Summary:
Even when BreakBeforeBinaryOperators is set, AlignOperands kept
aligning the beginning of the line, even when it could align the
actual operands (e.g. after an assignment).
With this patch, there is an option to actually align the operands, so
that the operator gets right-aligned with the equal sign or return
operator:
int aaaaa = bbbbbb
+ cccccc;
return aaaaaaa
&& bbbbbbb;
This not happen in parentheses, to avoid 'breaking' the indentation:
if (aaaaa
&& bbbbb)
return;

When multiple ternary operators are chained, e.g. like an if/else-if/
else-if/.../else sequence, clang-format will keep aligning the colon
with the question mark, which increases the indent for each
conditionals:
int a = condition1 ? result1
: condition2 ? result2
: condition3 ? result3
: result4;
This patch detects the situation (e.g. conditionals used in false branch
of another conditional), to avoid indenting in that case:
int a = condition1 ? result1
: condition2 ? result2
: condition3 ? result3
: result4;
When BreakBeforeTernaryOperators is false, this will format like this:
int a = condition1 ? result1 :
condition2 ? result2 :
conditino3 ? result3 :
result4;
Summary:
Use spaces instead of tabs for alignment with UT_ForContinuationAndIndentation to make the code aligned for any tab/indent width.

Summary:
clang-format currently puts the first enumerator on the same line as the
enum keyword and opening brace if it fits (for example, for anonymous
enums if IndentWidth is 8):
$ echo "enum { RED, GREEN, BLUE };" | clang-format -style="{BasedOnStyle: llvm, ColumnLimit: 15, IndentWidth: 8}"
enum { RED,
GREEN,
BLUE };
This doesn't seem to be intentional, as I can't find any style guide that
suggests wrapping enums this way. Always force the enumerator to be on a new
line, which gets us the desired result:
$ echo "enum { RED, GREEN, BLUE };" | ./bin/clang-format -style="{BasedOnStyle: llvm, ColumnLimit: 15, IndentWidth: 8}"
enum {
RED,
GREEN,
BLUE
};

Summary:
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.

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.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Summary:
This is a fix for https://bugs.llvm.org/show_bug.cgi?id=43333
This comes with 3 main parts
- C# attributes cause function names on a new line even when AlwaysBreakAfterReturnType is set to None
- Add AlwaysBreakAfterReturnType to None by default in the Microsoft style,
- C# unit tests are not using Microsoft style (which we created to define the default C# style to match a vanilla C# project).

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.

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");
```

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.

We understand that people may be surprised that we're moving the header

Essentially, all code in the project is now made available by the LLVM

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);

Summary:
Currently clang-format breaks before the next parameter after multiline parameters (also recursively for the parent expressions of multiline parameters). However, it fails to do so for formatted multiline raw string literals:
```
$ cat test.cc
// Examples
// Regular multiline tokens
int x = f(R"(multi
line)", 2);
}
int y = g(h(R"(multi
line)"), 2);
// Formatted multiline tokens
int z = f(R"pb(multi: 1 #
line: 2)pb", 2);
int w = g(h(R"pb(multi: 1 #
line: 2)pb"), 2);
$ clang-format -style=google test.cc
// Examples
// Regular multiline tokens
int x = f(R"(multi
line)",
2);
}
int y = g(h(R"(multi
line)"),
2);
// Formatted multiline tokens
int z = f(R"pb(multi: 1 #
line: 2)pb", 2);
int w = g(h(R"pb(multi: 1 #
line: 2)pb"), 2);
```
This patch addresses this inconsistency by forcing breaking after multiline formatted raw string literals. This requires a little tweak to the indentation chosen for the contents of a formatted raw string literal: in case when that's a parameter and not the last one, the indentation is based off of the uniform indentation of all of the parameters.
