A corpus-statutes YAML formatter with smart wrapping rules

YAML Lex Formatter

yaml-lex is a Python tool for reformatting YAML files with specific wrapping rules.

It is designed to make YAML files more readable and maintainable, particularly for content-heavy nodes like content, caption, and title.

Features

✅ Wraps long strings at a configurable line width ✅ Preserves blank lines and paragraph breaks ✅ Converts long text into block scalars (|-) for YAML readability ✅ Special rules for common keys: - content → always block scalar unless it contains a Markdown table - caption / title → flattened into single line, then wrapped if too long - Other long strings → wrapped into block scalars ✅ Detects and preserves Markdown tables (avoids breaking table formatting) ✅ Works on a single file or recursively on a folder of YAML files ✅ In-place editing or output to a new file

Notes

• Rich logging using rich.
• Fully compatible with doctest-style examples for testing.
• Supports CI/CD workflows with testing, linting, pre-commit hooks, and docs building.
