From the article:
Part 2 of my series about the current proposals for C++17. This part is covering the Technical Specifications (TS), which are currently released. Some of them will make it into C++17. Those not making it into C++17...

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
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...

Cheerp PreExecuter: compile-time evaluation of constructors--Sander Mathijs van Veen
An advancement in the world of C++ to javascript:
Cheerp PreExecuter: compile-time evaluation of constructors
by Sander Mathijs van Veen
From the article:
The size of a JavaScript web application, especially when compiled from a complex C++ source, has a key role on the quality of the user experience, being directly connected to the download and startup time. Size also has a big impact on the traffic and bandwidth needs of the hosting server, which translates one to one into costs. Therefore, minimizing the size of JavaScript applications compiled from C++ with Cheerp has always been one of our priorities...
Notes on C++ SFINAE -- Bartlomiej Filipek
Bartlomiej explains in his recent blog post in nice details the SFINAE construct.
Notes on C++ SFINAE
by Bartlomiej Filipek
From the article:
This time I’d like to tackle a bit more complex problem: SFINAE. I’m not using this paradigm on a daily basis, but I’ve stumbled across it several times and I thought it might be worth trying to understand this topic.
What is SFINAE? Where can you use it? Do you need this on a daily basis? Let’s try to answer those questions.
In the article he goes into details of Overload Resolution, Where can I use it?, enable_if, Expression SFINAE, Any disadvantages?, and Alternatives to SFINAE.
Revisiting QWidgets & data, refactoring and performance
A follow up on an older Blog post of mine:
Revisiting QWidgets & data, refactoring and performance
by Jens Weller
From the article:
My CMS project has grown quite a bit, and there are a few places where I think I should refactor the code. One of the larger ones is that TreeItem::get<T> returns a pointer instead of a reference. Another one is related to how the Qt UI application is acting when opening a new panel in the TabControl. There used to be a noticeable delay...

Searching and replacing in strings with boost
My series on building applications with Qt an boost continues:
Searching and replacing in strings with boost
by Jens Weller
From the article:
The next big milestone for my CMS is to actually generate HTML files, and I'm almost there. I'll reach it in the next two weeks, most code is written, just a little bit of refactoring is needed. This blog post is about searching and replacing in strings. As I started last week with implementing the functionality, that turns the data in my CMS into an HTML website.
There needs to be a lot of text transformed, in order to turn a shared structure like a cross page layout into a single, special HTML file, one of those transformations is, to replace the internal links with the correct links. A link to a different page in the same website cannot be represented as a text link, instead it is represented by a linkid, which corresponds to the Page it points to. This is to have still the correct link, if the page is renamed or moved...
