| 15:36 |
red-F00 |
thats some bad luck |
| 15:39 |
pgimeno |
red-F00: yeah, that's detected by https://github.com/minetest/minetest/blob/master/cmake/Modules/FindLuaJIT.cmake as an external dependency |
| 15:40 |
pgimeno |
maybe you meant "include" as in "#include" and not as in "package" |
| 15:41 |
red-F00 |
how about we refer to #include as "included", and having it in our code tree as "bundled" from now on to avoid confusion? |
| 15:41 |
pgimeno |
yes, sorry |
| 15:42 |
red-F00 |
so yes we don't bundle it but I don't see why you can't include the header as long as everything is inside the right preprocessor cases |
| 15:43 |
pgimeno |
I meant it's not bundled. Anyway, adding cdata support requires LuaJIT internal includes that are, to my knowledge, not bundled with normal LuaJIT headers. |
| 15:44 |
pgimeno |
That's why caused my confusion, because unless LuaJIT is bundled, those headers are not available. |
| 15:46 |
pgimeno |
see e.g. https://gist.github.com/rtsisyk/6110709 |
| 15:49 |
pgimeno |
or https://github.com/AltraMayor/gatekeeper/blob/master/lib/luajit-ffi-cdata.c |
| 15:50 |
pgimeno |
(the latter is based on the above, but the includes point to ../dependencies/luajit-2.0/src/lj_* which should make it clearer that they are internal LJ headers) |

hello, can I use GMP in lua mod ? |
| 16:44 |
Krock |
only if there are extern C functions you can call with FFI |
| 16:44 |
|
AndDT joined #minetest |
| 16:45 |
quater |
minetest need GMP to compile, is it available for mod ? |
| 16:47 |
pgimeno |
not directly; if you've compiled your minetest with LuaJIT enabled, then what Krock said |
| 16:49 |
quater |
without LuaJIT, can I access it ? |
| 16:50 |
Krock |
minetest.check_password_entry and minetest.get_password_hash can be accessed from the Lua API. Always. |
| 16:50 |
Krock |
These use some GMP functions, if you meant that |
| 16:50 |
Krock |
if you want anything else, it can't be done without FFI |
| 16:50 |
Krock |
or an engine change, of course |
| 16:53 |
quater |
something like: local ffi = require("ffi") |
| 16:54 |
Krock |
something like that. if there was no mod security |
| 16:54 |
Krock |
with mod security, you'll either have to disable that or add the mod to your trusted_mods setting |
| 16:55 |
Krock |
then request the insecure env like this: local ie = minetest.request_insecure_environment() local ffi = ie.require("fii") |
| 16:57 |
quater |
ok |
| 16:58 |
Krock |
however, after scrolling through the bundled mini-gmp.c I think there's no function you could call from Lua, even with FFI, as they're not marked as extern ones |
| 16:59 |
pgimeno |
are they marked as static? if not, I don't see why they can't be called with FFI |
| 17:01 |
pgimeno |
using C functions through FFI is not that easy though; you need to basically replicate the C header in the Lua side, sometimes with a few changes |
| 17:03 |

| 17:09 |
red-F00 |
what for? |
| 17:09 |
red-F00 |
pgimeno, can you call c++ functions if you handle the name mangling yourself? |
| 17:11 |
pgimeno |
ah sorry, not marked extern "C" |
| 17:11 |
pgimeno |
red-F00: yes, if you know the compiler and platform used |
| 17:12 |
red-F00 |
but I assume they also have to be extern right? |
| 17:12 |
red-F00 |
unless this does some next level magic |
| 17:13 |
pgimeno |
at this point I'm not sure, I assumed that the executable had the symbols not marked as static (unless stripped) |
| 17:13 |

