  • Status changed from new to needs_review

Implement default methods for (With)Realizations that use the realization provided by the method a_realization for computations:

  • AlgebrasWithBasis.ParentMethods.product is modified to use product_by_coercion if product_on_basis is not available
  • Magmas.Realizations added and Magmas.Realizations.ParentMethods.product_by_coercion uses self.a_realization()
  • CommutativeAdditiveMonoids.WithRealizations added and CommutativeAdditiveMonoids.WithRealizations.ParentMethods.zero returns self.a_realization().zero()
  • Monoids.WithRealizations added and Monoids.WithRealizations.ParentMethods.one returns self.a_realization().one()
  • Sets.WithRealizations.ParentMethods.inject_shorthands : injects any shorthands names for realizations provided in the _shorthands attribute
  • added _shorthand attribute to the example in sage.categories.example.with_realizations

And update examples/with_realizations.py accordingly.

100% doctest coverage for algebras_with_basis

comment:3 Changed 8 years ago by saliola

Mike pointed out that algebras_with_basis.py needed only 1 doctest to get 100% coverage, so this latest patch adds one.

Latest patch switches to using the class name for determining the default realization name (currently, the class name is taken and it is rendered lowercase for some reason; there was a FIXME suggesting this should not be lowercased).

comment:10 Changed 8 years ago by nthiery

For the record: I imported the latest version of the patches in the Sage-Combinat queue, and rebased my functorial construction patch on top of it.

Cheers,

Replying to saliola:

Latest patch switches to using the class name for determining the default realization name (currently, the class name is taken and it is rendered lowercase for some reason; there was a FIXME suggesting this should not be lowercased).

There was a question mark at the end of the FIXME; so this was to be discussed! Oh well, since it's merged in, I guess we can just consider the discussion as closed.
