Subject: [PATCH 1/3] [clang-format][CMake] Generate formatting options docs
during build
This patch changes up the CMake configuration so that
ClangFormatStyleOptions.rst has the format style options section
generated by the dump_format_style.py python script during the build
rather than manually. This allows us to remove ~6000 lines of
automatically generated documentation from the repository.
If the context of the options is needed while generating the docs, it is
easy enough to open up the generated file with the options from within
the build directory after the clang-format-style-options target has been
built.

.. START_FORMAT_STYLE_OPTIONS
-.. _AccessModifierOffset:
-
-**AccessModifierOffset** (``Integer``) :versionbadge:`clang-format 3.3` :ref:`¶ <AccessModifierOffset>`
- The extra indent or outdent of access modifiers, e.g. ``public:``.
-
-.. _AlignAfterOpenBracket:
-
-**AlignAfterOpenBracket** (``BracketAlignmentStyle``) :versionbadge:`clang-format 3.8` :ref:`¶ <AlignAfterOpenBracket>`
- If ``true``, horizontally aligns arguments after an open bracket.
-
- This applies to round brackets (parentheses), angle brackets and square
- brackets.
-
- Possible values:
-
- * ``BAS_Align`` (in configuration: ``Align``)
- Align parameters on the open bracket, e.g.:
-
- .. code-block:: c++
-
- someLongFunction(argument1,
- argument2);
-
- * ``BAS_DontAlign`` (in configuration: ``DontAlign``)
- Don't align, instead use ``ContinuationIndentWidth``, e.g.:
-
- .. code-block:: c++
-
- someLongFunction(argument1,
- argument2);
-
- * ``BAS_AlwaysBreak`` (in configuration: ``AlwaysBreak``)
- Always break after an open bracket, if the parameters don't fit
- on a single line, e.g.:
-
- .. code-block:: c++
-
- someLongFunction(
- argument1, argument2);
-
- * ``BAS_BlockIndent`` (in configuration: ``BlockIndent``)
- Always break after an open bracket, if the parameters don't fit
- on a single line. Closing brackets will be placed on a new line.
- E.g.:
-
- .. code-block:: c++
-
- someLongFunction(
- argument1, argument2
- )
-
-
- .. note::
-
- This currently only applies to braced initializer lists (when
- ``Cpp11BracedListStyle`` is ``true``) and parentheses.

-
-.. _AlignArrayOfStructures:
-
-**AlignArrayOfStructures** (``ArrayInitializerAlignmentStyle``) :versionbadge:`clang-format 13` :ref:`¶ <AlignArrayOfStructures>`
- If not ``None``, when using initialization for an array of structs
- aligns the fields into columns.
-
-
- .. note::
-
- As of clang-format 15 this option only applied to arrays with equal
- number of columns per row.
-
- Possible values:
-
- * ``AIAS_Left`` (in configuration: ``Left``)
- Align array column and left justify the columns e.g.:
-
- .. code-block:: c++
-
- struct test demo[] =
- {
- {56, 23, "hello"},
- {-1, 93463, "world"},
- {7, 5, "!!" }
- };
-
- * ``AIAS_Right`` (in configuration: ``Right``)
- Align array column and right justify the columns e.g.:
-
- .. code-block:: c++
-
- struct test demo[] =
- {
- {56, 23, "hello"},
- {-1, 93463, "world"},
- { 7, 5, "!!"}
- };
-
- * ``AIAS_None`` (in configuration: ``None``)
- Don't align array initializer columns.

- Possible values:
-
- * ``OAS_DontAlign`` (in configuration: ``DontAlign``)
- Do not align operands of binary and ternary expressions.
- The wrapped lines are indented ``ContinuationIndentWidth`` spaces from
- the start of the line.
-
- * ``OAS_Align`` (in configuration: ``Align``)
- Horizontally align operands of binary and ternary expressions.
-
- Specifically, this aligns operands of a single expression that needs
- to be split over multiple lines, e.g.:
-
- .. code-block:: c++
-
- int aaa = bbbbbbbbbbbbbbb +
- ccccccccccccccc;
-
- When ``BreakBeforeBinaryOperators`` is set, the wrapped operator is
- aligned with the operand on the first line.
-
- .. code-block:: c++
-
- int aaa = bbbbbbbbbbbbbbb
- + ccccccccccccccc;
-
- * ``OAS_AlignAfterOperator`` (in configuration: ``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-block:: c++

- a semicolon.
-
-
- .. note::
-
- As of clang-format 16 this option is not a bool but can be set
- to the options. Conventional bool options still can be parsed as before.

