lua call function from a string with function name

Question

Is it possible in lua to execute a function from a string representing its name?
i.e: I have the string x = \"foo\", is it possible to do x() ?

Answer 1

It sounds like you want to do an 'eval', which is supported in Lua like so:

assert(loadstring(x))()

You'll probably want to concatenate the "()" onto x first, though.
