Thanks for the reply. I looked at the Lua source code already. But since that is in C it runs a lua state and effectively when the code is executed the lua state is in pause at least that is how I understood it which means that if you write an incomplete statement and execute it with pcall the lua state is still waiting for the remaining statement but if you are already in a lua state you load a string and that returns you a function so there is no direct way to know if you are ready to execute the input or not i.e. whether the input is a complete statement or incomplete. Any simple work arounds?

If that's the case, you may want to look at as well (it's under a permissive license.) Otherwise, you can look directly at the lua source code to see how it's implemented (in src/lua.c if memory serves.)
