- Features *
In its present form (as of August 2010), there are 4 principle features in hh-web:
Regex-based URL dispatching: Inspired by Django's use of regex dispatching, HH-Web implements a similar technique, but in Lisp. Most importantly, if the regex contains "variables" (e.g., named registers, in regex parlance), then symbols will be interned for those variables and exposed as parameters to the URL's handler. Thus, components of an URL's path will automatically be extracted and made available as arguments to the handling code.
Dynamic code reloading: While not implemented for every aspect of hh-web (e.g., URLs), for tags and templates, changes in the underlying code is by default automatically reflected the next time the page is refreshed in the browser. The intent is to provide the equivalent usability of other web authoring environments such as PHP or ASP: change the code for a page, and reflect that immediately in the browser.
Integrated caching: HH-Web's support for caching is evolving, but in its current form it permits marking caching guidelines for specific URLs. Specifically, caching causes HH-Web to preseve any generated content (from templates and tags, typically) in an in-memory cache for later use. If a request for a page in its map appear again, then HH-Web will serve the content from the cache, rather than invoking code to regenerate the content fresh.
