Re: how to call a local function by its name?

[Brigham Toskin <brighamtoskin@...>]

Other than a name-to-function mapping table (like in your first example), I don't think there's a way to do this directly. You could use loadstring() to invoke a function by name, it has to be visible form the compiled function's context, which won't have access to your locals. It would also be inefficient, if you have to do this a lot.

example with table of functions:

local T = {}

function T.func1() print("func1") end

function T.func2() print("func2") end

local fn = { "func1", "func2", "func3" }

for i = 1, 3 do

local func_name = fn[i]

pcall(T[func_name])

end

it is work, but I'm interested in the ability to call a local function:

local function func1() print("local func1") end

local function func2() print("local func2") end

local fn = { "func1", "func2", "func3" }

for i = 1, 3 do

local func_name = fn[i]

pcall(func_name) -- ???

end

of course, I get an error "attempt to call a string value".
