Re: [Sugar-devel] Keep offline for Browse (offline bookmarks)
For youtube alone, I recommend one of the Youtube download scripts/extensions. There's even some userscripts and bookmarklets out there (both features I would like to add to Browse at some point). This particular patch is very much geared towards taking pure html content offline, content from plugins (such as Flash player or Java applets) may or may not work with this, depending on the website. 2009/11/10 Caroline Meeks carol...@solutiongrove.com: On Mon, Nov 9, 2009 at 5:16 PM, Lucian Branescu lucian.brane...@gmail.com wrote: This patch won't save video, at least not flash video.

Re: [Sugar-devel] Keep offline for Browse (offline bookmarks)
I've tried jar:, but there were numerous issues with navigating to other pages. Also, it was quite hard to get Browse to actually open that URI, it kept trying to prettify it. On top of that, jar: has been deprecated because of security issues. After investigating jar: I found out that it actually unzips things in temporary storage anyway. So I could easily replace jar: with two lines of code and not bother with its problems. The only thing my code doesn't do that jar: does is very prompt cleanup. 2009/11/10 S Page skierp...@gmail.com: On Sun, Nov 8, 2009 at 7:17 AM, Lucian Branescu Besides being able to save pages for offline use, this patch will also allow distribution of HTML content in .zip files that have an 'index.html' inside.

Re: [Sugar-devel] Keep offline for Browse (offline bookmarks)
I've actually implemented the full-blown web app part (it's called Site Specific Browser) for Browse as part of GSoC. The offline bit can be done either with LocalStorage (html5, but it's been around since Firefox 2.0) or Gears. So new offline-able web apps can target html5, existing web apps already use Gears (which needs more work for Browse). The other features are more invasive so I'm trying to make individual patches for each of them. This is the first one because it's the most useful on its own and it's been requested for a long time. 2009/11/10 Martin Langhoff martin.langh...@gmail.com: On Sun, Nov 8, 2009 at 4:17 PM, Lucian Branescu lucian.brane...@gmail.com wrote: Besides being able to save pages for offline use, this patch will also Question on this track (perhaps OT)... do the HTML5 specs have something in this regard?

Re: [Sugar-devel] Keep offline for Browse (offline bookmarks)
There's no UI for this, the developer of the web app must support this themselves. GMail for example already does it. The user can create a SSB for GMail, which will appear as a separate activity and can have its own userscripts and whatnot. Also, userscripts could be used to adapt website for offline use (something like http://code.google.com/apis/gears/articles/gearsmonkey.html). Right now, developers can use Gears and follow its documentation or DOM storage (https://developer.mozilla.org/en/DOM/Storage). The Karma documentation could be of help as well. You can read more on my blog (http://honeyweb.wordpress.com/) or the wiki page (http://wiki.sugarlabs.org/Webified). 2009/11/10 Martin Langhoff martin.langh...@gmail.com: On Tue, Nov 10, 2009 at 1:36 PM, Lucian Branescu lucian.brane...@gmail.com wrote: I've actually implemented the full-blown web app part (it's called Site Specific Browser) for Browse as part of GSoC.

Sorry for any confusion, the second keep_offline.patch should be applied over the older one. 2009/11/9 Lucian Branescu lucian.brane...@gmail.com: Right now, you'd need to apply the patch to Browse yourself. I've attached an .xo bundle that should work on sugar 0.86, but I haven't tested it. Right now I add some metadata to the journal object so that it is opened by Browse by default (metadata['activity']='org.laptop.WebActivity'). I could however change it so that Browse opens any .zip file, not just files it produced itself. I've attached a patch that does that (adds the zip mime type in activity.info). 2009/11/9 Caroline Meeks solutiongr...@gmail.com: This sounds great!
