Enumerator

OAS_DontAlign

Do not align operands of binary and ternary expressions.

  int aaa = bbbbbbbbbbbbbbb
            + ccccccccccccccc;
\endcode

OAS_AlignAfterOperator

Horizontally align operands of binary and ternary expressions.

This is similar to ``OAS_Align``, except when
``BreakBeforeBinaryOperators`` is set, the operator is un-indented so
that the wrapped operand is aligned with the operand on the first line.
\code
  int aaa = bbbbbbbbbbbbbbb
          + ccccccccccccccc;

◆ SpaceBeforeParensStyle

enum clang::format::FormatStyle::SpaceBeforeParensStyle : int8_t

Different ways to put a space before opening parentheses.

Enumerator
SBPO_Never	This is deprecated and replaced by `Custom` below, with all `SpaceBeforeParensOptions` but `AfterPlacementOperator` set to `false`.
SBPO_ControlStatements	Put a space before opening parentheses only after control statement keywords (`for/if/while...`). void f() { if (true) { f(); } }
SBPO_ControlStatementsExceptControlMacros	Same as `SBPO_ControlStatements` except this option doesn't apply to ForEach and If macros. This is useful in projects where ForEach/If macros are treated as function calls instead of control statements. `SBPO_ControlStatementsExceptForEachMacros` remains an alias for backward compatibility. void f() { Q_FOREACH(...) { f(); } }
SBPO_NonEmptyParentheses	Put a space before opening parentheses only if the parentheses are not empty. void() { if (true) { f(); g (x, y, z); } }

◆ TrailingCommaStyle

enum clang::format::FormatStyle::TrailingCommaStyle : int8_t

The style of inserting trailing commas into container literals.

Enumerator

TCS_None

Do not insert trailing commas.

TCS_Wrapped

Insert trailing commas in container literals that were wrapped over multiple lines.

Note that this is conceptually incompatible with bin-packing, because the trailing comma is used as an indicator that a container should be formatted one-per-line (i.e. not bin-packed). So inserting a trailing comma counteracts bin-packing.

UT_Never	Never use tab.
UT_ForIndentation	Use tabs only for indentation.
UT_ForContinuationAndIndentation	Fill all leading whitespace with tabs, and use spaces for alignment that appears within a line (e.g. consecutive assignments and declarations).
UT_AlignWithSpaces	Use tabs for line continuation and indentation, and spaces for alignment.
UT_Always	Use tabs whenever we need to fill whitespace that spans at least from one tab stop to the next one.

◆ Cpp11BracedListStyle

bool clang::format::FormatStyle::Cpp11BracedListStyle

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.

true:                                  false:
vector<int> x{1, 2, 3, 4};     vs.     vector<int> x{ 1, 2, 3, 4 };

bool clang::format::FormatStyle::ExperimentalAutoDetectBinPacking

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. \endnote

Specify whether access modifiers should have their own indentation level.

When false, access modifiers are indented (or outdented) relative to the record members, respecting the AccessModifierOffset. Record members are indented one level below the record. When true, access modifiers get their own indentation level. As a consequence, record members are always indented 2 levels below the record, regardless of the access modifier presence. Value of the AccessModifierOffset is ignored.

◆ IndentCaseBlocks

bool clang::format::FormatStyle::IndentCaseBlocks

Indent case label blocks one level from the case label.

When false, the block following the case label uses the same indentation level as for the case label, treating the case label the same as an if-statement. When true, the block gets indented as a scope block.

false:                                 true:
switch (fool) {                vs.     switch (fool) {

◆ IndentCaseLabels

bool clang::format::FormatStyle::IndentCaseLabels

Indent case labels one level from the switch statement.

When false, use the same indentation level as for the switch statement. Switch statement body is always indented one level more than case labels (except the first block following the case label, which itself indents the code - unless IndentCaseBlocks is enabled).

false:                                 true:
switch (fool) {                vs.     switch (fool) {

◆ JavaImportGroups

std::vector<std::string> clang::format::FormatStyle::JavaImportGroups

A vector of prefixes ordered by the desired groups for Java imports.

