Time  Nick          Message
02:49 hmmmm         trying something totally new *crosses fingers*
02:50 VanessaE      uh oh.
06:19 celeron55     23:35:37 < sapier> celeron setmetatabe is used for all register functions therefore it doesn't seem to  be easy to disable
06:19 celeron55     i already said how you do it
07:18 thexyz        wait, are you going to disable setmetatable for security reasons?
07:52 celeron55     yes; in lua you need to do that in order to sandbox anything
07:52 celeron55     anything that allows it is incapable of sandboxing
07:56 celeron55     or, well; i am not exactly sure if it always makes a security hole, but it definitely always allows to at least crash other code
08:47 thexyz        bad, stress won't work without it
08:47 thexyz        or, well, anything oop
08:49 thexyz        not "anything" though
08:49 thexyz        but it'll look dirtier
08:56 thexyz        being unable to redefine operators is bad too
09:04 RealBadAngel  i just replaced lualib.a with luajit, and got some error in serialization tests
09:05 RealBadAngel  its safe to skip those tests?
09:06 RealBadAngel  https://github.com/minetest/minetest/blob/master/builtin/serialize.lua#L200
09:06 RealBadAngel  this line is the problem
09:07 thexyz        just comment it out
09:10 RealBadAngel  first impressions: no lag at start, with old lua i had 4-5fps at start then slowly it was raising
09:10 RealBadAngel  now it is 50fps from the very start
09:11 RealBadAngel  world is generating faster (moreores, technic worldgen, moretrees, plantib here)
09:14 RealBadAngel  i need to compare now execution time of some technic routines
09:27 RealBadAngel  well, it is several times faster at least
09:44 RealBadAngel  maybe not several times, but way faster
09:50 RealBadAngel  http://pastebin.com/B16s5um7
09:51 RealBadAngel  comparision of Lua and LuaJit with search alorithms
09:51 RealBadAngel  execution of search repeated 100x, measured 20 times
09:52 RealBadAngel  end of story, luaJIT IS way faster
10:48 thexyz        wtf
10:48 thexyz        100 nodes, run 100 times - 1s?
10:49 thexyz        that's like 10^4 times slower than same in C i guess
10:50 celeron55     that text doesn't tell anything about what it's actually doing
10:50 thexyz        hm, yes
10:50 thexyz        i don't think it's that slow
10:50 celeron55     maybe it's depth of 100 in three dimensions, being 100^3? 8) can't know; RBA needs to tell
10:51 thexyz        well, assuming he used dfs and knowing dfs is O(N)
10:56 RealBadAngel  http://en.wikipedia.org/wiki/Breadth-first_search
10:57 RealBadAngel  it is forced to identify and find 100 connected nodes
10:57 RealBadAngel  and reapeat it 100 times in one abm call
11:02 thexyz        looks more like O(n^3) then
11:03 thexyz        so, 10^8 operations are done in ~1s which is fast
11:03 RealBadAngel  screenshot of what it is doin on its way
11:05 RealBadAngel  http://i.imgur.com/XitsGs4.jpg
11:05 celeron55     RealBadAngel: put a counter in it to count how many it actually checks
11:05 RealBadAngel  starting from battery box, find all the wire nodes, and all connected to it devices
11:05 RealBadAngel  store them in a table
11:06 RealBadAngel  instead of 1 time per abm call i repeat it 100 times for measuring purposes
11:07 celeron55     so doing that thing takes 14 or 40ms
11:07 celeron55     quite reasonable
11:08 celeron55     do you have good ways of invalidating the cache?
11:10 RealBadAngel  what do you mean exactly?
