Sharing a Plugin for Mermaid Diagrams in Pelican

[NoelJames]

Hi there, I just wanted to share a plugin I wrote that might be useful to others.

It’s called Merlican, and it adds support for rendering Mermaid diagrams in Pelican content. It processes fenced ```mermaid blocks and converts them at build time.

You can find it here:

The plugin follows Pelican’s namespace plugin structure (pelican.plugins.merlican) and includes setup instructions in the README. Once installed, you just need to add "merlican" to your PLUGINS list in pelicanconf.py.

Important: You’ll also need to enable the fenced_code extension in your MARKDOWN settings, or the plugin won’t detect the Mermaid blocks correctly. There’s a short snippet in the README that shows how to do this.

Here is a simple demo
