why IntelliSense triggered on hover displayed html code

[Yujun Li (NewbieToEverything)]

Hi,

I am a newbie to C++, thank you for maintaining such a helpful extension!

I have installed the extension and compiler by following the instruction Using GCC with MinGW. However, a tooltip with raw HTML code appeared when I hovered over the 'vector' in the "helloworld.cpp". I have no clue why this happened.

I am not sure whether the problem lies in my VScode setting or the C++ extension one, because the other extension I used seems to suffer a similar issue. For the C++ extension, I switched the "C_Cpp.loggingLevel" to "Debug" to create log file, listing below is the resulting output.

Thank you in advance for any suggestions!

This is by design. The extension does not parse and convert HTML tags from comments into markups for VS Code to display as formatted text on the tooltip hover.

[Yujun Li (NewbieToEverything)]

No, our extension doesn't have any special handling to render HTML in doc comments.

This rendering failure is still biting me. Reinstalling VS code did not work for me. I also tried installing VScode on another laptop, no similar issue was observed. I guess this problem may root in my VScode, but I have no clue how to locate it.

Sean McManus (@sean-mcmanus) Michelle Matias (@michelleangela) Thank you for your time and for answering my question. Since this is nothing to do with the C++ extension, I think I'd better post this question to the VScode GitHub project instead.

[Sean McManus (sean-mcmanus)]

I believe this does have to do with the C/C++ extension and not VS Code. We simply do implement special handling for markup text in comments.

Sean McManus (@sean-mcmanus) is correct. In order to remove the HTML tags, the C/C++ extension would need to parse out the HTML from the comments and replace each HTML tag with a markup tag so that the comment will be formatted correctly when displayed on the tooltip. This is because, the C/C++ extension reads and parses the comments on a source file and sends them to the VS Code client to display on the tooltip. Currently the C/C++ extension does not parse out HTML tags, which results in HTML tags being displayed on the tooltip because the extension just sends them as raw strings to VS Code client.

A feature request for the C/C++ extension can be posted to add a feature to parse out HTML tags from code comments. It may get implemented depending on the received upvotes or its priority against other features.

Now I understand. I will start a feature request and see how it goes. Thx!
