Idris2-Jupyter

A Jupyter Kernel for Idris 2.

Installation

Ensure that the Idris 2 Python backend is installed, in a sibling directory of this repository.

Then run:

make install

Running notebooks

Run the notebook as usual, with the built idris2-jupyter module available to the Python module search path.

For example:

PYTHONPATH=build/exec/ jupyter notebook

Note that the cells use the Idris 2 REPL syntax, rather than the syntax used in .idr files.

Importing packages

Additional packages may be made accessible using the .ipkg format. The .ipkg file will be found as though by the --find-ipkg flag, from the working directory.

Plugins

There is a plugin system for displaying rich data responses.

A plugin is a Type in an Idris 2 library which implements the Jupyter.Response Idris2Response and JupyterResponse interfaces. The Idris2Response interface attempts to interpret an Idris 2 REPL response as a rich response. The JupyterResponse interface sends that rich response to a running Jupyter kernel.

Installing plugins

To install a plugin, refer to that plugin's installation instructions.

To install a custom plugin, run make add-plugin with the variables module, plugin, and packages set; then run make install.

The plugin variable is the name of the plugin Type to be used, contained in the module module. The packages variable is a space separated list of packages that need to be imported to use that module. This list of packages is the package defining the named module, and its dependencies, excluding the python and jupyter packages.
