Hi speps,

I judged that the typical person using this software would prefer to use
the vcs version.  I don't mind if the stable packages are not deleted
but don't want to confuse people and want to make it easy for them to
install the currently maintained -bzr versions.

The effort you have made is admired and appreciated.

I'll stick to the vcs versions just because I don't have time to
maintain two sets.  If someone does adopt the stable ones then we can
collaborate.

There is a difficulty with keeping the stable versions though; How do I
make it easy for users to build and install the set of -bzr packages,
rather than a mixture of -bzr and stable ones?

There are two issues.

1) the groups() variable is not used:

I envisioned being able to make use of the groups() variable by having
groups=('fenics-bzr') in all the -bzr PKGBUILDs and doing something
similar to:

$ pacman -S fenics-bzr
or, for stable versions:
$ pacman -S fenics

which works for packages controlled by pacman (and this is how I use it,
via local repos) but not for the AUR because the groups() thing isn't
accessible to AUR clients [fn:1].

2) the AUR client I use (cower) doesn't recognise dependencies are
satisfied on with the same action

The way things are now, in (e.g) ffc-bzr PKGBUILD there is:

depends=(... 'ufl' ...)

and in ufl-bzr :

provides=('ufl')
conflicts=('ufl')

so that if the user wants the stable versions of most of the fenics
packages but the vcs version of ufl, then they can install it and still
satisfy the dependencies.

However if I try:

$ cower -dd fiat-bzr ufc-bzr ufl-bzr ffc-bzr

it will download the stable PKGBUILDs for ufc and ufl to satisfy the
dependency in ffc-bzr, but I wanted the the -bzr versions.  I have
raised on Issue on cower's github [fn:2].

I am new to this list and maybe you have already discussed making
groups() accessible to AUR clients.  Perhaps an alternative AUR client
is better at calculating dependencies.  Am I doing it wrong?
