# CGAL clang-format configuration
# This file defines the code formatting style for C++ files in the CGAL project.

Language:        Cpp
BasedOnStyle:  LLVM

# Indentation
AccessModifierOffset: -2  # Indent public:/private:/protected: 2 spaces to the left

# Function formatting
AllowShortFunctionsOnASingleLine: Inline  # Allow short inline/member functions on one line, but not free functions
AlwaysBreakAfterReturnType: None  # Don't force return type on separate line

# Parameter and argument formatting
BinPackParameters: false  # Put each parameter on its own line for better readability

# Constructor formatting
BreakConstructorInitializers: BeforeComma  # Put comma before each initializer: `MyClass() \n  , member1(val1) \n  , member2(val2)`

# Brace wrapping configuration
BreakBeforeBraces: Custom
BraceWrapping:
  AfterCaseLabel:  false       # Don't put brace on new line after case labels
  AfterClass:      true        # Put opening brace on new line after class definition
  AfterControlStatement: MultiLine  # Only break before braces if the control statement spans multiple lines
  AfterEnum:       false       # Don't break after enum
  AfterFunction:   false       # Don't break after function declaration (keep on same line)
  AfterNamespace:  false       # Don't break after namespace
  AfterObjCDeclaration: false  # Objective-C related (not used in CGAL)
  AfterStruct:     true        # Put opening brace on new line after struct definition
  AfterUnion:      false       # Don't break after union
  AfterExternBlock: false      # Don't break after extern "C" blocks
  BeforeCatch:     false       # Don't put catch on new line
  BeforeElse:      false       # Don't put else on new line
  BeforeLambdaBody: false      # Don't break before lambda body
  BeforeWhile:     false       # Don't put while on new line (do-while loops)
  IndentBraces:    false       # Don't indent the braces themselves
  SplitEmptyFunction: false    # Don't split empty functions across lines
  SplitEmptyRecord: false      # Don't split empty classes/structs across lines
  SplitEmptyNamespace: false   # Don't split empty namespaces across lines

# Line length
ColumnLimit:     120  # Maximum line length of 120 characters

# Pointer and reference alignment
# Force pointers and references to align with the type (e.g., `int* ptr` not `int *ptr`)
DerivePointerAlignment: false
PointerAlignment: Left

# Spacing in control statements
SpacesInConditionalStatement: false  # No extra spaces inside conditionals: `if(condition)` not `if( condition )`
SpaceBeforeParens: false  # No space before parentheses: `if(` not `if (`

# Include directive handling
SortIncludes:    Never  # Preserve the original order of #include statements (don't sort them)

# Preprocessor directive formatting
IndentPPDirectives: None  # Don't indent preprocessor directives (#ifdef, #include, etc.)

# Blank line handling
MaxEmptyLinesToKeep: 2  # Keep up to 2 consecutive blank lines
