don't you just love it when you're exploring your own server, and you're like "wait, who's been way out here?" |

I was following an electrical feed, reworking poles, before I knew it I was 3km east of the spawn :) |

i was just exploring to look for a good spot to setup a pixel art area and i found random torches in the ocean. i'm a good kilometer and a half from spawn and it's a fairly new server |

I can't seem to get windows 10 to get past that stupid fall creators update so I don't guess it will get the update any time soon... |

I did try and look, and saw Version History shows the first release (0.2.20110529) on may 29th 2011. but by that version number I would guess it to be older |

cool. I'm guessing there's an automated tool for that? |

its over my head, he volunteered to do it...which is great |

So it appears that in lua, require() is just a more efficient version of dofile(), in that it only runs the other script once, then caches the result. But when trying to split up my code, I got require() is disabled when mod security is on. Why is it that we're forced to use the less efficient dofile()? |
| 03:31 |
erudition |
(open query for anyone that might know) |
| 03:33 |

Cornelia |
I think require looks on the path |
| 03:38 |
Cornelia |
Oh... |
| 03:38 |
Cornelia |
erudition: require can load binary code |
| 03:39 |
Cornelia |
dofile is restricted to Lua scripts |
| 03:39 |
erudition |
can't we just block that part of it? |
| 03:39 |
erudition |
I see |
| 03:39 |
Cornelia |
require doesn't execute scripts, it loads a module |
| 03:39 |
Cornelia |
And a module could even a script, but it could also be native code |
| 03:39 |
Cornelia |
So to prevent mods from doing "very bad things" they can't use require |
| 03:40 |
erudition |
even though it's only the native code that's bad |
| 03:40 |
Cornelia |
Can't really block part of built-in Lua functionality without rewriting Lua :p |
| 03:41 |
Cornelia |
It's easier to just stop the require call and only allow dofile and loadfile |
| 03:41 |
Cornelia |
If you want the "load once" behaviour: |
| 03:41 |
erudition |
seems like just checking the MIME type of called files would work |
| 03:41 |
erudition |
but I guess not |
| 03:41 |
erudition |
so how does one load a module? |
| 03:41 |
Cornelia |
local my_file = loadfile("my_file.lua") ; my_file() |
| 03:42 |
Cornelia |
I don't think we can load modules. We can run Lua scripts, though |
| 03:42 |
erudition |
:( I just want to split up my code |
| 03:42 |
Cornelia |
Put your pieces in their own files and use dofile :p |
| 03:43 |
Cornelia |
Or loadfile |
| 03:43 |
Cornelia |
I'm using dofile to load in tables that contain code I need |
| 03:43 |
Cornelia |
Like I have a "settings.lua" that reads in Minetest settings and returns a table |
| 03:43 |
Cornelia |
Well.. I will. :P |
| 03:44 |
Cornelia |
I currently just have an empty file while I'm building the mod |
| 03:44 |
erudition |
is that the same as if they were in the same file? |
| 03:46 |
Cornelia |
Sorta |
| 03:46 |
Cornelia |
You can, at the end of your extra script, return something |
| 03:46 |
Cornelia |
I.e. return { ... } |
| 03:47 |
Cornelia |
And when you do: local data = dofile("data.lua") |
| 03:47 |
Cornelia |
That table will be in the data variable |
| 03:47 |
Cornelia |
dofile executes the file as a chunk in the same space as the others.. so if you make globals they'll be visible.. |
| 03:47 |
Cornelia |
But.. they'll be visible to ALL MODS |
