C++ class derivation in Lua
Hajo:
8MB! That looks massive.
When I did it, I decided for a more procedural notation style.
There were objects, but the notation was not
Code:
object_variable:method_name(parameter_list)
but
Code:
method_name(object_variable, parameter_list)
That seemed easier to create bindings for, and worked about as well. But Lua is a nice and efficient scripting language. I liked it much.

Thanks for taking the time to write this.

I mean, having 8MB of extra sources in my project (and thus inflating my executable size) isn't something I enjoy
It's that huge? :o 8MB of source code sounds... hard to believe, to be honest.

Have you considered using code versioning software with a (free) online repository? I personally use Mercurial (a distributed CVS) with a repository at assembla.com, and it works like a charm for alternating between working at home and on the road (erm, train). I can even hack on something while riding on the train, push the changeset onto my USB stick, and commit it into my main repository when I'm home. It's incredibly useful.
Besides all the other advantages you get from using a versioning system: incremental backups, an automatic development log via commit messages, tagging of release versions... I wouldn't want to live without it anymore.
Maybe, if some people are interested, I could write a tutorial on using these things since we now have this shiny new Tutorials section? I've found that many (especially amateur) developers are a bit scared of using such a system, but it's really not that complicated and a huge productivity boost.

That's a very nice tip! I think calling class methods isn't too hard, just a matter of pushing the class to the stack, probably figuring out the method name from the metatable, and then executing it as you'd call a normal function.
How'd you do the class definition without luabind?

Yeah, luabind uses the boost library, which has... Needless to day, a crapload of stuff. I could probably strip things down, but the broken-dependency battle is not something high on my priority list. :D

muku, I would definitely like to see that. I just started using bazaar w/ launchpad and really like it, but it took me a long time to figure it out/get it working right. There seems to be a lack of really basic tutorials on this kind of stuff, it's all advanced or very minimal information.

Ditto. though I should be able to figure it out myself, it's looking like I'm never going to get around to getting into the swing of versioning without external influence.
