#5502: implement ascii art output for Dynkin diagrams
---------------------------+------------------------------------------------
Reporter: AlexGhitza | Owner: mhansen
Type: enhancement | Status: new
Priority: major | Milestone: sage-combinat
Component: combinatorics | Keywords: dynkin diagram ascii art lie
---------------------------+------------------------------------------------
Changes (by bump):
* milestone: sage-3.4.2 => sage-combinat
Comment:
I uploaded trac_5502.patch for this. It applies to sage-3.4.1.rc2 and
there are no errors in {{{sage/combinat/rootsystems/*.py.}}}.
I have not tested it against the combinat patchseries because at the
moment hg qpush -a fails in sage-combinat.
After the patch, the {{{__repr__}}} method of {{{class DynkinDiagram}}}
returns ascii art for the classical Cartan Types.
A natural extension would be to give the extended Dynkin diagram for the
untwisted affine types.
