elisp

问题 I am pretty new to elisp, and i was trying to define a function to set highlight behavior while searching. The goal is: after i-search , I want to be able to clear the highlight with C-g , but I want the highlight to remain if I press enter. So i defined a function in my init.el as: (defun keyboard-quit-cleanup () "clean up highligh after keyboard quit" (keyboard-quit) (lazy-highlight-cleanup)) (global-set-key (kbd "C-g") '(keyboard-quit-cleanup)) how-ever, it doesn't work. What's wrong here?

问题 I am trying to resize the occur-mode buffer window to fit the contents of its buffer. See Resize occur window in Emacs for more information. I have added the following hook: (add-hook 'occur-mode-hook (lambda () (save-selected-window (pop-to-buffer "*Occur*") (message-box "ok") (fit-window-to-buffer nil 10)))) Then I have the following buffer window: and I now execute (occur "test") which gives me first and after pressing the "ok" button I get Notice that the occur window has shrunk to a

问题 I'm reading a bunch of MySQL files that use # (to end-of-line) comments, but my sql-mode doesn't support them. I found the syntax-table part of sql.el that defines /**/ and -- comments, but according to this, Emacs syntax tables support only 2 comment styles. Is there a way to add support for # comments in sql.el easily? 回答1: Emacs-24 sql.el has this built-in! Simply run M-x sql-set-product MySQL RET and the syntax table is set up automatically, as are the font-lock-keywords for all the

问题 I am unable to access remote files in my usual way: C-x C-f [server]:[path][file] and am thrown this error: Wrong Type Argument: listp, [[server]:[path][file] I'm not even sure how to debug this further. any help is appreciated. edit: output when trying to debug: Debugger entered: nil (progn (debug) (ido-mode t) (progn (ad-add-advice (quote completing-read) (quote (foo nil t (advice lambda nil (if (boundp ...) ad-do-it (setq ad-return-value ...))))) (quote around) (quote nil)) (ad-activate

问题 In Elisp, I've encountered different APIs for modeling boolean values. I was under the impression that t and nil were the idiomatic ways of representing true and false respectively. However, I've also seen 1 and -1 used to model the same thing. What confuses me is that I have come across APIs that won't work if nil is supplied but will work if -1 is used. Can someone help me understand which is in fact the preferred way. And if the answer is t and nil , I welcome any theories on why some

问题 I'm tired of emacs clobbering my windows with its output, and unpredictably at that. I'd like to have several windows in emacs frame and have each window dedicated for a certain purpose only. For example, ECB panels | Editor 1 | Editor 2 | Bookmarks+ ------------------------------------------------ "Messages" (output buffer) So, when I run M-x compile , I want the output to always go into Messages. Similarily, when I run M-x magit-status , I want results in Messages, as well. Clicking on a

问题 I'd like to create additional regular expressions for use with etags, but I'd like them to be based upon what's already there (in particular, I'd like to add [ \t]* to the current set of regular expressions that etags uses). What are the default set of regular expressions that etags uses for .lisp files? 回答1: etags doesn't generally use regular expressions to implement the languages that are built-in. Instead, it has custom parser code for each built-in language. That said, it seems for Lisp

问题 I have electric-pair-mode on (which isn't really particularly relevant, as this could apply to any auto-pairing mode or even manual parens), but in a nutshell, I'd like it so that in the case I have: function foo() {|} (where | is the mark) If I press enter, I would like to have it automatically go to function foo() { | } It would also mean that function foo(|) {} would become function foo( | ){} I already have things to take care of the indentation, but I'm not sure how to say "if I'm inside
