The win32-taskscheduler library is a Ruby interface to the MS Windows Task Scheduler. It is analogous to the Unix cron daemon.
gem install win32-taskscheduler
require 'win32/taskscheduler'
include Win32
ts = TaskScheduler.new
# Create a trigger that starts on April 25, 2014 at 11:05 pm. The trigger
# will run on the first and last week of the month, on Monday and Friday,
# in the months of April and May.
#
trigger = {
:start_year => 2014,
:start_month => 4,
:start_day => 25,
:start_hour => 23,
:start_minute => 5,
:trigger_type => TaskScheduler::MONTHLYDOW,
:type => {
:weeks => TaskScheduler::FIRST_WEEK | TaskScheduler::LAST_WEEK,
:days_of_week => TaskScheduler::MONDAY | TaskScheduler::FRIDAY,
:months => TaskScheduler::APRIL | TaskScheduler::MAY
}
}
ts.new_work_item('my_notepad', trigger)
ts.application_name = 'notepad.exe'
ts.activate('my_notepad')If you installed this library as a gem then the documentation was built for you and can be viewed if your gem server is running. There is also some documentation on the github wiki page.
This library was modeled to some degree on the Win32::TaskScheduler Perl module by Umberto Nicoletti. However, there are some differences. Please see the documentation for details.

Some versions of Ruby have been known to segfault when attempting to create a task. If this happens you will need to upgrade your version of Ruby. Or, at least, your version of win32ole.
In some cases JRuby appears to raise a native exception rather than a Ruby exception on failure. This should be mostly harmless.
