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:
Sometime after 6.0.0 and the current trunk 9.0.0 the following code would be considered as objective C and not C++
Reported by: https://twitter.com/mattgodbolt/status/1096188576503644160
$ clang-format.exe test.h
Configuration file(s) do(es) not support Objective-C: C:\clang\build\.clang-format
--- test.h --
```
std::vector<std::pair<std::string,std::string>> C;
void foo()
{
for (auto && [A,B] : C)
{
std::string D = A + B;
}
}
```
The following code fixes this issue of incorrect detection

Before:
const x = veryLongIdentifier
`hello`;
After:
const x =
veryLongIdentifier`hello`;
While it's allowed to have the template string and tag identifier
separated by a line break, currently the clang-format output is not
stable when a break is forced. Additionally, disallowing a line break
makes it clear that the identifier is actually a tag for a template
string.

Summary:
Currently, `UnwrappedLineParser` thinks an arrow token after
an ObjC method expression is a C++ lambda arrow, so it formats:
```
[foo bar]->baz
```
as:
```
[foo bar] -> baz
```
Because `UnwrappedLineParser` runs before `TokenAnnotator`, it can't
know if the arrow token is after an ObjC method expression or not.
This diff makes `TokenAnnotator` remove the TT_LambdaArrow on
the arrow token if it follows an ObjC method expression.
Test Plan: New test added. Ran test with:
% ninja FormatTests && ./tools/clang/unittests/Format/FormatTests
Confirmed test failed before diff and passed after diff.

What was happening is that the split penalty before `operator` was being set to
a smaller value by a prior if block. Moved checks around to fix this and added a
regression test.

The commit r322690 introduced support for ObjC detection in header files.
Unfortunately some C headers that use designated initializers are now
incorrectly detected as Objective-C.
This commit fixes it by ensuring that `[ token ]` is not annotated as an
Objective-C message send.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
r346756 refined clang-format to not treat the `[` in `asm (...: [] ..)` as an
ObjCExpr. However that's not enough, as we might have a comma-separated list of
such clobbers as in the newly added test.
This updates the detection to instead look at the Line's first token being `asm`
and not mark `[`-s as ObjCExprs in this case.

Summary:
clang-format can get confused by string literals in TableGen: it knows that strings can be broken up, but doesn't seem to understand how that can be indented across line breaks, and arranges them in a weird triangular pattern. Take this output example from `clang-format tools/llvm-objcopy/ObjcopyOpts.td` (which has now been formatted in rL345896 with this patch applied):
```
defm keep_global_symbols
: Eq<
"keep-global-symbols", "Reads a list of symbols from <filename> and "
"runs as if " "--keep-global-symbol=<symbol> "
"is set for each one. "
"<filename> " "contains one "
"symbol per line "
"and may contain "
"comments "
"beginning " "with"

Summary:
The issue is that for array subscript like:
```
arr[[Foo() bar]];
```
ClangFormat will recognize it as C++11 attribute syntax and put a space between 'arr' and first '[', like:
```
arr [[Foo() bar]];
```
Now it is fixed. Tested with:

Summary:
This is done in order to improve cases where the lambda's body is moved too far to the right. Consider the following snippet with column limit set to 79:
```
void f() {
leader::MakeThisCallHere(&leader_service_,
cq_.get(),
[this, liveness](const leader::ReadRecordReq& req,
std::function<void()> done) {
logger_->HandleReadRecord(
req, resp, std::move(done));
});
leader::MakeAnother(&leader_service_,
cq_.get(),
[this, liveness](const leader::ReadRecordReq& req,
std::function<void()> done) {
logger_->HandleReadRecord(
req, resp, std::move(done), a);
});
}
```
The tool favors extra indentation for the lambda body and so the code incurs extra wrapping and adjacent calls are indented to a different level. I find this behavior annoying and I'd like the tool to favor new lines and, thus, use the extra width.
The fix, reduced, brings the following formatting.
Before:
function(1,
[] {
DoStuff();
//
},
1);
After:
function(
1,
[] {
DoStuff();
//
},
1);

The existing code kept the space if it was there for identifiers, and it didn't
handle `this`. After this patch, for Java `this` is handled in addition to
identifiers, and existing space is always stripped between identifier and `::`.
Also accept `::` in addition to `.` in front of `<` in `foo::<T>bar` generic
calls.

Summary:
This change adds some rudimentary support for conditional types.
Specifically it avoids breaking before `extends` and `infer` keywords,
which are subject to Automatic Semicolon Insertion, so breaking before
them creates incorrect syntax.