One group's prefix can be a subset of another - the longest prefix is always matched. Within a group, the imports are ordered lexicographically. Static imports are grouped separately and follow the same group rules. By default, static imports are placed before non-static imports, but this behavior is changed by another option, SortJavaStaticImport.

In the .clang-format configuration file, this can be configured like in the following yaml example. This will result in imports being formatted as in the Java example below.

JavaImportGroups: [com.example, com, org]

import static com.example.function1;
 
import static com.test.function2;
 
import static org.example.function3;
 
import com.example.ClassA;
import com.example.Test;

◆ Macros

std::vector<std::string> clang::format::FormatStyle::Macros

A list of macros of the form <definition>=<expansion> .

Code will be parsed with macros expanded, in order to determine how to interpret and format the macro arguments.

For example, the code:

A(a*b);

will usually be interpreted as a call to a function A, and the multiplication expression will be formatted as a * b.

If we specify the macro definition:

Macros:

- A(x)=x

the code will now be parsed as a declaration of the variable b of type a*, and formatted as a* b (depending on pointer-binding rules).

Features and restrictions:

Both function-like macros and object-like macros are supported.
Macro arguments must be used exactly once in the expansion.
No recursive expansion; macros referencing other macros will be ignored.
Overloading by arity is supported: for example, given the macro definitions A=x, A()=y, A(a)=a

A; -> x;
A(); -> y;
A(z); -> z;
A(a, b); // will not be expanded.

If Always, always bin-packs Objective-C protocol conformance list items into as few lines as possible whenever they go over ColumnLimit.

If Never, lays out Objective-C protocol conformance list items onto individual lines whenever they go over ColumnLimit.

Always (or Auto, if BinPackParameters=true):

◆ QualifierAlignment

QualifierAlignmentStyle clang::format::FormatStyle::QualifierAlignment

Different ways to arrange specifiers and qualifiers (e.g.

const/volatile).

Warning: Setting QualifierAlignment to something other than Leave, COULD lead to incorrect code formatting due to incorrect decisions made due to clang-formats lack of complete semantic information. As such extra care should be taken to review code changes made by the use of this option. \endwarning

◆ QualifierOrder

std::vector<std::string> clang::format::FormatStyle::QualifierOrder

The order in which the qualifiers appear.

Order is an array that can contain any of the following:

const
inline
static
friend
constexpr
volatile
restrict
type

Note: It must contain type. \endnote

Items to the left of type will be placed to the left of the type and aligned in the order supplied. Items to the right of type will be placed to the right of the type and aligned in the order supplied.

QualifierOrder: [inline, static, type, const, volatile]

◆ RawStringFormats

std::vector<RawStringFormat> clang::format::FormatStyle::RawStringFormats

Defines hints for detecting supported languages code blocks in raw strings.

A raw string with a matching delimiter or a matching enclosing function name will be reformatted assuming the specified language based on the style for that language defined in the .clang-format file. If no style has been defined in the .clang-format file for the specific language, a predefined style given by BasedOnStyle is used. If BasedOnStyle is not found, the formatting is based on LLVM style. A matching delimiter takes precedence over a matching enclosing function name for determining the language of the raw string contents.

If a canonical delimiter is specified, occurrences of other delimiters for the same language will be updated to the canonical if possible.

There should be at most one specification per language and each delimiter and enclosing function should not occur in multiple specifications.

To configure this in the .clang-format file, use:

RawStringFormats:
  - Language: TextProto
      Delimiters:
        - pb
        - proto
      EnclosingFunctions:
        - PARSE_TEXT_PROTO
      BasedOnStyle: google
  - Language: Cpp
      Delimiters:
        - cc
        - cpp
      BasedOnStyle: LLVM
      CanonicalDelimiter: cc

◆ SpacesInLineCommentPrefix

SpacesInLineComment clang::format::FormatStyle::SpacesInLineCommentPrefix

How many spaces are allowed at the start of a line comment.

To disable the maximum set it to -1, apart from that the maximum takes precedence over the minimum.

