My only complaint is there are a couple of characters that the -F (treat as literal) option seems to still treat as a special character needing some kind of escape - though I don't remember which ones now.
Always glad to see it keep updating!
If you have an example, I can try to explain for that specific case. But `-F/--fixed-strings` will 100% turn off any regex features in the pattern and instead will be treated as a simple literal. Where you might still need escaping is if your shell requires it.
Totally love your work! We've been sponsoring for awhile even though it isn't much. Thank you for all you do!
I'd be happy to answer more specific questions.
Short opinionated summary is: nicer API, fewer footguns, more features, better support for calendar durations, integrated tzdb support and lots more to be honest.
Note that `std::time` just gives you a platform independent but bare bones access to monotonic and system clocks. Some kind of datetime library is needed if you want to do anything with Unix timestamps beyond treat them as an integer.
I think maybe a syntax like -F=-regex would work.
