* Rework the AST for Literals and destructuring expressionsLars Knoll2018-04-271-103/+55
| | | | | | | | | | | | | | | | | Array/ObjectLiterals and destructuring expressions are syntactically very similar. In some cases (when using a destructuring expression as the lhs of an assigment), the parser needs to convert the literal into a destructuring expression. To support these, use the same data structures for both in the AST. Those Patterns can be converted with little additional work from a Literal to an AssignmentPattern and be used in all places where we need destructuring in addition to literals.

* Rename Array/ObjectLiteral to Array/ObjectPattern in the ASTLars Knoll2018-04-271-2/+2
| | | | | | | | | | | | To get a consistent representation in the AST, we need to unify the AST that is generated by theObjectLiterals, ObjectBindingPattern and ObjectAssignmentPattern rules in the grammar. Like this we can avoid having to reparse part of the source code, and instead replace this with consistency checks once we know which of the three grammars are supposed to apply.

* Bring JS grammar in line with ES7 specLars Knoll2018-04-251-41/+21
| | | | | | | | | | | | | | | | | | | | | | | This basically updates all grammar rules in the qqmljs.g file to be in line with the ES7 specification. Some special handling for the lookahead rules appearing in the spec was needed and is implemented through empty lookahead rules in the grammar, that might push an additional token into the token stream. Renamed some classes in the AST to be in line with the names used in ES7, and removed some other ones (SourceElements) that are no longer used. The ES7 grammar rules contain lots of variations of the base rules (with In/Return/Yield/Default suffixes). With the exception of the In and Default rules, these are implemented through state tracking in the parser and lexer.

* Add support for ES6 template stringsLars Knoll2018-04-251-0/+8
| | | | | | | | | | | | | This requires a bit of bookeeping in the lexer, as we can have arbitrary expressions inside the ${...}. To make this work, keep a stack of template states, in which we count the unclosed braces to match up with the correct closing brace. Implements support for `...`. Expressions of the type Foo`...` and Foo()`...` will come in follow-up commits. Change-Id: Ia332796cfb77895583d0093732e6f56c8b0662c9 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* use nullptr consistently (clang-tidy)Shawn Rutledge2018-02-261-4/+4
| | | | | | | | | | | | | From now on we prefer nullptr instead of 0 to clarify cases where we are assigning or testing a pointer rather than a numeric zero. Also, replaced cases where 0 was passed as Qt::KeyboardModifiers with Qt::NoModifier (clang-tidy replaced them with nullptr, which waas wrong, so it was just as well to make the tests more readable rather than to revert those lines).

* Add Singleton support for QMLAntti Piira2013-09-211-3/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces Singleton support for QML (Composite Singleton). For now, the Singleton support is only availabe for QML types in modules or (remote and local) directories with qmldir file. However, in the future this support may be expanded to arbitrary QML file imports without by leaving out the qmldir requirement. You define a QML type as a Singleton with the following two steps: 1. By adding a pragma Singleton to a type's QML file: pragma Singleton The pragma and import statements can be mixed and their order does not matter. Singleton is the only supported pragma for now. Others will generate errors. 2. By specifying a qmldir file for the directory of your imported type and prepending the type with "singleton" keyword as follows: singleton TestTypeSingleton TestTypeSingleton.qml Alternatively you may specify a qmldir file for a module and specify your type as a singleton as follows: singleton TestTypeSingleton 1.0 TestTypeSingleton.qml Composite Singletons may be included in a module and may be used with a local namespace qualifier when imported with: "import xxx as NameSpace" A singleton instance is created at first use and stored into the QmlEngine (one instance per engine) and eventually released by the engine's destructor. CompositeSingletonType has a dual nature and will return true to both isComposite() and isSingleton() calls. In most cases its enough to check for just isComposite() or isSingleton(). However, there is a isCompositeSingleton() available as well. I used "qlalr --no-debug --no-lines --qt qqmljs.g" to generate the qqmljsparser and qqmljsgrammar files from qqmljs.g. Unit tests are included. Change-Id: I91b303612c5e132143b325b9a8f982e9355bc90e Reviewed-by: Alan Alpert (Personal) <416365416c@gmail.com>
