NAME

DateTimeX::Format::Ago - I should have written this module "3 years ago"

SYNOPSIS

  my $then = DateTime->now->subtract(days => 3);
  say DateTimeX::Format::Ago->format_datetime($then); # "3 days ago"

DESCRIPTION

Ever wished DateTime::Format::Natural had a format_datetime method? This module provides human-friendly datetime formatting, outputting strings like "3 days ago".

Primary use case: websites that show a list of a person's recent activities.

Constructor

new(language => $lang)

Creates a formatter object for the given language (a BCP47 language code). If the language is omitted, extracts it from $ENV{LANG}.

Decent English ('en'), German ('de'), French ('fr'), Portuguese ('pt'), Korean ('ko'), and Indonesian ('id') support is provided. Castillian Spanish ('es') is also provided, but some of the strings were translated with Google Translate, so they might not be perfect.

Methods

format_datetime($dt)

Returns something like "3 days ago", "just now" or "hace un año".

parse_datetime($string)

Croaks. Don't use this.

BUGS AND LIMITATIONS

High resolution datetimes

Imagine the time is currently 2020-01-01T12:00:00.200. If you try to format the time 2020-01-01T12:00:00.100 you'll get back the result "in the future". So what's going on? DateTimeX::Format::Ago figures out when "now" is using DateTime->now, which rounds back to the nearest whole second.

If you know you're going to be dealing with high resolution datetimes, and don't want to occasionally see "in the future" for times in the very recent past, then use Time::HiRes.

 use Time::HiRes qw();

That's all you need to do. Merely loading it will give DateTimeX::Format::Ago an indication that you want it to use a more accurate idea of "now".

Translations

This module only supports a handful of languages. I'm seeking translations. Feel free to attach patches for other languages as bug reports.
