Has anyone written any libraries for elisp to do CGI programming? I threw together a quick first script. However, I'm only a long-time emacs user and I've never really programmed it. When I saw that I could write scripts (--script) in emacs instead of bash, I thought that I would give it a shot. #!/usr/bin/emacs --script (princ "Co...
How can I make SQL queries from within emacs scripts to MySql then print the result set? #!/usr/bin/emacs --script (setq sql "select id, name from foobar order by name ") (princ sql) ...
I'm trying to write a little Emacs Lisp script that reads a csv file from standard input, turns all the rows into a table then prints it to standard out (Unix). I wrote a basic version that takes a csv string and outputs the table to a buffer. However, I would like to turn this into a Unix utility script. #!/usr/bin/emacs --script (...
I was reading subr.el and saw this code: (defalias 'backward-delete-char 'delete-backward-char) (defalias 'search-forward-regexp (symbol-function 're-search-forward)) Interestingly, the first line doesn't use symbol-function while the second line does. The only difference I know of these two ways of using defalias is that the help for...
I recently upgraded to Emacs 23.1.50, and Slime stopped connecting - it would start the inferior-lisp, but never connect. After some investigation, I found that it would work if started from emacs -q and then everything up until and including the call to slime would work. Is there any way to force the remainder of my customizations to ...
In GNU Emacs, I want to run a program, figlet, on the currently selected text. I then want to comment the region which is produced. I have figured out how to do it using the standard Emacs commands: set mark with C-<space> at the start of the word move cursor to the end of the word C-u M-x shell-command-on-region RET figlet RET M-x co...
In GNU Emacs, is there a good way to change the comment-region command in C mode from /* This is a comment which extends */ /* over more than one line in C. */ to /* This is a comment which extends over more than one line in C. */ ? I have tried (setq comment-multi-line t) but this does not help. There is a section on multi-...
In TextMate, one can use ctrl-shift-w to wrap text in an Open/Close tag and ctrl-shift-cmd-w to wrap each line in a region in Open/Close tags. How can I implement this same functionality in Emacs using emacs lisp? emacs becomes <p>emacs</p> And ... emacs textmate vi becomes <li>emacs</li> <li>textmate</li> <li>vi</li> ...
I'm trying to get my Emacs shell to mimic that of my standard terminal sessions. Basically I would like it to respect the same PATH as well as the command prompt. So far I have a few issues: PATH isn't found, below is the fix I'm using for that. I'm getting ascii color codes all over the place with another fix I tried. I have the f...
I have the following emacs lisp snippet that will launch my browser from within emacs and open the specified pages. However when I run it as a script from a shell nothing happens. What more do I need to do? I tried dropping (interactive). #!/usr/bin/emacs --script (defun surf-news () (interactive) (progn (browse-url "http:...
Several times I see ^L in (mostly Emacs Lisp) source codes that looks like are separators of larger logical groups. Is it their real purpose? And if so, how can I use them? Is there a built-in Emacs functionality that utilize it? ...
How can I define an emacs command X that does something and then calls another emacs command Y and also copying the interactive interface of the command Y too? I want to define an altenative version of query-replace with temporarilly toggled value of case-fold-search: (defun alt-query-replace (a b c d e) (interactive) (let ((case-f...
I have not seen a really good example on the web. How can I add authentication to a request like this: (defun login-show-posts () (interactive) (let ((url-request-method "GET") (url-request-extra-headers '(("Content-Type" . "application/xml")))) (url-retrieve "http://localhost:3000/essay/1.xml" (lambda (status) ...
What are some features of Emacs Lisp that you use to solve real problems?

I use the following smart-tab defun in my .emacs for either completion on a word or just to do a standard tab: (global-set-key [(tab)] 'smart-tab) (defun smart-tab () "This smart tab is minibuffer compliant: it acts as usual in the minibuffer. Else, if mark is active, indents region. Else if point is at the end of a symbol, ex...
I'm trying to figure out Elisp, and I've hit a roadblock. I want a function that will Indent the entire file. Right now, I'm selecting the whole file (C-x h) and then doing M-x indent-region (which does have a shortcut key). I'd like to combine that in to a single keypress, but can't figure out how to do C-x h in a function. Thanks ...
I was reading the Simple Database section of Peter Siebel's book Practical Common Lisp with the idea of maintaining a small database of around 50,000 records. I thought doing this in Emacs might be an interesting, and useful, exercise. Emacs Lisp is somewhat compatible with CL except for a few notable differences. The format function ...
Some online websites like to encode all their text through HTML entities, so instead of seeing a text like So I'm looking You get something like: So I'm looking  I was wondering if there's a built in way to translate the encoded text to regular text using any Emac...
It seems one is not supposed to quote KEYMAP when using define-key. (define-key org-remember-mode-map "\C-c\C-r" 'org-remember-kill) I'm confused because I think that all arguments of a function that is not quoted are evaluated, and according to the help, define-key is a function, not a macro. I don't see why the value of KEYMAP can b...
