[Caml-list] RealWorld-Examples for OcamlLex/OcamlYacc?

[Caml-list] RealWorld-Examples for OcamlLex/OcamlYacc?

[Oliver Bandel]

Hello Hackers,

after pausing with OCaml and programming at all,
coming back to an interesting problem to solve,
I tried to solve it in C, with flex and yacc.

Even if find C nice, it was annoying how much
code to write... so it seems to be true, that
OCaml is a drug.

Back to it now, I ask the other addicts here for
real-world programs, that use ocamllex and ocamlyacc
and if available, a good tutorial.

The example in the Refman seems a littlebid confusing to me:
There is a function Parser.main called, but in the Refman there only
is a module Parsing, not a module Parser described.

And in the ocmallex/Ocamlyacc-chapter I didn't find something about
a call to Parser.main.

Or maybe I'm short-time blind, evry time, when I look into that manual?


Any help and hint is welcome... please help this OCaml-addict
programmer who I am now.


TIA,
   Oliver

May I remind you that each ocaml source file is a module, so if you
have a parser.mly it will produce a parser.ml, and so a Parser module?  

Then in the given example, the main rules is named "main", so the
Parser.main must be the call to the main rule of the parser your are
definning...

The OCaml compiler itself is a very good example.  Have a look at 
parsing/lexer.mll and parsing/parser.mly in the OCaml source 
distribution.  I learnt a lot from them.
