Bug ID: 375282
Summary: Method return type inside template is unknown
Product: kdevelop
Version: 5.1.0
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Language Support: CPP (Clang-based)
Assignee: kdevelop-bugs-n...@kde.org
Reporter: nicolas.alva...@gmail.com
Target Milestone: ---
struct Question {
int answer();
};
template<typename T>
struct Foo {
Question* question();
int fortyTwo() {
auto x = question();
return x->answer();
}
};
If I have a class template with a method ('fortyTwo') calling another
('question'), the tooltip on 'question' shows the correct type, but it seems
the type of the function call as an expression is unknown. Therefore, the type
of 'x' is unknown (tooltip says 'auto'), and 'answer' is not highlighted
(remains black). This only happens if Foo is a template, but happens even if
nothing in the class actually depends on T (as in the example).
"return question()->answer();" shows the same problem, but with "auto" it's
clearer that the problem is the type of the returned value.
An example of real-world code showing this problem is
KDevelop::AbstractContextBuilder<T>::topContext(). It returns
"currentContext()->topContext();", and the 'topContext' there is not
highlighted.
I'm using libclang 3.8.1.
