I mean, the only time a variable is solely a declaration is extern, so check the storage class

I think that's clang_Cursor_getStorageClass(cursor) or something like that

There's also clang_isCursorDefinition I think, which may be what you want

I swear I tried this before but I tried it again and it worked so idk

either way thanks!

[waxen zodiac]

Pro tip: move to the C++ libclang api

You might run into missing features in C one and then have to migrate 😛

yeah I was gonna use that for the real project but this is just a proof of concept which is just a frankenstine of the example on the llvm website xd

ik its been a while but Im getting back into this project and I cant find any reference of the C++ API
could you provide a link to the docs?

I dunno I just looked at the headers

And on the tiny examples you get when googling "clang libtooling"

And when it's a static data member declared without an initializer.

struct A { static int x; };

here's a reference that should help with this. the VS2022 "Struct Layout" extension uses this internally as a fallback when it can't pull this info from pdb files, or just generally when whatever else VS provides for utils through their SDK's involving this stuff isn't good enough to extract the context needed to collect accurate info from the source shown in the IDE: https://github.com/Viladoman/StructLayout/blob/main/Parsers/ClangLayout/src/Parser.cpp
