Standard Ruby GitHub Action

A GitHub Action to run Standard Ruby against your code. Here's what it does:

1. Runs bundle exec standardrb --fix on the root directory of your repo
2. If any errors were auto-fixable, it commits those changes back to the repo
3. If any errors remain, it fails the build with annotations for each failure

Usage

Creating a Standard Ruby workflow:

To separate Standard Ruby linting and formatting from your main test suite, you can add it in a standalone workflow:

name: Standard Ruby

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    permissions:
      checks: write
      contents: write
    steps:
    - name: Standard Ruby
      uses: standardrb/standard-ruby-action@v1

Adding to an existing workflow:

You can add the following to your existing GitHub Action workflow:

- name: Standard Ruby
  uses: standardrb/standard-ruby-action@v1

This will require you to add these permissions at the top-level of your workflow (for example, after specifying the operating system via runs_on):

runs-on: ubuntu-latest
permissions:
  checks: write
  contents: read

Options

• ruby-version - If your project has a .ruby-version file, this Action will use that version of Ruby. If not, this will be forwarded to the ruby/setup-ruby action, so it takes the same values.
• autofix - If set to false, the action will not attempt to auto-fix any errors. Defaults to true.
• workdir - If set the action will descend to this directory before running bundle exec standardrb … and other relevant setup commands. Defaults to ..

Example with options set:

- name: Standard Ruby
  uses: standardrb/standard-ruby-action@v1
  with:
    ruby-version: '3.3'
    autofix: false
    workdir: my/app/subdirectory

Screenshots

[Update 6/17/2024: the current v1 release doesn't produce annotations like this, unfortunately. See #16]
