IOCaml is an OCaml kernel for the IPython notebook. This provides a REPL within a web browser with a nice user interface including markdown based comments/documentation, mathjax formula and the possibility of generating all manner of HTML based output media from your code.

This repository hosts the iocamljs-kernel package.
With this kernel the OCaml REPL is compiled to JavaScript and run in the browser.
The demo notebook js_of_ocaml-webgl-demo.ipynb provides a good example of what
can be done. Its an almost direct copy of the
js_of_ocaml WebGL demo except
the 3d model, shader code, ocaml code and html code are all embedded in the notebook
and can be compiled and run live in the browser.
When run using the IOCaml server the
toplevel can support file I/O including dynamic loading of libraries using
topfind #require directives.
$ opam install iocaml
or to just get the kernel
$ opam install iocamljs-kernel
Precompiled versions which can be used with the Enthought IPython distribution on Windows can be downloaded from here.
