Thanks to Mike Hearn, there's a comment about D under the JNode OS Posting:

Good going, Mike.  That's the way to spread the word! :-)

Would it be possible to write a OS / Kernel using D? I'm justing thinking about how to bootstrap this... does anybody has some ideas?

Absolutely, since no underlying VM is required.

Several weeks ago, I posted a link to one D based kernel I came across.  I don't believe it's on Digitalmars D language Links page so it's not easy to come across.  You have to search through the volumes of posts in this newsgroup to find it.

here it is:

http://www.geocities.com/one_mad_alien/dkernel.html

I haven't actually looked too much into this one, but the author seems to have a good base for an OS going (written using mostly D).

I think it would be great to have an OS with integrated garbage collection.  And D would be a great language to program it in.

Hi, I had a look but didn't found much infos. I'm going to write the author of it.

I think so too. Maybe one day we have a dinux. ;-)

Yes, there didn't seem to much information detailing the internals.  The author used to frequent this list, but I haven't seen him on in awhile.

LOL!  Yeah, that would be great.  Considering what the Linux kernal code looks like, D could provide a huge improvement in both coding style and power.  I can't stand all those preprocessor macro definitons and pragmas in the C source.  It makes for difficult reading.  I don't know if D can accomplish the same things without the preprocessor stuff of C, but I sure hope so.  I would REALLY like to see a successful operating system coded in D.

We are actually looking into the possible uses of D in Embedded systems where there may be no OS at ALL! It's all preliminary stuff at this point done - Whenever we get a chance. The biggest hindrance is the lack of support for CPUs other than x86 but that at least gets us a good R&D starting place to prove the concept.

I've been secretly dreaming of D backends for ARM and PowerPC.

I tried to mail him, but the address bounced. So, bad luck. I'm going to make my own way thru it than.

IMO with the features of D a nice designed kernel could be made. Maintenance, flexibility etc. everything should become more structured and clear. Walter, than we only need support for more platforms ;-). But I'm sure, you are faster than the kernel stuff...

I don't see why it shouldn't be possible. The hardest part will be boot-strapping the complete thing. I have to do some research for this and see if I can get a diskimage to boot under VMWare.

My examination of the linux kernel source was a source of inspiration for many D features <g>.
