From: Arsen Arsenović <arsen <at> aarsen.me> To: 66911 <at> debbugs.gnu.org Subject: bug#66911: CC Mode 5.35.2 (C++//l); Noise macro being taken as anchor to class-open Date: Fri, 03 Nov 2023 10:51:32 +0100
Package: cc-mode
<#secure method=pgpmime mode=sign>
Package: cc-mode
In the example below:
namespace a {
_BEGIN
template<>
struct foo
{ /* HERE */
};
}
// Local Variables:
// c-noise-macro-names: ("_BEGIN")
// End:
Pressing C-c C-s on the stat of the line marked HERE shows ((class-open
15)), which is the '_' of the '_BEGIN'. This appears to be wrong, as
the anchor should be the 'class' keyword on the line above, I believe.
Anchoring '{' on the class/struct/union that precedes it would also
enable implementing the GNU libstdc++ code style (as, AFAICT, it is
currently impossible to indent a class with a basic-offset added to the
column the 'template' keyword sits on).
