Subversion

The GRASS GIS software lives in the ​Subversion source control system. It can be browsed online using the ​Browse Source button on the top bar.

With the subversion client software installed, the current development version can be extracted using the command:

  svn checkout https://svn.osgeo.org/grass/grass/trunk grass

To extract the current stable version use the command:

  svn checkout https://svn.osgeo.org/grass/grass/branches/releasebranch_6_2 grass62

Update access to the Subversion repository is governed by ​RFC 2: Legal aspects of code contributions. Commiters should take care to use https for access, and use their ​OSGeo Userid for authentication. A commit command might look something like:

  svn commit -m "Distinguish between raster and vector backends (bug #999)" main.c --username glynn
