08:53 LunaVorax Hello!
08:54 Calinou hi
08:55 LunaVorax I took a look at the Minetest source code
08:56 LunaVorax I still wonder why the map generator has been rewritten in Lua
08:56 Calinou it isn't
08:56 LunaVorax There's a mapgen.lua
08:56 Calinou minor parts of the mapgen (eg. papyrus, ore, clay) is in lua; the rest is in cpp
08:57 LunaVorax Why isn't it all in Cpp or C? Since it's a critical part of the software.
08:57 * Calinou facepalms
08:57 Calinou lua is moddable
08:57 Calinou if you want you can tweak papyrus frequency or ore frequency
08:57 Calinou in C++ you have to recompile
08:57 sfan5 <Calinou> lua is moddable >> C is too but not platform independ
08:58 Calinou the "base" mapgen is now faster; but the additional mapgen makes it slower though
08:58 Calinou (and unfortunately, it is less varied too)
08:58 sfan5 you need to have windows/mac/linux builds of your "mod" if you use C/c++
08:58 LunaVorax sfan5, isn't it supposed to be if you code right?
08:58 Calinou ^ yeah, and that sucks
08:58 Calinou you can't install several mods; they conflict
08:59 Calinou LunaVorax, try compiling on windows/mac
08:59 Calinou good luck
08:59 sfan5 <Calinou> you can't install several mods; they conflict
08:59 sfan5 thats because minecraft has modloader and so on
08:59 Calinou even worse compared to MC
09:01 sfan5 yeah
09:01 sfan5 minecraft modding: platform independ .class files
09:02 sfan5 minetest modding (C/C++): NOT platform independ .exe or other files
09:02 sfan5 lua is the best
09:02 Calinou minecraft modding still requires compilation; this lets modders make their mods proprietary (they should, anyway, as MC itself is proprietary, else it's illegal)
09:02 Calinou redistributing compiled mods is illegal anyway; unless they're patches
09:03 Calinou and lua is also less half assed.
09:03 Calinou it isn't fast, but it's not about "com.com.package.org.org.org.org.asm.​NullPointerException.macos.winblows"
09:04 sfan5 java is slow...
09:05 thexyz lua is fast enough to write mods in it
09:07 Calinou yeah
09:07 Anchakor java is fast http://shootout.alioth.debian.org/u64q/wh​ich-programming-languages-are-fastest.php
09:07 Calinou java is faster than lua though iirc
09:08 Anchakor yup
09:08 Calinou lua is bytecode iirc, no?
09:11 LunaVorax It compiles on the fly?
09:12 Calinou not sure
09:12 thexyz bytecode != compiled code
09:12 thexyz "compiles of the fly" == jit
09:13 LunaVorax ok
09:14 LunaVorax I'm not familiar with theses terms yet
09:17 Calinou k
09:18 Calinou is JIT used by default?
09:18 Calinou for minetest
09:18 Anchakor "compiles on the fly" == interpreted, not matter if using JIT compilation or not
09:19 thexyz Calinou: no
09:19 thexyz lua itself doesn't support jit
09:19 thexyz there is, though, luajit
09:29 Calinou k
