Use this GitHub action to add voting to your projects. 🚀

Traditionally, most repositories need some number of approvers to make a change and it's not clear what to do with controversial changes such as with standards changes such as a change to linter formatting.

This GitHub action was created to allow projects to require a vote to pass before letting a pull request be mergeable.

When a Pull Request is made to your repository's main branch, a new comment is posted by the action that shows the status of the vote (which will generally be a not passing vote).

Approvals or Requesting Changes on the Pull Request is the mechanism to cast a vote. Although, only configured voters are counted. Failed votes will list the reasons why the vote failed in the action's error messaging.

When a Pull Request is update, it will clear the vote as the Pull Request reviews are cleared.

This Github action requires the ability to read/write comments on Pull Requests (Issues api).

All potential voters will need to be able to post Pull Request reviews, this should be safe after you have integrated git-democracy as it will be what blocks merge approvals.

Under Settings > Actions > General (ex: https://github.com/<org>/<repo>/settings/actions)

Follow documentation here: https://docs.github.com/actions/reference/authentication-in-a-workflow#modifying-the-permissions-for-the-github_token

(Please contribute if you've done this)

Create a new workflow in .github/workflows/ as a new .yaml file.

name: 'Voting'
on:
  pull_request_target:
    types: [opened, synchronize, reopened, closed]

jobs:
  democracy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Evaluate vote
        uses: myyk/git-democracy@v2

The name of the workflow must be Voting to match the badge that will be linked to the voting comment.

It's important that the workflow runs as triggered by pull_request_target and not pull_request so that a vote cannot be circumvented by a Pull Request containing changes to the rules of voting.

It's recommended to set your repository's branch settings to require the voting as part of the Branch protection rules by enabling Require status checks to pass before merging at a minimum enabling it for your new workflow. It may need a little time after running the action before the new workflow is selectable in the UI.

The configurations should be in the workflow definition's folder to get protections from being run with different configurations from a pull requester (with using pull_request_target trigger).

The default location is to be in the same directory as the action's definition for composite actions. For everything else, the location must be specified manually using the configPath parameter.

with:
  configPath: .github/workflows

The action expects a .voting.yml defining the rules of voting.

percentageToApprove is the percentage of weighted votes needed to approve a vote defined by the number of weighted for votes over the total number of weighted vote. This number must be above 0 for this action to have any affect.

minVotersRequired is the minimum number of unique voters need to call the results of a vote. These voters can be for or against. This number must be above 1 for the action to have any affect.

minVotingWindowMinutes is the minimum amount of time that must pass after the voting comment is created before any vote can pass.

Example:

---
percentageToApprove: 75
minVotersRequired: 3
minVotingWindowMinutes: 7200

The action expects a .voters.yml defining the voters and their vote weights.

Each entry should have the format of <github-user>:<voting-weight>. In a normal fair election, every voter has would be configured to have a weight of 1.

---
myyk: 1
jienormous: 1

Please do not use v1 tag as it is not secure since a pull requester could overwrite your .voters.yml and .voting.yml files.

Easy upgrade steps:

1. Move your .voters.yml and .voting.yml files into your .github/workflows/ directory somewhere.
2. Make sure all your voters are also Pull Requesters in your repo/org/account settings.
3. Update uses: myyk/git-democracy@v1 -> uses: myyk/git-democracy@v2
