* Compile binding expressions in the QQmlCompilerSimon Hausmann2013-10-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This is done by re-using the JS code generator from the new compiler. A few bugs were fixed on the way: * The index into the compiledData->runtimeFunctions array is not the same as the function index when they are collected (from the AST), as for example binding expressions may create extra V4IR::Function objects that break the 1:1 mapping. Therefore the JS code gen will return a mapping from incoming function index to V4IR::Module::Function (and thus runtimeFunction) * Binding expressions in the old backend get usually unpacked from their ExpressionStatement node. The reference to that node is lost, and instead of trying to preserve it, we simply synthesize it again. This won't be necessary anymore with the new compiler in the future. * Commit 1c29d63d6045cf9d58cbc0f850de8fa50bf75d09 ensured to always look up locals by name, and so we have to do the same when initializing the closures of nested functions inside binding expressions (in qv4codegen.cpp) * Had to change the Qml debugger service auto-test, which does toString() on a function that is now compiled. Even if we implemented FunctionPrototype::toString() to do what v8 does by extracting the string from the file, it wouldn't help in this test, because it feeds the input from a string instead of a file. * In tst_parserstress we now end up compiling all JS code, which previously was only parsed. This triggers some bugs in the SSA handling. Those tests are skipped and tracked in QTBUG-34047 Change-Id: I44df51085510da0fd3d99eb5f1c7d4d17bcffdcf Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* Add Singleton support for QMLAntti Piira2013-09-2110-1120/+1373
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
