打造超级舒适的Go开发环境之VIM配置

最近博主已经从VIM迁移到了EMACS作为主要生产工具，目的是为了学习Lisp和体验EMACS操作系统之美，哈哈，不要被我弄的技术焦虑，没错，我就是换了个吃饭的盘子。写下这篇博客也是为了纪念我顺利的“从VIM毕业了”。

在阅读本文之前，你需要：

• 准备一个UNIX like的操作系统
• 一个可以跨过山和大海的代-理

话不多说，开始吧~

（1）下载必要的Go工具链

go get -v github.com/mdempsky/gocode
go get -v github.com/ramya-rao-a/go-outline
go get -v github.com/acroca/go-symbols
go get -v github.com/uudashr/gopkgs
go get -v golang.org/x/tools/cmd/guru
go get -v golang.org/x/tools/cmd/gorename
go get -v github.com/sqs/goreturns
go get -v github.com/rogpeppe/godef
go get -v golang.org/x/tools/cmd/godoc
go get -v golang.org/x/lint/golint
go get -v github.com/derekparker/delve/tree/master/cmd/dlv
go get -v github.com/fatih/gomodifytags
go get -v github.com/haya14busa/goplay
go get -v github.com/josharian/impl
go get -v github.com/tylerb/gotype-live
go get -v github.com/cweill/gotests
go get -v github.com/sourcegraph/go-langserver
go get -v github.com/davidrjenni/reftools/tree/master/cmd/fillstruct

（2）安装VIM

macOS用户可能需要安装一下macvim：

brew install macvim

（3）主题配置

为了实现类似于Atom的Onedark和Onelight模式，我们可能需要安装两个主题：

• onedark.vim(只支持黑暗模式)：https://github.com/joshdick/onedark.vim.git
• one.vim(同时支持)：https://github.com/rakr/vim-one.git

在.vim目录下创建三个目录：autoload,bundle,colors，将两个仓库克隆到本地，然后将autoload目录的one.vim或者onedark.vim拷贝到autoload目录，将colors目录的one.vim或者onedark.vim拷贝到colors目录。

配置主题，修改~/.vimrc文件：

colorscheme one
set background=dark

当你想要将主题更改为Onelight的时候，只要将dark替换为light即可。

（4）插件配置

首先要安装插件管理器Vundle：

git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

然后配置~/.vimrc文件：

set nocompatible              " be iMproved, required
filetype off                  " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin(‘~/some/path/here‘)

" let Vundle manage Vundle, required
Plugin ‘VundleVim/Vundle.vim‘

" The following are examples of different formats supported.
" Keep Plugin commands between vundle#begin/end.
" plugin on GitHub repo
Plugin ‘tpope/vim-fugitive‘
" plugin from http://vim-scripts.org/vim/scripts.html
" Plugin ‘L9‘
" Git plugin not hosted on GitHub
Plugin ‘git://git.wincent.com/command-t.git‘
" git repos on your local machine (i.e. when working on your own plugin)
Plugin ‘file:///home/gmarik/path/to/plugin‘
" The sparkup vim script is in a subdirectory of this repo called vim.
" Pass the path to set the runtimepath properly.
Plugin ‘rstacruz/sparkup‘, {‘rtp‘: ‘vim/‘}
" Install L9 and avoid a Naming conflict if you‘ve already installed a
" different version somewhere else.
" Plugin ‘ascenator/L9‘, {‘name‘: ‘newL9‘}

" All of your Plugins must be added before the following line
call vundle#end()            " required
filetype plugin indent on    " required
" To ignore plugin indent changes, instead use:
"filetype plugin on
"
" Brief help
" :PluginList       - lists configured plugins
" :PluginInstall    - installs plugins; append `!` to update or just :PluginUpdate
" :PluginSearch foo - searches for foo; append `!` to refresh local cache
" :PluginClean      - confirms removal of unused plugins; append `!` to auto-approve removal
"
" see :h vundle for more details or wiki for FAQ
" Put your non-Plugin stuff after this line

为了支持多种编程语言，我们采用YouCompleteMe插件，macOS用户使用如下命令：

brew install cmake python python3 mono go nodejs

如果你已经使用nvm作为Node.js版本管理器，或者已经通过PKG方式安装了Python3.x版本，那么只需要PATH可以识别到命令，另外nvm用户需要安装npm：

brew install npm

接下来需要进行编译：

cd ~/.vim/bundle/YouCompleteMe
python3 install.py --all

由于YouCompleteMe插件使用Vundle安装可能导致失败，因此通过手动安装的方式实现，其他插件均可以通过Vundle安装：

Plugin ‘fatih/vim-go‘
Plugin ‘Tagbar‘
Plugin ‘scrooloose/nerdtree‘
Plugin ‘Xuyuanp/nerdtree-git-plugin‘
Plugin ‘vim-airline/vim-airline‘
Plugin ‘vim-airline/vim-airline-themes‘

写到.vimrc文件中，然后打开vim，进入命令模式，使用如下命令安装：

:PluginInstall

vim-go插件需要下载一些工具包，如果使用Vundle安装失败，可以进入vim使用如下命令：

:GoInstallBinaries

配置完成后的整个.vimrc文件如下：

set nocompatible              " be iMproved, required
filetype off                  " required
