We are very happy to announce the release of the version 2.0 of the Ocsigen framework. After more than 6 years of development, we achieved our goal to provide a complete framework to program Web sites and client/server Web applications fully in OCaml. More information and download from http://ocsigen.org Main features: - Powerful mechanisms to implement traditional Web interaction very easily (links, forms, bookmarks, back button ...). - A compiler from OCaml to Javascript to write the client side parts of your programs in OCaml. - Integrated client/server programming in one single program, with automatic communication between server and client. - Validation of HTML at compile time. - Powerful session mechanism - Persistant client side programs: you can mix client side features with traditional Web interaction. The program does not stop when you press a link! The documentation is now mostly complete. We are currently working on adding the few missing parts and proof reading everything. Current version is available online and a more polished version will be released as a PDF book in a few weeks. The good starting point for learning Ocsigen is the tutorial: http://ocsigen.org/tutorial/ Please report any problem with current version or in documentation through the bug tracking system, the mailing list or the IRC channel. The Ocsigen framework combines many software projects (all open source), that can be used independently: - Ocsigen server: an extensible Web server - Eliom: a framework for Web programming in OCaml - Js_of_ocaml: a compiler from OCaml bytecode to Javascript - Lwt: a cooperative threading library - Macaque: a library for type safe database queries - O'Closure: a binding for the Google closure widget library - etc. The full list of our projects is available here: http://ocsigen.org/projects Ocsigen is a research project of the PPS laboratory (CNRS, université Paris-Diderot) (http://www.pps.jussieu.fr), hosted at IRILL (http://www.irill.org). It receives funding from the ANR (PWD project) (http://www.agence-nationale-recherche.fr). We hope that you'll enjoy this version! Vincent Balat [for the Ocsigen team]
