How to template out JSON in Bash

I have three different text editors, that I use for three distinct use cases.

I’m a software developer, so I basically edit text files for a living, and the editing software that I use for this is fairly important to me.


For any substantial editing, either for work, or for personal projects, I currently use Visual Studio Code - generally known as “vscode”. It’s good enough: it’s extremely actively developed, so always up to date, and it has all the plug-ins you could ever want. Performance is good enough, once it’s started up.

I tend to just start my project editor once and leave it open permanently.

I’m still aggrieved that Microsoft killed the Atom editor when they bought GitHub, despite promising that they wouldn’t. It was a better editor - better UX, Tree-sitter, etc …

Tag Icon in the shape of a luggage tag
Figure 1. This pages tag list is using this tag icon from FontAwesome. This is a 550 byte SVG file, 346 bytes gzipped.

If you want to use SVG icons on a website and style them with CSS - then the SVG needs to be inline - i.e. the SVG markup needs to be included with the rest of the pages HTML markup.

Unfortunately putting things inline means that they can’t be cached. In this article I’ll show one way to get around this - and get the best of both worlds: inline styleable SVG icons, with caching!

How to find a git repositories default branch name

Two screenshots of the nginx Welcome page, side-by-side, showing the page before the change and afterwards. The one on the left is dark-on-light and the one on the right is light-on-dark.
Figure 1. The nginx “Welcome” page, before & after my intended change.

I wanted to add dark mode support to the default nginx “Welcome to nginx” page. This is about the simplest change I could choose to make - it’s a simple, backwards compatible, small additive change to one single index.html file. My initial version of this change looks like this, and is added to the files <style> element, in the <head> section:

@media (prefers-color-scheme: dark) {
  body {
    background-color: #363839;
    color: #d1cec9;
  a {
    color: #c4c4ff;

So, this is the process of getting that change from my brain, into the upstream nginx codebase.

cssmin is unmaintained & has a bug with complex :is selectors

Sometimes I want to have a just a tiny bit of CSS that’s unique, just for one page or post. I don’t want a whole stylesheet, or to have to add this to my site-wide theme, just for one post – I want a simple way to add it in the post itself.

This is how I did it:
