Verible Formatter Action

Usage

See action.yml

This is a GitHub Action used to format Verilog and SystemVerilog source files and create change suggestions in Pull Requests automatically. The GitHub Token input is used to provide reviewdog access to the PR.

Here's a basic example to format all *.v and *.sv files:

name: Verible formatter example
on:
  pull_request:
jobs:
  format:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    - uses: chipsalliance/verible-format-action@main
      with:
        github_token: ${{ secrets.GITHUB_TOKEN }}

You can provide paths argument to point files to format. Directories will be searched recursively for *.v and *.sv files. paths defaults to '.'.

- uses: chipsalliance/verible-format-action@main
  with:
    paths: |
      ./rtl
      ./shared
    github_token: ${{ secrets.GITHUB_TOKEN }}

Automatic review on PRs from external repositories

In GitHub Actions, workflows triggered by external repositories may only have read access to the main repository. In order to have automatic reviews on external PRs, you need to create two workflows. One will be triggered on pull_request and upload the data needed by reviewdog as an artifact. The artifact shall store the file pointed by $GITHUB_EVENT_PATH as event.json. The other workflow will download the artifact and use the Verible action.

For example:

name: upload-event-file
on:
  pull_request:

...
      - run: cp "$GITHUB_EVENT_PATH" ./event.json
      - name: Upload event file as artifact
        uses: actions/upload-artifact@v2
        with:
          name: event.json
          path: event.json

name: review-triggered
on:
  workflow_run:
    workflows: ["upload-event-file"]
    types:
      - completed

jobs:
  review_triggered:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: 'Download artifact'
        id: get-artifacts
        uses: actions/[email protected]
        with:
          script: |
            var artifacts = await github.actions.listWorkflowRunArtifacts({
               owner: context.repo.owner,
               repo: context.repo.repo,
               run_id: ${{github.event.workflow_run.id }},
            });
            var matchArtifact = artifacts.data.artifacts.filter((artifact) => {
              return artifact.name == "event.json"
            })[0];
            var download = await github.actions.downloadArtifact({
               owner: context.repo.owner,
               repo: context.repo.repo,
               artifact_id: matchArtifact.id,
               archive_format: 'zip',
            });
            var fs = require('fs');
            fs.writeFileSync('${{github.workspace}}/event.json.zip', Buffer.from(download.data));
      - run: |
          unzip event.json.zip
