Calling a function from a string

[CrimboJimbo]

I have a file uploaded to github that I am trying to call a function out of. The format is: [Key] {Function}. I search through the document to find the correct key then pull the function name out of the {} but is refuses to call the function with that name. I have been looking online for was to do this with things like, _G[c]() but I have had no luck.

My current code is as follows:

local input = read() --Replace with input from chat
local request = http.get("https://raw.githubusercontent.com/CrimboJimbo/MinecraftDadBot/refs/heads/main/Dad%20Commands.txt")
local inputMod = string.lower(input)
local txt = request.readAll()
local a,b,c
-- print(txt)
function TestFunc()
    print('Yippie!')
end

print(inputMod)
a,b = string.find(txt,inputMod)
if a == nil or b == nil then
    error("idiot")
else
    a,b = string.find(txt,"%b{}",b+1)
    print(a,b)
    c = string.sub(txt,a+1,b-1)
    -- local scrum = load("return function() "..c.." end")
    -- local ok, scrim = pcall(scrum)
    -- print(ok)
    -- _G.scrim()
    _G[c]()
end
request.close()

The print output show that c = TestFunc() but nothing works when trying to call the function. I've also tried to remove the () inside the c string but I get the same error messages. any ideas?

Just for context I'm working on an in-game chat bot called DadBot. The path for the TxT I'm using is: https://raw.githubusercontent.com/CrimboJimbo/MinecraftDadBot/refs/heads/main/Dad%20Commands.txt

local scrim defines a local variable, which not exists in _G. Therefore you cannot do _G.scrim(), but just invoke scrim() is what you want

Can you re-paste the latest codes and the output again?

Edit: Sorry, I forgot to revert some testing I was doing, this is the code that shows the most promise currently

write(">")
local input = read() --Replace with input from chat
local request = http.get("https://raw.githubusercontent.com/CrimboJimbo/MinecraftDadBot/refs/heads/main/Dad%20Commands.txt")
local inputMod = string.lower(input)
local txt = request.readAll()
local a,b,c
-- print(txt)
function TestFunc()
    print('Yippie!')
end

print(inputMod)
a,b = string.find(txt,inputMod)
if a == nil or b == nil then
    error("idiot")
else
    a,b = string.find(txt,"%b{}",b+1)
    print(a,b)
    c = string.sub(txt,a+1,b-1)
    Scrum = load("return function() "..c.." end",nil,"bt",_G)
    Ok, Scrim = pcall(Scrum)
    print(Ok)
    Scrim()
    -- _G[c]()
end
request.close()

CC's _ENV and _G are different tables, unlike in base lua. You want to pass _ENV instead of _G.

[fatboychummy]

To clarify, when you declare a variable (or function) without the local keyword, Lua always puts the value into _ENV. This is the case in CC as well, but CC creates an _ENV that is specific to each program, then an actual global _G (whereas in base lua, both tables are the same).

If you want something put in _G instead of _ENV, you need to prefix your declaration with _G., i.e: _G.variable = "global variable"

That was it! Thank you!
