This library extends linum-mode to highlight current line number. It requires Emacs 24.4 or later.
To use this package, add these lines to your .emacs file:
(require 'hlinum)
(hlinum-activate)And by using M-x linum-mode, you can see line numbers with highlighting current line number.
You can customize the color of highlighting current line by changing linum-highlight-face. By default, hlinum highlights current line only in the active buffer. To highlight current line in all buffers, change linum-highlight-in-all-buffersp to t.
