= How-To Code Your Own GRASS extension = Want to write your own GRASS code? Read on! == Code examples == For a beginner, the usual approach is to find a similar module and use that as a template. * Template for raster module: source:grass/trunk/doc/raster/r.example/ * example for pixel oriented raster module: source:grass/trunk/raster/r.patch * example for pixel oriented time series raster module with segmentation: source:grass/trunk/raster/r.series * example for full map oriented raster module with segmentation: source:grass/trunk/raster/r.cost * example for statistics oriented raster module: source:grass/trunk/raster/r.resamp.stats * Template for vector module: source:grass/trunk/doc/vector/v.example/ * example for vector module with database support: source:grass/trunk/vector/v.extract/ * example for topology oriented vector module: source:grass/trunk/vector/v.edit/ * Shell script templates: please take a look at existing scripts at source:grass/branches/develbranch_6/scripts/ * Python script templates: please take a look at existing scripts at source:grass/trunk/scripts/ Of course all existing modules and libraries are examples to look at. == GRASS Programmer's Manual == [http://download.osgeo.org/grass/grass6_progman/ GRASS Programmer's Manual] == Further notes == See http://grass.gdf-hannover.de/wiki/Development (should be moved here) == Good programmer?
