Help needed - luarocks test --prepare always erroring on Windows

I'm trying to install a package luarocks. Specifically I want to

1. clone my package
2. install all of its dependencies
3. install all of its test_dependencies
4. run the unittests (via busted)

My understanding is that I can do #2 and #3 by calling luarocks test my_package-scm-1.rockspec --prepare and then do #4 with luarocks test --test-type busted. #4 is working fine. My problem is with #3. And possibly #2.

I simply cannot seem to get luarocks test --prepare to run on Windows. It looks like despite the luarocks test --help documentation saying that --prepare does not run any tests and just installs dependencies, it looks like --prepare still actually does run some tests. In my logs I can clearly see Error: test suite failed

This is the GitHub workflow run: https://github.com/ColinKennedy/mega.vimdoc/actions/runs/12772422930/job/35601914793

And the logs are here

And the GitHub workflow file

From what I can guess from reading luarocks source code, it looks like unittests are running for some package, somewhere, and instead of showing the error it's just defaulting to the generic Error: test suite failed error message that can be seen in the logs.

[noob] Replace single space in between non-space characters with wildcard

How to replace a single space (` `) in between non-space characters with `.*`?

I'm writing a simple Lua wrapper (I don't know any programming) to rebuild the string that gets passed to rg (grep alternative) where a single space between non-space characters imply a wildcard. To use a literal space instead of the wildcard), add another space instead (i.e. if the wildcard is not desired and and a literal space is wanted, use 2 spaces to represent a literal space, 3 spaces to represent 2 spaces, etc.).

Example: `a b c d` becomes `a.*b.*c.*d`, `a b c d` becomes `a b.*c.*d`.

I have something like this so far `query:gsub("([^%s])%s([^%s])", "%1.*%2")` but it only results in `a.*b c.*d` (`word word word word` correctly becomes `worda.*wordb.*wordc.*wordd` so I don't understand why) .

-----

For handling literal spaces, I have the following:

local function handle_spaces(str)
str = str:gsub(" +", function(match)
local length = #match
if length > 2 then
return string.rep(" ", length - 1) -- reduce the number of spaces by 1
else
return " " -- for exactly two spaces, return one space
end
end)
return str
end

im a stupid windows user and need help with luarocks

Basically im trying to install the package cjson with luarocks, running the following command:

Error: Build error: Failed installing cjson.dll in C:\lua\bin\bin/../share/luarocks/rocks/lib/luarocks/rocks/lua-cjson/2.1.0.10-1/lib

Im sure the error lies in the LD of gcc, but ive never ran in to this problem. Im confused, can someone help, please?

Import module to use in Lua interactive mode question

I am completely new to Lua. I want to use a lib call eff.lua. By following its instruction, I install this lib using $ luarocks --local install eff. It accomplished installation successfully.

Installing https://luarocks.org/eff-5.0-0.src.rock
eff 5.0-0 is now installed in /home/ubuntu/.luarocks (license: MIT)

However, when attempting to load/ import and use the module in interactive mode after executing the lua command, the lua interactive mode displays errors.

$ lua
Lua 5.1.5 Copyright (C) 1994-2012 Lua.org, PUC-Rio
> require "eff"
> local Write = inst()
stdin:1: attempt to call global 'inst' (a nil value)
stack traceback:
stdin:1: in main chunk
C: ?

I thought it is because the path problem in the first place. The require "eff" looks working. So I am confused.

How can I fix this error? Thanks.

Alchemer Lua set url variable or custom variable

This is driving me crazy. Even with an if else statement I cannot figure out how to evaluate two variables and set one of them. Any help is greatly appreciated

This is what I have:

questionID = 111
-- Get the values from the URL and invite
urlval = urlvalue("reg") inviteval = 'invite("custom 5")'
-- Determine which value to use
if urlval ~= nil and urlval ~= ""then
value = urlval
elseif inviteval ~= nil and inviteval ~= "" then
value = inviteval
else
value = nil
-- Set the value for the question
if value ~= nil then setvalue(questionID, value)
end

Como colocar dierentes consequências em uma mesma condição (if) quando programo em lua?

Olá! Estou fazendo o que posso para aprender a programar usando lua. Nunca programei antes, mas espero que consiga adicionar essa habilidade ao meu portifólio de ferramentas, e quem sabe até fazer um joguinho no roblox com ela.

