If a pipeline needs complex trigger logic like: ```auto "refs/pull/**" && "refs/heads/release*" ``` Can we do this in the drone configuration? See more context at [CI: duplicate CI run with only chat notification · Issue #4460 · owncloud/ocis · GitHub](https://github.com/owncloud/ocis/issues/4460)? Note: The `starlark` language is used to generate the `yaml` config file. Thanks in advance. ---

Hey @kiran the logic you are looking for should be here - [Triggers | Drone](https://docs.drone.io/pipeline/docker/syntax/trigger/) I think a commit can only have one ref so I’m not sure your logic would work - instead you could make use of [refs](https://docs.drone.io/pipeline/docker/syntax/trigger/#by-reference) and [actions](https://docs.drone.io/pipeline/docker/syntax/trigger/#by-action) Or maybe use [branch](https://docs.drone.io/pipeline/docker/syntax/trigger/#by-branch) or [target](https://docs.drone.io/pipeline/docker/syntax/trigger/#by-target)
