### >>542 動くこた動くがもうわけわからんので煮詰めるのギブアップ
### Date#calenderのwideはtrueだと>>543のように表示、falseだとcalコマンドのように表示
#!/usr/bin/ruby
require 'date'
class Date
def to_a
a=Array.new; Date.new(self.year,self.month,1).upto(Date.new(self.year,self.month,-1)){|d| a.push(d)}; return a
end
def calender(wide=true)
wide ? width=3 : width=2
arr = self.to_a
cal = "#{MONTHNAMES[self.month]} #{self.year if wide}".center((width+1)*7) << "\n"
cal << ABBR_DAYNAMES.inject(''){|days,name| days << (wide ? name.rjust(width) : name.chop.rjust(width)) << ' '} << "\n"
cal << ' '*(width+1)*arr[0].wday
arr.each do |d|
cal << d.day.to_s.rjust(width) << ' '
cal << "\n" if d.wday == 6
end
return cal
end
