把vim当做golang的IDE

disl

　　开始决定丢弃鼠标，所以准备用vim了。
　　那么在vim里面如何搭建golang环境呢？
　　git盛行之下，搭建vim环境是如此简单。
　　而且vim搭建好了之后，基本上跟IDE没有差别。
　　高亮、自动补全、自动格式化、查看定义跳转、语法检测等等等等, 简直是不要不要的：

• Improved Syntax highlighting with items such as Functions, Operators, Methods.
  
• Auto completion support via gocode
  
• Better gofmt on save, which keeps cursor position and doesn't break your undo history
  
• Go to symbol/declaration with :GoDef
  
• Look up documentation with :GoDoc inside Vim or open it in browser
  
• Automatically import packages via :GoImport or plug it into autosave
  
• Compile your package with :GoBuild, install it with :GoInstall or test them with :GoTest (also supports running single tests via :GoTestFunc)
  
• Quickly execute your current file/files with :GoRun
  
• Automatic GOPATH detection based on the directory structure (i.e. gb projects, godep vendored projects)
  
• Change or display GOPATH with :GoPath
  
• Create a coverage profile and display annotated source code in browser to see which functions are covered with:GoCoverage
  
• Call gometalinter with :GoMetaLinter, which invokes all possible linters (golint, vet, errcheck, deadcode, etc..) and shows the warnings/errors
  
• Lint your code with :GoLint
  
• Run your code through :GoVet to catch static errors
  
• Advanced source analysis tools utilizing oracle, such as :GoImplements, :GoCallees, and :GoReferrers
  
• Precise type-safe renaming of>:GoRename
  
• List all source files and dependencies
  
• Unchecked error checking with :GoErrCheck
  
• Integrated and improved snippets, supporting ultisnips or neosnippet
  
• Share your current code to play.golang.org with :GoPlay
  
• On-the-fly type information about the word under the cursor. Plug it into your custom vim function.
  
• Go asm formatting on save
  
• Tagbar support to show tags of the source code in a sidebar with gotags
  
• Custom vim text objects such as a function or inner function list.
  
• A async launcher for the go command is implemented for Neovim, fully async building and testing (beta).
  
• Integrated with the Neovim terminal, launch :GoRun and other go commands in their own new terminal. (beta)
  
• Alternate between implementation and test code with :GoAlternate
  

　　安装起来也非常方便，只要一下三行代码：
　　

#下载安装　　git clone git@github.com:farazdagi/vim-go-ide.git ~/.vim_go_runtime
　　
sh ~/.vim_go_runtime/bin/install
　　

　　
#运行
　　
vim -u ~/.vimrc.go
　　

　　PS：
　　a）这里要求vim 要开启lua  ：
　　

brew install vim --with-lua --override-system-vim　　

　　b）如果需要类解析，需要转ctag
　　--------------------
　　2016-10-20补充
　　如果把go升级到go1.7，这里的函数 auto-complete 会显示PANIC不能显示任何的系统库对应的函数和自定义的函数
　　这里需要做一件事情，可以恢复
　　

ps aux | grep gocode　　

　　
#存在就干掉
　　

killall gocode　　

　　
#重启
　　
gocode
　　

　　或者采用以下方式
　　

gocode close && go get -u github.com/nsf/gocode