11:11 celeron55     i guess you only need to check the type of a modified node to know if you need to recalculate the cached wire network
11:11 RealBadAngel  it is not cached, it is live
11:12 RealBadAngel  table is created each time from scratch
11:12 RealBadAngel  so if i connect 2nd batbox to it, break the circuit somwhere, it will create 2 separate circuits
11:13 celeron55     that'll be quite wasteful if you make a few times larger circuit
11:13 RealBadAngel  no need to create such big circuits
11:13 RealBadAngel  and 100 is hardcoded max of a graph
11:14 RealBadAngel  something like mesecons losing signal after some distance
11:16 RealBadAngel  thx to it it is recalculated each time, devices just works on plug in and circuit is responding live on player actions
11:17 RealBadAngel  but back to measures, they show how much faster is luajit for such things
11:18 RealBadAngel  when everythin to get more than twice as fast code is to replace one lib i think its worth it
11:26 thexyz        yeah, but serialize is broken
11:27 thexyz        or maybe escape sequences work differently
11:32 RealBadAngel  its not broken
11:32 RealBadAngel  stargates working just fine
11:32 RealBadAngel  and they use serialize to store tables on disk
11:34 thexyz        yes, i mean, something is wrong with escape sequences
11:34 thexyz        i guess that's not important at all
11:34 RealBadAngel  i googled something about using % instead of /
11:34 thexyz        i wonder how should we include luajit
11:35 thexyz        like a git submodule maybe?
11:35 RealBadAngel  i just did it your way, compiled and renamed library to liblua.a
11:35 thexyz        do they have public git repo?
11:35 thexyz        that's great, but we need saner way to include it into minetesr
11:36 RealBadAngel  http://luajit.org/download.html
11:38 thexyz        good
11:46 RealBadAngel  tested stargates a bit more, seems that serialize/deserialize workin just fine
11:54 thexyz        yeah, that seems logical
11:59 RealBadAngel  i tested all my code that is using serialize, no problems at all
12:02 RealBadAngel  thexyz, btw if you want to test stargates: https://github.com/RealBadAngel/technic
12:02 RealBadAngel  theyre almost finished
12:02 RealBadAngel  need to add a few simple and easy pieces just
13:33 RealBadAngel  hi hmmmm
13:34 RealBadAngel  ive tested luajit and it is faster than lua
13:36 ecube         it would be hard to switch to luajit
13:37 RealBadAngel  not really
13:37 RealBadAngel  im switchin now there and back by copying one file and linking binaries again
13:38 RealBadAngel  ive compiled luajit and renamed the library to liblua.a
13:40 RealBadAngel  https://github.com/minetest/minetest/blob/master/builtin/serialize.lua#L200
13:40 RealBadAngel  only this line has to be fixed for luajit to work
14:21 celeron55     you should see what causes the problem on that line
14:32 RealBadAngel  unittest_input = {escapechars="\n\r\t\v\\\"\'\[\]", noneuropean="θשׁ٩∂"}
14:32 RealBadAngel  problem is \[ and \]
14:33 RealBadAngel  brackets in general
14:34 RealBadAngel  http://lua.2524044.n2.nabble.com/LuaJIT-2-0-0-beta9-and-Lua-5-1-4-different-behavior-td7175550.html
15:16 RealBadAngel  celeron55, do we need that feature?
15:21 celeron55     ah so the \[\] thing are invalid escape sequences
15:21 celeron55     remove them from there
15:22 RealBadAngel  i made it here, about replacing whole lua sources with luajit im not sure how to do that
15:23 RealBadAngel  i compiled luajit in another directory and replaced compiled .a
15:41 celeron55     lol Taoki is just silly; first goes to make jumping harder, and then wants to bloat up everything with partial blocks in order to make moving less hard: http://forum.minetest.net/viewtopic.php?id=5072
15:41 celeron55     8D
15:41 * celeron55   does not approve
16:29 VanessaE      I've been testing luajit per realbadangel's instructions.  The speedup under minetest (e.g. with moretrees) is significant.
16:29 VanessaE      it ain't the silver bullet, but it's definitely faster.
16:32 VanessaE      my server now runs this luajit build for those who want to check that out.
16:36 Calinou       *electricity company frowns at VanessaE*
16:36 VanessaE      lol
16:57 khonkhortisan Hi RealBadAngel. Where did 6d facedir go?