- int a; // comment
- int ab; // comment
-
- int abc; // comment
- int abcd; // comment
-
- * ``TCAS_Always`` (in configuration: ``Always``)
- Align trailing comments.
-
- .. code-block:: c++
-
- int a; // comment
- int ab; // comment
-
- int abc; // comment
- int abcd; // comment
-
- * ``TCAS_Never`` (in configuration: ``Never``)
- Don't align trailing comments but other formatter applies.
-
- .. code-block:: c++
-
- int a; // comment
- int ab; // comment
-
- int abc; // comment
- int abcd; // comment
-
-
- * ``unsigned OverEmptyLines`` How many empty lines to apply alignment.
- When both ``MaxEmptyLinesToKeep`` and ``OverEmptyLines`` are set to 2,
- it formats like below.
-
- .. code-block:: c++
-
- int a; // all these
-
- int ab; // comments are
-
-
- int abcdef; // aligned
-
- When ``MaxEmptyLinesToKeep`` is set to 2 and ``OverEmptyLines`` is set
- to 1, it formats like below.
-
- .. code-block:: c++
-
- int a; // these are
-
- int ab; // aligned

- 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.
-
- .. code-block:: c++
-
- true: false:

-
-
-.. _ExperimentalAutoDetectBinPacking:
-
-**ExperimentalAutoDetectBinPacking** (``Boolean``) :versionbadge:`clang-format 3.7` :ref:`¶ <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.

- <loop-body>
-
- In the .clang-format configuration file, this can be configured like:
-
- .. code-block:: yaml
-
- ForEachMacros: [RANGES_FOR, FOREACH]
-
- For example: BOOST_FOREACH.
-
-.. _IfMacros:
-
-**IfMacros** (``List of Strings``) :versionbadge:`clang-format 13` :ref:`¶ <IfMacros>`
- A vector of macros that should be interpreted as conditionals
- instead of as function calls.
-
- These are expected to be macros of the form:
-
- .. code-block:: c++
-
- IF(...)
- <conditional-body>
- else IF(...)
- <conditional-body>
-
- In the .clang-format configuration file, this can be configured like:
-
- .. code-block:: yaml

-.. _IncludeBlocks:
-
-**IncludeBlocks** (``IncludeBlocksStyle``) :versionbadge:`clang-format 6` :ref:`¶ <IncludeBlocks>`
- Dependent on the value, multiple ``#include`` blocks can be sorted
- as one and divided based on category.
-
- Possible values:
-
- * ``IBS_Preserve`` (in configuration: ``Preserve``)
- Sort each ``#include`` block separately.
-
- .. code-block:: c++
-
- #include "b.h" into #include "b.h"

- #include "a.h" #include <lib/main.h>
-
- * ``IBS_Merge`` (in configuration: ``Merge``)
- Merge multiple ``#include`` blocks together and sort as one.
-
- .. code-block:: c++
-
- #include "b.h" into #include "a.h"
- #include "b.h"
- #include <lib/main.h> #include <lib/main.h>
- #include "a.h"
-
- * ``IBS_Regroup`` (in configuration: ``Regroup``)
- Merge multiple ``#include`` blocks together and sort as one.

-
- .. code-block:: c++
-
- #include "b.h" into #include "a.h"
- #include "b.h"
- #include <lib/main.h>
- #include "a.h" #include <lib/main.h>

-
-**IncludeCategories** (``List of IncludeCategories``) :versionbadge:`clang-format 3.8` :ref:`¶ <IncludeCategories>`

- used for ordering ``#includes``.
-
- `POSIX extended
- <https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html>`_
- regular expressions are supported.
-
- 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``
- (https://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.
-
- There is a third and optional field ``SortPriority`` which can used while
- ``IncludeBlocks = IBS_Regroup`` to define the priority in which
- ``#includes`` should be ordered. The value of ``Priority`` defines the
- order of ``#include blocks`` and also allows the grouping of ``#includes``
- of different priority. ``SortPriority`` is set to the value of
- ``Priority`` as default if it is not assigned.
-
- Each regular expression can be marked as case sensitive with the field
- ``CaseSensitive``, per default it is not.
-
- To configure this in the .clang-format file, use:
-
- .. code-block:: yaml
-
- IncludeCategories:
- - Regex: '^"(llvm|llvm-c|clang|clang-c)/'
- Priority: 2
- SortPriority: 2