Enquanto fazia um código para praticar, me deparei com um problema: não consegui escrever várias consequências para um só if. Isso fez com que eu tivesse de extender um parágrafo a três. Isso foi feito para ser assim ou há alguma maneira de fazer em um só parágrafo?

if EFT == true then

HP = HP + 20

elseif TLT == true then

HP = HP + 5

elseif EFT == true if TLT == true then

HP = HP + 25

end

if EFT == true then

TTpoints = 10

elseif TLT == true then

TTpoints = 5

elseif EFT == true and TLT == true then

TTpoints = 10

end

if EFT == true then

XPproductionVR = 2

elseif TLT == true then

XPproductionVR = 8

elseif EFT == true and TLT == true then

XPproductionVR = 4

How do I call a recursive function multiple times?

```
local pair = function(n)

return n * 2, math.floor(n / 3)

end



local get_id = function(n)

local r = {}



r.rec = function(n)

local a, b = pair(n)



if a == n or b == n then

return "reached" -- I will do stuff here once I figure out the problem

else

tree.rec(a)

tree.rec(b)

end

end



return tree.rec(1)

end



print(get_id(20))
```

I am trying to make a function that will recursively climb up the collatz conjecture tree checking every value for the number I entered "20". Basically, I want this to assign a unique number to every collatz tree number. My problem is that tree.rec(a) is always being called first and tree.rec(b) is never called in the function.

OOP "static" functions – terminological confusion?

Hello! I dive into the world of going OOP in Lua.

I understand most about .__index, metatables, prototypes etc.

My question is methodological though about content of certain guides.

Many online guides to OOP (like this one) talk about "static" functions. However, if you have a class

-- Create the table for the class definition
local ExampleClass = {}
ExampleClass.index = ExampleClass

function ExampleClass.new(name)
local self = setmetatable({ name = name }, ExampleClass)
return self
end

function ExampleClass.static()
print("Inside Static Function")
end

function ExampleClass:method()
print(self.name .. "'s method.")
end

-- Prints "Inside Static Function"
ExampleClass.static() -- works as expected

local instance = ExampleClass.new('Named instance')
instance:method()
instance.static() -- unexpected/wrong???

-- Deleting self-referencing class index doesn't help:
ExampleClass.index = nil
ExampleClass.static() -- works as expected
instance.static() -- throws error (good!)
instance:method() -- ALSO throws error (bad!)

The issue here is that static function CAN be accessed from the instance while they shoudn't.

If I understand correctly, this is because "methods" live in class table, which is instance's metatable and referred whenever something is not declared in instance table. This makes it even worse: all the static properties are also accessible from instance. Thank's God they point to the same reference 😳.

Is there an established way to have "true" static functions in Lua? Or is this concept pretty much misused?

I know that Lua's OOP is often most-likely prototype based. But so is e.g. JS where still static is a static:

class Class {
constructor() {
this.prop = "";
}
static staticFunction() {
console.log("static");
}
methodFunction() {
console.log("method");
}
}

let instance = new Class();
Class.staticFunction(); // works
instance.methodFunction(); // works
instance.staticFunction(); // ERROR: not a function

Just started learning - could use some help explaining some things

I have little experience in languages like Python and Java but wanted to learn Lua to make Roblox noscripts along with 2D games. I want to start off by just learning Lua as a whole. I've been learning for the past 3 days now (7 hours coding, and about 2 hours watching videos). Something that I'm struggling to get is the for and repeat loop, along with tables.

for a for loop the only thing I can do/make is:

for i = 1, 10 do
print("Hi.")
end

for tables, I try to make word-guessing games, or guess the length of a word but always have issues calling it from the table

local words = {
    "Dog", "Wire", "Mountian", "Tree", "House", "Car", "Bike", "Plane", "Boat",
    "Train", "Donkey", "Cat", "Fish", "Bird", "Lion", "Tiger", "Bear", "Wolf", "Fox", "Rabbit", "Horse",
    "Cow", "Pig", "Sheep", "Goat", "Chicken", "Duck", "Goose", "Turkey", "Penguin", "Ostrich", "Eagle", "Hawk",
    "Falcon", "Owl", "Parrot", "Crow", "Raven", "Seagull", "Dove", "Sparrow", "Robin", "Bluejay", "Cardinal", "Woodpecker",
    "Hummingbird", "Swan", "Pelican", "Flamingo", "Stork", "Crane", "Heron", "Ibis", "Vulture", "Condor", "Albatross", "Puffin", "Pigeon", "Starling", "Nigger"
}

io.write("Select a letter: ")
local userLetter = io.read():upper()

local matchingWords = {}
for , word in ipairs(words) do
    if word:sub(1, 1) == userLetter then
        table.insert(matchingWords, word)
    end
end

if #matchingWords > 0 then
    print("Words starting with '" .. userLetter .. "':")
    for , word in ipairs(matchingWords) do
        print(word)
    end
else
    print("No words found starting with '" .. userLetter .. "'.")
end
