Vim打造成GoLang开发环境
源码安装GoLang
进入：https://golang.google.cn/dl/
下载：wget https://golang.google.cn/dl/go1.14.6.darwin-amd64.tar.gz
安装： tar -xzf go1.14.6.linux-amd64.tar.gz -C /usr/local
配置环境变量：vim ~/.bash_profile
export GOROOT=/usr/local/go
export GOPATH=/Users/why/Desktop/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
alias gosrc="cd $GOROOT/src"
alias gopath="cd $GOPATH"
alias gomod="cd $GOMOD"
alias gorm='gormt -g=true'
alias gotest='gotests -all -w ./'
alias goformat='gofmt -l -w -s ./'
alias goimport='goimports -l -w ./'
alias gorace='go run -race .'
配置go env：
go env -w GO111MODULE=on
go env -w GOPROXY="https://goproxy.io,direct"
go env -w GOROOT=/usr/local/go
go env -w GOBIN=/usr/local/go/bin
go env -w GOPATH=/Users/why/go
安装Go相关工具
这里只列出来一部分，剩下的按需安装

go get -u -v github.com/golangci/golangci-lint/cmd/golangci-lint
go get -u -v github.com/xxjwxc/gormt@master （gormt -g=true）
安装代码规范检测工具
这个弥补 golint 的不足
brew install golangci-lint
Vim编译器配置
vim-go 必须保证 vim 版本是8以上，运行 vim 命令查看，可以通过源码安装，如果已经是是请忽略。
yum remove vim
github下载源码：https://github.com/vim/vim
cd ./vim/src
./configure
make && make install
提前下载 vim 插件源码包：
mkdir ~/.vim/bundle
cd ~/.vim/bundle
git clone https://github.com/VundleVim/Vundle.vim.git
git clone https://github.com/fatih/vim-go.git
git clone https://github.com/dgryski/vim-godef
git clone https://github.com/Blackrush/vim-gocode.git
git clone https://github.com/mattn/vim-goimports.git
git clone https://github.com/jstemmer/gotags.git
mkdir ~/.vim/colors
cd ~/.vim/colors
git clone https://github.com/tomasr/molokai.git
cp ~/.vim/colors/molokai/colors/molokai.vim ~/.vim/colors

安装 vim go 工具，这里需要保证go工具命令目录在环境变量或者bin目录可以找到：
vim
:GoInstallBinaries
安装 vimrc 中 包含的 Plugin 插件：
vim
:PluginInstall
汇总一下快捷键命令：
- F2：代码提示
- F3：开启关闭NERDTree（也可以:NERDTree）
- F4：右侧展示文件结构
- Ctrl + ]/o：代码追踪/回退
