For Developers

Git read access

 

Git is the revision control system we use to collaborate on Composr.

You can access the repository on GitLab. Version 11 is on the "v11" branch.

We often commit fixes to Git before patch releases come out.

Be aware that the Git repository also has many non-bundled addons in it. We develop them in there, to keep them up-to-date. There is a script called delete_alien_files.php which will erase them. You need to first delete the sources_custom/hooks/systems/addon_registry/*.php files of any addons you don't want, then run the script, then run the commands the script says (after reviewing), then install.

Git write access

 

We accept and encourage external contributions.

We will provide write-access to Git as appropriate (essentially when someone shows a serious commitment to the project in the form of high-quality code).

Are you upgrading from a previous version 11 release?

Instead of using this page, you should login to your Admin Zone. You'll see a link to upgrade there.

We highly advise against upgrading from version 10 at this time. Version 11 is still bleeding edge and intended for testing purposes only; the upgrader will likely break your v10 site.
