Implements issue #93 by adding two new optional input parameters to validate that commit author name and email match the GitHub user profile.

New Features

author-name-match-github

• Description: Validates that the committer name matches the authenticated GitHub user's profile name
• Default: false (disabled by default)
• Requires: GITHUB_TOKEN environment variable

author-email-match-github

• Description: Validates that the committer email matches the authenticated GitHub user's profile email(s)
• Default: false (disabled by default)
• Requires: GITHUB_TOKEN environment variable

Usage Example

- name: Commit Check
  uses: commit-check/commit-check-action@v1
  with:
    author-name-match-github: true
    author-email-match-github: true
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Implementation Details

The feature adds GitHub API integration to:

1. Extract committer information from the latest git commit using git log --pretty=format
2. Compare against the authenticated GitHub user's profile via GitHub API
3. Check both primary email and verified public emails for email validation
4. Report validation errors alongside existing commit-check results
5. Handle edge cases like private emails and API permission issues gracefully

Backward Compatibility

• Both new parameters default to false, ensuring no breaking changes
• Existing functionality remains unchanged
• Only activates when explicitly enabled by users

Error Handling

• Validates GITHUB_TOKEN is present when features are enabled
• Gracefully handles API permission issues for private email access
• Provides clear error messages for validation failures
• Integrates error reporting with existing result file system

This enhancement helps teams enforce committer identity verification while maintaining the existing commit validation workflow.