| 03:48 |
erudition |
well say I have a utility function, such as function say(msg) minetest.chat_send_all(msg) end |
| 03:48 |
Cornelia |
Mmkay.. |
| 03:48 |
erudition |
and I want all my utility functions in a separate file |
| 03:48 |
Cornelia |
You should be using "local function" or it's global and visible to all mods |
| 03:49 |
Cornelia |
I think... :P |
| 03:49 |
erudition |
how can I call say(stuff) from init.lua |
| 03:49 |
Cornelia |
One moment... |
| 03:49 |
erudition |
without any extra periods haha |
| 03:50 |
Cornelia |
https://github.com/CorneliaXaos/guidebooks/blob/master/api/init.lua |
| 03:51 |
Cornelia |
In progress code.. so that stuff might not be 100% correct :p |
| 03:51 |
Cornelia |
But look at "local implementation = ..." |
| 03:51 |
Cornelia |
Then look at this: |
| 03:52 |
Cornelia |
https://github.com/CorneliaXaos/guidebooks/blob/master/api/implementation.lua |
| 03:52 |
erudition |
wouldn't that mean having to call implementation.say() |
| 03:52 |
erudition |
? |
| 03:52 |
Cornelia |
Yes. |
| 03:52 |
erudition |
which defeats the purpose of shortening the name lol |
| 03:53 |
Cornelia |
But.. it lets you split your code up |
| 03:53 |
Cornelia |
Instead of having it all in one giant init.lua |
| 03:54 |
erudition |
yeah, but looks like I'll have to put my say() function at the bottom of every lua script |
| 03:54 |
erudition |
if i want to use it for its purpose |
| 03:54 |
Cornelia |
Why.... |
| 03:54 |
Cornelia |
You could put it in a "chat_functions.lua" |
| 03:54 |
erudition |
again, that defeats the purpose |
| 03:54 |
Cornelia |
And dofile it into a local chat variable |
| 03:55 |
erudition |
did you see what the function did? |
| 03:55 |
Cornelia |
Then call chat.say where needed. |
| 03:55 |
erudition |
It's just to shorten minetest.chat_send_all(msg) to a concise say() |
| 03:55 |
erudition |
since I'm using it often |
| 03:55 |
Cornelia |
Oh.. |
| 03:55 |
Cornelia |
Then.. |
| 03:56 |
Cornelia |
local say = minetest.chat_send_all |
| 03:56 |
Cornelia |
But that would have to go in every file |
| 03:56 |
erudition |
like in Java, i dont want System.out.println() |
| 03:56 |
Cornelia |
Personally, I'm against shortening the built-in functions |
| 03:56 |
erudition |
so i make a method called say() |
| 03:56 |
Cornelia |
"built-in" |
| 03:56 |
erudition |
or "print" |
| 03:56 |
Cornelia |
Ewww.. (sorry) |
| 03:56 |
Cornelia |
That just spaghettis the code |
| 03:57 |
erudition |
what? you prefer System.out.println()? |
| 03:57 |
Cornelia |
It's fine if you could potentially have different ways of saying things |
| 03:57 |
Cornelia |
I would just use the full call, yes. |
| 03:57 |
erudition |
you're the first i know of |
| 03:57 |
Cornelia |
Like sometimes say calls the Minetest function, and others it prints a log or something. |
| 03:57 |
erudition |
"print" is such a basic thing, ya know? |
| 03:57 |
Cornelia |
Lua has a print |
| 03:58 |
Cornelia |
It'll go to the log file, though. |
| 03:58 |
erudition |
right - and it's nothing but "print" |
| 03:58 |
erudition |
which is beautiful |
| 03:58 |
erudition |
that's all I want :) |
| 03:58 |
Cornelia |
Yea, Well.. Lia is a hyper-small interpreted language. |
| 03:58 |
Cornelia |
Java has a massive standard library |
| 03:58 |
Cornelia |
*lua |
| 03:58 |
erudition |
javascript then |
| 03:59 |
erudition |
BASIC |
| 03:59 |
Cornelia |
Again.. |
| 03:59 |
Cornelia |
Probably writes to the log |
| 03:59 |
Cornelia |
Or the console |
| 03:59 |
