Lua Debugger Project

[Edit: I'm dumb, here's the link to the project https://github.com/NewbySlime/Lua-Debugger-GUI\]

Hey, I wanted to share something. This is a GUI debugger tool for Lua 5.3 using Godot 4.3, I've been working on this debugger for a while. Since I need people to test the project out, I wonder if I can get some traction going by posting it here.

NOTE: for now, only works for Windows.

Also bear with me when it comes to Github stuff, this is "kind of" my first time creating a kinda big project.

Note: my time here is night, any issues will be processed the next morning (my morning). Thanks!

Oh and, I'll be thankful to anyone contributing to the project <3

Where learn lua

Hello I just want to know where I start learning lua and simple project I can made

https://redd.it/1iia6pl
@r_lua

TAL - a pseudo-runtime for lua, written in lua

[https://git.topcheto.eu/topchetoeu/tal](https://git.topcheto.eu/topchetoeu/tal)

This is a small runtime made to build on top of the, quite honestly, insufficient and incomplete lua stdlibs, as well as the annoying non-relative module system.

It is written for my personal usage and so it's pretty shitty and undocumented, some pretty questionable decisions have been made to make this working. The code base follows no sane standards and will probably break a lot of existing lua code - TAL is definitely far from prod-ready.

Some of the major features it has are:

* symmetric coroutines (by utilizing a modified version of "coro")
* a better module system
* extensions of the standard libraries, most notably the new "array" class
* some useful modules
* an event loop (still useless because there are no async functions yet)

Feel free to check it out and give me your feedback - should I clean this up for usage by sane people?

Also, the name means "TopchetoEU's Atrocious Lua"

how do event loops work in terminal and how to implement them? (please help im bashing my head in)

I come from a JS background and I am pretty new to lua and terminals, i have a basic terminal application. I wanted to understand how you would go about implementing let's say a progress bar that runs in a nonblocking way, right now the progress bar runs but you cannot do any tasks or add an input while the progress bar runs, I have been trying to implement it but i am honestly just confused, I wanted a functionality like this:

==============40%
press 'q' to go back

You can switch between the menu while the progress bar runs.

Here's the code for the main application and the progress bar ui file :

main.lua

local sys = require("system")
local UI = require("ui")
local copas = require("copas")

function displayMenu()
print("=============")
print("1. Check Time")
print("2. Get Mono Time")
print("3. Give Feedback")
print("4. Progress Bar Demo")
print("6. Exit")
print("=============")
end

function sleep()
local input = io.read()
local gotInput = sys.readkey(input)
print(gotInput)
end

function getTime()
local time = sys.gettime()
local date = os.date("Current Time: %Y-%m-%d %H:%M:%S", time)
print(date)
end


function monoTime()
local response = sys.monotime()
print(response)
end

function UI.prompt(message)
print(message .. " (yes/no):")
local response = io.read()
if response == "yes" then
return true
else return false end
end

function uiPrompt()
local response = UI.prompt("Do you like lua?")
if response == true then
print("Thats great!")
else
print("So sad to hear :(")
end
end

while true do
displayMenu()
io.write("Select an Option: ")
local choice = tonumber(io.read())

if choice == 1 then
getTime()
elseif choice == 2 then
monoTime()
elseif choice == 3 then
uiPrompt()
elseif choice == 4 then
copas.addthread(
function ()
local total = 100
for i=1, total do
UI.progressBar(i, total)
copas.pause(0.1)
end
print()
end)
elseif choice==6 then
break
end
end

copas.loop()

ui.lua

UI={}

function UI.progressBar(current, total)
local widthOfBar = 50
local progress = math.floor((current / total) widthOfBar)
local remaining = widthOfBar - progress
local bar = "[" .. string.rep("=", progress) .. string.rep(" ", remaining) .. "]"
io.write("\r" .. bar .. math.floor((current / total) 100) .. "%") -- carriage return for progress bar to stay on the same line
io.flush()
end

copas.loop()

return UI

If anyone could explain and point out what i am doing wrong that would be great. Thanks!

How possible is to make programs with Lua?

I'm learning to code to make games, and Lua is one of the languages that interest me, as some say Lua is easier than Pythom to learn. What I see often, however, is that Lua is designed to be enbedded into other languages, as oppose to be used on it's on.

Is it possible to make complete programins purely on Lua?

Lua modding

Does anyone know or have experience modding Sims 4 in lua? I have been learning lua for a bit and wonder if its possible to mod sims 4 with this programming language.

https://redd.it/1ijxjl2
@r_lua

I've only been learning for a short time, but I love physics so I tried this

Is it good for a beginner?



--define the root function
function root(x)
return math.sqrt(x)
end


--- light constant
c = 310^8

--get the values
print("how many percent of the speed of light")
v = (tonumber(io.read())/100)c
print("what is the mass of the object(kg)")
M = tonumber(io.read())


--calculate lorentz value
LorentzFactor = (1/root(1-(v^2)/(c^2)))


--simplify the variable
F= LorentzFactor


--see if the value is less than the speed of light
if v >= c+1 then
print("               $ERROR.0".. math.random(1,10).. "$;enter a valid value (<= c)")
-- here checks if the value is equal
elseif v == c then
print(" $ERROR.0"..math.random(11,15)..";value approaches infinity")
--aki checks if the value is negative
elseif v <= -1 then
print("ERROR.016;identified negative value")

else
--energy calculation
E = (F - 1)Mc^2
--print the energy
print("the energy of the object is "..E)

Thoughts on roblox as a free way to learn?

What are your thought son roblox studio and the platform itself, from a developer's perspective?


I'm leaning towards roblox but ive also considered love2d or some fantasy console.

I like lua and i want to learn the basic of it. ive messed with roblox but im not sure if i should stick with it. ive also never finished anything in studio.

Why did you guys decide to learn Lua?

Basically noscript.
I’m just curious to learn why other people decided to learn Lua. For me it’s for my work (I work as a robot programmer and I need to learn how to write some noscripts). I’m just starting out and I think it’s kinda fun.
Do you have any tips and or insights for a newb?
