This is my first time including snippets of the video in the article like this, let me know what you think! ## examples ``` bash 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 ``` ![running jut examples](https://images.waylonwalker.com/jut-command.gif) ## 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. ``` bash jut --help ``` There is some good information on the projects [readme](https://github.com/kracekumar/jut) as well. ![getting help with jut](https://images.waylonwalker.com/jut-help.gif) ## without installing _using pipx_ Don't want jut cluttering up your venv, or want to save yourself from making a new one, [`pipx`](https://github.com/pypa/pipx) can manage a separate virual environment for you. This is one of the biggest selling points for me. ``` bash pipx run jut https://cantera.org/examples/jupyter/thermo/flame_temperature.ipynb --head 3 ``` ![running jut with pipx](https://images.waylonwalker.com/jut-pipx.gif) ## 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`. ``` bash pip install nbconvert ``` > nbconvert does not have its own cli, instead it sits under the jupyter command. ### converting to html > Need to see images, go here! ``` bash wget https://cantera.org/examples/jupyter/thermo/flame_temperature.ipynb jupyter nbconvert flame_temperature.ipynb --to html python -m http.server ``` > Note, nb convert does not work with a url, you will need to have the notebook locally. ![nbconvert to html to see images](https://images.waylonwalker.com/jut-nbconvert-html.gif) ## what other options does nbconvert offer? `nbconvert` also offers a standard help flag that you can access by passing in the `--help` flag ``` bash jupyter nbconvert --help ``` ### 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. ``` bash jupyter nbconvert flame_temperature.ipynb --to maarkdown cat flameflame_temperature.md ``` ![nbconvert to markdown and displaying in bat](https://images.waylonwalker.com/jut-nbconvert-markdown-bat.gif) ### 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 ``` ![nbconvert to markdown and displaying in glow](https://images.waylonwalker.com/jut-nbconvert-markdown-glow.gif) ### viewing markdown as slides with lookatme _[lookatme](https://github.com/d0c-s4vage/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. ``` bash lookatme flameflame_temperature.md ``` ![nbconvert to markdown and displaying as slides with lookatme](https://images.waylonwalker.com/jut-nbconvert-markdown-lookatme.gif) ### 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`. ``` bash pip install rich python -m rich.markdown flame_temperature.md ``` 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`](https://github.com/pypa/pipx) to manage the installation sandbox for you. ## Links * [jut](https://github.com/kracekumar/jut) - View notebooks in the terminal * [nbconvert](https://nbconvert.readthedocs.io/en/latest/usage.html) - convert notebooks to other formats * [flame-temperature notebook](https://cantera.org/examples/jupyter/thermo/flame_temperature.ipynb) - The sample notebook I used * [glow](https://github.com/charmbracelet/glow) - Terminal Markdown viewer * [lookatme](https://github.com/d0c-s4vage/lookatme) - Terminal Markdown slideshow tool * [pipx](https://github.com/pypa/pipx) - Run python cli's without maintianing a virtual environment * [rich](https://github.com/willmcgugan/rich) - Beautiful python terminal formatter