Cornelia |
Saying something to players isn't "basic" |
| 03:59 |
erudition |
when it comes to this domain... |
| 03:59 |
Cornelia |
It has to do a bunch of networking to get it across |
| 04:00 |
erudition |
it's *the* most basic |
| 04:00 |
erudition |
sure, but that's not exposed to us |
| 04:00 |
Cornelia |
And to organize namespaces appropriately, Minetest functions are put into a Minetest global table |
| 04:00 |
erudition |
"print" isn't basic either then haha |
| 04:01 |
Cornelia |
Well.. why don't you do this: |
| 04:01 |
erudition |
yeah, that's fine |
| 04:01 |
Cornelia |
local print = minetest.chat_send_all |
| 04:01 |
erudition |
maybe I could do say = otherfile.say |
| 04:01 |
erudition |
ah |
| 04:01 |
erudition |
same thing |
| 04:01 |
Cornelia |
You could even... |
| 04:01 |
erudition |
since functions are first class values |
| 04:02 |
Cornelia |
--[[ start of mod init.lua ]] say = minetest.chat_send_all ; ... bunch of Lua code and calls to dofile ... ; say = nil -- end of init.lua |
| 04:03 |
Cornelia |
Since say is global, dofile will see it |
| 04:03 |
Cornelia |
Even safer is to add a "local old_say = say" and set say to old_say at the end |
| 04:03 |
erudition |
that's perfect |
| 04:04 |
Cornelia |
As long as you didn't call any mod which needed old_say you'd be fine |
| 04:04 |
erudition |
although what's unsafe about say()? |
| 04:04 |
Cornelia |
But I find that to be a hack. |
| 04:04 |
erudition |
it's just an alias for a command that every other mod can use anyway |
| 04:04 |
erudition |
why set it to nil? |
| 04:04 |
Cornelia |
1) pollutes globals table, 2) what if there's a mod called "say" |
| 04:04 |
Cornelia |
Setting to nil clears the value |
| 04:04 |
Cornelia |
Do the old_say isntead |
| 04:05 |
Cornelia |
*instead |
| 04:05 |
erudition |
well it doesn't pollute anything if it's local |
| 04:05 |
erudition |
oh, then dofile can't see it, hmm |
| 04:05 |
Cornelia |
local old_say = say ; say = minetest.chat_send_all ; ... ; say = old_say |
| 04:05 |
Cornelia |
The point -- yea |
| 04:06 |
erudition |
haha set the other mod to old_say |
| 04:06 |
erudition |
nice |
| 04:06 |
Cornelia |
Making it global makes it so you wouldn't have to redefine it in every chunk. |
| 04:06 |
Cornelia |
Hmm.. |
| 04:06 |
erudition |
would that really be a conflict with a mod? isn't a mod more than just a function |
| 04:06 |
Cornelia |
I wonder if it's still work with local say (the dofile's I mean) |
| 04:07 |
erudition |
i.e., a mod called "say" doesn't mean that say() is a thing, does it? |
| 04:07 |
Cornelia |
The PIL book says dofile compiles the script file as a chunk and executes it in the current context... I think.. |
| 04:07 |
Cornelia |
Most mods make a global table that is called the mod's name |
| 04:08 |
Cornelia |
It might not, but it could. |
| 04:08 |
erudition |
damn |
| 04:08 |
erudition |
who knew it was so complicated just to make an alias |
| 04:09 |
erudition |
alright, so dofile isn't working anyway xD |
| 04:09 |
Cornelia |
Of you have access to a Lua interpreter test things: |
| 04:09 |
erudition |
yeah i can try accessing it from a dofile |
| 04:09 |
Cornelia |
--[[ inside test.lua ]] local say = print ; dofile("other.lua") |
| 04:10 |
Cornelia |
--[[ inside other.lua ]] say("something") |
| 04:10 |
Cornelia |
It either works or you get an error. |
| 04:10 |
Cornelia |
> lua test.lua |
| 04:10 |
Cornelia |
See what happens. |
| 04:10 |
Cornelia |
I'm on my phone and can't. :P |

