markfmt

Every Markdown file in one canonical style. Zero config.

brew install strangemattersystems/tap/markfmt

docker run --rm -v "$PWD:/work" -w /work ghcr.io/strangemattersystems/markfmt README.md

go install github.com/strangemattersystems/markfmt/cmd/markfmt@latest

Why markfmt

• Fast. It will never be the bottleneck.
• Zero config. Nothing to set up, nothing to argue about.
• Idempotent. Format twice, get the same file.
• Safe. It never changes what your document means.
• One binary. No Node, no Python, no plugins.

Use it

markfmt README.md docs/*.md              # format in place
markfmt -check $(git ls-files '*.md')    # fail CI on unformatted files
