Not working keyword highlighting in Clion with enabled Reshaper

[N1ceL]

• The color of the types like 'typedef unsigned int uint32' (uint32) is generally always ignored in keywords
• The color of the keywords like 'return' is ignored if ReSharper is enabled
• RegExp colors work where they don't need to

Unfortunately, this plugin does not work as it should, and there is no alternative to it. I hope it can be fixed (at least the keywords detection for typdefs and instruction with enabled ReSharper)

• Can you check if your color settings matches selected color theme? I see that settings are for "Dark 2", but you could use another theme (Editor->Color scheme ->General).
• As for RegExp - can you give an example of regexp and when it works wrongly?
• I also see that on settings open in Rider by default is selected a wrong theme (in my case Rider Dark instead of just Dark), I will take a look into that.

P.S. For me it works as expected in Rider for cpp file.

@clutcher

• Yes, it's correct, also I tried to change the color for both themes and choose a "Dark" back, but the problem still remained. This happens only with the typedef words (always), and if ReSharper is enabled it breaks all other keywords too (like return/if/etc instructions). Keyword highlighting work for me only in one case: if it is not typedef and if ReSharper is disabled it can work for basic keywords.

• Example with RegExp : It may be problematic to fix this (the only idea is to check the current color and compare it with the color of the comment/undefined if at all possible). But also if possible to fix the keywords fully (typedefs, and instructions with enabled ReSharper), then it will be perfect even without RegExp

@N1ceL so you are using CLion with that "resharper" checkbox not Rider?

@N1ceL

• I checked clion with resharper checkbox.
  • "return" keyword works as expected.
  • "uint32" doesn't work as it is not a keyword technically. Some time ago I put a "hack", so it could work as a keyword highlight (I think in #51 ), I'll check if I can do something similar for "resharper" checkbox.
• As for regexp - you didn't send the regexp itself, but if if is just "uint32", then it works as expected and highlights everything including comments. If you want to exclude comments, there should be something more complex like \/\*[\s\S]*?\*\/|(\buint32\b) . You can use chatgpt to generate regexepes for you and some online regexp tool for testing (for example https://regex101.com/ ).

So right now it looks like that I should check if uint32 can work as "keyword" for Clion+Resharper? Am I right or missed something from your request?

[N1ceL]

@clutcher Thanks for the help with RegExp. Yes, it looks like enabled "Clion -> Advanced Settings -> ReSharper" breaks something in keyword highlighting, however RegExp works with ReSharper. I think my problem is not important, keyword highlighting won't work with ReSharper, but RegExp is now normal

@N1ceL

• Great that RegExp helped you.
• What about keywords? "Return" and other keywords from the list https://en.cppreference.com/w/cpp/keyword should work. I checked and they are working with both enabled and disabled Resharper checkbox.
• With uint32 I won't be able to do anything, only regexp can help here.

@N1ceL Are you using Windows? In https://blog.jetbrains.com/clion/2023/11/clion-nova/#notable_differences is written that this is Windows only thing, that could explain, why on my Linux instance there are no issues.

[N1ceL]

@clutcher Everything works fine through RegExp, I'll just use it instead of Keywords. Yes, this happens on Windows with ReSharper only and only for Keywords, RegExp is fine,

[clutcher]

@N1ceL Regexp is much slower compared to keywords. I will keep this bug open and will find a way how to investigate what's going on with Windows+Resharper.

@N1ceL It was a long journey... So Jetbrains did major changes with that "Resharper" checkbox with fully disabled big part of functionality and bugs in fallback scenarious. There are a bunch of tickets relates to this issues:

• https://youtrack.jetbrains.com/issue/CPP-36085/Unable-to-port-code-to-CLion-Nova
• https://youtrack.jetbrains.com/issue/CPP-20180/Clangd-completion-for-Objective-C
• https://youtrack.jetbrains.com/issue/CPP-38437
• https://youtrack.jetbrains.com/issue/CPP-38486/CLion-2024.1-doesnt-seem-to-have-com.intellij.modules.cidr.lang-when-using-ReSharper-aka-CLion-Nova

It took for me some time to rewrite code and return most part of functionality back with CLion Nova engine. I would release it this week.

Should be fixed in 2024.1.26.
