CLHP combines the joys of common Lisp with the ease of PHP for web development. Just as with PHP, you embed code into an XML or HTML document using XML processing instructions <?clhp :like-this ?>. By using XML processing instructions, lisp code can be embedded in any valid XML document and still result in a valid XML document
The CLHP parser is integrated into the Apache web server as a module. When Apache recieves a request for a clhp page, Apache passes it on to a Lisp process which simply looks for the <?clhp processing instructions. The Lisp code inside the processing instructions is evaluated, all output through *STANDARD-OUTPUT* is printed in place of the processing instruction block. All other text outside of the processing instructions is passed on as is.
The langauge inside CLHP is Common-Lisp, so CLHP itself defines very few functions. It allows you to build Web programs the same way you would write a Lisp program. You can define functions, structures etc inside your page, or you could load external precompiled files with utility functions in them.top
The latest version is 0.2.0alpha, it brings the Apache module, asdf package building, and a few small enhancements to the CLHP package.top
