Execute LUA-script one instruction at the time.
September 04, 2004 07:14 AM
Is it possible to gain external control over a script when you embed lua.
I would like to do something like this:
lua_State *l;
l = lua_open();
luaL_loadfile(l,"test.lua");
//... Register my functions.
while(statements_left(l))
{
lua_step(l);
}
I would also like to know if there is a way to set a memory limit for lua_State without having to alter the LUA source.

For single stepping, you can set a line-count-hook. This is primarily useful for debugging your program by single-stepping. If you want to execute part of a script, then stop and come back later and finish it, coroutines are a better bet. Read the manual for details on either.
In terms of setting a memory limit: If you want a hard limit like that, you do need to edit the source. Everything is gathered into lgc.c and lgc.h. It's pretty easy to follow.

Offtopic: is there some roadmap to the lua sources, or should I just go ahead and read them?

IIRC, there's a bit of a roadmap to the VM (which is one of the most complex parts) but that's about it, as far as I know. Jump on in.

I tried the lua_sethook function but I can't find a way of hooking statements. And if I were to use coroutines I would have to implement them myself in C since I don't want to enable them for the scripts I'm running.
I like Lua, but I'm not sure that it is the best thing to us for what I'm trying to do.
Do you know if there is a scripting language that can be easily embedded and execute individual statements?

Just set a linecount hook to execute every 1 line.
