# action-ros-lint

[![GitHub Action Status](https://github.com/ros-tooling/action-ros-lint/workflows/Test%20action-ros-lint/badge.svg)](https://github.com/ros-tooling/action-ros-lint)
[![Dependabot Status](https://api.dependabot.com/badges/status?host=github&repo=ros-tooling/action-ros-lint)](https://dependabot.com)

This action runs [ROS 2](https://index.ros.org/doc/ros/) 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.

## Developing

For development and release workflows, see [DEVELOPING.md](DEVELOPING.md)

## Usage

See [action.yml](action.yml)

### Basic

```yaml
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

```yaml
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].

```yaml
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
```
