serialization/deserialization for LanguageServer?

[onriv]

Hi during the implementation of customized LanguageServer, some types and messages return from the lsp server end require some specific serialization/deserialization logic (like deserializing to different subclasses)

Any way to do this? Thanks!

If you're interested in how to handle messages about the language server, you can refer to my project, although it is implemented in C#. see: https://github.com/CppCXY/LanguageServer.Framework

@CppCXY Thanks! Checking the source code adding some TypeAdapter to the gson object here may be enough for my use case. Or after deserializing the resp using the default gson object, I serialize it again and then desrialize to my target class.

The use case here is for deserializing some heterogenous json msg from the server like ["a":1, "b":{"c":2}] consisting different types in a list. Gson requires customizing some TypeAdapter for it and I don't know if Lsp4ij has such api or not.

I find eclipse-lsp4j/lsp4j#768 quite similar to my case too. I will give this a try later

@onriv where do you need to convert messages? From data of lsp command? From data of lsp code action? Other?

@angelozerr I am trying to add customizing LanguageServer in the factory

    @Override //If you need to expose a custom server API
    public @NotNull Class<? extends LanguageServer> getServerInterface() {
        return MyCustomServerAPI.class;
    }

and the resp of the api in MyCustomServerAPI requires some customized deserialization. I find that Gson's annotation JsonAdapter seems enough for this and it seems like more related to lsp4j
