LuaDroid: why is some of the noscript not displaying in the output?

BACKGROUND ON THE OP:
I am quite new to lua. I've only been learning for a few days and I can grasp the basic principles of it. I have prior knowledge about coding and basic ideas as I'd learned most of python a few years back (I have forgotten nesrly all of what I had learned though).

I've been using roblox studio to learn when I'm at home but when travelling, I use LuaDroid. It is quite useful and, while I obviously can't practice stuff that need a 3d world and things that roblox studio has and LuaDroid doesn't, I can still practice if statements, maths, for and while loops, etc.

So anyways this is the issue: the noscript after line 61 (apart from comments because they don't appear anyway) just won't show up in the output. I've made a few functions after line 61 and then called them for use later but they aren't displayed in the output. I just don't understand why so someone please help me!

I'll paste my coding and what shows up in the output below. Also please tell me if I need to include more information about this because I don't know how much information you'd need to be able to tell me what I've done wrong.




Here's all of my coding (don't mind some of my word choices... hehe):




print("what the john is this")
-- thats the only thing i know how to do
-- how do i access lessons help
-- im cooked
print("im cooked")
print("heheheharr")
print("imma watch a tutorial 1 sec")

local function addOneLol(addOneTo)
resultA = addOneTo + 1
print(addOneTo, "add one equals", resultA)
return resultA
end

local function timesFive(multiplyMe)
resultM = multiplyMe 5
print(multiplyMe, "times five equals", resultM)
return resultM
end

timesFive(210)
timesFive(0.2525)

if timesFive(200) == 1000 then
print("guys 200 times 5 is 1000 no way")
else
print("news flash: my life is a lie")
end

local sigma = 0

for skibidi = 1, 10, 1 do
sigma = sigma + 1
print(sigma)
if sigma >= 5 then
print("yay")
end
end

print("5!")
end
end

local rizz = 1
while rizz < 6 do
print("this should be displayed 5 times")
rizz = rizz + 1
return rizz
end

-- uhh everything past this line doesnt work T-T

Lua on microcontrollers. Surprised how far it’s come

Been mostly using lue for small noscripting stuff over the years, config files, quick automation etc. Always loved how clean it feels but never thought of it as a serious option for embedded devices.

Recently tried out a setup where you run lua code directly on an esp32 and it honestly blew me away. Like full noscripting, GPIO access, MQTT, TLS, even OTA updates and all of it handled from a browser based IDE. Didn’t expect that level of capability from such a tiny chip running Lua.

Curious if anyone else here is experimenting with Lua on constrained devices? I know NodeMCU is a thing, but this felt a bit more full featured.

Putting my WebSocket into a Thread

## THIS IS A REPOST
Hi. I have been using https://github.com/flaribbit/love2d-lua-websocket/releases to create a simple websocket system for my Balatro mod. It all worked until some time ago. Only me on my laptop specifically and on the pc of a friend the game lags with 0fps. I have been able to pinpoint it to the löve2d socket library, specifically connect. I've learned that it's reccommended to put the socket in a Thread to avoid blocking operations stopping the game thread. I have never used threads in löve nor lua ever so I wanted to ask what would be the best way to rewrite my socket into using a thread without needing much of a refactor, since my code in this version is still spaghetti 🍝

How to list Windows pipes in Lua? (mpv)

Hi all,
I am trying to wait until a detached child process has created a named pipe, so that I don't send a command before the named pipe has been created (therefore making the command not take effect).

For this reason I am trying to list all the named pipes.

If I do dir -n \\.\pipe in the terminal (PowerShell), I get a list of all named pipes.

However, if I do the following in Lua (in an mpv noscript), I get nothing out:

for dir in io.popen([[dir -n "\\.\pipe"]]):lines() do print(dir) end

What's the best way to achieve what I'm trying to do?

Thanks

Getting Started with GTA V/FiveM Vehicle Mod Creation - Need Advice & Tutorials!

