Ben Hamilton df72e9851a [clang-format] Don't insert space between ObjC class and lightweight generic
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:
  % make -j16 FormatTests && ./tools/clang/unittests/Format/FormatTests

Ben Hamilton f90ad9cdac [clang-format] Ensure ObjC selectors with 0 args are annotated correctly
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:

Ben Hamilton 9dc7816346 [clang-format/ObjC] Do not detect "[]" as ObjC method expression
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
b511fe9818
.

I went ahead and changed the test for now.

Ben Hamilton d54e7aa9e2 [clang-format] Do not insert space before closing brace in ObjC dict literal
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.)

Daniel Jasper fd327674dd clang-format: Narrow down raw string literal line break exception.
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.

Ben Hamilton 5f91134344 [clang-format] Don't insert space between r_paren and 'new' in ObjC decl
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.

r_paren came before an identifier, so this diff extends it to
handle r_paren before 'new'.

These can be passed to a macro, like NS_SWIFT_NAME():

Ben Hamilton 788a2227b7 [clang-format] Improve detection of Objective-C block types
Summary:
Previously, clang-format would detect the following as an
Objective-C block type:

  FOO(^);

when it actually must be a C or C++ macro dealing with an XOR
statement or an XOR operator overload.

According to the Clang Block Language Spec:

https://clang.llvm.org/docs/BlockLanguageSpec.html

block types are of the form:

  int (^)(char, float)

and block variables of block type are of the form:

  void (^blockReturningVoidWithVoidArgument)(void);
  int (^blockReturningIntWithIntAndCharArguments)(int, char);
  void (^arrayOfTenBlocksReturningVoidWithIntArgument[10])(int);

This tightens up the detection so we don't unnecessarily detect
C macros which pass in the XOR operator.

Depends On D43904

Ben Hamilton b060ad870f [clang-format] Don't detect C++11 attribute specifiers as ObjC
Summary:
Previously, clang-format would detect C++11 and C++17 attribute
specifiers like the following as Objective-C method invocations:

  [[noreturn]];
  [[clang::fallthrough]];
  [[noreturn, deprecated("so sorry")]];
  [[using gsl: suppress("type")]];

To fix this, I ported part of the logic from
tools/clang/lib/Parse/ParseTentative.cpp into TokenAnnotator.cpp so we
can explicitly parse and identify C++11 attribute specifiers.

This allows the guessLanguage() and getStyle() APIs to correctly
guess files containing the C++11 attribute specifiers as C++,
not Objective-C.

Summary:
Previously, clang-format would detect the following as an
Objective-C for-in statement:

  for (int x = in.value(); ...) {}

because the logic only decided a for-loop was definitely *not*
an Objective-C for-in loop after it saw a semicolon or a colon.

To fix this, I delayed the decision of whether this was a for-in
statement until after we found the matching right-paren, at which
point we know if we've seen a semicolon or not.

Krasimir Georgiev 446d6ec996 [clang-format] fix handling of consecutive unary operators
Summary:
Code that used to be formatted as `if (! + object) {` is now formatted as `if (!+object) {`
(we have a particular object in our codebase where unary `operator+` is overloaded to return the underlying value, which in this case is a `bool`)

We still preserve the TypeScript behavior where `!` is a trailing non-null operator. (This is already tested by an existing unit test in `FormatTestJS.cpp`)

It doesn't appear like handling of consecutive unary operators are tested in general, so I added another test for completeness

Francois Ferrand 38d8013458 clang-format: keep ObjC colon alignment with short object name
Summary:
When the target object expression is short and the first selector name
is long, clang-format used to break the colon alignment:

  [I performSelectorOnMainThread:@selector(loadAccessories)
                       withObject:nil
                    waitUntilDone:false];

This happens because the colon is placed at `ContinuationIndent +
LongestObjCSelectorName`, so that any selector can be wrapped. This is
however not needed in case the longest selector is the firstone, and
not wrapped.

To overcome this, this patch does not include the first selector in
`LongestObjCSelectorName` computation (in TokenAnnotator), and lets
`ContinuationIndenter` decide how to account for the first selector
when wrapping. (Note this was already partly the case, see line 521
of ContinuationIndenter.cpp)

This way, the code gets properly aligned whenever possible without
breaking the continuation indent.

  [I performSelectorOnMainThread:@selector(loadAccessories)
                      withObject:nil
                   waitUntilDone:false];
  [I // force break
      performSelectorOnMainThread:@selector(loadAccessories)
                       withObject:nil
                    waitUntilDone:false];
  [I perform:@selector(loadAccessories)

(https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/ProgrammingWithObjectiveC/WorkingwithBlocks/WorkingwithBlocks.html#//apple_ref/doc/uid/TP40011210-CH8-SW7),
it should be correctly formatted nevertheless.

  #ifndef HEADER_H

This happens because we check vertical alignment against the '#' yet
indent to the level of the 'define'. This patch resolves this issue by

operators increased their precedence levels with this change), thread-safety
analysis needed changes to build its own IL properly for the new operator.

All "real" semantic checking for this operator has been deferred to a future
patch. For now, we use the relational comparison rules and arbitrarily give
the builtin form of the operator a return type of 'void'.

Martin Probst 325ff7c5e0 clang-format: [JS] wrap optional properties in type aliases.
Summary:
clang-format wraps object literal keys in an object literal if they are
marked as `TT_SelectorName`s and/or the colon is marked as
`TT_DictLiteral`. Previously, clang-format would accidentally work
because colons in type aliases were marked as `TT_DictLiteral`. r310367
fixed this to assing `TT_JsTypeColon`, which broke wrapping in certain
situations. However the root cause was that clang-format incorrectly
didn't skip questionmarks when detecting selector name.

