Neovim+Coc.nvim配置终端代码编辑环境

2021-01-13 约 5355 字预计阅读 11 分钟次阅读

目前公司常用的环境还是linux的服务器，经常需要使用vim进行写代码，经过探索Neovim + Coc.nvim非常适合。以下全部采用源码安装（相比之下，直接用各个发行版的命令安装会更加简单）。参考博客

Neovim 和插件安装

1
2


wget https://github.com/neovim/neovim/releases/download/v0.4.3/nvim-linux64.tar.gz
tar -zxvf nvim-linux64.tar.gz

然后把neovim路径下的bin加入到~/.bashrc，然后在source一下就算是成功了。

插件安装

Vim-Plug

目前由于vim插件越来越多，由此也出现了插件管理工具，目前用得比较广泛的有：Vundle，vim-plug和dein,推荐使用vim-plug(对Vundle更好的替换)，关于dein，引用某巨佬的原话：“过度设计”。

1

sh -c 'curl -fLo "${XDG_DATA_HOME:-$HOME/.local/share}"/nvim/site/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'

这样，这个~/.local/share/nvim/site/autoload/plug.vim就会在你的目录下，并且vim会被调用。创建nvim的配置文件（这个配置文件和vim的.vimrc）一样：

1
2


mkdir ~/.config/nvim/
nvim ~/.config/nvim/init.vim

然后把

1
2


call plug#begin('~/.vim/plugged')
call plug#end()

加入到init.vim中，这样以后在call begin和call end之间加上插件就可以使用了。

之后的每个插件在init.vim文件中配置好后，要进行保存退出，再次进入nvim,使用命令 :PlugInstall安装

indentLine

indentLine此插件提供的一个可视化的缩进，把Plug 'Yggdroot/indentLine'，放到init.vim的call begin和call end之间，同时加入一些简单的配置：

1
2


let g:indent_guides_guide_size            = 1  " 指定对齐线的尺寸
let g:indent_guides_start_level           = 2  " 从第二层开始可视化显示缩进

vim-monokai

vim-monokai，这个插件是nvim的一个主题，monokai这个配色是比较经典好看的主题。

在call begin 和 call end之间加上Plug 'crusoexia/vim-monokai'，然后把

1

colo monokai

加到init.vim后面。

vim-airline

vim-airline给nvim提供一个强大的状态栏和标签栏，当打开多个文本时，可以用它进行快速的切换，是一个很强大的工具。

在call begin 和 call end之间加上：

1
2


Plug 'vim-airline/vim-airline'       
Plug 'vim-airline/vim-airline-themes' "airline 的主题

然后在init.vim里加上一些个性的配置：

nerdtree

nerdtree是一个树形的目录管理插件，可以方便在nvim中进行当前文件夹中的文件切换

在call begin 和 call end之间加上

" autocmd vimenter * NERDTree  "自动开启Nerdtree
let g:NERDTreeWinSize = 25 "设定 NERDTree 视窗大小
let NERDTreeShowBookmarks=1  " 开启Nerdtree时自动显示Bookmarks
"打开vim时如果没有文件自动打开NERDTree
" autocmd vimenter * if !argc()|NERDTree|endif
"当NERDTree为剩下的唯一窗口时自动关闭
autocmd bufenter * if (winnr("$") == 1 && exists("b:NERDTree") && b:NERDTree.isTabTree()) | q | endif
" 设置树的显示图标
let g:NERDTreeDirArrowExpandable = '+'
let g:NERDTreeDirArrowCollapsible = '-'
let NERDTreeIgnore = ['\.pyc$']  " 过滤所有.pyc文件不显示
let g:NERDTreeShowLineNumbers=0 " 是否显示行号
let g:NERDTreeHidden=0     "不显示隐藏文件
""Making it prettier
let NERDTreeMinimalUI = 1
let NERDTreeDirArrows = 1
nnoremap <F3> :NERDTreeToggle<CR> " 开启/关闭nerdtree快捷键

默认的情况下是关闭的，可以把autocmd vimenter * NERDTree的注释打开，改成默认开启的状态。同时把开关的按键映射到了F3，按下可以打开或关闭。

vim-cpp-enhanced-highlight

vim-cpp-enhanced-highlight，这个是用来加强C++的高亮的

1

Plug 'octol/vim-cpp-enhanced-highlight'

vim-snippets

honza/vim-snippets用来提供C++的snippets.

1

Plug 'honza/vim-snippets'

coc.nvim

coc.nvim是目前非常流行的，集代码补全、静态检测、函数跳转等功能的一个引擎。

安装coc.nvim，需要安装nodejs。和nvim一样，这个也有编译好的版本，解压后把bin的路径放到放到.bashrc里，之后运行

1

npm install -g neovim

在init.vim安装

1

Plug 'neoclide/coc.nvim', {'branch': 'release'}

CocVim

对于Python，直接装anaconda就行了，同时需要用pip装一下pynvim。

1

pip install pynvim
pip install -U jedi-language-server --use-feature=2020-resolver

在nvim输入:checkhealth，会进行基本环境的检查，保证你用的环境不会出问题即可. coc.nvim 提供了很多有用的扩展工具在coc extensions中，这些扩展在nvim中通过命令:CocInstall进行安装
