2. neovim の設定

  • ~/.vimrc ではなく、~/.config/nvim/init.vim に設定を書きます。

  1. Configuration nvim-configuration

  2. Use $XDG_CONFIG_HOME/nvim/init.vim instead of .vimrc for configuration.

  3. Use $XDG_CONFIG_HOME/nvim instead of .vim to store configuration files.
  4. Use $XDG_DATA_HOME/nvim/shada/main.shada instead of .viminfo for persistent session information. |shada|

XDG_CONFIG_HOME

  • ユーザー個別の設定が書き込まれるディレクトリ (/etc と類似)。
  • デフォルトは $HOME/.config です。
$ mkdir ~/.config/nvim
  • ~/.config/nvim/init.vim の作成
