Welcome ... I'm Kristof

I've been a passionate software developer for a very long time ... now I'm a tech-savvy IT manager and tinker with things like this blog in my free time ;)

Developing software never lets you go. It's a creative passion and for me it's the web that has fascinated me for almost 30 years.

My latest stuff is below and here is more about me. Meet me @kiko@indieweb.social.

Extension of downupPopup: Back Button, Escape Key & More

Contributing to Ali Dinçer's Bottom Sheet project

I recently introduced a Bottom Sheet dialog on this blog to display a page’s metadata (like this), using Ali Dincer’s work: downupPopup. I described the way to do this in a post a couple three weeks ago.

Shortly after that Koos Looijensteijn triggered me with his post How to make digital business cards and share them via QR codes and I felt like using my newly introduced dialog manager based on downupPopup for my own contact card.
But more about that at a later time, respectively blog post…

Important for this post is that Ali’s bottom sheet solution did not offer everything I wanted for my implementation:

1. Make Dialog Reusable

As I have already described in the above mentioned article: Ali’s approach to calling the dialog was to create and initialize the necessary HTML elements if it didn’t already exist in the DOM. I pulled out the initialization to make the component reusable. There is now a preparation part and an initialization part and the latter is always called, no matter if another bottom sheet dialog was already created before.

Include and provide JSON data in Hexo EJS Templates

... with a new Helper and an async function

The three main components of a standard installation of the Static Site Generator Hexo are the template system EJS (Embedded JavaScript Templating), Markdown for the content and Stylus for the styles.

In the template files are the three main tags for driving content:

Scriptlet tag for control flow (no output)

1
2
3
<%
... my JavaScript code to process data into the template
%>

Output a value as escaped HTML

1
<%= myVariable %>

Output of a raw value, usually in the form of a JavaScript function

1
<%- myFunction() %>

Hexo’s helper system is based on the latter. So you can include a JavaScript file in your template that makes use of the JS Helper in node_modules\hexo\lib\plugins\helper\js.js as follows …

1
<%- js('/js/dist/myFancyFunctions.js') %>

… which will be rendered to:

1
<script src="/js/dist//js/dist/qr-code-styling.js"></script>

The Problem

So far and short, so good … but I recently tried to use this way to include a JSON file whose data one of my scripts needed as startup options and I noticed that the above mentioned JS helper unfortunately takes care of the possibly missing file extension js. It doesn’t matter if you only pass the path to the file as a string or if all necessary attributes as an object.

Show pages meta data (JSON-LD) in Bottom Sheet

Visualize the generated meta code on your page in a sliding panel for review and information purposes

A few months ago I introduced new meta data (JSON-LD) for the pages of this blog and also wrote about my implementation. Works also everything quite well … only the verification of the generated data was a bit cumbersome:

  1. Open DevTools for a page in Chrome.
  2. Search in the HEAD of the source code for the included script (“application/ld+json”)
  3. Copy out JSON-LD code
  4. Format JSON into VS code … and check

Nothing for now and simply impossible on the smartphone, even if there would be a reasonable Chrome extension for displaying JSON-LD data, but it does not exist (yet). Another problem was that I use automatically generated Socal Media images for my articles, which are included in the JSON-LD, but do not appear anywhere in the page and thus were beyond my control. I simply wanted to display all the generated stuff.

Since I’ve been a fan of the so-called bottom sheets since the first version of Google’s Material Design, I imagined a script that grabs the code embedded in the page and pushes a panel with all the data visualized there into the page from the bottom … and the whole act was easier than I thought.

Top 10 Pens of Jon Kantner

A while ago I posted my favourite pens of 2022. Many of them came from the pen of John Kantner and that was reason enough for me to highlight his most beautiful works in a post.

My “Best of Jon Kantner” selection is focused on the usefulness for UI’s to be created, i.e. all these things I urgently need to try out or one or the other will end up in one of my projects.

Breton Presets for Lightroom

‘Le Bretagne’ (Brittany) is one of the most beautiful and historic parts of Europe and always worth a visit. It combines the sometimes rugged English flair with the art of living of France, both scenically and in the architecture and the way people live there. My wife likes all things English and I am a friend of the french ‘Savoir Vivre’, and we were able to combine the two beautifully on a trip to Saint-Malo and Jersey. It was a photographers dream…
