IntelliJ Elixir v10.3.0

  • Add Type Specifications to Dbgi tab for :elixir_erl backend for .beam files.
  • Cache all computed Elixir levels at the file, module, project, and SDK levels. The computed Elixir level is used to determine how to emulate the various grammar changes made for the different Elixir versions. This bug was potentially introduced as earlier asv7.0.0 (2017-12-15) and as late as v7.5.0 (2018-06-03) as that’s the history for and has affected all later versions. If you ever experienced the 6.X series as faster than the 7.X series and later, this bug may be why and you should upgrade/reinstall immediately.

Installation Instructions

Credo v1.0.3 released

I released v1.0.3 of Credo, the static code analysis tool emphasizing code consistency and teaching.

For details, please refer to the CHANGELOG.

Que v0.9 released! 🎉

Que v0.9 brings massive improvements to the performance and reliability of job workers, especially under high load / concurrency. 🎉🎉🎉


Que is a simple background job processing library for Elixir that’s backed by Mnesia for storage. That makes it fast, reliable and still super easy to use without depending on any external services like Redis. 🙌

Credo, a new static code analysis tool that acts as a code linter, but also focusses on teaching coding practices and code consistency.

Using Control Flow in Elixir to Improve Discoverability

Code is read many more times than it is written, so it is important to us that our code is understandable. Here are a couple of guidelines we tend to follow in order to boost the discoverability and convey purpose to the reader.

QuickFormat for running the formatter without BEAM startup

I made for my own usage when formatting on save in Vim, because the latency was getting to me. It’s a little rough around the edges, but maybe someone will find it of use.

Pattern Matching to Format Text

Elixir supports pattern matching strings, making formatting text like phone numbers, SSNs, and more very clean and fun.

Spawning processes in Elixir, a gentle introduction to concurrency

Spawning processes in Elixir, a gentle introduction to concurrency

Along with pattern matching, one of the coolest things in Erlang and Elixir is their concurrency implementation based on Actor model. In this article I introduce concurrency and show how we can start making our code concurrent in Elixir, using processes.

Memento v0.3.0 released


Memento is a fast and easy-to-use Mnesia wrapper for Elixir.

The latest release of Memento includes important changes that improve its reliability and overall performance under high-load.

Salsa dancing website:

I just released a new salsa and latin dancing website built with Elixir, Phoenix, and Vue. The main feature to start is a weekly-ish newsletter with a new move or step that’s been added to the site. We will aggregate the best videos demonstrating the move. I’ve been doing a lot with Rails lately so it was a great joy to work in Elixir and Phoenix again, and get a feel for incorporating Vue and SASS now that Phoenix is using Webpack.
