以前是好用的，创建 python 文件可以自动插入文件头，但是现在不知道怎么回事，就是无法插入成功，只是插入两行空行，没有任何文字，这是为什么呢?

[yangtukun1412]

你是不是用 nerdtree 新建的文件？

[xinali]

@yangtukun1412 不是，现在查到毛病出在哪里了，只要添加了安装插件的那些行就不会自动添加(也插入，但是插入的是空行），注释了或是不用插件就没有问题，没办法我只能重新定义了快捷键，自动插入是没招了

[yangtukun1412]

@xinali 嗯, 之前遇到过用 nerdtree 新建文件时 autocmd 不起作用的问题. 你可以把 vim-plug 管理插件的部分移到最前面试一下.

[ashfinal]

建议使用 ultisnips 来插入文件头。
你这么写到 vimrc 里显得有点乱。

[rainysia]

把这函数改改吧,

function! AutoSetFileHead()
if &filetype == 'sh'
call setline(1, "\#!/bin/bash")
elseif &filetype == 'python'
call setline(1,"#!/usr/bin/env python")
call append(line("."),"# -*- coding: UTF-8 -*-")
call append(line(".")+1, "")
normal G
normal o
normal o
endif
endfunc

call plug#begin('~/.vim/plugged') 会调用 filetype off 这是这个插件比较恶心的地方
