### CLANG-FORMAT-WRANGLING

# Version 7 and earlier doesn't understand all the options we would like.
|
|
# Version 12 handled lambdas nicely and was the norm for Calamares 3.2.
|
|
# Version 13 was also ok.
|
|
# Version 14 behaves differently with short-functions-in-class,
|
|
# spreading functions out that 13 keeps on one line. To avoid
|
|
# ping-pong commits, forbid 14.
|
|
# Version 15 is available on recent-ish Ubuntus and FreeBSD, pick it.
|
|
# It also supports inserting braces, which is the one thing we kept
|
|
# astyle around for.
|
|
# Version 16 is available on openSUSE and is ok as well.
|
|
# Version 17 is available on FreeBSD and KaOS and is ok as well.
