Hop is a programming language designed for the Web 2.0. It is a
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:
