"ERROR: Message 'open' not understood": when opening schelp file from Help Browser #25

[prko]

Thanks for the fix for https://github.com/scztt/vscode-supercollider/issues/25 I am now experiencing the following problem:

ERROR: Message 'open' not understood.
Perhaps you misspelled 'new', or meant to call 'open' on another receiver?

Unfortunately, this is a limitation of the language server right now: there's not a clear way for a language server to tell the client (e.g. VSCode) to open a document. This can be fixed, but it would need a mechanism outside of the regular Language Sever Protocol API.

If anyone can find an existing API that might be appropriate for telling a client to open a file, I can try to hook it up: https://microsoft.github.io/language-server-protocol/specifications/lsp

Oh! Of course, I just found it :) https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#window_showDocument

Added an enhancement ticket for this, so I'll close this one. https://github.com/scztt/LanguageServer.quark/issues/16

Most of this work was already done, but there was one small piece missing. This should be resolved in the latest vscode visx, but if it is not I can post a new build that has the fix.

Thank you very much!!!
