to get the CSS files' AST.
Supported CSS features:
- all types of selectors (they are normalized - duplicity removal and logical/alphabetical ordering)
- @media, partially
- @import (lazy loading of imported css files, that can be found, otherwise ignored)
- @font-face
- @namespace
- @charset
- @keyframes
- @page
- @supports, partially
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'css_compare'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install css_compare
## Usage
Command line usage:
$ css_compare
Programmatic usage:
```ruby
opts = {
:operands => ["path/to/file1.css", "path/to/file2.css"]
}
result = CssCompare::Engine.new(opts)
.parse!
.equal?
```
## TODO
- Evaluate shorthand properties, so the values of base properties get overridden.
- Evaluate @media rule's and @supports rule's conditions.
- Output the difference, optionally.
