From: Michael Welsh Duggan <mwd <at> md5i.com> To: 62841 <at> debbugs.gnu.org Subject: bug#62841: CC Mode 5.35.2 (Group); Template indentation problems Date: Fri, 14 Apr 2023 14:18:16 -0400
[Message part 1 (text/plain, inline)]
Package: cc-mode Package: cc-mode Load the included file, bar.cpp:
[bar.cpp (text/x-c\+\+src, attachment)]
[Message part 3 (text/plain, inline)]
For example:
emacs -Q /tmp/bar.cpp
Type:
C-x h C-M-\
First, note that std::variant is not indented with respect to std::pair.
Next, delete and re-insert the final angle bracket on the line that
reads:
std::pair<ipfix::InfoElementID,std::vector<T>>,
Note the re-indention.
template <typename T>
using value_variant=3D
std::pair<
std::variant<
ipfix::octetArray_t,
ipfix::unsigned8_t,
ipfix::unsigned16_t,
ipfix::unsigned32_t,
ipfix::unsigned64_t,
ipfix::signed8_t,
ipfix::signed16_t,
ipfix::signed32_t,
ipfix::signed64_t,
ipfix::float32_t,
ipfix::float64_t,
ipfix::boolean_t,
ipfix::macAddress_t,
ipfix::string_t,
ipfix::dateTimeSeconds_t,
ipfix::dateTimeMilliseconds_t,
ipfix::dateTimeMicroseconds_t,
ipfix::dateTimeNanoseconds_t,
ipfix::ipv4Address_t,
ipfix::ipv6Address_t,
std::pair<ipfix::InfoElementID,std::vector<T>>,
std::pair<ipfix::TemplateID,std::vector<std::vector<T>>>,
std::pair<std::vector<
std::pair<
ipfix::TemplateID,
std::vector<std::vector<T>>>>>>,
ipfix::length_t>;
Then, try C-x h C-M-\ again. Note another reindentation.
template <typename T>
using value_variant=3D
std::pair<
std::variant<
ipfix::octetArray_t,
ipfix::unsigned8_t,

ipfix::signed32_t,
ipfix::signed64_t,
ipfix::float32_t,
ipfix::float64_t,
ipfix::boolean_t,
ipfix::macAddress_t,
ipfix::string_t,
ipfix::dateTimeSeconds_t,
ipfix::dateTimeMilliseconds_t,
ipfix::dateTimeMicroseconds_t,
ipfix::dateTimeNanoseconds_t,
ipfix::ipv4Address_t,
ipfix::ipv6Address_t,
std::pair<ipfix::InfoElementID,std::vector<T>>,
std::pair<ipfix::TemplateID,std::vector<std::vector<T>>>,
std::pair<std::vector<
std::pair<
ipfix::TemplateID,
std::vector<std::vector<T>>>>>>,
ipfix::length_t>;
Type C-x h C-M-\ again. Another re-indentation. This
one is stable, but incorrect.
