I want to learn lua, need help
I want to learn lua from scratch, but nothing is installed and I don’t know anything about this language. Can someone send me stuff for learning lua please? (Videos, programming environment, docs,…)

Updates on Caelum
A week ago a made a post on this reddit in regards of a library that I am creating, Caelum, after that post i added more features that made me realize that this project is getting bigger and bigger, when in reality it was meant to be only a small library to help integrate lua in my engine.
At this point I am asking myself, is anyone really interested in a library such as Caelum-lua?
With this question in mind I wanted to make this new post in this reddit to understand more the lua vision and the lua-programmers as a programmar myself coming from a totally different type of programming "habitat".
Let me know your real opinion on the library, where you think it should go, maybe features that are too much or not really lua-centrinc that should be removed, features that you would like to see in a library like this, and if you like you can also bring your ideas directly to the github repo, as I said in the previous post, I would like to expand this library with a community driven vision and ideas.
Feel free to ask any question!
Thank you for your attention, and sorry if it is not really a topic on lua but more on the development path of a library

Which tools do you use in your Lua projects?
I'm new to Lua and have found StyLua for formatting and selene for linting. Are these the best options? Are there any other tools I should be using?

_G and _ENV
Hello. I am reading the chapter about environments from *Programming in Lua, 4th edition*, and also did online searching regarding `_G` and `_ENV`. Here are my observations and experimenting for record. Feel free to comment if you have something to add or correct.
* The `_ENV` is a local variable for the compiled chunk but can simulate a *global* environment by the compiler's mechanism of prepending all free names with `_ENV.` . Creating and accessing a global variable e.g. `a = 5 print(a)` is equivalent to `_ENV.a = 5 print(_ENV.a)`.
* The `_ENV` is initialized to be the same as `_G`, because `_G == _ENV -- true` (having the same memory address).
* `_ENV` contains a field of `_G`, and `_G` contains a field of `_G` as well.
* A global variable assignment such as `a = 5` puts a key of "a" and value of 5 in `_ENV` and `_G` simultaneously because they are still the same table. Evidenced as below:
​
print(_ENV) -- table: 0x6000017d8040
print(_G) -- table: 0x6000017d8040
a = 5
print(_ENV.a) -- 5
print(_G.a) -- 5
print(_ENV) -- table: 0x6000017d8040
print(_G) -- table: 0x6000017d8040
The result is the same if `a = 5` is replaced by `_ENV = 5` or `_G = 5`.
* However, if `_ENV` is assigned a new table, the memory addresses of `_G` and `_ENV` will be different, but the rule that the *global* environment is `_ENV` still applies.
* Example of overriding the \_ENV:
​
print(_ENV) -- table: 0x600001844200
print(_G) -- table: 0x600001844200
_ENV = {_G = _G, print = _ENV.print} -- can also be print = print or _G.print
print(_ENV) -- table: 0x600001840140 -- different from before
print(_G) -- table: 0x600001844200
a = 5
print(a) -- 5
print(_ENV.a) -- 5
print(_G.a) -- nil
In this case, `_G` will be prepended as `_ENV._G`, but since it was never added the field of "a", `_G.a` is `nil`.

Need beta testers for HRAM (hand-rolled assembly machine)
Hi everyone. I'm making an app called HRAM (hand-rolled assembly machine), and I plan to release it this week. But I need some beta testers first. Please send me an email at admin@90s.dev if you're interested. Your feedback will be helpful enough that I'll give you a free license. The app is only for Windows (10 or 11).
The app is programmable via Lua and has an assembly library built in, so you can create and run assembly functions at runtime. It has a 320x180 pixel screen that you can manipulate to help you practice assembly. The point of the app is to help learn low level concepts, in the fun environment of making a retro style game. I'm also in the process of adding threading/mutexes/etc also, but that may have to wait post release.
Current manual is at https://hram.dev/docs.txt

