Krasimir Georgiev 17725d8391 [clang-format] Enable comment reflowing in multiline comments containing pragmas
Summary:
This patch enables comment reflowing of lines not matching the comment pragma regex
in multiline comments containing comment pragma lines. Previously, these comments
were dumped without being reindented to the result.

Krasimir Georgiev 9163fe2aba [clang-format] Use number of unwrapped lines for short namespace
Summary:
This patch makes the namespace comment fixer use the number of unwrapped lines
that a namespace spans to detect it that namespace is short, thus not needing
end comments to be added.
This is needed to ensure clang-format is idempotent. Previously, a short namespace
was detected by the original source code lines. This has the effect of requiring two
runs for this example:
```
namespace { class A; }
```
after first run:
```
namespace {
class A;
}
```
after second run:
```
namespace {
class A;
} // namespace
```

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.

Daniel Jasper 23c2b5ae7e clang-format: Don't remove existing spaces between identifier and ::.
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.

Summary:
Comment reflower was adding untouchable tokens in case two consecutive comment lines are aligned in the source code. This disallows the whitespace manager to re-indent them later.

int i = f(abc, // line 1

Daniel Jasper 21f7dea5f5 clang-format: Don't force-wrap multiline RHSs for 2-operand experssions.
This rows back on r288120, r291801 and r292110. I apologize in advance
for the churn. All of those revisions where meant to make the wrapping
of RHS expressions more consistent. However, now that they are
consistent, we seem to be a bit too eager.

The reasoning here is that I think it is generally correct that we want
to line-wrap before multiline RHS expressions (or multiline arguments to
a function call). However, if there are only two of such operands or
arguments, there is always a clear vertical separation between them and
the additional line break seems much less desirable.

Somewhat good examples are expressions like:

  EXPECT_EQ(2, someLongExpression(
                   orCall));

Krasimir Georgiev 8432161f1d [clang-format] Separate line comment sections after a right brace from comment sections in the scope.
Summary:
The following two comment lines form a single comment section:
```

This is because the break of a comment section was based on the original column
of the first token of the previous line (in this case, the 'if').
This patch splits these two comment lines into different sections by taking into
account the original column of the right brace preceding the first line comment
where applicable.

Summary: Change r291428 introduced ASI detection after closing curly braces. That would generally be correct, however this breaks indentation for structural statements. What happens is that CompoundStatementIndenter increases indentation for the current line, then after reading ASI creates a new line (with the increased line level), and only after the structural parser sees e.g. the if/then/else branch closed, line level is reduced. That leads to the new line started by ASI having a level too high.

Single-column layout basically means that we format the list with one

the column limit.

Actual regression was introduced in r272668. This revision fixes JS script, but
also regress Cpp case. It manifests with spaces added when template is followed
with array. Bug 30527 mentions case of array as a nested template type
(foo<bar<baz>[]>). Fix is to detect such case and to prevent treating it as
array initialization, but as a subscript case. However, before r272668, this
case was treated simple because we were detecting it as a StartsObjCMethodExpr.
Same was true for other similar case - array of templates (foo<int>[]). This
patch tries to address two problems: 1) fixing regression 2) making sure both
cases (array as a nested type, array of templates) which were entering
StartsObjCMethodExpr branch are handled now appropriately.

Daniel Jasper fda47cd873 Skip over AnnotatedLines with >50 levels of nesting; don't format them.
Reasoning:
- ExpressionParser uses a lot of stack for these, bad in some environments.
- Our formatting algorithm is N^3 and gets really slow.
- The resulting formatting is unlikely to be any good.
- This is probably generated code we're formatting by accident.

We treat these as unparseable, and signal incomplete formatting. 50 is
an arbitrary number, I've only seen real problems from ~150 levels.

Daniel Jasper 496c199959 clang-format: [JavaScript] Do requoting in a separate pass
The attempt to fix requoting behavior in r280487 after changes to
tooling::Replacements are incomplete. We essentially need to add to
replacements at the same position, one to insert a line break and one to
change the quoting and that's incompatible with the new
tooling::Replacement API, which does not allow for order-dependent
Replacements. To make the order clear, Replacements::merge() has to be
used, but that requires the merged Replacement to actually refer to the
changed text, which is hard to reproduce for the requoting.

This change fixes the behavior by moving the requoting to a completely
separate pass. The added benefit is that no weird ColumnWidth
calculations are necessary anymore and this should just work even if we
implement string literal splitting in the future.

Martin Probst 6f43efbdde clang-format: [JS] fix an assertion failure caused by shrinking sources.
Summary:
The JavaScript import sorter has a corner condition that can cause the overall
source text length to shrink. This change circumvents the issue by appending
trailing space in the line after the import blocks to match at least the
previous source code length.

This needs a better long term fix, but this fixes the immediate issue.

Daniel Jasper 50780ce110 clang-format: [ObjC+JS] Allow bin-packing of array literals.
After reading the style guides again, they don't actually say how to
pack or not pack array literals. Based on some user reports, array
initializers can unnecessarily get quite long if they contain many
small elements. Array literals with trailing commas are still formatted
one per line so that users have a way to opt out of the packing.

Before:
  var array = [
    aaaaaa,
    aaaaaa,
    aaaaaa,
    aaaaaa,

Benjamin Kramer dab50463d0 [clang-format] Fix comment aligning when there are changes within the comment
As soon as a comment had whitespace changes inside of the token, we
couldn't identify the whole comment as a trailing comment anymore and
alignment stopped working. Add a new boolean to Change for this special
case and fix trailing comment identification to use it.

This also changes WhitespaceManager to sum the length of all Changes
inside of a token into the first Change.

Before this fix

  int xy;  // a
  int z;   //b

became

  int xy;  // a
  int z;  // b

with this patch we immediately get to:

Daniel Jasper 06ca0fc69d clang-format: Slightly row back on r257257.
r257257 change the way clang-format enforces line breaks after a
templated type has been line-wrapped. This was to fix an incorrect line
break if BinPackParameters is set to false. However, it also leads to
an unwanted line break in a different case. Thus, for now, only do this
when BinPackParameters is false. This isn't ideal yet, but helps us
until we have a better solution.

some corner cases in C++, where this kind of formatting is really bad.

Example:
Before:
  virtual aaaaaaaaaaaaaaaa(std::function<bool()> IsKindWeWant = [&]() {
    return true;
  }, aaaaa aaaaaaaaa);

After:
  virtual aaaaaaaaaaaaaaaa(std::function<bool()> IsKindWeWant =
                               [&]() { return true; },
                           aaaaa aaaaaaaaa);

The block formatting logic in JavaScript will probably go some other changes,
too, and we'll potentially be able to make the rules more consistent again. For
now, this seems to be the best approach for C++.

Roman Kashitsyn 291f64fd03 Add WebKit brace style configuration option.
Summary:
Add brace style `BS_WebKit` as described on https://www.webkit.org/coding/coding-style.html:

* Function definitions: place each brace on its own line.
* Other braces: place the open brace on the line preceding the code block; place the close brace on its own line.

Set brace style used in `getWebKitStyle()` to the newly added `BS_WebKit`.

Manuel Klimek 9e32199861 Do not force linebreaks when MaxEmptyLinesToKeep is 0.
Previously we would format
 call(

     p);
as
 call(
     p);
with MaxEmptyLinesToKeep == 0.

Now we format it as:
  call(p);

Daniel Jasper c6dd273a98 clang-format: [Proto] Handle enum bodies differently.
In proto, enum constants can contain complex options and should be
handled more like individual declarations.
