This version of Learn Prolog Now! embeds SWI SH , SWI-Prolog for SHaring. The current version rewrites the Learn Prolog Now! HTML on the fly, recognising source code and example queries. It is not yet good at recognising the relations between source code fragments and queries. Also Learn Prolog Now! needs some updating to be more compatible with SWI-Prolog. All sources are on GitHub:
