无法在vim中自动格式化go (golang)代码

Question

我在使用以下命令时遇到了问题：

autocmd FileType go autocmd BufWritePre <buffer> Fmt

它假定通过将代码放在.vimrc文件的末尾来自动格式化代码。

下面是我的.vimrc文件的外观：

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 'gmarik/Vundle.vim'

" 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/'}
" Avoid a name conflict with L9
Plugin 'user/L9', {'name': 'newL9'}
Plugin 'commentary.vim'
Plugin 'go.vim'

" All of your Plugins must be added before the following line
call vundle#end()            " required
filetype plugin indent on    " required

syntax on
filetype plugin on

filetype indent on

"autocmd FileType go compiler go
autocmd FileType go autocmd BufWritePre <buffer> Fmt

然而，vim确实抛给我一个错误，说：

Error Detected while processing BufWrite Auto commands for "<buffer=1>"

E492: Not an editor command: Fmt

我不知道出了什么问题，特别是因为它之前是有效的。

您可能指的是由this定义的:Fmt命令。

看起来那个文件类型插件不是源码的。您可以使用:scriptnames命令进行检查；它需要包含ftplugin/go/fmt.vim。如果不是，则说明您的'runtimepath'选项有问题。

或者，您可以使用fatih/vim-go；它显然具有自动格式化Go源代码的配置，因此您不需要自己定义该:autocmd。
