git-codeowners

A git subcommand to query and validate CODEOWNERS.

List owners of files based on the CODEOWNERS file of the current repository.

> git codeowners src/main.rs
src/main.rs                              @weyland

> git codeowners `git ls-files`
.gitignore                               (unowned)
Cargo.lock                               @weyland
Cargo.toml                               @weyland
LICENSE                                  (unowned)
README.md                                @weyland
src/main.rs                              @weyland

# Oops, did the last commit add unowned files?
> git diff --name-only --diff-filter=A | git codeowners
.gitignore                               @bob
LICENSE                                  (unowned)

# I need stats about my repo
> echo `git ls-files | git codeowners | grep "(unowned)"| wc -l` out of `git ls-files | git codeowners | wc -l` files in this repository do not have a corresponding CODEOWNERS entry
2 out of 6 files in this repository do not have a CODEOWNERS entry

Installation

• via pip: pip install git-codeowners

• via Cargo: cargo install git-owners

  Note: The Cargo crate installs an equivalent git-owners command in addition to git-codeowners, for backwards compatibility.

Usage

• Show owner of a file

  git codeowners some/path
  

• Show owners for a list of files

  git codeowners some/path some/other/path
  

Each path should be relative to the git repository root. This makes it easy to combine with other git commands:

• Show owners for every tracked file in the repository

  git ls-files | git codeowners
  

• Show owners for files modified in last five commits

  git diff --name-only HEAD~5 HEAD | git codeowners
  

• Congratulate the user if the current changeset does not add files without owner

  git diff --diff-filter=ACR --name-only | git codeowners && echo "Great job! No unowned files added!"
  

• Get an overview of your CODEOWNERS coverage

  echo `git ls-files | git codeowners | grep "(unowned)"| wc -l` out of `git ls-files | git codeowners | wc -l` files in this repository do not have a CODEOWNERS entry
  

Features

• Detects the right CODEOWNERS file of the current git repository (CODEOWNERS, docs/CODEOWNERS, or .github/CODEOWNERS)
• Works well as a pre-commit hook. Returns a non-zero exit code if unowned files are found
• Is composable & scripting friendly
• Is fast & written in Rust
