Schedule Reminder is a console based small application that reads the events from a yaml file and displays reports based on the user's choice.
Its written in Ruby.For the beginning, prepare your schedule.yml file by using a text editor.
Sample yaml file can contain following lines in it for this program.
## YAML Template. app1: date_time : 2009-04-22 00:00 subject : Deadline for HW app2: date_time : 2009-04-23 14:00 subject : Lecture Hour app3: date_time : 2009-04-29 14:00 subject : Research app4: date_time : 2009-04-28 14:00 subject : Meeting at Office app5: date_time : 2009-04-28 14:00 subject : Meeting with friends app6: date_time : 2009-04-28 14:00 subject : Library app7: date_time : 2009-04-30 20:00 subject : Watch game
You can also download schedule.yml file from the link.
Then prepare your generateScheduleReport.rb file and create a new GenerateReport class in it.
When the user runs the program, a console based menu is displayed to the client. Until the client enters a valid input from the console it is displayed.
To find events of today following method can be implemented.
Method searches for the entry with today's time from the hash and if found puts it in an array.
def generate_report_for_the_events_of_the_day()
t = Time.now
t = t.strftime("%Y-%m-%d")
event_array, event_index, hashelement = load_yaml_from_location
for i in (0...hashelement.keys.size)
x = hashelement[hashelement.keys[i]]
str = x[x.keys[1]]
str = str[0..9]
if str.eql?(t.to_s)
event_array[event_index] = x[x.keys[0]] +" --- "+x[x.keys[1]]
event_index = event_index + 1
end
end
if event_array.size > 0
puts "Report for the events of today is:\n"
if event_array.size==1
puts "There is 1 event in your schedule for today\n"
else
puts "There are "+event_array.size.to_s
+" events in your schedule for today\n"

end
else
puts "There is no event in schedule for today\n"
end
end

puts event_array[j]+"\n"
end
else
puts "There is no event in schedule for this week\n"
end
end
To find events of the month following method can be implemented.
Method searches for the entry with this month's date from the hash and if found puts it in an array.
def generate_report_for_the_events_of_the_month()

str = str[5..6]
if str.eql?(t.to_s[5..6])
event_array[event_index] = x[x.keys[0]] +" --- "+x[x.keys[1]]
event_index = event_index + 1
end
end
if event_array.size > 0
puts "Report for the events of the month is:\n"
if event_array.size==1
puts "There is 1 event in your schedule for this month\n"
else
puts "There are "+event_array.size.to_s

To load yaml file and store its content in a hash, following method can be implemented:
def load_yaml_from_location
hashelement = {}
hashelement = YAML::load_file('/home/tufangorel/Desktop/schedule_reminder/schedule.yml')
event_array = Array.new
event_index = 0
return event_array, event_index, hashelement
end
Ruby comes with a rich date library operations.
You can download generateScheduleReport.rb file from the link.
Put this generateScheduleReport.rb and schedule.yml files into the same folder and execute following command from the console to run the application.
user@machine:~/Desktop/reminder$ ruby generateScheduleReport.rb
A welcome menu is displayed and it loops until the user enters one of the options.
Tested on ubuntu9.04
