Yitzhak Mandelbaum 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.

Patch by Eric Li.

This patch makes cases work where the lambda's template list doesn't
contain any of + - ! ~ / % << | || && ^ == != >= <= ? : true false

Paul Hoad 719087bbb7 [clang-format] [PR43100] clang-format C# support does not add a space between "using" and paren
Summary:
Addresses https://bugs.llvm.org/show_bug.cgi?id=43100

Formatting using statement in C# with clang-format removes the space between using and paren even when SpaceBeforeParens is !

```
using(FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read, bufferSize : 1))
```

this change simply overcomes this for when using C# settings in the .clang-format file

```
using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read, bufferSize : 1))
```

All FormatTests pass..

```

The reason being that the parser expects a token after `#elif`, and the
subsequent parsing of the next line does not check if `CurrentToken` is null.

Nico Weber 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.

Ben Hamilton 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++.)

Sam McCall 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.

Francois Ferrand 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.

Krasimir Georgiev bda8482aba [clang-format] Fix indent of trailing raw string param after newline
Summary:
Currently clang-format uses ContinuationIndent to indent the contents of a raw
string literal that is the last parameter of the function call. This is to
achieve formatting similar to trailing:
```
f(1, 2, R"pb(
    x: y)pb");
```
However this had the unfortunate consequence of producing format like this:
```
fffffff(1, 2,
        R"pb(
    a: b
        )pb");
```

This patch makes clang-format consider indenting a trailing raw string param
after a newline based off the start of the format delimiter, producing:
```
fffffff(1, 2,
        R"pb(
          a: b
        )pb");
```

Krasimir Georgiev 925bb20c79 [clang-format] Do not emit replacements while regrouping if Cpp includes are OK
Summary:
Currently clang-format would always emit a replacement for multi-block #include
sections if `IBS_Regroup`, even if the sections are correct:
```
% cat ~/test.h
#include <a.h>

#include "b.h"
% bin/clang-format --output-replacements-xml -style=google ~/test.h
<?xml version='1.0'?>
<replacements xml:space='preserve' incomplete_format='false'>
<replacement offset='0' length='30'>#include &lt;a.h>&#10;&#10;#include "b.h"</replacement>
</replacements>
%
```

This change makes clang-format not emit replacements in this case.
The logic is similar to the one implemented for Java in r354452.

Summary:
Regrouping #includes in blocks separated by blank lines when sorting C++ #include
headers was implemented recently, and it has been preferred in Google's C++ style guide:

Paul Hoad 88335c21a4 [clang-format] [PR41187] moves Java import statements to the wrong location if code contains statements that start with the word import
Summary:
Import sorting of java file, incorrectly move import statement to after a function beginning with the word import.

Make 1 character change to regular expression to ensure there is always at least one space/tab after the word import

Previously clang-format --style="LLVM" would format

```
import X;

class C {
  void m() {
    importFile();
  }
}
```
as

```
class C {
  void m() {
    importFile();
import X;
  }
}
```

Reuben Thomas 08a940d629 [clang-format]: Add NonEmptyParentheses spacing option
This patch aims to add support for the following rules from the JUCE coding standards:

- Always put a space before an open parenthesis that contains text - e.g. foo (123);
- Never put a space before an empty pair of open/close parenthesis - e.g. foo();
