如何得知当前光标下的syntax组

stack overflow: Find out to which highlight-group a particular keyword/symbol belongs in vim

" adds to statusline
set laststatus=2
set statusline+=%{synIDattr(synID(line('.'),col('.'),1),'name')}

" a little more informative version of the above
# nmap <Leader>sI :call <SID>SynStack()<CR>
# nmap <C-S-P> :call <SID>SynStack()<CR>

function! <SID>SynStack()
    if !exists("*synstack")
        return
    endif
    echo map(synstack(line('.'), col('.')), 'synIDattr(v:val, "name")')
endfunc

syntax files

前言：为了修复.dot文件注释斜线超过2条，会影响后面行的问题

结论：缺少keepend参数，添加~/.vim/after/syntax/dot.vim覆盖$VIMRUNTIME/syntax/dot.vim的对“//”的定义即可。

  • :h :syn-files
    • :h mysyntaxfile 新增syntax file
    • :h mysyntaxfile-add 在原有syntax file上修补
