Use the Right Arrow or Left Arrow to choose between AM and PM.Ģ. To chain some calculations with Ruby core type without extending this type, we can just "wrap" it into a monad-like object, do the calculations, and unwrap at the end (TimeMath itself, and my Hash-processing gem hm have used this approach).1.+(something), which may look unusual at first, but can be super-handy even with simple numbers, in method chaining - I am grateful to my Verbit's colleague Roman Yarovoy to pointing at that fact (or rather its usefulness) Math operators can be called just like regular methods.days is "internal name that makes sense inside the code", which we represent by Symbol in Ruby.(2, days) is just a tuple of two unrelated data elements.The thought process that led to the new library is: now, 2 ) # Ughhh what? "Day decrease now 2"? days # also there is 2.days.ago, but I am not a big fan of "1000 synonyms just for naturality" # TimeMath: TimMath. # Natural language: 2 days ago # "Formalized": now - 2 days # ActiveSupport: Time. This simplest use case (some time from now) in TimeMath looked too far from "how you pronounce it": TBH, using the library myself only eventually, I have never been too happy with it: it never felt really natural, so I constantly forgot "what should I do to calculate '2 days ago'". ![]() One of the attempts to find an alternative has led me to the creation of time_math2, which gained some (modest) popularity by presenting things this way: (time, 1). I am not completely against-any-monkey-patches kind of guy, it just doesn't sit right, to say "number has a method to produce duration". Prominent ActiveSupport's answer of extending simple numbers to respond to 1.year never felt totally right to me. The idea of this library (as well as the idea of the previous one) grew of the simple question "how do you say + 1 hour in good Ruby?" This question also leads (me) to notifying that other arithmetical operations (like rounding, or up to with step ) seem to be applicable to Time or Date values as well. While in ActiveSupport-enabled context TimeCalc may seem redundant (you'll probably use time - 1.day anyways), some of the functionality is easier with TimeCalc (rounding to different units) or just not present in ActiveSupport (time sequences, iterate with skippking) also may be helpful for third-party libraries which want to use TimeCalc underneath but don't want to be broken in Rails context. Since 0.0.4, supports ActiveSupport::TimeWithZone, too.on Ruby on Ruby 2.6+, for Time with real timezones, preserves them.Tries its best to preserve timezone/offset information:.create sequences from Date to Time, calculate their diffs) Works with Time, Date and DateTime and allows to mix them freely (e.g.Arithmetic akin to what Ruby numbers provide: +/ -, floor/ ceil/ round, enumerable sequences ( step/ to).Small, clean, pure-Ruby, idiomatic, no monkey-patching, no dependencies (except backports).See API design section to understand how and why TimeCalc is different. As I decided to change API significantly (completely, in fact) and drop a lot of "nice to have but nobody uses" features, it is a new project rather than "absolutely incompatible new version". NB: TimeCalc is a continuation of TimeMath project. TimeCalc tries to provide a way to do simple time arithmetic in a modern, readable, idiomatic, no-"magic" Ruby.
