this PR introduces a new kind of file, `all__sagemath_categories.py`, Not, it's not a new kind of file. These files have been around since Sage 9.6 (https://github.com/sagemath/sage/issues/29865). The main purpose of these files is to define the global environment for doctesting, as documented in https://doc.sagemath.org/html/en/developer/doctesting.html#options-for-testing-in-virtual-environments For example, I see that PowerSeriesRing is imported, but LazyPowerSeriesRing is not. I don't understand the difference. The file pkgs/sagemath-categories/MANIFEST.in.m4 defines which modules are shipped by the distribution package *sagemath-categories.* The following lines there make the PowerSeriesRing available. > include sage/rings/power_series_mpoly.p* > include sage/rings/power_series_poly.p* > include sage/rings/power_series_ring_element.p* > include sage/rings/power_series_ring.p* The modules defining LazyPowerSeriesRing are not included. This distinction is then reflected in the all__sagemath_categories.py file as well: Can't import from a module that is not shipped. I thought that they were about the distribution packages, because that's what's mentioned in the top lines. That's right! "all__sagemath_categories.py" defines the global environment for testing the distribution package *sagemath-categories*. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
