Access to serializer/deserializer?

[PatrikN-work]

Hi,

I'd like to use the langium as a serializer/deserializer for my semantic model , more specifically my GLSP semantic model.

Is there a (simple) way to access the langium serializer/deserializer "backend" programatically?

Hey @PatrikN-work,

you should be able to use the JsonSerializer service that performs both serialization and deserialization of AST models. Note that it's currently limited to references to elements that live in the same document.

Thanks for a quick anwer!

Sorry, I wasn't clear in my question. I want to serialize according to my Langium grammar not in json format (which I interpert that the JsonSeralizer does).

[PatrikN-work]

Sorry, again I was unclear. I need seralization as well as deserailization.

Langium will have deserialization, I assume?

Thanks!

With deserialization you just mean a parser, right? Langium of course provides a parser, given that it's a language engineering framework.

To be specific, Lexing and Parsing. Going from text to AST.

Is is possible to "hook into" that today and how?

[msujew]

Yes, you can just call the LangiumParser service of your language container:

Great, thanks. I'll give it a try.

And please prioritize the serializer as well :-)
