Instead of shipping KDE or KF5 as a whole with
each and every little game, it would be very
nice to have a means to redistributeably install
a meta-port like kde4-workspace (as discussed
in the before-mentioned parallel thread) which
then would include everything needed for properly
running any KDE4 application.
One would then have to ship only the meta-port
mdmv package and the several mdmg packages for
the whatever KDE4 application.
All these would - IDEALLY - have to be built in
such a way that they can coexist with an
existing MacPorts installation, I suppose. This
does not only mean that the PREFIX shouldn't
be /opt/local, but merely also that the
application's configuration data needs to be put
in
location(s) separate from the standard ones used
by a normal MacPorts install Think about
/Library/Launch(Agents|Daemons)
[~]/Library/Application Support
~/Library/Preferences/KDE
~/Library/Caches
~/.config
~/.(cache|config)
and possibly quite a few others.
Since this is even more complicated, for a start
I think, one would surely like to avoid such
a coinstallable approach. However, not having it
would make testing pretty hard (if not even
close to impossible), I am afraid.
I don't think there is any realistic way to do
'additive' installers (ie install a bunch of base
libraries with one installer and then install one
or more apps that use those libraries). I think
it would be all too common for the user to
install the base and one app at one time and
then, months or years later, install another app
only to find that it is broken due to base
upgrades in between.
Another wrinkle that occurred to me is that mdmg
installers sometimes need to be built with
non-default variants. For example, my standard
invocation for Myth is:
sudo port -f mpkg mythtv-pkg.27
+mariadb+mariadb55+python27+perl5_16+startupitem
I _have_ to specify
+mariadb+mariadb55+startupitem or the MythTV
package will be non-functional. The
+python27+perl5_16 ensures that I don't get
copies of other versions of perl and python--thus
reducing the size of the installer by about 20%
(which is still ~400 MB).
I have to use the -f flag to make the horrendous
hack in MacPort_daemondo succeed. I'm hoping a
GSOC student will figure out a clean fix for the
issue.
