# For code formatting we have clang-format.
|
|
#
|
|
# But it's not sane to apply clang-format for whole code base,
|
|
# because it sometimes makes worse for properly formatted files.
|
|
#
|
|
# It's only reasonable to blindly apply clang-format only in cases
|
|
# when the code is likely to be out of style.
|
|
#
|
|
# For this purpose we have a script that will use very primitive heuristics
|
|
# (simple regexps) to check if the code is likely to have basic style violations.
|
|
# and then to run formatter only for the specified files.
