PhoenixTest v.0.5.0 is out! 🥳
Lots of changes. My favorite: experimental assertion `timeout` option that waits for async operations (and handles redirects).
Less visible work (but sooo valuable) -- work to allow for a playwright driver. 🤯 (huge thanks to @ftes.de 🙌)
👉 hexdocs.pm/phoenix_test...

From upcoming @elixir-lang.org 1.18
> For example, you can invoke IEx.configure(auto_reload: true) and IEx will automatically reload modules changed elsewhere, either by a separate terminal or your IDE.
This is beautiful! 😍

The first barebones version of a Playwright driver for PhoenixTest:

Give it a drive, run your feature tests in a browser.
And please let me know what doesn't work.
I'm very grateful for any feedback 🙏

AoC Day 8. Lesson the day is to carefully read the instructions. I completely misunderstood the rules and while the logic was correct, what to count was not and I tried adding way too much caching for no reason. Over complicated things.

AoC Day 5. Lesson learned with this one is that the std library is good and I don’t need to solve everything with recursive functions. It was getting too complex and when it came to sorting, I got lost. Rewrote with lists:map and lists:sort and it all worked out

AoC Day 4. I don’t think I did this efficiently. Also intended to use persistent_term to store the grid and spawn processes to handle checking horizontal, vertical and the two diagonals concurrently, but things have come up.
