String Proxy Puzzle -- Alex Marmer

C-style string cannot be used as a template parameter (X<"abc">() won't compile).

String Proxy​ Puzzle

by Alex Marmer

From the article

The puzzle is about how for any C-style string to use it's proxy as a template parameter and how to reconstruct the compile-time string from it.




C++ On Sea: Full schedule now available

The schedule for the new C++ On Sea conference is now available:

Full schedule now available

by C++ On Sea

From the announcement:

We're thrilled to announce that the full schedule for the conference has now been finalised and published. Of course, when I say, "finalised", that doesn't mean it definitely won't change again, but I don't expect much movement.

You'll notice that day two (Tuesday) has four tracks. As mentioned before, the response was so great that we felt we had to put on an extra track. Note, also, the Lightning Talks at the end of day one. We'll take submissions for that closer to the time of the conference - or at the conference.

Five Awesome C++ Papers for San Diego--Bartlomiej Filipek

What do you think?

Five Awesome C++ Papers for San Diego

By Bartlomiej Filipek

From the article:

In two weeks there will be a next C++ Committee meeting. This time the group of C++ experts will travel to San Diego, and they will discuss the shape of the upcoming C++ Standards. As far as I know, the meeting will hold a record in the number of submissions (276 proposals!) So it seems that the session will be quite exhausting smile

Here’s my list of five exciting papers that will be discussed during the meeting. I tried to pick something less popular, and usually smaller than significant features like modules, concepts or ranges...

Exploring Clang Tooling Part 2: Examining the Clang AST with clang-query--Stephen Kelly

The series continue.

Exploring Clang Tooling Part 2: Examining the Clang AST with clang-query

by Stephen Kelly

From the article:

In the last post, we created a new clang-tidy check following documented steps and encountered the first limitation in our own knowledge – how can we change both declarations and expressions such as function calls?

In order to create an effective refactoring tool, we need to understand the code generated by the create_new_check.py script and learn how to extend it.

Exploring Clang Tooling Part 1: Extending Clang-Tidy--Stephen Kelly

A very useful tool.

Exploring Clang Tooling Part 1: Extending Clang-Tidy

by Stephen Kelly

From the article:

This post is part of a three-part series about using the Clang AST Matchers to mechanically refactor C++ code. In the last post, we ensured that the code is at least buildable with Clang. While that part was only interesting to those whose code was not yet building with Clang, the rest of the series appeals to a general C++ audience.

There are many other resources on the internet covering use of existing clang-tidy checks and their motivation, such as my previous employer. There is very little information online about the developer workflow and tools to use when creating custom extensions for source to source transformations with clang-tidy. This blog series aims to fill that gap.
