| Git makes it very easy to maintain local customisations to Moodle alongside updates from the official Moodle repository.
| | {{Moved_to_dev_docs}} |
| This page assumes you installed Moodle following [[Installing Moodle from Git repository]]. It also assumes you understand basic version control principles (repositories, branches, conflicts) and have a basic working knowledge of Git.
| |
| | |
| From your moodle directory, create a new branch for developing your customisation, and move to that branch:
| |
| git checkout -b myfeature
| |
| | |
| Switched to a new branch 'myfeature'
| |
| This will give you a seperate copy of the Moodle code to work on without affecting the master branch. It's not recommended that you do this on your production server, as it will cause the code to be available immediately as it's saved.
| |
| | |
| Do your customisations, add any new files to git, and commit the changes
| |
| git add .
| |
| git status
| |
| git commit -m "Description of the change"
| |
| | |
| ''Ouch! this next bit is a really bad idea. I don't know what you are trying to achieve, but this is not the right way to do it!!!--[[User:Tim Hunt|Tim Hunt]] 09:09, 15 March 2011 (UTC)''
| |
| Switch back to the master branch and merge the changes
| |
| git checkout master
| |
| git merge myfeature
| |
| Any future development can take place on the myfeature branch, and be merged into master in this way
| |
| | |
| Even after local modifications have been made, you can pull in updates from the official git repository
| |
| git checkout master
| |
| git fetch
| |
| git merge origin/master
| |
| | |
| === Conflicts ===
| |
| If you create a local modification to a file, and that same file is modified in the official repository, you may find that a conflict is created when you do <tt>git merge origin/master</tt>.
| |
| | |
| To resolve this, you will need to find the conflicts (the attempt to merge will tell you where they are) and resolve them. The [http://www.kernel.org/pub/software/scm/git/docs/git-merge.html|<tt>git merge</tt> man page] has more information on the presentation and resolution of conflicts.
| |
| | |
| After the conflict is resolved, you'll need to commit the resolved files.
| |
| git commit -a
| |
