vim - 我想自定义折叠折叠中显示的文本 vim

Question

我使用折叠来评论

#
Stuff between the # are comments and automatically folded
#  

折叠起来是这样的

+--  4 lines: #--------------------------------------------------------------

我宁愿让他们说

+-- 4 Stuff between the # are comments and automatically folded

并且不会突出显示，或者在我的黑色终端上使它们成为白色背景。

我认为它是 foldtext 变量，正则表达式超出了我的范围。

除了方法 ZyX 显示，您还可以分配一个单独的函数来构建文本，如果您想进行更复杂的处理，这将特别有用。例如，

setlocal foldtext=MyFoldText()

function! MyFoldText()
  " do whatever processing you want here
  " the function will be called for each folded line visible on screen
  " the line number of each fold's "head" line will be in v:foldstart
  " last line of fold in v:foldend
  " can do whatever processing you want, then return text you want 
  " displayed:

  return my_processed_fold_text

endfunction

就高亮而言，折叠文本的整行将具有相同的高亮，这是由“折叠”高亮组决定的。因此，如果您希望它们是黑底白字:

:hi Folded guifg=white guibg=black ctermfg=white ctermbg=black

或者如果您希望它们以灰白色斜体显示:

:hi Folded guifg=#bbbbbb guibg=black gui=italic ctermfg=white ctermbg=black
