To use the new phx.new project generator, you can install the archive with the following command:
$ mix archive.install https://github.com/phoenixframework/archives/raw/master/phx_new.ez
Phoenix v1.3.0 is a backwards compatible release with v1.2.x. To upgrade your existing 1.2.x project, simply bump your phoenix dependency in mix.exs:
| defmodule Scream do | |
| defmacro scream!(ast) do | |
| {exclams, res} = count_exclams(ast, 0) | |
| case exclams do | |
| _ when exclams < 5 -> | |
| quote do "You say: #{inspect(unquote(res))}." end | |
| _ when exclams < 10 -> | |
| quote do "You yell: #{inspect(unquote(res))}!" end | |
| _ when exclams < 15 -> | |
| quote do "You scream: #{inspect(unquote(res))}!!" end |
