375a84bb75 [clang-format] SpacesInSquareBrackets should affect lambdas with parameters too
Summary:
This patch makes the `SpacesInSquareBrackets` setting also apply to C++ lambdas with parameters.

Looking through the revision history, it appears support for only array brackets was added, and lambda brackets were ignored. Therefore, I am inclined to think it was simply an omission, rather than a deliberate choice.

See https://bugs.llvm.org/show_bug.cgi?id=17887 and https://reviews.llvm.org/D4944.

cccf5aa081 [clang-format] C++11 braced lists should respect the SpacesInParentheses setting
Summary:
According to the clang-format documentation, "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."

This patch furthers the treatment of C++11 braced list braces as parentheses by respecting the `SpacesInParentheses` setting.

ba12cec21f [clang-format] [PR43531] clang-format damages "alternative representations" for operators
Summary:
https://bugs.llvm.org/show_bug.cgi?id=43531

Fix for clang-format incorrectly handles "alternative operators" as described by https://en.cppreference.com/w/cpp/language/operator_alternative

compl = ~
not = !

these are unary operators, and clang-format will remove the space between them and a numeric constant

this incorrectly formats the following code

```
int a compl 5;
int a not 5;
```

into:

```
int a compl5;
int a not5;
```

The code adds FIXME unit tests for "alternative token" representations for {} [] and # as defined by the same link, which would require a more detailed change to the FormatTokenLexer

4c05658354 [clang-format] [PR43338] C# clang format has space issues betweern C# only keywords
Summary:
When formatting C# there can be issues with a lack of spaces between `using (` , `foreach (` and generic types

The C# code

```
public class Foo
{
    Dictionary<string,string> foo;
}

```
will be formatted as

```
public class Foo
{
    Dictionary<string, string>foo;
                           ^^^^^   missing a space
}
```

This revision also reverts some of {D66662} in order to make this cleaner and resolve an issues seen by @owenpan that the formatting didn't add a space when not in a code block

This also transforms C# foreach commands to be seen as tok::kw_for commands (to ensure foreach gets the same Brace Wrapping behavior as for without littering the code with `if(Style.isCSharp())`

Summary:
This is  a fix for https://bugs.llvm.org/show_bug.cgi?id=43333

This comes with 3 main parts

  - C# attributes cause function names on a new line even when AlwaysBreakAfterReturnType is set to None
  - Add AlwaysBreakAfterReturnType  to None by default in the Microsoft style,
  - C# unit tests are not using Microsoft style (which we created to define the default C# style to match a vanilla C# project).

fb13e65acf [clang-format] Add ability to wrap braces after multi-line control statements
Summary:
Change the BraceWrappingFlags' AfterControlStatement from a bool to an enum with three values:

* "Never": This is the default, and does not do any brace wrapping after control statements.
* "MultiLine": This only wraps braces after multi-line control statements (this really only happens when a ColumnLimit is specified).
* "Always": This always wraps braces after control statements.

The first and last options are backwards-compatible with "false" and "true", respectively.

The new "MultiLine" option is useful for when a wrapped control statement's indentation matches the subsequent block's indentation. It makes it easier to see at a glance where the control statement ends and where the block's code begins. For example:

```
if (
  foo
  && bar )
{
  baz();
}
```

vs.

```
if (
  foo
  && bar ) {
  baz();
}
```

Short control statements (1 line) do not wrap the brace to the next line, e.g.

```
if (foo) {
  bar();
} else {
  baz();
}
```

e503256790 [ClangFormat] Future-proof Standard option, allow floating or pinning to arbitrary lang version
Summary:
The historical context:
- clang-format was written when C++11 was current,
  and the main language-version concern was >> vs > > template-closers.
  An option was added to allow selection of the 03/11 behavior, or auto-detection.
- there was no option to choose simply "latest standard" so anyone who didn't
  ever want 03 behavior or auto-detection specified Cpp11.
- In r185149 this option started to affect lexer mode.
- no options were added to cover c++14, as parsing/formatting
  didn't change that much. The usage of Cpp11 to mean "latest" became
  codified e.g. in r206263
- c++17 added some new constructs. These were mostly backwards-compatible and so
  not used in old programs, so having no way to turn them off was OK.
- c++20 added some new constructs and keywords (e.g. co_*) that changed the
  meaning of existing programs, and people started to complain that
  the c++20 parsing couldn't be turned off.

