JCAT

jcat is a self-contained command line tool for viewing jupyter notebook files in terminal. It parses notebook's underlying json content, hence it runs without the dependency of jupyter/ipython core.

Most systems with g++ and make installed should be fine.

Looking for easier installation? Checkout the python implementation.

Build and Install

Clone this repo, if you want to be able to easily uninstall jcat use checkinstall.

sudo apt install checkinstall
cd jcat
sudo checkinstall

Otherwise, you can use make to install.

cd jcat
make
sudo make install

Optionally, one could use ./jcat without runing sudo make install;
or use make install PREFIX=/path/to/install for alternative installation directory (by default is /usr/local, which puts jat into /usr/local/bin).
