When a new contributor opens a PR, they are asked to sign the CLA before their contribution can be merged. + +## Implementation + +This repository uses the **GitHub Action version** of CLA Assistant, which is the recommended modern approach. The implementation consists of: + +### 1. GitHub Workflow (`.github/workflows/cla.yml`) + +The workflow is triggered on: +- New pull requests (`pull_request_target`) +- PR updates (synchronize, close) +- Comments on PRs (`issue_comment`) + +**Key Features:** +- Automatically checks CLA status on every PR +- Responds to signature comments +- Stores signatures in the repository itself (in `signatures/version1/cla.json`) +- Excludes bot accounts automatically + +### 2. CLA Document (`CLA.md`) + +The actual Contributor License Agreement that contributors must accept. This document: +- Grants copyright and patent licenses +- Ensures contributors have the right to submit their code +- Protects both contributors and the project + +### 3. Contributing Guidelines (`CONTRIBUTING.md`) + +Instructions for contributors on how to sign the CLA. + +## Configuration Details + +### Workflow Configuration + +```yaml +path-to-signatures: 'signatures/version1/cla.json' +path-to-document: 'https://github.com/gradientspace/geometry3Sharp/blob/master/CLA.md' +branch: 'master' +allowlist: 'bot*,dependabot*,*[bot]' +``` + +- **Signatures**: Stored in the `master` branch at `signatures/version1/cla.json` +- **CLA Document**: Links to the CLA.md file in the repository +- **Branch**: Uses the `master` branch for storing signatures (must not be protected) +- **Allowlist**: Automatically exempts bot accounts + +### Required Secrets + +The workflow requires the following GitHub secrets: + +1. **GITHUB_TOKEN** (automatically provided by GitHub) + - Used for all CLA operations + - No manual configuration needed + +**Note**: The PERSONAL_ACCESS_TOKEN is NOT required for this setup since signatures are stored in the same repository. + +## How It Works + +1. **New PR Created**: When someone opens a pull request, the workflow runs automatically. + +2. **CLA Check**: The bot checks if the contributor has already signed the CLA. + +3. **Request Signature**: If not signed, the bot posts a comment asking the contributor to sign. + +4. **Contributor Signs**: The contributor comments: `I have read the CLA Document and I hereby sign the CLA` + +5. **Signature Recorded**: The bot records the signature in `signatures/version1/cla.json` + +6. **Status Updated**: The PR status is updated to show CLA compliance. + +## Maintenance + +### Updating the CLA + +If you need to update the CLA document: + +1. Update `CLA.md` with the new terms +2. Update the version in the workflow file: `path-to-signatures: 'signatures/version2/cla.json'` +3. All contributors will need to re-sign under the new version + +### Manually Adding Signatures + +If needed, you can manually add a signature to `signatures/version1/cla.json`: + +```json +{ + "signedContributors": [ + { + "name": "username", + "pullRequestNo": 123, + "comment_id": 456789, + "created_at": "2026-01-09T15:00:00Z" + } + ] +} +``` + +### Allowlist Management + +To exempt specific users from signing the CLA, update the `allowlist` in `.github/workflows/cla.yml`: + +```yaml +allowlist: 'bot*,dependabot*,*[bot],specific-user' +``` + +## Alternative: Hosted CLA Assistant + +This repository uses the GitHub Action version, but you can also use the hosted service at [cla-assistant.io](https://cla-assistant.io). + +**To switch to the hosted version:** + +1.
