[SciPy-Dev] Custom __repr__?

[Pamphile Roy]

Thanks for your inputs Robert.

> Because these would involve extra dependencies (either matplotlib or some JavaScript), I would recommend starting with implementing these outside of scipy. You can register formatters for objects without modifying the objects themselves.

We already have a soft dependency on matplotlib in spatial for instance with a few helper functions (https://scipy.github.io/devdocs/reference/spatial.html#plotting-helpers <https://scipy.github.io/devdocs/reference/spatial.html#plotting-helpers>).
It would be the same here, something completely optional. Plus here the functions are private and don’t conflict with Python’s internals.

Nice examples, this is exactly this I had in mind.

Well, this registration outside is quite complicated IMO… Personally, I think I would even prefer to mock the underlying object and add the _repr_xxx I want…


Cheers,
Pamphile
