* clang-format: [JS] generator and async functions.Martin Probst2016-04-241-0/+34
| | | | | | | | | | | | | | | For generators, see: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Iterators_and_generators async functions are not quite in the spec yet, but stage 3 and already widely used: http://tc39.github.io/ecmascript-asyncawait/ Reviewers: djasper Subscribers: klimek Differential Revision: http://reviews.llvm.org/D19204 llvm-svn: 267368
* clang-format: [JS] support `interface` as a free standing identifier.Martin Probst2016-04-191-0/+3
| | | | | | | | | | | | | | | Summary: `interface` can be used as a fee standing identifier in JavaScript/TypeScript. This change uses the heuristic of whether it's followed by another identifier as an indication.

* Summary:Martin Probst2016-04-191-1/+14
| | | | | | | | | | | | | | | | | | | clang-format: [JS] unit tests for type aliases. Also adds a test for "foo as bar" casts. Spec: https://github.com/Microsoft/TypeScript/blob/master/doc/spec.md#3.10 These are already handled correctly. Reviewers: djasper Subscribers: cfe-commits, klimek Differential Revision: http://reviews.llvm.org/D19206 llvm-svn: 266744
* clang-format: [JS] simplify import/export.Martin Probst2016-04-191-0/+4
| | | | | | | | | | | | | | | | | | | Summary: Change `import` and `export` parsing to special case the renaming syntax (`import x, {y as bar} ...`, `export {x}`) and otherwise just parse a regular structural element. This simplifies the code a bit and should be more correct - it's easier to recognise the specific import syntax than to recognise arbitrary expressions and declarations.

* clang-format: [JS] Test for parameter annotations.Martin Probst2016-04-111-0/+3
| | | | | | | | | | | | Summary: Just to ensure no regressions, this already works fine. Reviewers: djasper Subscribers: cfe-commits, klimek Differential Revision: http://reviews.llvm.org/D18950 llvm-svn: 265922

* clang-format: [JS] do not wrap ES6 imports/exports.Daniel Jasper2016-03-221-17/+15
| | | | | | | | | "import ... from '...';" and "export ... from '...';" should be treated the same as goog.require/provide/module/forwardDeclare calls. Patch by Martin Probst. llvm-svn: 264055
* clang-format: [JS] no space in union and intersection types.Daniel Jasper2016-03-211-0/+8
| | | | | | | | | The operators | and & in types, as opposed to the bitwise operators, should not have whitespace around them (e.g. `Foo<Bar|Baz>`). Patch by Martin Probst. Thank you. llvm-svn: 263961
* clang-format: [JS] Fix incorrect spacing around contextual keywords.Daniel Jasper2016-03-171-0/+4
| | | | | | | | | | Before: x.of (); After: x.of(); llvm-svn: 263710
* clang-format: [JS] Handle certain cases of ASI.Daniel Jasper2016-03-141-66/+121
| | | | | | | | | | | | | | Automatic Semicolon Insertion can only be properly handled by parsing source code. However conservatively catching just a few, common situations prevents breaking code during development, which greatly improves usability. JS code should still use semicolons, and ASI code should be flagged by a compiler or linter. Patch by Martin Probst. Thank you. llvm-svn: 263470
* clang-format: [JS] Support destructuring assignments in for loops.Daniel Jasper2016-03-051-0/+4
| | | | | | | | | | | | Before: for (let { a, b } of x) { } After: for (let {a, b} of x) { } llvm-svn: 262776
* clang-format: [JS] Optionally re-quote string literals.Daniel Jasper2016-03-021-2/+33
| | | | | | | | | | | | | | | | | | | | | Turns "foo" into 'foo' (or vice versa, depending on configuration). This makes it more convenient to follow the Google JavaScript style guide: https://google.github.io/styleguide/javascriptguide.xml?showone=Strings#Strings This functionality is behind the option "JavaScriptQuotes", which can be: * "leave" (no re-quoting) * "single" (change to single quotes) * "double" (change to double quotes) This also changes single quoted JavaScript string literals to be treated as tok::string_literal, not tok::char_literal, which fixes two unrelated tests. Patch by Martin Probst. Thank you. llvm-svn: 262534
* clang-format: [JS] Support quoted object literal keys.Daniel Jasper2016-03-011-0/+7
| | | | | | | | | | | | | | | | | Before: var x = { a: a, b: b, 'c': c, }; After: var x = { a: a, b: b, 'c': c, }; llvm-svn: 262291
* clang-format: [JS] treat forwardDeclare as an import/export statement.Daniel Jasper2016-02-221-0/+2
| | | | | | Patch by Martin Probst. Thank you. llvm-svn: 261528
* clang-format: [JS] Support for (.. of ..) loops.Daniel Jasper2016-02-111-0/+3
| | | | | | | | | | Before: for (var i of[2, 3]) {} After: for (var i of [2, 3]) {} llvm-svn: 260518
* clang-format: [JS] Don't count shortened object literals as blocks.Daniel Jasper2016-02-071-0/+5
| | | | | | | | | | | | | | | Before: f({a}, () => { g(); // }); After: f({a}, () => { g(); // }); llvm-svn: 260060
* clang-format: [JS/TypeScript] Support "enum" as an optional property name, too.Daniel Jasper2016-02-031-0/+1
| | | | | | | | | | | Before: enum?: string []; After: enum?: string[]; llvm-svn: 259628

