Tagmatter

Automatically formats inline #tags into clean YAML frontmatter.

What it does

Write tags anywhere in your document using the standard #tag syntax, and Tagmatter will automatically format them into your frontmatter. For anyone who prefers using tags throughout their writing, or simply doesn’t want to fuss with YAML, Tagmatter keeps your metadata clean by collecting every inline tag and properly formatting it in frontmatter automatically.

Example:

You write:

"#Luke, you can destroy the Emperor. He has foreseen this. It is your destiny. Join me, and #together, we can rule the #galaxy as father and son."

Tagmatter automatically creates/updates:

---
tags:
  - galaxy
  - luke
  - together
---
