Re: Java & Scratch on XO
Hi, Bert and Tomeu. Many thanks for the pointers and examples. I've put together a mimetypes.xml file and will test it when I get home. (I don't have my XO with me.) I will let you know if I have any problems or questions.

True, have talked with Bert and he said that the etoys.xml file they have in the source repository is for the rpm, not for the .xo. So sorry for the misleading pointer. The idea is that your scratch bundle would have a file named mimetypes.xml in the activity dir (so next to the activity.info file, the icon, etc) and the contents would be analogous to those in etoys.xml. As you can see, that file relates extensions to mime types. Unfortunately, cannot find now an activity that currently uses it, but ping me again if you have trouble putting that to work and I will look harder or do a small experiment here.

I got a question from a professor at U. of Wisconsin about how to work with Scratch projects downloaded from the Scratch website (see below).

Re: Java & Scratch on XO
Hi, Tomeu. Thanks for your reply. It's great that there is a way to handle this! I took a quick look at the EToys .xo bundle and did not see a mimetypes.xml file. However, I did notice that EToys lists a lot of mime types in it's activity.info. What I don't see is how the system would know what file extension to associate with a type like "application/x-squeak-project". Is that what the mimetypes.xml is for? Do you know of any other activity that uses a mimetypes.xml file that would be a good model for Scratch? -- John On Dec 1, 2008, at 7:44 AM, Tomeu Vizoso wrote: > On Tue, Nov 25, 2008 at 5:01 PM, <[EMAIL PROTECTED]> wrote: >> i'm forwarding this note from john maloney (scratch maintainer) to >> devel. >> >> this certainly sounds like a mime types issue, but i'm not sure >> where or how we'd augment the canonical list. > > Paul is right, Sugar is not being able to recognize those as being > scratch files.

i'm forwarding this note from john maloney (scratch maintainer) to devel. this certainly sounds like a mime types issue, but i'm not sure where or how we'd augment the canonical list. paul john wrote: > Hi, Paul, Cynthia, and Claudia. > > I got a question from a professor at U. of Wisconsin about how to work > with Scratch projects downloaded from the Scratch website (see below). > > I verified that the problem is that the .sb file gets renamed to be > something in /tmp ending in .bin.
