Hi @H-G-Hristov . Would it be possible to provide an isolate repro? Using just the code you provided, I was unable to reproduce an issue.

[H-G-Hristov]

@Colengms I am getting another strange issue in the same project:

It looks like a different extension is trying to render the documentation comments. This is my status bar in the same project as above:

In this project I have CMake, Python, Shellscript, Swift (Xcode) code and Objective-C.

Please note the anomaly between these two screenshots:

[H-G-Hristov]

@Colengms Please note how "Swift" appears in the namespace:

This could be related also to the following issue I am complaining about: #10413 (comment)

Hovering over the "Editor Language Status" displays:

"No Package.swift"
Apple Swift version 5.7.2....

Hi @H-G-Hristov . I think you're correct that you are seeing results from another extension. I'd guess that it's the Objective-C extension, but I'm not particularly knowledgeable about extensions other than the C/C++ Extension. You could try disabling one extension at a time, to identify which is generating those results.

[H-G-Hristov]

I set "C_Cpp.experimentalFeatures": "enabled", then I disabled the Swift extension https://marketplace.visualstudio.com/items?itemName=sswg.swift-lang
And the latter issue disappeared, which is a different the the former (original issue at the top). BTW even in Swift extension rendering the <std::string> string appears broken so maybe it is a string processing issue:

So basically I have two separate issues:

1. Doxygen strings are improperly rendered
2. The Swift extension takes over the C++ files resulting in various issues

Do I need to report additional issue? What would be the way forward? In my project I have C++ and Swift code I'd like to have both extensions enabled.

I believe the root cause of the doxygen hover bug with is due to #6020 , although it seems strange that it doesn't repro with std::vector<int>.

Repro code is like:

#include <vector>
#include <string>
/**
 * @return std::vector<std::string>
*/
std::vector<std::string> func()
{
    return std::vector<std::string>{};
}
