Shared Markdown articles and experiments

Article and Experiment use this same Markdown file. Select Experiment on a block to open its interactive workspace. Edit its source locally, then render, copy or download the result

Reusable Markdown

This article includes a fragment from src/content/libraries/authoring-demo.md. Editing that library updates every article that imports it

A second article uses the same library with independent local drafts

Mathematics

Inline mathematics such as $e^{i\pi}+1=0$ and display mathematics share the normal Markdown pipeline

$$X_k=\sum_{n=0}^{N-1}x_n e^{-2\pi i kn/N}$$

Return to the mathematics section resolves its explicit heading ID without a separate link definition

Teaching blocks

One source

An article explains a topic; an experiment exposes its interactive blocks

Reuse a library

Use {{{! library "@library/authoring-demo.md" !}}} to import experiments without duplicating prose

Use a local .md file as a reusable library

Stable block IDs retain experiment selection when the library order changes

DFT is an abbreviation. Highlighted text, x² and Alt+J also render from Markdown

Library

A local Markdown file shared by several articles
