| pull_request_target: | |
| # This workflow depends on the base branch of the PR, | |
| # but changing the base branch is not included in the default trigger events, | |
| # which would be `opened`, `synchronize` or `reopened`. | |
| # Instead it causes an `edited` event, so we need to add it explicitly here | |
| # While `edited` is also triggered when the PR title/body is changed, | |
| # this PR action is fairly quick, and PR's don't get edited that often, | |
| # so it shouldn't be a problem | |
| # There is a feature request for adding a `base_changed` event: | |
| # https://github.com/orgs/community/discussions/35058 | |
| types: [opened, synchronize, reopened, edited] | |
| permissions: {} | |
| # We don't use a concurrency group here, because the action is triggered quite often (due to the PR edit | |
| # trigger), and contributers would get notified on any canceled run. | |
| # There is a feature request for supressing notifications on concurrency-canceled runs: | |
