In this week's installment of Programming By Stealth, Bart Busschots teaches us how to use jq as a programming language. Before we get into the new stuff, Bart takes us through his solution to the challenge, and I have to say I was pretty chuffed when he said my solution to the extra credit portion was more elegant than his. To be fair, it took a buddy programming session with him for me to get the _first_ part of the challenge figured out.
When we got into the programming language part of the lesson, there were so many times that I said, "I needed this last week!" I think finding out these options are available after understanding the problems they solve was fantastic.
We learned how to run jq filters from files, which means no more looking at our filters all on one line - we can put line feeds and indents into our filters to make them more readable. We can even add comments. Bart tells us about a couple of handy plugins for VS Code to give us syntax highlighting which will be swell.
My favorite thing I learned was how to add debugging to our filters. This one is a life changer. We explore a few functions for exploring data filters that will make life easier. We wrap up with an introduction to jq variables, which the developers of jq really don't want you to use unless absolutely necessary.

We dust off our memory from where we left off learning about Jekyll back in PBS 181 in June of last year. After some housekeeping, Bart takes us through the challenge solution from PBS 181, and then teaches us how to add metadata to our static sites. After the new material, he sets up where we're going next in learning how to organize our content with Jekyll taxonomies. He even explains what the weird term "information architecture" means in this context.
In this final episode of Tidbit 19, Bart walks us through the very few libraries he used for the final design of his Linkifier CLI App. His choices on tooling to build nice terminal commands and provide color in the terminal (like red for error messages) were based on simplicity, the fewest dependencies, and active support. It was a very fun episode to record as he wrapped the entire story up in a bow.
We're back with Part B of Tidbit 19, where Bart walks us through the architecture of his Linkifier module. He starts with the three data modeling classes that he's been using for decades, but explains how hard it is today to extract article headlines. He walks through how he developed an extraction logic but had to do it per domain. That sounds crazy but he uses surprisingly few sites for his articles for Security Bits and Let's Talk Apple.
In Part A of Tidbit 19, Bart explains the problem he needed to solve, which was bringing a script he's written up into the modern age as a JavaScript command-line interface app that can help navigate the AI landscape. As always, his explanation is geared towards teaching us the fundamentals with his problem as the example.
One of the things that helps your posts get traction is if you have a nice, pretty card that displays when you post the URL on social media. Plain blue links just don't get clicked. With WordPress and other dynamic Content Management Systems (CMSs), you can get plugins to create the pretty cards. But with Jekyll (and Hugo and other Static Site Generators), you need to build the capability into your theme. It's not hard, you just need to know what metadata to build, and of course, Bart is here to teach it to us.
