Most of the personal static content I want to put on the Internet. Built with Pelican.

Development

Install and use pre-commit git hooks.

Install the requirements:

pip install -r requirements.txt

Install the TailwindCSS CLI. I recommend installing it as a standalone executable:

curl -sL https://github.com/tailwindlabs/tailwindcss/releases/latest/download/tailwindcss-macos-x64 -o tailwindcss
chmod +x tailwindcss

PyInvoke will expect the tailwindcss executable to exist in PATH. Personally, I keep executables for my user in ~/.local/bin/ and add this to PATH. Mirroring the full Unix root structure is useful if you need to compile binaries just for your user.

List and use the PyInvoke commands:

inv --list

Theme

I'd like to just inherit the simple theme, but they don't wrap everything in block so I can't customize as much as I want. This means that some settings in the docs won't work because I removed the places the variables are read.

All non-blogpost files (including index.html) will be generated from the page.html template. All blogpost files will be generated from the article.html template. This means we don't need an index.html template.

Styling

I'm using TailwindCSS. We're using it as a PostCSS plugin. PostCSS is some way of combining JS and CSS. I've got this input file called tailwind.css. tailwind.config.js knows where our HTML content lives; when I run a TailwindCSS CLI command to convert the PostCSS input file to a CSS output file, Tailwind will only add styles that our HTML is actually using to the output file. This keeps our output file very small!

Design Showcase

Inflation-adjusted prices

I try to display inflation-adjusted USD prices by using the Urban Consumer Price Index Minus Food and Energy.This was inspired by Gwern.

Client-side lookup: The inflation calculation is done client-side instead of during build because:

• I want the display to be up-to-date even if I don't build the site every year. Performing the calculation client-side means I can look up the current year and just display the original price and original year if my CPI data is outdated.
• It's slightly more general: building the website periodically to update inflation is assuming that inflation is fairly slow-moving.

Interoperability with Markdown: I've written a Python-Markdown extension to swap $[price:year] with <span class="inflation" data-value={price} data-year={year}>${price} in {year}</span>, which the JS snippet can then operate on. The extension contextualizes the price, so it's useful even if JS is disabled, my snippet has a bug, or the CPI data is oudated.

Design Graveyard

Embed Jupyter Notebooks

It'd be neat to use a plugin to embed Jupyter Notebooks in blog posts. The main problem is that making the Notebook CSS play well with our site CSS wasn't straightforward, and while I could use some hacks I didn't want to depend on a static nbconvert version (nbconvert chooses the CSS version). I can revisit this if there's more documentation and stability around Jupyter Notebook CSS classes.

Alternatively, I could convert to Markdown and then style the input/output cells myself. I didn't want do that.
