GRASS GIS Development Subversion repository

How to get write access here?

Write access is only granted to developers who agree to abide by RFC2 - Legal aspects of code contributions and the code submission guidelines

This needs to be communicated to a GRASS developer. S/he will then possibly propose you to the GRASS Project Steering committee after a period of evaluation. For details, see here

Once write access is granted, you, the new developer need to obtain an osgeo_id at http://www.osgeo.org/osgeo_userid If you already have an osgeo_id but forgot it, search for it at Search at http://www.osgeo.org/cgi-bin/ldap_web_search.py

How to compile GRASS?

See INSTALL file.

Yes, you should really read INSTALL.

How to generate the 'Programmer's Manual'?

This needs doxygen (http://www.doxygen.org) and optionally Graphviz dot (http://www.research.att.com/sw/tools/graphviz/).

To build the GRASS programmer's documentation, run

make htmldocs

or to generate documentation as single html file (recommended for simple reading)

make htmldocs-single

here. This takes quite some time. The result is in lib/html/index.html which refers to further document repositories in

   lib/vector/html/index.html
   lib/db/html/index.html
   lib/gis/html/index.html

The master file is: ./grasslib.dox where all sub-documents have to be linked into.

To generate the documents in PDF format, run

make pdfdocs

An online version is available here

Docker

Build using the downloaded source code (in the directory with the source code):

    docker build -t grassgis76 .

A test run (assuming you have existing GRASS GIS location; it can be downloaded from here)

# case 1: launching in the grassdata directory in which the location is stored:
docker run -it --rm --user=$(id -u):$(id -g) --volume $(pwd):/data --env HOME=/data/ grassgis76 \
    grass --text nc_spm_08_grass7/user1 --exec g.region -p

# case 2: launching anywhere
docker run -it --rm --user=$(id -u):$(id -g) --volume /your/test/grassdata/:/data --env HOME=/data/ grassgis76 \
    grass /data/nc_basic_spm/PERMANENT --exec g.region -p

Note that the first grassgis76 is the name of the image while the second grass is the name of the executable.

To run the tests (again assuming local location):

    docker run -it --rm --user=$(id -u):$(id -g) --volume /your/test/grassdata/:/data --env HOME=/data/ -w /code/grass \
        grassgis76 grass /data/nc_basic_spm/PERMANENT --exec \
            python -m grass.gunittest.main \
                --location nc_basic_spm --location-type nc

Note: If you compiled locally before building the Docker image, you may encounter problems as the local configuration and locally compiled file are copied to and used in the Docker image. To make sure you don't have this issue, clean all the compiled files from the source code:

make distclean
