Vim statusline不从表达式展开颜色/突出显示组 [英] Vim statusline does not expand color/highlight group from expression

问题描述

我写了一个函数，它返回一个字符串：

  StatusBricks（）
 let l：stat = Brick（statusbricks＃ReportLinecount（'raw'），{
 \'brick_color'：'LineNr'，
 \'delimiter_position'：'right '，
 \'delimiter_right'：'❯'
 \}）
 return l：stat 
 endfunction 
  

结果具有以下格式，由 Brick（）生成：

 ％＃HighlightGroup＃SomeData 
  

我使用函数作为状态行内的表达式，我期望突出显示组得到扩展，以便为适当的状态行部分着色：

  set statusline =％{StatusBricks（）} 
  

但是我得到的是一个statusline字面上显示％＃HighlightGroup＃ExpandedData ，而不是 ExpandedData ：

我做错了什么？

解决方案

％{的结果不会进一步解释， c $ c>％！是。使用

  set statusline =％！StatusBricks（）
  

％！在帮助文件中似乎没有标签，但在<$ c $ 如果您要在状态行中使用不同的颜色，请选择 在每个特定窗口的状态，然后你可以突出显示一个空字符串，如果你不想显示特定的高亮。例如

  set stl =％＃error＃％r％＃search＃
  / pre> 
 
 
只读只读窗口（例如打开帮助缓冲区）将使只读标志显示为红色。诚然，这可能会变得复杂，取决于您的突出显示要求。
 
I wrote a function which returns a string:
function! StatusBricks()
    let l:stat = Brick(statusbricks#ReportLinecount('raw'), {
        \ 'brick_color': 'LineNr',
        \ 'delimiter_position': 'right',
        \ 'delimiter_right': '❯'
        \ })
    return l:stat
endfunction
The result has the following format, generated by Brick():
%#HighlightGroup#SomeData
When I use the function as an expression inside the statusline I expect the highlight group to get expanded in order to colorize the appropriate statusline section:
set statusline =%{StatusBricks()}
But what I get is a statusline literally showing %#HighlightGroup#ExpandedData rather than ExpandedData:



What am I doing wrong?
解决方案
The result of %{ isn't interpreted further, however the result of %! is. Use
set statusline=%!StatusBricks()
%! doesn't appear to have a tag in the helpfile, but it's mentioned near the beginning of :help 'statusline'.

Following your comment: if you want different colours in the statusline depending on the state of each particular window, then you can highlight an empty string if you don't want a particular highlight to appear. E.g.
set stl=%#error#%r%#search#
Only read-only windows (e.g. open a help buffer) will have the read-only flag displayed in red. Admittedly this can get complicated depending on your highlighting requirements.
