# DateTime::Format ![Build Status](https://github.com/raku-community-modules/DateTime-Format/workflows/CI/badge.svg) [![Actions Status](https://github.com/raku-community-modules/DateTime-Format/workflows/test/badge.svg)](https://github.com/raku-community-modules/DateTime-Format/actions) ## Description Provides strftime(), strptime() (coming soon), and a few predetermined formats for use with both. It also comes with some localizations for month and day names. ## Convenience subroutines These are exported by ```use DateTime::Format``` ## strftime (Str $format, DateTime $dt, :$lang, :$subseconds) Format the DateTime object using the format as specified in the string. If you don't specify the language, it uses the currently set default. If you want to specify the use of subseconds in the time display, set the subseconds argument to the precision you wish to use in significant digits. Setting subseconds to 'True' would be equivalent of using a subseconds value of 1. For example: using a subseconds value of 3 would format 33.3145692 seconds as 33.315 ## strptime (Str $timestamp, Str $format, :$lang) Parse the string using the format as specified in the second string. If you don't specify the language, it uses the currently set default. ## set-datetime-format-lang (Str $code) Set the default language to use. This can be 'en' (the default language), or any language you have added using one of the Localization libraries. ## Formats ### DateTime::Format::RFC2822 Parse or Stringify a DateTime in the RFC 2822 format. ```raku my $ts = 'Tue, 30 Apr 2013 13:02:10 -0700'; my $rfc = DateTime::Format::RFC2822.new(); my $dt = $rfc.parse($ts); my $dt2 = $dt.utc(); say ~$dt2; ## Tue, 30 Apr 2013 20:02:10 +0000 ``` ## Localizations The default localization is English, using the code 'en'. There is no loadable module for English, since it's strings are included by default in the DateTime::Format module. The following are additional libraries that can add localizations to the DateTime::Format library. The languages will then be immediately usable. * DateTime::Format::Lang::FR -- French ```raku use DateTime::Format::Lang::FR; set-datetime-lang('fr'); ## You can also specify the :lang<fr> parameter to the ## strftime(), strptime() subroutines, or the parse() and format() ## methods within a DateTime::Format::* subclass such as RFC2822. ## This overrides the language for a single call, rather than setting ## a default value. ``` ## TODO * Add strptime(). * More bundled formats. * More localizations, and tests for them. ## Authors * [Timothy Totten](https://github.com/supernovus/) * [Carl Mäsak](https://github.com/masak/) * [Kodi Arfer](https://github.com/Kodiologist/) * [Clifton Wood](https://github.com/Xliff/) Anyone missing that may have contributed, feel free to create an issue to add you to the credits.
