Wanna find garbage tests in your #ElixirLang codebase?
I'm working on a Credo check that will flag any test that fails to exercise production code. Stuff like:
test "to_string works" do
assert to_string(:user) == "user"
end
(That's a real example I found in our ~20k test codebase!)

@nprofile…lgpc I have two:
1. “Let’s double-click on that.”
2. “Learnings” as a noun (we already have a noun for that… it’s a lesson!)

If I say “holy shit, people are mad about that blog post,” does everybody know which one I’m talking about?

One of y’all should go write #ElixirLang at Apple.

TIL that SmartRent forked the #ElixirLang Styler project to actually make it configurable. Quokka is the Credo-but-just-fix-it-for-me that I've wanted for 6 years of doing Elixir. 😍 😍 😍

Proposal for a new convention for referring to #ElixirLang functions when you absolutely can't be bothered to count its arity:
MyModule.my_fun/???

@nprofile…n5tq Hey, sorry to bug you… if you can approve this fix to CI, I can take care of the remaining open PRs on Geo. 😄

There's a remote code execution vulnerability in OTP. Update your #ElixirLang deployments to OTP 27.3.3, 26.2.5.11, or 25.3.2.20 ASAP.

64 GB of RAM. 16 CPU cores. Can't type in a comment box on a GitHub PR review in real time.
Maybe someday we'll have the computing resources for this...

My 8 year old has been really into making games in Scratch, and is thinking about moving to a text-based programming language to get past some of Scratch's limitations.
Any recommendations for simple Elixir-based games, or should I bite the bullet and do Python?

I have an unhealthy love of utterly unwieldy conference talk titles. They just amuse the hell out of me.
Current title I'm playing around with:
You Already Know What a Monad Is (Even If You Didn’t Know That You Know), and Why That Matters

2025-04-03 18:06:30 UTC

I missed it initially, but the call for proposals is out for ElixirConf US 2025.
I think I'm gonna submit a couple talks, one a followup to my lightning talk last year about the Result monad, and another about adversarial web scraping.

Likewise I tried adding a blocklist derivation of Inspect to `MyApp.Schema`:
defmodule MyApp.Schema do
defmacro __using__(opts) do
quote do
use Ecto.Schema
@derive {Inspect, except: [:password, :name]}
end
end
end
...but Inspect gets mad about unknown fields.
Any ideas?

2025-04-01 13:09:44 UTC

Okay #ElixirLang folks, I need your ideas...
I'd like to override the fallback Inspect protocol for all structs to redact certain sensitive keys. For instance, I'd like the backtrace of:
Enum.reduce(%User{password: "secret"}, fn _, _ -> :ok end)
...to redact "secret".
I'd really like to avoid relying on devs to remember to derive the Inspect protocol on every struct they create.
I tried to do:
defimpl Inspect, for: Map do
...
end
...but Elixir is displeased with me (inscrutable errors).

Hey, uh... apologies to everybody I've been less than responsive to, especially around open source stuff. My dad died unexpectedly at the beginning of March, and literally 8 hours later, my grandma went to the ICU for three brain bleeds. Family stuff has been A Lot™. 😬

Man, I feel this so much. I've invested a ton of time into GitHub Actions over the years, and the tight integration with GitHub makes it really hard to beat (imagine that). There are so many sharp corners, though, on seemingly simple things.

If you're writing tests for an Ecto schema module, consider using Ecto.Changeset.apply_action/2 (or its ! variant) rather than actually hitting the database.
It’ll return the struct as though it had hit the DB if and only if the changeset was valid.

Obviously this isn’t a huge optimization, but it’s nice to know about, and it can make a speed difference on a big enough test suite.
The biggest limitation is that it won’t run checks that only happen within the actual database, like foreign key checks.

@nprofile…dppm I do tell Siri she's utterly useless. 😆

I am impeccably polite when addressing an LLM. Some day, when our AI overlords take over, they're going to remember that and spare me.
