This is a question from someone who knows nothing about Lua. In your opinion, what's the most efficient and effective way of learning Lua?

Trying to use this code to mirror 2nd monitor in minecraft

So I found this video where a guy basically mirrored his second monitor irl to a monitor on minecraft. I figured out how to edit the part calling for what direction the monitor is in relation to the advanced computer. Now its attempting over and over but wont work. I think I need to set my monitor as a source but I dont know how to or what its called. Any advice?

I have fallen in love with luajit and is a shame that is so unrecognizable

Hi all, I've started this new job a year ago and our code base that work on is in lua. I never had any experience with it and I just thought it was a lesser version of python, now I think python is the lesser here.

What really made me fall in love was the moment I realized is all tables, packages? Tables, objects? Tables. Sugar syntaxes? Tables.

For me there is only a few languages that I care to like, if web then html,css,js; if performance or embedded then c/c++ and python for everything else. Now between I've seen how I was wrong, lua is better than python. Period. It merges the simplicity of code writing (no having to match vars type and returns, fixed memory, blabla) with the speed of C++ (because you can just import any fucking compiled library) like wtf lua should be way way way more used and advertised than python

Introducing civstack: the educational tech stack in the public domain, written in pure Lua!

https://civboot.github.io/index.html


I'm writing an educational tech stack in pure Lua and I've just reached a milestone: the build system is now itself implemented in pure lua, from which it bootstraps itself.

All of the main software is in an alpha/beta state: build system, version control, editor, documentation language (that's what renders the site), and find-replace tool.

I hope to be writing colored-text educational games by the summer. For folks who want to learn software engineering, getting involved in this project is a golden opportunity - help me develop a complete and learnable tech stack, and in the process help yourself learn to code!

Squish 5.2+ I forked and updated the squish module for Lua 5.2+ compatibility

GitHub link

I was looking to use a minifier for my own module I've been working on and knew about squishy, but from what I could tell it was only compatible with 5.1 and lower. I checked out some existing forks but didn't find anything that suited what I needed, so I adopted that "sigma-coder mindset" and did it myself.

It's literally just squish but made to work with Lua 5.2+

The biggest "change" I made is updating the documentation to be more robust, mostly for myself but in case anyone else was confused as to how to build/use it since it took me forever to completely understand.

Some features like `gzip` and `debug` I haven't touched and are just as they were previously. I wasn't going to get into that since they were already experimental features for the existing versions. I'll look into it in the future cause it sounds interesting.

Hope this can be useful to someone other than me!

Using ipairs() – antipattern? It cuts half of the table upon field nil assignment.

> a = {1,2,3,4}
> for k,v in pairs(a) do print(v) end
1
2
3
4
> a2 = nil
> for k,v in ipairs(a) do print(v) end
1
> a = {1,nil,3,4}
> for k,v in ipairs(a) do print(v) end
1
>

Commentary: *I know* about pairs() and ipairs(). But I would be _really_ expecting 1,nil,2,3 and not loosing half of my table because I reasigned something to nil.

Is it intended that every assignment after a[2\] = nil must be transferred to the hash part? It is sooo confusing.

Am I arriving at the right conclusion that using ipairs() might be an antipattern and I should stick to pairs or numerical for loop? Unless I am _really reallyyy_ sure that I have a LIFO-like table..?

lua lu

Can I get the readable text from a .lu file? I have the APK and everything is in the resource.car file, but the text inside is unreadable. I don't have a copy of the original code other than the APK, and I can't fix the errors right now because of that. Do you know of any way to do this?

Lua Gotchas

Hi folks, I've been programming with Python for about 2 years now.
My coworker suggested that start embedding Lua into my projects to speed up the slower parts(I think he is getting annoyed by some of the slowness lol). Anyone know something that might bite me in the butt that is easy to overlook? From what I understand, I can install Lupa and get the runtime like that. He told me to use a bunch of tables. Is that correct for the most part?

It’s a shame what seems to be happening to luau

I was in discussions with someone on what noscripting language to use for their game. The discussion eventually fell to luau vs lua 5.4.8, and Lua won out in the end. Not because it was necessary better, but because luau is associated with Roblox. It really sucks to see people completely dismiss a language because of external factors that have nothing to do with the language itself, and I fear that luau’s external influences doomed it for the rest of its life

That’s all, sorry for the rant.

I'm making a tool for making and distributing terminal apps that use Lua, what are your thoughts?

Hey guys! Right now I am making a tool for terminal apps distribution that heavily relies on Lua (since it's the language for coding these apps), will anyone need it? should I give up on it and do something else or should I continue working on it?

Basically, it's sandboxed Lua with some additional modules provided using C# (Lua CSharp), like those for using assets, calling other noscripts, permissions even (so that some sensitive functions like system.read_file_str require getting permission from user first (and yes, I removed io/os modules because sandboxing))

For more info, check the documentation for the tool's API: https://github.com/Ict00/TtyPack/blob/master/docs/main.md

I really hope to get at least some feedback, because right now I'm kinda blind and don't know what exactly do I do. :D

Hey everyone,

I’m working on a Garry’s Mod server that’s still in early development, and I’m looking for people who’d like to help out as a hobby / passion project.

* Gamemode noscripting
* Fixing or improving existing systems
* Helping build core server features
* **Model artists**
* Fixing or improving existing models
* Making better replacements

What you get:

* Credit for your work
* Long-term collaboration if things go well
* Freedom to share ideas and help shape the server
* Something you can use for your portfolio

If you’re interested, comment or DM me and I’ll share more details (concept, current progress, Discord, etc.).
Most of the progress is posted on discord.

Did I make a mistake by starting to learn programming with Lua?

Did I make a mistake by learning Lua instead of another programming language?
I'm completely new to programming, so I'm having some difficulties. Now I'm faced with a choice: continue learning Lua for Roblox game development or start learning Python/JS for web development.
