Bug ID: 43988
Summary: formatting broken when using inline if inside of
templates in class initializer list
Product: clang
Version: 9.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Formatter
Assignee: unassignedclangb...@nondot.org

clang-format gets confused when dealing with inline ifs in templates within
class initializer lists.
The behavior got worse with clang-format-9, as the indentation of the following
entries in the initializer list are wrongly indented.
==============using braces and clang-format-9==============
template <int someInt> class Base { Base(int i){}; };
template <bool someBool> class Derived : public Base<someBool ? 2 : 3> {
public:
Derived()
: Base<(someBool ? 2 : 3)>{35}, _someMember{3}, _someMember2{2}, //
<-- desired indentation
_someMember3{2} {}
private:
int _someMember;
int _someMember2;
int _someMember3;
};
==============without braces and clang-format-9==============
template <int someInt> class Base { Base(int i){}; };
template <bool someBool> class Derived : public Base<someBool ? 2 : 3> {
public:
Derived()
: Base < someBool
? 2
: 3 > {35},
_someMember{3}, _someMember2{2}, _someMember3{2} {}
// <-- wrong indentation
private:
int _someMember;
int _someMember2;
int _someMember3;
};
==============without braces and clang-format-8==============
template <int someInt> class Base { Base(int i){}; };
template <bool someBool> class Derived : public Base<someBool ? 2 : 3> {
public:
Derived()
: Base < someBool
? 2
: 3 > {35},
_someMember{3}, _someMember2{2}, _someMember3{2} {}
// <-- slightly better indentation, but still wrong.
private:
int _someMember;
int _someMember2;
int _someMember3;
};
============================================================
