Automatically highlighting the symbol under point

Automatically highlighting the symbol under point

[Colin Yates]

Hi (newbie warning!),

I am using prelude and if my point is over a symbol then I can call
'highlight-symbol-under-point' which works great. However, I can't
figure out how to turn it off.

Ideally, I would like it to automatically highlight the symbol under
point all the time, or at least when in a programming mode - is that
possible and any prior art you can point me at?

Thanks!

You can use `unhighlight-regexp' (on `C-x w r' and/or `M-s h u') for
this. It prompts for a regexp, but for your scenario you can just hit
`RET' to accept the default.

Check out `idle-highlight-mode' (available in MELPA) for that:

After you install it, you can active it in programming modes with
something like this:

    (defun my-programming-config ()
      (idle-highlight-mode 1))

    (add-hook 'prog-mode-hook #'my-programming-config)

Or alternatively, highlight-symbol-mode from

  https://github.com/nschum/highlight-symbol.el
