git-hooks

Another shameless plug, for my git-hooks project I wrote a few years ago https://github.com/icefox/git-hooks It is a single small bash script with no external depenandancies so it just needs to be in your path. git-hooks provide a way to manage and share your hooks using three+ locations: User hooks, installed in ~/.git_hooks/ Project hooks, installed in .git/git_hooks/ in a project. Global hooks, specified with the hooks.global configuration option. Another very real problem with any hooks solution is that it must be enabled in each repository. Users frequently either don't do it or forget to do it in all of the repositories. Running git hooks --installglobal will force any new git repository or any git repository you clone to have a reminder to install git hooks. (It can't be on by default for security reasons of course.)

Whenever I introduce a bug that could have been caught automatically I either add the missing unit test or I add a new git hook (there is of course a hook to run unit tests). From missing license files, build failures, to just spelling mistakes in the commit message there is no reason for these to exists in the repository. I created https://github.com/icefox/git-hooks to manage hooks across repositories, users, and system wide. For example if in a project I add a new hook making sure I never commit an invalid xml file, all repos that have xml files will get the hook for free.
