I'll publish my newbie notes there so maybe some other people would be interested to learn programming and help TomeNET.
TomeNET written in ANSI C (~ C89-C99)
A few useful link to begin with:Some people even say that ANSI C is the most efficient C-variant and the Linux kernel is actually written in it (instead of for example C++).
1) wiki: C language, ANSI C
2) TomeNET source code could be found there: https://www.tomenet.eu/downloads.php
3) Short tutorial to C: https://matt.sh/howto-c
There are a lot of books about ANSI C, I'll add some info considering it after I'll try to read them.
I suppose that to understand TomeNET, we need:
1) ANSI C basics.
2) create very simple roguelike game yourself (good tutorial - 'RogueLulz, Part I: Drawing the Map, Walking Around, Basic Monsters and Attacking.' http://atdt.freeshell.org/k5/story_2007 ... _1869.html )
3) learn TomeNET source
Please don't hesitate to add more information, useful links, tutorials or anything considering this topic