I’m running a FiveM server and want to dive into creating custom vehicle mods for GTA V/FiveM. I’m a beginner in this area and eager to learn the ropes. I’d love to hear from experienced modders about their process and any tips or basic tutorials you can share to help me get started. Specifically, I have a few questions:

1. Programming Languages: What programming or markup languages are commonly used for vehicle modding in GTA V/FiveM?
2. Essential Skills: What key skills or knowledge should I focus on to successfully create vehicle mods?
3. 3D Modeling Software: What are the best 3D modeling programs for creating or editing vehicle models?

Any personal experiences, beginner-friendly tutorials, or resources you can point me to would be greatly appreciated. Excited to join the modding community and start building some cool vehicles!

Thanks,

XLua vs Lua cysharp for game config files.

Can't understand what's the difference between XLua and Lua-CSharp. Which one will be more performant and gc-efficient for use in Unity? Specifically, I want to implement game configs with Lua. No complex logic, mostly numbers, strings, and some math. Something like Json on steroids.

I'm also wondering about performance: should I parse all the data from Lua into C# objects at application startup, or can I use objects directly from Lua noscripts in runtime? Accordingly, in the first option, it is better to use mostly static data and minimal logic in Lua?

Caelum Framework - A new structured way of writing lua

Hi, today i wanted to share with you a framework that i built in these weeks in lua: Caelum-lua. This framework was created with the objective to have a way to write lua noscripts that was easy to understand, even for programmers like me that have never coded in lua, and to make them easy to integrate in engines or other types of applications .

In fact the framework originated from a need of having a noscripting language for my future application that was fast, easy to use and to embed in my application, and that would give me a way of showing informations from the noscripts in the application editor.

This made me go for lua, but it lacked of a consistent information about types of the values created and used in the noscript, so it was difficult for me to show them in an easy and consistent form in the ui.

After weeks of developing, searching, and asking ai questions about the best tips and tricks for writing lua, it was born, the Caelum Library.

On this day the library has reached a semi-functional and ready-to-use state, so I wanted to share it with you, so that more people can give me opinions, critics, ways of improving it and also general advices on the lua programming language that I am learning to love.

pls help with list and for loop (imapfilter)

Hi everybody,

I am trying to clean up my `imapfilter` lua config. Total beginner, this is how far I got, but I cannot solve the final issue. Can you please help me?

results = {}

my_accounts = {
"one",
"two"
}

my_contain_body = { "Werbung" }

my_contain_subject = { "Wichtig" }

my_contain_from = {
"contact@bigdatacloud.com",
"Temu",
"Discord"
}

for each in pairs(my_accounts) do
-- FROM
for value in pairs(my_contain_from) do
table.insert(results, string.format("%s.INBOX:contain_from('%s')", my_accounts[each], my_contain_from[value]))
end
-- BODY
for value in pairs(my_contain_body) do
table.insert(results, string.format("%s.INBOX:contain_body('%s')", my_accounts[each], my_contain_body[value]))
end
-- SUBJECT
for value in pairs(my_contain_subject) do
table.insert(results,
string.format("%s.INBOX:contain_subject('%s')", my_accounts[each], my_contain_subject[value]))
end
end

I am able to run

for each in pairs(results) do
print(results[each])
end

in my test file and receive lines such as `one.INBOX:contain_from('Temu')`.

The last line in my `config.lua` is this

results:delete_messages()

When I run `imapfilter`, I get this

imapfilter: /home/me/.imapfilter/config.lua:210: attempt to call a nil value (method 'delete_messages')
stack traceback:
[C]: in method 'delete_messages'
/home/me/.imapfilter/config.lua:210: in main chunk

Can you please tell me what I am doing wrong? I was hoping I could automate creating the list instead of having it like this (current configuration)

results = (
one.INBOX:contain_from("Temu") +
two.INBOX:contain_body("Temu") +
one.INBOX:contain_from("Discord") +
two.INBOX:contain_body("Discord") +
-- (...)
)

The results list seems to include anything and everything I want (I can print all the expected values), but the `delete_messages` function does not work.

Thank you in advance for your help :)
