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 - git-format-staged is commonly compared with lint-staged, pre-commit, pretty-quick, precise-commits, Husky, and formatter tools such as Prettier. ### Sources - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** git-format-staged - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Related links - [Source-control packages](https://pkg.so/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://pkg.so/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://pkg.so/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [gh](https://pkg.so/brew/gh/) - Shares pkgdb curated category or tags: cli, developer-tools, git. - [libgit2](https://pkg.so/brew/libgit2/) - Shares pkgdb curated category or tags: cli, developer-tools, git. - [glab](https://pkg.so/brew/glab/) - Shares pkgdb curated category or tags: cli, developer-tools, git. - [git-lfs](https://pkg.so/brew/git-lfs/) - Shares pkgdb curated category or tags: cli, developer-tools, git. - [lazygit](https://pkg.so/brew/lazygit/) - Shares pkgdb curated category or tags: cli, developer-tools, git. - [bat](https://pkg.so/brew/bat/) - Shares pkgdb curated category or tags: cli, developer-tools, git. - [git-filter-repo](https://pkg.so/brew/git-filter-repo/) - Shares pkgdb curated category or tags: cli, developer-tools, git. - [git-delta](https://pkg.so/brew/git-delta/) - Shares pkgdb curated category or tags: cli, developer-tools, git. - [git-format-staged](https://pkg.so/npm/git-format-staged/) - Same normalized package name appears in another local ecosystem.
