Description (last modified by mkoeppe)

Currently we have to write:

sage: polymake("tropical::uniform_linear_space<Max>(3,2)")

or

sage: getattr(polymake, "tropical::uniform_linear_space<Max>")(3, 2)

or

sage: polymake.function_call("tropical::uniform_linear_space<Max>", [3, 2])

because the template brackets cannot become part of the Python function name, so the normal . syntax cannot work. (Also, but not the point of this ticket - #27736: Polymake: Turn polymake applications into objects with directories.)

Also,

    polymake("tropical::uniform_linear_space<Max>")(3,2)

does not work. It looks for an overloaded function without arguments, which fails:

    TypeError: no matching overloaded instance of Polymake::tropical::uniform_linear_space<Max>()

Also,

sage: polymake.call("tropical::uniform_linear_space<Max>", 3, 2)

does not work -- the undocumented and untested call method passes the args tuple to function_call, which expects lists instead of tuples.

  • Milestone sage-8.8 deleted

As the Sage-8.8 release milestone is pending, we should delete the sage-8.8 milestone for tickets that are not actively being worked on or that still require significant work to move forward. If you feel that this ticket should be included in the next Sage release at the soonest please set its milestone to the next release milestone (sage-8.9).

Moving some tickets to 9.2. This is not a promise that I will be working on them.
