Trying to read a .ipynb file without starting a jupyter server? jut has you covered.

install

jut is packaged and available on pypi so installing is as easy as pip installing it.

pip install jut
Enter fullscreen mode Exit fullscreen mode

examples

jut https://cantera.org/examples/jupyter/thermo/flame_temperature.ipynb
jut https://cantera.org/examples/jupyter/thermo/flame_temperature.ipynb --head 3
jut https://cantera.org/examples/jupyter/thermo/flame_temperature.ipynb --tail 2
Enter fullscreen mode Exit fullscreen mode

what are all the commands available for jut?

Take a look at the help of the jut cli to explore all the options that it offers.

jut --help
Enter fullscreen mode Exit fullscreen mode

There is some good information on the projects readme as well.

without installing

using pipx

Don't want jut cluttering up your venv, or want to save yourself from making a new one, pipx can manage a separate virual environment for you. This is one of the biggest selling points for me.

pipx run jut https://cantera.org/examples/jupyter/thermo/flame_temperature.ipynb --head 3
Enter fullscreen mode Exit fullscreen mode

nbconvert

jut is the lightweight option that I think will fit the bill often for me, but it just doesn't always cut it. Mostly if there are images in the notebook or large output that is hard to read, its time to pull out the medium guns that sit between fulling running jupyter and jut.

pip install nbconvert
Enter fullscreen mode Exit fullscreen mode

nbconvert does not have its own cli, instead it sits under the jupyter command.

converting to html

Need to see images, go here!

wget https://cantera.org/examples/jupyter/thermo/flame_temperature.ipynb
jupyter nbconvert flame_temperature.ipynb --to html
python -m http.server
Enter fullscreen mode Exit fullscreen mode

Note, nb convert does not work with a url, you will need to have the notebook locally.

what other options does nbconvert offer?

nbconvert also offers a standard help flag that you can access by passing in
the --help flag

jupyter nbconvert --help
Enter fullscreen mode Exit fullscreen mode

converting to markdown

nbconvert also supports converting to many other formats, one option that is quite interesting for use in the terminal is markdown. We could simply convert the notebook to markdown and cat it out.

jupyter nbconvert flame_temperature.ipynb --to maarkdown
cat flameflame_temperature.md
Enter fullscreen mode Exit fullscreen mode

viewing markdown with glow

Glow is a terminal markdown viewer that looks really good. These days I use bat as cat so I don't get quite as much benefit from glow, but it still looks pretty good.

glow flameflame_temperature.md
Enter fullscreen mode Exit fullscreen mode

viewing markdown as slides with lookatme

lookatme

Lookatme is my slideshow tool of choice. Creating slides in markdown is such a fantasic user experience, It realy lets you go from outline to finished slide deck fluidly. Refactoring the whole thing is also so much easier than with gui tools. Once you have your idea fleshed out it does make the process of making slides in powerpoint much easier if thats what you need.

On to nbconvert, without even changing the notebook we can look at the notebook as a slideshow in the terminal. The only thing that it needs is some markdown headers to start new slides from.

lookatme flameflame_temperature.md
Enter fullscreen mode Exit fullscreen mode

viewing markdown with rich

Bringing this full circle, lets take a look at the converted markdown with rich. Here you will notice a surprising similarity to what we saw with jut.

pip install rich
python -m rich.markdown flame_temperature.md
Enter fullscreen mode Exit fullscreen mode

Rich still cannot pull directly from a url or display markdown with out being installed and managed by yourself. Unlike how jut can leverage pipx to manage the installation sandbox for you.
