Do you think that it is worth proposing an addition to Boost.Chrono that provides only stopwatches (without reporting)? It would be really nice to have a replacement for Boost.Timer ASAP. Perhaps it would make sense to introduce something simple as a Chrono example, and then decide how to expand it into a library later?
I don't know what do you consider a simple example.
Oops, I meant: yes please make stopwatches a sublibrary of chrono and then see if it needs to set off on its own. All I want is a replacement for boost::timer, for writing benchmarks. I never used the progress_timer so I don't know about the reporting side of Boost.Timer, never wanted it. I want a simple class that keeps track of elapsed time so I don't have to even do one subtraction. In one quick pass of the Stopwatches documentation, I can't find anything that doesn't do automatic reporting. I figure there must be a class in there that looks a lot like boost::timer or the one in Chrono's "key is struck" example, which is what your original question must be proposing. I find Boost.Timer kind of buggy. It was reporting CPU time on Linux, so I couldn't benchmark a parallelized program. I feel it has other problems. I thought Chrono was supposed to replace it, but it's still a little verbose for this very simple task. Cheers, Gordon
