[Bert Freudenberg <bert@xxxxxxxxxxxxxxx>]

I worked on a new version over the weekend. This one seems to do the trick :)

I decided to make a full XO bundle for testing this time:

http://dev.laptop.org/~bert/scratch/Scratch-20100308.xo

That's because there are a few new files, like project/sprite SVG icons, mimetypes.xml, the scratch-wrapper script was scrapped etc.

Most significantly, resuming from the Journal (or Home screen in newer Sugar) works now. It may not always resume a project you saved in my last version, but loading those and resaving should fix the metadata.

"Save" always overwrites the previous Journal entry, "Save as" always creates a new one.

Metadata is preserved, that is, if you added a tag in the Journal it should still be there after re-saving. Same for the description - this is kept separate from the project's comment you see inside Scratch because I could not figure out which one should win if they differ.

The metadata contains the full project summary, so if you search e.g. for a sprite name in the Journal, projects containing it are found. If John fixes the PNG generator we can also have thumbnails in the Journal. Otherwise I consider this to be pretty much complete :)

Please report back with any problems you find. Everything Journal-related should work now.

In 0.82 each USB drive appeared as different "mountpoint" in the datastore, they could be enumerated and the Journal queries could be filtered by mountpoint. Unfortunately, no filtering is done by default, so if you mount a USB drive on an XO-1, the USB files will show up even when you click Scratch's Journal button.

Seems like being able to import and open projects from the journal is the highest priority, so if Bert is running out of hours to work on this, perhaps save/export is something we could omit. But that's up to Claudia to decide. Note that if we had an easy way to get to the USB drive that might be a way to move data between Scratch and the Journal when necessary.

(Sorry, I was mistaken earlier when I said I saw the project name in the journal.) Bert, it's a bit more work, but you could extract the project's name from the project history (the last "share" entry).
