How to use `runif:` to check git last commit message

Question & Answer

Hi @iamfabiomilano,

Thanks for asking this question here! :wink:

So, the thing about the run_if statements is that those can’t do any computation, only “flag” checks (e.g. .IsBuildFailed) and Environment Variable comparisons.

What you can do is to combine this with e.g. a Script step, where you can do any computation you need, and then expose an Environment Variable from that Script step.

After that you can check whether an environment variable is equal to a value with run_if: '{{enveq "TEST_KEY" "test value"}}' (https://github.com/bitrise-io/bitrise/blob/master/_examples/experimentals/templates/bitrise.yml#L25)
