String Module

The original source code for this module was taken from the Wikipedia String Module but had to be re-written because the Wikipedia code used an overly general method for getting the function parameters that resulted in a null reference error. I simplified the argument referencing which solved the error.



Returns the length of the passed-in string.

local str = {}

function str.len( frame )
    local s = frame.args[1]
    return mw.ustring.len( s )

return str
