The problem is versioning. One of the goals of Pd-extended is to be
compatible with the same version of Pd-vanilla, i.e. Pd-extended
0.40.3 can run anything that Pd-vanilla 0.40.3 can. I imagine that
desiredata has a similar goal, but maybe not. The objects in 'extra'
are part of what Pd-vanilla 0.40.3 provides.
So if the objects in extra come with the 'puredata' package and are
put into the common /usr/lib/pd directory, then the 'pdextended' and
'desiredata' packages would use the versions that come with
'puredata'. So that means they would need to be removed from the
'pdextended' and 'desiredata' packages. That's not a big deal, I am
ok with that. But the problem is that if 'puredata' gets updated to
0.43 while 'pdextended' is still at 0.42, and 'puredata' puts the
'extra' externals into the shared directory. Then 'pdextended' can't
be 0.42 compatible anymore.
One idea is to package Pd vanilla's 'extra' separately, i.e. 'pd-
extra'. Then 'puredata' can Recommend 'pd-extra' and 'pdextended' can
Conflict with 'pd-extra' and I can make versioned packages for
'pdextended', ie 'pd-extra042'. Another is to have the extra folder
from 'puredata' in /usr/lib/puredata.
By the way, is anyone from pure:dyne listening? It would be great to
have some input from you.
