Well, it's getting there... very slowly. Still nothing from 37
signals, does anyone have a good address to send to?
Anyway, my function is coming along. Not the prettiest, but already
farely powerful. If anyone is interested check it out and make it
better. (it uses a few things in the rails time_extensions.rb code so
run it in script/console, or include the file) I'll keep you
posted...
#TODO:
# Turn words into numbers
# Do days in the month eg. "the 22nd", "february 3rd"
# Maybe incorporate ParseDate
def time_warp period
period = period.strip.downcase
now = Time.now
#lasts & nexts eg. "last monday", "last mar", "last week" TODO
next is wonky....
if period =~ /(last|next|this)\s*(\w+)/
type = $2
rel = $1 =~ /last/ ? -1 : 1
now =
if i = Date::DAYNAMES.index(type.capitalize) then now + rel *
(now.wday - i <= 0 ? (now.wday - i) + 7 : now.wday - i).days
elsif i = Date::ABBR_DAYNAMES.index(type.capitalize) then now +
rel * (now.wday - i <= 0 ? (now.wday - i) + 7 : now.wday - i).days
elsif i = Date::MONTHNAMES.index(type.capitalize) then now + rel
* (now.month - i <= 0 ? (now.month - i) + 12 : now.month - i).months
elsif i = Date::ABBR_MONTHNAMES.index(type.capitalize) then now
+ rel * (now.month - i <= 0 ? (now.month - i) + 12 : now.month -
i).months
elsif type == "week" then now + rel * 1.week
elsif type == "month" then now + rel * 1.month
elsif type == "year" then now + rel * 1.year
else
now + rel * 1.day
end
end
#Awesome relative stuff... eg. "the week before last tuesday", "2
weeks from now"
if period =~ /(\d+|the*) (day|month|week|year)(?:s)?
((ago|before)|(from now|after))/
rel = $3; type = $2
num = $1 =~ /(\d+)/ ? $1.to_i : 1
num *= rel =~ /(ago|before)/ ? -1 : 1
now =
case type
when "day"; now + num.days
when "month"; now + num.months
when "week"; now + num.weeks
when "year"; now + num.years
else now
end
end
#relitavize
now =
case period
when /yesterday/; now.yesterday
when /tomorrow/; now.tomorrow
else
now
end
# arbitrary times
if period =~ /(morning|afternoon|evening|night|lunchtime)/
now =
case $1
when "morning"; now.change(:hour => 8)
when "afternoon"; now.change(:hour => 15)
when "evening", "night"; now.change(:hour => 20)
when "lunchtime"; now.change(:hour => 12)
else now
end
end
#at's, does PM and AM as well
if period =~ /at (\d+):*(\d*)\s*(pm)*/
hour = $1.to_i > 23 ? 23 : $1.to_i
min = $2.to_i > 59 ? 59 : $2
if $3 == "pm" then hour += 12 end
now = now.change(:hour => hour, :min => min)
end
return now
end

The ParseDate.parsdate method in the standard library does the first
three on your list, http://www.rubycentral.com/book/lib_standard.html
I want that and some more fun stuff like your other examples or "last
tuesday at 5", "four days ago in the afternoon" (maybe a little
rediculous). It's the relative stuff that gets interesting...
Does anyone know of something out there that will turn number strings
(eg. "four") into a number? It gets fun when you do stuff like
"thirteenth"...
