Helix recognizes C header files as C++ files

[DiddleDiddler]

I changed tab-width for C files in the languages.toml file and for .c files it works but the default indenting was used for every .h file.
In the statusline file-type shows cpp instead of c for header files.
I fixed by also setting the tab-width for cpp but because it sees them as C++ files I might get some C++ completion instead of C completion.

I don't know if this is an issue, is there a way to fix this?

the issue is, that very frequently C++ projects also use .h files for their C++ headers, which makes it extremely hard to figure out by just looking at the file names and not at the code (examples: kwin and qt come to mind immediately, as well as a lot of C++ projects from google like Carbon).

while an option to just try to look for neighboring .c/.cpp files with the same name as the .h file would work for those projects, it would still not work for a lot of C++, that prefer putting the .h files in a seperate folder (like googletest and simdjson)

the idea with just using C++ is, that C++ is supposed to be an almost superset of C (even if that is not actually super true in a lot of cases) and C++ highlighting should work correctly for all C files, but not vice-versa. the issue you have with the configuration in languages.toml is the drawback, but we are quite lucky, that the most common C++ language server (clangd) is also just a normal C language server, so that should (in most "normal" cases) not actually be a larger issue.

Yeah, I know most C++ header files are also using .h. Kinda bad that .hpp isn't really standardized or widely used.
But It doesn't really matter and I don't experience any issues so I'll close this.
