+ | === Scientific Results | ||
+ | |||
+ | == WP 1: Reflective Foundations == | ||
+ | Progress on a new iteration on the reflective layer and metaobject protocol for Pharo: We have implemented the Slots Mechanism in Pharo, which resulted in a first-class reification of instance variables and their accessing through assignment and reading. This allows us to hook into reading and writing of instance variables and perform meta-level operations on them, e.g., adding breakpoints to the reading of a specific instance var, or a transparent notification mechanism for when a specific instance variable is written. The latter can be used, e.g., in WP3 to dynamically update a visualization of the object that contains the instance variable whenever the variable changes. | ||
+ | Reflective operations in the form of meta-links can be added to any expression tree. All variables can now be annotated with meta data. Reflectivity has been improved to allow Meta- Links to be put on First Class Variables. All work has been integrated in Pharo5 development and is used already by other projects of RMOD and a research project of the University of Lugano/ | ||
+ | The object layout functionality of Pharo allowed us to work on supporting C-Types. The Opal Compiler was extended with primitive types and to emit new low-level bytecode instructions. Combined, this allows performance for use-cases like 2D and 3D frameworks to be speed up by 50-400% [13]. | ||
+ | |||
+ | |||
+ | == WP 2: Visualizations Engines == | ||
+ | Two complementaries axes were investigated. Roassal 2D is a visualization engine to render data. Roassal 2D is employed to visualize any arbitrary set of data, including software-related data [5, 9] (e.g., source code, module dependencies), | ||
+ | The second axis is the visualization in 3D. For that purpose, we have improved the FFI support of Pharo to use external libraries. With that, we created binding to SDL2 which allowed to move the window management code from the Virtual Machine to Pharo (OSWindow). The 2D infrastructure work (OSWindow) has been taken up by another Project (Inria in collaboration with Thales). It has been extended with multi-touch support and a gesture engine. Besides pre-defined low level gestures (e.g., pinch or multi-finger swipe), the engine is extensible with user-defined gestures. The Woden 3D graphics engine is a first demo that uses this foundation to bring the ideas of Roassal to 3D. The new next generation graphics frameworks like Metal and Vulcan where the driving force to revisit Woden. The new framework Woden 2 uses the lowcode subsystem (see WP1) for a new generation, high perfomance 3D framework for Pharo. This will be the foundation of Roassal3D soon. Woden has already seen use outside of the PLOMO project, for example it is used for experiments with virtual reality at a large french multi-national company. | ||

+ | == WP 3: Tools for Analyzing Dynamic Information == | ||
+ | Live Robot Programming (LRP) [10] as a case for the first two points of WP3: Visualization to navigate and browse source code, Visualizing dynamic information to navigate source code. Firstly, in LRP the (Domain-Specific) source code is shown in a (Domain-Specific) visualization made in Roassal2 and Spec. Clicking on the entities in the visual representation causes a navigation action in the source code of the program. Secondly, in the LRP visualization the dynamic information of the state of variables in scope is shown, as well as which piece of the code is currently running, and this is partially enabled by Slots. The visit of Marcus Denker to Chile in spring 2015 helped to make serious progress on the base implementation infrastructure: | ||
+ | We worked on refining the user interface framework Spec [4,16], together with its integra- tion with the visualization of dynamic information using Roassal as well as the GT Inspector framework for the analysis of live objects. The goal is to allow a developer to build his own custom user interface for the visualization of dynamic information, | ||

+ | === Work outside of work packages === | ||
+ | Close proximity among the researchers also allowed work outside of the work packages to be started. One example is a preliminary effort in speeding up collections handling [12], another the work on identifying classes in legacy JavaScript code [15]. | ||
