2013-04-25Improve clang-format's memoization behavior.Daniel Jasper
Deeply nested expressions basically break clang-format's memoization. This patch slightly improves the situations and makes expressions like aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa( aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa( aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa( aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa( aaaaa(aaaaa()))))))))))))))))))))))))))))))))))))))); work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180264 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-24Fix comment alignment behavior.Daniel Jasper
In the following snippet, clang-format incorrectly aligned the trailing comment, when only the last line was formatted: int aaaaaa; // comment int b; int c; // Formatting only this line moved this comment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180173 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-22Fix bin-packing behavior of constructor initialziers.Daniel Jasper
In Google style, constructor initializers need to be all on one line or one initializer per line if that does not fit. Without this patch, this non-bin-packing-behavior incorrectly extends to the parameters of the initializers.

2013-04-17Unified token breaking logic: support for line comments.Alexander Kornienko
Summary: Added BreakableLineComment, moved common code from BreakableBlockComment to newly added BreakableComment. As a side-effect of the rewrite, found another problem with escaped newlines and had to change code which removes trailing whitespace from line comments not to break after this patch.

2013-04-15Unified token breaking logic for strings and block comments.Alexander Kornienko
Summary: Both strings and block comments are broken into lines in breakProtrudingToken. Logic specific for strings or block comments is abstracted in implementations of the BreakToken interface. Among other goodness, this change fixes placement of backslashes after a block comment inside a preprocessor directive (see removed FIXMEs in unit tests). The code is far from being polished, and some parts of it will be changed for line comments support.

2013-04-12Revamps structural error detection / handling.Manuel Klimek
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 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179379 91177308-0d34-0410-b5e6-96231b3b80d8

Function declarations are now broken with the following preferences: 1) break amongst arguments. 2) break after return type. 3) break after (. 4) break before after nested name specifiers.
