Vim から neovim に移行する

2020/07/24 13:45

Vim から neovim に移行したのでメモ

モチベ

  • neovim 使ったことないので試してみたい

  • neovim じゃないと使えない機能がある

    • coc.nvim の VIRTUAL_TEXT とか

手順

最終的な設定は dotfiles のリポジトリを参照

インストール

  • brew install neovim
  • :help nvim-from-vimを読む
  • ~/.config/nvim/init.vim 作成
set runtimepath^=~/.vim runtimepath+=~/.vim/after
let &packpath = &runtimepath
source ~/.vimrc

ttymouse optionを書き換える

if !has('nvim')
  set ttymouse=xterm2
endif

vimと共存するためシンボリックリンクとかで設定ファイルやautoloadのディテクトリを共有

dotfilesで管理してるのでdotfilesベースで

ln -s ~/dotfiles/vim/nvim/init.vim ~/.config/nvim/init.vim
ln -s ~/dotfiles/vim/.vim/* ~/.config/nvim/

最終的に~/.vim と ~/.config/nvim の中身が init.vim 以外同じになってれば良い

エラーを潰していく

ここから :checkhealthで発生している問題を確認しながら解決していく

tmux

発生したエラー

## tmux
OK: escape-time: 1ms
INFO: $TERM: xterm-256color
INFO: default-terminal: screen-256color
ERROR: $TERM differs from the tmux `default-terminal` setting. Colors might look wrong.
  ADVICE:
    $TERM may have been set by some rc (.bashrc, .zshrc, ...).
WARNING: Neither Tc nor RGB capability set. True colors are disabled. 'termguicolors' won't work properly.
  ADVICE:
    Put this in your ~/.tmux.conf and replace XXX by your $TERM outside of tmux:
      set-option -sa terminal-overrides ',XXX:RGB'
    For older tmux versions use this instead:
      set-option -ga terminal-overrides ',XXX:Tc'

解決 .tmux.confの変更

# color
set -g default-terminal "screen-256color"
set-option -sa terminal-overrides ",*256col*:RGB"

.zshrcの変更

export TERM=screen-256color
set termguicolors

Rubyのprovider

発生したエラー

## Ruby provider (optional)
  INFO: Ruby: ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]
  WARNING: `neovim-ruby-host` not found.
    ADVICE:
      Run `gem install neovim` to ensure the neovim RubyGem is installed.
      Run `gem environment` to ensure the gem bin directory is in $PATH.

      See :help g:ruby_host_prog for non-standard gem installations.

解決

sudo gem install neovim

`npm i -g neovim`

:checkhealth以外で発生したエラー

clipboardの設定

Error detected while processing /Users/ebiken/dotfiles/vim/base.vim:
line  103:
E474: Invalid argument: clipboard=unnamed,autoselect

解決 nvimのときは autoselectを指定しないようにして解決

  • サポートしてないらしい
if has('nvim')
  set clipboard=unnamed
else
  set clipboard=unnamed,autoselect
endif

移行した結果

fzf.vim の見た目がいい感じになった (左 neovim、右 vim8) fzf.vim

速さの違いはまだわからない。大きなファイルを扱うときに違いが出るかもしれない
