Pretty printing for Elixir

This pretty printer is inspired in the pp macro from Crystal: [https://crystal-lang.org/api/toplevel.html#pp%28%2Aexps%29-macro]. It's quite useful while doing print debugging.

Installation

The package can be installed by adding pp to your list of dependencies in mix.exs:

def deps do
  [
    {:pp, "~> 0.1.0"}
  ]
end

Usage

In order to use the pp macro, first import the PP module in your code:

import PP

Now you're ready to use the macro:

x = 1
y = 2
pp x + y, :red

When that code is executed, it will print in the console in red color:

x + y # => 3
