Expose IANA_TZDB_VERSION

[westy92]

Fixes #131. 🚀

[westy92]

I added a test, but I also verified I can use this locally when pointing cargo at my branch:

chrono-tz = { git = "https://github.com/westy92/chrono-tz.git", branch = "expose-tzdb-version" }

assert_eq!("2023c", chrono_tz::IANA_TZDB_VERSION);

We just have to remember to update this value when we bump the version.

I don't want something that's updated manually. There should be something in place to handle this for us. We're already doing codegen, so it seems like this shouldn't be too hard?

[westy92]

This is now fully detecting the version via codegen just like tz itself does - by using git describe (https://github.com/eggert/tz/blob/main/Makefile#L632).

@djc all PR comments have been addressed. 👍

I'm open to merging this at this point, but it would need to pass CI... Sorry this is taking so long!

[westy92]

This is passing locally on my Mac - I'm trying to track down why CI is failing. Could you please rerun the macOS build to see if it passes? It is getting canceled due to the other failure.

[djc]

I don't think I can rerun the macOS job only?

[westy92]

If you navigate to the job, you can re-run just one.

[djc]

it fails on macOS as well.

@djc CI is green 🎉

[westy92]

Done ✅

[djc]

Thanks for sticking with it! I'll see if I can get this published shortly.