pgimeno, can ffi set variable values> |
| 17:13 |
red-F00 |
*? |
| 17:14 |
pgimeno |
red-F00: not sure, I haven't tried to do that |
| 17:15 |
pgimeno |
if you can get a pointer to a variable, certainly |
| 17:17 |
pgimeno |
e.g. int var; int *var_ptr() { return &var; } then in the LuaJIT side: ffi.cdef 'int *var_ptr();' local var_ptr = ffi.C.var_ptr(); var_ptr[0] = 5 |
| 17:18 |
pgimeno |
that sets var to 5 |
| 17:18 |
red-F00 |
I mean obviously it can if you know the address of the variable I was wondering if it also could get the address of extern variables by name |
| 17:20 |
pgimeno |
it seems you can, I haven't ever tried it though |
| 17:20 |
Krock |
I did some insecure stuff: https://pastebin.com/WXAydxT3 creating an uninitialized pointer array, which then gets modified by C++ to the MapNode data in the Vmanip |
| 17:20 |
pgimeno |
"ffi.cdef(def) Adds multiple C declarations for types or external symbols (named variables or functions)." |
| 17:20 |
pgimeno |
note "variables" |
| 17:22 |
pgimeno |
Krock: cool |
| 17:23 |
quater |
yes, to secure the exchanges between players |
| 17:24 |
rubenwardy |
it'd probably be easier to find a lua library for this |

pgimeno |
Krock: I'm not sure the double indirection is necessary. Can't the function just return it? |
| 17:27 |
Krock |
pgimeno, I wasn't sure whether LuaJIT/FFI would accept that as CDATA |
| 17:27 |
Krock |
or do you mean as #2 argument in ffi.new() ? |
| 17:28 |
pgimeno |
I mean in the case of MapNode **data, I think the function can return MapNode *VoxelManip_get(void **lvmp) |
| 17:28 |
* red-F00 |
waits for mapgens to be leaky |
| 17:29 |
Krock |
red-F00, that will result in amazing fast mapgens if done right |
| 17:29 |
Krock |
using a struct (as in using the entire MapNode data) seems to slow down LuaJIT quite much |
| 17:30 |
pgimeno |
maybe due to cache locality? |
| 17:30 |
pgimeno |
I don't know |
| 17:32 |
Krock |
array[index1][index2] is the same as array[index1].index2 (used in the script), which is an additional step to get the right value for each coordinate |
| 17:35 |
pgimeno |
hm, I expected that to be compiled to very plain code |
| 17:36 |

quater, I don't see the point... |

thanks, I wondered because there was already one approval |

kinda funny how LuaJIT claims it means you don't have to write bindings to use FFI |
| 18:20 |
red-F00 |
it just means it has to be reapproved by that dev |
| 18:20 |
Krock |
how's that going to work? perlin noise is ~1 ... ~(-1). FFI only makes it faster when dealing with integers |

sorry I'm just kinda annoyed since it was ~half a year since I finished that and all I did in the meantime was rebase it like once |
| 18:22 |
pgimeno |
Krock: it's not so much for accelerating it, as it is for being able to do the allocation in memory not restricted by LuaJIT's limits |
| 18:23 |
Krock |
if so, then it's an ugly fix. can't we modify a Lua variable pointer (if existent) to our fresh generated array/data? |
| 18:24 |
red-F00 |
and moved a list from one part of the code to another a few months ago |
| 18:25 |
pgimeno |
Krock: it also uses memcpy or even directly the array, hence a bit faster to access the data (not that that should make much of a difference). I'm not aware of Lua variable pointers, besides LuaJIT cdata. |

hey, asked this some days ago and got no response.. is there some way to tell minetest to crop textures instead of resizing them? i made some bigger textures intended to be placed in formspecs as a progress indicator, it looks rather ugly when the texture gets resized, the correct way would be to crop them imo, i dont see any reason why it schould resize them, ever |
| 18:41 |
rubenwardy |
I believe you may be able to do that with texture modifiers |
| 18:41 |
Krock |
like the furnace progress arrow? |
| 18:41 |
rubenwardy |
it makes sense to resize them as the element is to show an image at that position and size |
| 18:41 |
rubenwardy |
although stretching is ew |
| 18:42 |
nepugia |
well, i have no other way currently to show textures in a formspec :3 |
| 18:43 |
rubenwardy |
say you have an 64x16 image foo.png |
| 18:43 |
rubenwardy |
[combine:8x16:0,0=foo.png |
| 18:43 |

