# Configuration of clang-format
# =============================
#
# Tested to work with versions: 8 to 11.

# This causes parameters on continuations to align to the opening brace.
#
#   like_this_long_name(parameter_one,
#                       parameter_two,
#                       parameter_three);
#
AlignAfterOpenBracket: 'Align'

# Disallow short functions on one line; break them up.
AllowShortBlocksOnASingleLine: false

# These two settings trigger stacking of parameters in most cases; this is
# easier to read and also makes diffs easier to read (since an added or removed
# parameter is obvious). For example, function calls will look like this:
#
#   like_this_long_name(parameter_one,
#                       parameter_two,
#                       parameter_three,
#                       parameter_four,
#                       parameter_five,
#                       parameter_six);
#
# Instead of:
#
#   like_this_long_name(parameter_one, parameter_two, parameter_three, parameter_four,
#                       parameter_five, parameter_six);

#
ConstructorInitializerIndentWidth: 4

# Make access modifier slightly more visible.

# This will unfortunately use spaces in some cases where it's not desired (like
# function calls) but the overall result is better since it will allow
# alignment to work properly with different tab width settings.
ContinuationIndentWidth: 4

# This tries to match Blender's style as much as possible. One
