As of November 6th, 2013 when searching for the term "elixir" github finds 644 repositories.
People learning Elixir...
There are large number of those that indicate they are code someone is writing while learning Elixir. Many from "Programming Elixir", "Introducing Elixir", a few from "Erlang and OTP in Action", "Learn you some erlang for grat good", and some other interesting book translations such as "Programming Challenges", Matasano Crypto Challenge, and "Code samples from the Handbook of Neuroevolution through Erlang in both Erlang and Elixir"
- 13 "elixir learning"
- 41 "elixir programming"
- 23 "elixir book"
- 20 "elixir exercises"
- remove duplicates and non-learning related => ~50
- say 50+ repos?
Of the 644 repositories 155 have been updated with in the last 30 days.
Here is a quick overview of some those with activity in the last 30 days which caught my eye.
Everyone loves writing JSON libraries it seems as we now have a bunch of them. The native json lib, cblage / elixir-json, -- https://github.com/cblage/elixir-json -- may be interesting Syntax and name spacing is still chaos, but you can now test their performance with: https://github.com/mrshankly/json_bm (Benchmark Erlang and Elixir JSON libraries)
