Summary:
Adds actual config file reading to the clang-format utility.
Configuration file name is .clang-format. It is looked up for each input file
in its parent directories starting from immediate one. First found .clang-format
file is used. When using standard input, .clang-format is searched starting from

Before, the actual operator of an overloaded operator declaration was
handled as a binary operator an thus, clang-format could not find valid
formattings for many examples, e.g.:
template <typename AAAAAAA, typename BBBBBBB>
AAAAAAA operator/(const AAAAAAA &a, BBBBBBB &b);
llvm-svn: 181585
With style where the *s go with the type:
Before: typedef bool* (Class:: *Member)() const;
After: typedef bool* (Class::*Member)() const;
llvm-svn: 181439
If the LHS of a binary expression is broken, clang-format should also
break after the operator as otherwise:
- The RHS can be easy to miss
- It can look as if clang-format doesn't understand operator precedence
Before:
bool aaaaaaaaaaaaaaaaaaaaa = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa !=
bbbbbbbbbbbbbbbbbb && ccccccccc == ddddddddddd;
After:
bool aaaaaaaaaaaaaaaaaaaaa =
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa != bbbbbbbbbbbbbbbbbb &&
ccccccccc == ddddddddddd;
As an additional note, clang-format would also be ok with the following
formatting, it just has a higher penalty (IMO correctly so).
bool aaaaaaaaaaaaaaaaaaaaa = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa !=
bbbbbbbbbbbbbbbbbb &&
ccccccccc == ddddddddddd;

LLVM/Clang basically don't use such comments and for Google-style,
include-lines are explicitly exempt from the column limit. Also, for
most cases, where the column limit is violated, the "better" solution
would be to move the comment to before the include, which clang-format
cannot do (yet).
llvm-svn: 181191
clang-format did not indent any declarations/definitions when breaking
after the type. With this change, it indents for all declarations but
does not indent for function definitions, i.e.:
Before:
const SomeLongTypeName&
some_long_variable_name;
typedef SomeLongTypeName
SomeLongTypeAlias;
const SomeLongReturnType*
SomeLongFunctionName();
const SomeLongReturnType*
SomeLongFunctionName() { ... }
After:
const SomeLongTypeName&
some_long_variable_name;
typedef SomeLongTypeName
SomeLongTypeAlias;
const SomeLongReturnType*
SomeLongFunctionName();
const SomeLongReturnType*
SomeLongFunctionName() { ... }
While it might seem inconsistent to indent function declarations, but
not definitions, there are two reasons for that:
- Function declarations are very similar to declarations of function
type variables, so there is another side to consistency to consider.
- There can be many function declarations on subsequent lines and not
indenting can make them harder to identify. Function definitions
are already separated by their body and not indenting
makes the function name slighly easier to find.
llvm-svn: 181187
This seems to be more common in LLVM, Google and Chromium.
Before:

: public BBBBBBBBBBBBBBBBBBBBBBBBBBBBBB,

Deeply nested expressions basically break clang-format's memoization.

This enables formattings like:

In Google style, constructor initializers need to be all on one line or

Previously we'd only detect structural errors on the very first level.
This leads to incorrectly balanced braces not being discovered, and thus
incorrect indentation.
This change fixes the problem by:
- changing the parser to use an error state that can be detected
anywhere inside the productions, for example if we get an eof on
SOME_MACRO({ some block <eof>
- previously we'd never break lines when we discovered a structural
error; now we break even in the case of a structural error if there
are two unwrapped lines within the same line; thus,
void f() { while (true) { g(); y(); } }
will still be re-formatted, even if there's missing braces somewhere
in the file
- still exclude macro definitions from generating structural error;
macro definitions are inbalanced snippets

In conditional expressions, if the condition is split over multiple
lines, also break before both operands.
This prevents formattings like:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ==
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ? b : c;
Which are bad, because they suggestion incorrect operator precedence:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ==
(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ? b : c);
This lead to the discovery that the expression parser incorrectly
handled conditional operators and that it could also handle semicolons
(which in turn reduced the amount of special casing for for-loops). As a
side-effect, we can now apply the bin-packing configuration to the
sections of for-loops.

An unwrapped line can get moved around if there is no newline before
it and the previous line was formatted.
Example:

T *getFETokenInfo() const { return static_cast<T*>(FETokenInfo); }
"return .." is the second unwrapped line in this scenario. I does not
touch any reformatted region. Thus, the result of formatting is:
template <typename T> T *getFETokenInfo() const { return static_cast<T *>(FETokenInfo); }
