How to use this for a Plack app? #35

Closed tomascohen closed 4 years ago

tomascohen commented 4 years ago

It is not clear in the docs how to bind the server process to the language server .

I haven't tried this but here's my guess.

You could try the launch.json mentioned in https://github.com/richterger/Perl-LanguageServer/blob/master/docs/Perl-LanguageServer%20und%20Debugger%20f%C3%BCr%20Visual%20Studio%20Code%20u.a.%20Editoren%20-%20Perl%20Workshop%202020.pdf

And then create the launch.json as specified in https://code.visualstudio.com/docs/editor/debugging

Obviously modifying the launch.json to be for the app you're looking to debug of course

minusdavid commented 4 years ago

Actually, after reviewing that first document again, I have no idea

minusdavid commented 4 years ago

Yeah no I think that is it. Visual Studio Code probably sends the launch.json info through the debug port that Perl::LanguageServer is listening on, and then I imagine Perl::LanguageServer creates a child process that runs the desired program to debug.

Yes, this is how it works. So you need to start your Server by LanguageServer. This will work, as long as your server is a Perl program. This is because the Perl code needs to be started with debug options, otherwise the debugger don't get the necessary information from the Perl interpreter.
