The easiest way to embed Gists in the WordPress Block Editor
I’m happy to announce the v1.0.0 release of Gistr! Gistr is a WordPress plugin that lets you use the WordPress 5.0+ (Gutenberg) Block Editor by simply pasting the Gist ID into the Block.
Live Demo:
Easy Configuration:

Gistr lets you show or hide the line numbers, hide the Gist footer, highlight lines, and even only show certain lines from any Gist. Future updates will include themes to alter the Gist appearance and the ability to easily change the Gist CSS in the plugin.
Gistr is a WordPress plugin implementation of Gist Embed by Blair Vanderhoof and licensed under the GPLv2 or later license.
Hello! Just wanted to say I stumbled across this when looking for Gist embeds for 5.x, and absolutely love it! One of the few plugins I’ve loved enough to take time and leave a review on the Repo. I did a bit of custom styling, and have a nice dark theme going.
Thank you for this!
