global mode?

[luciferasm]

I always use highlight-symbol globally, and have therefore added the usual:
(defun highlight-symbol-mode-on () (highlight-symbol-mode 1))
(define-globalized-minor-mode global-highlight-symbol-mode highlight-symbol-mode highlight-symbol-mode-on)

in order to just enable it globally with

(global-highlight-symbol-mode 1)

Is there a reason why this standard global construct is left out?

I suppose the reason is that it's only designed (and tested) to be used during coding. As you found out yourself (#10), it won't work in all buffers, and I have no idea what would happen in other special buffers.

I don't want to add a global mode unless somebody has an idea how to limit it to reasonably compatible buffers.

I use this code:

(setq highlight-symbol-disable '())
(add-hook 'after-change-major-mode-hook
          (lambda ()
            (if (null (memql major-mode highlight-symbol-disable))
                (highlight-symbol-mode))))

If I will need to disable the mode for some buffers I just append the name of that major mode to the list.

Hi, thanks for your answer!

But sometimes it is not enough to detect an incompatible environment by just looking at the major-mode. E.g. M-x list-colors-display or M-x list-faces-display uses Help major mode, but you don't want to always disable highlight-symbol in Help mode in general. Also, it seems more high-level to define a proper global-mode than using hooks. Therefore I currently use:

(defun highlight-symbol-mode-on ()
(unless (or (minibufferp)
(member major-mode '()) ;;list of incompatible major modes
(member (buffer-name) '("Faces" "Colors"))) ;;list of incompatible buffer names
(highlight-symbol-mode 1)))

(define-globalized-minor-mode
global-highlight-symbol-mode
highlight-symbol-mode
highlight-symbol-mode-on)

(global-highlight-symbol-mode 1)

Best regards,

It would be great if you could add @luciferasm code

I don't think a manual list of incompatible modes and buffer names is safe enough to ship. I think that only works if customized for the actual user.

A whitelist approach might work, though.

in emacs 24 you can use prog-mode-hook (and also text-mode-hook if you want) to hook into all programming language modes (and text modes), which is quite a sane way to enable highlight-symbol-mode for anything that is not a special buffer.

(defun my-hls-hook ()
  (when (featurep 'highlight-symbol)
    (highlight-symbol-mode t)
    (highlight-symbol-nav-mode t)
    ))

(add-hook 'find-file-hook 'my-hls-hook)
