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.
