Ignore workspace/didChangeConfiguration #114

Closed joewreschnig closed 2 years ago

joewreschnig commented 2 years ago

Describe the request

The eglot LSP client for Emacs sends the workspace/didChangeConfiguration notification by default on startup (and if configuration changes later).

arduino-language-server currently panics and dies if it receives this notification. However, since it's just a notification and doesn't demand the language server actually do anything, it seems like while unsupported it would be more useful as a no-op rather than a panic.

Describe the current behavior

The server panics when eglot connects and sends workspace/didChangeConfiguration.

Additional context

For anyone finding this and trying to work around the issue, setting eglot-connect-hook to nil will disable the call on startup, but it may still be fired later. eglot-connect-hook is also flagged as a risky local variable which may require changing your enable-local-variables setting to load properly.