The actual formatting of the type expression is odd, but there is as of
yet no clear idea on how to format these.
See https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-8.html#conditional-types.

Reduce penalty for aligning ObjC method arguments using the colon alignment as
this is the canonical way.
Trying to fit a whole expression into one line should not force other line
breaks (e.g. when ObjC method expression is a part of other expression).

Summary:
In D44638, I partially fixed `NS_SWIFT_NAME(foo(bar:baz:))`-style
annotations on C functions, but didn't add a test for Objective-C
method declarations.
For ObjC method declarations which are annotated with `NS_SWIFT_NAME(...)`,
we currently fail to annotate the final component of the selector
name as `TT_SelectorName`.
Because the token type is left unknown, clang-format will happily
cause a compilation error when it changes the following:
```
@interface Foo
- (void)doStuffWithFoo:(id)name
bar:(id)bar
baz:(id)baz
NS_SWIFT_NAME(doStuff(withFoo:bar:baz:));
@end
```
to:
```
@interface Foo
- (void)doStuffWithFoo:(id)name
bar:(id)bar
baz:(id)baz
NS_SWIFT_NAME(doStuff(withFoo:bar:baz
:));
@end
```
(note the linebreak before the final `:`).
The logic which decides whether or not to annotate the token before a
`:` with `TT_SelectorName` is pretty fragile, and has to handle some
pretty odd cases like pair-parameters:
```
[I drawRectOn:surface ofSize:aa:bbb atOrigin:cc:dd];
```
So, to minimize the effect of this change, I decided to only annotate
unknown identifiers before a `:` as `TT_SelectorName` for Objective-C
declaration lines.
Test Plan: New tests included. Confirmed tests failed before change and
passed after change. Ran tests with:
% make -j16 FormatTests && ./tools/clang/unittests/Format/FormatTests

WebKit C++ style for object initialization is as follows:
Foo foo { bar };
Yet using clang-format -style=webkit changes this to:
Foo foo{ bar };
As there is no existing combination of rules that will ensure a space
before a braced list in this fashion, this patch adds a new
SpaceBeforeCpp11BracedList rule.

Summary:
Currently clang-format allows this for text protos:
```
submessage:
{ key: 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa' }
```
when it is under the column limit and when putting it all on one line exceeds the column limit.
This is not a very intuitive formatting, so I'd prefer having
```
submessage: {
key: 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'
}
```
instead, even if it takes one line more.
This patch prevents clang-format from inserting a break between `: {` and similar cases.

Summary:
TypeScript uses the `!` token for strict property initialization
assertions, as in:

Previously, clang-format would wrap between the `!` and the `:` for
overly long lines. This patch fixes that by generally preventing the
wrap in that location.

Summary:
This option replaces the BreakBeforeInheritanceComma option with an
enum, thus introducing a mode where the colon stays on the same line as
constructor declaration:
// When it fits on line:
class A : public B, public C {
...
};
// When it does not fit:
class A :
public B,
public C {
...
};
This matches the behavior of the `BreakConstructorInitializers` option,
introduced in https://reviews.llvm.org/D32479.

submessage
Summary:
This patch updates clang-format text protos to put entries of a submessage into separate lines if the submessage contains at least two entries and contains at least one submessage entry.
For example, the entries here are kept on separate lines even if putting them on a single line would be under the column limit:
```
message: {
entry: 1
submessage: { key: value }
}
```
Messages containing a single submessage or several scalar entries can still be put on one line if they fit:
```
message { submessage { key: value } }
message { x: 1 y: 2 z: 3 }
```

}
Breaking before the `is` above breaks TypeScript parsing the code. This

Summary:
Previously, clang-format's parser would fail to annotate the
selector in a single-component Objective-C method invocation with
`TT_SelectorName`. For example, the following:
[foo bar];
would parse `bar` as `TT_Unknown`:
M=0 C=1 T=Unknown S=0 B=0 BK=0 P=140 Name=identifier L=34 PPK=2
FakeLParens= FakeRParens=0 II=0x559d5db51770 Text='bar'
This caused us to fail to insert a space after a closing cast rparen,
so the following:
[((Foo *)foo) bar];
would format as:
[((Foo *)foo)bar];
This diff fixes the issue by ensuring we annotate the selector
in a single-component Objective-C method invocation as
`TT_SelectorName`.