This change fixes both locations to (1) assign `TT_SelectorName` and (2)
treat `TT_JsTypeColon` like `TT_DictLiteral`.

Previously:

    type X = {
      a: string, b?: string,
    };

Now:

    type X = {
      a: string,
      b?: string,
    };

Martin Probst 0fb46bb222 clang-format: [JS] fix union type spacing in object & array types.
Summary:
Previously, clang-format would insert whitespace in union types nested in object
and array types, as it wouldn't recognize those as a type operator:

    const x: {foo: number | null};
    const x: [number | null];

While this is correct for actual binary operators, clang-format should not
insert whitespace into union and intersection types to mark those:

    const x: {foo: number|null};
    const x: [number|null];

This change propagates that the context is not an expression by inspecting
the preceding token and marking as non-expression if it was a type colon.

  const struct A a = { .a = 1, .b = 2 };
                      ^

Also, wrapping between opening brace and designated array initializers used to have an excessive penalty (like breaking between an expression and the subscript operator), leading to unexpected wrapping:

  const struct Aaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa =
      {[1] = aaaaaaaaaaaaaaaaaaaaaaaaaaa,
       [2] = bbbbbbbbbbbbbbbbbbbbbbbbbbb};

instead of:

  const struct Aaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa = {
      [1] = aaaaaaaaaaaaaaaaaaaaaaaaaaa,
      [2] = bbbbbbbbbbbbbbbbbbbbbbbbbbb};

Finally, designated array initializers are not binpacked, just like designated member initializers.

Because the ')' is now indented at the parent level (fooObject).

Normally formatting a builder pattern style call sequence like that is
outlawed in clang-format anyway. However for JavaScript this is special
cased to support trailing .bind calls.

This change disallows this special case when following a closing ')' to
avoid the problem.

Included are some random comment fixes.

Francois Ferrand 9976efa8ff clang-format: Allow customizing the penalty for breaking assignment
Summary:
Add option to customize the penalty for breaking assignment

This allows increasing the priority of the assignment, to prefer spliting
an operation instead of splitting the assignment, e.g. :

  int a = bbbbbbbbbbbbbbbb +
          cccccccccccccccc;

Krasimir Georgiev a1c30937ce [clang-format] Handle trailing comment sections in import statement lines
Summary:
This patch updates the handling of multiline trailing comment sections in
import statement lines to make it more consistent with the case in general.
This includes updating the parsing logic to collect the trailing comment
sections and the formatting logic to not insert escaped newlines at the end of
comment lines in import statement lines.

Specifically, before this patch this code:
```
#include <a> // line 1
             // line 2
```
will be turned into two unwrapped lines, whereas this code:
```
int i; // line 1
       // line 2
```
is turned into a single unwrapped line, enabling reflowing across comments.

An example where the old behaviour is bad is when partially formatting the lines
3 to 4 of this code:
```
#include <a> // line 1
             // line 2

int i;
```
which gets turned into:
```
#include <a> // line 1
             // line 2

             int i;
```
because the two comment lines were independent and the indent was copied.

Martin Probst 2c1cdae2df JavaScript allows parameter lists to include trailing commas:
myFunction(param1, param2,);

For symmetry with other parenthesized lists ([...], {...}), clang-format should
wrap parenthesized lists one-per-line if they contain a trailing comma:

    myFunction(
        param1,
        param2,
    );

This is particularly useful in function declarations or calls with many
arguments, e.g. commonly in constructors.

Martin Probst 82b3d906bc clang-format: [JS] fix non-null assertion operator recognition.
Summary:
`getIdentifierInfo()` includes all keywords, whereas non-null assertion
operators should only be recognized after non-keywords or pseudo keywords.
Ideally this should list all tokens that clang-format recognizes as a keyword,
but that are pseudo or no keywords in JS. For the time being, just recognize
the specific bits users ran into (`namespace` in this case).

Martin Probst ad06391ca9 clang-format: [JS/Java] ignore Objective-C constructs in JS & Java.
Summary:
Java and JavaScript support annotations and decorators, respectively, that use a leading "@" token. clang-format currently detects this as an Objective-C construct and applies special formatting, for example no whitespace around "=" operators. This change disables the distinction for Java and JavaScript, which leads to normal formatting of single line annotated and initialized properties.

Before:
    class X {
      @foo() bar=false;
    }

After:
    class X {
      @foo() bar = false;
    }

Martin Probst 19c7de0a22 clang-format: [JS] prevent wraps before class members.
Summary: In JavaScript/TypeScript, class member definitions that use modifiers can be subject to Automatic Semicolon Insertion (ASI). For example, "class X { get \n foo }" defines a property called "get" and a property called "foo", both with no type annotation. This change prevents wrapping after the modifier keywords (visibility modifiers, static, get and set) to prevent accidental ASI.

Daniel Jasper c79e4d2d25 clang-format: Make it very slighly more expensive to wrap between "= {".
This prevents unwanted fallout from r296664. Specifically in proto formatting,
this changed:
  optional Aaaaaaaa aaaaaaaa = 12 [
    (aaa) = aaaa,
    (bbbbbbbbbbbbbbbbbbbbbbbbbb) = {
      aaaaaaaaaaaaaaaaa: true,
      aaaaaaaaaaaaaaaa: true
    }
  ];

Into:
  optional Aaaaaaaa aaaaaaaa = 12 [
    (aaa) = aaaa,
    (bbbbbbbbbbbbbbbbbbbbbbbbbb) =
        {aaaaaaaaaaaaaaaaa: true, aaaaaaaaaaaaaaaa: true}
  ];

Which is considered less readable. Generally, it seems preferable to
format such dict literals as blocks rather than contract them to one
line.
