Fawkss [fɔːks] is a simple CSS preprocessor built as a single AWK (nawk/gawk/mawk) script. Syntactically, it borrows as much as possible from the SASS language, for convenience and familiarity.

This is more of a fun project than a production-ready piece of software, though it may find some use for people needing simple additions to CSS without pulling in the massive ecosystem that comes with Less.js/SASS etc.

Currently, the following features are implemented:

• C99/C++-style comments (i.e. // This is a comment)
• Variables

A full test-suite is provided (depending only on make and awk), which should serve as a good example of the existing feature-set.

It is intended that the script never balloons to more than ~1000 lines of code. I'm trying to tackle the most important features yet and see how well they fit within the AWK mindset.

That being said, I do not plan to implement any context-sensitive functionality (such as nesting etc.), which may be nigh-impossible in AWK anyways. Consider it a feature.

A Makefile is provided for running tests and producing documentation for Fawkss. Run make help in the project root for more information.

Nope. I wouldn't suggest you actually use this for anything, though.
