In this very meaty episode of Programming By Stealth, Bart Busschots teaches us how to build data structures using jq with JSON files. We're not just querying existing data, we're rebuilding the data the way we want to see it. We learn how to build strings with interpolation, which I find is a very odd word to describe the process. It's really like concatenation in Excel, but maybe that's just me.
We build arrays using jq, and even convert between strings and arrays with the `split` and `join` commands. We build dictionaries in a syntax that is simple and elegant. We also build dictionaries from strings using `capture` with Regular Expressions.
We learn not to do string formatting and escaping using `@` – for example `@csv` can automatically create comma-separated values data for us and @uri can escape characters for us in a URL we build using jq.
Like I said, it's a meaty episode but Bart and I both enjoyed the lesson quite a bit.
You can find Bart's fabulous tutorial shownotes at pbs.bartificer.net. And just in case I forgot to mention it earlier, remember that we now have transcripts with chapter breaks. This means you can jump pretty easily to a topic to reread exactly how Bart explained something. You even get a time stamp of when he talked on that subject, allowing you to easily skim to the portion of the audio you want to rehear for clarification. All thanks to the magic of Auphonic. Ok, it's not magic, but it _feels_ like magic!

More from Programming By Stealth
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.
