Scilab: Why not written in OCaml?

Scilab: Why not written in OCaml?

[Oliver Bandel]

Hello,


the program Scilab, a Matlab-clone,
written by INRIA, is written in C,
and since version 5.0 is using Java-Stuff for Plotting,
and this stuff is used in a way that it does not really
support Linux...


...why is that program not written with INRIA's
Ocaml?


Maybe rewriting it would make sense,
because Scilab seems not to be very stable.

...and from INRIA's view I would think: they have developed
OCaml, but do not use it for their own developments....
... strange, isn't it?

Ciao,
    Oliver

I think you don't quite realize how big an institute the INRIA is :

http://www.inria.fr/inria/enbref.en.html

Plus, there are a variety of other (domain-specific, mostly) languages
developed by INRIA teams, and anyway there's no reason to enforce the
use of OCaml in all INRIA projects. That would even be strongly
counter-productive, since I don't think you can find 2800 scientists
in the country (covering all IT fields) who know OCaml well enough. As
frustrating as it may seem, most teams are actually using mainstream
languages.

Cheers,

Stéphane L.

On the contrary, the bigger INRIA is the more valuable it would be for them to 
eat their own dog food. If OCaml had more users in INRIA it would garner more 
useful feedback and would be more likely to get funding.

Why not use Bigloo? It's a efficient scheme compiler, also developed at INRIA.

Just kidding,

Hi,

I looked at bigloo before I came to OCaml.

I decided against it.
Not only because of schem's ((((())))()(()()))))))-terror ;-)
but also (main reason) because of this:


"Bigloo produces C files. C code uses the C stack,
  so some programs can?t be properly tail recursive.
  Nevertheless all simple tail recursions are compiled
  without stack consumption."


This was not really inspiring confidence.
Even if I did not really know much about that topic tailrec-topic,
it seemed to be a basic feature, and other scheme implementations did  
not have such a limitation...
...then I had contact to Haskell and Ocaml and decided OCaml to be my  
favourite.

I never looked at bigloo again, but that quote above is from the  
bigloo-documentation that I just now downloaded to assure the point  
has not changed during the last years.

...yes, it's like MickeySoft running Linux- and BSD-servers... :-)
  ( they really do )

Hi,

There is probably a simple and yet very good reason scilab isn't
written in ocaml. Its predecessor was started in the 80s and scilab
itself was started in 90s[1], I guess that rules out ocaml and caml
which was only 5 years-old at that time. ;-)

Now that doesn't explain why it is moving to java instead of ocaml but
I think other messages in this thread already do. :)

Psilab is Ocaml (plus C and Fortran libraries):

Probably for the same reason than all Princeton university
programs are not written in SML/NJ (so I guess) ?

INRIA aren't using OCaml because SML/NJ sucks? ;-)

They're not?
