# clang-format suggestions. Hopefully we can eventually improve clang-format to
|
||
# be configurable enough for our coding style. That’s why this CI check is OK
|
||
# to fail: the idea is that people can look through the output and ignore it if
|
||
# it’s wrong. (That situation can also happen if someone touches pre-existing
|
||
# badly formatted code and it doesn’t make sense to tidy up the wider coding
|
||
# style with the changes they’re making.)
