Changelog

Enhancements

• Quick documentation (F1/Ctrl+Q)
• Run Icons in gutter next to ExUnit tests. The icon changes to the state of the test: green for passing and red for failing.

Bug Fixes

• Fix Unchecking Show Method Separator still showing on @doc and @spec.

  Previously, unchecking Show Method Separator would still show the method separator if it was the module attributes (such as @doc and @spec) associated with the call definition (def, defp, defmacro, or defmacrop) and only disabled the ones directly above the call definition. This is fixed by checking if method separators are enabled in getLineMarkerInfo(PsiElement) instead of the specialized getLineMarkerInfo(Call), so that the check happens for both module attributes and call definitions.

• Remove “Unresolved module attribute” error annotation because module attributes cannot be resolved through use yet, so current annotation is a false positive in those cases.
• Use SimpleTemplateLanguageFormattingModelBuilder for EEx files, so that the TemplateDataLanguage (i.e. html when the extension is .html.eex) formatter is used instead of the Elixir formatter.

In episode 7 of Thinking Elixir, We talk with Miguel Palhaus about lessons learned while working with background jobs in production systems. He shares some tips he’s learned through experience. We share other mistakes made and what we learn from them. We cover background job options, choosing tech based on the team you have, IEx tips to remind yourself you’re on production, and much more!

Returning a tagged tuple {:ok, result} | {:error, reason} is the de facto practice to handle errors in Elixir, but that may not be enough for all situations and this article will explore how to leverage Exceptions to enrich errors and the benefits of doing so.

Check out this excerpt from the upcoming Book Club episode with Saša Jurić and Erik Schön where they explore whether Elixir could be the right tool for your job. In the interview, Erik Schön, managing director at Nordic, also explores key benefits and practices with Elixir, a functional language with over 20k commits on Git Hub. The upcoming interview is based on Saša’s book Elixir in Action. https://gotopia.tech/bookclub/episodes/how-to-start-with-the-elixir-programming-language

We have been building a platform where using LiveView made a lot of sense, since we wanted some of our features to use an interface that could be updated in real-time. For example, we wanted administrators of the platform to be able to see, on a map, the sightings that the users of the app were reporting on certain places, as they happen. Let’s call it a live map. Full post here.

Inspired by PhoenixDiff, Elixir Diff helps you compare projects generated using mix new, mix phx.new, etc. You can also compare various CLI flags. https://elixirdiff.com/
