Cool Curl 'live' code widget

Over at eclectic-pencil I have a post on a very cool Curl widget that rivals almost anything I have ever seen expand and collapse on a web page.

What I neglect to mention is that in the example, the only code to create the XMl tree is this:

   let xmldoc:XDMDocument =
{build-xml preserve-whitespace? = false, loc}
|| ...
{XDMTreeControl open? = true, xmldoc.root}

Which you would be hard-pressed to beat in Seaside for Smalltalk or in Groovy. Concise.

TiScript also has an alternative DOM and some nice features as a JavaScript alternative, but Curl 5.0 is a mature, full RIA product with 'live' code for inspection and a focus on the client-side. It is almost Smalltalk but it was also built for the web (in fairness, Curl goes about as far back as Smalltalk VisualWave.)

The only cool but alive technologies as neglected as Curl 5.0 must be Gemstone/S and Rebol 2.6.3 ... and the latter is soon to be 2.7.x with 3.0 in the wings ...

Watch for a Seaside for Gemstone/S beta in the news soon ...

PS For people living on AIR and FLASH, Rebol/FLASH went 2.0 today ...
