defmodule Phoenix.CodeReloader do
@moduledoc """
A plug and module to handle automatic code reloading.
For each request, Phoenix checks if any of the modules previously
compiled requires recompilation via `__phoenix_recompile__?/0` and then
calls `mix compile` for sources exclusive to the `web` directory.
To avoid race conditions, all code reloads are funneled through a
sequential call operation.
"""
## Server delegation
@doc """
Reloads code within the paths specified in the `:reloadable_paths`
config for the endpoint by invoking the `:reloadable_compilers`.
This is configured in your application environment like:
config :your_app, YourApp.Endpoint,
reloadable_paths: ["web"],
reloadable_compilers: [:gettext, :phoenix, :elixir]
Keep in mind that the paths passed to `:reloadable_paths` must be
a subset of the paths specified in the `:elixirc_paths` option of
`project/0` in `mix.exs` while `:reloadable_compilers` is a subset
of `:compilers`.
