SPLLIFT — Statically Analyzing Software Product Lines in Minutes Instead of Years

Qt Framework
About Qt Qt is a framework to develop cross-platform applications. Currently, the supported platforms are Windows, Linux, macOS, Android, iOS, Embedded Linux and some others. Genarally, it means that the programmer may develop the code on one platform but compile, link and run it on another platform. But it also means that Qt needs help: to develop software it must cooperate with development tools on specific platforms, for example in case of Windows with Visual Studio. Qt is well-known for its tools for developing graphical user interfaces (GUI) , but it also provides powerful tools for threads, networking and communication (Bluetooth, serial port, web), 3D graphics, multimedia, SQL databases, etc. Qt has its own Integrated Development Environment (IDE): QtCreator. History: 1991: version 1.0 as cross-platform GUI programming toolkit was developed and implemented by TrollTech (Norway). 2005: version 4.0 was a big step ahead but the compatibility with older versions was lost. 2008: TrollTech was sold to Nokia. 2012: Nokia Qt division was sold to Digia (Finland). 2014: Digia transferred the Qt business to Qt Company. The latest Long Term Support (LTS) version is 5.12. Official website: https://www.qt.io/ Installation The link is https://www.qt.io/download. Select the non-commercial and open source version. It may be possible that you must register yourself creating a new passworded account. Select the latest stable release and the C/C++ development system(s) you are going to use. Tip: the Qt installer proposes to store the stuff in folder C:\Qt. To avoid later complications, agree. -

Sinkarenko, S. Zanzottera, V. Baggiolini, BE-CO-APS, CERN, Geneva, Switzerland Abstract technology choices for GUI, even at the cost of not using Java – our core technology – for GUIs anymore. For more than 15 years, operational GUIs for accelerator controls and some lab applications for equipment experts have been developed in Java, first with Swing and more CRITERIA FOR SELECTING A NEW GUI recently with JavaFX. In March 2018, Oracle announced that Java GUIs were not part of their strategy anymore [1]. TECHNOLOGY They will not ship JavaFX after Java 8 and there are hints In our evaluation of GUI technologies, we considered that they would like to get rid of Swing as well. the following criteria: This was a wakeup call for us. We took the opportunity • Technical match: suitability for Desktop GUI to reconsider all technical options for developing development and good integration with the existing operational GUIs. Our options ranged from sticking with controls environment (Linux, Java, C/C++) and the JavaFX, over using the Qt framework (either using PyQt APIs to the control system; or developing our own Java Bindings to Qt), to using Web • Popularity among our current and future developers: technology both in a browser and in native desktop little (additional) learning effort, attractiveness for new applications. -

In this paper, we will discuss ten programming languages: C++, C#, Java, Groovy, JavaScript, PHP, Schalar, Scheme, Haskell and AspectJ. We summarize and compare these ten languages on ten different criterion. For example, Default more secure programming practices, Web applications development, OO-based abstraction and etc. At the end, we will give our conclusion that which languages are suitable and which are not for using in some cases. We will also provide evidence and our analysis on why some language are better than other or have advantages over the other on some criterion. 1 Introduction Since there are hundreds of programming languages existing nowadays, it is impossible and inefficient -
