action-ros-lint

This action runs ROS 2 linters on a ROS 2 package. This command does not compile any code intentionally to make it as fast as possible (<2 min). The objective is to give contributors feedback about their change quickly. It may also be used to avoid wasting CI resources (no need to compile, and run the tests if it does not pass the linters).

For linting requiring to compile code, or to compile and run tests, ros-tooling/action-ros-ci can be used instead.

Usage

See action.yml

Basic

container:
  image: ubuntu:noble
steps:
- uses: actions/checkout@v4
- uses: ros-tooling/setup-ros@master
- uses: ros-tooling/action-ros-lint@master
  with:
    linter: copyright
    package-name: your_package_name

Run generic and Python linters

jobs:
  ament_lint:
    runs-on: ubuntu-latest
    container:
      image: ubuntu:noble
    strategy:
      fail-fast: false
      matrix:
          linter: [copyright, flake8, mypy, pep257, pep8, xmllint]
    steps:
    - uses: actions/checkout@v4
    - uses: ros-tooling/setup-ros@master
    - uses: ros-tooling/action-ros-lint@master
      with:
        linter: ${{ matrix.linter }}
        package-name: your_package_name

Run generic and Python linters using a custom Docker image (experimental)

Using a custom Docker image removes the need to run setup-ros, which makes the runs less flaky, and faster. This setup is new, and experimental.

The docker image is provided by ros-tooling/setup-ros-docker.

jobs:
  ament_lint:
    runs-on: ubuntu-latest
    container:
      image: ghcr.io/ros-tooling/setup-ros-docker/setup-ros-docker-ubuntu-noble-ros-jazzy-ros-base
    strategy:
      fail-fast: false
      matrix:
          linter: [copyright, flake8, mypy, pep257, pep8, xmllint]
    steps:
    - uses: actions/checkout@v4
    - uses: ros-tooling/action-ros-lint@master
      with:
        linter: ${{ matrix.linter }}
        package-name: your_package_name