@krock a bar that increases in size from left to right (i attempted to code right to left aswell, but the width and height parameters or picture[ seem to operate with another scale compared to the x and y position) |
| 18:44 |
nepugia |
do i need to calculate the pixels for the image then? formspecs operate on inventory sizes though afaik, how would i get the correct conversion rate |
| 18:45 |
rubenwardy |
1 slot is 64 pixels on a standard screen |
| 18:45 |
rubenwardy |
a standard screen is 96 DPI at 800x600 I believe |
| 18:45 |

always? |

nepugia, https://github.com/minetest/minetest_game/blob/master/mods/default/furnace.lua#L15-L16 |

if the DPI increases, the pixel increases |
| 18:45 |
Krock |
use lowpart and then rotate |
| 18:45 |
rubenwardy |
ah there we are |
| 18:45 |
rubenwardy |
Ah! |
| 18:45 |
rubenwardy |
I saw lowpart but didn't think to rotate it |
| 18:46 |
Krock |
use it after rotating again if you want to chop it from two sides |
| 18:48 |
nepugia |
where is this documented? i dont really understand what lowerpart is supposed to do |

rubenwardy |
or https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L478 |
| 18:49 |
rubenwardy |
you want texture modifiers |
| 18:49 |
rubenwardy |
they're not specific to formspecs |
| 18:49 |
rubenwardy |
Basically, lowpart is lower part |
| 18:49 |
nepugia |
hmm, my browser sais the certificate expired 13 minutes ago :3 |
| 18:49 |
rubenwardy |
and it copies the lower % of an image to the texture |
| 18:50 |
rubenwardy |
ehat |
| 18:51 |
nepugia |
then i would have to calculate the percentage, for which i would need to know the inventory<->pixel thingy |
| 18:51 |
rubenwardy |
nepugia, looks like my auto renew failed |
| 18:51 |
rubenwardy |
doing it now |
| 18:51 |
rubenwardy |
I thought it's a progress bar? |
| 18:52 |
rubenwardy |
nepugia, done |
| 18:52 |
nepugia |
yes |
| 18:52 |
rubenwardy |
surely you'd know the progress if it's a progress bar? |
| 18:54 |
nepugia |
my texture is 1080pixels wide, my progress is 30%, now how would i calculate the percentage to cut the image if the area i need to fill is much smaller than 1080px |
| 18:54 |
nepugia |
i already know how to tell minetest where to put it, if i now cut it in the wrong place it will be stretched or squezzed |
| 18:54 |
nepugia |
and both will look shitty |
| 18:54 |
rubenwardy |
use 30% and size the image element so it's 30% of the max (in units |
| 18:54 |
nepugia |
(still, beeing able to tell it to just use the image 1:1 and crop off the rest it doesnt need would be a fairly elegant solution) |
| 18:55 |
nepugia |
again, i have no idea how many units me image is |
| 18:55 |
rubenwardy |
how big is the window? |
| 18:55 |
nepugia |
they dont appear to have a fixed conversion rate |
| 18:55 |
rubenwardy |
images resize their content |
| 18:55 |
nepugia |
how would i know? |
| 18:55 |
rubenwardy |
size[w,h] |
| 18:56 |
rubenwardy |
sorry, window as in formspec dialog |
| 18:57 |
nepugia |
having to querry information about dpi window size to calculate a conversion rate just to be able to put an image into a formspec seems rather overkill to me |
| 18:57 |
rubenwardy |
you don't |

news flash: formspecs suck ass and should be replaced with a better system at the next possible point |
| 18:57 |
rubenwardy |
that too |
| 18:57 |
nepugia |
i dont know how big the formspec window is either, i made a utility function to append the progress bars |
| 18:57 |
rubenwardy |
but you just need to decide how big the progress bar should be in formspec sizes |
| 18:58 |
rubenwardy |
so if the window is size[8;6] you may decide to make the progress bar 7,1 |
| 18:58 |
rubenwardy |
in which case the image should be of a ratio 7:1 |
| 18:58 |
rubenwardy |
then when making the formspec, make the progress bar size 7*progress,1 |
| 18:58 |
rubenwardy |
and crop using lowpart |
| 18:59 |
nepugia |
you dont understand me, the image has to be cropped |
| 18:59 |
nepugia |
it will look shtity otherwise |
| 18:59 |
rubenwardy |
I don't understand you |
| 18:59 |
rubenwardy |
what is the image? |
| 18:59 |

