* Long live QML inline componentsFabian Kosmale2020-01-231-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | [ChangeLog][QtQml] It is now possible to declare new QML components in a QML file via the component keyword. They can be used just as if they were declared in another file, with the only difference that the type name needs to be prefixed with the name of the containing type outside of the file were the inline component has been declared. Notably, inline components are not closures: In the following example, the output would be 42 // MyItem.qml Item { property int i: 33 component IC: Item { Component.onCompleted: console.log(i) } } // user.qml Item { property int i: 42 MyItem.IC {} } Fixes: QTBUG-79382 Change-Id: I6a5ffc43f093a76323f435cfee9bab217781b8f5 Reviewed-by: Ulf Hermann <ulf.hermann@qt.io>
* Introduce required properties to QMLFabian Kosmale2019-09-091-0/+12
| | | | | | | | | | | | | | | | | | | [ChangeLog][QtQml] "required" is now a (contextual) keyword in QML, and users can mark properties with it to specify that those properties must be set when the component gets instantiated. This can be done either declaratively via standard property bindings from QML, or imperatively by using the functions to set initial properties (QQmlCompoent::setInitalProperties and related functions in C++, Qt.createObject, Loader.setSource,... in QML/JS). Logic has been added to QQmlComponent::create and the various QQmlIncubator classes to verify that the required properties were set. If properties marked as required are not set, a warning will be printed at runtime, and the component will not be created.

* Fix grammar for ES modulesLars Knoll2018-08-021-2/+2
| | | | | | | | | | | | * Always parse 'import' as a keyword, as it is now one in Qml and ES. * Always parse 'as' as keyword but allow it as identifier using the same trick as for the other keywords. This fixes basic import statements such as import "foo.mjs" as bar but still allows funny variations such as import "foo.mjs" as as.

* Bring JS grammar in line with ES7 specLars Knoll2018-04-251-1/+10
| | | | | | | | | | | | | | | | | | | | | | | 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 yield as a keywordLars Knoll2018-04-251-54/+65
| | | | | | | | | | | | It's not a keyword outside of generator functions, so extend the qmlmode boolean on the lexer to become a more general parsemode that we can use to also turn the yield keyword on and of. The parser can then set the flag when it enters the body of a generator function. Change-Id: Ibf792d4c7c567d825c6706f7b4997362c87fc575 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

* Codegen: Disallow const declaration without an initializer expressionRobin Burchell2017-02-021-1/+1
| | | | | | | | | | | | | | | | | | | | | This seems to match up with the spec behavior. 13.3.1.1 (Static Semantics: Early Errors) says: It is a Syntax Error if Initializer is not present and IsConstantDeclaration of the LexicalDeclaration containing this production is true. In addition, we also allow "const" to be used in JS mode too. We don't yet fully support the semantics, but as it's there, why not let it work. [ChangeLog][QtQml] "const" variable declarations are now available in JS as well as QML mode. [ChangeLog][QtQml] "const" variable declarations now require an initializer, bringing them closer to the required spec behavior.

* Add Singleton support for QMLAntti Piira2013-09-211-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
