Replying to [comment:22 novoselt]:
> PALP, which is familiar to a number of people, does it as well as long
as the matrix fits the terminal. Then it switches to row vectors (the
switch, I think, is quite confusing).
Thats why PALP suddenly returns transposed matrices?? Is that anywhere
documented? I've observed this behavior but never figured out why PALP
does that. That is really a terrible design choice for a program so
technical that most people will want to parse its output.
> * I don't see what is the problem with having a function like
`sage.geometry.point_collection.default_representation` which allows you
switch between lists and matrices or anything else
The way I see it, the only difference between
{{{
sage.geometry.point_collection.default_representation = my_print_func
}}}
and
{{{
sage.geometry.cone.ConvexRationalPolyhedralCone._repr_ = my_print_func
}}}
is that I'll never discover the former, while the latter is the familiar
monkey-patching that you can do with any Python module. If you really want
to call it `default_representation` then I'm not totally opposed, but
nobody is going to use it because nobody is going to find out that its
there.
