madduck's git repository

Every one of the projects in this repository is available at the canonical URL git://git.madduck.net/madduck/pub/<projectpath> — see each project's metadata for the exact URL.

All patches and comments are welcome. Please squash your changes to logical commits before using git-format-patch and git-send-email to patches@git.madduck.net. If you'd read over the Git project's submission guidelines and adhered to them, I'd be especially grateful.

SSH access, as well as push access can be individually arranged.

If you use my repositories frequently, consider adding the following snippet to ~/.gitconfig and using the third clone URL listed for each project:

[url "git://git.madduck.net/madduck/"]

+## HOOK SYSTEM
+
+`vcsh` provides a hook system. Hook scripts need to be executable and placed
+in <$XDG_CONFIG_HOME/vcsh/hooks-available>. From there, they should be
+soft-linked <$XDG_CONFIG_HOME/vcsh/hooks-enabled>.
+
+Hooks follow a simple format. `pre-run` will be run before anything is run.
+If you want to have more than one script for a certain hook, just append
+strings to order them. A system of `pre-run`, `pre-run.10`, `pre-run.20` etc
+is suggested. The dot it optional.
+
+If you want to create hooks for a specific `vcsh` repository, simply prepend
+the repository's name, followed by a dot, i.e. `zsh.pre-run`. This dot is
+mandatory.
