21.1. Drawing the Game Board Using the SVG Format

We’ve already written a primitive web server in Chapter 13. Also, we’ve covered how to draw SVG graphics with a DSL in Chapter 17. Lucky for us, the new HTML5 standard includes features that make it possible to embed SVG pictures directly inside a standard HTML document. In this way, we’ll be able to use our simple little web server to serve up some fully interactive vector graphics. You’ll be amazed at how easy it is to do this.

Note:

At the time this book was written, the only web browser to support inline SVG within HTML was Firefox 3.7 Alpha. Use this, or a more recent release of Firefox with our new version of Dice of Doom. If you’re having problems, try navigating to the about:config page in the Firefox address bar, and set the html5.enable configuration setting to true. This will allow Firefox to use the latest HTML5 settings.

Also, remember that our web server library is not pure ANSI Common Lisp, and makes use of some CLISP-specific extensions. This means it requires CLISP to function.
