ANN: HOP-1.9.0
Manuel Serrano
higher-order language for programming interactive web applications
such as web agendas, web galleries, music players, etc. Hop can be
viewed as a replacement for traditional graphical toolkits. HOP is
implemented as a Web broker, i.e., a Web server that may act
indifferently as a regular Web server or Web proxy.
HOP features:
* a versatile Web server supporting HTTP/1.0 and HTTP/1.1,
* an optimizing native code compiler for server code,
* an on-the-fly Javascript compiler for client code,
* an extensive set of widgets for programming fancy and portable
Web GUIs,
* a native multimedia support for enabling ubiquitous Web multimedia
applications.
* fast WebDAV level 1 support,
* an extensive set of libraries for the mail, calendars, databases,
Web technologies, ...
HOP is available at:
The release 1.9.0 is a major release. It highlights are:
* new linguistic forms (e.g., "comet" server events).
* new APIs (e.g., multimedia, cryptography, ...).
* new implementations (e.g., new fast Web server scheduling,
new support for keep-alive connections, new compilation
techniques, ...).

weblets easily available on Web) which is now able to automatically generate
web pages.

A web2.0 virtual desktop complete with games and a Scheme REPL! :)

What am I missing?
From the REPL:
:=> (define factorial2
(lambda (n)
(if (= n 0) 1
(* n (factorial2 (- n 1))))))
#<procedure hash-3>
:=> (factorial2 5)
*** [object Error]

It seems the REPL is limited, you can't define globally, just inside
lets.
Anyway, it looks like a very good web framework for creating fluid
web2.0 rich interfaces by means of server-side compiled Scheme.
