3. Catch

   2 62 20,449 9.0 C++

   A modern, C++-native, test framework for unit-tests, TDD and BDD - using C++14, C++17 and later (C++11 support is in v2.x branch, and C++03 on the Catch1.x branch)

   

   The code uses catch2 to test for correctness and performance. Catch2 is a unit testing framework for C++, but it also provides basic micro-benchmarking features. Unfortunately, it doesn't provide any way to visualise the results, so I created a script and submitted PR adding plotting capabilities to Catch.

4. range-v3

   3 20 4,356 5.0 C++

   Range library for C++14/17/20, basis for C++20's std::ranges

   

   rangesv3 - Uses ranges-v3 - range library for C++14/17/20. Pretty close to the implementation using std::ranges, but a bit more complex, because it distinguishes between actions and views. This method uses the reverse action with views and to_vector, which might allocate an extra vector.

5. flux

   4 8 743 6.3 C++

   A C++20 library for sequence-orientated programming (by tcbrindle)

   

   fluxranges - Uses flux, a C++20 library for sequence-oriented programming. Quite noisy compared to other range implementations.

   I will then convert the stats file with a perf-stat-to-sc script I wrote. It will create a sc-im spreadsheet, which will make it easier to compare the results.
