MarkEdit Sort Text Extension

I recently discovered MarkEdit, an open-source Markdown and text editor for macOS. It is intentionally minimal and fast, but I missed one small feature: sorting text, either a selection or the entire file. So I wrote an extension to add it.

The project has a well-reasoned philosophy that aims to keep the app very simple. There are options for customization, text processing using macOS system services, and extensions.

I used Claude Code to help me write a simple extension for sorting text, either a selection or the entire file. It’s a small thing, but was a fun and useful way to learn how to add to MarkEdit.

Source code: bcantoni/markedit-sort-text: Sort text extension for MarkEdit editor

Project page (install extension from here): Sort Text for MarkEdit

After installing the extension, you can add sort up/down icons to the toolbar by following the Toolbar icon setup steps.

MarkEdit continues to be my daily text editor at home and work. I’ll likely find new ways to extend it and was happy to find it was so straightforward. My small fix here isn’t big enough to be on the official MarkEdit Extensions list yet, but maybe some day :)