16:57 RealBadAngel  will be there this weekend
16:58 khonkhortisan okay
16:58 RealBadAngel  i just finished workin on stargates, tested luajit
16:58 RealBadAngel  now i can go back to 6d facedir
18:23 PilzAdam      why do we have the movement and on_demand_item_visuals branch still hanging arround in minetest/minetest
18:50 rubenwardy    can someone make me a cmakelists.txt that compiles main
18:50 rubenwardy    meh
18:50 MiJyn         compiles main?
18:50 MiJyn         what do you mean?
18:50 rubenwardy    can someone make me a cmakelists.txt that compiles src/main.cpp and outputs it to bin/game.exe?
18:51 rubenwardy    sorry mis-enter
18:51 MiJyn         uhhh, isn't this just the default cmakelists.txt
18:51 rubenwardy    no, for enougher project
18:51 rubenwardy    another
18:52 MiJyn         (btw, I think this should be posted on #minetest-delta)
18:52 rubenwardy    ok...
20:38 hmmmm         ugh
20:39 hmmmm         partial blocks would be tough to implement too, since you need to take direction into account for everything
20:41 hmmmm         if he wants to do this, seriously, just freaking fork minetest.. you're basically changing the game
20:42 hmmmm         as for the minetest.after thing, i'll merge that later, i still need to do some stuff such as pass out on the couch and eat dinner
20:46 Jordach       hmmmm, tell that to Taoki
20:47 Taoki         hmmmm: I don't think this would break the purpose of minetest. Slabs are basically half-voxels. It is true direction would need to be changed to do it fully, but IMO it's only needed for the ground
20:47 Taoki         Either way it can be done as an optional mod. I don't think we should be afraid to add things MineCraft never had however
20:49 RealBadAngel  hi all
20:50 hmmmm         oh taoki you're mirceakitsune?
20:50 Taoki         yep
20:50 Taoki         RealBadAngel: Hi
20:50 hmmmm         just curious, what email did you want on the credits page?
20:51 hmmmm         i used your yahoo account but
20:51 hmmmm         maybe there's something else that you'd want to be seen
20:51 RealBadAngel  tryin to compile luajit together with minetest now
20:52 Taoki         I guess any is ok. I think I'd prefer mirceakitsune@gmail.com though
20:54 RealBadAngel  shit, no luck at all
20:54 RealBadAngel  im not familiar with it
21:35 sapier1       https://github.com/minetest/minetest/pull/495 next try, I disabled metatable and raw access too
21:40 sapier1       And something completely different: https://github.com/minetest/minetest/pull/548
21:41 PilzAdam      why do you change -O1 to -O0?
21:42 sapier1       oops I'll remove it ... -O1 is not debug friendly in my opinion but celeron wants it that way
21:43 RealBadAngel  somebody here knows how to compile luajit together with minetest?
21:43 sapier1       currently this code might run on linux only (not because of features but because of timing calcultation) does anyone know how to get ns timings on windows?
21:43 sapier1       no but I assume luajit doesn't help that much
21:43 RealBadAngel  ?
21:44 RealBadAngel  its more as twice as fast comparing to lua
21:44 sapier1       no it may even be slower
21:44 RealBadAngel  wanna bet?
21:44 RealBadAngel  i do have luajit workin here
21:44 sapier1       I've even precompiled mobf
21:45 sapier1       it even slowed down mobf
21:45 RealBadAngel  technic search algorithms works more twice as fast
21:45 RealBadAngel  all is faster
21:45 sapier1       maybe that's a usecase where precombiling helps but this isn't true for everything
21:45 RealBadAngel  join vanessae server, its workin on jit
21:46 sapier1       I believe it may help for some cases
21:46 RealBadAngel  overall game performance is better
21:47 sapier1       that's not true in general
21:47 RealBadAngel  idk what tests have you done to be slower :)
21:47 RealBadAngel  it is
21:47 RealBadAngel  i can see and measure it
21:47 sapier1       its true for some(many) cases but not ALL
21:47 sapier1       ok then plz remove all mods add mobf and measure again if this is true for mobf too I don't think so
21:47 RealBadAngel  http://pastebin.com/B16s5um7
21:48 sapier1       as precompiled code should be even better
21:48 RealBadAngel  its bfs repeated 100 times (technic batbox with 100 wire nodes)
21:49 sapier1       good god ... you take the worst thing to do in lua  find out that in this scenario jit helps and guess it's helping for everything?
