autocmd bufnewfile在相对路径上导致“Trailing characters”错误

Question

我遇到了问题，我的.vimrc文件。我已经完成了所有python和sh文件的自动命令。我已经在下面列出了。

gvim test.py 

如果我使用的路径相对于当前工作目录，但是，如：

gvim ../test.py 

我收到以下错误：

Error detected while processing BufNewFile Auto commands for "*.{py,sh}"

E488: Trailing characters

使用的直接路径，即当所有的作品如预期

有关如何解决此问题的任何想法？

autocmd bufnewfile *.{py,sh} 
\ let path = expand("~/bin/Templates/")| 
\ let extension = expand("%:e")| 
\ let template = path . extension| 
\ let name = "John Doe" | 
\ if filereadable(template)| 
\ execute "silent! 0r" . template| 
\ execute "1," . 10 . "g/# File Name:.*/s//# File Name: " .expand("%")| 
\ execute "1," . 10 . "g/# Creation Date:.*/s//# Creation Date: " .strftime("%b-%d-%Y")| 
\ execute "1," . 10 . "g/Created By:.*/s//Created By: " . name| 
\ execute "normal Gdd/CURSOR\<CR>dw"| 
\ endif| 
\ startinsert! 

autocmd bufwritepre,filewritepre *.{py,sh} 
\ execute "normal ma"| 
\ execute "1," . 10 . "g/# Last Modified:.*/s/# Last Modified:.*/# Last Modified: " 
\ .strftime("%b-%d-%Y") 

autocmd bufwritepost,filewritepost *.{py,sh} 
\ execute "normal 'a" 

模板为Python文件如下：

所有的

#!/usr/bin/python 
# File Name: <filename> 
# Creation Date: <date> 
# Last Modified: <N/A> 
# Created By: <Name> 
# Description: CURSOR 

Answer 1

首先，让我们来看看:help 10.2：

The general form of the `:substitute` command is as follows: 
    :[range]substitute/from/to/[flags] 

请保持/[flags]记在心里。现在，当你在命令行中输入gvim test.py，下面的命令在Vim中执行：

:s//# File Name: test.py 

但是当你进入gvim ../test.py，Vim执行：

:s//# File Name: ../test.py 

所以Vim使用test.py为:substitute的标志和这不是理想的行为。

您需要的是将expand("%")替换为expand("%:t")以仅获取文件名。详情请参阅:help expand()。
