Yes, sorry, I was a littlebid off-topic.
But you asked, if the stream-parsers are
deprecated.
And you also asked, if most people are using ocamllex/ocamlyacc.
So I thought it was for your interest too,
to hear such opinions about selecting ocamllex/ocamlyacc.

For later I will try the other parer-stuff too, but for now,
where I look to get some projects running, it's best to do it
such a "compatible" way.
So rapid development can be done in OCaml very fast. And when all
goes well, the software will be ported back to C, if not possible
to show the people that it's better to let it as it is (and in OCaml).

If this did not interest you, sorry.

Well ocampp4? The first time I hear from ocampp4.

Ah, ok. Fine. ;-)

Ah, ok. So then I decided the right way. :)

Sometimes it seems to mee, that people who are writing about
the stream-parsers on this list, would ´choose this because it's
good for doing hard parser stuff.
So I maybe misunderstood this.

As I planned (for a long time, but now started to lift up my ass and
start with it) to implement own languages (Domain Specific Languages),
so I need a tool for doing the lex-/parse-stuff.

I will start with simple things, but I'm shure it will be complex
short time later... :)

And as maybe said before, I'm happy to have OCaml on my side. :)

BTW: is there something like a converter from OCaml to C, so
that I can write OCaml-code but for people who wants it in C
it can be converted automatically?
(Well, they should install ocaml instead... but....)