21:49 RealBadAngel  worst scenario?
21:49 RealBadAngel  i can see 60fps again
21:49 sapier1       search algorithms in lua ;-)
21:49 sapier1       is worst thing you can do
21:49 RealBadAngel  because game is faster, mapgen stuff
21:50 sapier1       what about debugging jitted code?
21:50 sapier1       does it work?
21:51 RealBadAngel  idk, im just testing it
21:51 RealBadAngel  game works as usual but faster
21:51 sapier        :-) I'd be glad if you succeed
21:52 sapier        but searching in lua isn't worth any optimization
21:52 sapier        you discovered yourself with treegen
21:52 sapier        I just noticed same for pathfinding ... 30s lua 100 ms c++
21:53 RealBadAngel  but moving everythin to engine is also not an option
21:53 sapier        true but maybe some generic search algorithms what exactly istechnic searching?
21:54 RealBadAngel  its bfs with some additions
21:54 sapier        bfs?
21:54 RealBadAngel  http://en.wikipedia.org/wiki/Breadth-first_search
21:55 RealBadAngel  im using 2 variants of this, 2nd with remembering parent vertice
21:56 sapier        seams to be a simple binary search
21:56 RealBadAngel  yes
21:57 sapier        what exactly is technic doing with this?
21:57 RealBadAngel  wireing
21:58 RealBadAngel  2nd is used to map connected tubes and get path for items travelling in them
21:58 sapier        hmm what do you think about adding trees to api?
21:59 sapier        nodes and linkage within core datastructures and each node has a configurable pointer to a lua object
22:00 RealBadAngel  i want to add such things to core anyway
22:00 sapier        if you do it plz do it in a very generic way
22:01 sapier        so arbitrary search algorithms could be implemented on top of it
22:01 RealBadAngel  but still, simply replacing lualib.a with libluajit.a and getting code working twice as fast...
22:01 sapier        is only usefull if it doesn't make debugging impossible
22:02 RealBadAngel  what kind of debugging?
22:02 RealBadAngel  game works as usual
22:03 sapier        debugging as of get usefull crash information if a mod crashes on a server running luajit
22:03 RealBadAngel  it crashes usual way
22:03 RealBadAngel  with all the reports
22:03 sapier        ok that's been what I was wondering ;-)
22:03 RealBadAngel  just try it for yourself
22:04 sapier        how difficult is it to get luajit running?
