VSCode+DanceでKakouneのキーバインディングを試す

Last updated at 2023-07-22Posted at 2023-06-27

概要

VSCodeで動くDanceという機能拡張を使って、Kakoune風のキーバインディングを設定する方法のメモです。

Kakouneとは？

複数選択+操作を基本としたLinux/Unix用のモード付きテキストエディタです。
詳しくはkakoune wikiのOnboardingを参考にしてください。Vimからの移行についても言及があります。
これまで試す機会がなかったのですが、VSCode+Danceの組み合わせでWSLやCygwinのないWindowsでも試そうです。

Danceとは？

Kakouneからインスピレーションを得た、 Visual Studio Codeのキーバインディング、モード、メニュー、およびスクリプトです。(Google翻訳使用)
DanceはUSキーボード用の設定に(おそらく)なっているので、JISキーボードで使うためには一部のキーバインディングを変更する必要があります。
私はJISキーボードを使っているので、keybindings.jsonでキーバインディングを変更しました。

手順

VSCodeにDanceを導入する
- VSCodeVim等、競合しそうな機能拡張があるなら無効化しておく
JISキーボードを使用している場合、Ctrl+Shift+P open keyboard shortcuts json 等としてkeybindings.jsonを開いて下記の設定をコピペする
同様に open user settings json 等としてsettings.jsonを開いて下記の設定をコピペする

注意

常用できていないので設定に多分ミスがあります。気付いたら(追記などの表記なしで)サイレントに直します。
shift+y、shift+alt+yにdanceのleap.nvim相当の機能(sneak風の2打移動)を割り当ててありますが、kakoune本来の機能・割り当てではありません。
