はじめに
Rails 6 に追加されそうな新機能を試す第12段。 今回のちょい足し機能は、 rails notes --annotations 編です。
rails notes コマンドに --annotations (-a) オプションが追加されました。
記載時点では、Rails は 6.0.0.rc1 です。 gem install rails --prerelease でインストールできます。
$ rails --version
Rails 6.0.0.rc1
プロジェクトを作成する
rails プロジェクトを作成します。
$ rails new sandbox6_0_0rc1
app/controllers/application_controller.rb にコメントを追加する
rails notes --annotations を試すためにコメントを追加します。
app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
# TODO: add common method in controllers
# FIXME: fix the bug
# NOTE: this test for rails notes
end
rails notes --help を実行する
rails notes --help を実行すると --annotations(-a)` オプションがあることがわかります。
$ rails notes --help
Usage:
rails notes [options]
Options:
-a, [--annotations=one two three] # Filter by specific annotations, e.g. Foobar TODO
# Default: ["OPTIMIZE", "FIXME", "TODO"]
rails notes --annotations
--annotations オプションを試してみます。
$ rails notes --annotations FIXME NOTE
app/controllers/application_controller.rb:
* [3] [FIXME] fix the bug
* [4] [NOTE] this test for rails notes
-a でも同じ結果になります
$ rails notes -a FIXME NOTE
app/controllers/application_controller.rb:
* [3] [FIXME] fix the bug
* [4] [NOTE] this test for rails notes
おまけ
rails notes -a だけだとエラーになりました。
$ rails notes -a
