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 iocaml-kernel package.
Installation requires opam and OCaml >= 4.01.0. To use the OCaml server
$ opam install iocaml
which will install the kernels and server. The individual kernels can be instaled with
$ opam install iocaml-kernel $ opam install iocamljs-kernel
Simply run iocaml from the command-line. This should automatically start the iocaml web interface and open a browser window
When opening a new notebook,an iocaml-kernel process should be automatically started. For example enter
let a = 12 + 30, hit ctrl-enter, and you should see the response
val a : int = 42.
Note that starting up the kernel might take a while the first time, during which your input prompt will look like
The kernel can also be used with the IPython/Jupyter server.
Note: To use IOCaml with the latest IPython/Jupyter notebook, you'll need to start it with
jupyter notebook --Session.key=''
This disables some security measures that iocaml doesn't yet support.
