Is there a better way to unhighlight all highlighted symbols in a buffer?
From C-h f unhighlight-regexp, we get
Remove highlighting of each match to REGEXP set by hi-lock.
Interactively, prompt for REGEXP, accepting only regexps
previously inserted by hi-lock interactive functions.
If REGEXP is t (or if C-u was ...
The following elisp snippet should do. The important details are:
Strings are handled by syntax highlighting and not by pattern matching (i.e., keyword highlighting). This has very high priority. So one needs to override it explicitly by the value t for the MATCHER flag OVERRIDE (see doc of font-lock-keywords).
One cannot use a regexp as keyword MATCHER ...
Library Highlight (highlight.el) lets you highlight any number of regions in various ways, including using regexps, using any number of faces.
One easy way to highlight an expanse of text (and have it persist until you remove it) is to sweep your mouse over it - like using a highlighter pen. This is command hlt-highlighter. By default, the command is ...

You can set hl-line-sticky-flag to nil
hl-line-sticky-flag is a variable defined in hl-line.el.
Non-nil means the HL-Line mode highlight appears in all windows.
Otherwise Hl-Line mode will highlight only in the selected
window. Setting this variable takes effect the next time you use
the command hl-line-mode to turn Hl-Line mode on.
It's the secondary selection. Clicking and dragging sets the primary selection, and middle click pastes from that selection. Holding alt while clicking and dragging sets the secondary selection, and M-mouse-2 pastes from it. Very few applications use the secondary selection any more, but it's quite handy when you have two things to copy and paste. See ...
highlight-symbol-mode uses text properties, not an overlay.
hl-line-mode uses an overlay, not text properties.
Overlays always take precedence over text properties, no matter how low the overlay priority is.
So without some coding or code tweaking, I don't see a solution.
However, if you use the Highlight library (highlight.el) then the solution is ...
Try M-x whitespace-mode to toggle display of space, line breaks, etc. You can set whitespace-style to control what gets displayed. (Try M-x customize-variable whitespace-style to see what options are available.)
You might also try: M-x customize-group whitespace, to see all the related options -- whether to turn on whitespace-mode globally, how to display ...
Buttons are based on text properties. Each character in a buffer has its own properties. Emacs doesn't record start and end positions for properties: properties are not intervals. When it needs to know where a property starts and ends, it looks for the previous or next change in property. Likewise, buttons don't have a recorded start and end: instead all the ...
There’s no simple variable you can set to control this, but you can do it with some programming if you want.
There is a variable called redisplay-highlight-region-function whose value is a function to be called whenever the region needs to be shown. It creates an overlay that applies the region face to the selection (or moves it to a new start/end positions ...
There are several ways to do this. One of my preferred methods is the bm package. The package provides visual bookmarks:
The setup is dead simple:
(global-set-key (kbd "<C-f2>") 'bm-toggle)
(global-set-key (kbd "<f2>") 'bm-next)
(global-set-key (kbd "<S-f2>") 'bm-previous)
You can change the color of the bookmark with
I did some searching and surprisingly couldn't find any existing minor modes that seemed to do this. I thought it would be a fun little project, however, so I've written a minimal minor mode (rainbow-numbers-mode) that does this and included it below.
As it turns out, the only reasonable way to programmatically set text properties for something like this is ...
Basically, the hl-line face is defining a :foreground property, which is overriding the other foreground colors in your theme.
misterioso defines hl-line in terms of highlight using inheritance, and because of an awkward issue (which I asked about here), it's not possible AFAIK to directly inherit from a face, and override one of the properties to be unset.
I've implemented this for hl-line-mode using the buffer-list-update-hook.
Here's the code:
"Inactive variant of `hl-line'."
(defun hl-line-update-face (window)
"Update the `hl-line' face in WINDOW to indicate whether the window is selected."
(with-current-buffer (window-buffer window)
This should do what you want. Define regexps that match what you want, and faces.
Then match the subgroups in the function you add to font-lock-keywords. The subgroups are used to say that you want only the spaces after indenting tabs, and only non-indenting tabs.
(defface my-tab '((t (:background "LemonChiffon"))) "..." :group 'faces)
(defface my-space '...
This is the case by default for me: hl-line-mode by default uses a face which only specifies a background color. That face is hl-line which by default just inherits from highlight. So maybe the problem is simply your that highlight face specifies both a background and a foreground color. I recommend you M-x customize-face and either change your highlight ...
Are you looking for hi-lock-mode? You can highlight matching regexps or highlight regions by using highlight-phrase: C-x w p phrase RET face RET.
Quoting from the manual:
The kinds of whitespace visualized are determined by the list variable
whitespace-style. Individual elements in that list can be toggled on
or off in the current buffer by typing M-x whitespace-toggle-options.
You're setting whitespace-style with this code:
(setq whitespace-style (quote (face spaces tabs newline space-mark ...
You can use command flash-line-highlight (e.g., bind it to a key) to highlight the current line for line-show-period seconds (which you can customize). This is in library hl-line+.el. See Highlight Current Line.
If you want to highlight both the line and the column temporarily then you can use command flash-crosshairs (bind it to a key). This is in library ...
The problem is that you're trying it out in fundamental-mode. As explained in the docstring of hi-lock-mode:
[...] In buffers where Font Lock mode is
disabled, patterns are applied using overlays; in this case, the
highlighting will not be updated as you type.
so in order for the matching to be done as you type, you need to be using font-lock in that ...
Likely many ways to do this but the built in package called hl-line works very nicely. M-x hl-line-mode works as a local minor mode. or M-x global-hl-line-mode works as a global mode. goto https://github.com/emacs-mirror/emacs/blob/master/lisp/hl-line.el to see more in the comments section.
Another way is to use library Highlight (highlight.el), commands hlt-highlight-symbol-at-point and hlt-unhighlight-symbol-at-point.
They are bound default to C-x X h s and C-x X u s, respectively. All of the highlighting and unhighlighting commands are bound on prefix key C-x X by default. Highlighting commands use prefix key C-x X h. Unhighlighting ...
Read the source code of volatile-highlights and you'll find you don't need advice at all, supporting any command is built into volatile-highlights. All you need is two lines of code:
(vhl/define-extension 'my-evil-highlights 'evil-yank 'evil-move 'some-other-functions ...)
Read the docs for the two functions ...
I realize you asked specifically about org-mode,
but this might be of interest to others reading this.
A general variable exists: mouse-highlight.
Setting it to nil disables highlighting of clickable text in all modes, keeping intact the click function.
It is documented in the emacs manual.
It should work like this: [...] Use cursor keys. Highlighting disappears immediately!
I want show-paren-delay only when navigating the code. If I actually type a new parenthesis, I want immediate highlighting.
You can make it work like that with the following code. show-paren-clear-highlight should be added to Emacs since it's accessing internal ...
In my comment I suggested to use highlight-regexp. But meanwhile I discovered that that method does not keep the highlighting correctly updated (it actually should).
So I wrote up a minor mode hlds-mode that does the job.
I assume that with this minor mode the variable sentence-end-double-space becomes obsolete.
You just only hook the minor mode into those ...
