Re: D support, not sure what to do

Hi list,

This is mainly directed at Russell, but I hope he and I are not the only one willing to build D code with SCons.
I have a pet project of mine[1], mainly to scratch 2 itches:
- learning D
- helping me with managing my time

I started using dub as the build system for it but started quickly spending a lot of time fighting with it to get it to do things I expected it to be able to do (installing stuff, integrating with system dependencies, handling translations, etc) instead of actually coding the thing. I even submitted patches.
Eventually, I acknowledge that dub  wasn't either quite there yet or simply that I was using the wrong wrench to nail that thing (?).
Anyway, what I ended up doing (which I must admit is pretty much what I always end up doing) was going with SCons which doesn't quite do what I want, but most of the time is halfway there because of its flexibility.
 I implemented a few wrappers and utilities around the D builders in SCons [2] (unit test builder,  ddoc builder, etc) and am now up to a point where I think they're worth sharing, at least with you guys.

I am willing to help with D support in SCons as I hope this would attract more people to both D and SCons (the best combo if you ask me), but I don't have much time, a situation many of you I'm sure are familiar with😉

I'm writing this on my phone while waiting for my kids to fall asleep, I'll try to elaborate a bit more tomorrow....
