making a monthly calendar...

[Mikkel Bruun]

Yes. Here is my effort anyway:

require 'date'
require 'enumerator'

def days_to_show(year, month, num_week_rows)
# returns an array of the dates in month,
# with the last days of the preceding month
# and the first days of the next month

first_of_month = Date.new(year, month, 1)
first = first_of_month - (first_of_month.wday)+1
# +1 for weeks starting on monday, remove for weeks starting on sunday
last = first + (num_week_rows * 7)
(first...last).to_a
end

days = days_to_show(2008, 3, 6)
days.each_slice(7) do |week|
print "| "
week.each{|day| print day.to_s + "\t| "}
puts
end

The only thing noteworthy is the range of dates, which produces an
array.

That is really an elegant solution and it works between years
also....but....

What happens when you run ays = days_to_show(2008, 6, 6) ??? it shows
june as starting on sunday 2 of june....

really wierd

That is weird! Not only that, but for (2008, 6, 1), it gives me a
month of 2 weeks, the second having only 2 days.

Never mind that. It's just 1 week.

Argh.. Date#wday gives with a zero for sunday. But there is good luck to
be found in ruby. With Date#cwday Monday is commercial day-of-week 1;
Sunday is commercial day-of-week 7. Fine by me.


require 'date'
require 'enumerator'

def days_to_show(year, month, num_week_rows = 6)
# returns an array of the dates in month,
# with the last days of the preceding month
# and the first days of the next mont

first_of_month = Date.new(year, month, 1)
first = first_of_month - first_of_month.cwday + 1
# +1 for weeks starting on monday, remove for weeks starting on sunday
last = first + num_week_rows * 7
(first...last).to_a
end

1.upto(12) do |month|
days = days_to_show(2008,month)
days.each_slice(7) do |week|
week.each{|day| print "| " + day.mday.to_s + "\t"}
puts "|"
end
puts
end


Behaves better.
