ExGuard is a mix command to handle events on file system modifications, ExGuard heavily borrowed ideas/art works from Guard

1. Add ex_guard to your list of dependencies in mix.exs:

   def deps do
     [{:ex_guard, "~> 1.2", only: :dev}]
   end

2. Create a file named .exguard.exs in your root application directory:

   use ExGuard.Config
   
   guard("unit-test")
   |> command("mix test --color")
   |> watch(~r{\.(erl|ex|exs|eex|xrl|yrl)\z}i)
   |> notification(:auto)

   Look at .exguard.exs for more fine-grained config.

3. Run mix guard as soon as you change any file with above pattern, the test gets executed

Currently supports notification with tools:

• Terminal Title (Xterm)
• TMux (Universal)
• Terminal Notifier (mac only)
• Notify Send (linux distros)

In order to ExGuard sends notification, you need to make sure these tools are setup properly.
