Summary:
This patch makes the `{` in `msg_field{field: OK}` in a proto option scope be
treated as an assignment operator. Previosly the added test case was formatted
as:
```
option (MyProto.options) = {

Summary:
This patch adds support for <>-style proto message fields inside proto options.
Previously these were wrongly treated as binary operators and as such were
working only by chance for a limited number of cases.

Summary:
This is the same as Inline, except it does not imply all empty
functions are merged: with this style, empty functions are merged only
if they also match the 'inline' criteria (i.e. defined in a class).
This is helpful to avoid inlining functions in implementations files.

Summary:
This fixes the missing space before the designated initializer when `Cpp11BracedListStyle=false` :
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.

c++1z adds the following constructions to the language:
if constexpr (cond)
statement1;
else if constexpr (cond)
statement2;
else if constexpr (cond)
statement3;

A first version of this was proposed in reviews.llvm.org/D26953 by
Francis Visoiu Mistrih, but never commited. This patch additionally
fixes the behavior when allowing short if statements on a single line
and was authored by Jacob Bandes-Storch. Thank you to both authors.

Summary:
This option replaces the BreakConstructorInitializersBeforeComma option with an enum, thus introducing a mode where the colon stays on the same line as constructor declaration:
// When it fits on line:
Constructor() : initializer1(), initializer2() {}
// When it does not fit:
Constructor() :
initializer1(), initializer2()
{}
// When ConstructorInitializerAllOnOneLineOrOnePerLine = true:
Constructor() :
initializer1(),
initializer2()
{}

The change that enabled wrapping at the previous scope's indentation had
unintended side-effects in that clang-format would prefer to wrap
closing parentheses to the next line if it avoided a wrap on the next
line (assuming very narrow lines):
fooObject
.someCall(barbazbam)
.then(bam);
Would get formatted as:
fooObject.someCall(barbazbam
).then(bam);
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.

Add option to customize the penalty for breaking assignment
This allows increasing the priority of the assignment, to prefer spliting

llvm-svn: 303534
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.

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.

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).

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.

@foo() bar=false;

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.

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.
llvm-svn: 297696
Summary:
Previously clang-format would not break after any !. However in TypeScript, ! can be used as a post fix operator for non-nullability:
x.foo()!.bar()!;
With this change, clang-format will wrap after the ! if it is likely a post-fix non null operator.

Many things were wrong:
- We didn't always allow wrapping after "as", which can be necessary.
- We used to Undestand the identifier after "as" as a start of a name.
- We didn't properly parse the structure of the expression with "as"
having the precedence of relational operators

Summary:
Async arrow functions should be marked with a whitespace after the async keyword, before the parameter list:
x = async () => foo();
Before:
x = async() => foo();
This makes it easier to tell apart an async arrow function from a call to a function called async.

r289428 added a separate language kind for Objective-C, but kept many
"Language == LK_Cpp" checks untouched. This introduced a "IsCpp()"
method that returns true for both C++ and Objective-C++, and replaces
all comparisons of Language with LK_Cpp with calls to this new method.
Also add a lot more test coverge for formatting things in LK_ObjC mode,
by having FormatTest's verifyFormat() test for LK_ObjC everything that's
being tested for LK_Cpp at the moment.
Fixes PR32060 and many other things.

Specifically, similar to other blocks, clang-format now wraps both

This can lead to bad behavior with macros that are used to annotate
functions (e.g. ALWAYS_INLINE).
Before, this:
ALWAYS_INLINE ::std::string getName() ...
was turned into:
ALWAYS_INLINE::std::string getName() ...
If it turns out that clang-format is failing to clean up a lot of the
existing spaces now, we can add more analyses of the identifier. It
should not currently. Cases where clang-format breaks nested name
specifiers should be fine as clang-format wraps after the "::". Thus, a
line getting longer and then shorter again should lead to the same
original code.
llvm-svn: 295437
Summary:
In JavaScript, object literals can contain methods:
var x = {
a() { return 1; },
};
Previously, clang-format always parsed nested {} inside a braced list as
further braced lists. Special case this logic for JavaScript to try
parsing as a braced list, but fall back to parsing as a child block.
