Question 1

How to sort by a member variable using cpp-sort?

Accepted Answer

Use projections: pass a pointer to the member as a projection parameter, e.g., `cppsort::pdq_sorter(vec, &MyClass::value);`. This sorts directly without extra copies or custom comparators.

Question 2

What's the best cpp-sort algorithm for nearly sorted data?

Accepted Answer

Use adaptive sorters like drop_merge_adapter or split_adapter wrapped around a base sorter; they optimize based on disorder, as shown in the benchmark graph where heap_sort adapted with drop_merge_adapter performs well with inversions.

Question 3

cpp-sort vs std::sort: when to choose which?

Accepted Answer

Use std::sort for general-purpose sorting where simplicity is key; choose cpp-sort when you need specific algorithms (e.g., stable sorts), projections, or adaptive behavior that std::sort doesn't offer.

Question 4

Does cpp-sort support parallel or concurrent sorting?

Accepted Answer

No, cpp-sort focuses on single-threaded algorithms; for parallel sorting, you'd need to look at other libraries or implement custom threading, as it's not a built-in feature.

Question 5

How to reduce compile times with cpp-sort in a large project?

Accepted Answer

Include only necessary sorter headers, use forward declarations where possible, and leverage precompiled headers. Since it's header-only, careful management is essential to avoid bloat.

Question 6

Can cpp-sort handle sorting networks for small arrays?

Accepted Answer

Yes, it provides sorting_network_sorter for fixed-size collections, optimized via networks from external sources, making it efficient for tiny arrays without runtime overhead.
