Identical regexp can or cannot run in linear time depending on your ruby binary. neither forward nor backward compatibility is guaranteed about the return value of this method. You can compile ruby with the ruby debug macro to enable debugging on some features. one example is debugging object shapes in ruby with rubyvm::shape.of(object). additionally ruby can be compiled to support the ruby debug environment variable to enable debugging on some features. an example is using ruby debug=gc stress to debug gc related issues. Formats for dates and times several ruby time related classes have instance method strftime, which returns a formatted string representing all or part of a date or time: date#strftime. datetime#strftime. time#strftime. each of these methods takes optional argument format, which has zero or more embedded format specifications (see below).

The ruby standard library is a large collection of classes and modules you can require in your code to gain additional features. below is an overview of the libraries and extensions, followed by a brief description of each. At least one ruby extension (ed25519) fails to build due to incompatibilities (?) with the core library headers on fedora 42. when trying to build the ed25519 extension that is required for kamal (and i guess rails by association) there are errors relating to bool types. Class struct: class \struct provides a convenient way to create a simple class that can store and fetch values. tt>; the first argument, a string, is the name of th. Ruby programs must be written in a us ascii compatible character set such as utf 8, iso 8859 1 etc. in such character sets if the eighth bit is set it indicates an extended character.
