[Freeciv-Dev] (PR#18260) Configuration files in LUA

["Jerome Plut" <Jerome.Plut@xxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=18260 >

Hi,

here is a patch that changes the configuration file so that they use
LUA instead of the traditional ruleset syntax.

Advantages of these are:
 (a) it is a Turing-complete language, so that you can modularize and
 factorize a lot of code;
 (b) it will (let's hope) allow the end-user to write more easily some
 mods entirely in LUA, given the fact that she is granted access to
 a lot of game variables;
 (c) same as (b), but for the AI.

Inconvenients:
 (d) Obviously, this completely breaks ruleset compatibility. I've
 translated the default ruleset as an example (and all the nations!)
 in the attached file, and can provide my Perl scripts to help anyone
 who has some ruleset to translate.
 (e) (Temporary) This does not change the ruleset parser being used
 for reading savegames.
 (f) (Less easy to change...) This does not change the ruleset parser
 being used for reading tilespecs.

As a first application of (a), I've included a nice way of
automatically adding the nation incompatibilities due to semblable
flags, so that it ensures that it is an equivalence relationship; see
data/default/nations.lua.

This patch seems to work (works fine for me), but certainly you will
experience problems running it; let me know so that I can fix it.
