From: Michael Welsh Duggan <mwd <at> md5i.com> To: 22486 <at> debbugs.gnu.org Subject: bug#22486: CC Mode 5.33 (C++/l); Bad indentation in a hideous C++ struct Date: Thu, 28 Jan 2016 15:37:07 -0500
In the following C++ snippet:
template <typename Arg, typename... Args>
struct ArgListMatcher<Arg, Args...> :
ArgListMatcher<MakeIndices<CountRef<Arg>::value>,
MakeIndices<sizeof...(Args) - CountRef<Arg>::value, CountRef<Arg>::value>,
Arg, Args...>
{
using Parent = ArgListMatcher<
MakeIndices<CountRef<Arg>::value>,
MakeIndices<sizeof...(Args) + 1 - CountRef<Arg>::value,
CountRef<Arg>::value>, Arg, Args...>;
using Parent::ArgListMatcher;
};
Starting with "template" as the first line, the lines' contexts are
listed as:
syntax: ((topmost-intro 1)), indent: 0
syntax: ((topmost-intro-cont 1)), indent: 0
syntax: ((inher-intro 1)), indent: 4
syntax: ((template-args-cont 1 99)), indent: 19
syntax: ((member-init-intro 154)), indent: 23
syntax: ((defun-open 1)), indent: 0
All of these seem reasonable save for member-init-intro, which I
expected to be template-args-cont.
