DSL auto-formatting

[torsten-systemticks]

Hi @simonbrowndotje,

is there somewhere in the structurizr world a library/interface to (programmatically) auto-format / pretty-print a DSL file ?
I would like to integrate such a feature into my language-server.

Thanks,
Torsten

@torsten-systemticks that discussion, where we talked about using Antlr4 or something similar, was based on my desire to have the same feature.

I was planning to develop some kind of prettier plugin to be able to format Structurizr DSL files in all IDEs that prettier is supported.

But all Prettier examples that I found require an AST Parser. :S

Nothing that I know of, although I did come across this -> https://github.com/Colin-TUE/prettier-plugin-structurizr

Unfortunately nothing in your own Java libraries...
But thanks anyway.

The implementation you mentioned uses the typescript variant (chevrotain) of Javas ANTLR...

@torsten-systemticks are you still planning to embed the auto-format feature in your vscode plugin?

I don't know if there is a simpler strategy to do that, but I have found a basic implementation of the same algorithm that prettier.io uses, but this one uses Java.

Yes, I think I will provide some kinde of auto-format feature.
Thanks for sharing the link to that library. I will have a look, if it is suitable.
