python-waterloo-lexer 0.5.10

A pygments lexer derived from the Python lexer, for Waterloo docstrings

Python-Waterloo Lexer

python-waterloo-lexer is a Pygments lexer for Python files that contain Waterloo docstrings.

The Waterloo Docstrings project defines a structured docstring format with explicit section semantics, normativity rules, and multiple render targets. The project is designed so that the same source docstring can be consumed by humans, LLM-assisted tooling, and renderers without losing structural meaning. This lexer provides syntax highlighting that preserves those conventions in editors, terminals, and preview tools.

It can be used with pygmentize and other tools that load Pygments lexers via entry points.

What it provides

• a python-waterloo Pygments lexer alias
• syntax highlighting for Python files with Waterloo docstrings
• installation via PyPI, local checkout, or Git URL

Installation

pip install python-waterloo-lexer

Quick test

After installation, the lexer is available under the alias python-waterloo.

pygmentize -l python-waterloo -f terminal16m <file.py>

You can also check whether Pygments lists the lexer:

pygmentize -L lexers | grep -i waterloo || true

Terminal viewer

For a quick terminal preview, a less alias can be handy:

alias lessh='LESSOPEN="| pygmentize -O style=monokai %s" less -M -R'

Then open files with:

lessh <file.py>

Source repository

Development happens in the Waterloo repository:
