dateweek.rb

require "date"
require "optparse"

 class DateWeek
	@@wday_ja = ['日','月','火','水','木','金','土']
 	def initialize
	 	@today = Date.today
		@this_monday = @today - (@today.cwday - 1)
		@this_friday = @this_monday + 4
 	end
 	def cal_this_week
		@this_monday.upto(@this_friday) do |date|
			puts '## ' + dateformat(date)
		end
 	end
 	def weekno_date
 		puts "Wk#{@this_monday.cweek}: #{dateformat(@this_monday)} - #{dateformat(@this_friday)}"
 	end

 	private

 	def dateformat(date, opt=nil)
 		retstr = sprintf("%2d/%2d (%s)" , date.mon, date.day, @@wday_ja[date.wday])
 		return retstr
 	end
 end

dw = DateWeek.new
opt = OptionParser.new


# 登録するだけ
opt.on('-w'){dw.weekno_date()}
opt.on('-c'){dw.cal_this_week()}
# parseして処理実行
opt.parse(ARGV)

• 日付の演算
• OptionParser
  • on() で処理を登録して、parse()で実行 （処理順はどうなる?）
