modernize-use-default-member-init¶
This check converts a default constructor’s member initializers into the new default member initializers in C++11. Other member initializers that match the default member initializer are removed. This can reduce repeated code or allow use of ‘= default’.
struct A {
A() : i(5), j(10.0) {}
A(int i) : i(i), j(10.0) {}
int i;
double j;
};
// becomes
struct A {
A() {}
A(int i) : i(i) {}
int i{5};
double j{10.0};
};
Note
Only converts member initializers for built-in types, enums, and pointers. The readability-redundant-member-init check will remove redundant member initializers for classes.
Options¶
- UseAssignment
If this option is set to non-zero (default is 0), the check will initialise members with an assignment. For example:
struct A {
A() {}
A(int i) : i(i) {}
int i = 5;
double j = 10.0;
};
- IgnoreMacros
If this option is set to non-zero (default is 1), the check will not warn about members declared inside macros.
