VIM，手的延伸

Jan 2, 2019

团长：赶紧把这个Python脚本给我改好！

萌新：好的，先等我把Pycharm打开。

休闲玩家：你就不能用VIM？

用好一种可配置、可扩展、可编程的编辑器。学习它，扩展它，拥有它！

本文参考自：VIM and Python – A Match Made in Heaven，增加了Python-mode等插件。

安装插件

利用VIM 8的原生包管理功能，从GitHub上克隆以下插件到~/.vim/pack/foo/start目录：

YouCompleteMe（自动完成）
Python-mode（Python语法突显&代码重构）
emmet-vim（HTML & CSS）
NERDTree（目录文件导航）
vim-airline（状态条）
vim-fugitive（git扩展）
vimcdoc（中文文档）

mkdir -p $HOME/.vim/pack/foo/start
cd $HOME/.vim/pack/foo/start

sudo apt-get install -yqq --no-install-recommends build-essential cmake python3-dev
git clone --recurse-submodules "https://github.com/Valloric/YouCompleteMe.git"

git clone --recurse-submodules "https://github.com/python-mode/python-mode.git"
git clone "https://github.com/mattn/emmet-vim.git"
git clone "https://github.com/scrooloose/nerdtree.git"
git clone "https://github.com/vim-airline/vim-airline.git"
git clone "https://github.com/tpope/vim-fugitive.git"
git clone "https://github.com/yianwillis/vimcdoc.git"

配置VIM

添加插件的帮助文档：

vim -u NONE \
        -c "helptags YouCompleteMe/doc" \
        -c "helptags python-mode/doc" \
        -c "helptags emmet-vim/doc" \
        -c "helptags nerdtree/doc" \
        -c "helptags vim-airline/doc" \
        -c "helptags vim-fugitive/doc" \
        -c "helptags vimcdoc/doc" \
        -c q

在$HOME目录下，添加.vimrc文件，代码如下：

set nocompatible
syntax on
filetype off

set expandtab
set tabstop=4 shiftwidth=4 softtabstop=4
set autoindent

au BufNewFile,BufRead *.js,*.html,*.scss,*.yml,*.rb,Rakefile
