I am looking for a way to call my own C++ function automatically at the end of each line in a Lua script. The Lua SetHook function seems to do this:

However, the HOOK_MASKLINE function description has one giant caveat in its description:
(This event only happens while Lua is executing a Lua function.)
What problem do you see with this caveat? Is it that you would like to have your hook called after each line of code in a C function?
I am not sure what this means, but the hook doesn't seem to get called in the manner I expect.
How, then, *does* the hook seem to get called?
If I had a script like below, I would expect the hook to be called after executing each line:
local a = 1 --hook executed!
local b = a + 1 --hook executed!
b = b + 2 --hook executed!
Is the functionality I want supported in Lua?
Yes. This is what the line hook does (technically it's called *before* the line, but it's much the same). Could you post some code?
Cheers,
Geoff