no I'm full time gnu/linux |

I guess I will later when I can get the files over here |

erudition |
Lord_Buckethead: yeah... |
| 04:16 |
Lord_Buckethead |
with dofile, loadfile, etc there are APIs you can reuse |
| 04:16 |
erudition |
Cornelia: yep, i know |
| 04:16 |
Lord_Buckethead |
require is kinda a blackbox, or at least it seems so |
| 04:17 |
Cornelia |
I would have tested it already.. but my Android phone doesn't have a Lua interpreter. :P |
| 04:17 |
Lord_Buckethead |
Cornelia, https://www.lua.org/demo.html |
| 04:17 |
erudition |
actually the shell doesn't like the quotes |
| 04:17 |
Lord_Buckethead |
bookmark that |
| 04:17 |
Cornelia |
We need files. |
| 04:17 |
erudition |
^this |
| 04:17 |
Cornelia |
We're testing dofile |
| 04:18 |
Cornelia |
Replace them with single quotes |
| 04:18 |
Lord_Buckethead |
what do you want to (ab)use it to do? |
| 04:18 |
erudition |
seeing if dofile can see locals |
| 04:18 |
Cornelia |
It should be fine then... Or.. just vim the files first |
| 04:19 |
Lord_Buckethead |
iirc no because it changes the scope |
| 04:19 |
erudition |
not in fish |
| 04:19 |
erudition |
but yeah I got it |
| 04:19 |
Cornelia |
From what I recall when I read the PIL book.. dofile (or at least loadfile) make the script it loads / does a function and executes it as a single chunk.. I was wondering if it saw the locals declared before the dofile |
| 04:20 |
Cornelia |
You could also try loadfile("other.lua")() |
| 04:20 |
Cornelia |
:p |
| 04:20 |
Lord_Buckethead |
Cornelia, https://www.lua.org/pil/4.2.html |
| 04:20 |
Lord_Buckethead |
its limited by chunk |
| 04:20 |
Cornelia |
Ah.. I see. |
| 04:20 |
Cornelia |
Yea.. |
| 04:21 |
Lord_Buckethead |
and any script loading/execution function **has** to change chunk |
| 04:21 |
Cornelia |
I was remembering wrong. :P |
| 04:21 |
Cornelia |
So.. yea.. If you really want a global "say" you could try the temporary redefinition approach, erudition |
| 04:22 |
erudition |
mhm |
| 04:22 |
Cornelia |
But I'd recommend just returning a table with the function from a "utility.lua" file |
| 04:22 |
Cornelia |
local utils = dofile("utils.lua") |
| 04:22 |
erudition |
alright |
| 04:22 |
Cornelia |
utils.say |
| 04:22 |
erudition |
mhm. assuming dofile works |
| 04:22 |
Cornelia |
It's cleaner and less likely to break something. |
| 04:23 |
erudition |
yup |
| 04:25 |
erudition |
local tools = dofile("tools") |
| 04:26 |
erudition |
or does the path have to be minetest.get_modpath("mymod") .. "\tools.lua" |
| 04:26 |

You need the mymodpath .. |

it's there |
| 04:28 |
erudition |
maybe the odd forward slash ? |
| 04:28 |

| 04:28 |
Cornelia |
Shouldn't matter |
| 04:28 |
Lord_Buckethead |
shouldn't |
| 04:28 |
erudition |
that's what i thought |
| 04:28 |
Lord_Buckethead |
are you sure the file exists? |
| 04:29 |
Lord_Buckethead |
maybe you named it tool.lua or something |
| 04:29 |
erudition |
tools.lua haha |
| 04:30 |
Cornelia |
Is your mod called "Master"? |
| 04:30 |
erudition |
nope, that's the master branch, we have it in git |
| 04:30 |
Cornelia |
Is "viralblocks" a mod in a mod pack called "Master"? |
| 04:31 |
Cornelia |
Yea.. that might be why things are funky.. |
| 04:31 |
erudition |
technically, yes |
| 04:31 |
erudition |
i added a modpack.txt |
| 04:31 |
Cornelia |
Hmm.. |
| 04:32 |
Cornelia |
Is this on GitHub? |
| 04:33 |
erudition |
yes actually |
| 04:34 |
Cornelia |
Can I see the URL? :P I just wanna peek and see if I can spot an error or not. |

