history

Project history and usage

git-format-staged is a Python Git helper that runs a formatter or linter against the staged version of files, preserving unstaged working-tree edits.

Project history

The repository began in March 2018. Its README explains the project as a response to pre-commit formatting hooks that run a formatter over working-tree files and then restage the result, a pattern that can accidentally commit unrelated unstaged edits or disrupt `git add -p` workflows.

Adoption history

git-format-staged sits in the ecosystem around Prettier, Husky, lint-staged, pre-commit, pretty-quick, and language-specific hook managers. It distinguishes itself by formatting blobs from the Git index and then attempting to patch the working tree afterward, rather than stashing user edits before formatting.

How it is used

Practitioners install it through Nix, npm, Homebrew, or by copying the script, then call it from pre-commit hooks with a formatter command that reads from stdin and writes to stdout. Typical use passes file patterns and a formatter placeholder, such as running Prettier with `--stdin-filepath` for staged JavaScript, TypeScript, or CSS files.

Why package nerds care

The package is notable because it solves a small but sharp Git-index problem without tying users to one language ecosystem. That makes it attractive for polyglot repositories and hook setups where the important boundary is Git's staged content rather than a particular formatter.

Timeline

  • 2018: The repository began with an initial commit.
  • 2018: The v1.0.0 tag established the installable Git helper.
  • Later releases: Packaging expanded across npm, Nix, and Homebrew usage paths.

Related projects
