Debugging language server remotely about xtext-languageserver-example HOT 12 CLOSED

please check the startup script created by gradle.
i asusme code in extension ts is old/outdated/unrelated

or use the socket mode. there you can start the server from eclipse in debug mode

i also wonder if you need to configure something client side for didChangeWatchedFiles

i usually write a delegae message consumer here
return result;
instead of returning the original one.
you might be able to do the same for the io server

Thanks. I am not sure what "socket mode" would be. Are you referring to something like this: https://github.com/itemis/xtext-languageserver-example/blob/master/vscode-extension/src/extension.ts ?

If yes, would that mean that I would need to also change gradle to launch the client differently from the RunServer type?

There are several startup scripts, my.namespace.mydsl.ide.bat, mydsl-socket.bat, mydsl-standalone.bat
They all use %XXX_OPTS% amongst others when running java, but I don't see where to set this property... I could set it manually, I guess.

So, is my understanding correct that this function is not having any effect?

Sorry, I am not following why a delegate like this would be needed and where I would put it, not sure what "io server" means.

from xtext-languageserver-example.

result = new MessageConsumer() {consume(message m){ consumer.conume(m)}}

from xtext-languageserver-example.

language servers can task to client via
java socket
process io
websocket

i dont know how the api that calls the gralde script from typescript set the options or not.
you would need to alter the script and debug

from xtext-languageserver-example.

when i debug RunServer with the vscode-extension(this one uses socket) then i see didChangeWatchedFiles called

from xtext-languageserver-example.

=> how did you customize the languageserverimpl

from xtext-languageserver-example.

I might have just misunderstood when this message is sent. It is send when the user changes what file is opened or in viewport, or when exactly?

public class MyDslLanguageServer extends LanguageServerImpl {

	private static final Logger LOG = Logger.getLogger(LanguageServerImpl.class);
	@Override
	public void didChangeWatchedFiles(DidChangeWatchedFilesParams params) {
		super.didChangeWatchedFiles(params);
		// trying to log some message here
	}
}

Could you help me once more in how I would go about if I want to debug the RunServer with a vscode-extension as well. I pretty much followed the setup of this repository setting up my projects.

from xtext-languageserver-example.

Okay, my original understanding was that this message is sent when the "watched" files change, i.e. if a file of extension ".mydsl" is edited in the client. Reading the spec again, I think my original understanding is correct. So, that is actually what I would like to be notified about in my server.
Also, can I configure what files my extension is watching?

from xtext-languageserver-example.

i guess this is something to ask in the languageserverprotocol and or vscode languageclient repo.
i dont get the edited point.
edits you will get notfied with didChange

i dont know what your debugging problem is. cant you simply edit the script and hard code remote debugging there? (or use the socket client + server as proposed, started in debug mode from eclipse (or idea))
i have no idea where you exactly are stuck
