| # Automatically add a label to PRs based on the [Label] prefix in the title | |
| # | |
| # Usage: | |
| # - PR title must start with a [Label] prefix in brackets | |
| # - Example: "[BugFix] Fix memory leak" will add the "BugFix" label | |
| # - Fails if no valid prefix is found | |
| # - Labels are ONLY ADDED, never removed (preserves manual labels) | |
| # | |
| # Supported prefixes (supports common variations): | |
| # - [BugFix], [Bugfix] → BugFix | |
| # - [Feature], [Features] → Feature | |
| # - [Doc], [Docs], [Documentation] → Documentation | |
| # - [Refactor], [Refactoring] → Refactoring | |
| # - [CI] → CI | |
| # - [Test], [Tests] → Tests | |
| # - [Environment], [Environments] → Environments | |
| # - [Data] → Data | |
| # - [Performance], [Perf] → Performance | |
| # - [BC-Breaking], [BCBreaking] → bc breaking | |
| # - [Deprecation], [Deprecated] → Deprecation | |
| # - [Quality] → Quality | |
