For anyone interested, I'm implementing everything in this branch
of my fork.
https://github.com/gdelazzari/dub/tree/colored-output
Seems like I managed to cleanly substitute the logging module
with a brand new one :P actually it's most copy-paste with
changes to allow colored output, but yeah. I also "imported"
d-colorize (by copying all its file in Dub's codebase - to avoid
having a Dub package dependency on Dub itself).
This is the relevant part (the new logging module) if anyone
wants to contribute with feedback or enhancements, since is some
of the first D code I'm writing. It's still missing the no-TTY
detection, but it's coming.
