Ion3

イントロダクション

Ion はタブフレームを備えたタイル型ウィンドウマネージャです。内蔵インタプリタとして Lua を使って全ての設定を管理しています。主としてキーボードを使って操作をするようになっていますが、マウスで操作することもできます。

インストール

Ion3 は こちらのニュース で書かれているように公式リポジトリには含まれていません。そのため ion3^AUR パッケージを使ってインストールする必要があります。

設定ファイルをホームディレクトリにコピーしてください:

$ cp /etc/ion3/* ~/.ion3

Ion3 を起動するには ~/.xinitrc に以下の行を追加:

exec ion3

後は以下で記述しているように Ion を設定してください。

ノート: 以下のファイルはデフォルトから大分修正が加えられています。
