About HH-Web

HH-Web is the beginnings of a web application framework written in Lisp designed to streamline development of modern web applications.

* Features *

In its present form (as of August 2010), there are 4 principle features in hh-web:

  * Custom tags: HH-Web let's the developer write a web page using convention Lisp s-expression syntax, completely 
  with properly generated CSS & Javascript.  More importantly, commonly used fragments of HTML/CSS/Javascript
  can be bundled as a tag (just like HTML tags such as p, div, h1, etc.), and the corresponding HTML/CSS/Javascript
  for the expected fragment will be generated instead.  Using custom tags means that most of the development of a new
  site involves the common elements that make up the pages, creating custom tags (with parameters or "attributes", when 
  necessary), and then authoring the pages as templates using both HTML tags and the site-specific custom tags.

  * 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.
