I only encounter this problem when running Proof General. I'm assuming this is some random minor mode that is started by Proof General, but can't figure out which one! I include a list of minor modes bellow, in case you can recognise the name.
If I place a period in Emacs, the cursor will jump before it, like so:
Writing something|
Writing something.|
Writing something|.
Where | represents cursor and the last two lined happen immediately one after the other.
the same happens if I click at the end of a line with a period. The cursor will appear after the period and immediately jump before the period.
Some sentence. (click here)
Some sentence. |
Some sentence|.
Where the last two lined happen immediately one after the other.
Here is the list of minor modes, in case you can spot the name:
Aquamacs-Autoface Auto-Composition
Auto-Compression Auto-Encryption Blink-Cursor Column-Number Cua
Delete-Selection Electric-Indent File-Name-Shadow Font-Lock
Global-Font-Lock Holes Line-Number Menu-Bar Mouse-Wheel Osx-Key
Recentf Savehist Show-Paren Smart-Frame-Positioning Tabbar
Tabbar-Mwheel Tool-Bar Tooltip Transient-Mark
key binding
--- -------
^C Prefix Command
ESC Prefix Command
. proof-electric-terminator
<C-M-down> pg-move-region-down
<C-M-mouse-3> proof-mouse-goto-point
<C-M-up> pg-move-region-up
<C-S-mouse-1> pg-identifier-under-mouse-query
<C-return> proof-script-complete
(that binding is currently shadowed by another mode)
<M-down> proof-forward-command
<M-up> proof-backward-command
<remap> Prefix Command
... then a bunch of Proof specific minor modes...
Proof General is incompatible with show-paren-mode. You can turn it off with M-x show-paren-mode or by putting (add-hook 'proof-ready-for-assistant-hook (lambda () (show-paren-mode 0))) in the appropriate place in your .emacs.

In emacs-lisp mode whenever i insert a closing brace i prefer to have indented to the same column like the corresponding opening brace. How is that possible? If i have eg in my init.el
(defadvice isearch-forward-regexp (before kill-ring-save-before-search activate)
"Save region (if active) to kill-ring before starting isearch. So that region
can be inserted into isearch easily with C-y."
(when (region-active-p)
(kill-ring-save (region-beginning) (region-end))
) ;; this should be under (when
) ;; this should be under (defadvice
It seems that you want to align the close parens to be able to
visually match them to the opening ones. You can do that with
show-paren-mode instead - it's much better at that job.
As pointed out by others, and I fully agree, the hanging parens are
very annoying and painful to look at - don't make a habit out of using
them. I've authored a minor mode for editing Elisp which might be
interesting for you - lispy-mode:
Pressing i will auto-indent an s-expression, eliminating
the hanging parens.
Pressing d will switch from one side of s-expression to
the other: a quick way to see what the current list contains.
Pressing m will toggle the region selection on the
current list: you can see what it contains even more clearly.
EDIT: Perhaps (in original post) I used the term "transient" incorrectly (I'm not familiar enough with the jargon yet). What I really mean is that the highlighted region will disappear immediately when the user presses a navigation keys eg. arrow-keys... (2nd EDIT: I've removed the word "transient")
The particular issue of selecting a region so the user gets "cursor-key movement will make highlighting disappear" has been the bane of my existance recently. I get differnt results depending on how I run the following script.
Why does it give different results, and more specifically, is there a way to make it produce "cursor-keys make highlighting disappear" regardless of which mode is running, or whether it is being evaluated while testing? .. CUA mode has this behaviour, but I really need that non CUA mode does it too (and eval, if possible)...
Here are the results, followed by the code. (GNU Emacs 23.1.1)
CUA mode enabled
Evaluate via C-x C-e — both (call-trans-hi) and (trans-hi)
NO-GO: Both set mark and move point to EOL, but nothing is highlighted.
Execute M-x call-trans-hi
ok: Works fine; the region is highlighted and then disappears the first time a key is pressed.
Via key binding C-f1
ok: Works fine; the region is highlighted and then disappears the first time a key is pressed.
no CUA mode (pretty much std emacs)
Evaluate via C-x C-e
NO-GO: Same as 1. when CUA is enabled.
Execute M-x call-trans-hi
NO-GO: The line is highlighted, but it is sticky! and requires C-g (keyboard-quit) to clear it.
Via key binding C-f1
NO-GO: The line is highlighted, but it is sticky! and requires C-g (keyboard-quit) to clear it.
;test (trans-hi) EOL
(defun trans-hi ()
"transient highlight"
(beginning-of-line)
(push-mark (point))
(end-of-line)
(activate-mark))
;test (call-trans-hi) EOL
(defun call-trans-hi ()
"call transient highlight"
(interactive)
(trans-hi))
(global-set-key [C-f1] 'call-trans-hi)
When you look at the source of activate-mark, you can see that it's just setting some variables. I suppose that's why you don't see the mark in both 1., because the actual highlighting happens in some stuff that's done when executing functions interactively instead of just calling them.
