Question

我是一个新的vim用户，按照本指南自动生成vim indent python代码并标记不需要的空格：https://realpython.com/blog/python/vim-and-python-a-match-made-in-heaven/#vim-extensions

当我在.py文件上启动vim时遇到此错误：Error detected while processing BufRead Auto commands for "*.py": E28: No such highlight group name: BadWhitespace

此错误我注释掉以下几行：

" Flag unnecessary whitespace                                           
au BufRead,BufNewFile *.py,*.pyw,*.c,*.h match BadWhitespace /\s\+$/   <- this line   

" UTF8 Support

    \ set tabstop=4                                                     
"    \ set softtabstop=4      <-- this line                                          
    \ set shiftwidth=4                                                  
    \ set textwidth=79                                                  
    \ set expandtab                                                     
    \ set autoindent                                                    
    \ set fileformat=unix

Answer 1

命令：

match BadWhitespace /\s\+$/

如果定义了BadWhitespace突出显示组，

将突出显示尾随空格。要检查它是否已定义，请执行:highlight BadWhitespace。如果未定义，则可以使用默认突出显示组，例如：

match Cursor /\s\+$/

或定义BadWhitespace突出显示组。可能的颜色组合是：

:highlight BadWhitespace ctermfg=16 ctermbg=253 guifg=#000000 guibg=#F8F8F0

在使用BadWhitespace的autocmd之前添加此行代码。

Answer 2

有一个更简单的解决方案。您会发现我遇到了同样的问题，经过这个小技巧之后，没有错误消息出现，并且一切正常。

技巧是，BufNewFile，BufRead应该用空格分隔。所以这行看起来应该像

au BufNewFile, BufRead *.py

而不是au BufNewFile,BufRead *.py 最好的问候

Answer 3

或者来自here：

" Use the below highlight group when displaying bad whitespace is desired.
highlight BadWhitespace ctermbg=red guibg=red

" Display tabs at the beginning of a line in Python mode as bad.
au BufRead,BufNewFile *.py,*.pyw match BadWhitespace /^\t\+/

" Make trailing whitespace be flagged as bad.
au BufRead,BufNewFile *.py,*.pyw,*.c,*.h match BadWhitespace /\s\+$/

Answer 4

问题是多个set。此行的第一个set：

\ set tabstop=4

是命令，以下所有set都被当作参数。

它应该像这样：

au BufNewFile,BufRead *.py
    \ set tabstop=4
    \ softtabstop=4
    \ shiftwidth=4
    \ textwidth=79
    \ expandtab
    \ autoindent
    \ fileformat=unix

unix vim处理BufRead Auto命令时检测到错误
