* clang-format: [JS] Array literal detection fix #3.Daniel Jasper2015-06-021-2/+2
| | | | llvm-svn: 238839
* clang-format: [JS] Fix another regression when detecting array literals.Daniel Jasper2015-06-021-1/+2

* Remove error message when using the fallback style.Manuel Klimek2015-06-021-2/+0
| | | | llvm-svn: 238822
* clang-format: [JS] Making arrow function wrapping more consistent.Daniel Jasper2015-06-012-10/+6
| | | | | | | | | | | | | | | | | | | | | | Before: someFunction(() => { doSomething(); // break }) .doSomethingElse( // 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. llvm-svn: 238736
* [Format] Move UnwrappedLines instead of copying.Benjamin Kramer2015-05-311-7/+4
| | | | | | No functional change intended. llvm-svn: 238673
* clang-format: NFC. Cleanup after r237895.Daniel Jasper2015-05-312-31/+8
| | | | | | | | | | | Specifically adhere to LLVM Coding Standards (no 'else' after return/break/continue) and remove yet another implementation of paren counting. We already have enough of those in the UnwrappedLineParser. No functional changes intended. llvm-svn: 238672
* clang-format: [JS] Fix line breaks in computed property names.Daniel Jasper2015-05-311-1/+1
| | | | | | | | | | | | | | | | | | | Before: let foo = { [someLongKeyHere]: 1, someOtherLongKeyHere: 2, [keyLongEnoughToWrap]: 3, lastLongKey: 4 }; After: let foo = { [someLongKeyHere]: 1, someOtherLongKeyHere: 2, [keyLongEnoughToWrap]: 3, lastLongKey: 4 }; llvm-svn: 238671
* clang-format: [JS] Support ES6 computed property names.Daniel Jasper2015-05-292-0/+4
| | | | | | | | | | | | | | | | Before: var x = { [a]: 1, b: 2 }; After: var x = { [a]: 1, b: 2 }; llvm-svn: 238544
* [Format] Skip creating temporary std::strings when filling another string.Benjamin Kramer2015-05-281-6/+6
| | | | | | No functional change intended. llvm-svn: 238466
* clang-format: Lower binding strengths created by the [] created by ObjCDaniel Jasper2015-05-281-13/+17
| | | | | | | | | | | | | | | | | | method expressions and array literals. They should not bind stronger than regular parentheses or the braces of braced lists. Specific test case in JavaScript: Before: var aaaaa: List< SomeThing> = [new SomeThingAAAAAAAAAAAA(), new SomeThingBBBBBBBBB()]; After: var aaaaa: List<SomeThing> = [ new SomeThingAAAAAAAAAAAA(), new SomeThingBBBBBBBBB() ]; llvm-svn: 238400
* clang-format: [JS] Fix incorrect detection of ternary expressions.Daniel Jasper2015-05-271-4/+3
| | | | | | | | | | | | | A definintion like this could not be formatted at all: constructor({aa}: { aa?: string, aaaaaaaa?: string, aaaaaaaaaaaaaaa?: boolean, aaaaaa?: List<string> }) { } llvm-svn: 238291
* clang-format: Fix false positive in function annotation detection.Daniel Jasper2015-05-271-1/+1
| | | | llvm-svn: 238285
* clang-format: Guard the bin-packing in braced lists on BinPackArgumentsDaniel Jasper2015-05-262-4/+4
| | | | | | | | instead of BinPackParameters. Braced lists are used as constructor calls in many places and so the bin-packing should follow what is done for other calls and not what is done for function declarations. llvm-svn: 238184
* clang-format: [JS] Support ES6 spread operator.Daniel Jasper2015-05-261-0/+2
| | | | | | | | | | | | | | Specifically, don't add a space before it. Before: someFunction(... a); var x = [1, 2, ... a]; After: someFunction(...a); var x = [1, 2, ...a]; llvm-svn: 238183
* clang-format: Fix child-formatting in macros.Daniel Jasper2015-05-261-4/+8
| | | | | | | | | | | | | | | This fixes a case where the column limit was incorrectly calculated leading to a macro like this: #define A \ [] { \ xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx( \ xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx); \ } exceeding the column limit. llvm-svn: 238182
* clang-format: [JS] Better support for fat arrows.Manuel Klimek2015-05-214-18/+70
| | | | | | | | | | | | Assigns a token type (TT_JsFatArrow) to => tokens, and uses that to more easily recognize and format fat arrow functions. Improves function parsing to better recognize formal parameter lists and return type declarations. Recognizes arrow functions and parse function bodies as child blocks. Patch by Martin Probst. llvm-svn: 237895
* clang-format: Add space in function pointers with SpaceBeforeParens=AlwaysAnders Waldenborg2015-05-191-1/+1
| | | | | | | | | "void (*my_function)(void)" should become "void (*my_function) (void)" when SpaceBeforeParens is set to 'Always' Differential Revision: http://reviews.llvm.org/D9835 llvm-svn: 237704
* clang-format: Improve *-detection.Daniel Jasper2015-05-191-0/+3
| | | | | | | | | | | | Before: S << a *(10); After: S << a * (10); This fixes llvm.org/PR16500. llvm-svn: 237690

