Mermaid formatter/linter?

[Yokozuna59]

Hi there! What an amazing tool!

But I've got a question: is there any tool for formatting or linting mermaid code? For both .md and .mmd files.

For example, following some best practices or unwritten rules for making diagrams consistent and so on. Or is there any rule for each diagram to make it better.

It appears that there isn't one yet.

I'm planning to build one here: Yokozuna59/mermaid-lint. Anyone is welcome to contribute and help me! Even thoughts would be fine.

But since there isn't an AST yet (#2523), I'll create it using langium. See #4401 for more information.

Update: The package will be merged in mermaid repo in packages/parser.
