I'm thinking about inviting you to dlang-community then. Do you think you can fix at least the stupid stuff we have to do right know (install python 3 while it's already setup). Again today i have to do this:

    https://github.com/dlang-community/tinyendian/pull/18/files

Which is awfully slow. Most of the time is spent on setup python 3.6.3, which is not correct. CI tests for this product should not spend more than 30 secs. Now they raise to 4 minutes.

The problem right now is that i handle this while i should not. I have zero python+its ecosystem knowledge, i just use "dub" "make" or my own exotic way of building, so the fix has chances to be be stupid.

Just 3 minutes to install a python version at Travis, that will work to use Meson

    https://travis-ci.org/dlang-community/tinyendian/jobs/466966513#L122

That's **silly**.

What's even more silly is building Python manually first, then doing `homebrew update` (taking 290 secs!) before brewing ninja and Python again (the latter not working). If you just need homebrew for Ninja, then do yourself a favor and download the prebuilt https://github.com/ninja-build/ninja/releases/download/v1.8.2/ninja-mac.zip, that's what we do for LDC CI too. This `homebrew update` is ridiculous, at least for Travis.

That's fine by me. I may not be as active as I would wish at times so if that happens just give me a mention or send me an email.

Regarding your issue, it seems that meson 0.29.0 is available in xenial's repo so that might be worth installing directly. To avoid installing python each CI run, you might want to cache it[1]. That should speed up the CI quite a bit.

I didn't know that meson 0.29 is available on their xenial-based VMs but i was adviced yesterday to use xenial because it has python 3.5 which is good enough for meson. This is what i did, everywhere([1],[2],...), so everything is fine now.

By the way meson 0.29 is probably not capable of building D. This looks like a very old release.

At Fedora we use meson to build these projects. So yes it is useful
December 17, 2018
Debian uses meson to build things D as well and it appears to fit elegantly with their package creation tools, related work is already in place. Fedora it appears uses meson too. My understanding use of meson integrates with the rest of Debian package creation system and more or less automates the process... anything to make use of meson more straightforward makes the packaging and distribution of D tools, libraries and applications more likely, and should be positive with regard to the adoption of things D within Linux infrastructure (Debian + its many derivatives and Red Hat / Fedora). Reiteration of previous post. More with meson (and to assist its use with things D) please, not less.

(reiteration of earlier posts:)

Sorry for the super late reply! I have been really busy with the holidays.

At the time I didn't realize meson 0.29 was **that** outdated. If we cache the package contents' meson doesn't need to be installed on each CI run.

I'll try to open some pull requests with this hopefully working.
