mydeveloperday 2e7add812e [clang-format] Add a option for the position of Java static import
Some Java style guides and IDEs group Java static imports after
 non-static imports. This patch allows clang-format to control
 the location of static imports.

Alex Richardson e7bd058c7e [clang-format] Allow configuring list of macros that map to attributes
This adds a `AttributeMacros` configuration option that causes certain
identifiers to be parsed like a __attribute__((foo)) annotation.
This is motivated by our CHERI C/C++ fork which adds a __capability
qualifier for pointer/reference. Without this change clang-format parses
many type declarations as multiplications/bitwise-and instead.
I initially considered adding "__capability" as a new clang-format keyword,
but having a list of macros that should be treated as attributes is more
flexible since it can be used e.g. for static analyzer annotations or other language
extensions.

Example: std::vector<foo * __capability> -> std::vector<foo *__capability>

Depends on D86775 (to apply cleanly)

Anders Waldenborg 52ab7aa0ba [clang-format] Add BitFieldColonSpacing option

BitFieldColonSpacing accepts four different values:

  // "Both" - default
  unsigned bitfield : 5
  unsigned bf2      : 5  // AlignConsecutiveBitFields=true

  // "None"
  unsigned bitfield:5
  unsigned bf2     :5

Jake Merdich 0c332a7784 [clang-format] Preserve whitespace in selected macros
Summary:
https://bugs.llvm.org/show_bug.cgi?id=46383

When the c preprocessor stringizes tokens, the generated string literals
are affected by the whitespace. This means clang-format can affect
codegen silently, adding spaces and newlines to strings.  Practically
speaking, the vast majority of cases will be harmless, only affecting
single identifiers or debug macros.

In the interest of doing no harm in other cases though, this introduces
a blacklist option 'WhitespaceSensitiveMacros', which contains a list of
names of function-like macros whose contents should not be touched by
clang-format, period. Clang-format can't automatically detect these
without a real compile context, so users will have to specify it
explicitly (it still beats clang-format off'ing at every invocation).

Defaults include "STRINGIZE", "PP_STRINGIZE", and "BOOST_PP_STRINGIZE".

mydeveloperday b99bf0e08b [clang-format][PR45816] Add AlignConsecutiveBitFields
Summary:
The following revision follows D80115 since @MyDeveloperDay and I apparently both had the same idea at the same time, for https://bugs.llvm.org/show_bug.cgi?id=45816 and my efforts on tooling support for AMDVLK, respectively.

This option aligns adjacent bitfield separators across lines, in a manner similar to AlignConsecutiveAssignments and friends.

Example:
```
struct RawFloat {
  uint32_t sign : 1;
  uint32_t exponent : 8;
  uint32_t mantissa : 23;
};
```
would become
```
struct RawFloat {
  uint32_t sign     : 1;
  uint32_t exponent : 8;
  uint32_t mantissa : 23;
};
```

This also handles c++2a style bitfield-initializers with AlignConsecutiveAssignments.
```
struct RawFloat {
  uint32_t sign     : 1  = 0;
  uint32_t exponent : 8  = 127;
  uint32_t mantissa : 23 = 0;
}; // defaults to 1.0f
```

Things this change does not do:
 - Align multiple comma-chained bitfield variables. None of the other
   AlignConsecutive* options seem to implement that either.
 - Detect bitfields that have a width specified with something other
   than a numeric literal (ie, `int a : SOME_MACRO;`). That'd be fairly
   difficult to parse and is rare.

Daan De Meyer f21c704553 clang-format: Add ControlStatementsExceptForEachMacros option to SpaceBeforeParens
Summary: systemd recently added a clang-format file. One issue I
encountered in using clang-format on systemd is that systemd does
not add a space before the parens of their foreach macros but
clang-format always adds a space. This does not seem to be
configurable in clang-format. This revision adds the
ControlStatementsExceptForEachMacros option to SpaceBeforeParens
which puts a space before all control statement parens except
ForEach macros. This drastically reduces the amount of changes
when running clang-format on systemd's source code.

