Is there a way to put every part of a lua in 1 line after coding it?

I made a lua (about 4600 lines of code) and i want to put it in 1 line so people can’t steal the code as easily, how can i do that?

Working with WebRTC from fengari lua in the browser...first steps

I decided to create this simple RTCDataChannel example in lua using fengari. The most interesting part of this process was figuring out how to translate the promise-chaining as seen here:

localConnection.createOffer()
.then(offer => localConnection.setLocalDenoscription(offer))
.then(() => remoteConnection.setRemoteDenoscription(localConnection.localDenoscription))
.then(() => remoteConnection.createAnswer())
.then(answer => remoteConnection.setLocalDenoscription(answer))
.then(() => localConnection.setRemoteDenoscription(remoteConnection.localDenoscription))

Reading Text in a Status Bar

Greetings, I’m looking for a way to read text from another window, in particular the status bar. I currently do this with an AHK noscript using the StatusbarGetText command. It works well enough but I’m considering switching from Windows to Mac and that means moving away from AHK. This is all for populating an OBS scene so doing it directly in OBS with a lua noscript felt like a good place to start.
If statusbar reading is not possible, I’d be open to other methods, but text files wouldn’t be quick enough.

I realise I haven’t explained the background very well so here is what I currently have set up.
I use a custom build of an emulator to play games and the emulator displays various information in the status bar from the game. An AutoHotKey noscript I made constantly reads the status bar and does various things with it. Some of which is graphical (which OBS displays via window capture) and some (things that can be slower) are exported to text files that OBS, again, does various things with. It’s a bodge, but it works, but as mentioned, I’m wondering if I can now remove the AHK element and have just the emulator and OBS(with lua noscripts)

I’d really appreciate any input. Thanks.

Please help me learn Lua

I recently switched to Arch Linux, before macOS, where I came into contact with Neovim, Awesomewm, etc., all of which are configured in lua, I myself have learned C, java, etc., and I think I can skip the basic syntax stage when learning lua.

I also tried to find some ways to learn Lua on the Internet.,And then I went to check and learn some big guys' profiles.,But I found that I couldn't understand it.,Of course, some configuration files I put on my computer can also run normally.,But if you want to customize some functions,,I can't do it at all.。

I don't know how I'm going to access the learning lua, please help me!

Lua docs

Hello, I've been learning Lua through docs and I came across this example: https://www.lua.org/pil/10.1.html

db.lua file is calling entry function with the table containing data and in this case they are calling dofile() twice.

I am aware that lua compiles fast but my question is: is there an advantage to doing things this way instead of making db.lua return a table, calling require('db.lua') once and simply passing the table to both entry functions?

Help understanding header of a function

I'm trying to understand what the "&" in this function header means

void ChangeColor(const struct FLinearColor& New_Blade_Color, const struct FLinearColor& New_Blade_Glow_Color);

The FLinearColor struct contains 4 attributes (R, G, B and A), all of which are floats; But whenever I try to use the function by passing a table to the parameters it defaults all of them to 0

Hero[2]:ChangeColor({0.9, 0.9, 0.9, 0.9}, {0.9, 0.9, 0.9, 0.9})
(When I access the variables changed by the function they all print '0.0')

What am I doing/understanding wrong here?

Obfuscators

Hello everyone,

I decided to create a Discord bot that works as a Lua obfuscator. This is interesting to me because luaobfuscator.com crashes quite often. The bot uses the free API from luaobfuscator.com to obfuscate files uploaded in the server.

It’s no secret that luaobfuscator.com doesn’t provide very strong obfuscation, just something basic to deter skidders. However, if someone really wants the source code, they can still access it without much effort.

I’m looking for a Python-based obfuscator or websites offering APIs for Lua obfuscation. Any help would be appreciated!

Need help with a recoil noscript

I downloaded this recoil noscript for Rust. It works fine except for the fact that I need to double click in order for the recoil compensation to kick in. So essentially when I click once it compensates the recoil, but when held down it doesn't work. If I click once and then hold down mouse 1 RIGHT after it, it works.

I need a high IQ individual to help me out here, im not familiar with coding and even tried to ask ChatGPT for help but to no avail. :(

Heres the code:

end

function Sleep_extra(gun, a)
local b = GetRunningTime() + a
repeat
if IsMouseButtonPressed(gun) then
break
end
until GetRunningTime() > b - 1
end

function round(x)
return x >= 0 and math.floor(x + 0.5) or math.ceil(x - 0.5)
end

Any tools to read Lua source, parse the LuaDoc in it, and spit out a data structure of the results?

I'm writing a program that would benefit from being able to read the LuaDoc in a lua source file. I first tried to set up a regex to do this but it would wind up being gigantic and not worth the effort. Are there any such tools out there? I need it to give me a list of the functions and whatever params the user supplied in the LuaDoc.

For example:

---Begin fishing at a spot, allowing the player to click the fishing reticle
---to "complete" the attempt. This function must be called outside a coroutine.
---@param fishList FishableList The list of fish. Preferably, return results of calling Fishing.Find.
---@param junkList JunkableList The list of junk.
---@param reticlePointEntity Entity The point entity where the fishing reticle will spawn.
---@param fishingRod Entity The fishing rod entity, which will be hidden during fishing.
---@param consolationLootTable string Loot table to use as a consolation prize (unsuccessful fishing outcome but there was a fish in the reticle).
---@param catchCallback? function Function to call when catching a fish, with a single entity argument. This will be called in a coroutine.
function Fishing.Setup(fishList, junkList, reticlePointEntity, fishingRod, consolationLootTable, catchCallback)

I need back the function name Fishing.Setup, along with all args and their given types, for all functions in a file.

There seem to be tons of LuaDoc doc makers out there but nothing that kinda specifically stops at just exporting the data in a more programmer-friendly fashion.

Simple table assignment in for loop not working.

Hey,
I have a decent amount of programming experience, and am trying to learn some lua (for DCS noscripting) But just quickly going through the basic tutorials I ran into a problem. For some reason this simple code, which should just reverse a table won't work:


days = { "monday", "tuesday", "wednesday", "thursday", "friday", "saturday", "sunday",}
revDays = {}

for i,v in ipairs(days) do
revDaysv = i
print('Adding weekday "' .. v .. '" with value: ' .. i)
end

for day,index in ipairs(revDays) do
print(" day " .. day .. " has index " .. index)
end

I know I'm probably missing something obvious, but for the life of me I can't figure it out.
The code itself is copy-pasted from https://lua.org/pil/4.3.5.html

Why does Lua have ipairs ?

I am aware of the difference between pairs() and ipairs() but seeing another post here today I was wondering why lua actually has ipairs.

t = { "a", "b", "c", "d"}

for i,v in ipairs(t) do

print(i, v)

end

for i,v in pairs(t) do

print(i, v)

end

does exactly the same thing after all. I always use ipairs for non-dictionary arrays but is it actually worth it? Is there a minimal memory advantage or performance difference?
