Web Application Development in PLT Scheme

Many users often post to the plt-scheme mailing list asking for introductions to Web application development in PLT Scheme. They've heard of the continuation-based PLT Web Server and want a gentle introduction. Unfortunately, there has been a distinct lack of good documentation and tutorials for the server. Taking the cue from two users: Jens Axel Soegaard and David Reynolds, we've written a tutorial with Danny Yoo.

The tutorial is available at http://docs.plt-scheme.org/continue/index.html. It walks through the creation of a blog application, introducing features slowly and culminates in an SQL-backed database for the posts. Of particular interest, is the fast start servlet setup based on the Instaservlet package from Untyped.

Please take a look and pass along this as a pointer to those who may be interested in PLT Scheme.

Notable changes:

• misc: mzc can "decompile" bytecode files; `#lang' lines wired to the top of DrScheme's definition window; improved searching in DrScheme; some foreign interface extensions.
