Hello, Is there a complete list of “When” conditions documented anywhere? (or a link to the code, I had a look but couldn’t find it). By this, I mean, what options you can put in the “when” conditions on each step i.e event, branch, ref, status etc Many thanks! ---

Hi @microadam, here is the documentation for step conditions: [http://docs.drone.io/step-conditions/](http://docs.drone.io/step-conditions/) There are also pipeline conditions (apply to all steps): [http://docs.drone.io/pipeline-conditions/](http://docs.drone.io/pipeline-conditions/) Please take a look and send a PR if you feel like something is missing. ---

Hi @tonglil. Yes, I am aware of those pages. However that literally only mentions `branch` and `event`. I am aware of others (only through seeing people mention things in discourse) such as `ref` and `status`, but I was hoping to find out a FULL list (unless those are literally the only 4 things available?). Happy to look through code for the list if needs be, but I am not a GO developer so wasn’t sure where I should be looking. If you could point me in the right direction, that would be great ---

Here are the constraints and some tests for them: > > As far as I can tell, the documentation contains info for - Branches: [http://docs.drone.io/step-conditions/#branches](http://docs.drone.io/step-conditions/#branches) - Events: [http://docs.drone.io/step-conditions/#events](http://docs.drone.io/step-conditions/#events) - Status: [http://docs.drone.io/step-conditions/#status](http://docs.drone.io/step-conditions/#status) - Platform: [http://docs.drone.io/step-conditions/#platform](http://docs.drone.io/step-conditions/#platform) - Environment: [http://docs.drone.io/step-conditions/#environment](http://docs.drone.io/step-conditions/#environment) - Matrix: [http://docs.drone.io/step-conditions/#matrix](http://docs.drone.io/step-conditions/#matrix) - Instance: [http://docs.drone.io/step-conditions/#instance](http://docs.drone.io/step-conditions/#instance) There is no documentation for refs as mentioned in “[Execute a build step only when a feature branch is tagged with a specific pattern?](http://discuss.harness.io/t/execute-a-build-step-only-when-a-feature-branch-is-tagged-with-a-specific-pattern/1237)”. Feel free to send a PR to the docs about that one! ---

Have the docs recently been updated? As I swear all that information wasn’t there last time I looked! Apologies for the oversight… I must be going mad. Many thanks for all the links. Good to know that is the full list. ---

In drone 1.0.0, the URL changed for the “when” conditions. They now live here: [https://docs.drone.io/user-guide/pipeline/conditions/](https://docs.drone.io/user-guide/pipeline/conditions/) ---
