Paul Hoad 88335c21a4 [clang-format] [PR41187] moves Java import statements to the wrong location if code contains statements that start with the word import
Summary:
Import sorting of java file, incorrectly move import statement to after a function beginning with the word import.

Make 1 character change to regular expression to ensure there is always at least one space/tab after the word import

Previously clang-format --style="LLVM" would format

```
import X;

class C {
  void m() {
    importFile();
  }
}
```
as

```
class C {
  void m() {
    importFile();
import X;
  }
}
```

Reuben Thomas 08a940d629 [clang-format]: Add NonEmptyParentheses spacing option
This patch aims to add support for the following rules from the JUCE coding standards:

- Always put a space before an open parenthesis that contains text - e.g. foo (123);
- Never put a space before an empty pair of open/close parenthesis - e.g. foo();

Krasimir Georgiev fc67176eec [clang-format] Refine structured binding detection
Summary:
Revision r356575 had the unfortunate consequence that now clang-format never
detects an ObjC call expression after `&&`.

This patch tries harder to distinguish between C++17 structured bindings and
ObjC call expressions and adds a few regression tests.

Paul Hoad cbb726d0c5 [clang-format] Add basic support for formatting C# files
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.

Martin Probst 26a484f479 [clang-format] [JS] handle private members.
Addresses PR40999 https://bugs.llvm.org/show_bug.cgi?id=40999

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.

Martin Probst b274d3d799 [clang-format] [JS] Don't break between template string and tag
Before:
    const x = veryLongIdentifier
        `hello`;
After:
    const x =
        veryLongIdentifier`hello`;

While it's allowed to have the template string and tag identifier
separated by a line break, currently the clang-format output is not
stable when a break is forced. Additionally, disallowing a line break
makes it clear that the identifier is actually a tag for a template
string.

This patch adds a bit of logic to handle these cases and documents them in
tests.

The commented-out test cases in the new test suite are ones that were
problematic before r355434.

[1] in llvm `.td` files, the regex `\[[^ ]` (bracket followed by not-a-space) shows up ~400 times, but `\[\s[^ ]` (bracket followed by one space and one not-a-space) shows up ~40 times => ~90% uses this format.

The trailing comments of this code block should be aligned, but aren't

To align the first trailing comment it needs to insert 8 spaces. This should be
one tab plus six spaces. It skips the logic of the first partial tab in

Ben Hamilton 30b7d09d7a [Format/ObjC] Fix [foo bar]->baz formatting as lambda arrow
Summary:
Currently, `UnwrappedLineParser` thinks an arrow token after
an ObjC method expression is a C++ lambda arrow, so it formats:

```
[foo bar]->baz
```

as:

```
[foo bar] -> baz
```

Because `UnwrappedLineParser` runs before `TokenAnnotator`, it can't
know if the arrow token is after an ObjC method expression or not.

This diff makes `TokenAnnotator` remove the TT_LambdaArrow on
the arrow token if it follows an ObjC method expression.

Test Plan: New test added. Ran test with:
  % ninja FormatTests && ./tools/clang/unittests/Format/FormatTests
  Confirmed test failed before diff and passed after diff.

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

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

ObjCExpr. However that's not enough, as we might have a comma-separated list of
such clobbers as in the newly added test.
This updates the detection to instead look at the Line's first token being `asm`
and not mark `[`-s as ObjCExprs in this case.

Jordan Rupprecht 054dc28afa [clang-format] Support breaking consecutive string literals for TableGen
Summary:
clang-format can get confused by string literals in TableGen: it knows that strings can be broken up, but doesn't seem to understand how that can be indented across line breaks, and arranges them in a weird triangular pattern. Take this output example from `clang-format tools/llvm-objcopy/ObjcopyOpts.td` (which has now been formatted in rL345896 with this patch applied):

```
defm keep_global_symbols
: Eq<
      "keep-global-symbols", "Reads a list of symbols from <filename> and "
                             "runs as if " "--keep-global-symbol=<symbol> "
                                           "is set for each one. "
                                           "<filename> " "contains one "

Summary:
The issue is that for array subscript like:

```
ClangFormat will recognize it as C++11 attribute syntax and put a space between 'arr' and first '[', like:

Now it is fixed. Tested with:

Krasimir Georgiev 5528cace04 [clang-format] tweaked another case of lambda formatting
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);

Refer to the new tests in FormatTest.cpp

Krasimir Georgiev 128fcffb06 [clang-format] Break before next parameter after a formatted multiline raw string parameter
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.

Hans Wennborg 749c1b597a Java annotation declaration being handled correctly
Previously, Java annotation declarations (@interface AnnotationName) were being
handled as ObjC interfaces. This caused the brace formatting to mess up, so
that when you had a class with an interface defined in it, it would indent the
final brace of the class.

It used to format this class like so:

  class A {
    @interface B {}
    }

But will now just skip the @interface and format it like so:

  class A {
    @interface B {}
  }

This patch moves the virtual file system form clang to llvm so it can be
used by more projects.

Concretely the patch:
 - Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
 - Moves the corresponding unit test from clang to llvm.
 - Moves the vfs namespace from clang::vfs to llvm::vfs.
 - Formats the lines affected by this change, mostly this is the result of
   the added llvm namespace.

The existing code kept the space if it was there for identifiers, and it didn't
handle `this`. After this patch, for Java `this` is handled in addition to
identifiers, and existing space is always stripped between identifier and `::`.

Also accept `::` in addition to `.` in front of `<` in `foo::<T>bar` generic
calls.

Francois Ferrand 6f40e21a16 clang-format: better handle statement macros
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.
