This notebook is a demonstration of some of capabilities of fastpages with notebooks.
With fastpages you can save your jupyter notebooks into the _notebooks folder at the root of your repository, and they will be automatically be converted to Jekyll compliant blog posts!
The first cell in your Jupyter Notebook or markdown blog post contains front matter. Front matter is metadata that can turn on/off options in your Notebook. It is formatted like this:
# Title
> Awesome summary
- toc: true- branch: master- badges: true
- comments: true
- author: Hamel Husain & Jeremy Howard
- categories: [fastpages, jupyter]toc: true will automatically generate a table of contentsbadges: true will automatically include GitHub and Google Colab links to your notebook.comments: true will enable commenting on your blog post, powered by utterances.More details and options for front matter can be viewed on the front matter section of the README.
A #hide comment at the top of any code cell will hide both the input and output of that cell in your blog post.
A #hide_input comment at the top of any code cell will only hide the input of that cell.
In [2]:
#hide_input
print('The comment #hide_input was used to hide the code that produced this.')
put a #collapse-hide flag at the top of any cell if you want to hide that cell by default, but give the reader the option to show it:
In [4]:
#collapse-hide
import pandas as pd
import altair as alt
put a #collapse-show flag at the top of any cell if you want to show that cell by default, but give the reader the option to hide it:

stocks = 'https://vega.github.io/vega-datasets/data/stocks.csv'

Charts made with Altair remain interactive. Example charts taken from this repo, specifically this notebook.

You can have footnotes in notebooks, however the syntax is different compared to markdown documents. This guide provides more detail about this syntax, which looks like this:
{% raw %}For example, here is a footnote {% fn 1 %}.
And another {% fn 2 %}
{{ 'This is the footnote.' | fndetail: 1 }}
{{ 'This is the other footnote. You can even have a [link](www.github.com)!' | fndetail: 2 }}{% endraw %}For example, here is a footnote {% fn 1 %}.
And another {% fn 2 %}
{{ 'This is the footnote.' | fndetail: 1 }} {{ 'This is the other footnote. You can even have a link!' | fndetail: 2 }}
