[Caml-list] Two questions about lex/yacc and lablgtk/gl

[Caml-list] Two questions about lex/yacc and lablgtk/gl

[Nicolas FRANCOIS]

Hi.

I'd like to create a 3D dynamic geometry application. I developped
DrGeoCaml a few years ago, but it's now quite old, and my Caml practice
is a bit rusty. So a few questions to start on the right tracks :

1) I'd like to create a parser, with the help of ocamllex/yacc, but
I don't find the help pages very instructive. Is there a good
tutorial like "Ocamllex for complete numbs" ?

2) I'd like to use lablgtk for the graphic interface, and lablgl for
the 3D visualization. It's mentionned in lablgtk documentation that
this can be done, but once again, i didn't find much help. Any clue ?

Thanks for any tip.

\bye

I don't know of any such tutorial, but you can also watch out for a lex  
tutorial (i.e. for C), because the matching algorithm is exactly the  
same. The syntax is of course different, but I guess this is the easier  
part, and extractable from the manual (or sample code).

Regarding ocamlyacc, consider to use Menhir instead. It includes a mode  
where grammar conflicts are explained by example, and in my experience  
this is the difficult part of developing a grammar. And it has macros,  
and other convenience features.

We can use LablGTK for OpenGL windowing with any OCaml-OpenGL bindings.
There are currently 3 OCaml-OpenGL bindings:

- LablGL (the older one) http://forge.ocamlcore.org/projects/lablgl/
- GLCaml (generated code) http://glcaml.sourceforge.net/
- glMLite () http://www.linux-nantes.org/%7Efmonnier/ocaml/GL/

As long as I know, if you want to write forward compatible OpenGL code in 
OCaml, you can only do so with glMLite.

If you need some help for LablGTK-OpenGL (any binding) or OpenGL in OCaml (any 
binding) just ask.

Thank you everyone for your kind help.

Clearly, everyone subscribes to both the mailing lists, so any will
do :-)

I'll contact you later for more help.

\bye

PS : The Ocamllex/yacc tutorials are great, but I can't get the pdf
versions.