In the other cases of no CUA-mode, that just how transient highlighting works outside of CUA-mode. If you want the CUA-mode behaviour, use CUA-mode resp. that part of it.
EDIT:
Does this change (the addition of the setq line) to trans-hi make the highlighting work the way you want?
(defun trans-hi ()
"transient highlight"
(beginning-of-line)
(push-mark (point))
(end-of-line)
(setq transient-mark-mode (cons 'only transient-mark-mode))
(activate-mark))
If you want to see the region highlighted when you mark it, you need
to activate the minor mode transient-mark-mode.
When a region is highlighted and a character insterted the default is
to disable the highlighting and insert the character at the cursor.
If you wish you can delete the selected region by activating the minor
mode delete-selection-mode.
I personally keep all lines under 80 characters, but I also work on projects in teams where other programmers don't care about line length.
I love using whitespace-mode, but the long line visualization is really annoying when I'm working on projects where I shouldn't interfere with the long lines. It seems like it should be easy to turn off the long line visualization---I hit m-x global-whitespace-toggle-options l, and then can hit m-x global-whitespace-toggel-options ? to confirm that the "long-line visualization" is turned off. But long lines are still highlighted. I kill buffers and reload them, and highlighting is still there. I'm definitely using global, not local, whitespace-mode.
Why can't I turn off the long line visualization?
The last time I customized whitespace-mode, I noticed that my changes to the settings didn't have any effect in buffers that already existed; try recreating the buffer, or leaving and reentering whitespace-mode. In case you don't already know, you can use M-x customize-group whitespace to turn off that particular option entirely, rather than doing it manually.
Edit: Specifically you want to customize the whitespace-style variable. This lets you turn on and off individual styles. In this case you should turn off the ones labelled "(Face) Lines" and "(Face) Lines, only overlong part". The former changes the face of the whole line when it is overly long, while the latter only changes the face of the part that extends past the threshold.
(Other options in this group define the faces that whitespace-mode will use to highlight the styles you've turned on, the regexes it uses to identify certain situations, etc, but usually you only care about whitespace-style).
Set whitespace-line-column to a higher value (default is 80), so the highlighting of long lines doesn't kick in:
(setq whitespace-line-column 250)
I'm assuming that you already have whitespace-mode activated somewhere in your init.el or similar. If so, you can adapt duma's comment above, and either
Edit the elisp that sets whitespace-style to remove lines-tail. E.g., Emacs Prelude sets
(setq whitespace-style '(face tabs empty trailing lines-tail))
Simply change that to
(setq whitespace-style '(face tabs empty trailing))
If you don't want to directly edit that elisp, but rather override it later with your own code, do something like
(setq whitespace-style (delete 'lines-tail whitespace-style))
Unfortunately, if running Prelude with auto-loaded buffers (using something like Emacs Desktop), the initial setting will take precedence: for each buffer on which you want to see whitespace-style displayed as directed, you must [1]
kill the buffer
re-open the buffer
[1]: Note to OP: if there's another way to reload a buffer, please edit or comment this answer. I was hoping to find something like M-x reload-buffer but am not seeing anything like that with C-h a buffer.
I'm using emacs and auctex to write LaTeX documents. For some reason, M-e doesn't move to the end of the sentence in tex-mode as it did when I went through the tutorial. It moves to the end of the paragraph. (That is, it moves to just before the next double line break)
What is wrong? Do I need to turn on/off some mode to skip to the next full stop? How do I check which modes are active?
I noticed that the same happens in my Emacs. The problem is that the variable sentence-end-double-space is set to t. This means that Emacs expects a sentence to end with a double space. By setting to nil things work properly, i.e., Emacs recognizes a period followed by a single space as the end of sentences.
The first thing to check is what M-e is bound to. In tex-mode, for me, it is bound to forward-sentence. You find this out by C-h k M-e.
It sounds as though it's bound to forward-paragraph, in which case I'd check your .emacs file to see if you've got any overrides in tex-mode hooks, or other things. You can also try running without your .emacs: emacs -q, and seeing what M-e is bound to (to determine if it truly is your .emacs). You can also start without the site lisp file emacs -q --no-site-file - in case your administrators have added anything.
Notepad++ has a convenient feature: if you select a word in your text (not necessarily a keyword), the word is highlighted throughout the text. Can this be done in Emacs as well? And if so, how?
It doesn't necessarily have to work exactly like Notepad++ (i.e., via selection); ideally, I would like to set up a key binding that causes all occurrences of the word under cursor to be highlighted.
It would be great if the highlights were permanent, i.e., moving point away from a highlighted word should not cause the highlight to be removed.
Also, it would be useful if there was a solution that made it possible to navigate between highlights (using custom key bindings).
