Subject: Proposal: replace ninja with samurai
From: "Drew DeVault" <sir@cmpwn.com>
Message-Id: <BYZDB5LH4OVY.9FDVF5I3J954@homura>

Ninja is a build tool which fills the same niche as Make, and samurai is
a third-party implementation on of Ninja.

https://github.com/ninja-build/ninja
https://github.com/michaelforney/samurai

samu is much simpler than ninja, clocking in at around ~3,000 lines of
C, compared to Ninja's ~20,000 lines of C++. samu also supports a
SAMUFLAGS environment variable which we can use to tune the -j flag in
abuild, similar to Make. Samurai is a drop-in replacement, but is not
bug-for-bug compatible with Ninja.

Ninja upstream has been hostile to appeals from distros and users alike
to add a similar environment variable. Their argument seems to boil down
to being proud to only support one environment variable, which can
change the format string their progress meter is printed with. Their
attitude is non-cooperative towards distros, and I would rather use an
implementation which plays more nicely with others.

I've been using samu as my daily driver for a few years now, and I've
yet to meet a project it couldn't compile. Its performance is also
comparable to ninja. A samurai package is available in community on edge
if you would like to try it for yourself.

I propose dropping the ninja package and adding provides=3Dreplaces=3Dninja
to the samurai package, as well as a symlink from /usr/bin/ninja to
/usr/bin/samu.
