Daniel Jasper 56691b8cb9 clang-format: [JS] Ensure that formatting actually takes place in tests.
And fix formatting issue discovered by that :-).

Manuel Klimek f0c95b32ec Fix crash in clang-format.
The following example used to crash clang-format.
 #define a\
  /**/}

Adjusting the indentation level cache for the line starting with the
comment would lead to an out-of-bounds array read.

Daniel Jasper 229628b39e clang-format: Don't add spaces in foreach macro definition.
Before clang-format would e.g. add a space into

   #define Q_FOREACH(x, y)

which turns this into a non-function-like macro.

Patch by Strager Neds, thank you!

Daniel Jasper 11ca263994 clang-format: [JS] Only special case top level object literal
assignments as enums.

Top level object literals are treated as enums, and their k/v pairs are put on
separate lines:

  X.Y = {
    A: 1,
    B: 2
  };

However assignments within blocks should not be affected:

  function x() {
    y = {a:1, b:2};
  }

This change fixes the second case. Patch by Martin Probst.

Daniel Jasper c83d76991c clang-format: [JS] Hotfix for runtime issue with deeply nested JS code.
I have not succeeded in writing a proper test case for this yet and we
also need to solve the underlying fundamental problem of trying too
many combinations with nested blocks (basically this somewhat works
around our Dijkstra algorithm). Preventing this linebreak is good
anyways as usually the penalties never make us choose it (that's why I
can't create a test) and it also looks ugly.

Also cleaned up state comparison code that I discovered while hunting
this down.

Daniel Jasper 6f2b88a398 clang-format: More eagerly wrap trailing return types.
Before:
  template <typename T>
  auto aaaaaaaaaaaaaaaaaaaaaa(T t) -> decltype(eaaaaaaaaaaaaaaa<T>(t.a)
                                                   .aaaaaaaa());

After:
  template <typename T>
  auto aaaaaaaaaaaaaaaaaaaaaa(T t)
      -> decltype(eaaaaaaaaaaaaaaa<T>(t.a).aaaaaaaa());

Also add a test case for a difficult template parsing case I stumbled accross.
Needs fixing.

Daniel Jasper 3b0f304517 clang-format: [JS] Let fat arrows have 'Assignment' precedence.
This is a more correct representation than using "Equality" introduced
in r238942 which was a quick fix to solve an actual regression.

According to the typescript spec, arrows behave like "low-precedence"
assignments.

Before:
  var a = a.aaaaaaa((a: a) => aaaaaaaaaaaaaaaaaaaaa(bbbbbbbbb) &&
                    aaaaaaaaaaaaaaaaaaaaa(bbbbbbb));
After:
  var a = a.aaaaaaa((a: a) => aaaaaaaaaaaaaaaaaaaaa(bbbbbbbbb) &&
                              aaaaaaaaaaaaaaaaaaaaa(bbbbbbb));

Daniel Jasper 3c306e895e clang-format: [JS] Let fat arrows have 'Equality' precedence.
This fixes a regression in literal formatting:

Before:
  aaaaaaaaaaaaa = {
    aaaaaaaaaaaaaaaaaaaaaaaaaaaa: (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
                                   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa) =>
        aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
  };

After:
  var aaaaaaaaaaaaaaaaaaaa = {
    aaaaaaaaaaaaaaaaaaaaaaaaaaaa:
        (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
         aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa) =>
                aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
  };

Also apply no-else-after-return policy.

Daniel Jasper 1699eca119 clang-format: [JS] Making arrow function wrapping more consistent.
Before:
  someFunction(() =>
               {
                 doSomething();  // break
               })

After:
  someFunction(() => {
    doSomething();  // break
  })
      .doSomethingElse(  // break
          );

This is still bad, but at least it is consistent with what we do for other
function literals. Added corresponding tests.

Manuel Klimek 3d3ea84a4f Refactor clang-format's formatter.
Summary:
a) Pull out a class LevelIndentTracker whose responsibility is to keep track
   of the indent of levels across multiple annotated lines.
b) Put all responsibility for merging lines into the LineJoiner; make the
   LineJoiner iterate over the lines so we never operate on a line that might
   be merged later; this makes the interface safer to use.
c) Move formatting of the end-of-file whitespace into formatFirstToken.

