Purple Numbers and WIKIWYG

For a while, it was looking like I was going to break another personal blogging record last month, then things got so busy I had zero time to blog whatsoever. That means I’m in catch up mode again, so as usual, I’ll post in reverse chronological order (which in the blogosphere is really reverse reverse chronological order).    (JYN)

Yesterday, I spent the afternoon at Socialtext, where they were having an all-hands meeting. They graciously invited me to participate in the Open Space segment of their gathering, which meant quality time with Chris Dent and a rare opportunity to evangelize the Church Of Purple together. Of course, Chris has been spreading the Purple religion at Socialtext for a while now, so it wasn’t as much about evangelism as it was about next steps.    (JYO)

As I’ve mentioned many times before, browser-based WYSIWYG editors are an exciting development because they allow us to make Purple Numbers transparent in the authoring process. Right now, when you edit a PurpleWiki page, you see the node ID tags (e.g. {nid 123}). This is impossible to get around with the default browser text-editing widget. However, with a WYSIWYG editor, you can hide the Purple Numbers while still maintaining their associations with a node behind the scenes.    (JYP)

That’s the theory, anyway. In particular, I’ve been excited about WIKIWYG ever since Ross Mayfield showed me an early prototype last August. I had a personal bias, since Chris Dent and Matt Liggett helped write it, as did Casey West and the inimitable Brian Ingerson, whom I finally met last weekend at Tag Camp.    (JYQ)

Yesterday afternoon, we discussed Purple Numbers and WIKIWYG, and it was good. Then in the evening, Ingy and I spent a few hours trying to get WIKIWYG integrated into PurpleWiki.    (JYR)

We didn’t quite make it. Our biggest roadblock was a bug we discovered in Mozilla’s design mode that we can’t do much about. (My days of statically typed languages are well behind me.) But, we got something somewhat working, and I learned a heckuvalot. You can play with our semi-working demo.    (JYS)

WIKIWYG seems well-architected and is easy to customize. For folks with relatively standard Wiki editing requirements, I highly encourage you to play with it. PurpleWiki has some special formatting funkiness (mainly due to the Purple Numbers), but we were able to get around this fairly easily. (This was also true thanks to PurpleWiki‘s model of parsing to an intermediate data structure, then using view drivers to serialize. I wish more Wiki engines did this. I know Magnus Manske is thinking about doing this for Mediawiki, and I think Janne Jalkanen is already doing it with JSPWiki.)    (JYT)

The Mozilla bug annoyed me, because it’s a show-stopper in some ways, and there’s not much I can do about it. I didn’t realize it, but all of the JavaScript WYSIWYG widgets actually switch to the browser’s “design mode” in order to handle WYSIWYG editing. As with many HTML editors, design mode does not handle structure cleanly, and you end up getting weird artifacts such as spurious break tags. Our problem was that we serialize node ID information as id attributes in the HTML tags. However, Firefox does not maintain those attributes correctly when you move content around.    (JYU)

I’ll report the bug (if folks have suggestions as to the best way to bring this to the right people’s attention, let me know), but it also puts the kibosh on my hopes for WIKIWYG and Purple Numbers. Even if the bug is fixed in the next version of Firefox, we’re still prey to all the folks using older versions as well as Internet Explorer or Safari, which have their own problems with design mode.    (JYV)

Chris and I discussed one workaround that I’m still pondering: render the Purple Number and have users be responsible for maintaining the association with the nodes. That’s the status quo, except users are doing it in WikiText rather than in WYSIWYG. Doing it in WYSIWYG certainly lowers the bar, and it’s probably the next best thing for us to do.    (JYW)
