<pre>libclang seems to have added support for completion of incomplete types, but a
trivial type alias cause it to break:
template <typename T> struct A { void foo(); };
template <typename T> using B = A<T>;
template <typename T> struct C {
A<T> a;
B<T> b;
C() {
// a. completes
// b. doesn't complete
}
};
Completion for a. gives:
❯❯❯ c-index-test -code-completion-at=sample.cpp:9:11 sample.cpp
StructDecl:{TypedText A}{Text ::} (75)
CXXMethod:{ResultType void}{TypedText foo}{LeftParen (}{RightParen )} (34)
NotImplemented:{TypedText template} (40)
Completion contexts:
Dot member access
Completion for b. gives:
❯❯❯ c-index-test -code-completion-at=sample.cpp:9:11 sample.cpp
Completion contexts:
Dot member access</pre>
