Provides a number of methods for displaying and dealing with dates and times
Parts were strongly based on ar-code.svn.engineyard.com/plugins/relative_time_helpers/, and active_support
The key methods are `relative_date`, `relative_date_span`, and `relative_time_span`. This also gives you the Rails style Time DSL for working with numbers eg. 3.months.ago or 5.days.until(1.year.from_now)
# File lib/merb-helpers/date_time_helpers.rb, line 20 def self.time_class @@time_class end
format<Symbol> |
time format to use |
locale<String, Symbol> |
An optional value which can be used by localization plugins |
a string used to format time using strftime |
# File lib/merb-helpers/date_time_helpers.rb, line 30 def self.time_output(format, locale=nil) @@time_output[format] end
# File lib/merb-helpers/date_time_helpers.rb, line 180 def prettier_time(time, ampm=true, locale=nil) time.strftime("%I:%M#{" %p" if ampm}").sub(/^0/, '') end
Gives you a relative date in an attractive format
time<~to_date> |
|
locale<String, Symbol> |
An optional value which can be used by localization plugins |
Relative date |
relative_date(Time.now.utc) => "today" relative_date(5.days.ago) => "March 5th" relative_date(1.year.ago) => "March 10th, 2007"
# File lib/merb-helpers/date_time_helpers.rb, line 47 def relative_date(time, locale=nil) date = time.to_date today = DateAndTime.time_class.now.to_date if date == today DateAndTime.time_output(:today, locale) elsif date == (today - 1) DateAndTime.time_output(:yesterday, locale) elsif date == (today + 1) DateAndTime.time_output(:tomorrow, locale) else fmt = DateAndTime.time_output(:initial_format, locale).dup fmt << DateAndTime.time_output(:year_format, locale) unless date.year == today.year time.strftime_ordinalized(fmt, locale) end end
Gives you a relative date span in an attractive format

Condenses time... very similar to time_ago_in_words in ActionPack
from_time<~to_time> |

to_time<~to_time> |

include_seconds<Boolean> |
Count the seconds initially, Defaults to false |
