@alcarney @tombh I did not see a test for workspace symbol, this change updates existing support for workspace symbol to enable resolve if "workspaceSymbol/resolve" is implemented.

[tombh]

Great, thank you. It looks like a pretty straightforward change. Just needs a rebase of main and we can get this merged?

[karthiknadig]

@tombh re-based to main.

[tombh]

Damn, needs rebasing again! Busy day for that pygls/capabilities.py file, which is great 💪

Also, does this contribute to the LSP 3.17 support as well? Outlined in #346

[karthiknadig]

@tombh Yes this covers the symbol resolve.

Great 🎉 Thank you.
