Re: SLB vs LuaBind

[Jose Luis Hidalgo <joseluis.hidalgo@...>]

Mmm... Hi,

   Looks like it is pretty easy to add variable access, if you really
need it. I can try to add it to SLB...

About constructors SLB, supports just one constructor, but with any
kind or number of arguments:
.constructor() <- default
.constructor<int,int>() <- get's two ints

also, from lua, you have some methods to retrieve info from classes
SLB.type(...) -> returns a table with lots of info from the class,
methods, constructors, even comments

If you try SLB please, try the testing branch, which has a lot of
features added:

http://code.google.com/p/slb/source/browse/?r=testing#hg%253Fstate%253Dclosed

... So, let me think how to add the variable accessors, and write a
little example,...

Regards,
   JL.
