www/ruby-crass 1.0.7 NetBSD

Crass is a Ruby CSS parser that's fully compliant with the CSS Syntax Level 3 specification.

Features

* Pure Ruby, with no runtime dependencies other than Ruby 1.9.x or higher.

* Tokenizes and parses CSS according to the rules defined in the 14 November 2014 editor's draft of the [CSS Syntax Level 3][css] specification.

* Extremely tolerant of broken or invalid CSS. If a browser can handle it, Crass should be able to handle it too.

* Optionally includes comments in the token stream.

* Optionally preserves certain CSS hacks, such as the IE "*" hack, which would otherwise be discarded according to CSS3 tokenizing rules.

* Capable of serializing the parse tree back to CSS while maintaining all original whitespace, comments, and indentation.
