From: Michael Welsh Duggan <mwd <at> md5i.com> To: 56130 <at> debbugs.gnu.org Subject: bug#56130: CC Mode 5.35.1 (C++//l); Indentation using braced initializer lists Date: Tue, 21 Jun 2022 16:46:55 -0400
[Message part 1 (text/plain, inline)]
Package: cc-mode This could possibly be considered a feature request. It is relevant since C++ 11. Consider the following code:
[Message part 2 (text/x-c\+\+, inline)]
#include <utility>
template <typename T>
struct Foo {
Foo()
: a(1,
2) // This indents well
{}
std::pair<int, int> a;
Foo(int)
: a{2,
3} // This indents poorly
{}
};
[Message part 3 (text/plain, inline)]
Braced initializer lists don't line up well, as opposed to parenthesis.