New plan:
 - Default ('Auto') behavior remains unchanged: parse as latest, format
   template-closers based on input.
 - Add new 'Latest' option that more clearly expresses the intent "use
   modern features" that many projects have chosen for their .clang-format files.
 - Allow pinning to *any* language version, using the same name as clang -std:
   c++03, c++11, c++14 etc. These set precise lexer options, and any
   clang-format code depending on these can use a >= check.
 - For backwards compatibility, `Cpp11` is an alias for `Latest`, not `c++11`.
   This matches the historical documented semantics of this option.
   This spelling (and `Cpp03`) are deprecated.

603650213b [clang-format] [PR43372] - clang-format shows replacements in DOS files when no replacement is needed
Summary:
This is a patch to fix PR43372 (https://bugs.llvm.org/show_bug.cgi?id=43372) - clang-format can't format file with includes, ( which really keep providing replacements for already sorted headers.)

A similar issue was addressed by @krasimir in {D60199}, however, this seemingly only prevented the issue when the files being formatted did not contain windows line endings (\r\n)

It's possible this is related to https://twitter.com/StephanTLavavej/status/1176722938243895296 given who @STL_MSFT  works for!

As people often used the existence of replacements to determine if a file needs clang-formatting, this is probably pretty important for windows users

There may be a better way of comparing 2 strings and ignoring \r (which appear in both Results and Code), I couldn't choose between this idiom or the copy_if approach, but I'm happy to change it to whatever people consider more performant.

52e44b1423 [clang-format] Modified SortIncludes and IncludeCategories to priority for sorting #includes within the Group Category.
Summary:
This new Style rule is made as a part of adding support for NetBSD KNF in clang-format. NetBSD have it's own priority of includes which should be followed while formatting NetBSD code. This style sorts the Cpp Includes according to the priorities of NetBSD, as mentioned in the [Style Guide](http://cvsweb.netbsd.org/bsdweb.cgi/src/share/misc/style?rev=HEAD&content-type=text/x-cvsweb-markup)
 The working of this Style rule shown below:

**Configuration:**
This revision introduces a new field under IncludeCategories named `SortPriority` which defines the priority of ordering the `#includes` and the `Priority` will define the categories for grouping the `#include blocks`.

45b6ca5cd6 [clang-format] Fix cleanup of AnnotatedLine to include children nodes.
Summary:
AnnotatedLine has a tree structure, and things like the body of a lambda will be
a child of the lambda expression. For example,

    [&]() { foo(a); };

will have an AnnotatedLine with a child:

    [&]() {};
     '- foo(a);

Currently, when the `Cleaner` class analyzes the affected lines, it does not
cleanup the lines' children nodes, which results in missed cleanup
opportunities, like the lambda body in the example above.

This revision extends the algorithm to visit children, thereby fixing the above problem.

1361a4c2d8 clang-format: Support if CONSTEXPR if CONSTEXPR is a macro.
This is like r305666 (which added support for `if constexpr`) except
that it allows a macro name after the if.

This is slightly tricky for two reasons:

1. r305666 didn't add test coverage for all cases where it added a
   kw_constexpr, so I had to figure out what all the added cases were
   for. I now added tests for all `if constexpr` bits that didn't have
   tests. (This took a while, see e.g. https://reviews.llvm.org/D65223)

2. Parsing `if <ident> (` as an if means that `#if defined(` and
   `#if __has_include(` parse as ifs too. Add some special-case code
   to prevent this from happening where it's incorrect.

Fixes PR39248.

00e8ac3beb [Format] Make it easy to add new format::FormatStyle::LanguageStandard. NFCI
Preparatory change for D65043.

We current use `!=LS_Cpp03` to enable language standards 11,14,17, and
2a. `>=LS_Cpp11` is better if we decide to add new LanguageStandard in
the future.

