XoxoOutliner rewrite coming, now with event delegation

2006-11-06T18:14:26+00:00

For what it's worth: I've answered my own question about event delegation based drag and drop. It seems to work quite well on my machine, which is quite a bit beefier than my old machine. I should try it out on there soon. But, I'll hopefully be releasing it soon in the form of a mostly-rewritten XoxoOutliner that will feature drag and drop outline items as well as keyboard navigation/control and in-place editing. And, it should actually start to become useful, since I plan to also whip up a PHP-based server side bit that will handle loading and saving outlines, as well as possibly a client-side bit that can save outlines using local browser storage. I have the technology - we'll see how far my ambitious plans take me during this hobbling sprint of development.

Great news Les! I had checked out the souce of XoxoOutliner and was thinking about playing around myself. Let me know if you'd like an additional tester. :)

Is there a demo of the event delegation framework you are building posted?

Nope, nothing available or posted yet. Soon, though - hoping to check the works in before the end of the week. It's a bit in pieces right now

Les, very exciting that you're jumping back into the XoXoOutliner code! I can't wait to try to hook it up to HyperScope and play with it some more. It's the best open source DHTMLly outliner out there.

Two things that might help you; for local storage, I just checked in a new storage provider for Dojo Storage that will use the native storage abilities in Firefox 2 if they are available, in an automagic way; if they aren't there, then it will revert to hidden Flash like it's worked in the past. This might be useful for you; don't know what you were thinking about for local storage. There's a page up with better docs on Dojo Storage now at http://manual.dojotoolkit.org/WikiHome/DojoDotBook/Book50

The second thing is I just finished an HTML to OPML outline transformer; right now it adds in the line for the HyperScope XSLT stylesheet, but it can be used by any OPML hackers who want to play with bringing HTML into the OPML world, including for things like experimenting with the kind of OPath, deep linking, and inclusion work you've hinted about in other blog entries. A blog post on it is here: http://codinginparadise.org/weblog/2006/11/html-transformer-for-hyperscope-apply.html . Might be fun for you to use in your hacking.

We still need to grab drinks some time! How is your leg healing up? Hope you had a great thanksgiving.

Best, Brad

Working on a Tripkodoo business plan tonight

2005-10-28T14:32:29+00:00

Your company name:
Tripkodoo
Your company product:
opml-based collaborative document editing via microformats

Oh, hell. It looks like Web Two Point Oh! has nailed me on one of my stewing projects, Micronian. Sorta. Minus the OPML, really.

Though, hey, Tripkodoo sounds like a cool name...

FeedSpool is progressing nicely

2005-10-05T20:58:21+00:00

I'm at it again: Last night, I got an initial stab at a plugin API for FeedSpool working.

The first thing I built was an auto-adjusting feed poll schedule plugin which varies the time between feed polls based on whether there were new entries found in the latest poll. It's kind of like an AIMD algorithm used in networking—I thank Gnomon for the idea a few years back.

The next thing I built was a quick plugin bundle I call miniagg. If you'd like a preview, I've posted an HTML snapshot of what miniagg produces. It's a refinement and reworking of various aggregator UI pieces I've had floating around since AmphetaOutlines, only I think this is the simplest and cleanest I've gotten it yet. (CSS and unobtrusive JavaScript, hooray!)

This only seems to work on Firefox and Safari—it's currently broken for MSIE, and I don't care enough to fix it yet. (Something to do with multiple CSS classes, I believe.) But, if you're unfortunate enough to be using that browser, here's a screen capture:

I've been using a program called Rawdog for a while as my feed reader. Miniagg looks very similar to it. I've been looking for a replacement as he is not planning to support Atom 1.0 since feedparser has gone unmaintained. The HTML preview looks really good, I'm importing my subscriptions right now ;)

Alas, this miniagg uses feedparser also. However, I was thinking of patching / finding someone who'd patched feedparser for Atom 1.0—or replacing it with a new, maybe less liberal parser of my own, since FeedSpool is actually not all that liberal (in that it requires valid XML, anyway).

FeedParser Atom 1.0 support patch.

The feedparser page says that a prerelease v4.0 can be downloaded that includes support for Atom 1.0 feeds. Beats writing your own :)

Trac rocks like a really rocking thing

2005-09-30T16:11:09+00:00

Say hello to my new Trac installation!

For a couple of years now, I've been meaning to take a serious look at Trac. But, general level of busy, as well as random obstacles to getting it up and running kept me from getting very far. Such is so often the story with me.

Finally, though, I've gotten an instance running on our server here. All I can say is, "Wow!" This package does everything I ever wanted to cobble together using TWiki, MoinMoin, kwiki viewcvs, and any other pieces I ever looked at (ie. Bugzilla, Request Tracker, etc)

Trac has an amazingly dead-simple macro and plugin system which puts TWiki and possibly kwiki to shame. Just take a look at the MacroBazzar and this hacks collection. And, the system seems pretty cleanly architected—templates pages, simple extension points, SQLite database. I've already been able to easily wade in and make some tweaks of my own under the hood, as well as fix a few macro/plugins which were broken between v0.8 / v0.9 revisions.

Your mileage may vary, of course, but I think I've found my new favorite web app. It's now a replacement for the wiki and SVN repository browser I used to have running on 0xDECAFBAD v3.

I couldn't agree more - Trac is an absolute gem. It's even written in Python :)

My favourite thing is that you can use Wiki markup in the commit log. Sure, it doesn't work if you're not viewing it through Trac, but Wiki markup tends to be unobtrusive anyway.

My only complaint about Trac is how difficult it is to get installed and going. I consider myself a power user, though I'm not exactly a code whiz, and I still had a rough time getting it going on my OS X machine (and quite frankly never really did get it fully going). I suppose I'm spoiled by all of the great double-clickable installers that people make for these kinds of packages. :) If I knew more I'd figure out how to make one for Trac.

Re Trac on OSX - anyone tried http://trac.darwinports.com/ ?

I had the same grief with getting Trac running and then CVSDude offered it all nicely hosted for me. :) The price is right and the system works and it's exactly what I wanted.