the way I say won't have any stretching, and will crop to the right |

sfan5 |
no that's not an option ;) |
| 19:01 |
nepugia |
@rubenwardy if i specify a percentage that is too big it will still crop the rest of the image, otherwise there is really no point in specifying a percentage |
| 19:01 |
rubenwardy |
well, cap at 100$ |
| 19:01 |
rubenwardy |
*100% |
| 19:01 |
rubenwardy |
then the entire image will be shown in the entire image element |
| 19:01 |
rubenwardy |
at 50%, the image element will be half as wide |
| 19:01 |
rubenwardy |
but the image will also be cropped to be half as wide |
| 19:01 |
nepugia |
i dont want that, i want it to fill the area 1:1 |
| 19:02 |
nepugia |
and crop the rest |
| 19:02 |

no possible |
| 19:02 |

do each step in GIMP and switch the texture each time 8) |

possible surely, with way too much coding involved (at the lua side anyway).... unless someone made an image[ alternative that cropped |

is there any way to get a callback for when a player wants to acces a blocks formspec? |
| 19:46 |

(so i can modify the formspec beforehand) |

if that formspec is contained in the metadata, no |

.-. |
| 19:48 |
rubenwardy |
you can use on_rightclick to show the formspec instead |
| 19:48 |
rubenwardy |
but there will be latency |
| 19:48 |
rubenwardy |
but for your usecase that's fine |
| 19:48 |

could i then show the formspec to the players upon them rightclicking the block? |

rubenwardy |
depends |
| 19:50 |
rubenwardy |
in most cases no |
| 19:50 |
rubenwardy |
but it does depend on the player's internet |
| 19:50 |

ah, so bugs that definetely wont show up in singleplayer testing, nice |

rubenwardy |
also, when you use Facebook to monitor certificate registrations on your site: https://i.rubenwardy.com/62ZoeHaP6m.png |
| 19:51 |
nepugia |
well, the other option i have is to continiously update the formspec in the background, which seems like a huge waste of ressources |
| 19:53 |
nepugia |
what functions would i loose if i use it in on_rightclick then? |
| 19:56 |
rubenwardy |
nepugia, nothing |
| 19:57 |
rubenwardy |
the only difference between formspecs in meta and show_formspec is the time difference (meta formspecs are shown instantly as the client has them locally) and which callbacks are ran (meta formspecs use a node definition, normal formspecs use a global callback) |
| 20:00 |
nepugia |
minetest uses a lua compiler though? if i have a specific static formspec and either store it in node meta or show it as formspec on_rightclick i wouldnt really expect any difference in time |
| 20:00 |
rubenwardy |
in singleplayer, no |
| 20:01 |
rubenwardy |
only in multiplayer / on a remote server |
| 20:01 |
rubenwardy |
as the server needs to send a message with the formspec's content |
| 20:05 |
nepugia |
hmm, is there a way to see if a player still has the formspec open (as to update the content while the player still has it open) |
| 20:06 |
|
sy joined #minetest |
| 20:07 |
rubenwardy |
there's events when they close it |
| 20:07 |
rubenwardy |
but that's subject to network latency |
| 20:07 |
rubenwardy |
ie: you may sent an update just after they closed it, but before you receive a notification that it was closed |
| 20:07 |
nepugia |
i think i can use register fields and on_rightclick for this |
| 20:07 |
nepugia |
though, it could lead to some cases where it would reopen it if it was already closed :/ |
| 20:07 |
rubenwardy |
this is where client-side scripting will be useful, when ready |

I am trying: |
| 23:16 |
quater |
local file = io.open(core.get_modpath('csm_lua') .. '/TODO') |
| 23:16 |
quater |
local text = io.read(file); |
| 23:16 |
quater |
core.display_chat_message(text) |
| 23:17 |
quater |
it is a CSM |
| 23:17 |
red-F00 |

| 23:17 |

you'll need to use mod_storage instead |
| 23:18 |
rubenwardy |
to store data on the client |

well harddrive space is cheap |
| 23:22 |
red-F00 |
so eh don't use minetest on an ssd |
| 23:23 |
red-F00 |
in all seriousness we should just let the user set a storeage size limit |
| 23:23 |
sofar |
csm storage should be per server |
| 23:23 |
sofar |
or transient |
| 23:23 |
rubenwardy |
no, timeout |
| 23:23 |
red-F00 |
you would know if you got kicked |
| 23:24 |
red-F00 |
sofar, not worth implementing that till we get around to having the server send the mods but yes it should be |
| 23:25 |
red-F00 |
also we should use a database for all modstorage |
| 23:26 |
red-F00 |
if we do make it per-server it would be nice to also give server guid's |
| 23:26 |
red-F00 |