The hi-lock suggestions are good. I think it's easier to use the M-x versions, though:
M-x highlight-regexp RET <REGEXP>
M-x highlight-phrase RET <REGEXP>
highlight-phrase is just a bit of sugar around highlight-regexp that ignores case and translates a space in the regex to match arbitrary whitespace. Handy.
Maybe highlight-symbol.el at http://nschum.de/src/emacs/highlight-symbol/ is what you are looking for:
Type C-s, then type the current word or type C-w. As a bonus, you can now hit C-s again to search for the word.
This is called incremental search.
What I use is idle-highlight
http://www.emacswiki.org/emacs/IdleHighlight
M-x idle-highlight sets an idle timer that highlights all occurences in the buffer of the word under the point.
To enable it for all programming modes, in ~/.emacs.d/init.el:
;; highlight words
(add-hook 'prog-mode-hook (lambda () (idle-highlight-mode t)))
Light-symbol will highlight whatever symbol point is over.
Alternately, you can use occur, which lists all lines matching a regexp. It's useful to quickly see all functions in a class.
Nobody mentioned symbol-overlay mode. It's basically a better rewrite of highlight-symbol-mode. "Better" as in, lacks bugs of original highlight-symbol (such as, temporary highlight getting stuck, or the temporary highlight disappearing for moving inside the highlighted word; or not being able to highlight symbols like *), better integrated, and maintained. See "Advantages" paragraph of its README.
You can install it as usual, with M-xpackage-install (make sure to update package list beforehand with package-list-packages). For reference, at the bottom I attached code I use to enable the mode and disable a few of the more advanced features which you may or may not want.
Notepad++ has a convenient feature: if you select a word in your text (not necessarily a keyword), the word is highlighted throughout the text. Can this be done in Emacs as well? And if so, how?
Once you enable overlay-symbol, occurrences on the screen will be shown for every word that you put cursor upon after a timeout (timeout by default is 0.5s, can be configured with symbol-overlay-idle-time variable). If a word don't get highlighted, this means there's just one match on the screen (the one you put cursor upon), hence there's no need to highlight it.
It would be great if the highlights were permanent, i.e., moving point away from a highlighted word should not cause the highlight to be removed.
To highlight the word under cursor permanently there's a function symbol-overlay-put. To unhighlight call it once again.
In my config example it's bound to Logo+` key.
(require 'symbol-overlay)
(defun enable-symbol-overlay-mode ()
(unless (or (minibufferp)
(derived-mode-p 'magit-mode)
(derived-mode-p 'xref--xref-buffer-mode))
(symbol-overlay-mode t)))
(define-global-minor-mode global-symbol-overlay-mode ;; name of the new global mode
symbol-overlay-mode ;; name of the minor mode
enable-symbol-overlay-mode)
(global-symbol-overlay-mode) ;; enable it
(global-set-key (kbd "s-`") 'symbol-overlay-put)
(setq symbol-overlay-ignore-functions nil) ;; don't ignore keywords in various languages
(setq symbol-overlay-map (make-sparse-keymap)) ;; disable special cmds on overlays
This may not be as nice as what you were hoping but if you put
(global-hi-lock-mode 1)
in your .emacs file then you can type C-x w h REGEX <RET> <RET> to highlight all occurances of REGEX, and C-x w r REGEX <RET> to unhighlight them again. Again, not as elegant as you'd probably like, but it'll work.
Try http://www.emacswiki.org/emacs/msearch.el
All occurences of the text selected with the cursor are highlighted.
You have to drag over the string which you want to highlight. That enables you to easily change the selection without changing the highlight.
If you want to preserve the highlighting of a string you can freeze it.
You can enslave a buffer to another buffer. Text selected in the master buffer will also be highlighted in the slave buffer. That is useful for comparing buffers.
It is also useful for taking notes in one buffer while you investigate the text in another one. You can have a collection of keywords in the notes buffer. Drag over such a keyword and its occurences in the investigated text will be highlighted.
I am using this stuff for years now. I added the freezing quite recently. So, maybe something is broken. If this is the case leave me a note on http://www.emacswiki.org/emacs/msearch or here.
Check Interactive Highlighting
Should be:
C-x w h word <RET> <RET>
Try iedit. It highlights the word at point and lets you edit all occurrences of it easily. With an additional keystroke (C-'), it hides all the lines without that word in it. Very handy!
Commands in library highlight.el
let you (un)highlight text matching a regexp (in this case a symbol), using overlays or text properties. You can cycle among the occurrences. Highlighting can be temporary or persistent. (more info).
This maybe won't highlight but will search for a word without you needing to type it...
when you've reached the word you wanted to search, C-S, then read the full word with C-W then you can C-S and it will search for it. In my Emacs it also highlights all instances in the document.
This package available in Melpa works, you can customize the highlight style as well.
