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.

Martin Probst 8e3eba0373 clang-format: [JS] correcly format object literal methods.
Summary:
In JavaScript, object literals can contain methods:

   var x = {
     a() { return 1; },
   };

Previously, clang-format always parsed nested {} inside a braced list as
further braced lists. Special case this logic for JavaScript to try
parsing as a braced list, but fall back to parsing as a child block.

Summary:
Regex detection would incorrectly classify a trailing `!` operator
(nullability cast) followed by a `/` as the start of a regular
expression literal. This fixes code such as:

    var foo = x()! / 10;

Which would previously parse a regexp all the way to the end of the

Krasimir Georgiev 13dbaa09e5 [clang-format] Fix regression about not aligning trailing comments in case they were previously aligned, but at different indent.
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.

source:
```
int i = f(abc, // line 1
          d, // line 2
	     // line 3
	  b);
```
Since line 2 and line 3 are aligned, the reflower was marking line 3 as untouchable; however the three comment lines need to be re-aligned.
output before:
```
int i = f(abc, // line 1
          d,   // line 2
	     // line 3

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));

Daniel Jasper 7d42f3f746 [clang-format] Refactor WhitespaceManager and friends
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.

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.

Martin Probst d40bca431d clang-format: [JS] ASI after imports
Summary:
Automatic semicolon insertion should break import and export statements:

Before, this would format on one line:

  // Note: no semi after 'x' below!
  import {x} from 'x'
  export function foo() {}

Into:
  import {x} from 'x' export function foo() {}

With this change, the statements get separated.

This also improves automatic semicolon insertion to consider closing
braces preceding declarations and statements.

Summary:

The problem was that clang-format would unconditionally try to parse a child block, even though ambient function declarations do not have a body (similar to forward declarations).

While for <<-operators often used in log statments, a single key value

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

doesn't change the fact that there is an item that doesn't fit within
the column limit.

Before (with a column limit of 30):
  std::vector<int> a = {
      aaaaaaaa, aaaaaaaa,
      aaaaaaaa, aaaaaaaa,

While C(++) and ObjC are generally formatted the same way and can be

implements a very crude detection of whether or not a .h file contains

Nico Weber b2673a1e48 [clang-format] Fix PR30527: Regression when clang-format insert spaces in [] when in template
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.

- 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.

Justin Lebar 9091055efa Move UTF functions into namespace llvm.
Summary:
This lets people link against LLVM and their own version of the UTF
library.

I determined this only affects llvm, clang, lld, and lldb by running

$ git grep -wl 'UTF[0-9]\+\|\bConvertUTF\bisLegalUTF\|getNumBytesFor' | cut -f 1 -d '/' | sort | uniq
  clang
  lld
  lldb
  llvm

Tested with

  ninja lldb
  ninja check-clang check-llvm check-lld

(ninja check-lldb doesn't complete for me with or without this patch.)

Daniel Jasper e31388aee9 [clang-format] Don't allow newline after uppercase Obj-C block return types
Fixes the following:
  BOOL (^aaa)(void) = ^BOOL {
  };

The first BOOL's token was getting set to TT_FunctionAnnotationRParen
incorrectly, which was causing an unexpected newline after (^aaa). This
was introduced in r245846.

  that is an #include directive, this will insert the #include into the

- If a replacement has offset UINT_MAX, length 1, and a replacement text
  that is the name of the header to be removed, the header will be removed
  from \p Code if it exists.

Summary:
Before when a semicolon was missing after a boolean literal:

    return 1;

clang-format would parse this as one line and format as:
    a = true return 1;

It turns out that C++ does not consider `true` and `false` to be literals, we
have to check for that explicitly.

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.

JavaScript template strings can be nested arbitrarily:

This change lexes nested template strings using a stack of lexer states to

Also, reuse the same stack for the token-stashed logic.
