githook to validate newly created branch names

Question

Does anyone know if there\'s a githook that will hook into the creation of a branch in order to reject the branch name before it\'s actually created?

I currently use com

Answer 1

There is not (and to some extent it can't be controlled: branch names are transferred across the network during fetch and push, via refspecs, and refspecs are somewhat limited).

There is a git command, git check-ref-format; its documentation describes what Git allows. (Branch names are simply any reference that starts with refs/heads/.)

The only place you can mandate anything at all is in your own repositories. In your pre-receive exit,

while read old new ref; do 
    yourtesthere "$ref" || { rc=1; echo "$ref failed yourtesthere's validation"; }
done
exit $rc

and no one can push a bad refname to your repository. A command to check a name before passing it along to git is down in alias / oneliner territory.

You can distribute the yourtesthere command, of course, and anyone that wants can use it to test branch names in their own repositories, but just as your repositories are yours, their repositories are theirs.

Seems like you are referring to placing a policy for commits or branch creation. There is a git config command which helps in putting some template in place eg:

$ git config --global commit.template ~/.template.txt $ git commit

subject line

Sorry if this did not help. Thanks.
