Lettuce is a generic server process that checks the files within an elixir
project that has lettuce as a dependency and then runs iex -S mix. It
initialises the state gen server with the .ex files inside lib and their
last modified time. By default lib is used but you specify which folders you
want to be watched.
If available in Hex, the package can be installed
by adding lettuce to your list of dependencies in mix.exs:
...
def deps do
[
{:lettuce, "~> 0.1.0", only: :dev}
]
end
...use Mix.Config
config :lettuce, folders_to_watch: ["apps"]
...You can also change the refresh time to control how often the project files will be checked.
use Mix.Config
config :lettuce, refresh_time: 1500
...Even though the start_link will throw an error if the Mix.env equals to
:dev it is recommended to explicitly select the extra applications by
environment in the mix file.
...
def application do
[
extra_applications: extra_applications(Mix.env(), [:logger, ...])
]
end
defp extra_applications(:dev, default), do: default ++ [:lettuce]
defp extra_applications(_, default), do: default
...While giving Node.js lessons as part of a charity called MigraCode in El Borne, Barcelona. We were reviewing some exercises and one of the steps in the instructions was to npm install nodemon, which reminded me of all the times I was inside IEx debbuging and I had to call recompile.
