customising gitolite

Much of gitolite (g3)'s functionality comes from programs and scripts that are not considered "core". This keeps the core simpler, and allows you to enhance gitolite for your own purposes without too much fuss.

types of non-core programs

There are 5 basic types of non-core programs.

commands can be run from the shell command line. Those listed in the COMMANDS hash of the rc file can also be run remotely.
hooks are standard git hooks; see below.
sugar scripts change the conf language for your convenience. The word sugar comes from "syntactics sugar".
triggers are to gitolite what hooks are to git. I just chose a different name to avoid confusion and constant disambiguation in the docs.
VREFs are extensions to the access control check part of gitolite.

#commands gitolite "commands"

Gitolite comes with several commands that users can run. Remote user run the commands by saying:

ssh git@host command-name [args...]

while on the server you can run

gitolite command [args...]

Very few commands are designed to be run both ways, but it can be done, by checking for the presence of env var GL_USER.

You can get a list of available commands by using the help command. Naturally, a remote user will see a much smaller list than the server user.

You add commands to the "allowed from remote" list by adding its name (or uncommenting it if it's already added but commented out) to the COMMANDS hash in the [rc][] file.

If you write your own commands, put them in src/commands.

#hooks hooks and gitolite

Gitolite uses the update hook for all repos. In addition, it uses the post-update hook for the gitolite-admin repo.

If you want to add your own hook, it's easy as long as it's not the 'update' hook. Just add it to $HOME/.gitolite/hooks/common and run gitolite setup.

The rest is between you and 'man githooks' :-)

#sugar syntactic sugar

Sugar scripts help you change the perceived syntax of the conf language. The base syntax of the language is as described [here][conf], so sugar scripts take something else and convert it into that.

That way, the admin sees additional features (like allowing continuation lines), while the parser in the core gitolite engine does not change.

If you want to write your own sugar scripts, please read the "your own sugar" section in [dev-notes][] first then email me.

triggers

Triggers have their own [document][triggers].

VREFs

VREFs also have their own [document][vref].
