Lint Brush

A linter which focuses on the low-level things that are common across many repositories. Leaves the language-specific linting to more appropriate tools.

I'm moving from pre-commit to lefthook, and don't want to have to deal with a Python installation and particular ways of needing to set up a virtualenv. So I'm rewriting the most relevant rules in Go so they can be compiled into a standalone binary.

Caution

This is a brand-new project and most of this isn't working yet. Check back later.

Plan

Usage

1. Pass files as arguments.

   lint-brush [--flags] $(git ls-files -m)

2. Pipe a list of files.

   git ls-files -m | lint-brush [--flags]

3. Pipe a list of files using NUL as the separator.

   git ls-files -m -z | lint-brush -0 [--flags]

   Or all files in a directory, except for the Git directory (using fd)…

   fd --unrestricted --exclude=.git --prune --type=file . | lint-brush [--flags]

Checks/fixers

Will be porting a number of checks from Python → Go for this effort.

• check: binary files should be stored in Git LFS
• check: executable text files should have shebangs
• check: find broken synlinks
• check: GitHub code links should be permalinks
• check: JSON/JSONC/JSON5 is well-formed
• check: large files added
• check: merge conflict markers
• check: problems with case-sensitive file systems
• check: TOML is well-formed
• check: XML is well-formed
• check: YAML is well-formed
• fix: destroyed symlinks
• fix: files should end with a final linebreak
• fix: mixed line endings
• fix: remove trailing whitespace on lines
• fix: remove UTF-8 BOM
