register thumbnailer in gnome config

[Aegluin]

Hi!
I try to implement thumbnails for files from a Wine program in order to integrate it better in Ubuntu. The Program is Sketchup which creates *.skp files in a binary format, but I found a ruby script that can extract the thumbnail (*.png).

Now I wanted to register it in the gnome configuration according to the following instruction:
http://library.gnome.org/devel/integumbnailer.html

It works perfect if I execute the script manually (package ruby installed, script is executable):


ruby ~/.wine/skp-thumbnailer.rb /home/user/test.skp /home/user/test.png

Creates successfully a thumbnail test.png from the file test.skp.
With the following commands, I registered the script, but it doesn't create thumbnails automatically:


gconftool-2 -s /desktop/gnome/thumbnailers/application@wine-extension-skp/enable --type=bool true
gconftool-2 -s /desktop/gnome/thumbnailers/application@wine-extension-skp/command --type=string "ruby ~/.wine/skp-thumbnailer.rb %i %o"

Now my question is how to find the mistake. Do I need to copy the script into /usr/bin ? Apart from that, would it be possible to create it as a shell script (without ruby requirement)? If I knew how to translate it into .sh, I would prefer that.
Many thanks for help!

I am not positive of this, but I believe haven't used tho proper argument placeholders in your gconf key. If you'll look at the other thumbnailers, they all use %s %u and %o. %s is size, %u is the URI of the file to be thumbnailed, and %o is the output filename. I think you could just ignore the size argument, and generate the same size regardless what nautilus wants. But, I am not sure if that works.

In regards to making this a shell script, I think that would be possible, but it certainly won't be pretty (at least not in the manner that I might do it, but, I, myself, am much more comfortable in Ruby). Why do you want not to use a Ruby script?

Another thing I would change is the location of your script file. I would put it in either /usr/bin or ~/bin (you may need to make that folder). There is no reason for it to be mixed in with WINE. Also, it may be best to use a full path instead of the tilde abbreviation.

Finally, and here is the most important part, your Ruby script won't work if it is fed a URI, which, as I said before, is what gnome will send the thumbnailer. I can help you fix it, though, if you want.

Hi!
many thanks for the help! I solved it already some weeks ago after nobody replied.
The problem was the mime type had to be application/x-wine-extension-skp and the script must be placed in /usr/bin. I finally used a python variant of the script that I found somewhere on the internet and now it works.

Okay! Good to hear you got some help and got it fixed. Could you mark the thread as having been solved, please?
