Summary:
Other macros are used to declare namespaces, and should thus be handled
similarly. This is the case for crpcut's TESTSUITE macro, or for
unittest-cpp's SUITE macro:
TESTSUITE(Foo) {
TEST(MyFirstTest) {
assert(0);
}
} // TESTSUITE(Foo)
This patch deals with this cases by introducing a new option to specify
lists of namespace macros. Internally, it re-uses the system already in
place for foreach and statement macros, to ensure there is no impact on
performance.

Summary:
Adds a `TypenameMacros` configuration option that causes certain identifiers to be handled in a way similar to `typeof()`.
This is enough to:
- Prevent misinterpreting declarations of pointers to such types as expressions (`STACK_OF(int) * foo` -> `STACK_OF(int) *foo`),
- Avoid surprising line breaks in variable/struct field declarations (`STACK_OF(int)\nfoo;` -> `STACK_OF(int) foo;`, see https://bugs.llvm.org/show_bug.cgi?id=30353).

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.

Private fields and methods in JavaScript would get incorrectly indented
(it sees them as preprocessor directives and hence left aligns them)
In this revision `#identifier` tokens `tok::hash->tok::identifier` are
merged into a single new token `tok::identifier` with the `#` contained
inside the TokenText.
Before:
```
class Example {
pub = 1;
static pub2 = "foo";
static #priv2 = "bar";
method() { this.#priv = 5; }
static staticMethod() {
switch (this.#priv) {
case '1':
break;
}
}
this.#privateMethod(); // infinite loop
}
static #staticPrivateMethod() {}
}
```
After this fix the code will be correctly indented
```
class Example {
pub = 1;
#priv = 2;
static pub2 = "foo";
static #priv2 = "bar";
method() { this.#priv = 5; }
static staticMethod() {
switch (this.#priv) {
case '1':
#priv = 3;
break;
}
}
#privateMethod() {
this.#privateMethod(); // infinite loop
}
static #staticPrivateMethod() {}
}
```
NOTE: There might be some JavaScript code out there which uses the C
processor to preprocess .js files
http://www.nongnu.org/espresso/js-cpp.html. It's not clear how this
revision or even private fields and methods would interact.

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:
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:
Some macros are used in the body of function, and actually contain the trailing semicolon: they should thus be automatically followed by a new line, and not get merged with the next line. This is for example the case with Qt's Q_UNUSED macro:
void foo(int a, int b) {
Q_UNUSED(a)
return b;
}
This patch deals with these cases by introducing a new option to specify list of statement macros. This re-uses the system already in place for foreach macros, to ensure there is no impact on performance.

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.

This fixes formatting namespaces with preceding 'inline' and 'export' (Modules TS) specifiers.
This change fixes namespaces not being identified as such with preceding 'inline' or 'export' specifiers.
Motivation: I was experimenting with the Modules TS (-fmodules-ts) and found it would be useful if clang-format would correctly format 'export namespace'. While making the changes, I noticed that similar issues still exist with 'inline namespace', and addressed them as well.

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.

Having inline block as a first argument when method has multiple parameters is
discouraged by Apple:
"It’s best practice to use only one block argument to a method. If the
method also needs other non-block arguments, the block should come last"
(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.

a = 42;

Correctly determine when [ is part of a structured binding instead of a
lambda.
To be able to reuse the implementation already available, this patch also:
- sets the Previous link of FormatTokens in the UnwrappedLineParser
- moves the isCppStructuredBinding function into FormatToken
Before:
auto const const &&[x, y] { A *i };
After:
auto const const && [x, y]{A * i};
Fixing formatting of the type of the structured binding is still missing.
llvm-svn: 313742
Summary:
This patch introduces a few extra BraceWrapping options, similar to
`SplitEmptyFunction`, to allow merging empty 'record' bodies (e.g.
class, struct, union and namespace):
* SplitEmptyClass
* SplitEmptyStruct
* SplitEmptyUnion
* SplitEmptyNamespace
The `SplitEmptyFunction` option name has also been simplified/
shortened (from `SplitEmptyFunctionBody`).
These options are helpful when the correspond AfterXXX option is
enabled, to allow merging the empty record:
class Foo
{};
In addition, this fixes an unexpected merging of short records, when
the AfterXXXX options are used, which caused to be formatted like
this:
class Foo
{ void Foo(); };
This is now properly formatted as:
class Foo
{
void Foo();
};

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.

The main motivation behind this is to cleanup the WhitespaceManager and
make it more extensible for future alignment etc. features.
Specifically, WhitespaceManager has started to copy more and more code
that is already present in FormatToken. Instead, I think it makes more
sense to actually store a reference to each FormatToken for each change.
This has as a consequence led to a change in the calculation of indent
levels. Now, we actually compute them for each Token ahead of time,
which should be more efficient as it removes an unsigned value for the
ParenState, which is used during the combinatorial exploration of the
solution space.
No functional changes intended.