Fix bugs that became obvious after the refactoring:
1. We would not format lines with offsets correctly inside nested blocks if
   only the outer expression was affected:
   int x = s({ // clang-format only this line
     class X {
       public:
    // ^ this starts at the non-modified indnent level; previously we would
    //   not fix this, now we correctly outdent it.
       void f();
     };
   });
2. We would incorrectly align comments across lines that do not have comments
   for lines with nested blocks:
   int expression; // with comment
   int x = s({
     int y; // comment
     int z; // we would incorrectly align this comment with the comment on
            // 'expression'
   });

In particular:
* If the difference between the longest and shortest element, we copped
  out of column format completely. Now, we instead allow to arrange
  these in a single column, essentially enforcing a one-per-line format.
* Allow column layout even if there are braced lists. Especially, if
  there are many short lists, this can be beneficial. The bad case,
  where there is a long nested init list is usually caught as we now
  limit the length difference of the longest and shortest element.

Optional methods use ? tokens like this:

The option will change code such as:

Daniel Jasper 60948b12bb clang-format: [JS] more precisely detect enums.
The current enum detection is overly aggressive. As NestingLevel only
applies per line (?) it classifies many if not most object literals as
enum declarations and adds superfluous line breaks into them. This
change narrows the heuristic by requiring an assignment just before the
open brace and requiring the line to start with an identifier.

Daniel Jasper 98f8ae34da clang-format: Slightly change indentation rules in for loops.
There was already a TODO to double-check whether the extra indenation
makes sense. A slightly different case reveals that it is actively harmful:

  for (int i = 0; i < aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ||
                      bbbbbbbbbbbbbbbbbbbb < ccccccccccccccc;
       ++i) {
  }

Here (and it is probably not a totally infrequent case, it just works out that
"i < " is four spaces and so the four space extra indentation makes the
operator precedence confusing. So, this will now instead be formatted
as:

  for (int i = 0; i < aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ||
                  bbbbbbbbbbbbbbbbbbbb < ccccccccccccccc;
       ++i) {

This is consistent with how we format C++ try blocks and SEH try blocks.
clang-format not doing this before was an implementation oversight.

This is dependent on BraceBreakingStyle.  The snippet above is with the
Attach style.  Style Stroustrip for example still results in the "Before:"
snippet, which makes sense since other blocks (try, else) break after '}' too.

correctly. __try and __finally are keywords if `LangOpts.MicrosoftExt` is set,
so this turns this on.  This also enables a few other keywords, but it
shouldn't overly perturb regular clang-format operation.  __except is a
context-sensitive keyword, so `AdditionalKeywords` needs to be passed around to
a few more places.

r225141 changed the defaults of AllowShortIfStatementsOnASingleLine and
AlignTrailingComments for Google style and added explicit overrides for
Chromium style to undo these changes.  For AllowShortIfStatementsOnASingleLine
that's good as the Android style guide (which Chromium uses for Java) explicitly
permits single-line ifs. But it's silent on trailing comments, to it makes
sense for Chromium style to just follow Google style.

Roman Kashitsyn 650ecb53ca Fix bug 20892 - clang-format does not handle C-style comments
Summary:
http://llvm.org/bugs/show_bug.cgi?id=20892

Add support of C-style formatting enabling/disabling directives. Now the following two styles are supported:

  // clang-format on
  /* clang-format on */

The flexibility in comments (support of extra spaces and/or slashes, etc.) is deliberately avoided to simplify search in large code bases.

On a single line:

Not on a single line:

Daniel Jasper 23376259c0 clang-format: [JS] Support regex literals with trailing escaped slash.
Before:
  var regex = / a\//; int i;

After:
  var regex = /a\//;
  int i;

This required pushing the Lexer into its wrapper class and generating a
new one in this specific case. Otherwise, the sequence get lexed as a
//-comment. This is hacky, but I don't know a better way (short of
supporting regex literals in the Lexer).

Pushing the Lexer down seems to make all the call sites simpler.
