Label Actions

Label Actions is a GitHub bot that performs certain actions when issues, pull requests or discussions are labeled or unlabeled.

Supporting the Project

The continued development of Label Actions is made possible thanks to the support of awesome backers. If you'd like to join them, please consider contributing with Patreon, PayPal or Bitcoin.

How It Works

The bot performs certain actions when an issue, pull request or discussion is labeled or unlabeled. No action is taken by default and the bot must be configured. The following actions are supported:

  • Post comments
  • Add labels
  • Remove labels
  • Close threads
  • Reopen threads
  • Lock threads with an optional lock reason
  • Unlock threads

Usage

  1. Create the .github/workflows/label-actions.yml workflow file, use one of the example workflows to get started
  2. Create the .github/label-actions.yml configuration file based on the example below
  3. Start labeling issues, pull requests and discussions

Inputs

The bot can be configured using input parameters.

  • github-token
    • GitHub access token, value must be ${{ github.token }} or an encrypted secret that contains a personal access token
    • Optional, defaults to ${{ github.token }}
  • config-path
    • Configuration file path
    • Optional, defaults to .github/label-actions.yml
  • process-only
    • Process label events only for issues, pull requests or discussions, value must be a comma separated list, list items must be one of issues, prs or discussions
    • Optional, defaults to ''

Configuration

Labels and actions are specified in a configuration file. Actions are grouped under label names, and a label name can be prepended with a - sign to declare actions taken when a label is removed from a thread. Actions can be overridden or declared only for issues, pull requests or discussions by grouping them under the issues, prs or discussions key.

Examples

The following workflow will perform the actions specified in the .github/label-actions.yml configuration file when an issue, pull request or discussion is labeled or unlabeled.

name: 'Label Actions'

on:
  issues:
    types: [labeled, unlabeled]
  pull_request:
    types: [labeled, unlabeled]
  discussion:
    types: [labeled, unlabeled]

permissions:
  contents: read
  issues: write
  pull-requests: write
  discussions: write

jobs:
  action:
    runs-on: ubuntu-latest
    steps:
      - uses: dessant/label-actions@v2

Available input parameters

This workflow declares all the available input parameters of the app and their default values. Any of the parameters can be omitted.

name: 'Label Actions'

on:
  issues:
    types: [labeled, unlabeled]
  pull_request:
    types: [labeled, unlabeled]
  discussion:
    types: [labeled, unlabeled]

permissions:
  contents: read
  issues: write
  pull-requests: write
  discussions: write

jobs:
  action:
    runs-on: ubuntu-latest
    steps:
      - uses: dessant/label-actions@v2
        with:
          github-token: ${{ github.token }}
          config-path: '.github/label-actions.yml'
          process-only: ''

Ignoring label events

This step will process label events only for issues.

    steps:
      - uses: dessant/label-actions@v2
        with:
          process-only: 'issues'

This step will process label events only for pull requests and discussions.

    steps:
      - uses: dessant/label-actions@v2
        with:
          process-only: 'prs, discussions'

Unnecessary workflow runs can be avoided by removing the events that trigger workflows from the workflow file instead.

on:
  issues:
    types: labeled

Configuring labels and actions

Labels and actions are specified in a configuration file. The following example showcases how desired actions may be declared:

# Configuration for Label Actions - https://github.com/dessant/label-actions

# The `heated` label is added to issues, pull requests or discussions
heated:
  # Post a comment
  comment: >
    The thread has been temporarily locked.
    Please follow our community guidelines.
  # Lock the thread
  lock: true
  # Set a lock reason
  lock-reason: 'too heated'
  # Additionally, add a label to pull requests
  prs:
    label: 'on hold'

# The `heated` label is removed from issues, pull requests or discussions
-heated:
  # Unlock the thread
  unlock: true

# The `wontfix` label is removed from issues
-wontfix:
  issues:
    # Reopen the issue
    reopen: true

# The `feature` label is added to issues
feature:
  issues:
    # Post a comment, `{issue-author}` is an optional placeholder
    comment: >
      :wave: @{issue-author}, please use our idea board to request new features.
    # Close the issue
    close: true

# The `wip` label is added to pull requests
wip:
  prs:
    # Add labels
    label:
      - 'on hold'
      - 'needs feedback'

# The `wip` label is removed from pull requests
-wip:
  prs:

    label: 'needs QA'
    # Remove labels
    unlabel:
      - 'on hold'
      - 'needs feedback'

# The `solved` label is added to discussions
solved:
  discussions:
    # Lock the discussion
    lock: true

Using a personal access token

The action uses an installation access token by default to interact with GitHub. You may also authenticate with a personal access token to perform actions as a GitHub user instead of the github-actions app.

Create a personal access token with the repo or public_repo scopes enabled, and add the token as an encrypted secret for the repository or organization, then provide the action with the secret using the github-token input parameter.

    steps:
      - uses: dessant/label-actions@v2
        with:
          github-token: ${{ secrets.PERSONAL_ACCESS_TOKEN }}