Summary:
Introduce `PenaltyBreakTemplateDeclaration` to control the penalty,
and change `AlwaysBreakTemplateDeclarations` to an enum with 3 modes:
* `No` for regular, penalty based, wrapping of template declaration
* `MultiLine` for always wrapping before multi-line declarations (e.g.
same as legacy behavior when `AlwaysBreakTemplateDeclarations=false`)
* `Yes` for always wrapping (e.g. same as legacy behavior when
`AlwaysBreakTemplateDeclarations=true`)

Summary:
This patch changes the behavior of PenaltyBreakBeforeFirstCallParameter
so that is does not apply after a brace, when Cpp11BracedListStyle is
false.
This way, variable initialization is wrapped more like an initializer
than like a function call, which is more consistent with user
expectations for this braced list style.
With PenaltyBreakBeforeFirstCallParameter=200, this gives the following
code: (with Cpp11BracedListStyle=false)
Before :
const std::unordered_map<std::string, int> Something::MyHashTable =
{ { "aaaaaaaaaaaaaaaaaaaaa", 0 },
{ "bbbbbbbbbbbbbbbbbbbbb", 1 },
{ "ccccccccccccccccccccc", 2 } };
After :
const std::unordered_set<std::string> Something::MyUnorderedSet = {
{ "aaaaaaaaaaaaaaaaaaaaa", 0 },
{ "bbbbbbbbbbbbbbbbbbbbb", 1 },
{ "ccccccccccccccccccccc", 2 }
};

The DEBUG() macro is very generic so it might clash with other projects.
The renaming was done as follows:
- git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g'
- git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM
Explicitly avoided changing the strings in the clang-format tests.

This is similar to the LLVM change https://reviews.llvm.org/D46290.
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Summary:
Previously, we checked tokens for `tok::identifier` to see if they
were identifiers inside an Objective-C selector.
However, this missed C++ keywords like `new` and `delete`.
To fix this, this diff uses `getIdentifierInfo()` to find
identifiers or keywords inside Objective-C selectors.

This reverts commit r330016.
The incomplete detection has too many false positives, picking up typos
for hard failures and refusing to format anything in that case.

Summary:
This patch improves detection of incomplete code for protos and text protos.
This is especially important for text protos in raw string literals, since they
might be partial strings concatenated, and we'd like to disable formatting in
these cases.

Summary:
Previously, `clang-format` would break Objective-C
category extensions after the opening parenthesis to avoid
breaking the protocol list:
```
% echo "@interface ccccccccccccc (ccccccccccc) <ccccccccccccc> { }" | \
clang-format -assume-filename=foo.h -style="{BasedOnStyle: llvm, \
ColumnLimit: 40}"
@interface ccccccccccccc (
ccccccccccc) <ccccccccccccc> {
}
```
This looks fairly odd, as we could have kept the category extension
on the previous line.
Category extensions are a single item, so they are generally very
short compared to protocol lists. We should prefer breaking after the
opening `<` of the protocol list over breaking after the opening `(`
of the category extension.
With this diff, we now avoid breaking after the category extension's
open paren, which causes us to break after the protocol list's
open angle bracket:
```
% echo "@interface ccccccccccccc (ccccccccccc) <ccccccccccccc> { }" | \
./bin/clang-format -assume-filename=foo.h -style="{BasedOnStyle: llvm, \
ColumnLimit: 40}"
@interface ccccccccccccc (ccccccccccc) <
ccccccccccccc> {
}
```
Test Plan: New test added. Confirmed test failed before diff and
passed after diff by running:

Summary:
In D45185, I added clang-format parser support for Objective-C
generics. However, I didn't touch the whitespace logic, so they
got the same space logic as Objective-C protocol lists.
In every example in the Apple SDK and in the documentation,
there is no space between the class name and the opening `<`
for the lightweight generic specification, so this diff
removes the space and updates the tests.
Test Plan: Tests updated. Ran tests with:

Summary:
Previously, clang-format would incorrectly annotate 0-argument
Objective-C selector names as TT_TrailingAnnotation:
```
% echo "-(void)foo;" > /tmp/test.m
% ./bin/clang-format -debug /tmp/test.m
Language: Objective-C
----
Line(0, FSC=0): minus[T=68, OC=0] l_paren[T=68, OC=1] void[T=68, OC=2]
r_paren[T=68, OC=6] identifier[T=68, OC=7] semi[T=68, OC=10]
Line(0, FSC=0): eof[T=68, OC=0]
Run 0...
