Sometimes it is useful to turn on checks only for certain branches and turn them off on all other branches.

YACC has the Exclude Branch Regex feature to specify a regex that can exclude branches from checks. With a little bit of regex magic, this feature can be used to only run YACC on a set of allowlisted branches.

For example, to perform checks on the branches master and release, but no other branch, configure the Exclude Branch Regex option like this:
^(?!master$|release$).*

All branch names other than master and release are excluded, and the checks only apply to those two branches.