37944130f9 clang-format: Fix namespace end comments for namespaces with attributes and macros.
Fixes PR39247.

While here, also make C++20 `namespace A::inline B::inline C` nested
inline namespaced definitions work.

Before:
    #define DEPRECATE_WOOF [[deprecated("meow")]]

    namespace DEPRECATE_WOOF woof {
    void f() {}
    } // namespace DEPRECATE_WOOFwoof

    namespace [[deprecated("meow")]] woof {
      void f() {}
    } // namespace [[deprecated("meow")]]woof

    namespace woof::inline bark {
      void f() {}
    } // namespace woof::inlinebark

Now:
    #define DEPRECATE_WOOF [[deprecated("meow")]]

    namespace DEPRECATE_WOOF woof {
    void f() {}
    } // namespace woof

    namespace [[deprecated("meow")]] woof {
    void f() {}
    } // namespace woof

    namespace woof::inline bark {
    void f() {}
    } // namespace woof::inline bark

(In addition to the fixed namespace end comments, also note the correct
indent of the namespace contents.)

d9212ef77b Adds support for formatting NS_CLOSED_ENUM and CF_CLOSED_ENUM alongside NS_ENUM and CF_ENUM.
Summary:
Addresses the formatting of NS_CLOSED_ENUM and CF_CLOSED_ENUM, introduced in Swift 5.

Before:

```
typedef NS_CLOSED_ENUM(NSInteger, Foo){FooValueOne = 1, FooValueTwo,
                                       FooValueThree};
```

After:

```
typedef NS_CLOSED_ENUM(NSInteger, Foo) {
  FooValueOne = 1,
  FooValueTwo,
  FooValueThree
};
```

f4c2d57f76 [clang-format] Don't detect call to ObjC class method as C++11 attribute specifier
Summary:
Previously, clang-format detected something like the following as a C++11 attribute specifier.

  @[[NSArray class]]

instead of an array with an Objective-C method call inside. In general, when the attribute specifier checking runs, if it sees 2 identifiers in a row, it decides that the square brackets represent an Objective-C method call. However, here, `class` is tokenized as a keyword instead of an identifier, so this check fails.

To fix this, the attribute specifier first checks whether the first square bracket has an "@" before it. If it does, then that square bracket is not the start of a attribute specifier because it is an Objective-C array literal. (The assumption is that @[[.*]] is not valid C/C++.)

04ee232ff2 clang-format: Add new style option AlignConsecutiveMacros
This option behaves similarly to AlignConsecutiveDeclarations and
AlignConsecutiveAssignments, aligning the assignment of C/C++
preprocessor macros on consecutive lines.

I've worked in many projects (embedded, mostly) where header files full
of large, well-aligned "#define" blocks are a common pattern. We
normally avoid using clang-format on these files, since it ruins any
existing alignment in said blocks. This style option will align "simple"
PP macros (no parameters) and PP macros with parameter lists on
consecutive lines.

e8a301f87f clang-format: better handle namespace macros
Summary:
Other macros are used to declare namespaces, and should thus be handled
similarly. This is the case for crpcut's TESTSUITE macro, or for
unittest-cpp's SUITE macro:

      TESTSUITE(Foo) {
      TEST(MyFirstTest) {
        assert(0);
      }
      } // TESTSUITE(Foo)

This patch deals with this cases by introducing a new option to specify
lists of namespace macros. Internally, it re-uses the system already in
place for foreach and statement macros, to ensure there is no impact on
performance.

c5227a1f53 [clang-format] Allow configuring list of function-like macros that resolve to a type
Summary:
Adds a `TypenameMacros` configuration option that causes certain identifiers to be handled in a way similar to `typeof()`.

This is enough to:
- Prevent misinterpreting declarations of pointers to such types as expressions (`STACK_OF(int) * foo` -> `STACK_OF(int) *foo`),
- Avoid surprising line breaks in variable/struct field declarations (`STACK_OF(int)\nfoo;` -> `STACK_OF(int) foo;`, see https://bugs.llvm.org/show_bug.cgi?id=30353).
