LeftParen

LeftParen lets you make web apps quickly.

LeftParen 0.61 is a PLT Scheme web app framework. LP is in its early stages, and I need your help to improve it. Please contact support@leftparen.com with any questions, suggestions, or ideas. The documentation is pretty limited at this point, so please don't hesitate to email me with even the silliest of questions.

LeftParen 0.3 released--compatible with PLT 4.1

Tonight I released the next version of LeftParen. The major change in this version is PLT 4.1 compatibilty. Note that it is not backwards compatible with earlier versions of LeftParen. There are a bunch of new features in this release too. Unfortunately, none of them are documented (that’s next on the todo list!). But, the tutorials have been updated, so make sure to check them out. As always, feel free to email with any questions.

I’d also like to announce that the source for LeftParen is now available on github.

Features

Automatic creation of the basic directory structure of your project
A "Hello, World" with zero lines of code
Simple data persistance storage through the "record" abstraction
No databases or schemas
Session and cookie support
User accounts and authentication out-of-the-box
Easy form creation
Simple URL mappings (like Rails' routes)

Acknowledgements

LeftParen was written by Rob Hunter but it builds heavily on (and, in fact, often directly incorporates) the work of Untyped (instaservlet and dispatch), Jens Axel Soegaard (web.plt), and, of course, PLT Scheme.
