Vim打造成GoLang开发环境

源码安装GoLang

安装： tar -xzf go1.16.darwin-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=$PATH/bin:$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 .'
alias cover="go test -coverprofile=cover.out"
alias covers="go tool cover -html=cover.out"

配置go env：

go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,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 install google.golang.org/protobuf/cmd/protoc-gen-go@latest 
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
go install github.com/envoyproxy/protoc-gen-validate@latest

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 

vim .vimrc

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
