Hi John
Yes, we need the mimetypes.xml file as well (thanks Tomeu I forgot the
USB flash drive use case). I have tested the attached mimetypes.xml. It
is working fine. Put it in the activity directory.
Furthermore we have to change the scratch-activity script, so the
parameter with the scratch project object-id gets converted
(copy-from-journal) in a file and passed on to scratch. See the attached
scratch-activity script. I am not an expert with bash scripts, so please
give feedback.
I would like to extend the script so project files in the journal
directory are copied back to the journal after exiting scratch, but for
opening project it should work fine.
Best regards,
Philipp

Hi, Phillip.
Thanks for all your hard work in tracking this down. I had looked at
several other packages, including EToys, and couldn't figure out from
them how to do this.
I will make these changes to the next XO Scratch bundle.
Is that all I need to do? What about the mime types XML file similar to
the one added by Etoys? Does that turn out to be unnecessary?

So what would the Scratch activity have to do so files put into the
Journal
(maybe by downloading) are displayed using a Scratch icon rather
than the
generic document icon?
Shipping a mimetypes.xml file inside the bundle as explained here:
http://wiki.laptop.org/go/Activity_bundles#Bundle_Structure
Sugar will call update-mime-database and will merge that file into the
xdg mime database.
I think that John is already trying this.
Guess I'm confused then - I thought that's exactly what Philipp had
done.
I think he just changed the mime_types field in the .info file.
And I just checked and it does work with Etoys projects. When
downloading
one it indeed gets an etoys icon (although at a smaller size - why
is that?)
No idea, though I think that the mime database is updated in the etoys
rpm and not in the bundle, am I right?

Thanks Tomeu to lead me to the /home/olpc/.local directory. However, the
mimetypes.xml is not necessary to get the icon in the journal. I just
had to copy the scratch icon file in the activity directory to
"application-x-scratch-project.svg" (also in the scratch activity
dirctory). The Memorize Activity is a good example for using that
feature.
Sugar has to be restarted after installing Scratch to show the icon.
John, could you please make the following changes in the next Scratch
version:
- add the line "mime_types = application/x-scratch-project" to the
activity.info file
- copy the scratch icon to "application-x-scratch-project.svg" in the
activity directory
Etoys gets configured by different packages. e.g. the rpm
etoys-3.0.2153-1.noarch is adding the file
/usr/share/mime/packges/etoys.xml and the rpm
sugar-artwork-0.82.3-1.olpc3 is
adding the file
/usr/share/icons/sugar/scalable/mimetypes/application-x-squake-project.svg.

Philipp
