I like diagrams that live close to the code they explain. An exported image is easy to forget, difficult to review, and usually out of date after a few changes.
That is why I built compiles on the server and shows the result as you type. The covers the grammar, components, math labels, output modes, framework adapters, and Markdown integrations. The source is available on GitHub.
A note on scope
Version 0.2.0 is a foundation, not a claim that every engineering or UML notation is already present. Some symbols and diagram semantics are still missing, and dense automatic layout remains hard work. I would rather be clear about that and improve it with real examples than hide the limits behind a broad promise.
Contributions are welcome, especially for missing symbols, adversarial routing cases, UML notation, accessibility, and browser rendering differences. If a change affects the grammar, please open an issue first so we can keep the language coherent and the compiler within its size budget.
I built Schemd for my own technical writing and engineering tools. I hope it also makes your diagrams easier to maintain.
