CppCon 2015 Reflection Techniques in C++--Paul Fultz II

By Adrien Hamelin | Aug 10, 2016 01:11 PM | Tags: community boost

Have you registered for CppCon 2016 in September? Don’t delay – Registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2015 for you to enjoy. Here is today’s feature:

Reflection Techniques in C++

by Paul Fultz II

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Reflection is a very powerful and useful feature used in many languages to achieve things like serialization, object-relationship mapping, and general data-driven development. C++ doesn't support reflection natively in the language yet. There are proposals to add compile-time reflection to the language, but C++ has survived all this time without direct support for reflection.

This talk will discuss the various techniques the can be used to achieve reflection including boost fusion, the visitor patter, and do-it-yourself with some macros and metaprogramming. This talk will discuss how these techniques can be used to implement serialization or object-relational mapping.

An update on the Meeting C++ Workshop Day

I finally can announce that the workshops will end with talks by James McNellis and Michael Caisse:

An Update on the workshop day

by Jens Weller

From the article:

Michael Caisse - boost.fusion: power to the tuples

    Tuples provide heterogeneous, compile-time containers; however, they can be difficult to use at run-time. Boost.Fusion brings together compile-time and run-time semantics to produce the STL of the meta-programming world. It is the machinery behind several Boost libraries and is a common element in many of the solutions provided by Ciere Consulting.


James McNellis - Practical C++ Coroutines

    One of the most interesting new features being proposed for C++ standardization is coroutines, formerly known as “resumable functions”. C++ coroutines are designed to be highly scalable, highly efficient (no overhead), and highly extensible, while still interacting seamlessly with the rest of the C++ language.

CppCon 2015 Integrating generators EDSL's for Spirit X3 (WIP)--Feliple Magno de Almeida

Integrating generators EDSL's for Spirit X3 (WIP)

by Feliple Magno de Almeida

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Based on the presentation I made on C++Now 2015 for Developing EDSL's for Boost.Spirit V2, present the development of generators for Boost.Spirit X3 (next version of boost spirit) and how that can be used for higher abstraction EDSL's while, through template metaprogramming, create parsers and generators automatically from the same grammar, using CORBA format as an example, while dealing with endianness, alignment and asymmetric grammars. This work is based on the library mORBid (https://github.com/expertisesolutions...) and (https://github.com/expertisesolutions...).

Meeting C++ 2016: closing keynote & full schedule

With the announcement of the closing keynote the full schedule for Meeting C++ 2016 stands!

Closing keynote & full schedule of Meeting C++ 2016

by Jens Weller

From the article:

Since mid of June the program of the 5th Meeting C++ conference was taking shape. With the selection of the talks it was also clear in which tracks they go, so that the schedule it self was almost ready, except a last detail: the closing keynote.

The closing keynote will be held by Louis Dionne on "C++ metaprogramming: evolution and future directions".

boost 1.61.0 released

By Felix Petriconi | May 13, 2016 06:48 AM | Tags: boost

The boost community has released their library in version 1.61.0.

boost 1.61.0 released

by the boost organization

From the release note:

Beside many bug fixes and enhancements in the existing libraries, these new libraries were added:

New Libraries

Compute:
Parallel/GPU-computing library


DLL:
Library for comfortable work with DLL and DSO. Library provides a portable across platforms way to:

  • load libraries
  • import any native functions and variables
  • make alias names for C++ mangled functions and symbols
  • query libraries for sections and exported symbols
  • self loading and self querying
  • getting program and module location by exported symbol

Hana:
A modern C++ metaprogramming library. It provides high level algorithms to manipulate heterogeneous sequences, allows writing type-level computations with a natural syntax, provides tools to introspect user-defined types and much more.

Metaparse:
A library for generating compile time parsers parsing embedded DSL code as part of the C++ compilation process. The library is similar to Spirit, however while parsers built with Spirit parse at run-time, parsers built with Metaparse parse at compile-time.

Modern generic programming using the Tick and Fit libraries

By pfultz2 | Mar 18, 2016 10:25 AM | Tags: boost advanced

Paul Fultz II talked at C++Now 2015 about generic programming.

Modern generic programming using the Tick and Fit libraries

By Paul Fultz II

From the abstract:

C++ templates provide a very powerful abstraction for generic programming. Even so, they still suffer from long and confusing compile errors and this puts an extra burden of complexity on library writers who want to provide flexibility in their interfaces. In this talk, we will first discuss the importance of concept-based type requirements in code in order to produce clear compile errors, and how the Tick library can be used to specify and check those type requirements.

Later, we will discuss how the Fit library can further enhance generic programming. The Fit library provides many abstractions over functions including a way to do sophisticated overloading in a simple and concise manner. We will discuss in this talk how we can leverage these abstractions with overloading to provide simple and flexible interfaces. We will also look at comparison of these solutions with the Concepts Lite proposal and Boost.ConceptCheck.

Selecting by interface, an idea almost to good to be true

I had an idea last night...

Selecting by interface, an idea almost to good to be true

by Jens Weller

From the article:

Last night, I've been coding until 3 am. Working on an API which will connect my CMS to JSON libraries in a generic way. For this I did study different JSON Libraries in the past weeks. I almost wrote another one wink Yet, I had the idea to write a generic interface to interface with some of these libraries, so that my own code is not hard wired to a certain API...
