Doxide fails to parse bit-fields

[Corristo]

For example, this definition

struct Foo {
   unsigned char low : 4 {};
   unsigned char high : 4 {};
};

will cause doxide to print the warning

warning: parse error at ': 4', but will continue

for both bit-fields.

Thanks for the report @Corristo. It looks like using a brace-initializer with a bitfield, rather than just the bitfield alone, gives a parse error from from tree-sitter-cpp, so this seems to be an upstream issue.

Checking the tree-sitter parse on their playground, your example fails to parse:

struct Foo {
   unsigned char low : 4 {};
   unsigned char high : 4 {};
};

whereas removing the brace-initializers seems to work:

struct Foo {
   unsigned char low : 4;
   unsigned char high : 4;
};

Is the documentation appearing correctly for you despite the warning messages?

The documentation appears to be correct.