absolutely. thanks for your help and patience |

You.. declare a lot of globals right away.. |

WIs joined #minetest |
| 04:39 |
Cornelia |
Also the functions you declare in tools.lua are global |
| 04:40 |
erudition |
well at the time we wanted it to be library-ish |
| 04:40 |
erudition |
but i'll have to fix that too |
| 04:40 |
Cornelia |
First question: does the paths in the errors above exist? |
| 04:41 |
Cornelia |
The closest way to "library-ish" is to make the file return a table containing the functions. |
| 04:41 |
erudition |
gotcha - still trying to get used to the whole tables thing |
| 04:42 |
erudition |
the paths in the error were straight from the generated minetest.get_modpath("mymod") .. "\tools.lua" |
| 04:43 |
Cornelia |
Yes.. but do they exist on your system? :P |
| 04:43 |
Cornelia |
It looks like they should. |
| 04:45 |
erudition |
do they @WIs? |
| 04:45 |
erudition |
it's his windows system lol |
| 04:45 |
Cornelia |
Was that using require? |
| 04:45 |
Cornelia |
Probably not, right? |
| 04:46 |
Cornelia |
Hmm.. |
| 04:46 |
erudition |
no, require gave security error |
| 04:46 |
Cornelia |
I don't think I'll be able to help much more... If my computer were on I could test it. |
| 04:46 |
erudition |
okay, thanks though |
| 04:47 |
Cornelia |
I'm not sure why that isn't working.. |
| 04:47 |
Cornelia |
I've seen several mods do similar. |
| 04:48 |
Cornelia |
Take a peek here: https://github.com/minetest-mods/technic/blob/master/technic/init.lua |
| 04:48 |
erudition |
does minetest cache the mods directory? |
| 04:49 |
Cornelia |
I wouldn't think so. :P |
| 04:49 |
erudition |
so i don't need to restart it to see a new file |
| 04:49 |
erudition |
okay |
| 04:50 |
Cornelia |
Oh.. hmm.. |
| 04:50 |
Cornelia |
I think you'd just need to reload the world. |
| 04:51 |
Cornelia |
But I'm not certain. :P |
| 04:52 |
erudition |
okay, got it to work on my system, sweet |
| 04:53 |
erudition |
so will local say = tools.say work? |
| 04:53 |
erudition |
just curious |
| 04:54 |
Lord_Buckethead |
yes |
| 04:54 |
erudition |
great |
| 04:55 |
Lord_Buckethead |
you can even get a local right that and then replace the value of tools.say |
| 04:55 |
erudition |
a local right that? |
| 04:56 |
Lord_Buckethead |
like that |

probably not the best first mod haha |
| 05:00 |
erudition |
or first-time-with-lua thing |
| 05:00 |
Lord_Buckethead |
huh what are the rules like for 3d versions of that? |
| 05:00 |
Lord_Buckethead |
s/3d/interesting 3d/g |
| 05:00 |
erudition |
those exist! and there's at least one mod for that |
| 05:01 |
erudition |
but actually I'm just interested in 2d planes |
| 05:01 |
erudition |
so every height could theoretically be a separate playing board |
| 05:01 |
* Lord_Buckethead |
briefly wonders did anyone figure out how to get it to work in n-dimensions |
| 05:02 |
erudition |
that's pretty trivial actually, but you'd need to make up rules for every dimension |
| 05:04 |
|

