table.find

["Grisha" <grisha@...>]

The main reason I actually use it is to get variable name from it's value (in my case - a table).

The exact example is this (the dialog subsystem):

 

function offerchoice(...)

    ...

    if type(the_choice.select) ~= "function" then

        dprint("ERROR: " .. table.find(_G, the_choice) .. ".select() not found")

    end

    ...

end

 

choice_yes = {}

choice_no = {}

 

offerchoice(choice_yes, choice_no)

 

With respect,

Grisha