AnnotatedTokens(L=0):
M=0 C=0 T=ObjCMethodSpecifier S=1 B=0 BK=0 P=0 Name=minus L=1 PPK=2
FakeLParens= FakeRParens=0 Text='-'
M=0 C=1 T=Unknown S=1 B=0 BK=0 P=33 Name=l_paren L=3 PPK=2
FakeLParens= FakeRParens=0 Text='('
M=0 C=1 T=Unknown S=0 B=0 BK=0 P=140 Name=void L=7 PPK=2 FakeLParens=
FakeRParens=0 Text='void'
M=0 C=0 T=CastRParen S=0 B=0 BK=0 P=43 Name=r_paren L=8 PPK=2
FakeLParens= FakeRParens=0 Text=')'
M=0 C=1 T=TrailingAnnotation S=0 B=0 BK=0 P=120 Name=identifier L=11
PPK=2 FakeLParens= FakeRParens=0 Text='foo'
M=0 C=0 T=Unknown S=0 B=0 BK=0 P=23 Name=semi L=12 PPK=2 FakeLParens=
FakeRParens=0 Text=';'
```
This caused us to incorrectly indent 0-argument wrapped selectors
when Style.IndentWrappedFunctionNames was false, as we thought
the 0-argument ObjC selector name was actually a trailing
annotation (which is always indented).
This diff fixes the issue and adds tests.
Test Plan: New tests added. Confirmed tests failed before diff.
After diff, tests passed. Ran tests with:

Summary:
The following C++ code was being detected by
`guessLanguage()` as Objective-C:
#define FOO(...) auto bar = [] __VA_ARGS__;
This was because `[] __VA_ARGS__` is not currently detected as a C++
lambda expression (it has no parens or braces), so
`TokenAnnotator::parseSquare()` incorrectly treats the opening square
as an ObjC method expression.
We have two options to fix this:
1. Parse `[] __VA_ARGS__` explicitly as a C++ lambda
2. Make it so `[]` is never parsed as an Objective-C method expression
This diff implements option 2, which causes the `[` to be parsed
as `TT_ArraySubscriptLSquare` instead of `TT_ObjCMethodExpr`.
Note that when I fixed this, it caused one change in formatting
behavior, where the following was implicitly relying on the `[`
being parsed as `TT_ObjCMethodExpr`:
A<int * []> a;
becomes:
A<int *[]> a;
with `Style.PointerAlignment = Middle`.
I don't really know what the desired format is for this syntax; the
test was added by Janusz Sobczak and integrated by @djasper in
https://github.com/llvm-mirror/clang/commit/b511fe9818829d7ece0cc0b2ce1fbe04a1f0739a
.
I went ahead and changed the test for now.

Summary:
D44816 attempted to fix a few cases where `clang-format` incorrectly
inserted a space before the closing brace of an Objective-C dictionary
literal.
This revealed there were still a few cases where we inserted a space
after the opening brace of an Objective-C dictionary literal.
This fixes the formatting to be consistent and adds more tests.

diff and passed after diff.

Summary:
Previously, `clang-format` would sometimes insert a space
before the closing brace in an Objective-C dictionary literal.
Unlike array literals (which obey `Style.SpacesInContainerLiterals`
to add a space after `[` and before `]`), Objective-C dictionary
literals currently are not meant to insert a space after `{` and before
`}`, regardless of `Style.SpacesInContainerLiterals`.
However, some constructs like `@{foo : @(bar)}` caused `clang-format`
to insert a space between `)` and `}`.
This fixes the issue and adds tests. (I understand the behavior is
not consistent between array literals and dictionary literals, but
that's existing behavior that's a much larger change.)
Test Plan: New tests added. Ran tests with:

For multiline raw string literals, we generally want to respect the
author's choice of linebreak before the 'R"(' as the rest of the raw
string might be aligned to it and we cannot (commonly) modify the
content.
For single-line raw string literals, this doesn't make any sense and so
we should just treat them as regular string literals in this regard.

When SpacesInParentheses is set to true clang-format does not add a
space before fully qualified names. For example:
do_something(::globalVar );

Summary:
Previously, clang-format would insert a space between
the closing parenthesis and 'new' in the following valid Objective-C
declaration:
+ (instancetype)new;
This was because 'new' is treated as a keyword, not an identifier.
TokenAnnotator::spaceRequiredBefore() already handled the case where
r_paren came before an identifier, so this diff extends it to
handle r_paren before 'new'.

Summary:
Objective-C selectors with arguments take the form of:
foo:
foo:bar:
foo:bar:baz:
These can be passed to a macro, like NS_SWIFT_NAME():
https://developer.apple.com/library/content/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html
and must never have spaces inserted around the colons.
Previously, there was logic in TokenAnnotator's tok::colon parser to
handle the single-argument case, but it failed for the
multiple-argument cases.
This diff fixes the bug and adds more tests.
