How to build zig book as PDF on Fedora?

Jakub T. Jankiewicz — Sun, 23 Mar 2025 00:00:00 +0000

I planned to learn Zig Programming Language, and found a Zig Book, but I wanted to read it on my reMarkable tablet, the problem was that officially Zig book is only in HTML format, and don't support building PDF file from source. That's why it's not part of its documentation. But with quarto publishing system, used by the book, it's possible to create a PDF file.

Below is the instruction how to create a PDF version of Zig Book yourself. The instructions are for Fedora GNU/Linux, because this is what I'm using, but building on Ubuntu or different Linux distro should be similar. You only need to find the right package names to install.

How to Implement a Simple Markdown Parser?

Jakub T. Jankiewicz — Tue, 26 Nov 2024 00:00:00 +0000

I've had this idea some time ago to add limited support for Markdown into jQuery Terminal. I decided to use Peggy.js, a maintained fork of the PEG.js parser generator. I already used it for a few projects so I thought it will be the best tool for the job.

PEG is an abbreviation of so-called Parsing expression grammar, a well-known way to define language grammars and create parser generators.

In this article, I will show how to implement a simple Markdown parser to be used with jQuery Terminal. But if you follow along, you should be able to use it for different targets, like HTML.

Hack for Syntax Highlighting of Source Code

Jakub T. Jankiewicz — Wed, 23 Aug 2023 00:00:00 +0000

If you're a web developer, work with JSON data format, and use Google Chrome browser, you have probably seen browser extension JSON Viewer. This extension adds Syntax Highlighting to JSON files viewed in the browser.

I've had a similar idea to display Syntax Highlighting but for JavaScript and CSS files, as part of the website. I just later realized that this is similar to JSON Viewer.

In this article, I will show how I did it and add this feature to my blog.
