uv-pre-commit

A pre-commit hook for uv.

Distributed as a standalone repository to enable installing uv via prebuilt wheels from PyPI.

Using uv with pre-commit

To ensure the lockfile is up-to-date:

- repo: https://github.com/astral-sh/uv-pre-commit
  # uv version.
  rev: 0.9.5
  hooks:
    # Update the uv lockfile
    - id: uv-lock

To autoexport uv.lock to requirements.txt:

- repo: https://github.com/astral-sh/uv-pre-commit
  # uv version.
  rev: 0.9.5
  hooks:
    - id: uv-export

By default, this hook uses the "quiet" output.

To export to an alternative file, modify the args:

- repo: https://github.com/astral-sh/uv-pre-commit
  # uv version.
  rev: 0.9.5
  hooks:
    - id: uv-export
      args: ["--frozen", "--output-file=requirements-custom.txt", "--quiet"]

To compile your requirements via pre-commit, add the following to your .pre-commit-config.yaml:

- repo: https://github.com/astral-sh/uv-pre-commit
  # uv version.
  rev: 0.9.5
  hooks:
    # Run the pip compile
    - id: pip-compile
      args: [requirements.in, -o, requirements.txt]

To compile alternative files, modify the args and files:

- repo: https://github.com/astral-sh/uv-pre-commit
  # uv version.
  rev: 0.9.5
  hooks:
    # Run the pip compile
    - id: pip-compile
      args: [requirements-dev.in, -o, requirements-dev.txt]
      files: ^requirements-dev\.(in|txt)$

To run the hook over multiple files at the same time:

- repo: https://github.com/astral-sh/uv-pre-commit
  # uv version.
  rev: 0.9.5
  hooks:
    # Run the pip compile
    - id: pip-compile
      name: pip-compile requirements.in
      args: [requirements.in, -o, requirements.txt]
    - id: pip-compile
      name: pip-compile requirements-dev.in
      args: [requirements-dev.in, -o, requirements-dev.txt]
      files: ^requirements-dev\.(in|txt)$

To run a hook on a project within a subdirectory (i.e., in a monorepo):

- repo: https://github.com/astral-sh/uv-pre-commit
  # uv version.
  rev: 0.9.5
  hooks:
    # Update the uv lockfile
    - id: uv-lock
      # Change <path/to/project> to your relative path
      files: <path/to/project>/pyproject.toml
      args: [--project, <path/to/project>]

To synchronize your dependencies upon branch checkout, pull or rebase:

default_install_hook_types:
  - pre-commit
  - post-checkout
  - post-merge
  - post-rewrite
repos:
  - repo: https://github.com/astral-sh/uv-pre-commit
    # uv version.
    rev: 0.9.5
    hooks:
      - id: uv-sync

In order to install this hook, you either need to specify default_install_hook_types (as above) and run pre-commit install, or you have to install it via pre-commit install --install-hooks -t post-checkout -t post-merge -t post-rewrite.

To synchronize all dependencies in a workspace:

- repo: https://github.com/astral-sh/uv-pre-commit
  # uv version.
  rev: 0.9.5
  hooks:
    - id: uv-sync
      args: ["--locked", "--all-packages"]

If you use keyring to authenticate to a private index, include it as an additional sync dependency:

- repo: https://github.com/astral-sh/uv-pre-commit
  # uv version.
  rev: 0.9.5
  hooks:
    - id: uv-sync
      additional_dependencies: [keyring]
