My experience in designing and building websites stretch from making templates for Joomla, Wordpress and Indexhibit to designing and programming full-fledged web-applications from the ground up. As for techniques, I am well versed in CSS, XHTML, JavaScript (including experience in jQuery, Prototype & Scriptaculous and mootools), and I get by in PHP.

These are some free-for-public sites I designed. As you can see I like uncluttered designs.

You can find all of these free Emacs extensions of mine over @ github.

GimpMode

Emacs-GIMP interaction mode. For writing script-fu.

Mingus

My largest program to date. Interfaces mpd, which is a Music Player Daemon. I like to think of it as the Amarok or iTunes for Emacs. Of course there is emms, but I just like to have an overview of my songs.

lisp-magick-doc

Lookup documentation for ImageMagick, an image manipulation toolbox.Handles both C-names and lisp-magick-names

srt-mode

Mode for editing subtitles, using mplayer or VLC as a backend. In development, but usable

nyquist.el

Quite a Spartan elisp library for interfacing the nyquist language format music synthesis and the documentation of nyquist symbols.

poor-mans-bidi

Poor mans mode for editing files with bidirectional text

yiddish.el

Quail input-method for Yiddish

gothic.el

Quail input-method for Goths

The only thing I really hate about JavaScript is the requirement that you put conditions between parentheses.

Format.js This small library implements the function known in other languages as format or (s)print(f).

It makes use of the amazingly powerful String.replace function. That function takes two arguments, the first of which is a regular expression, against which to test. The second can be a replacement string or a function, that receives as arguments the whole match and its various submatches, and that for each match in the string, if you are feeding String.replace a global regexp.

My format function is implemented in a mere 69 lines of code because of that. In its core, it basically is a single invocation of the replace method.

The definition I use for the directives is (how could it not be?) based on the GNUEmacs lisp format function. See the comments in the file for that. Besides that, Format.js comes with a function positionalFormat, which is so neat and small, that I can just show it right here:

function positionalFormat (str){
  var args = arguments;
  return str.replace(/{\s*(\d+)\s*}/g, 
    function(match, num){
      return args[parseInt(num)+1]||match;
  });
};

How to use? Well:

positionalFormat('argument { 1 } '
  + '(or is it { 2 }, or { 0 }?) '
  + 'comes { 1 }',
  3, 'first', 1);

evaluates to: “argument first (or is it 1, or 3?) comes first”. Now ain’t that neat? See how you can reuse arguments?
