Source Code Repository Access

OpenSimulator uses git as its source code repository. Checkout

git clone git://opensimulator.org/git/opensim

See Source Code Repository for more details.

See Using Git for more Details on installing and using GIT with OpenSimulator.org

You can also browse the source code for OpenSim using a web browser.

We have Ohloh page, which takes various statistics of the OpenSimulator code base.

This is also an opensim-libs git repository which contains the source code to some of the 3rd party libraries built and included in OpenSim.

Submitting Patches

Please review Submitting code to OpenSim

Feature Proposals

Please see the Feature Proposals page.

Communication

A good first point of contact is the OpenSim IRC, on irc.freenode.net channels #opensim / #opensim-dev / #osgrid / #opensim-scripting. The OpenSim developers hold office hours once a week in-world on Tuesdays at "Wright Plaza" on OSGrid. There is a "Test Hour" on Saturdays, also generally on "Wright Plaza". Both these weekly events are held at 1900UTC in summer time and 2000UTC in winter. Check on the #opensim IRC channel on Freenode just before each of these events if there is any confusion.

There is also a mailman email distribution list available at https://lists.berlios.de/mailman/listinfo/opensim-dev