22:04 RealBadAngel  grab the sources, compile, take .a, rename it to liblua.a
22:04 RealBadAngel  overwrite it on already compiled minetest sources
22:04 sapier        I'll wait until you get it included ;-)
22:04 RealBadAngel  erase executables
22:05 RealBadAngel  and make again to force link with replaced lua lib
22:05 RealBadAngel  takes 2 minutes to do that
22:05 RealBadAngel  and you can switch to jit and back in no time
22:06 sapier        last time I tried to do it that easy I gave up after a day ;-) maybe I downloaded wrong luajit version or whatever
22:06 RealBadAngel  http://luajit.org/download/LuaJIT-2.0.1.tar.gz
22:06 RealBadAngel  open, go to /src and make
22:07 RealBadAngel  you will get libluajit.a
22:07 RealBadAngel  rename it to liblua.a
22:08 RealBadAngel  and overwrite the one in minetest /src/lua/build
22:11 RealBadAngel  game is workin smoother, way faster with my usual set of mods. plantlife, moretrees, technic, mesecons, moreores etc
22:12 RealBadAngel  i dont have lags on startup anymore (like a few fps freeze for half a minute)
22:13 sapier        hmm sounds great
22:13 RealBadAngel  VanessaE server is workin on jit for several hours already
22:13 sapier        almost to great to be true ;-)
22:14 RealBadAngel  just test it out
22:14 sapier        I don't have time for comprehensive testing but I'll try
22:15 RealBadAngel  ah, one more thing
22:15 RealBadAngel  builtin/serialize.lua line#200 invalid escape chars have to be removed /[ and /]
22:16 RealBadAngel  luajit doesnt allow them
22:17 RealBadAngel  otherwise you will see debug in action ;) lol
22:17 sapier        hmmm
22:17 sapier        hopfully this won't make integration of security addons even more difficult
22:18 RealBadAngel  luajit is workin as generic lua but faster
22:18 RealBadAngel  those you were afraid of were precompiled binaries
22:19 sapier        you just told an exapmle where it doesn't work as generic lua
22:19 sapier        yes precompiled binarys are a big problem too
22:20 RealBadAngel  also luajit comes with bitwise library
22:21 sapier        still I'm close to giving up adding security as there is next to noone supporting it
22:22 RealBadAngel  some1 will in the future
22:22 sapier        yes once something very bad happened
22:22 RealBadAngel  i made backgrounds for formspec and first mods using this popped up half a year later ;)
22:23 RealBadAngel  now even minetest-game uses them lol
22:23 sapier        but it was added ;-P and formspecs got only really usefull after they could be shown by lua function call ;-)
22:24 RealBadAngel  yeah
22:24 RealBadAngel  stargates are using that too
22:25 jin_xi        RealBadAngel: multimaterial turtle stuff: http://i.imgur.com/LbcIJj6.png
22:26 RealBadAngel  saw the picture already, looks great :)
22:26 sapier        what exactly do did you mean with the escape sequences?
22:26 RealBadAngel  hold on
22:27 RealBadAngel  unittest_input = {escapechars="\n\r\t\v\\\"\'", noneuropean="θשׁ٩∂"}
22:27 jin_xi        i'm now using lua to generate turtle programs. its nice being lua and all, but i dont know how to randomize stuff this way
22:27 sapier        and how to fix it?
22:27 RealBadAngel  libjua is just more strict
22:27 RealBadAngel  its not a bug
22:28 sapier        how to fix it?
22:28 jin_xi        can lua stuff run when map is generated?
22:28 RealBadAngel  what for do you need such escape chars?
22:28 sapier        on_generated
22:29 * jin_xi      checks
22:29 RealBadAngel  if you want them use % instead of /
22:29 RealBadAngel  i mean \
22:29 sapier        for formspecs maybe?
22:30 RealBadAngel  so use %
22:32 RealBadAngel  %93 will give you [
22:32 RealBadAngel  lua was just ignoring \
22:32 RealBadAngel  luajit says it is invalid escapechar
22:33 sapier        if it didn't work before it's no problem but I'm not sure about that
22:33 RealBadAngel  i dont think its a problem at all
22:34 sapier        anything that did work before and is not working now is a problem ;-)
22:34 RealBadAngel  only thing not workin is just this test line
22:34 RealBadAngel  copied and brougth to minetest from some strange place
22:35 RealBadAngel  it is not minetest code at all
22:35 RealBadAngel  and even not a part of the original serialize.lua file
22:35 sapier        as I said if it didn't work before either it's no problem ;-)
22:36 RealBadAngel  some1 merged to minetest modified version of it
22:36 RealBadAngel  which can be also found on net
22:36 RealBadAngel  googled for this today
22:39 RealBadAngel  anyway, im not familiar with cmake files
22:39 RealBadAngel  some1 will have to do that
22:41 sapier        ok seams to work at least it didn't crash on trying
22:42 RealBadAngel  i havent noticed any crash related to change yet
22:45 RealBadAngel  now you can test it
22:46 sapier        currently i wonder why i don't have minetest.settings_save ... hmm
22:47 RealBadAngel  i got an idea
22:47 RealBadAngel  lemme try it :)
22:47 sapier        thought this was merged some time ago but can't find it anymore
22:58 sapier        ahhh found the function
23:04 RealBadAngel  better test luajit ;)
23:05 sapier        I don't have any performance problems I fixed it by doing things a more smart way ;-)
23:07 RealBadAngel  for lower end machines such performance gain is huuuge
23:08 RealBadAngel  im testing now more generic stuff
23:08 RealBadAngel  wonder bout the results
23:17 hmmmm         ugh again for the 1000th time, it's definitely worth adding in luajit, it really does help, people should be able to actually do things in lua without a helper API in the core
23:17 hmmmm         besides, let's suppose it didn't help for most things:  still, why would you not use luajit?
