GitHub Actions action that uses Arduino Lint to check for problems with Arduino projects:

• Libraries
• Sketches
• Boards platforms
• Boards Manager package indexes

• Inputs
  • path
  • version
  • compliance
  • library-manager
  • project-type
  • recursive
  • report-file
  • verbose
  • token
• Usage
• Contributing

Path containing Arduino project(s).

Default: ./

The version of Arduino Lint to use. Can be an exact version (e.g., 1.0.0) or a version range (e.g., 1.x).

Default: 1.x

Configure how strict the tool is about which checks are considered errors vs warnings if they don't pass.

• strict - enforces best practices, above and beyond the minimum requirements for specification compliance. Use this setting to ensure the best experience for the users of the project.
• specification - enforces compliance with the official Arduino project specifications.
• permissive - will cause the checks to fail only when severe problems are found. Although a project that passes at the permissive setting will work with the current Arduino development software versions, it may not be fully specification-compliant, risking incompatibility or a poor experience for the users.

Default: specification

Configure the checks for libraries in the Arduino Library Manager index.

• submit - Also run additional checks required to pass before a library is accepted for inclusion in the index.
• update- Also run additional checks required to pass before new releases of a library already in the index are accepted.
• false - Don't run any Library Manager-specific checks.

Default: submit for libraries, false for other project types

Configures which types of projects to check, along with their subprojects.

• sketch
• library
• platform - boards platform
• package-index - Boards Manager package index
• all - Run checks on any type of project that is detected

Default: all

Set to true to search path recursively for Arduino projects to check.

Default: false

Save a JSON formatted report on the checks to this file.

Set to true to show more information in the log about the checks being run.

Default: false

GitHub access token used to get information from the GitHub API.

Default: GITHUB_TOKEN

The minimal workflow to run the default checks on the projects in the repository:

on: [push, pull_request]
jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: arduino/arduino-lint-action@v2

A more complex workflow which uses inputs to configure the action for Library Manager "update" mode and strict compliance:

on: [push, pull_request]
jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: arduino/arduino-lint-action@v2
        with:
          library-manager: update
          compliance: strict
