Morphix is a small library of convenience methods for manipulating Enums, including flattening lists and tuples, converting strings to atoms, and odder things.

The new partiphify method divides a list into k balanced sublists, such that:

> Morphix.partiphify!([:a,:b,:c,:d,:e,:f,:g,:h,:i,:j], 4)
[[:e, :f], [:g, :h], [:i, :a, :b], [:j, :c, :d]]

The difference between Morphix.partiphify and Enum.chunk is twofold: first, you always get k sublists, even if one or more are empty, and second, the output list sizes are balanced. The use case it was designed for was dividing a list of inputs across a fixed number of workers.

We built an in-browser Elixir formatter so everyone can use the new formatter today without installing 1.6-dev.

Elixir is mostly used for writing server-based software, but there’s no reason that has to be the case. It’s useful for quick user-scripts too. Here’s a blog post documenting the steps required to distribute your new Elixir script via Homebrew. Enjoy!

Recently I got an opportunity to write a simple Telegram bot. The purpose of this bot is very simple: it has to send random quotes of Victor Pelevin for any user interaction. I decided to write this bot in Elixir. So in this post I will try describe the bot’s implementation.

While working on http://app.twch.at/, I needed a way to store arbitrary files (e-mail bodies, images, etc) with Arc. However, I didn’t see a point in using S3 immediately, especially because I wanted tests to run against an actual instance in integration without incurring (negligible) fees.

I wrote about this here: https://jacky.wtf/weblog/arc-minio/

Part 1: Elixir web development 101: introduction & toolchain setup

Part 2: Elixir web development 101: collaborative todolist with realtime updates

This two-part serie started as a brain dump of my first steps in Elixir & Phoenix web development and ended as a small tutorial on how to build a collaborative todo app with realtime updates using websockets. Hope it helps to get you started!

The code is available on Github.

If neither belongs_to nor has_one/has_many seem to fit your use case maybe take a look at ectos abstract tables. https://medium.com/@lostkobrakai/phoenix-contexts-and-ecto-abstract-tables-e6b4de93edf

This post is about the 5 reasons that made me switch and why you should consider using Phoenix instead of Rails in your next project • http://elviovicosa.com/blog/2017/11/23/5-reasons-to-use-phoenix-instead-of-rails.html

Our project has just been accepted by RealWorld.io and is now on their backend ranking.

-> https://github.com/gothinkster/elixir-phoenix-realworld-example-app

Me and many other contributors of the (amazing) elixir community have created this Elixir + Phoenix project which implements the RealWorld.io specs.

If you’re in the competitive spirit, the ranking is ordered by GitHub stars, so star the above repo so we can get to the podium!

Currently: #1 Node/Express with 605, #2 Laravel with 359 and #3 Django with 224

A big thank you to all who have contributed so far! And of course, contributions are still very much welcome!

I have written a blog post showing how to memoize functions in Elixir and providing the scaffold for the Memoize module that could be used as

use Memoized, name: FortyTwo, fun: fn -> Process.sleep(1_000); 42 end

I’ve written a blog post on how I test a specific doctest. Useful when you want to zero-in on a failing test.

I expand and refactor my approach in part 2 of my article on Composable Queries with Ecto. Bringing a modular approach to how we craft queries make complex requests simple. https://blog.echobind.com/composable-queries-with-ecto-part-2-e590af56d741

More metaprogramming mayhem from me with the first release of plymio_ast_vorm, a toolkit for managing a collection of Quoted Forms (Asts).
