Hi,

The 0.5 version of "Ruby/Tk GUI builder -- specRuby" is available on RAA
in the Applications/GUI section. (The Ruby Application Archive is at
http://www.ruby-lang.org/en/raa.html.)

From the description:

specRuby is a grid-managed GUI-based GUI builder that generates Ruby/Tk
code. (This is actually a Tcl/Tk application that was derived from
specPerl, which was derived from specTcl. Anyone want to help me make a
pure Ruby version?) Most of the basic things involving the display of
widgets seem to work, but some work remains to be done, such as wiring
up the scrollbars. More work is probably needed to handle things like
textvariables correctly. However, specRuby now appears to be adequate
for laying out GUIs. (And if someone who is more familiar with the
operation of Ruby/Tk wants to finish this up, the basic framework is now
in place. I have been somewhat hampered by the lack of English
documentation.)

Thanks to Mark Kvale for specPerl (which came in very handy a few years
back) and for his more recent advise.
