Hello! I really enjoy D and some brilliant concepts in the
language, like scope(exit) for example. But what I dislike about
D is the druntime, where each single function depends on 100
other functions. I'd like to be able to develop system level code
in D (like windows drivers or linux kernel modules or do osdev),
but I can not do it, as D is very dependent on the druntime. It
would be great if D would have the same "pay for what you use"
way, as C/C++ do. So I'd like to ask several questions:
1) Is it possible to fully disable exceptions? Generally I tend
not to use exceptions in C++ as well, as exception path may take
a whole lot of a time. Also returning error codes or using
something like Expected<T> is more readable in most cases.
Obviously I'm not going to use exceptions in my code, and I won't
be linking with code that throws/catches exceptions.
2) Is it possible to fully disable runtime type information? I
understand that being able to get different information about
object type in the runtime may be very useful, but I've never
used it. However D compilers do generate RTTI-tables no matter
what with all class names, module names and etc.
3) Is it possible to fully disable garbage collection? Sometimes
having GC is a good thing, but I'd rather do manual memory
management or use automatic reference counting instead.
4) What compiler is better to use when I want to compile and run
D on "bare bones" (running code without operating system)? Is it
DMD? Or is it LDC? Or GDC?
5) Does anyone try to make a tiny druntime library? Did it work
out well for you? And can I have a look at it?
PS I know that these kind of questions come out in the D
community from time to time, but there's a lot of things I'd like
to discuss on this subject, so I decided to make a new thread...
sorry...
