It’s meat and potatoes time.

As I’ve mentioned in earlier posts, I’ve spent some time creating a “preview” or rendered view of a XML document the user is editing:

Of course, seeing the document alone is no fun. You want to be able to edit it. That’s what Verbosio is for.

So let’s say you hit Ctrl+E (right now you have to click) on the selected menu item. What do you get? How about, oh, an interface for changing that menu item’s properties?

This is what I’ve been dreaming of for the last year and a half: a way to edit XUL on the fly, visually. (Of course, it’s not just XUL – not in the long run. XUL’s simply what I chose to work with first.)

It’s also supporting my vision for Verbosio: having extensions drive most of the work, while Verbosio handles the common tasks. The preview viewer is provided by a Verbosio extension. The yellow box is provided by Verbosio’s core, while its contents (the “XML markup template”) come from another Verbosio extension. Support for the document you see comes from the same Verbosio extension as the markup template, a XUL language extension. The XUL language extension also provides some metadata about the XUL language in another component (including some basics about how to handle whitespace). Another extension told Verbosio how to open the chrome application the user is editing.

This is a starting point. I’m going to expand it soon, so that you can:

• Work with sets of elements (like radio buttons inside a radio group, or cells in a table)
• Build your own templates within Verbosio, using documents you have open in Verbosio
• Edit DTD localization entities underneath the labels you see
• Create templates for creating new documents in supported XML languages from scratch

Sometime after that – once I fix other API issues and some pretty important regressions – I’ll release Verbosio 0.1 alpha 1. My changelog is in the extended entry.

In the meantime, I’m also very aware of the need to get other eyes on the code behind Verbosio. Just recently, Paul Rouget borrowed my chrome registry viewer code for his CodeEditor tool. That to me is a solid vindication of what I’ve been trying to do.

At the same time, the entire Verbosio code base is unreviewed and only partially documented. Sooner or later, I’m going to need volunteers who are willing to work with Verbosio – and me – and improve the hackety-hack code I’m crafting from scratch. Very little of this code, as it now stands, would pass any realistic peer review. So I will start asking, as of now, if other people want to directly involve themselves in the Verbosio project over the next few months.

I just want fellow developers to start thinking about it. I couldn’t really do that before, because it’s so hard to put into words what Verbosio is all about. Now, hopefully with the screenshots above, the vision can become clearer.

For now, though… the steak’s on the barbecue.
