IOCaml

======

IOCaml is an OCaml kernel for the 

[IPython notebook](http://ipython.org/notebook.html). 

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.

* [IOCaml-server](https://github.com/andrewray/iocamlserver)

This repository hosts the iocaml-kernel package.

# Installation

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

```

# Running

Simply run iocaml from the command-line. This should automatically start the iocaml web interface and open a browser window 

```

$ iocaml

```

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 `In [*]`. 

## Jupyter

The kernel can also be used with the IPython/Jupyter server.

* [IPython](https://github.com/andrewray/iocaml/wiki/ipython_install) 

* [Jupyter](https://github.com/andrewray/iocaml/wiki/jupyter)

**Note:** To use IOCaml with the latest IPython/Jupyter notebook, you'll need to start it with `--Session.key=''`:

```

jupyter notebook --Session.key=''

```

This disables some security measures that iocaml doesn't yet support.

## Command line options

The following options may be given to the IOCaml-kernel (via

the IPython profile config) or IOCaml-server.

* ``` -log  ``` open log file

* ``` -init  ``` load ```file``` instead of default init file

* ``` -completion ``` enable tab completion

* ``` -object-info ``` enable introspection

The following option is for use with IPython

* ``` -connection-file  ``` connection file name
