NeoVim 설치 & 사용 방법
개발환경 설정 - NeoVim
NeoVim 설치
macOS (apple silicon)
$ brew install neovim
Ubuntu
sudo apt install neovim
configuration
~/.vimrc 파일의 내용을 그대로 ~/.config/nvim/init.vim 파일에 붙여넣으면 된다.
패키지 매니저 설치
NeoVim 패키지 매니저에는 Packer.nvim Vim-Plug dein.vim Vundle이 있다.
Packer 설치
$ brew install lua
$ mkdir -p ~/.local/share/nvim/site/pack/packer/start
$ cd ~/.local/share/nvim/site/pack/packer/start
$ git clone https://github.com/wbthomason/packer.nvim.git
~/.config/nvim/init.vim 파일에 설정 추가
" Packer 설치
packadd packer.nvim
" Packer 설정
call packer#init()
" 플러그인 추가
packer.add('tpope/vim-fugitive')
" 플러그인 설치
call packer#install()
Vundle 설치
$ git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
~/.config/nvim/init.vim 파일에 설정 추가
링크의 코드를 파일 맨 위에 추가하면 된다.
Plugin 설치
bufferline
현재 편집중인 파일들을 탭으로 정리해주는 플러그인
설치 (Vundle 사용)
~/.config/nvim/init.vim
Plugin 'nvim-tree/nvim-web-devicons'
Plugin 'akinsho/bufferline.nvim'
nvim을 종료했다가 다시 실행하여 :PluginInstall 입력
init.vim에서 필요없어진 플러그인은 Plugin 명령어를 지우고 :PluginClean을 입력하면 삭제된다.
설정
