ruby-wmi

What is it?

ruby-wmi is an ActiveRecord style interface for Microsoft's Windows Management Instrumentation provider.

Many of the methods in WMI::Base are borrowed directly, or with some modification from ActiveRecord.

The major tool in this library is the #find method. For more information, see WMI::Base.

There is also a WMI.sublasses method included for reflection.

How do I install it?

• gem install ruby-wmi
