Workflows

Workflows for use by maintainers. These should be run from your fork of this repository, with an encrypted secret called ACCESS_TOKEN that is a personal access token with repo and workflow scopes.

PR Script

The PR Script Workflow allows you to make a commit against a PR as a maintainer without having to check out the PR locally and push the change. The manual workflow takes as its inputs a link to the PR and a comma-separated list of quoted commands to run. As a convenience, you can also type "True" for the option to run pre-commit against the PR to fix up any pre-commit errors.

Actions

Base Setup

Use this action to consolidate setup steps and caching in your workflows. You can control the versions of Python and Node used by setting matrix.python-version and matrix.node-version, respectively. An example workflow file would be:

name: Tests
on:
  push:
    branches: "main"
  pull_request:
    branches: "*"
jobs:
  build:
    runs-on: ubuntu-latest
  steps:
    - name: Checkout
      uses: actions/checkout@v2
    - name: Base Setup
      uses: jupyterlab/maintainer-tools/.github/actions/base-setup@v1
    - name: Install
      shell: bash
      run: pip install -e ".[test]"
    - name: Test
      shell: bash
      run: pytest

Enforce Labels

Use this action to enforce one of the triage labels on PRs in your repo (one of documentation, bug, enhancement, feature, maintenance). An example workflow file would be:

name: Enforce PR label

on:
  pull_request:
    types: [labeled, unlabeled, opened, edited, synchronize]
jobs:
  enforce-label:
    runs-on: ubuntu-latest
    steps:
      - name: enforce-triage-label
        uses: jupyterlab/maintainer-tools/.github/actions/enforce-label@v1

Test Downstream Libraries

Use this action to test a package against downstream libraries. This can be used to catch breaking changes prior to merging them. An example workflow file would be:

name: Downstream Tests
on:
  push:
    branches: "main"
  pull_request:
    branches: "*"
jobs:
  build:
    runs-on: ubuntu-latest
  steps:
    - name: Checkout
      uses: actions/checkout@v2
    - name: Base Setup
      uses: jupyterlab/maintainer-tools/.github/actions/base-setup@v1
    - name: Test Against Foo
      uses: jupyterlab/maintainer-tools/.github/actions/downstream-test@v1
      with:
        package_name: foo
    - name: Test Against Bar
      uses: jupyterlab/maintainer-tools/.github/actions/downstream-test@v1
      with:
        package_name: bar
        env_values: "FIZZ=buzz NAME=snuffy"

PR Binder Link

Use this action to add binder links for testing PRs, which show up as a comment.
You can use the optional url_path parameter to use a different url than the default lab. An example workflow would be:

name: Binder Badge
on:
  pull_request_target:
    types: [opened]

jobs:
  binder:
    runs-on: ubuntu-latest
    permissions:
      pull-requests: write
    steps:
      - uses: jupyterlab/maintainer-tools/.github/actions/binder-link@v1
        with:
          github_token: ${{ secrets.github_token }}

PR Script

You can use the PR Script action in your repo along with pull-request-comment-trigger to enable maintainers to comment on PRs to run a script against a pull request. The script can only be run by a org member, collaborator, or repo owner if the association parameter is used (as in the examples below).

Note that the resulting commit will not trigger the workflows to run again. You will have to close/reopen the PR, or push another commit for the workflows to run again. If this behavior is not desirable, you can use a personal access token instead of the default GitHub token provided to the workflow. Make sure the token used is of as limited scope as possible (preferrably a bot account token with access to the public_repo scope only).

This first example allows maintainers to run pre-commit by commenting "auto run pre-commit" on a Pull Request.

name: Trigger Pre-Commit on a PR
on:
  issue_comment:
    types: [created]

permissions:
  contents: write
  pull-requests: write

jobs:
  pr-script:
    runs-on: ubuntu-latest
    steps:
      - uses: khan/[email protected]
        id: check
        with:
          trigger: "auto run pre-commit"
      - if: steps.check.outputs.triggered == 'true'
        uses: jupyterlab/maintainer-tools/.github/actions/base-setup@v1
      - if: steps.check.outputs.triggered == 'true'
        uses: jupyterlab/maintainer-tools/.github/actions/pr-script@v1
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          pre_commit: true
          commit_message: "auto run pre-commit"
          target: ${{ github.event.issue.html_url }}
          association: ${{ github.event.comment.author_association }}

In this example, the repo has a custom script that should be run, which is triggered by a PR comment "auto run cleanup". Again, this can only be run by a org member, collaborator, or repo owner.

name: Trigger a Cleanup Script on a PR
on:
  issue_comment:
    types: [created]

permissions:
  contents: write
  pull-requests: write

jobs:
  pr-script:
    runs-on: ubuntu-latest
    steps:
      - uses: khan/[email protected]
        id: check
        with:
          trigger: 'auto run cleanup'
      - if: steps.check.outputs.triggered == 'true'
        uses: jupyterlab/maintainer-tools/.github/actions/base-setup@v1
      - if: steps.check.outputs.triggered == 'true'
        uses: jupyterlab/maintainer-tools/.github/actions/pr-script@v1
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          script: "[\"jlpm run integrity\", \"jlpm run lint\"]"
          commit_message: "auto run cleanup"
          target:  ${{ github.event.issue.html_url }}
          association: ${{ github.event.comment.author_association }}

Update snapshots

You can use update snapshots action to commit on a branch Playwright updated snapshots.

The requirements and constrains are:

You must be on the branch to which the snapshots will be committed
You must installed your project before calling the action
The action is using yarn package manager
The Playwright tests must be in TypeScript or JavaScript

An example of workflow that get triggered when a PR comment contains update playwright snapshots would be:

name: Update Playwright Snapshots

on:
  issue_comment:
    types: [created, edited]

permissions:
  contents: write
  pull-requests: write

jobs:
  update-snapshots:
    if: ${{ github.event.issue.pull_request && contains(github.event.comment.body, 'update playwright snapshots') }}
    runs-on: ubuntu-latest

    steps:
      - name: Checkout
        uses: actions/checkout@v2

      - name: Checkout the branch from the PR that triggered the job
        run: |
          # PR branch remote must be checked out using https URL
          git config --global hub.protocol https
          hub pr checkout ${{ github.event.issue.number }}
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

      - name: Install your project
        run: |
          # Execute the required installation command

      - name: Update snapshots
        uses: jupyterlab/maintainer-tools/.github/actions/update-snapshots@v1
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          # Test folder within your repository
          test_folder: playwright-tests

          # Optional npm scripts (the default values are displayed)
          # Script to start the server or 'null' if Playwright is taking care of it
          #   If not `null`, you must provide a `server_url` to listen to.
          start_server_script: start
          # Server url to wait for before updating the snapshots
          #  See specification for https://github.com/iFaxity/wait-on-action `resource`
          server_url: http-get://localhost:8888
          update_script: test:update
