Hi! It looks like Microsoft is moving ( with its new operating system codename Longhorn) to completely managed code( see reports from their PDC). What does that mean for D? Will D compilers translate code to MSIL(microsoft intermediate language) to be excecuted by their virtual machine (CLR)? Albin |

Posted in reply to Albin Pucnik | "completely managed code" isn't true, but Longhorn clearly increases the focus on managed code even more. D has been designed as a "systems" language (a "replacement" for traditional C/C++). MSIL/CLR/.NET has been suggested before, but seems to be against the "systems" nature of D.

Posted in reply to Albin Pucnik | A managed version of D is probably doable with enough resources. His point I guess, is that managed code don't sound like it's any good for the efficiency necessary for a systems language. I haven't read anything about Longhorn yet, so I should probably not comment any further. But I can't let go; It would probably be excessively stupid by MS to drop support for their C API with 10+ years of legacy application code.

Probably the upper layers like the shell will be written in managed code. But I can't imagine that the low level stuff would not have have C APIs. |

Posted in reply to Lars Ivar Igesund | You should not underestimate the efficiency of C# and the CLR. Comparisons (in windows::developer network) show that it can be much more efficient than current c or C++ - depending on the quality of the libraries etc. Ch.

It does not seem that I can make an O/S using D... There's a OS kernel writen in D at http://www.geocities.com/one_mad_alien/dkernel.html Haven't tried it thought. |
