    Win32 Registry

    win32/registry is registry accessor library for Win32 platform. It uses importer to call Win32 Registry APIs.

    example
    Win32::Registry::HKEY_CURRENT_USER.open('SOFTWARE\foo') do |reg|
      value = reg['foo']                               # read a value
      value = reg['foo', Win32::Registry::REG_SZ]      # read a value with type
      type, value = reg.read('foo')                    # read a value
      reg['foo'] = 'bar'                               # write a value
      reg['foo', Win32::Registry::REG_SZ] = 'bar'      # write a value with type
      reg.write('foo', Win32::Registry::REG_SZ, 'bar') # write a value
    
      reg.each_value { |name, type, data| ... }        # Enumerate values
      reg.each_key { |key, wtime| ... }                # Enumerate subkeys
    
      reg.delete_value(name)                         # Delete a value
      reg.delete_key(name)                           # Delete a subkey
      reg.delete_key(name, true)                     # Delete a subkey recursively
    end
