I like show-paren-mode in Emacs, but I would really like to change the highlighting behavior for closing brackets. That is, I want the opening bracket to be highlighted when the point is on the closing bracket. The default behavior highlights the opening bracket when the point is on the character following the closing bracket. Is this easy to change? Also, I would be interested in potential benefits of keeping the show-paren-mode behavior as it is.

In Emacs, how can I make a macro, that is local to the HTML mode, and uses dashes and dots? Take a look at the Elisp below: (define-abbrev-table 'html-mode-abbrev-table '(("..." "...") ; won't work ("---" "—") ; won't work ("aaa" "...") ; works ("bbb" "—") )) ; works

I do lots of automatizing in Emacs, by stacking commands that I know from using **manually**. That is a method I recommend, because it doesn't take much effort: you use Emacs as you ordinarily would, and now and then it pops to your head, "hey, I'm always using those commands in succession, why don't I just merge them?" All the more simple since you know the commands, by name or shortcut. One problem, though, is that when you stack commands, you get lots of messages flashing by in the "echo area" (same place as the minibuffer). Those messages don't make any sense, as everything going on below (the functions invoked) is (should be) transparent to the user. So, could you **mute** it, and then **unmute** it? Take a look below: (defun invisible-pretty-mail () "Automatize `pretty-mail'." (interactive) ; (mute-echo-area) (rmail-edit-current-message) (pretty-mail) ; lots of replace-string, replace-regexp, etc. here ; that will flood messages (rmail-cease-edit) ; (unmute-echo-area) ) **Edit** in response to sds' [answer](https://unix.stackexchange.com/a/67191/13136) : I'm very much aware of those notes you refer to, as they are very common in the Emacs help system. While your advice is not incorrect in general, let us examine this particular situation in greater detail: 1) There is an Elisp function in .emacs. 2) It uses commands that the person who setup the function is very familiar with, so it is very readable and maintainable. 3) The function works exactly as intended, with 4) the _one_ drawback that it echos too many messages. Now, in this situation, would you really suggest a **complete rewrite** of that function (and many others), using altogether different commands, commands that may or may not exist, as a possible way of reducing messages, which we won't even know will happen? **Edit**: An example (that works), after the help I got from [Drew](https://unix.stackexchange.com/a/83849/13136) . (defun test-suppress-msgs () (interactive) (let ((log-size message-log-max)) (setq message-log-max nil) (message "This message is suppressed.") (setq message-log-max log-size) (message "This is echoed, and logged.") ))

Similar to org mode, for taking colorful notes in Emacs, I would like to define some special characters (used in the beginning of the lines) to tell Emacs which colors (foreground/background) should be used for highlighting the entire current line. Is there any script for this purpose? If yes, please let me know how I can use it. An example of the notes : # list of operating systems : << highlighted with red @ Unix << highlighted with blue @ Linux << highlighted with blue @ Minix << highlighted with blue

I have started programming scheme, and I noticed the scheme minor mode highlights comments in the most obnoxious way possible when using solarized dark (color-theme-solarized). This also occurs on elisp files. Is there a way I can disable highlighting? It's making the code unreadable.

I'm trying to write a elisp function like this: (setq lst '(("abc" . "c") ("cde" . "f"))) (foo "a" lst) ;=>"c" (foo "b" lst) ;=>"c" (foo "c" lst) ;=>"c" (foo "d" lst) ;=>"f" I know if the first string is same as the key string I can use assoc. (setq lst '(("a" . "c") ("d" . "f"))) (cdr (assoc "a" lst)) ;= "c" (cdr (assoc "d" lst)) ;= "f" I could enable the function by writing the lst separately, but I don't think it's the best way to do. (setq lst '(("a" . "c") ("b" . "c") ("c" . "c") ("c" . "f") ("d" . "f") ("f" . "f") )) Can someone help me how to write the function like foo?

With the following in my .emacs I get narrow margins in text-mode buffers: (defun my-set-margins () "Set margins in current buffer." (setq left-margin-width 30) (setq right-margin-width 30)) (add-hook 'text-mode-hook 'my-set-margins) How can I change the color of the lines that appear to delimit these margins so that it's the same as my background color and not black like they are now? **EDIT** I know more now and this is my question: How do I add a hook to turn of the fringes in text-mode?

How can I tell emacs to run my own script (which can be elisp too or something in Perl, BASH or whatever), and use the next word after the mouse cursor as argument, or maybe using a group of marked words? The output would be in another buffer.

This is small stuff but I haven't been able to figure it out: How do I hide "Mail" from the mode line in emacs?

I'm trying to customize my emacs so that the point color is the same as the foreground on of the character I'm standing on. I have this now: (defun fixpoint () "awesome stuff happening to point" (interactive) (set-cursor-color (eyedrop-foreground-at-point))) (add-hook 'post-command-hook 'fixpoint) I'm using http://www.emacswiki.org/eyedropper.el for eyedropper. There are 2 problems with this I'm trying to fix. First, the hook is ran after each command which seems a bit overkill. Isn't there a hook for point motion? Second, when highlighting matching braces, the point does not change color. I have to move forward to the next matching brace and jump back to see the actual change in point color.

*I'm new to emacs and newer to lisp*

I'm trying to set Meta + spacebar to set the mark for highlighting text (at current cursor position). searching around online and experimenting I've ended up with the command

(global-set-key (kbd "M-SPC") 'push-mark nil nil 1)

The above command isn't working for me though, I'm getting an "incorrect number of arguments error".

