defmodule Mix.Tasks.Ecto.Create do

import Mix.Ecto
@shortdoc "Creates the repository storage"
@moduledoc """
Create the storage for the given repository.
The repositories to create are the ones specified under the
`:ecto_repos` option in the current app configuration. However,
if the `-r` option is given, it replaces the `:ecto_repos` config.
Since Ecto tasks can only be executed once, if you need to create
multiple repositories, set `:ecto_repos` accordingly or pass the `-r`
flag multiple times.
## Examples
mix ecto.create
mix ecto.create -r Custom.Repo
## Command line options
* `-r`, `--repo` - the repo to create
* `--no-compile` - do not compile before creating
* `--quiet` - do not log output