| | | | | | | | | | | | | | | | | | Before: for (SmallVectorImpl<TemplateIdAnnotationn *>::iterator I = Container.begin(), E = Container.end(); I != E; ++I) After: for (SmallVectorImpl<TemplateIdAnnotationn *>::iterator I = Container.begin(), E = Container.end(); I != E; ++I) This fixes llvm.org/PR23544. llvm-svn: 237688
* clang-format: Support #include_nextDaniel Jasper2015-05-191-0/+1
| | | | | | | | | | | | Before: #include_next < test.h > After: #include_next <test.h> This fixes llvm.org/PR23500 llvm-svn: 237686
* clang-format: Correctly detect casts to qualified types.Daniel Jasper2015-05-191-1/+2
| | | | | | | | | | | | Before: ns::E f() { return (ns::E) - 1; } After: ns::E f() { return (ns::E)-1; } This fixes llvm.org/PR23503. llvm-svn: 237684
* clang-format: Fix regression caused by r237244.Daniel Jasper2015-05-191-1/+1
| | | | | | | | | | | | | | | Before: [call aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa. aaaaaaaa]; After: [call aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa .aaaaaaaa]; This merely papers over the fact that we aren't parsing ObjC method calls correctly. Also, the indentation is weird. llvm-svn: 237681

* clang-format: Improve detection of macros annotating functions.Daniel Jasper2015-05-183-21/+17
| | | | | | | | | | | | | | | | Before: ASSERT("aaaaaaaaaaaaaaa") << aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa << bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb; After: ASSERT("aaaaaaaaaaaaaaa") << aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa << bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb; Also cleanup implementation a bit and only mark closing parenthesis of these annotations. llvm-svn: 237567
* clang-format: Allow braced initializers in template arguments of classDaniel Jasper2015-05-182-12/+14
| | | | | | | | | | | | | | specializations. Before: template <class T> struct S < std::is_arithmetic<T> { } > {}; After: template <class T> struct S<std::is_arithmetic<T>{}> {}; llvm-svn: 237565

* clang-format: Improve line wrapping around << operators.Daniel Jasper2015-05-171-1/+2
| | | | | | | | | | | | | | | | | | Generally, clang-format tries to keep label-value pairs on a single line for stream operators. However, we should not do that if there is just a single such pair, as that doesn't help much. Before: llvm::errs() << "aaaaaaaaaaaa: " << aaaaaaa(aaaaaaaaa, aaaaaaaaa); After: llvm::errs() << "aaaaaaaaaaaa: " << aaaaaaa(aaaaaaaaa, aaaaaaaaa); Also remove old test case that was testing actual behavior any more. llvm-svn: 237535
* clang-format: Slightly change format decisions around macro annotations.Daniel Jasper2015-05-151-1/+1
| | | | | | | | | | | | Before: bool aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa GUARDED_BY(aaaaaaaaaaaa) = aaaaaaaaaaaaaaaaaaaaaaaaa; After: bool aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa GUARDED_BY(aaaaaaaaaaaa) = aaaaaaaaaaaaaaaaaaaaaaaaa; llvm-svn: 237430
* clang-format: Don't use column layout in lists that have separatingDaniel Jasper2015-05-151-5/+7
| | | | | | | | comments. At some point, we might to want to a layout with a different number of columns instead, but at the moment, this causes more confusion than it's worth. llvm-svn: 237427

| | | | | | | | | | Before: [self aaaaa:(1 + 2)bbbbb:3]; After: [self aaaaa:(1 + 2) bbbbb:3]; llvm-svn: 237424
* clang-format: Improve nested block / lambda indentation when wrappingDaniel Jasper2015-05-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | before binary/ternary operators. Basically, it doesn't seem right to indent a nested block aligned to a binary or ternary operator. Before: int i = aaaaaa ? 1 // : [] { return 2; // }(); llvm::errs() << "number of twos is " << std::count_if(v.begin(), v.end(), [](int x) { return x == 2; // force break }); After: int i = aaaaaa ? 1 // : [] { return 2; // }(); llvm::errs() << "number of twos is " << std::count_if(v.begin(), v.end(), [](int x) { return x == 2; // force break }); llvm-svn: 237263

* Refactor clang-format's formatter.Manuel Klimek2015-05-122-164/+220
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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' }); llvm-svn: 237104

* clang-format: Improve column layout.Daniel Jasper2015-05-111-14/+18
| | | | | | | | | | | | | | | | | | | | | | Specifically, calculate the deviation between the shortest and longest element (which is used to prevent excessive whitespace) per column, not overall. This automatically handles the corner cases of a single column and a single row so that the actualy implementation becomes simpler. Before: vector<int> x = {1, aaaaaaaaaaaaaaaaaaaaaa, 2, bbbbbbbbbbbbbbbbbbbbbb, 3, cccccccccccccccccccccc}; After: vector<int> x = {1, aaaaaaaaaaaaaaaaaaaaaa, 2, bbbbbbbbbbbbbbbbbbbbbb, 3, cccccccccccccccccccccc}; llvm-svn: 236992
