Workpattern Rubygem Documentation
Workpattern 
Calculates dates and durations whilst taking into account working and non-working times. It creates calendars similar to what you can find in project scheduling software like Microsoft project and Primavera P6.
Please use Github Issues to report bugs. If you have a question about the library, please use the workpattern tag on Stack Overflow. This tag is monitored by contributors.
Getting Started
Workpattern is a library with no monkey-patching and was tested using Travis against the following Ruby versions 1.9.3, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, ruby-head (3.1.0dev), jruby-19mode (9.2.9.0 (2.5.7) and jruby-head (9.3.0.0-SNAPSHOT (2.6.5).
You can install it using:
gem install workpattern
Or you can add it to your Gemfile with:
gem "workpattern"
Then run the bundle command to install it.
Use
Configure and Calculate
First create a Workpattern to hold all the working and resting times.
mywp=Workpattern.new 'My Workpattern',2011,10
That line created a Workpattern called My Workpattern starting on 1-Jan-2011 and continuing for 10 years until 2020.
mywp is created with a 24 hour a day working time. Next step is to tell it to ignore weekends by making every Saturday and Sunday non-working.
mywp.resting :days => :weekend
The Workpattern.clock method can be used to specify the non-working times for each weekday. Any class that responds to #hour and #min methods such as Time or DateTime can be used instead of Workpattern.clock.
mywp.resting :days =>:weekday, :from_time=>Workpattern.clock(0,0),:to_time=>Workpattern.clock(8,59)
mywp.resting :days =>:weekday, :from_time=>Workpattern.clock(12,0),:to_time=>Workpattern.clock(12,59)
mywp.resting :days =>:weekday, :from_time=>Workpattern.clock(18,0),:to_time=>Workpattern.clock(23,59)
As well as :weekend and :weekday it is possible to use :mon, :tue, :wed, :thu, :fri, :sat, :sun or all.
With mywp setup, the #calc method is used to add 32 hours which must be supplied as the number of whole minutes (1920) to a date.
my_date=Time.gm 2011,9,1,9,0
result_date = mywp.calc my_date,1920 # => 6/9/11@18:00
The result takes into account the non-working or resting times.
Subtracting a date is just as easy by using a negative number of minutes in #calc.
Finding the duration between two dates is also easy using the #diff method.
diff_result = mywp.diff my_date, result_date # => 1920
Vacations can be added to the Workpattern using the #resting method:
mywp.resting :days => :all, :start => DateTime.civil(2011,5,1), :finish => DateTime.civil(2011,5,7)
Find out if a specific date and time is working or not.
mydate = DateTime.civil 2011,5,2,9,10
mywp.resting? mydate # => true
mywp.working? mydate # => false
Manage
# Fetch a specific Workpattern
Workpattern.get "My Workpattern"
# Delete a specific Workpattern
Workpattern.delete "My Workpattern"
# Delete all Workpatterns
Workpattern.clear
