Access tuple-like container by type to return an index -- Krzysztof Ostrowski
How would you look for an item in a tuple by the item's type, and return the item's index within that tuple?
Access tuple-like container by type to return an index
by Krzysztof Ostrowski
From the article:
Presentation of a technique that composes an application of a lazy fold expression, and an idea of type embellishment that introduces an implicit context in which the current tuple element is embedded.
Eliminating the Static Overhead of Ranges--vector-of-bool
Very interesting.
Eliminating the Static Overhead of Ranges
by vector-of-bool
From the article:
C++20 is slated to receive Ranges, which is probably the most significant library update since the STL itself was introduced...
C/C++ Include Guidelines -- Thomas Young
Good practices for setting up include files are key to keeping large code-bases manageable, in pre-modules C++, and this article presents 15 rules to keep you on the right track.
C/C++ Include Guidelines
by Thomas Young
From the article:
The rules listed here are relatively mechanical, by which I mean that these are things that can be applied locally to individual bits of source code, without strokes of genius or flashes of inspiration, but with the possibility to nevertheless significantly improve code organisation, which is useful particularly in the case of large legacy code bases.
How to Merge Consecutive Elements in a C++ Collection--Jonathan Boccara
Simple and sweet.
How to Merge Consecutive Elements in a C++ Collection
by Jonathan Boccara
From the article:
Merging identical consecutive elements in a collection is a recurring need, in C++ or elsewhere in programming.
For example, we could want to aggregate a collection of hourly results into a collection of daily results: all the results of each day get aggregated into one for that day. In this case, being “identical” means being on the same day, and “aggregating” means taking two results with a common date, and creating a result at this date and with the sum of their amounts...

Cppcon 2019 Milestone | New Home | Trip Reports--Jon Kalb
Many things happened.
Milestone | New Home | Trip Reports
by Jon Kalb
From the article:
CppCon 2019 was the first year in our new home at the Gaylord Rockies in Aurora, Colorado.
Long before I’d ever done it, I told people that I thought that moving a conference is almost as much work as starting one from scratch. Now that I have moved a conference, I’ve learned that started a conference from scratch is actually easier than moving that conference after it has been growing in one location for five years...