Minimum = 1
Maximum = -1
// One space is forced
 
//  but more spaces are possible
 
Minimum = 0
Maximum = 0
//Forces to start every comment directly after the slashes

Note that in line comment sections the relative indent of the subsequent lines is kept, that means the following:

before:                                   after:
Minimum: 1
//if (b) {                                // if (b) {
//  return true;                          //   return true;
//}                                       // }

///    - Bar                              ///   - Bar

This option has only effect if ReflowComments is set to true.

◆ SpacesInParens

SpacesInParensStyle clang::format::FormatStyle::SpacesInParens

If true, spaces will be inserted after ( and before ).

This option is deprecated. The previous behavior is preserved by using SpacesInParens with Custom and by setting all SpacesInParensOptions to true except for InCStyleCasts and InEmptyParentheses.

Version: 3.7 Defines in which cases spaces will be inserted after ( and before ).; 17

◆ SpacesInParensOptions

SpacesInParensCustom clang::format::FormatStyle::SpacesInParensOptions

Control of individual spaces in parentheses.

If SpacesInParens is set to Custom, use this to specify how each individual space in parentheses case should be handled. Otherwise, this is ignored.

# Example of usage:
SpacesInParens: Custom
SpacesInParensOptions:
  ExceptDoubleParentheses: false
  InConditionalStatements: true
  InEmptyParentheses: true

◆ SpacesInSquareBrackets

bool clang::format::FormatStyle::SpacesInSquareBrackets

If true, spaces will be inserted after [ and before ].

Lambdas without arguments or unspecified size array declarations will not be affected.

true:                                  false:
int a[ 5 ];                    vs.     int a[5];

◆ StatementAttributeLikeMacros

std::vector<std::string> clang::format::FormatStyle::StatementAttributeLikeMacros

Macros which are ignored in front of a statement, as if they were an attribute.

So that they are not parsed as identifier, for example for Qts emit.

AlignConsecutiveDeclarations: true
StatementAttributeLikeMacros: []
unsigned char data = 'x';
emit          signal(data); // This is parsed as variable declaration.
 
AlignConsecutiveDeclarations: true
StatementAttributeLikeMacros: [emit]
unsigned char data = 'x';
emit signal(data); // Now it's fine again.

◆ StatementMacros

std::vector<std::string> clang::format::FormatStyle::StatementMacros

A vector of macros that should be interpreted as complete statements.

Typical macros are expressions, and require a semi-colon to be added; sometimes this is not the case, and this allows to make clang-format aware of such cases.

For example: Q_UNUSED

◆ TableGenBreakingDAGArgOperators

std::vector<std::string> clang::format::FormatStyle::TableGenBreakingDAGArgOperators

Works only when TableGenBreakInsideDAGArg is not DontBreak.

The string list needs to consist of identifiers in TableGen. If any identifier is specified, this limits the line breaks by TableGenBreakInsideDAGArg option only on DAGArg values beginning with the specified identifiers.

For example the configuration,

TableGenBreakInsideDAGArg: BreakAll

TableGenBreakingDAGArgOperators: [ins, outs]

makes the line break only occurs inside DAGArgs beginning with the specified identifiers ins and outs.

let DAGArgIns = (ins
    i32:$src1,
    i32:$src2
);
let DAGArgOtherID = (other i32:$other1, i32:$other2);
let DAGArgBang = (!cast<SomeType>("Some") i32:$src1, i32:$src2)

◆ TypenameMacros

std::vector<std::string> clang::format::FormatStyle::TypenameMacros

A vector of macros that should be interpreted as type declarations instead of as function calls.

These are expected to be macros of the form:

STACK_OF(...)

In the .clang-format configuration file, this can be configured like:

TypenameMacros: [STACK_OF, LIST]

For example: OpenSSL STACK_OF, BSD LIST_ENTRY.

◆ TypeNames

std::vector<std::string> clang::format::FormatStyle::TypeNames

A vector of non-keyword identifiers that should be interpreted as type names.

A *, &, or && between a type name and another non-keyword identifier is annotated as a pointer or reference token instead of a binary operator.
