Hello,

Does anyone know if the Cyclone programming language is still being
developed? The "who is doing what" page says that someone is porting
Minix 3 to Cyclone. But I can't find almost any information about
Cyclone. Their website appears to be gone (http://
cyclone.thelanguage.org) and I saw a forum comment that the project
appears dead.

Does anyone know if Cyclone is alive and if Minix really is being
ported to Cyclone?

Daniel.

Hi,

I'm the one listed on the "who is doing what" page as working on Minix with
Cyclone.

The website http://cyclone.thelanguage.org is not gone. It just isn't
updated.
As far as I know they stopped development as well.

During my work, which has been slow, I had to make some programs to make up
for some lacking features, but all in all Cyclone can be used on Minix.

Porting Minix itself has been harder as the servers and drivers have some
requirements that Cyclone doesn't take into consideration (like talking to
tty directly instead of using the standard library calls).
I'm porting parts of Minix to test if it is feasable. A small driver is
already running and a larger part (some server) is planned.

If you have any questions, let me know.

Hi Joren,

I think you are doing some very interesting work. Since Minix aims to
be a highly reliable OS, the idea of writing it in Cyclone is
interesting. So sad though that they stopped development of Cyclone.

You said that server and drivers are hard to port. Do you have plans
to port the kernel too? I'm just curious.

Cheers,
Daniel.

Fortunately they did reach a version 1.0
Although it has some missing features, it does work

My plans currently don't incorporate the kernel. Although I have done some
work on in it at first.
It should be doable, but again is a little bit harder than servers and
drivers.

The toughest part will be to get Cyclone working without relying on mallocs
or writing a malloc for the kernel as Cyclone requires this.
I could disable the garbage collector Cyclone uses but then I still have to
watch the generated code to guarantee no mallocs are used.

Working on a bigger server, will give me better insight. And if I choose to
do the PM I might have to tackle some of these exact problems. So this will
be a good test.
