Unitful.jl VS uom

Julia's Unitful package is one of my favorites. https://github.com/PainterQubits/Unitful.jl

Tangentially related, LaTeX's siunitx package makes typesetting units a joy. https://ctan.org/pkg/siunitx

Not sure why you think more units is more powerful. Defining specific units is seldom the difficult part of dealing with units in code. I'd say that just looking at the tests for Unitful (excluding the separate tests for dates) to the tests of Similitude that there seems to be a lot more functionality in Unitful. What are the advantages of these alternate packages? And I do not think focusing on "more powerful" is too useful unless qualified appropriately.

It's really two separate problems but they kinda interact.

Unitful quantities with heterogeneous units don't have a `zero` function that works correctly, which gets in the way inside numerical routines. [0] There are other places where 0 or 1 is added, which is an error for quantities but not for plain real numbers. [1]

Zygote doesn't handle mutating arrays. [2]

Julia has the Unitful package [1], which does a decent job. It's quite ergonomic, and Julia's design helps with making existing code/libraries play nicely with Unitful-encoded units/values.

I've seen a few before, and a quick search yielded a bunch for me, right off the bat. By no means exhaustive:

Julia: https://github.com/PainterQubits/Unitful.jl

Python: https://pint.readthedocs.io/en/0.6/

C++: https://github.com/nholthaus/units

etc.

And yes, it has always struck me as strange that date/time/calendar libraries are standard as canonical libraries shipped with language distributions, but units are not.

uom (type-safe zero-cost dimensional analysis) v0.35.0 got released today!

It happened! v0.34.0 (crates.io) has been released.

My hope is to release uom (type-safe zero-cost dimensional analysis) v0.34.0 this week. There have been a huge number of new quantities and units added since v0.33.0.

I have been reviewing lots of PRs recently submitted to add many new units and quantities to uom (type-safe zero-cost dimensional analysis).

I reviewed some PRs to add new units to uom (type-safe zero-cost dimensional analysis) yesterday and am really hoping to make progress on logarithmic units this week. no_std support is slowing down the later.

Working on a PR to uom (type-safe zero-cost dimensional analysis) to support logarithmic units.

A great type system enables things like unit preserving calculations and Formal Methods.

Is it the error messages, or other parts of uom that make it unwieldy to use? Feedback welcome here or as a new issue.

I'm working through reviewing the open PRs for uom (type-safe zero-cost dimensional analysis).
