Call function using variable as function name

[=475FG= Dawger]

I need to call functions using a variable to store the function name and then call that function using the variable.

Anyone know how to do this?

There you go:

-- a random function
function random_function()
    return 42
end

-- name of random function as a string variable
local function_name = "random_function"

-- recover the original function
local recovered_function = loadstring("return " .. function_name)()
-- CAN BE REMOVED: just to prove both functions are identical
assert(recovered_function == random_function)

-- call the recovered random function
return recovered_function()

It could be defined in a table and then you just reference that table entry when calling it. 

local tbl = {}
function tbl.doWhatever()
   env.info("hello world")
end

for fcnName, _ in pairs(tbl) do  -- super lazy example
     tbl[fcnName]()
end

Thanks for the suggestions.

What I have working at the moment is this:

_airbaseNeutral = _airbaseName..'Neutral'

_G[_airbaseNeutral]()

Apparently, this works for functions in the Global namespace.