-.. _IncludeIsMainRegex:
-
-**IncludeIsMainRegex** (``String``) :versionbadge:`clang-format 3.9` :ref:`¶ <IncludeIsMainRegex>`
- Specify a regular expression of suffixes that are allowed in the
- file-to-main-include mapping.
-
- When guessing whether a #include is the "main" include (to assign
- category 0, see above), use this regex of allowed suffixes to the header
- stem. A partial match is done, so that:
- - "" means "arbitrary suffix"
- - "$" means "no suffix"
-
- For example, if configured to "(_test)?$", then a header a.h would be seen
- as the "main" include in both a.cc and a_test.cc.
-
-.. _IncludeIsMainSourceRegex:
-
-**IncludeIsMainSourceRegex** (``String``) :versionbadge:`clang-format 10` :ref:`¶ <IncludeIsMainSourceRegex>`
- Specify a regular expression for files being formatted
- that are allowed to be considered "main" in the
- file-to-main-include mapping.
-
- By default, clang-format considers files as "main" only when they end
- with: ``.c``, ``.cc``, ``.cpp``, ``.c++``, ``.cxx``, ``.m`` or ``.mm``
- extensions.
- For these files a guessing of "main" include takes place
- (to assign category 0, see above). This config option allows for
- additional suffixes and extensions for files to be considered as "main".
-
- For example, if this option is configured to ``(Impl\.hpp)$``,
- then a file ``ClassImpl.hpp`` is considered "main" (in addition to
- ``Class.c``, ``Class.cc``, ``Class.cpp`` and so on) and "main
- include file" logic will be executed (with *IncludeIsMainRegex* setting
- also being respected in later phase). Without this option set,
- ``ClassImpl.hpp`` would not have the main include file put on top
- before any other include.
-
-.. _IndentAccessModifiers:
-
-**IndentAccessModifiers** (``Boolean``) :versionbadge:`clang-format 13` :ref:`¶ <IndentAccessModifiers>`
- 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.
-
- .. code-block:: c++
-
- false: true:
- class C { vs. class C {
- class D { class D {
- void bar(); void bar();
- protected: protected:
- D(); D();
- }; };
- public: public:
- C(); C();
- }; };
- void foo() { void foo() {
- return 1; return 1;
- } }
-
-.. _IndentCaseBlocks:
-
-**IndentCaseBlocks** (``Boolean``) :versionbadge:`clang-format 11` :ref:`¶ <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.
-
- .. code-block:: c++
-
- false: true:
- switch (fool) { vs. switch (fool) {
- case 1: { case 1:
- bar(); {
- } break; bar();
- default: { }
- plop(); break;
- } default:
- } {
- plop();
- }
- }
-
-.. _IndentCaseLabels:
-
-**IndentCaseLabels** (``Boolean``) :versionbadge:`clang-format 3.3` :ref:`¶ <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).
-
- .. code-block:: c++
-
- false: true:
- switch (fool) { vs. switch (fool) {
- case 1: case 1:
- bar(); bar();
- break; break;
- default: default:
- plop(); plop();
- } }
-
-.. _IndentExternBlock:
-
-**IndentExternBlock** (``IndentExternBlockStyle``) :versionbadge:`clang-format 11` :ref:`¶ <IndentExternBlock>`
- IndentExternBlockStyle is the type of indenting of extern blocks.
-
- Possible values:
-

-
-.. _IndentRequiresClause:
-
-**IndentRequiresClause** (``Boolean``) :versionbadge:`clang-format 15` :ref:`¶ <IndentRequiresClause>`
- Indent the requires clause in a template. This only applies when
- ``RequiresClausePosition`` is ``OwnLine``, ``OwnLineWithBrace``,

-
- true:
- template <typename It>
- requires Iterator<It>
- void sort(It begin, It end) {
- //....
- }
-
- false:

-**IndentWrappedFunctionNames** (``Boolean``) :versionbadge:`clang-format 3.7` :ref:`¶ <IndentWrappedFunctionNames>`
- Indent if a function definition or declaration is wrapped after the
- type.
-
- .. code-block:: c++

-
-.. _InsertBraces:
-
-**InsertBraces** (``Boolean``) :versionbadge:`clang-format 15` :ref:`¶ <InsertBraces>`
- Insert braces after control statements (``if``, ``else``, ``for``, ``do``,
- and ``while``) in C++ unless the control statements are inside macro
- definitions or the braces would enclose preprocessor directives.
-
- .. warning::
-
- Setting this option to ``true`` could lead to incorrect code formatting
- due to clang-format's lack of complete semantic information. As such,
- extra care should be taken to review code changes made by this option.
-
- .. code-block:: c++
-
- false: true:
-
- if (isa<FunctionDecl>(D)) vs. if (isa<FunctionDecl>(D)) {
- handleFunctionDecl(D); handleFunctionDecl(D);

