I've used [mmdc](https://github.com/mermaid-js/mermaid-cli) to generate mermaid images from a Makefile. It looks like it is implemented with puppeteer, so perhaps it doesn't quite fit your request. But if you just want something you can use at the cli, it is great.

Thanks. You're right, unfortunately this doesn't fit my needs, but I can see how it would be fine for CLI and casual use cases.