Can someone make a code that makes my gun recoil in the opposite direction to where I'm pointing please?
Excuse me for asking this here, but I'm trying to make a Terraria weapon in Gmod, and as a secondary attack, it makes a noise like the Tau-Cannon and sends me far back. If someone can do it or give me instructions on how to do it, I would appreciate it. Thanks in advance.
I'm not uploading the code because it won't let me for some reason

Beginner code question on nested tables
I am trying to construct and print a nested table In this simple example:
#!/usr/bin/env lua
company = {director="boss",
{address="home",
{zipcode ="12345"}
}
}
print(company.director) --> boss
print(company.director.address) --> nil - was expecting 'home'
print(company.director.address.zipcode)
print(company"director") --> boss
print(company"director""address") --> nil - was expecting 'home'
print(company"director""address""zipcode")
It prints nil where I was expecting it to print 'home'.
What am I doing wrong?

Sol2 and Modules
What are your thoughts on using cpp and sol2 library to create Modules to use in lua noscripts?
Do you prefer a Module written in c/cpp with the pure lua api, or Is It ok to use sol2?

Luans - a Lua Learning App inspired by Koans (beta)
Hey everyone,
We’ve created a small web app to help people get started with Lua: [**play.tenum.app**](https://play.tenum.app)
It’s inspired by Kotlin Koans — we’re calling it **Luans**.
Each exercise is structured as a failing unit test, and your goal is to make it pass. The idea is to learn Lua through hands-on practice, one small step at a time.
Right now, the app is super basic and only contains a few lessons. We're testing right now and would love to hear from this community:
* Is this format helpful for learning Lua?
* What kinds of exercises or topics would you want to see?
* Are there other Lua learning platforms/tools you’ve used or recommend?
We’re considering investing more time into it, so your feedback would mean a lot.
Thanks in advance

Working on a Wireshark parser, why does TreeItem:add_le() not reverse strings too?
My first instinct would be to post to r/wireshark, but last time I had a similar question I was directed here. Apologies if that’s incorrect.
[Link to line in docs](https://www.wireshark.org/docs/wsdg_html_chunked/lua_module_Tree.html)
Trying to fetch a little endian string, but it’s reversed because apparently the little endian add function only works on numbers? This feels really wrong, I can’t imagine why it works like this. Let me know if a more elegant way to display this is known.

How do I get better in Algorithms/Problem solving in Lua?
I started solving ''LeetCodes'' ( just LeetCode style coding puzzles, generated by ChatGPT since there is no Lua support for LeetCode) about just over a week ago. While I thought I finally got mastered for loops and tables, I now realize that my problem solving skills just suck and I would just keep failing most of the easy difficulty questions... For context, the average easy question would be something like finding the longest substring with no recurring/repeating letters or finding if a string is an Anagram, some other stuff with numbers like finding two pairs in a table that equal to target using just one for loop and other stuff that like that all of which require Hash tables which I really suck at... I have no idea what I can do to improve, other than just keep asking ChatGPT to explain stuff in more detail which it either can't do properly or I'm just too stupid for this... Sadly, unlike other languages, apart from having no LeetCode support, there are also minimal Lua tutorials when it comes to this kind of stuff, 0 on YouTube as far as I'm concerned so I just don't know how to progress with it. Maybe I am just stupid lol, I found a 7th grader the other day cranking c++ LeetCodes like the fucking legend he is, meanwhile I'm out here struggling to solve a LeetCode in what is possibly the most high-end programming language known to man... Any tips on getting better with algorithms and stuff like that in general and mainly mastering it inside Lua?(any good places to find tutorials maybe??) Also how do I get more used to hash tables and known how to use them properly? (additionally, I would ask whatever ''time complexity'' is but maybe that's a lesson for another a time) Basically how do I adapt to all of those situations I'm just so lost...
Any help will be appreciated! Seriously... D:

why isint eof a vaild statement?
i am very very new to lua (about 3 days into learning) and an error in the console is saying that it is excpecting <eof> but recived end and when i try to fix the error i figure out that eof isint a vaild statement (not sure if that is the right term) having the valid statements being colored to match the statement
