Braden's Q2 2024 Update

Jul 14, 2024

Speaking at C++Now

At C++Now 2024, I gave my first full-length conference talk, titled “Unit testing an expression template library in C++20”. The slides are up at this link. As of the time of writing, the talk has not yet been uploaded to YouTube.

In this talk, I explored the current state of compile-time unit testing in C++ in the well-known unit testing libraries. I also discussed my own methods for unit testing at compile-time. This talk especially focuses on giving helpful diagnostics when encountering an error at compile-time. I used my tok3n library (a personal project) as a backdrop for the testing, which has been the driving force behind exploring this area in the first place.

I had an enjoyable time preparing and giving this talk, and I certainly learned a lot. I appreciate the support from the others at the C++ Alliance, for helping me to grow as a speaker and to have this amazing opportunity to speak at C++Now 2024.

Boost.Unordered Visual Studio Natvis support

In Q2 2024, I created the “boost_unordered.natvis” file, to give user-friendly visualizations for all Boost.Unordered containers in the Visual Studio debugger. In doing this, I learned quite a lot about Natvis files, which I wrote about in this article, titled “Natvis for boost::unordered_map, and how to use elements".

Unfortunately, I wasn’t initially able to support all Boost.Unordered containers. I thought I had to exclude the containers with allocators that use fancy pointers (like boost::interprocess::offset_ptr), but I consulted with Joaquín to eventually find a solution. It didn’t technically make it for Q2, but it’s close enough. I wrote a 2nd article explaining this whole process.

I am excited to continue improving the user experience for Boost.Unordered. Next up, I’ll be tackling GDB pretty-printers for the containers.
