GRASS Addons git repository

How to get the AddOn code

Clone of the entire AddOns git repository:

git clone https://github.com/OSGeo/grass-addons.git grass_addons

How to install or remove AddOns in your GRASS installation

The simplest way to install GRASS GIS AddOns is to use the g.extension module: https://grass.osgeo.org/grass-stable/manuals/g.extension.html

How to compile AddOn code

Compilation with GRASS GIS binaries on your computer

In this case, compile GRASS AddOns modules into your installed GRASS code by setting MODULE_TOPDIR to where to the GRASS binaries are located:

make MODULE_TOPDIR=/usr/lib/grass/

Compilation with GRASS GIS core source code locally compiled

Preparations (assuming the GRASS GIS core source code being stored in $HOME/grass/ - if you have already built GRASS GIS core from source code you don't need to do this again. If adding to a binary install, the versions must match exactly. You need to git checkout the exact tag or commit used for the binary.)

# GRASS GIS core source code
./configure # [optionally flags]
make

The easiest way to compile GRASS AddOns modules into your GRASS code is by setting MODULE_TOPDIR on the fly to tell make where to find the prepared GRASS source code:

make MODULE_TOPDIR=$HOME/grass/

(adapt as needed to your /path/to/grass/). Each module/script in the GRASS AddOns git repository should have a Makefile to support easy installation.

Install then into your existing GRASS installation with

make MODULE_TOPDIR=$HOME/grass/ install

For system-wide installation this usually requires "root" privileges (so, also sudo may help).

How to submit your contributions

While read access is granted to the public, for submissions you best fork this repository, insert your AddOn or fix an existing one in a new branch and finally open a pull request.

If you aim at full write access, this must be formally requested, see here for details: https://trac.osgeo.org/grass/wiki/HowToContribute#WriteaccesstotheGRASSaddonsrepository

In either case, please note the following submitting rules: To successfully submit your GRASS GIS AddOn module here, please check

https://grass.osgeo.org/development/

Your submission must be compliant with the GRASS submission rules as found in the GRASS source code and RFC2 (Legal aspects of submission):
