My Jekyll Plugins

Published 2023-05-18.
Time to read: 3 minutes.

This page is part of the jekyll_plugins collection.


All plugins are packaged as RubyGems, and I maintain them on GitHub. The plugins are available as open source under the terms of the MIT License.


To use Jekyll plugins, you must set up a Ruby environment. To learn more about Jekyll, please read my other articles about Jekyll.

The rules for specifying options when using Jekyll tags defined by these plugins are described here.


Many of these plugins were designed with CSS in mind. Some CSS is common between certain plugins. I’ve broken out the CSS into files.

The benefit to you is that regardless of whether you only install one of these plugins or install several, you will have manageable CSS. Each project’s README.md has a section that discusses the CSS files.

Jekyll_plugin_support and Nugem

The jekyll_plugin_support gem is a framework for building Jekyll plugins.

Nugem is a code generator for writing “plain old gems” and Jekyll plugins that are packaged as gems. Nugem uses the jekyll_plugin_support framework.

Most of my Jekyll plugins began their existence as the scaffolding generated by Nugem.
