The Ocsigen project already includes Eliom, a web programming framework for the Ocaml language. Eliom provides a solid and extensive foundation for building highly dynamic sites. Litiom aims to complement Eliom, offering higher-level modules codifying a number of common patterns found in web sites. (The name of the project comes from the fact that Lithium follows Helium in the periodic table of elements).
Presently, Litiom includes two modules: Litiom_blocks and Litiom_wizard. The former is based on the realisation that many web sites are composed of fairly independent boxes arranged in a hierarchy. With Litiom_blocks, the user provides the contents for each box, together with its relation to other boxes in the web site hierarchy tree. The module automatically takes care of spawning Lwt threads in such a way that independent branches of the tree are executed in parallel. As for the latter, it aims to simplify the construction of sites relying on wizard-like interactions. It is based on the fact that most wizards follow a fairly repetitive pattern.
Litiom is developed by Dario Teixeira and is licensed under the GPL 2.0.
Litiom is distributed in source-code form. It uses
Ocamlbuild
as its build system (Ocamlbuild is included with Ocaml 3.10),
and relies on Findlib
being installed. Simply type make to build it and
make install to perform a Findlib installation.
To build the API documentation type make apidoc.
Note that it depends on the Ocsigen and Lwt libraries.
Download version 1.0: litiom-1.0.tgz (2009-04-14)
You can browse the Ocamldoc generated API documentation online. Note that it is assumed that the reader is comfortable with the Lwt and Eliom libraries.
