A Jupyter kernel for Scilab.

Project description

A Jupyter kernel for Scilab

Prerequisites
-------------
`Jupyter Notebook <http://jupyter.readthedocs.org/en/latest/install.html>`_, and `Scilab <http://www.scilab.org/download/latest>`_.

Installation
------------

pip install scilab_kernel

To use it, run one of:

.. code:: shell

ipython notebook
# In the notebook interface, select Scilab from the 'New' menu
ipython qtconsole --kernel scilab
ipython console --kernel scilab

This kernel is based on `MetaKernel <http://pypi.python.org/pypi/metakernel>`_,
which means it features a standard set of magics. For a full list of magics,
run ``%lsmagic`` in a cell.

A sample notebook is available online_.

You can specify the path to your Scilab executable by creating a ``SCILAB_EXECUTABLE`` environmental variable. Use the ``scilab-adv-cli`` executable if using a Posix-like OS, and ``WScilex-cli.exe`` if using Windows.


Configuration
-------------
The kernel can be configured by adding an ``scilab_kernel_config.py`` file to the
``jupyter`` config path. The ``ScilabKernel`` class offers ``plot_settings`` as a configurable traits.
The available plot settings are:
'format', 'backend', 'width', 'height', and 'resolution'.

.. code:: bash
cat ~/.jupyter/scilab_kernel_config.py
# use Qt as the default backend for plots
c.ScilabKernel.plot_settings = dict(format='svg')


Troubleshooting
---------------
If the kernel is not starting, try running the following from a terminal.

.. code
python -m scilab_kernel.check

Please include that output if opening an issue.


Advanced Installation Notes
---------------------------
We automatically install a Jupyter kernelspec when installing the
python package. This location can be found using ``jupyter kernelspec list``.
If the default location is not desired, you can remove the directory for the
``scilab`` kernel, and install using `python -m scilab_kernel install`. See
``python -m scilab_kernel install --help`` for available options.
