About code. Mostly on C++
Starting with C++20, some very useful functions for searching have been added to some standard containers, such as std::map, std::set, and std::string. These have been required for a long time and it’s good to see that the committee finally agreed upon their value. I hope this is the beginning of some wonderful additions.
A couple years ago I wrote a post called A better date and time C++ library about Howard Hinnant’s date library (I actually planned for several posts, but only the first was materialized). A slightly modified version of the library has been voted in for C++ 20 at the ISO committee meeting in Jacksonville this month. You can find the actual proposal here D0355R7: Extending <chrono> to Calendars and Time Zones.
In my previous post I introduced cpplinq, a C++ template library that provides .NET-like query operators for sequences of objects in C++11. In this second installment I will discuss about two things: range generators and range conversion operators. These two sets of operators are ubiquitous in queries. Range generators A range generator builds an object…