Got the function definition,

push-mark &optional position nomsg activate

from elisp manual here

Position: nil for position should default to current cursor position

nomsg: I don't care about (I think)

activate: apparently isn't true by default so I need to set it to...something.

How would I format the command to pass in three values?
*The error is definitely due to the push-mark function call as other functions such as backward-char (which I'm not passing inputs to) work correctly*

I have some code in my .emacs that prevents it from showing some pre-defined special buffers when I'm using previous-buffer and next-buffer: (defadvice next-buffer (after avoid-messages-buffer-in-next-buffer) (when (string= "*Messages*" (buffer-name)) (next-buffer)) (when (string= "*Completions*" (buffer-name)) (next-buffer)) (when (string-match "\*tramp.*\*" (buffer-name)) (previous-buffer)) ... and so on) This works great, but I'd like to have the same functionality for C-x k. So far, I've tried writing the same kind of function (defadvice (after kill-buffer) ...), but that doesn't seem to work. How do I go about doing this?

I could use M-x find-function to find the source code of some elisp functions if the function is not written in C code. But since I am using a **Debian binary package** of Emacs , some of the source code is omitted and only the byte-compiled .elc files preserved. So is there any way to get the source code and attach them with those elc files? Can I use apt-get source emacs and associate with the src (__C code__ as well) with the byte-compiled one. Or do I have to build Emacs from source code?

I use Gnus v5.13 in GNU Emacs 24.1.1 to read my email, and I'm having a trouble getting a simple score file to work. Essentially, I want any mail that's sent to (or copies) a particular email address to be given a higher score. My example score file, in ~/Mail/all.SCORE is: (("from" ("Mark Longair" 1000)) ("To" ("mark-scoretesting@example.org" 1000))) I'm making sure that that score file is being used by having added the following to my ~/.gnus file: (setq gnus-global-score-files '("~/Mail/all.SCORE")) And this does seem to work properly for the rule that matches the From line - matching messages are highlighted, and when I type VS in the summary buffer, it shows a score of 1000 for those messages. However, the "To" rule doesn't match. The [documentation here probably explains this when it says](http://www.gnu.org/software/emacs/manual/html_node/gnus/Score-File-Format.html) : > Scoring can only be performed on these eight headers: From, Subject, References, Message-ID, Xref, Lines, Chars and Date. [Other documentation](http://www.gnu.org/software/emacs/manual/html_node/gnus/Scoring-On-Other-Headers.html) , however, suggest that one can get around this limitation by the following steps: > Put the following in your ~/.gnus.el file. > (setq gnus-extra-headers '(To Cc Newsgroups Keywords) nnmail-extra-headers gnus-extra-headers) > Restart Gnus and rebuild your nnml overview files with the M-x nnml-generate-nov-databases command. This will take a long time if you have much mail. > Now you can score on ‘To’ and ‘Cc’ as “extra headers” like so: I e s p To RET RET. > > See? Simple. Unfortunately, it doesn't seem to be that simple. I've added the following to my .gnus file: (setq gnus-extra-headers '(To Cc) nnmail-extra-headers gnus-extra-headers) ... restarted Emacs, and I've run M-x nnml-generate-nov-databases, but the rule in my score file for the "To" line, still isn't working, even if I type V R to rescore the articles in my summary buffer. Can any suggest why this isn't working?

Is there a way implemented in Emacs to apply a function on a set of files? (Or, if not, do you know of such an extension?) For example, if you have a project in a directory (say, scripts to compile and run, the source, and an XML database). You want to run this function on all those files, one by one: (defun indent-buffer () "Indent the whole buffer according to indent-region-function." (interactive) (indent-region (point-min) (point-max)) ) What complicates the picture at least to some degree, although certainly not impossible, is that Emacs must be in the correct mode to execute such a function sensibly. The coolest interface would be to use Emacs as a server, and then send the command, and the file list, as arguments. Second best if it could be done in Dired.

I couldn't find any instructions on defining key sequences in the Evil doc. The example given by the developers only covers a single key. (define-key evil-normal-state "w" 'foo) What do I need to do, if I want to define "gv" in the normal mode or ";RET" in the insert mode? In Vim, for example, I just do: imap ; ; map gv :tabprev

How do I combine something like query-replace with a regular expression search-and-replace that in part reuses the search result? In my case, how to transform > The programmers are "sort of" confident that the subroutines "load_students" and "compute_student_grade" are without bugs. into > The programmers are "sort of" confident that the subroutines \texttt{load_students} and \texttt{compute_student_grade} are without bugs. I could use two query-replace and then hammer yes and no, but it seems sluggish for a big document. Also, I thought about including the whitespace in the searches (one  " and one " , but that would not work in cases such as ... that's not the way to use "load_students", rather ... Is there built-in stuff for this or do you write Elisp code?

[The Question] *Is there some way to have the pipe/tee/write combo write lines immediately? ... if it can be done, what is the trade-off?* [The Backdrop] My script sends a keypress to the terminal, which is running app. That keypress causes app to write a *marker* to its log. The log is the *app's* normal screen output (timestamped lines). The log is being written via | tee -a log The marker *marks* the line I want; ie. the timestamped line *before* the marker. The problem is that when I then *immediately* search the log (using sed from the same script), it sometimes returns a previous marker, ie. the most recent marker has not been written to the log yet. I assume this is a buffering issue, but I'm in unknown territory with that. Not sure if it matters: The script is elisp. The terminal is emacs terminal emulator with a bash shell.
