Prism on a CDN

This is something I didn't know about: Prism, the syntax highlighter I use, is available from a few free CDN's, so I don't have to host it. Cool!

A programmable color scheme

I'm not a designer, and I've never been happy with the color scheme for kavanot.name, so I decided to try something new. I use scssphp with scssphp server (and yes, you need both) to generate the CSS, and it allows variables, so I can do: $hue = 250; $saturation = '40%'; $textcolor: hsl($hue, $saturation, 10%); […]

Implementing the History interface

The way browser history is implemented, with the History interface, is useful for other things than site navigation. The same idea, basically an extended stack that allows going back and forward, is the same algorithm used for undo/redo, and command line history. It would be nice to be able to do const h = new […]

Moving bililiteRange into the modern age.

I haven't updated bililiteRange for years, but it's time to drop support for Internet Explorer and use modern constructs like Promise and input events. It should make things more simple. From here on in, I will only support Chrome, Firefox and Edge (the chromium-based one; I don't have Edge Legacy. I'm also working on moving […]

Extending Parsedown: attributes

Markdown Extra (including Parsedown Extra) allows for attributes to be applied to certain elements: headers, fenced code blocks, links, and images. I'd like to be able to apply them to any element. I'm going to use the syntax of Python Markdown attributes, but the attribute lists go before the elements. For block level elements, they […]

Extending Parsedown: Block elements

Continuing work on extending Parsedown. See the actual code. Adding block-level elements is not much different from adding inline elements. Kavanot.name originally used <footer> elements to indicate the source of a block quote: <blockquote> Do or do not. There is no try. </blockquote> <footer>Yoda</footer> </blockquote> While marking blockquotes this way is now acceptable, for a […]

Extending Parsedown: Inline elements

Extending Parsedown involves adding elements to the $InlineTypes and $BlockTypes arrays, then adding methods to handle them. See the actual code. Italics I use <i> a lot, to indicate transliterated words. So I use could use "/" to indicate that: /Shabbat/ is a Hebrew word becomes <i>Shabbat</i> is a Hebrew word. To do that: do […]

String Replacement in PHP

Working with Parsedown, I want to string manipulation but only in certain parts. For instance, on text not in HTML tags or not in quotes. The right way to do that is with a real parser. The easy way is by removing the unwanted strings, replacing them with a marker that won't come up in […]

Extending Parsedown

I've been spending all my intellectual free time on working on my Kavanot site, so I haven't been doing any independent programming. But that site uses raw HTML, which is a pain to type. So I decided to start using Markdown to make writing easier. After a little trial and error, I decided to use […]

H&R Block Updating Errors

(It's been almost a year since I've posted. My intellectual life is busy with other things) I use H&R Block software to prepare my taxes and have been generally very happy, but this year it would not update the program after January 1. Using the automatic update downloaded the updater but it silently failed. Manually […]
