C++ Papers for Issaquah - Concepts, Database and Evolution

By Meeting C++ | Feb 6, 2014 04:33 PM | Tags: standardization issaquah intermediate experimental evolution database concepts advanced

This is the second part of my series about the papers for the next C++ committee meeting in Issaquah:

C++ Papers for Issaquah - Concepts, Database & Evolution

by Jens Weller

From the article:

This is the second part about the papers for the C++ committee meeting in February in Issaquah. This time featuring papers from the subgroups of concept, database and evolution. Again, most papers in this series aim for a standard after C++14, most important for C++14 will be the national comments on the new standard. Also there are no new papers from the core working group, only the active issues, defects report and closed issues report are on this mailing.

 

C++ Papers for Issaquah -- Concurrency

By Meeting C++ | Jan 29, 2014 07:47 AM | Tags: standardization performance intermediate experimental concurrency c++14 advanced

So I just started to read through the papers for the next C++ committee meeting in Issaquah in February, first part is about Concurrency:

C++ Papers for Issaquah -- Concurrency

by Jens Weller

From the article:

In february the C++ committee is going to meet for a week in Issaquah, it could be the final Meeting for C++14, the papers in this series will reflect both, C++14 and the standard that will come after it. Currently mostly known as C++1y. A lot of papers that are not part of C++14 will be formed into technical specifications, which some will then become C++1y later. Like the last series, I will again focus on the working groups, and post the papers sorted by the name of the working group, starting with concurrency.

C++11 and Boost

By Meeting C++ | Oct 17, 2013 10:11 AM | Tags: intermediate experimental c++11 boost advanced

What issues arise when combining C++11 and (older) Boost code that has pre-standard versions of C++11 features?

C++11 and Boost

by Jens Weller

From the article:

Some parts of the Standard Library in C++11 are predated in boost. When playing around with C++11, you get used to using some parts in the Standard Library that are used in C++03 with their boost counterpart. Also, there is some libraries now occuring, which are C++11 based, so interfacing with either boost or C++11 code is soon an issue.

The start of my series about the papers for the upcoming Chicago meeting, starting with C for Concurrency:

C++ Papers for Chicago: Part 1 -- Concurrency

From the article:

As I did write a series about the papers for Bristol, this is the start of the series for Chicago, as at the end of this month the C++ committee will meet again for standardization. I try to...

Revisiting the BlackBerry 10 NDK

I've been looking at the BlackBerry 10 NDK the last weeks, and did write about it to share some thoughts and results.

Revisiting the BlackBerry 10 NDK

From the article:

The last few weeks I did look again at the BlackBerry 10 NDK, as a client had asked for help and training. I offered to adapt my Qt Introduction course to the BlackBerry plattform, and offered my advice...

Before I start, a short paragraph about Apps and C++. People coming from Java or .NET often don't understand the need to make Apps in C++...

Resumable Functions: async and await -- Jens Weller

JensWeller_small-da9313ea.jpgA look at resumable functions:

Resumable Functions: async and await

by Jens Weller

From the article:

While I did my series about the papers for Bristol, there was one paper, which I personally found a bit weird. This paper was about resumable functions, and at that time it was just another paper full of ideas for C++ to me. At C++Now suddenly, I got a better insight to what the use of resumable functions could be...

New paper: N3703, Extending std::search to use Additional Searching Algorithms (v3) -- Marshall Clow

By Blog Staff | Jul 2, 2013 10:05 AM | Tags: experimental

Note: This paper explores potential future standardization directions and alternatives. It does not discuss or propose to amend the C++14 Committee Draft paper whose ballot is currently in progress.

 

A new WG21 paper is available. A copy is linked below, and the paper will also appear in the next normal WG21 mailing. If you are not a committee member, please use the comments section below or the std-proposals forum for public discussion.

Document number: N3703

Extending std::search to use Additional Searching Algorithms (Version 3)

by Marshall Clow

Excerpt:

Note:

  • This is an update of n3606, presented in Portland. The major differences are support for comparison predicates in Boyer-Moore and Boyer-Moore-Horspool, and wording for the standard.
  • n3606 was an update of n3411, presented in Portland. The major difference is a different interface for the search functions.

[...]

std::search is a powerful tool for searching sequences, but there are lots of other search algorithms in the literature. For specialized tasks, some of them perform significantly better than std::search. In general, they do this by precomputing statistics about the pattern to be searched for, betting that this time can be made up during the search.

The basic principle is to break the search operation into two parts; the first part creates a "search object", which is specific to the pattern being searched for, and then the search object is passed, along with the data being searched, to std::search.

This is done by adding an additional overload to std::search, and some additional functions to create the search objects. ...
