Missing unit tests

10

I had to speed up refactoring, design, and implementation of the V2 design, and because of it plenty of unit tests are missing now. Any help would be appreciated. Here...

Do we really need ASCII-only text output?

12

Besides the Unicode text output mp-units provides the ability to [output ASCI-only text](https://mpusz.github.io/mp-units/2.2/users_guide/framework_basics/text_output/#unit-symbol-formatting) as well. Standardizing such ASCII-only text output will be hard as ISO and SI standards do not...

test: test_package now is tested also with C++20 modules

Gated by the following issues: - [x] https://gitlab.kitware.com/cmake/cmake/-/issues/25568 - [x] https://gitlab.kitware.com/cmake/cmake/-/issues/25909 - [ ] https://gitlab.kitware.com/cmake/cmake/-/issues/25916

Text input support is progressing through WG21 (https://wg21.link/p1729). A reference implementation can be found on a dev branch here: https://github.com/eliaskosunen/scnlib/tree/dev. This branch is still not provided in Conan: https://conan.io/center/recipes/scnlib.

Bikeshedding `force_in(Unit)`

10

As we discussed before, the spelling of `distance.force_in(si::metre)` may be confusing. Also, the C++ standard does not use "force" word anywhere to force a conversion. AU library is using `coerse_in(Unit)`...

docs: "API Reference" support added

5

This is the framework to present API reference. We can't proceed with this until the initial version of the API Reference HTML is prepared.

`quantity_point_traits` require `to_numerical_value` and `from_numerical_value` member functions. `quantity_point_like_traits` require `to_quantity` and `from_quantity`. This is consistent with the `quantity_point` and `std::chrono::time_point` design but is inconsistent with `quantity_point_traits` and may make it...

Add support for `zero`

`zero` is really useful, as described here: https://aurora-opensource.github.io/au/main/discussion/concepts/zero.

Measurement in IAU

Improve and productize a `measurement` class and use it in the definition of the IAU system based on https://web.archive.org/web/20131110215339/http://asa.usno.navy.mil/static/files/2014/Astronomical_Constants_2014.pdf.
