clang-format already prevented sequences like:
...
SomeParameter).someFunction(
...
as those are quite confusing. This failed on:
...
SomeParameter).someFunction(otherFunction(
...
Fixed in this patch.

Summary:
Do this to avoid spoling nicely formatted multi-line comments (e.g.
with code examples or similar stuff).

This yields a log(#ast_nodes) worst-case improvement with matchers like
stmt(unless(hasAncestor(...))).
Also made the order of visitation for ancestor matches BFS, as the most
common use cases (for example finding the closest enclosing function
definition) rely on that.

Summary:
Aligns continuation lines of multi-line comments to the base
indentation level +1:
class A {
/*
* test
*/
void f() {}
};
The first revision is work in progress. The implementation is not yet complete.

The stronger binding of a string ending in :/= does not really make
sense if it is the only character.
Before:
llvm::outs() << aaaaaaaaaaaaaaaaaaaaaaaa
<< "=" << bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb;
After:
llvm::outs() << aaaaaaaaaaaaaaaaaaaaaaaa << "="
<< bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb;

A = new SomeType *[Length]();
Small formatting cleanups with clang-format.
llvm-svn: 176936
1. We now ignore all non-default string literals, including raw
literals.
2. We do not break inside escape sequences any more.
FIXME: We still break in trigraphs.
llvm-svn: 176710
With the cursor located at "I", clang-format would not do anything to:
int a;
I
int b;
With this patch, it reduces the number of empty lines as necessary, and
removes unnecessary whitespace. It does not change/reformat "int a;" or
"int b;".
llvm-svn: 176650
Added two new narrowing matchers:
* hasMethod: aplies a matcher to a CXXRecordDecl's methods until a match is made
or there are no more methods.
* hasCanonicalType: applies a matcher to a QualType's canonicalType.
Enhanced hasOverloadedOperatorName to work on CXXMethodDecl as well as
CXXOperatorCallExpr.
Updated tests and docs.

* Use the term 'command marker', because the semantics of 'backslash' and 'at'
commands are the same. (Talking about 'at commands' makes them look like a
special entity.)
* Sink the flag down into bitfields, reducing the size of AST nodes.
* Change the flag into an enum for clarity. Boolean function parameters are
not very clear.
* Add unittests for new tok::at_command tokens.

Instead of passing NULL on to sub-matcher, just return false. Updated tests and
regenerated docs.

With [] marking the selected range, clang-format invoked on
[ ] int a;
Would so far not reformat anything. With this patch, it formats a
line if its leading whitespace is touched.

In builder type call, we indent to the laster function calls.
However, for the last element of such a call, we don't need to do
so, as that normally just wastes space and does not increase
readability.
Before:
aaaaaa->aaaaaa->aaaaaa( // break
aaaaaa);
aaaaaaaaaaaaaaaaaaaaa->aaaaaaaaaaaaaaaaaaaaaa
->aaaaaaaaaaaaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
After:
aaaaaa->aaaaaa->aaaaaa( // break
aaaaaa);
aaaaaaaaaaaaaaaaaaaaa->aaaaaaaaaaaaaaaaaaaaaa->aaaaaaaaaaaaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
llvm-svn: 176352
We now break at a slash if we do not find a space to break on.
Also fixes a bug where we would go over the limit when breaking the
second line.
llvm-svn: 176350
If we don't find a natural split point (currently space) in a string
literal protruding over the line, we just split at the last possible
point.
llvm-svn: 176349
This does not yet implement the LimitNode approach discussed.
The impact of this is an O(n) in the number of nodes in the AST
reduction of complexity for certain kinds of matchers (as otherwise the
parent map gets recreated for every new MatchFinder).
See FIXMEs in the comments for the direction of future work.
llvm-svn: 176251
Two improvements:
1) Always leave at least one space before "\". Otherwise is can look bad
and there is a risk of unwillingly joining to characters to a different
token.
2) Use the full column limit for single-line #defines.
Fixes llvm.org/PR15148

After some discussions, it seems that this is the better path in
the long run. Does not change Chromium style, as there, bin packing
is forbidden by the style guide.
Also fix two minor bugs wrt. formatting:
1. If a call parameter is a function call itself and is split before
the "." or "->", split before the next parameter.
2. If a call parameter is string literal that has to be split onto
two lines, split before the next parameter.
llvm-svn: 176177
Empty lines followed by line comments are often used to highlight the
comment. Empty lines somewhere else are usually left over from manual or
automatic formatting and should probably be removed.
Before (clang-format would keep):
S s = {
a,
b
};
After:
S s = { a, b };
llvm-svn: 176086
We might want to move towards doing this if the formatting can be
significantly improved, but we need to carefully evaluate the different
situations first.
Before (the string literal was split by clang-format here):
aaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaa, aaaaaa("aaa aaaaa aaa aaa aaaaa aaa "
"aaaaa aaa aaa aaaaaa"));
After:
aaaaaaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaa,
aaaaaa("aaa aaaaa aaa aaa aaaaa aaa aaaaa aaa aaa aaaaaa"));
llvm-svn: 176084
This fixes llvm.org/PR15350.
Before:
Constructor(int Parameter = 0)
: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaa),
aaaaaaaaaaaa(aaaaaaaaaaaaaaaaa) {}
After:
Constructor(int Parameter = 0)
: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaa),
aaaaaaaaaaaa(aaaaaaaaaaaaaaaaa) {}
I think the correct solution is to put the VariablePos into
ParenState, not LineState. Added FIXME.

TemplateSpecializationType doesn't quite have getDecl(). Need to go
through TemplateName to get a TemplateDecl.
Added test cases for the hasDeclaration() overload for
TemplateSpecializationType. Also introduced the type matcher
templateSpecializationType() used by the new hasDeclaration() test case.
Updated LibASTMatchersReference.

Re-introducing r175532. The has_getDecl metafunction didn't compile with
Visual Studio. This revision uses approaches has_getDecl from a
different angle that isn't a problem for Visual Studio.
Added dedicated tests for the metafunction.
