So some questions arise:
1. Good idea or not?
2. Really? Could be viewed as bad mojo messing about one step too
far.
3. If OK, should it be static? ie the list of what gets imported and
handles what dealt with by a table lookup in Kamaelia/__init__.py ?
4. Or should it go OK, I was imported here, I'll rummage around in all
my
subdirectories, in this overall order
5. Do 3, then 4, if the name wasn't found in 3.
6. The other way round ?
7. Do we allow extra search paths for the case of 4 ? (think sys.path
for
modules)
8. How about allowing extra lookup tables to be added in the case of 3?
9. lots more possibilities.
I can see it would be much less verbose and that is a *good* thing! If
nothing else, from writing examples in documentation, where brevity is
highly desireable, adding all those import statements can be tedious and
ugly.
I would also worry about the situation where two or more components share
the same (leaf) name. Eg:
Kamaelia.Chassis.Pipeline
Kamaelia.Experimental.Chassis.Pipeline
There are also other components which, although they do not clash now,
look likely to later, eg:
Kamaelia.Audio.Codec.PyMedia.Decoder.Decoder
I suppose I'm asking, will someone's code break X months/years later when
more components are added to teh repository with the same name? This
concern therefore makes me worry this could be a short term gain which
causes future difficulties.
But maybe this is still a good idea and the solution is to develop a
stricter component naming policy? (and retrospectively rename existing
components to fit it)
Another perspective: If one of the problems this is trying to solve is
disagreement over where a component should be located in the hierarchy;
this could be solved by symlinking - ie. let the component be in both
places in the hierarchy where it is believed to make sense.
However, I guess this could end up being highly confusing! I can see it
would make sense if you consider the hierarchy as a hierarchical
classification scheme, rather than a packaging/encapulsation thing - eg.
more like categories on Ebay than packages in java.
