处理bufread自动命令时检测到的UNIX VIM错误

Question

我是本指南遵循本指南的新的VIM用户，可以自动制作VIM缩进python代码，并标记unnecssary whitespace：https：//realpython.com/blog/blog/python/vim-andon/vim-and-pym-and-python--python---------------------------er-python-in------------------------A-Match-Made-In-In-In-In-＃vim-Extensions

当我在.py文件上启动vim时，我已经收到此错误： Error detected while processing BufRead Auto commands for "*.py": E28: No such highlight group name: BadWhitespace

此错误我评论以下几行：

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

     set textwidth=79

     set fileformat=unix

Answer 1

有一个更简单的解决方案。您会发现我遇到了相同的问题，在这个小技巧之后，没有错误消息，一切正常。

技巧是，bufnewfile，bufread应该被一个空间分开。因此该线应该看起来像

au BufNewFile, BufRead *.py

而不是au BufNewFile,BufRead *.py 最好的问候

Answer 2

命令：

match BadWhitespace /s+$/

只要定义了BadWhitespace突出显示组，就会突出显示落后的白色空间。要检查是否定义了: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。

问题是多个 set s。该行的第一个set：

set tabstop=4

是命令，以下所有set s被视为参数。

应该看起来像这样：

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

另外：

" 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+$/
