SWI-Prolog: A comprehensive Prolog implementation

Forking, cloning and submitting patches

This repository uses many Git submodules. This causes the common issue that fork and clone doesn't work. Instead, clone from https://github.com/SWI-Prolog/swipl-devel.git and then associate your clone with your fork (replace me with your github user name).

git clone https://github.com/SWI-Prolog/swipl-devel.git
cd swipl-devel
git submodule update --init
git remote add myfork git@github.com:me/swipl-devel.git

See How to submit a patch for details.
