Julien, Personally, I would be able to use the module you are proposing to accumulate arbitrarily-named measures. I can not think of a use case for division, but it would be nice for completion. I have made my own library that implements a small part of what you propose [1]. I was looking through the pstats.py [2] source code; and I thought it could benefit from vector operations. I have seen other code that collect measures have the same redundant pattern. Maybe some fancy regex can identify other += code sequences that would benefit. If you make a module, and show how it can simplify pstats.py, maybe you have a winner? [1] "vector" addition? - https://github.com/klahnakoski/mo-dots/blob/dev/tests/test_dot.py#L610 [2] pstats.py source code - https://github.com/python/cpython/blob/3.7/Lib/pstats.py#L156 On 2018-10-30 11:31, julien tayon wrote:
Hello :)
the idea is described here: http://jul.github.io/cv/pres.html#printable
Summary of the idea :
Take a linear algebrae book, and implements all the rules as a TDD. https://github.com/jul/archery/blob/master/consistent_algebrae.py
make it works based on abstract base class and sets of Mixins. https://archery.readthedocs.io/en/latest/
And see if we can make cos/__abs__/dot and if it gives naively the intended results ? (spoiler: yes)
Making it work with dict, and "other" dictionary like counter by using ineritance https://archery.readthedocs.io/en/latest/#advanced-usage
My idea is : wouldn't it be nice if we introduced geometries as sets of mixins for objects ? (Hilbertian algebrae could be nice too, and we could make MutableMapping behave like bra/kets).
So I was proposing a soft discussion on : could we agree that it would be nice to consider operation overloading as a whole set of behaviours that could profit from being consistent in a categorized way ? (like the + of [] could be the + of "RecordAlgebrae") Meaning we could define sets of "expected behaviour consistent interaction between operators" as we defined the abc and call them algebrae?
I offer the LinearAlgebrae Mixins as a POC, and was thinking of creating a unittest to qualify if an object is following the rules of linear algebrae.
What are your opinions ? I don't actually see a lot of use case except it was funny to build. But maybe it can be of use.
Cordialement
