An asynchronous web server written in Emacs LISP

Grant — Mon, 18 Jul 2011 01:45:52 +0000

Elnode is an asynchronous web server written in Emacs LISP.

Emacs has had asynchronous socket programming facilities for some time and a few years ago asynchronous TCP server sockets were introduced. I couldn’t quite believe that no one had written an asynchronous webserver with EmacsLISP before. So now I have.

When I started looking at actually doing this I intended to knock up just a silly demo. But the more I got into it the more it seemed to me that this could be an important addition to Emacs and that, sometimes, an Emacs LISP async web server could actually be useful.

Toggle between Vertical and Horizontal Windows Splitting

Grant — Sat, 15 Nov 2008 04:17:09 +0000

On gnu.emacs.help:

Requested: Function that toggles between vertical and horizontal split layout of currently defined windows preferrably preserving splitting ratio.

(defun my-toggle-window-split ()
  "Vertical split shows more of each line, horizontal split shows
more lines. This code toggles between them. It only works for
frames with exactly two windows."
  (interactive)
  (if (= (count-windows) 2)
      (let* ((this-win-buffer (window-buffer))
             (next-win-buffer (window-buffer (next-window)))
             (this-win-edges (window-edges (selected-window)))
             (next-win-edges (window-edges (next-window)))
             (this-win-2nd (not (and (<= (car this-win-edges)
                                         (car next-win-edges))
                                     (<= (cadr this-win-edges)
                                         (cadr next-win-edges)))))
             (splitter
              (if (= (car this-win-edges)
                     (car (window-edges (next-window))))
                  'split-window-horizontally
                'split-window-vertically)))
        (delete-other-windows)
        (let ((first-win (selected-window)))
          (funcall splitter)
          (if this-win-2nd (other-window 1))
          (set-window-buffer (selected-window) this-win-buffer)
          (set-window-buffer (next-window) next-win-buffer)
          (select-window first-win)
          (if this-win-2nd (other-window 1))))))

Thanks Fabrice.

Color Theme: pink-bliss.el

Grant — Sat, 03 May 2008 22:14:31 +0000

Although pink-bliss.el color theme for Emacs is sure to elicit repressed memories of “Hello Kitty”, the normal confusion about why it exists doesn’t come along with it as you are simply all too lost in the ocean of pink (and pink-compatible) colors.

Color Theme for Emacs

Grant — Sat, 03 May 2008 22:09:27 +0000

Color Theme is an Emacs-Lisp package that lets you create and use different color themes within Emacs.

This is probably critical for anyone new to Emacs.

RLX

Grant — Mon, 21 Apr 2008 00:16:32 +0000

RLX is a rogue-like video game engine written in Emacs Lisp that is being ported to Common Lisp.

In addition to the fact that this is a game so it is just plain fun, the author uses emacs as an IDE for creating games using the engine.
