Repository rules allow you to easily add scalable protections for branches and tags on your repositories. This feature was recently made generally available, and GitHub Desktop 3.3 now adds support for repository rules in the form of preemptive warnings and errors if your work fails a rule configured by an administrator of your repository. These rules can fail when commits are pushed to GitHub, which may not be ideal if you queue up multiple commits before pushing. Advanced warning allows you to make changes before committing, saving you time and frustration.
Administrators can configure many different repository rules that apply to branches or tags. If a commit fails any of them, you won’t be able to push it to GitHub. This can be frustrating if you have multiple commits queued up, because the whole push will fail and you may have to perform a rebase to fix the failed commits. GitHub Desktop will now preemptively warn you if a commit you’re working on will fail a rule when you eventually try to push it. These warnings happen in several ways.
Specific branch names may be disallowed. You’ll now see an error if you try to create a branch that isn’t allowed.
GitHub Enterprise Cloud customers can utilize metadata rules that require certain fields to conform to specific values. One example being commit messages, which can be required to match a specific string or a regex pattern. These metadata rules are fully supported in GitHub Desktop 3.3.
Certain rules have remediations that aren’t supported by GitHub Desktop, such as requiring status checks to pass. These rules are bundled into a catch-all error message above the commit button.
Administrators can allow certain apps, roles, or teams to bypass rulesets. If you can bypass rules, the guidance shown is in the form of warnings instead errors, to let you know to be extra careful.
GitHub Desktop is proud to be an open source project and represents both GitHub and the open source community. Thanks to @le0pard for creating the RE2JS library being used for repository rules regex matching.
