Ultra Code Fence

Good day everyone. I’d like to introduce you to my new plugin, currently in beta, Ultra Code Fence.

What it does

I love code fencing in Obsidian, but being markdown, it has to follow basic rules. And Obsidian plugins are all about going outside those rules.

As a developer I’ve used the ``` code fencing functionality a lot, but they’re limiting - you get the code, the whole code and nothing but the code.

And they’re totally unsuitable for presenting code output (where you have Prompts, commands, and output).

I found a plugin that did some of this at GitHub - almariah/embed-code-file, but sadly the developer is seemingly no longer supporting it. Initially I did a fork of his code and tried to modify it, but then I wanted more and more features and so I outgrew that plugin.

So, I started again, and behold, I give you Ultra Code Fence!

Some features include:

  • Pull in files from your vault - Reference a script or config file once and it stays in sync

  • Fold long blocks - Show the first N lines with a click to expand (great for lengthy functions you don’t always need to see)

  • Scroll instead of fold - Keep blocks at a fixed height with scrolling

  • Line numbers and zebra striping - Makes reading code much easier

  • Filter by line range or markers - Extract just the bit you care about (lines 50-80, or everything between // START and // END)

  • Style terminal output - Colour your prompts, commands, and output differently

  • Mobile ready - Works on mobile and desktop

Some examples
