Framework to create linters for Python, YAML, TOML, JSON

Hacker News

Hi, this is a Python framework I have created to make my life a little easier when creating custom linting rules. Key features: - Quick to use (~20 LOC to create a functioning linter/checker) - Works with different file formats (as in the description) - Supports multiple ignore/noqa directives (per-line ignores, range ignores, whole file, rules choice during runs) - Single check can span all elements of the file or even all files - Works directly with Python's AST - Tutorials and API reference to make users life easier All in all seems to be quite functional for my private (yet) linters, so I decided to make it into a FOSS project. Have fun, would love to hear your feedback and ideas regarding it!
