Subversion GRASS main source code repository

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, various versions can be accessed:

GRASS 7

The new development version of GRASS 7 can be extracted using the command:

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

GRASS 6.4

To extract the current development branch version of GRASS 6 (leading to 6.4.0 stable) use the command:

  svn checkout https://svn.osgeo.org/grass/grass/branches/develbranch_6 grass6_devel

If you have a local trunk version and want to continue with GRASS 6 development, read here to easily switch to this GRASS 6.4 development branch.

GRASS 6.3

To extract the current release branch version (technology preview) use the command:

  svn checkout https://svn.osgeo.org/grass/grass/branches/releasebranch_6_3 grass63_release

GRASS 6.2

To extract the old stable version use the command:

  svn checkout https://svn.osgeo.org/grass/grass/branches/releasebranch_6_2 grass62_release

Note: Write access to the Subversion repository is governed by ​RFC 2: Legal aspects of code contributions. Committers should take care to use https for access, and use their ​OSGeo Userid for authentication.

Comitting code to SVN (developers with write access)

A commit command might look something like:

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

After your first commit SVN will remember your OSGeo user id and password so --username only has be used the first time.

To add a new directory, please use (after checking that tmp files were removed and file permissions are appropriate):

  svn add newdir
  svn commit -m "New xyz functionality uploaded" newdir

Subversion GRASS Addons source code repository

With the subversion client software installed, the current GRASS Addons can be extracted using the command:

  svn checkout https://svn.osgeo.org/grass/grass-addons grass-addons

Update access to the Subversion Addons repository is governed by ​RFC 2: Legal aspects of code contributions. Committers 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 "Stereo DEM creation" main.c --username glynn

After your first commit SVN will remember your OSGeo user id and password so --username only has be used the first time.

To add a new directory, please use (after checking that tmp files were removed and file permissions are appropriate):

  svn add newdir
  svn commit -m "New xyz functionality uploaded" newdir