a 72-sided cell survives if it has how many neighbors? 37-46? haha |
| 05:04 |
Lord_Buckethead |
that kinda feels like cheating, I was thinking of a set of rules that works in a whole bunch of dimensions |
| 05:05 |
erudition |
but you couldn't visualize that anyway, which is the fun part :P |
| 05:05 |
erudition |
oh sure, the rules could be like dimensions/3 or something |
| 05:05 |
Lord_Buckethead |
like die if neightbour =< floor(N * 1.5) |

it's been interesting |

Lord_Buckethead |
ABMs are horrible |
| 05:08 |
erudition |
so we've learned |
| 05:08 |
Lord_Buckethead |
don't see why it wouldn't work |
| 05:08 |
erudition |
why what wouldn't? |
| 05:08 |
Lord_Buckethead |
'air' isn't really all that diffirent from 'default:stone' |
| 05:09 |
erudition |
oh I know |
| 05:09 |
Lord_Buckethead |
erudition, abms for air nodes |
| 05:09 |
erudition |
I'm sure I could assign an abm to every air node somehow |
| 05:09 |
erudition |
but that would blow up |
| 05:10 |
Lord_Buckethead |
so assign ABMs to your game of life nodes |
| 05:10 |
erudition |
we did lol |
| 05:10 |
erudition |
that's no enough |
| 05:11 |
erudition |
two problems with that - one is that it's only good for the die/survive rules |
| 05:11 |
erudition |
another is abms occur in an erratic order |
| 05:11 |
Lord_Buckethead |
they were never meant for this |
| 05:11 |
erudition |
you don't say haha |
| 05:11 |

...how do I put this... |

| 16:02 |
t20kdc |
I'm just going to quickly test some 32-bit floating point maths. |
| 16:02 |
t20kdc |
Should give you an idea of what happens when the limits are exceeded. |
| 16:03 |
Billre |
I wouldn't even know where to begin testing that limit |
| 16:04 |
t20kdc |
"62823.000000 + 12.340000 = 62835.339844" |
| 16:06 |
t20kdc |
Notice that at this point (double the safety margin) the margin of error is already over 0.00015 - when working with entities that have velocities multiplied by delta-time under a certain value, that's not good. |
| 16:07 |
t20kdc |
Something going at 1 block per second at 100FPS is going at 0.01 - at that point calculation errors can have a visible effect over time. |
| 16:08 |
t20kdc |
*at 0.01 per frame - |
| 16:08 |
t20kdc |
I'm also not sure what the details regarding mapblock IDs are, so it's possible they could have an inherent limit. |

Hey erudition |
| 21:01 |
pgimeno |
rubenwardy: I have the modification to #6896 (the off-by-one in logging) ready. What's customary in these kind of cases? To get rid of the previous patch and force-push the new? Or to add to the PR? |
| 21:01 |
erudition |
Cornelia: hiya |
| 21:02 |
rubenwardy |
errr, new commit I guess |
| 21:02 |
rubenwardy |
incase someone takes offense |
| 21:02 |
rubenwardy |
we'd just squash it on merge anyway |
| 21:02 |
pgimeno |
okay, thanks |
| 21:02 |
pgimeno |
I'm not fan of squashes, but I agree they're necessary sometimes |
| 21:03 |
rubenwardy |
it keeps the commit history clean, although you should only squash if it's fixing a mistake in a commit |
| 21:03 |
rubenwardy |
and in a feature branch |
| 21:03 |
pgimeno |
kk |
| 21:03 |
rubenwardy |
this was merged unsquashed as there's separate steps to it: https://github.com/minetest/minetest/pull/5154 |

jluc: cool, can it choose links by channel? |
| 22:27 |

jluc: hm, problem is it would only cover MT bugs, not MTG |
| 22:28 |
|
troller joined #minetest |
| 22:28 |
jluc |
as for now it provides only one set of urls (#issues and commits) for all chans it is activated |

pgimeno has the same nick color as paramat, which is slightly confusing |
| 22:28 |
