[GRASS-user] Building a new module

GRASS GRASS user
1

Hello everyone,
I have to build a new module for GRASS, but I have some doubts about what the things I have to do.

First of all, i’d need some data structure like graphs, union finds and dynamic trees. Are these structure included in GRASS?

For a beginner like me a guide that explains the building of a module (or a pattern) would be very very helpful. Could you suggest me something to ease my work?

Best regards,
Roberto

Generally, you need to provide your own data structures and associated
algorithms. There is a btree library, but that's about it.

However, as GRASS is licensed under the GPL (version 2 or later), you
can use code from other GPL or GPL-compatible (LGPL, MIT, new BSD
licences) software.

The usual approach is to find a similar module and use that as a
template.
