Win 32 utils changenotify

Ruby
1

I just downloaded and installed the win32utils installer. When I try to
run the sample script provide in changenotify.txt

require “win32/changenotify”
include Win32

Wait for any writes to files in the C:\ drive.

filter = ChangeNotify::LAST_WRITE
cn = ChangeNotify.new(“C:\”,true,filter)
cn.wait{ |s|
puts “Something changed”
puts "File: " + s.file_name
puts "Action: " + s.action

}

I get the following error.

:/ruby/lib/ruby/site_ruby/1.8/i386-msvcrt/win32/ipc.so: invalid
attribute name recursive?' (NameError) from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:inrequire’
from cjsample.rb:1

What am I doing wrong?

thanks,

Luis

You’ll need to upgrade to 0.4.2. You can either build from source or
download the .so file directly, rename it to “changenotify.so”, and
install it under c:\ruby\lib\ruby\1.8\i386-mswin32\win32.

The .zip file is at
http://rubyforge.org/frs/download.php/14978/win32-changenotify-0.4.2.zip
The .so file is at
http://rubyforge.org/frs/download.php/14979/changenotify-0.4.2.so

I downloaded the file and renamed it according to your instructions but
I am still getting the same error.

Whoops. Download the latest win32-ipc and build from source or install
the .so file in the same directory as before.

Source file:
http://rubyforge.org/frs/download.php/2757/win32-ipc-0.4.1.zip

Shared object:
http://rubyforge.org/frs/download.php/4586/ipc.so

I acutally found out that I had 2 copies of changenotify.so in the ruby
folder. After deleting the older one it is working.

It works but it exits after a file change. Is it possible to
continuously monitor the folder?

Sure thing:

cn.wait{ |s|
puts “Something changed”
puts "File: " + s.file_name
puts "Action: " + s.action
} while true

Thanks for the help. I am still getting the following error when a file
event occurs.

Something changed
win32change.rb:11: undefined method file_name' for #<Array:0x2cab5c8> (NoMethodError) from win32change.rb:9:inwait’
from win32change.rb:9

Try this one:

cn.wait{ |arr|
arr.each{ |info|
p info.file_name
p info.action
}
} while true

Try this one:

cn.wait{ |arr|

arr.each{ |info|

p info.file_name

p info.action

}

} while true

Regards,

that works for me.
btw, Daniel, would you know how to monitor file/dir changes in usbs? I
have no idea yet since usbs are dynamic (now you see them, now you
dont).

kind regards -botp
