Description Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2021-05-05 13:27:07 UTC
Please consider improving the visual sorting algorithm to detect numbers.  Right now python3_10 is being sorted before older versions:

[ebuild   R    ] dev-python/pyparsing-2.4.7-r1::gentoo  USE="-examples" PYTHON_TARGETS="pypy3 python3_10 python3_7 python3_8 python3_9" 0 KiB

Actually, radhermit came up with a better idea in pkgcore: to sort based on order in profiles/desc.

    emerge: Sort USE flags in output using combined alnum sort
    
    Sort USE flags in output by a combined sort that treats sequences
    of digits as numbers and sorts them numerically rather than lexically.
    As a result, python3_10 now sorts after python3_9.
    
    Ideally, we'd just respect the order from profiles/desc but this should
    work as an intermediate solution until we figure out how to implement
    that.
