BreakConstructorInitializersBeforeComma: false

# BreakStringLiterals (bool)
# Allow breaking string literals when formatting.
#BreakStringLiterals:

# ColumnLimit (unsigned)

# If true, format braced lists as best suited for C++11 braced lists.
# Important differences: - No spaces inside the braced list. - No line break before the closing brace. - Indentation with the continuation indent, not with the block indent.
# Fundamentally, C++11 braced lists are formatted exactly like function calls would be formatted in their place. If the braced list follows a name (e.g. a type or variable name), clang-format formats as if the {} were the parentheses of a function call with that name. If there is no name, a zero-length name is assumed.
Cpp11BracedListStyle: false

# DerivePointerAlignment (bool)
# If true, analyze the formatted file for the most common alignment of & and \*. PointerAlignment is then used only as fallback.

#DisableFormat:

# ExperimentalAutoDetectBinPacking (bool)
# If true, clang-format detects whether function calls and definitions are formatted with one parameter per line.
# Each call can be bin-packed, one-per-line or inconclusive. If it is inconclusive, e.g. completely on one line, but a decision needs to be made, clang-format analyzes whether there are other bin-packed cases in the input file and act accordingly.
# NOTE: This is an experimental flag, that might go away or be renamed. Do not use this in config files, etc. Use at your own risk.
#ExperimentalAutoDetectBinPacking:

# ForEachMacros (std::vector<std::string>)
# A vector of macros that should be interpreted as foreach loops instead of as function calls.
# These are expected to be macros of the form:
# FOREACH(<variable-declaration>, ...)
#  <loop-body>
# In the .clang-format configuration file, this can be configured like:
# ForEachMacros: ['RANGES_FOR', 'FOREACH']
# For example: BOOST_FOREACH.
#ForEachMacros:

# IncludeCategories (std::vector<IncludeCategory>)
# Regular expressions denoting the different #include categories used for ordering #includes.
# These regular expressions are matched against the filename of an include (including the <> or “”) in order. The value belonging to the first matching regular expression is assigned and #includes are sorted first according to increasing category number and then alphabetically within each category.
# If none of the regular expressions match, INT_MAX is assigned as category. The main header for a source file automatically gets category 0. so that it is generally kept at the beginning of the #includes (http://llvm.org/docs/CodingStandards.html#include-style). However, you can also assign negative priorities if you have certain headers that always need to be first.
# To configure this in the .clang-format file, use:
# IncludeCategories:
#   - Regex:           '^"(llvm|llvm-c|clang|clang-c)/'
#     Priority:        2
#   - Regex:           '^(<|"(gtest|isl|json)/)'