-
-.. _InsertTrailingCommas:
-
-**InsertTrailingCommas** (``TrailingCommaStyle``) :versionbadge:`clang-format 11` :ref:`¶ <InsertTrailingCommas>`
- If set to ``TCS_Wrapped`` will insert trailing commas in container
- literals (arrays and objects) that wrap across multiple lines.
- It is currently only available for JavaScript
- and disabled by default ``TCS_None``.
- ``InsertTrailingCommas`` cannot be used together with ``BinPackArguments``
- as inserting the comma disables bin-packing.
-
- .. code-block:: c++
-
- TSC_Wrapped:
- const someArray = [
- aaaaaaaaaaaaaaaaaaaaaaaaaa,
- aaaaaaaaaaaaaaaaaaaaaaaaaa,
- aaaaaaaaaaaaaaaaaaaaaaaaaa,
- // ^ inserted
- ]
-
- Possible values:
-
- * ``TCS_None`` (in configuration: ``None``)
- Do not insert trailing commas.
-
- * ``TCS_Wrapped`` (in configuration: ``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.
-
-
-
-.. _IntegerLiteralSeparator:
-
-**IntegerLiteralSeparator** (``IntegerLiteralSeparatorStyle``) :versionbadge:`clang-format 16` :ref:`¶ <IntegerLiteralSeparator>`
- Format integer literal separators (``'`` for C++ and ``_`` for C#, Java,
- and JavaScript).
-
- Nested configuration flags:
-
- Separator format of integer literals of different bases.
-
- If negative, remove separators. If ``0``, leave the literal as is. If
- positive, insert separators between digits starting from the rightmost
- digit.
-
- For example, the config below will leave separators in binary literals
- alone, insert separators in decimal literals to separate the digits into
- groups of 3, and remove separators in hexadecimal literals.
-
- .. code-block:: c++
-
- IntegerLiteralSeparator:
- Binary: 0
- Decimal: 3
- Hex: -1
-
- You can also specify a minimum number of digits (``BinaryMinDigits``,
- ``DecimalMinDigits``, and ``HexMinDigits``) the integer literal must
- have in order for the separators to be inserted.

-
- 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.
-

-
-**Macros** (``List of Strings``) :versionbadge:`clang-format 17` :ref:`¶ <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:
-
- .. code-block:: c++
-
- 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:
-
- .. code-block:: yaml
-
- 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
-
-
- .. code-block:: c++
-
- A; -> x;
- A(); -> y;
- A(z); -> z;

- 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.

- The number of spaces before trailing line comments
- (``//`` - comments).
-
- This does not affect trailing block comments (``/*`` - comments) as those
- commonly have different usage patterns and a number of special cases. In
- the case of Verilog, it doesn't affect a comment right after the opening

- over the minimum.
-
- .. code-block:: c++
-
- 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

-
- * ``LS_Cpp03`` (in configuration: ``c++03``)
- Parse and format as C++03.
- ``Cpp03`` is a deprecated alias for ``c++03``
-
- * ``LS_Cpp11`` (in configuration: ``c++11``)
- Parse and format as C++11.
-
- * ``LS_Cpp14`` (in configuration: ``c++14``)

-
- * ``LS_Cpp20`` (in configuration: ``c++20``)
- Parse and format as C++20.
-
- * ``LS_Latest`` (in configuration: ``Latest``)
- Parse and format using the latest supported language version.

