Subject: bug#60397: 29.0.60; c++-ts-mode could report better defun names
Date: Thu, 29 Dec 2022 08:42:03 +0100

The defun names reported by c++-ts-mode could still need a couple of
improvements:

1) In a buffer with c++-ts-mode and which-function-mode enabled, and
this content:

struct S {
  int f1(int x) {
    return x + 1;
  }
  int g1(int x);
};

int S::g1(int x) {
  return x + 1;
}

Inside the inline f1 function definition, which-function-mode shows
"S.f1". But inside the out-of-line g1 function definition, it shows
"n/a" instead of "S.g1". (Not limited to structs. Classes have the same
problem.)

2) Namespaces are not handled. Given this content:

namespace n {
int f1(int x) {
  return x + 1;
}
}

namespace {
int f2(int x) {
  return x + 1;
}
}

Inside the f1 and f2 function bodies, which-function-mode shows "f1" and
"f2", respectively. It would be better if it showed "n.f1" for the
former, and perhaps something like "(anonymous).f2" for the latter.
