I've added a simple basic authentication mechanism to the Factor web server (called 'httpd'). Basic Authentication is built into all browsers so it makes for a simple authentication method. It has one major downside and that is the password and username are sent from the browser to the client in clear text. You can work around this by using SSL... more →

This matches an object against a pattern and constructs a new object given a second pattern. The second pattern can use pattern matching variables from the first pattern... more →
I've added some code to the Factor parser combinator library to allow search and replace using parser combinators. The idea was to be able to do similar things with parser combinators that regular expressions are commonly used for. I've also started adding some simple reusable parsers for numbers, strings, etc. The search word takes a string and a parser off... more →
I've added support to fjsc for cross domain AJAX calls to web services that use the JSON format. Usually Ajax requests from a web page are limited to requesting resources on the server that the web page originated from. A way to work around this is to load cross domain Javascript by creating an HTML SCRIPT tag dynamically, setting the... more →

Namely the 'callcc0', 'callcc1', 'continue' and 'continue-with' words. This involved quite a few changes to the internals of the compiler. The Javascript generated code is now in continuation passing style (CPS). It makes the generated code harder... more →