23:18 sapier        can someone plz start a consistent project development guidline? about 6 months ago when I suggested adding luajit the suggestion was taken down by everyone
23:18 sapier        still if it helps and doesn't break anythin I support adding it
23:20 RealBadAngel  with generic stuff luajit and lua are equal
23:20 sapier        this is a limitation again is it equal or not
23:21 sapier        wait lets be precise ... do you know of any limitations?
23:21 RealBadAngel  http://pastebin.com/6zzUCwas
23:21 RealBadAngel  timings and testcode
23:22 sapier        ok you're talking about performance atm
23:22 jin_xi
23:22 jin_xi        .
23:23 jin_xi        oops
23:23 hmmmm
23:23 hmmmm         ,
23:23 RealBadAngel  with lotsa operation on tables it is definitely faster
23:23 sapier        ;
23:23 hmmmm         sapier, you mean like what i'm doing?
23:23 hmmmm         :3
23:24 jin_xi        its my cat rubbing her head at the side of the keyboard with numberblock
23:24 sapier        not exactly I want to know where minetest is heading to ... 1.5 years ago everything needed to be moved to lua
23:24 hmmmm         6 months ago somebody else was in charge and they apparently liked Lua to be weak
23:24 sapier        0.5 years ago everyone started adding everything to core
23:24 sapier        and now it seems to move back to lua again
23:24 hmmmm         well
23:24 sapier        at least thats my ipression
23:24 RealBadAngel  not really
23:25 RealBadAngel  some thing definitely have to be made in core
23:25 RealBadAngel  like common algorithms
23:25 hmmmm         don't want to move 'everything' to lua like people wanted, things that are necessary are still made in the core, but we want people to be able to actually use lua without having to add things to the core
23:25 hmmmm         because otherwise you'd just have to add a new feature to the core every time you want to do something interesting with a mod
23:26 RealBadAngel  find node near is example of core thingy
23:26 hmmmm         at which point you'd be wondering why you don't just have the whole thing in the core
23:26 RealBadAngel  find all connected nodes can be another
23:26 sapier        I think I may have a very good testcase for lua <-> luajit <-> core dijkstra pathfinding is a very heavy operation containing lua<->c interaction as well as array operations
23:26 sapier        and I have same code in lua and c++ almost ready
23:26 sapier        I'll do some tests
23:27 RealBadAngel  i do have trees in lua and core
23:27 RealBadAngel  theres nothing to compare
23:27 hmmmm         the pathfinding algorithm is a good candidate for the core, but not *everything* needs to be in the core
23:27 RealBadAngel  blink or 30s
23:27 sapier        pathfinding can only be done in core at all ... first measurements gave 10s for small paths in lua
23:27 sapier        in core it's < 10ms
23:28 RealBadAngel  finite water was another example
23:29 RealBadAngel  now lets wait for some1 makin shaders in lua ;)
23:30 hmmmm         pffff speaking of shading
23:31 hmmmm         i think i'm dumping the pseudo-ray-tracing algorithm for lighting calculations i made
23:31 sapier        btw as there are lots of core developers in here, what do you think about the idea making lua thread safe?
