I was wondering if its possible to get arg types from a function without calling it.
e.g
local function f(a: string, b: number, t: {})
print()
end
is there a way to get the types of the arguments (a: string, b: number, t: {}) without calling the function?
There isn’t any way (That I’m aware of) to get the type information from a function; What’s your use case?
If you’re planning to reuse type information from a function, you can use typeof to get the type of the function:
local function foo(a: number) : ()
--...
end
local bar: typeof(foo) = function(...) -- `bar` will have `foo`'s type information
--...
end
Are you looking for something like this?
function SoMany(...)
--[[
to get individual args just use this
]]
local arg = table.pack(...)
print(arg[1].. " string")
task.spawn(function()
for _,v in arg do
print(type(v))
end
end)
print(...)
end
SoMany("text", true, Player.Name, workspace)
Using meta-information like that is generally frowned upon, since there’s always a better way of doing it.
What do you need this for?
For a remoteevent, depending on if the data is correct (secured) it will call a function. One of the checks is going to make sure that all the data passed through the remote event to the server has the same arguments as a certain function. I thought It would be possible because we can get the number of args with debug.info, so why not the values?
@HugeCoolboy2007 Interesting, but not what I’m looking for
@weakroblox35 I’m trying to get arguments directly from a function without calling it
