Bonfire Expeditions - Collaborating to Release Version 1.0

Releasing the stable 1.0 version of the Bonfire federated social network requires collaboration with the communities, hackers, tinkerers, and sysadmins who plan to use it.

The first released candidate of LiveView 1.0 is out!

📘📘📘 New post: 10 @elixir gotchas!

It's a great language, but some behavior can be unintuitive, confusing and in the worst case lead to bugs. In this post I wanna help clear some of them up!

Elixir is a dynamically-typed functional language running on the Erlang Virtual Machine, designed for building scalable and maintainable ...

Published: Tail-Recursive & Body-Recursive Function Performance Across Elixir & BEAM versions – what’s the impact of the JIT?

Watch me go through @elixir and erlang versions from 1.6 @ OTP 21 up to 1.16 @ OTP 26 and marvel at our performance gains.

at https://hexdocs.pm/open_api_spex/3.2.0/readme.html there's a definition of a module User

defmodule MyApp.Schemas do
  alias OpenApiSpex.Schema

  defmodule User do
    @behaviour OpenApiSpex.Schema
    @derive [Jason.Encoder]
    @schema %Schema{
      title: "User",
      description: "A user of the app",
      type: :object,
      properties: %{
        id: %Schema{type: :integer, description: "User ID"},
        name:  %Schema{type: :string, description: "User name"},
        email: %Schema{type: :string, description: "Email address", format: :email},
        inserted_at: %Schema{type: :string, description: "Creation timestamp", format: :datetime},
        updated_at: %Schema{type: :string, description: "Update timestamp", format: :datetime}
      },
      required: [:name, :email],
      example: %{
        "id" => 123,
        "name" => "Joe",
        "email" => "joe@gmail.com"
      }
      "x-struct": __MODULE__
    }
    def schema, do: @schema
    defstruct Map.keys(@schema.properties)
  end

In order to avoid re-describing it like that for Open API Specs whilst having already done so for Ecto, is it possible to combine the two definitions in a single module somehow? That is, my Ecto schema User would serve its purpose for Open API Specs too. With some required tweaks.

And if I do combine them, won't this mess up with the methods of the 2 modules and other things?

Djot is a markdown alternative, created by John MacFarlane, creator of Pandoc and spec author of CommonMark. It aims to fix many of the little issues Markdown has, and does a pretty good job of it, imo.

In a third-party project, in the models, I've encountered functions like this:

  def changeset(model \\ %__MODULE__{}, params) do
    model
    |> cast(params, @required_fields ++ @optional_fields)
    |> validate_required(@required_fields)
  end

How can a function have a default argument which is both a) first and b) followed by a mandatory one?

What's interesting, they work properly.

Elixir For Cynical Curmudgeons

#elixir @elixir

I was wondering if there were any BDD/TDD projects or tutorials that anyone could recommend?

I'm currently learning elixir and when I was learning rust, I really enjoyed a tutorial called pngme. It has test cases and a specification but left you to implement everything else. Link to pngme: https://picklenerd.github.io/pngme_book/introduction.html

Does anyone know of any similar projects but for elixir?

Thanks in advance