23:31 hmmmm         it's tough
23:31 hmmmm         you need to fix a lot of other things first
23:32 sapier        yes it can't be done at once but it's not as big as you may think
23:32 RealBadAngel  http://www.youtube.com/watch?v=uDiJyRTPF7g
23:32 RealBadAngel  make something like this
23:32 hmmmm         you need to be envlocked and conlocked while doing lua anything, so we'd be well into one of the main TODOs
23:32 sapier        no you don't
23:33 hmmmm         to call any of the lua apis you do
23:33 sapier        fore some operations you need env for others con lock
23:33 hmmmm         yeah but you don't know which ones need con and env
23:33 sapier        and of course there may not be multiple threads working on lua stack same time
23:34 hmmmm         if you're considering locking what's needed in every single api.... just try it and see how well that works
23:34 sapier        yes but you may not need to know callbacks are done using scriptapi* functions
23:34 sapier        those calling this already have lock (at least those examples I looked at)
23:35 sapier        hmm locking what is needed only is the only way to gain reall performance benefit of multicore architectures
23:35 hmmmm         well, try it :)
23:36 hmmmm         if it works out, that's awesome and we win
23:36 hmmmm         i'm just saying it's going to be a lot tougher than you think
23:36 sapier        It's not a task to be done at once
23:36 sapier        my suggestion is as started in the pull request separating lua from core more than it is atm
23:37 RealBadAngel  if everything would be easy, it wont bring any satisfaction when done
23:37 sapier        so those places where someone requires lua stack the stack will be locked
23:37 sapier        and freed as soon as possible
23:38 RealBadAngel  hmmmm, and what do you think about luajit stuff?
23:38 sapier        this will help e.g. jeijas download modification too as he doesn't need to busy wait or lock stack forever
23:39 hmmmm         realbadangel, what do you think?  i wrote "we should use luajit" in the todo list
23:39 hmmmm         lol
23:40 RealBadAngel  so it works
23:40 RealBadAngel  whos able to change cmake files then? :)
23:40 sapier        I assume noone did find anything bad by now
23:40 sapier        It's always the one asking ;-)
23:41 RealBadAngel  idk nothin bout cmake and compiling for different env
23:42 sapier        I only can add or remove files ;-) not enough for completely adding cmake support
23:43 RealBadAngel  i found luajit distro with cmake files, but it started to make unecesary objects in /bin like minilua etc
23:44 RealBadAngel  https://github.com/LuaDist/luajit
23:52 RealBadAngel  thexyz, will you be able to do that?
23:54 RealBadAngel  VanessaE's server already runnin jit for 7hrs28min ;)
23:55 sapier        by the way does anyone have an idea what to do with a pathfinding algorithm?
23:55 hmmmm         what to do with it??
23:55 hmmmm         what do you mean
23:56 RealBadAngel  write?
23:56 sapier        I've written it because I thought I could do something with it but now I see I have not even a real testcase
23:57 RealBadAngel  beacause of jit?
23:57 hmmmm         what?  of course, there are mobs
23:57 sapier        no completely unrelated ... just to get a list of points representing waypoints between two positions isn't quite a usefull feature
23:57 hmmmm         mobs?
23:57 sapier        normal mobs don't need pathfinding
23:58 sapier        maybe guard mobs could use it but even here it's not really important
23:58 RealBadAngel  items in tubes need
23:58 hmmmm         shrug
23:58 RealBadAngel  electricity, mesecons
23:58 sapier        pathfinding does only work on loaded blocks that's quite a limitation
23:58 sapier        doesn't work
23:58 sapier        pathfinding finds ways in world not in graphs
23:59 RealBadAngel  ofc it works only on loaded ones
23:59 RealBadAngel  way is a graph
23:59 sapier        not exactly
23:59 sapier        world is a special case
