Are there any tools counting lines of code AND what those lines are doing? (reddthat.com)

I've tried a few tools like cloc to count the lines of code within my cpp project.

However, they are pretty surface level and just count the lines.

Is there anything that is able to show how many lines are for classe, imports, simple aliases, typedefs, and more detailed info like that.

My codebase is using C++ 20 modules and a lot of it is just imports and namespace aliases, so just counting the lines is pretty inaccurate. A lot of the files are simply just 10-20 lines at the header for imports, etc, and then just a small child class with constructors.

Which is to say that it's >50% "filler" in a lot of files.

If anyone knows any tools for this, ideally FOSS, please let me know. Thanks!

I'm unsure if that's even possible in C++ for a "normal program" instead of requiring a full-fledged compiler and even maybe a linker, as C++ syntax is completely context-dependent. There's no way to tell if i+=b; increments a value or is actually a dynamic hierarchy cast that prints a message to screen and invokes a vector copy with data downloaded from the internet.

I'd venture there's something in Clang that does this? (clang-tidy, clang-format, who knows), since they implement the syntax tree parser thing.

I didn't even think about how context dependent C++ is until you mentioned that. That's a really good point

This is a lot more complicated than I first anticipated. I guess its probably not a common tool then 😅
