Today I Learned

A Hashrocket project

Shell Out With Elixir

Today I wrote a staging and production deploy script for Tilex, learning about System.cmd/3 along the way. The first argument to this function is the command, the second are arguments, and the third are options.

Here’s an example implementation from our script that deletes a Git tag and pushes that updated reference to origin:

System.cmd("git", ["tag", "-d", "staging"])
System.cmd("git", ["push", "origin", ":refs/tags/staging"])
Looking for help? Elixir is quickly gaining momentum for web applications that need concurrency, performance, and the ability to connect to many different clients. The developers at Hashrocket are learning along with the rest of the development community that Elixir and Phoenix are viable Rails alternatives for the right application.