- Automatic detection based on the input.
-
-
-
-.. _StatementAttributeLikeMacros:
-
-**StatementAttributeLikeMacros** (``List of Strings``) :versionbadge:`clang-format 12` :ref:`¶ <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.
-
- .. code-block:: c++
-
- 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:
-
-**StatementMacros** (``List of Strings``) :versionbadge:`clang-format 8` :ref:`¶ <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
-
-.. _TabWidth:
-
-**TabWidth** (``Unsigned``) :versionbadge:`clang-format 3.7` :ref:`¶ <TabWidth>`
- The number of columns used for tab stops.
-
-.. _TableGenBreakInsideDAGArg:
-
-**TableGenBreakInsideDAGArg** (``DAGArgStyle``) :versionbadge:`clang-format 19` :ref:`¶ <TableGenBreakInsideDAGArg>`
- The styles of the line break inside the DAGArg in TableGen.
-
- Possible values:
-
- * ``DAS_DontBreak`` (in configuration: ``DontBreak``)
- Never break inside DAGArg.
-
- .. code-block:: c++
-
- let DAGArgIns = (ins i32:$src1, i32:$src2);
-
- * ``DAS_BreakElements`` (in configuration: ``BreakElements``)
- Break inside DAGArg after each list element but for the last.
- This aligns to the first element.
-
- .. code-block:: c++
-
- let DAGArgIns = (ins i32:$src1,
- i32:$src2);
-
- * ``DAS_BreakAll`` (in configuration: ``BreakAll``)
- Break inside DAGArg after the operator and the all elements.
-
- .. code-block:: c++
-
- let DAGArgIns = (ins
- i32:$src1,
- i32:$src2
- );
-
-
-
-.. _TableGenBreakingDAGArgOperators:
-
-**TableGenBreakingDAGArgOperators** (``List of Strings``) :versionbadge:`clang-format 19` :ref:`¶ <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,
-
- .. code-block:: yaml
-
- TableGenBreakInsideDAGArg: BreakAll
- TableGenBreakingDAGArgOperators: [ins, outs]
-
- makes the line break only occurs inside DAGArgs beginning with the
- specified identifiers ``ins`` and ``outs``.
-
-
- .. code-block:: c++
-
- let DAGArgIns = (ins
- i32:$src1,
- i32:$src2
- );
- let DAGArgOtherID = (other i32:$other1, i32:$other2);
- let DAGArgBang = (!cast<SomeType>("Some") i32:$src1, i32:$src2)
-
-.. _TemplateNames:
-
-**TemplateNames** (``List of Strings``) :versionbadge:`clang-format 20` :ref:`¶ <TemplateNames>`
- A vector of non-keyword identifiers that should be interpreted as
- template names.
-
- A ``<`` after a template name is annotated as a template opener instead of
- a binary operator.
-
-.. _TypeNames:
-
-**TypeNames** (``List of Strings``) :versionbadge:`clang-format 17` :ref:`¶ <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.
-
-.. _TypenameMacros:
-
-**TypenameMacros** (``List of Strings``) :versionbadge:`clang-format 9` :ref:`¶ <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:
-
- .. code-block:: c++
-
- STACK_OF(...)
-
- In the .clang-format configuration file, this can be configured like:
-
- .. code-block:: yaml
-
- TypenameMacros: [STACK_OF, LIST]
-
- For example: OpenSSL STACK_OF, BSD LIST_ENTRY.
-
-.. _UseCRLF:
-
-**UseCRLF** (``Boolean``) :versionbadge:`clang-format 10` :ref:`¶ <UseCRLF>`
- This option is **deprecated**. See ``LF`` and ``CRLF`` of ``LineEnding``.
-
-.. _UseTab:
-
-**UseTab** (``UseTabStyle``) :versionbadge:`clang-format 3.7` :ref:`¶ <UseTab>`
- The way to use tab characters in the resulting file.
-
- Possible values:
-
- * ``UT_Never`` (in configuration: ``Never``)
- Never use tab.
-
- * ``UT_ForIndentation`` (in configuration: ``ForIndentation``)
- Use tabs only for indentation.
-
- * ``UT_ForContinuationAndIndentation`` (in configuration: ``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`` (in configuration: ``AlignWithSpaces``)
- Use tabs for line continuation and indentation, and spaces for
- alignment.
-
- * ``UT_Always`` (in configuration: ``Always``)
- Use tabs whenever we need to fill whitespace that spans at least from
- one tab stop to the next one.
-
-
-
-.. _VerilogBreakBetweenInstancePorts:
-
-**VerilogBreakBetweenInstancePorts** (``Boolean``) :versionbadge:`clang-format 17` :ref:`¶ <VerilogBreakBetweenInstancePorts>`
- For Verilog, put each port on its own line in module instantiations.
-
- .. code-block:: c++
-
- true:
- ffnand ff1(.q(),
- .qbar(out1),
- .clear(in1),
- .preset(in2));
-
- false:
- ffnand ff1(.q(), .qbar(out1), .clear(in1), .preset(in2));
-
-.. _WhitespaceSensitiveMacros:
-
-**WhitespaceSensitiveMacros** (``List of Strings``) :versionbadge:`clang-format 11` :ref:`¶ <WhitespaceSensitiveMacros>`
- A vector of macros which are whitespace-sensitive and should not
- be touched.
-
- These are expected to be macros of the form:
-
- .. code-block:: c++
-
- STRINGIZE(...)
-
- In the .clang-format configuration file, this can be configured like:
-
- .. code-block:: yaml
-
- WhitespaceSensitiveMacros: [STRINGIZE, PP_STRINGIZE]
-
- For example: BOOST_PP_STRINGIZE
-