While [the original diff](https://reviews.llvm.org/D42493) makes a lot of sense, and multiple inline block parameter/trailing paramemter after inline block paramemter should be discouraged, the formatting result is different than what xcode does by default
For the exact same example provided in the original diff:
```
[object
  blockArgument:^{
    a = 42;
  }
     anotherArg:42];
```
The code is hard to read and not very visually pleasing

This diff uses `ObjCBreakBeforeNestedBlockParam` to shield from the formatting
When it's set to false, don't allign the inline block paramemters.

mydeveloperday 70c98671fa [clang-format] Add option for not breaking line before ObjC params
Summary:
From `clang-format` version 3.7.0 and up, , there is no way to keep following format of ObjectiveC block:
```
- (void)_aMethod
{
    [self.test1 t:self w:self callback:^(typeof(self) self, NSNumber *u, NSNumber *v) {
        u = c;
    }]
}
```
Regardless of the change in `.clang-format` configuration file, all parameters will be lined up so that colons will be on the same column, like following:
```
- (void)_aMethod
{
    [self.test1 t:self
                w:self
         callback:^(typeof(self) self, NSNumber *u, NSNumber *v) {
             u = c;
         }]
}
```

Considering with ObjectiveC, the first code style is cleaner & more readable for some people, I've added a config option: `ObjCDontBreakBeforeNestedBlockParam` (boolean) so that if it is enable, the first code style will be favored.

mydeveloperday 14c044756e [clang-format] Add IndentCaseBlocks option
Summary:
The documentation for IndentCaseLabels claimed that the "Switch
statement body is always indented one level more than case labels". This
is technically false for the code block immediately following the label.
Its closing bracket aligns with the start of the label.

If the case label are not indented, it leads to a style where the
closing bracket of the block aligns with the closing bracket of the
switch statement, which can be hard to parse.

This change introduces a new option, IndentCaseBlocks, which when true
treats the block as a scope block (which it technically is).

(Note: regenerated ClangFormatStyleOptions.rst using tools/dump_style.py)

paulhoad eadb65f273 [clang-format] [NFC] update the documentation in Format.h to allow dump_format_style.py to get a little closer to being correct. (part 2)
Summary:
a change {D67541} cause LanguageStandard to now be subtly different from all other clang-format options, in that the Enum value (less the prefix) is not always allowed as valid as the configuration option.

This caused the ClangFormatStyleOptions.rst and the Format.h to diverge so that the ClangFormatStyleOptions.rst could no longer be generated from the Format.h using dump_format_stlye.py

This fix tried to remedy that:

1) by allowing an additional comment (in Format.h) after the enum to be used as the `in configuration ( XXXX )`  text, and changing the dump_format_style.py to support that.

This makes the following code:

```
enum {
...
LS_Cpp03, // c++03
LS_Cpp11, // c++11
...
};
```

would render as:

```* ``LS_Cpp03`` (in configuration: ``c++03``)
* ``LS_Cpp11`` (in configuration: ``c++11``)
```

And we also  move the deprecated alias into the text of the enum (otherwise it won't be added at the end as an option)

This patch includes a couple of other whitespace changes which help bring Format.h and ClangFormatStyleOptions.rst almost back into line and regeneratable...  (there is still one more)

