Polyglot features

Available language kernels

Python 3

Polus Notebooks use `ipython language kernel <https://github.com/ipython/ipykernel>`__ for Python

Current version of Python installed is 3.7.3. Python packages are managed with conda package manager. You can use both conda or pip to install and update new packages

R

Polus Notebooks use `irkernel language kernel <https://github.com/IRkernel/IRkernel>`__ for R.

Julia

Polus Notebooks use `IJulia language kernel <https://github.com/JuliaLang/IJulia.jl>`__ for Julia

Java

Polus Notebooks use `IJava language kernel <https://github.com/SpencerPark/IJava>`__ for Java

Octave

Polus Notebooks use `octave_kernel language kernel <https://github.com/Calysto/octave_kernel>`__ for Octave

C++

Polus Notebooks use `xeus-cling language kernel <https://github.com/QuantStack/xeus-cling>`__ for C++

Bash

Polus Notebooks use `bash_kernel language kernel <https://github.com/takluyver/bash_kernel>`__ for Bash

Scala

Polus Notebooks use `almond language kernel <https://almond.sh>`__ for Scala

Javascript

Polus Notebooks use `IJavascript language kernel <https://github.com/n-riesco/ijavascript>`__ for Javascript

Typescript

Polus Notebooks use `ITypescript language kernel <https://nearbydelta.github.io/itypescript/>`__

Polyglot notebooks

Script of Scripts (SoS) enables communication between multiple language kernels in the same notebook. That means that you can create notebooks which will have a code in multiple languages working together, i.e. you can read document using Python, run data analysis in Java and visualize results in R.

Create polyglot notebook

To create Polyglot SoS notebook, click SoS icon in launcher

Variable exchange

SoS extends Jupyter with more magics commands like %command. Here we show the two most important commands: %put and %get.

#Create variable in Python
x = 42

%put x
#Share variable with SoS for ither languages to use

%get x
#Read variable from R

42

See SoS documentation for more details
