mrowrpurr-pyscss 1.4.1

pyScss, a Scss compiler for Python (Fork with Python 3.13+ support)

This is a fork of pyScss by @mrowrpurr to add Python 3.13+ support.

Python 3.13+ enforces that global regex flags (like (?i), (?s), (?m)) must be at the start of a pattern. pyScss had several patterns with inline flags mid-pattern, which now raise re.PatternError. This fork converts them to scoped flag syntax (?i:...) or uses re.compile() flag arguments.

As of December 2025, pyScss has not received updates in 2+ years. This is published so I can use it as a dependency in my own Python 3.13+ projects.

pyScss, a Scss compiler for Python

pyScss is a compiler for the Sass language, a superset of CSS3 that adds programming capabilities and some other syntactic sugar.

Quickstart

You need Python 2.6+ or 3.3+. PyPy is also supported.

Installation:

pip install pyScss

Usage:

python -mscss < style.scss

Python API:

from scss import Compiler
Compiler().compile_string("a { color: red + green; }")

Features

95% of Sass 3.2 is supported. If it's not supported, it's a bug! Please file a ticket.

Most of Compass 0.11 is also built in.
