✅ HAML Lint Action

A GitHub Action to run HAML-Lint against your code and create annotations in the GitHub UI.

📄 Introduction

GitHub Actions are an amazing new tool that can dramatically improve productivity while using the GitHub platform. While it is not hard to write a custom GitHub action to run HAML-Lint on your codebase, this action takes that functionality one step further using the checks API. After the HAML Lint Action runs HAML-Lint against your code, it will create annotations that you can easily view, matched up with the offending code.

Since GitHub actions and the checks API are continually changing, it is possible that there will be breaking API changes that affect this action. If so, please open an issue and I will look into it as soon as I can.

💡 Usage

Add the following to your GitHub action workflow to use HAML Lint Action:

- name: HAML Lint
  uses: andrewmcodes/[email protected]
  with:
    file_paths: 'app/**/*.html.haml'
    fail_level: 'error'
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

It is highly recommend you tie yourself to a version and do not do the following. I promise your life will be much easier. 😇

# ❌ Danger, sometimes I break things!
uses: andrewmcodes/haml-lint-action@master

# ✅ Much better.
uses: andrewmcodes/[email protected]

📦 Example Workflow

Here is an example workflow file incorporating HAML Lint Action:

name: HAML Lint

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v1
    - name: HAML Lint
      uses: andrewmcodes/[email protected]
      with:
        file_paths: 'app/**/*.html.haml'
        fail_level: 'error'
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

💰 Available Inputs

Refer to the official haml-lint documentation for more information on the haml-lint options.

Input Parm Name	Required	Default Value	`haml-lint` option	Description	Example
bundle	false	false	no	If you want to use a version of a gem you maintain this is your best bet. NOTE: action run time will increase relative to the size of your Gemfile.	`true`
file_paths	false	`app/views/`	yes	Define the paths you wish to be linted per run. Multiple paths can be on one line by adding a space.	`'app/*/.html.haml'`
version	false	latest release	no	Define a specific version of the `haml-lint` gem.	`'0.33.0'`
additional_gems	false		no	Additional Gems can be installed via one line with spaces and commands are supported like a version.	`'rubocop-rails rubocop-performance'`
config_path	false		yes	By default, `haml-lint` will load any file with the name `.haml-lint.yml` as a configuration file. If you want to load a config file with a different name or path, specify the path.	`'config/haml-lint.yml'`
exclude_paths	false		yes	Define a list of paths to exclude from being linted.	`'app/views/home/*.html.haml'`
fail_level	false	`error`	yes	Can define `error` or `warning` to cause haml-lint to error out on.	`'warning'`

⚠️ Gotchas

Due to the GitHub Check Runs API, we can only return 50 annotations per run. See here for more info.
There is a bug with the Checks API that might cause your runs to get jumbled in the UI, but they will all still run and render annotations in the diff correctly.
You can't use --version with multiple gems. You can specify multiple gems with version requirements using gem install 'my_gem:1.0.0' 'my_other_gem:~>2.0.0'
