Using Spirit X3 to Write Parsers
by Michael Caisse
Summary of the talk:
Parsing is a common problem in many domains. The complexity of using a library often pushes developers to ad-hoc solutions utilizing std::string manipulations, regular expressions, or nested if/switch statements. Most “quick hack” implementations are unmaintainable.
Spirit provides a Domain Specific Embedded Language (DSEL) that allows grammars to be described in a natural and declarative manner just like writing PEG or EBNF directly in your C++ code. X3 is the third major release of the Spirit library and improves both compile and run times while simplifying the much of the library.
In this tutorial session you will be introduced to Spirit X3, attribute parsing, and variety of tips to writing efficient and maintainable parsers. We will build a JSON parser during the session to illustrate techniques and usage of the library. This session is applicable toward anyone needing to parse data.

Modern User Interfaces for C++
by Milian Wolff
Summary of the talk:
The C++ language evolved significantly in the recent past, and so did many frameworks and libraries in the big ecosystem surrounding it.
For twenty years now, Qt is being used on a multitude of platforms to create native looking, compelling graphical user interfaces.
It offers C++ libraries and tools for building desktop, mobile and embedded applications. Qt gives engineers APIs for developing using two dimensional controls, integrating 3D using OpenGL, embedding web content, as well as a new declarative domain-specific language called QML, which is extensible using C++. Qt is also much more than a UI toolkit and provides a multitude of helper libraries for various use-cases, such as localization, database access, XML and JSON parsing and much more.
During this talk, I will give an introduction to Qt and present its capabilities in how it can be utilized to write modern UIs using C++, both in 2D as well as 3D. Additionally, I will show how some of its features, like the integrated web engine or QML, can be leveraged to go beyond C++. While at it, I hope to clear up some outdated misconceptions about Qt and its relationship to standard C++ and the STL as well as Boost and other libraries.
Finally, I will present the KDE Frameworks, an open source collection of high quality, cross platform Qt libraries that are being used by the KDE Software Collection. KDE frameworks are to Qt as Boost is to the STL. Recent development makes it simpler than ever to use these libraries in external applications.

Doxygen to DoxyPress: A Journey from C++98 to C++11
by Barbara Geller & Ansel Sermersheim
Summary of the talk:
This presentation will discuss the benefits of using a documentation generator for creating internal code documentation or end user documentation. DoxyPress can be used to document your source code, generate API documentation, show class hierarchies, collaboration diagrams, and much more. DoxyPress supports several output formats including html, chm, latex, and man pages.
As part of our talk we will cover the process of redesigning source code originally designed for C++98 and how to migrate it to C++11. We will talk about the advantages and drawbacks of moving to C++11 and show how the code changed in DoxyPress.
We will show a small demonstration of DoxyPressApp, which is a a GUI program used to set up your project file which is then used by DoxyPress to generate documentation.
DoxyPress is a fork of the Doxygen documentation tool. A very basic understanding of C++ will be helpful. No prior knowledge of DoxyPress or Doxygen is required.

The new Qt has arrived!
Qt 5.7 released
by Lars Knoll
From the article:
I’m very happy to announce that Qt 5.7 is now available. It’s been only 3 months since we released Qt 5.6, so one might expect a rather small release with Qt 5.7. But apart from the usual bug fixes and performance improvements, we have managed to add a whole bunch of new things to this release.

Haskell Design Patterns for Genericity & Asynchronous Behavior
by Sherri Shulman
Summary of the talk:
The paper explores some of Haskell's support for genericity through type classes, Functors, Monads, and Continuations and their impact on lanugages such as C++, Scala, and Rust. We explore these language features and consider alternatives that have been proposed to existing language features, including Object Algebras, GADTs, Open data types, open pattern matching, and extensions to Haskell's type system that impact the type inference algorithm and decidability. We use a number of case studies to demonstrate what proposed solutions look like in the target languages, considering how easy they are to use and how well the solutions integrate with existing linguistic features.

Do you know Conan?
What it does:
Conan is a portable package manager, intended for C and C++ developers, but it is able to manage builds from source, dependencies, and precompiled binaries for any language.

The new GoingNative is out!
GoingNative 50: New Visual C++ Code Optimizer
by Eric Battalio, Steve Carroll and Augustin Popa
From the video:
Happy 50th episode! This episode covers our new, more advanced code optimizer for the Visual C++ compiler back-end. It provides many improvements for both code size and performance, bringing the optimizer to a new standard of quality expected from a modern native compiler.
This is the first public release and we are encouraging people to try it and provide suggestions and feedback about potential bugs. The official release of the new optimizer is expected to be Visual Studio Update 3, while the release available today is unsupported and mostly for testing purposes.
Read our blog post to get the details!
