Re: Parsing to byte code

["Matt Holmes" <kerion@...>]

Well, after checking out lua_loadfile/buffer in 4.1, I think perhaps my
question was misinterpreted.

What I want to do is this:

A script file path gets passed to my method. Said method opens the file,
does some pre-parsing that my engine does (special meta-data tags), then
strips those tags and prepares the actual Lua code for the interpreter. Once
it has the Lua code in this buffer, I want to be able to tell Lua "Okay,
parse this and turn it in to byte code, but don't execute it. Oh, and I need
the byte code back from you please". This would allow me to cache the
bytecode in memory, rather then keeping the source text hanging around. I
need to do this because on a fully populated MUD with hundreds of players
and thousands of objects floating around, having Lua reparse every script
file everytime an object is loaded is utterly wasteful. I already cache
script files in textual form, but I would much rather cache them as byte
code to save the interpretation step.
