Boxen uses a bunch of shellscripts to insert itself into your environment on shell load.

These assume a POSIX shell, which fish is not.

Run this script to generate a fish-compatible config file in ~/.config/fish/boxen.fish, which you can source at the end of your ~/.config/fish/config.fish.

Dir.chdir("/opt/boxen") do

  File.open(File.expand_path("~/.config/fish/boxen.fish"), "w") do |f|
