Expected Behavior

Documentation says support for Rider, C++ and angle brackets. I would expect template/generic declaration angle brackets to be rainbow-ified.

Current Behavior

They are not:

Code snippet for reproduce

Any nested angle bracket usage, e.g. `TArray<TArray<float>>`.

Hey there, @buchananwill! I'm here to help you with any bugs, questions, or contributions you have. Let's tackle this together!

The issue you're experiencing with angle brackets not being rainbow-ified in C++ on Rider might be related to a configuration setting. Ensure that the "Enable rainbow angle brackets" option is checked in the Rainbow Brackets plugin settings. This setting is necessary for angle brackets to be colorized ^[1].

Additionally, it's worth noting that there have been recent improvements related to C++ support in the Rainbow Brackets plugin, specifically for Rider. The changelog for version 2023.3.9 mentions fixes for Clang/CPP/Objective-C related files support in Rider ^[2]. Make sure your plugin is updated to the latest version to benefit from these improvements.

After investigation, it appears to be the same issue as another one reported in CLion. Currently, Rider has also adopted the new C++ engine, but unfortunately, the new engine does not fully support the PSI tree. For more details, please refer to: #2762 (comment)

we can only wait for JetBrains to make a fully-featured PSI tree, after that, Indent guidelines for Nova could be possible.

it is related to JetBrains's youtrack ticket and my ticket for support Nova 9 months ago.

Ok. It's not a deal breaker, but I don't think I can disable Resharper C++ because I think that's the implementation Rider uses to hook into Unreal Engine? It would be very handy for quite a lot of UE stuff though, where TObjectPtr often adds a second layer of `<>`.

Unfortunately, I was unable to find a way to disable the new C++ engine.