* clang-format: [JS] Fix incorrect line break leading to semicolon insertion.Daniel Jasper2016-01-141-0/+4
| | | | | | | | | | | | | | | | clang-format only works for JavaScript code, if all the semicolons are present anyway, so this linebreak can never be desired. Before (with appropriate statement lengths or column limit): return [ aaa ]; After: return [ aaaa ]; llvm-svn: 257741
* clang-format: [ObjC+JS] Allow bin-packing of array literals.Daniel Jasper2016-01-131-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After reading the style guides again, they don't actually say how to pack or not pack array literals. Based on some user reports, array initializers can unnecessarily get quite long if they contain many small elements. Array literals with trailing commas are still formatted one per line so that users have a way to opt out of the packing. Before: var array = [ aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa ]; After: var array = [ aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa, aaaaaa ]; llvm-svn: 257615
* clang-format: [JS] Support exporting abstract classes.Daniel Jasper2016-01-121-0/+1
| | | | | | | | | | | Before: export abstract class X {y: number;} (and all sorts of other havoc in more complicated cases). After: export abstract class X { y: number; } llvm-svn: 257451

* clang-format: Fix the counting of leading whitespace in tok::unknown tokensDaniel Jasper2016-01-091-0/+3
| | | | | | | | Previously, all whitespace characters would increase the starting column, which doesn't make sense. This fixes a problem, e.g. with the length calculation in JS template strings. llvm-svn: 257267
* clang-format: [JS] Support semicolons in TypeScript's TypeMemberLists.Daniel Jasper2016-01-091-0/+8
| | | | | | | | | | | | | | Before: var x: { a: string; b: number; } = {}; After: var x: {a: string; b: number;} = {}; llvm-svn: 257255
* clang-format: [JS] Prefer wrapping before the TypeScript return typeDaniel Jasper2016-01-081-0/+3
| | | | | | | | | | | | | | over wrapping before parameters. Before: function someFunc( args: string[]): {longReturnValue: string[]} {} After: function someFunc(args: string[]): {longReturnValue: string[]} {} llvm-svn: 257162

* clang-format: Fix corner case in one-per-line formatting.Daniel Jasper2016-01-071-0/+5
| | | | | | | | | | | | | | | | | | | Before (example is JS, but also applies to C++): return [ aaaa() .bbbbbbbb('A'), aaaa().bbbbbbbb('B'), aaaa().bbbbbbbb('C'), ]; After: return [ aaaa().bbbbbbbb('A'), aaaa().bbbbbbbb('B'), aaaa().bbbbbbbb('C'), ]; llvm-svn: 257079

* clang-format: [JS] Improve empty array literal detection.Daniel Jasper2016-01-041-0/+2
| | | | | | | | | | | | | | | Previously, the [] in the following example were recognized as an array subscript leading to weird indentation. Before: var aaaa = aaaaa || // wrap []; After: var aaaa = aaaaa || // wrap []; llvm-svn: 256753
* clang-format: [JS] Support TypeScript 1.6 user defined type guards.Daniel Jasper2015-12-301-0/+8
| | | | | | | | | | | | | | | | Before: function foo(check: Object): check is{foo: string, bar: string, baz: string, foobar: string} { return 'bar' in check; } After: function foo(check: Object): check is {foo: string, bar: string, baz: string, foobar: string} { return 'bar' in check; } llvm-svn: 256631

* clang-format: Add an additional value to AlignAfterOpenBracket: AlwaysBreak.Daniel Jasper2015-10-271-49/+63
| | | | | | | | | | | | | | | | | | | | Summary: If this option is set, clang-format will always insert a line wrap, e.g. before the first parameter of a function call unless all parameters fit on the same line. This obviates the need to make a decision on the alignment itself. Use this style for Google's JavaScript style and add some minor tweaks to correctly handle nested blocks etc. with it. Don't use this option for for/while loops. Reviewers: klimek Subscribers: klimek, cfe-commits Differential Revision: http://reviews.llvm.org/D14104 llvm-svn: 251405
* clang-format: [JS] Handle string literals spanning character classes.Daniel Jasper2015-10-181-0/+10
| | | | | | | | | | | | | | | If a RegExp contains a character group with a quote (/["]/), the trailing end of it is first tokenized as a string literal, which leads to the merging code seeing an unbalanced bracket. This change parses regex literals from the left hand side. That simplifies the parsing code and also allows correctly handling escapes and character classes, hopefully correctly parsing all regex literals. Patch by Martin Probst, thank you.

* clang-format: [JS] handle character classes in regexes.Daniel Jasper2015-10-121-0/+6