Paul Hoad 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();
}
```

Sam McCall 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.

Paul Hoad 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`.

There are still some issues with this patch, primarily around `switch` and `case` support. The added unit test won’t currently pass because of the remaining issues.

Summary:

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.

Paul Hoad cbb726d0c5 [clang-format] Add basic support for formatting C# files
Summary:

This revision adds basic support for formatting C# files with clang-format, I know the barrier to entry is high here  so I'm sending this revision in to test the water as to whether this might be something we'd consider landing.

Tracking in Bugzilla as:
https://bugs.llvm.org/show_bug.cgi?id=40850

Justification:
C# code just looks ugly in comparison to the C++ code in our source tree which is clang-formatted.

I've struggled with Visual Studio reformatting to get a clean and consistent style, I want to format our C# code on saving like I do now for C++ and i want it to have the same style as defined in our .clang-format file, so it consistent as it can be with C++.  (Braces/Breaking/Spaces/Indent etc..)

Using clang format without this patch leaves the code in a bad state, sometimes when the BreakStringLiterals is set, it  fails to compile.

Mostly the C# is similar to Java, except instead of JavaAnnotations I try to reuse the TT_AttributeSquare.

Almost the most valuable portion is to have a new Language in order to partition the configuration for C# within a common .clang-format file, with the auto detection on the .cs extension. But there are other C# specific styles that could be added later if this is accepted. in particular how  `{ set;get }` is formatted.

Summary:
Some macros are used in the body of function, and actually contain the trailing semicolon: they should thus be automatically followed by a new line, and not get merged with the next line. This is for example the case with Qt's Q_UNUSED macro:

    Q_UNUSED(a)
    return b;
  }

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

Krasimir Georgiev d6ce937f49 [clang-format] New flag - BraceWrapping.AfterExternBlock
Summary:
Bug: https://bugs.llvm.org/show_bug.cgi?id=34016 - **"extern C part"**

**Problem:**

Due to the lack of "brace wrapping extern" flag, clang format does parse the block after **extern** keyword moving the opening bracket to the header line always!

**Patch description:**

A new style added, new configuration flag - **BraceWrapping.AfterExternBlock** that allows us to decide whether we want a break before brace or not.

Daniel Jasper 392c2ba675 [clang-format] Fix documentation for AllowAllParametersOfDeclarationOnNextLine
The current description of AllowAllParametersOfDeclarationOnNextLine in
the Clang-Format Style Options guide suggests that it is possible to
format function declaration, which fits in a single line (what is not
supported in current clang-format version). Also the example was not
reproducible and mades no sense.

Krasimir Georgiev ad47c90767 clang-format: Add preprocessor directive indentation
Summary:
This is an implementation for [bug 17362](https://bugs.llvm.org/attachment.cgi?bugid=17362) which adds support for indenting preprocessor statements inside if/ifdef/endif. This takes previous work from fmauch (https://github.com/fmauch/clang/tree/preprocessor_indent) and makes it into a full feature.
The context of this patch is that I'm a VMware intern, and I implemented this because VMware needs the feature. As such, some decisions were made based on what VMware wants, and I would appreciate suggestions on expanding this if necessary to use-cases other people may want.

This adds a new enum config option, `IndentPPDirectives`. Values are:

* `PPDIS_None` (in config: `None`):
```
    #if FOO
    #if BAR
    #include <foo>
    #endif
    #endif
```
* `PPDIS_AfterHash` (in config: `AfterHash`):
```
    #if FOO
    #  if BAR
    #    include <foo>
    #  endif
    #endif
```
This is meant to work whether spaces or tabs are used for indentation. Preprocessor indentation is independent of indentation for non-preprocessor lines.

Preprocessor indentation also attempts to ignore include guards with the checks:
1. Include guards cover the entire file
2. Include guards don't have `#else`
3. Include guards begin with
```
#ifndef <var>
#define <var>
```

This patch allows `UnwrappedLineParser::PPBranchLevel` to be decremented to -1 (the initial value is -1) so the variable can be used for indent tracking.

Defects:
* This patch does not handle the case where there's code between the `#ifndef` and `#define` but all other conditions hold. This is because when the #define line is parsed, `UnwrappedLineParser::Lines` doesn't hold the previous code line yet, so we can't detect it. This is out of the scope of this patch.

* This patch does not handle cases where legitimate lines may be outside an include guard. Examples are `#pragma once` and `#pragma GCC diagnostic`, or anything else that does not change the meaning of the file if it's included multiple times.

* This does not detect when there is a single non-preprocessor line in front of an include-guard-like structure where other conditions hold because `ScopedLineState` hides the line.

* Preprocessor indentation throws off `TokenAnnotator::setCommentLineLevels` so the indentation of comments immediately before indented preprocessor lines is toggled on each run. Fixing this issue appears to be a major change and too much complexity for this patch.
