These statements are like switch statements in C, but without the 'case'
keyword in labels.
How labels are parsed. In UnwrappedLineParser, the program tries to
parse a statement every time it sees a colon. In TokenAnnotator, a
colon that isn't part of an expression is annotated as a label.
The token type `TT_GotoLabelColon` is added. We did not include Verilog
in the name because we thought we would eventually have to fix the
problem that case labels in C can't contain ternary conditional
expressions and we would use that token type.
The style is like below. Labels are on separate lines and indented by
default. The linked style guide also has examples where labels and the
corresponding statements are on the same lines. They are not supported
for now.

This style is similar to AlwaysBreak, but places closing brackets on new lines.
For example, if you have a multiline parameter list, clang-format currently only supports breaking per-parameter, but places the closing bracket on the line of the last parameter.
Function(
param1,
param2,
param3);
A style supported by other code styling tools (e.g. rustfmt) is to allow the closing brackets to be placed on their own line, aiding the user in being able to quickly infer the bounds of the block of code.
Function(
param1,
param2,
param3
);
For prior work on a similar feature, see: https://reviews.llvm.org/D33029.
Note: This currently only supports block indentation for closing parentheses.

Make sure we do not try to change line comments that are non-regular, i.e. do
not start with "//" or "#". This can for example happen when "//" is
broken into two lines with an escaped newline.
1. IndexTokenSource::getNextToken cannot return nullptr; some code was
still written assuming it can; make getNextToken more resilient against
incorrect input and fix its call-sites.
2. Change various asserts that can happen due to user provided input to
conditionals in the code.
Add a new option PackConstructorInitializers and deprecate the
related options ConstructorInitializerAllOnOneLineOrOnePerLine and
AllowAllConstructorInitializersOnNextLine. Below is the mapping:
PackConstructorInitializers ConstructorInitializer... AllowAll...
Never - -
BinPack false -
CurrentLine true false
NextLine true true
The option value Never fixes PR50549 by always placing each
constructor initializer on its own line.

The patch https://reviews.llvm.org/D105964 (58494c856a)
updated detection of function declaration names. It had the unfortunate
consequence that it started breaking between `function` and the function
name in some cases in JavaScript code.
This patch addresses this.

I find as I develop I'm moving between many different languages C++,C#,JavaScript all the time. As I move between the file types I like to keep `clang-format` as my formatting tool of choice. (hence why I initially added C# support in {D58404}) I know those other languages have their own tools but I have to learn them all, and I have to work out how to configure them, and they may or may not have integration into my IDE or my source code integration.
I am increasingly finding that I'm editing additional JSON files as part of my daily work and my editor and git commit hooks are just not setup to go and run [[ https://stedolan.github.io/jq/ | jq ]], So I tend to go to [[ https://jsonformatter.curiousconcept.com/ | JSON Formatter ]] and copy and paste back and forth. To get nicely formatted JSON. This is a painful process and I'd like a new one that causes me much less friction.
This has come up from time to time:

https://stackoverflow.com/questions/35856565/clang-format-a-json-filehttps://bugs.llvm.org/show_bug.cgi?id=18699
I would like to stop having to do that and have formatting JSON as a first class clang-format support `Language` (even if it has minimal style settings at present).
This revision adds support for formatting JSON using the inbuilt JSON serialization library of LLVM, With limited control at present only over the indentation level
This adds an additional Language into the .clang-format file to separate the settings from your other supported languages.

This updates the canonical text proto raw string delimiter to `pb` for Google style, moving codebases towards a simpler and more consistent style.
Also updates a behavior where the canonical delimiter was not applied for raw strings with empty delimiters detected via well-known enclosing functions that expect a text proto, effectively making the canonical delimiter more viral. This feature is not widely used so this should be safe and more in line with promoting the canonicity of the canonical delimiter.

A quick search of github.com, shows one common scenario for excessive use of //clang-format off/on is the indentation of #pragma's, especially around the areas of loop optimization or OpenMP
This revision aims to help that by introducing an `IndentPragmas` style, the aim of which is to keep the pragma at the current level of scope
```
for (int i = 0; i < 5; i++) {
// clang-format off
#pragma HLS UNROLL
// clang-format on
for (int j = 0; j < 5; j++) {
// clang-format off
#pragma HLS UNROLL
// clang-format on
....
```
can become
```
for (int i = 0; i < 5; i++) {
#pragma HLS UNROLL
for (int j = 0; j < 5; j++) {
#pragma HLS UNROLL
....
```
This revision also support working alongside the `IndentPPDirective` of `BeforeHash` and `AfterHash` (see unit tests for examples)

Summary:
After D50078, we're experiencing unexpected un-indent using a style combining `AlignOperands: DontAlign` with `BreakBeforeTernaryOperators: false`, such as Google's JavaScript style:
```
% bin/clang-format -style=google ~/test.js
aaaaaaaaaaa = bbbbbbbb ? cccccccccccccccccc() :
dddddddddd ? eeeeeeeeeeeeee :
fffff;
```
The issue lies with the interaction of `AlignOperands: DontAlign` and the edited code section in ContinuationIndenter.cpp, which de-dents the intent by `Style.ContinuationIndentWidth`. From [[ ac3e5c4d93/clang/include/clang/Format/Format.h (L170) | the documentation ]] of AlignOperands: DontAlign:
> The wrapped lines are indented `ContinuationIndentWidth` spaces from the start of the line.
So the de-dent effectively erases the necessary `ContinuationIndentWidth` in that case.
This patch restores the `AlignOperands: DontAlign` behavior, producing:
```
% bin/clang-format -style=google ~/test.js
aaaaaaaaaaa = bbbbbbbb ? cccccccccccccccccc() :
dddddddddd ? eeeeeeeeeeeeee :
fffff;
```

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, the operands are actually aligned, and the operator
gets aligned with the equal sign:
int aaaaa = bbbbbb
+ cccccc;
This not happen in tests, to avoid 'breaking' the indentation:
if (aaaaa
&& bbbbb)
return;

Summary:
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;
