There are two groups that determine highlighting of line displayed when &cursorline option is active: CursorLine and CursorLineNR. First is used to highlight the whole line, second for the line number. So to achieve what you want you must
-
Clear the highlighting of
CursorLine: justhi clear CursorLineafter any:colorschemeandset background=call.hi clear CursorLine augroup CLClear autocmd! ColorScheme * hi clear CursorLine augroup END -
Set the highlighting of
CursorLineNRif it is not set in your colorscheme:hi CursorLineNR cterm=bold augroup CLNRSet autocmd! ColorScheme * hi CursorLineNR cterm=bold augroup END(better to check whether it is already set in the colorscheme, maybe it will look better in that case).
You can join both autocommands in one of course.
CursorLineNR has been added relatively recently around version 7.3.488.
