Elixir 1.19 is a banger! Honestly I'm so pleased with the direction that #ElixirLang is going. My programs just get faster and more correct every time. I just know that we're in good hands. Thank you to everyone on the team for your hard work!

FWIW, I almost never ask it to correct itself. Usually I start again, giving more information (or by updating my rules file), and then if it doesn't work, I just do it myself.

It feels like once it goes in the wrong path, it is very hard to "right" it.

One common pitfall when using lists in #LiveView is that they are not change-tracked. We might have something to improve that situation in an upcoming update! #MyElixirStatus #Phoenix #ElixirLang

A HEEx template:

~H"""
<ul>
<li :for={%{id: id, name: name} <- @items} :key={@id}>
Count: <span>{@count}</span>,
item: {name}
</li>
</ul>
"""

Notice the special `:key` attribute.

Just to confirm, it is all working as expected. It compiles on Erlang/OTP 27, but not on Erlang/OTP 28. It can't really work on Erlang/OTP 28 so I appreciate you going ahead and submitting PRs for those projects.

I have been busy doing too much community and ecosystem stuff to be a good prospector and salesman. If you think I could be helpful to your business, holler. We do big picture consulting on Elixir projects and their teams as well as hands on keyboard work.

Both algebra and reflection. For example, every binary has to be traversed twice, one to figure out to print it as a binary/string and another for the algebra document. Similar for maps deciding between keywords or => and so on.

That code will always fail on Erlang/OTP 28, so we added an earlier warning, but we should probably have gated it around a OTP_RELEASE check. I will do it now.

Btw, don't expect me to check bsky/twitter, this would have been seen earlier on official language channels. :)

I can confirm it is expensive, it traverses data structures, reflecting on them, then it builds an algebra document, and then it figures out the best way to format them. Although there may be some low hanging fruits somewhere.

As we're getting ready for the first release candidate of #Phoenix #LiveView 1.1, I want to write about some of the new features and improvements we've been working on. A thread!

Thank you! I wanted to post it here but unfortunately there is a 2 minutes limit on videos (and I didn't want to go through the hassle of uploading it somewhere else either).

Cool <3 We also have a Discord server on the website in case you want to join us and chat. There is a #rails channel!

After discussing it for a bit, I am thinking a "get_package_location" should be enough, as it can then use the regular shell commands to interact with that directory. Can you try that instead?

José Valim @josevalim.bsky.social · Apr 30

Sweet! Would you be willing to send some PRs? I have to discuss with the team but I can say for sure the built-in get_source_location should be able to deal with gems Then next we need to find out a way to read them (it works in Elixir because packages are installed within the project root)

Introducing Tidewave: tidewave.ai

While working on our web apps, we run code, query the database, read logs, search docs… but our AI tools are limited to reading code.

Tidewave closes this gap by introducing Runtime Intelligence, for Phoenix and Rails. More coming soon, check out the website!

#elixir community!

I’m trying to write a blog post and need some sources/data.

Could you please run "mix test" on one or more of your @elixir-lang.org codebases and report results?

I’m looking for:

1. # of tests
2. # of async tests
3. Total time sync
4. Total time async

Wow, LiveDebugger is amaaaaaazing.

It's a dev-only package that adds a little blue "bug" button in the bottom right of the screen to open a debugging dashboard. From that dashboard, you can inspect all the LiveViews running on your local server. By "inspect," I mean do things like:
