I just published a new small and focused frontmatter parser. I feel like existing ones are too outdated and/or try to do too much.

The frontmatter pagination of this book I’m reading is driving me mad.

The @biomejs.dev YAML parser now passes the official testing suite. 100% code coverage.

This means you'll get formatted code in the Markdown frontmatter.

The fact that an LLM wiki standard is “markdown with yaml frontmatter” - which has been human hand built without a CMS for years - is kind of amusing.
I think this is actually a very good idea, and LLM-Wiki is genuinely a very good discovery that can be standardized. The idea of a *portable* knowledge base in this format opens up modes of use we simply have not fully explored.

With Obsidian Bases, your data is backed by your local Markdown files and properties stored in frontmatter. To support the new query capabilities, we're introducing the .base file format and syntax.

w3c static site generator with yaml-ld frontmatter

I think could be done with `llm` and some YAML frontmatter! 🤔
Is there an standard or something like that to represent a conversation with an LLM in Markdow? System Prompt, Model, Config, User Input, Model Output, ...

I'd love to have an easy way continue a conversation stored on a Markdown file (that can be updated / modified).

Great post!

Code likes structured data. LLMs like unstructured text. Markdown with structured frontmatter is the ideal both-worlds format of the future

Some other great ideas there too

Fancy Bluesky buttons for everyone!

No need to store @standard.site rkeys in your YAML frontmatter – just derive them from your existing URL paths.

another small addition to my website: a scrolling marquee of pinned folders/pages in the nav bar — i just set “pinned: true” in a page’s frontmatter and it appears there

Built a prototype Vite plugin for importing markdown:

- Based on unified/remark/rehype
- Supports Shiki via rehype plugin
- Framework agnostic
- Zod schema for frontmatter

Here's the API:

flat files are nice for portability and “markdown is nice” reasons

but everything other than content really needs to in a DB instead, YAML frontmatter is so silly

Huge thanks to @marcoroth.dev for turning around this Herb feature request on the same day I made it. You're a true honey badger (laudatory). 😁 🧡

Comark can now:

🪓 parse Markdown with frontmatter, attributes and components support

🎇 render it at runtime, with @vuejs.org, @react.dev, @svelte.dev and now @angular.dev support

Soon we'll open source Comark CMS, the content layer on top of it, framework-agnostic 🔥

I once wrote hyperbolically that all the important answers in life are found interspersed in books on close-up magic. But perhaps I should add that some insights are also to be found in the frontmatter of origami books.
