Nop. Bower isn't even packaged in Debian. Though I may try to do it
(when I'm done with other Mirantis stuff like packaging Fuel for Debian...).

I think that's a very good idea!

AWESOME ! :)
Then now, everyone is happy. Thank you.

The issue is that there's often not just a single path, but a full
directory structure to address. That is easily managed with a Debian
xstatic package, not sure how it would be with Bower.

What I'm not a fan of, is that we'll have external dependencies being
bumped all the time, with unexpected consequences. At least, with
xstatic packages, we control what's going on (though I understand the
overhead work problem).

By the way, I went into bower.io as I wanted to have a look. How do I
download a binary package for let's say jasmin? When searching, it just
links to github...

This would only work if upstream package directory structure is the same
as the one in the distribution. For historical reason, that's
unfortunately often not the case (sometimes because we want to keep
backward compatibility in the distro because of reverse dependencies),
and just changing the path wont make it work.

s/lib/share/

However, I'm almost sure that wont be enough to make it work. For
example, in Debian, we have /usr/share/javascript/angular.js, not just
/usr/share/javascript/angular. So django-bower would be searching on the
wrong path.

Maybe that's right for the OpenStack project, but that is a problem at
least for me, as I wont be constantly looking at Horizon dependencies,
just at the global-requirements.txt. So I'm afraid I may miss some new
stuff, and miss the deadline for the next release if I don't pay
attention to it. :(
Anyway, that's not so bad, I can try to adapt, but I just wanted to
raise my concern so that everyone knows about it.

Last thing: I'm currently a bit afraid of what will happen, as I don't
know the tools (bower and such). I wish I had a bit more time to test
them out, but I don't... :( So, I'm just raising my concerns even if
sometimes they may have no root, in the hope that we all find the best
solution that fits everyone. I hope the way I did in this thread is ok.

Cheers,

Thomas
