failed to create the popup/phantom (during "signature help" request of LSP)

[rwols]

Indeed, there are some hints in the console:

LSP:      {'activeSignature': 0, 'signatures': [{'label': 'parse(llvm::yaml::MappingNode *Params, clangd::Logger &Logger) -> llvm::Optional<WorkspaceEdit>', 'parameters': [{'label': 'llvm::yaml::MappingNode *Params'}, {'label': 'clangd::Logger &Logger'}]}], 'activeParameter': 0}

Hope this helps!

Mdpopups version?

[rwols]

>>> import mdpopups
>>> mdpopups.version()

You need to upgrade your dependencies. Despite what is claimed, Package Control does not often update dependencies as it should. You are pretty far behind.

[rwols]

Strange, I'm pretty certain I upgraded last time I had this problem.

Package Control: The dependency 'mdpopups' is installed, but out of date; upgrading to latest release 3.1.3 from 2.2.0...

Anyway, I still have no highlighting at the moment. But that's okay. You can close this if you want.

[facelessuser]

What do you mean no highlighting? Did you restart after upgrade?

[facelessuser]

Also, you can download this package https://github.com/facelessuser/mdpopup_test.

Run the basic test (look for the Mdpopups commands in the palette). Don't bother with the UML command as that requires other installation. If that pops up okay, then we are good. I support mdpopups directly, and my packages that use it, but I don't directly support LSP as that is not my package. They may be doing something wrong.

[rwols]

Yes, we had this exact same conversation a while a go. Perhaps it's a regression in LSP.

This should in principle have highlighting from a syntax file:

I just figured out the problem; the languageId is set to c-family but it should be set to objc++. I remember that this got fixed but maybe something went awry during the great refactor.

[facelessuser]

Cool, so it's a LSP issue, right? If so, feel free to close this issue.
