i am sorry for ask something like this, but i did not understand which function of lpeg i should use to parser a string which contains a lua code sample

local code = [[
   --some lua code here

i tried print(lpeg.match(lpeg.P(lua), code)) but it prints just the index of first character after the match or nil if the match does not occur

I need a error message like those showed by lua interpreter when it find a syntactic error, instead the nil value printed . How can i get this errors messages using the lpeg and the Lua Parser code found on this page

Am I missing the point, or do you just need to use the standard function loadstring ( ) ?
