Examples of creating C++ library bindings

[Joel Reymont]

Are there any examples of creating C++ library bindings?

	Thanks, Joel

Is it what you're looking for ?

Mathias, thanks for the pointer. I'm looking for a reasonably small  
but idiomatic (is there such a thing with FFI?) example of C++  
bindings. I would like to know if I should I prefer classes or use  
modules, for example. Do I go with SWIG or do it manually?

	Thanks, Joel

I have done it few times, mostly just to see how it works. At the moment 
I'm writing a (hopefully) real usable binding to a c++ lib.
For big libs it's better (faster) to generate them but if you want some 
(small) part, you can do it yourself, it's much writing. I can send my 
code as an example and answer questions (no docu yet). It mirrors a c++ 
lib on the ocaml side, with working inheritance and overwritable virtual 
functions and event callbacks

cheers
 Michael

Unless you're willing to do some work on the SWIG OCaml generator you
should avoid it.  The code it generates doesn't compile.  Having said
that, if you *do* want to work on the SWIG OCaml generator it would be
a great service to the community!

I also thought about just taking the swig c++ parser and generating some 
similar binding as I now do by hand - would be interessting.

BTW, I have a vague recollection of somebody posting an announcement
of a C++ parser for ocaml recently.

Well, on the "Caml Humps", you should be able to find something. :)

In particular, I released a *simple* version of an OCaml binding for 
the PCRE pattern-matching library: "LablPCRE 1.0".  While simple, it 
is also non-trivial (it utilizes "custom" blocks with finalization).

As it happens, the package was originally class-based, and then was 
switched to a module orientation after "input" from the list. ;)

I also have a much larger binding for the Scintilla editing component 
("LablScintilla 0.9pre1"), but it *is* quite a bit larger, *and* 
interfaces with LablGTK (representing a much more interesting can of 
worms).. so it would be better to digest LablPCRE first.
