New description:
Dear All,
I have just pushed a patch to the combinat server which:
* deprecates ''r_core'', ''r_quotient'' (and ''k_core'') in favour of
''core'' and ''quotient'', respectively. I also made ''core'' return a
partition rather than a list.
* rewrites the Partition() calling function to use keywords rather
than named arguments. In the process I deprecated the
''core_and_quotient'' argument replacing it with
''Partition(core=?,quotient=?)''.
* deprecated ''partition_sign'' in favour of ''sign'' and replaced the
previous call to gap with plus or minus one as required.
Almost all of the changes are to partition.py, however, the patch affects
the following four files as they all called ''r_core'' or ''r_quotient'':
- sage/combinat/ktableau.py
- sage/combinat/partition.py
- sage/combinat/ribbon_tableau.py
- sage/combinat/skew_partition.py
Not all of the doc tests pass, however, the problems seem to be caused
elsewhere -- please let me know if I am wrong!
Andrew
