I wanted to use AppVeyor to add Windows CI to some of my D projects, but
when I tried the appveyor.yml config on the DWiki[1], I found it needed
some work.
So after quite a bit of tinkering (and throwing semi-random bits at the
wall to see what would work), I finally got it running properly in my
project: including support for older/newer versions of DMD/LDC in both
32/64-bit.
Then, I merged in some improvements DUB had made, plus laid some
groundwork for download mirrors (just needs URLs now), and pushed it up
as a project on GitHub for all to steal:
https://github.com/Abscissa/AppVeyor-D
One nice thing about this (compared to the DWiki page) is that its
actually being tested by AppVeyor itself. Plus, it now has full GitHub
Issues/PR support for managing enhancement/submissions/discussion, all
in one central place.
