如何在vim中修改现有的高亮组？

Question

例如,如果我通过链接在vim中有一个现有的突出显示组

hi link my_highlight_group my_default_color

是否可以在不更改my_default_color的情况下将'bold'添加到my_highlight_group？以下不起作用:

hi my_highlight_group gui=bold

令人惊讶的是,如果直接定义my_highlight组(不是通过链接),我可以添加粗体:

hi my_highlight_group guifg=#F0000
hi my_highlight_group gui=bold

正如"太多的PHP"所说,没有直接的方式来说"创造一个看起来像那个并加上大胆的价值".最好的方法是修改配色方案.如果您没有使用自定义配色方案,请将主vim安装目录中的一个复制到〜/ .vim/colors目录并编辑它以适合您.或者,搜索vim脚本页面并尝试其中一些可用的.

无耻的插件:如果你想要一个比标准格式更容易编辑,请尝试我的"强盗"配色方案.

如果你真的希望能够动态添加粗体,你需要一个相当复杂的脚本,如下所示.请注意,除非您在加载配色方案后自动调用它或执行以下操作,否则不会为下次会话保存此内容:

:autocmd ColorScheme AddBoldToGroup my_highlight_group

所有这些剧本的剧本如下.据我所知,没有明显更快的方法!显然,你可以通过编写更简洁的代码来节省几行,但是使用redir和silent hi重复使用的一般想法是唯一的方法.

" Call this with something like
"
" :AddBoldToGroup perlRepeat
"
command! -complete=highlight -nargs=1 AddBoldToGroup call AddBoldToGroup(<f-args>)
function! AddBoldToGroup(group)
    " Redirect the output of the "hi" command into a variable
    " and find the highlighting
    redir => GroupDetails
    exe "silent hi " . a:group
    redir END

    " Resolve linked groups to find the root highlighting scheme
    while GroupDetails =~ "links to"
        let index = stridx(GroupDetails, "links to") + len("links to")
        let LinkedGroup =  strpart(GroupDetails, index + 1)
        redir => GroupDetails
        exe "silent hi " . LinkedGroup
        redir END
    endwhile

    " Extract the highlighting details (the bit after "xxx")
    let MatchGroups = matchlist(GroupDetails, '\<xxx\>\s\+\(.*\)')
    let ExistingHighlight = MatchGroups[1]

    " Check whether there's an existing gui= block
    let MatchGroups = matchlist(ExistingHighlight, '^\(.\{-}\) gui=\([^ ]\+\)\( .\{-}\)\?$')
    if MatchGroups != []
        " If there is, check whether "bold" is already in it
        let StartHighlight = MatchGroups[1]
        let GuiHighlight = MatchGroups[2]
        let EndHighlight = MatchGroups[3]
        if GuiHighlight =~ '.*bold.*'
            " Already done
            return
        endif
        " Add "bold" to the gui block
        let GuiHighlight .= ',bold'
        let NewHighlight = StartHighlight . GuiHighlight . EndHighlight
    else
        " If there's no GUI block, just add one with bold in it
        let NewHighlight = ExistingHighlight . " gui=bold"
    endif

    " Create the highlighting group
    exe "hi " . a:group . " " NewHighlight
endfunction
