Igloo is a project to build a [Snit]-like layer on top of [TclOO].  The goal is to provide all of Snit's convenience in the context of TclOO, rather than to provide a drop-in TclOO-based replacement for Snit.  In particular, while I intend the syntax (e.g., for delegation) to be similar to that of Snit, I do not intend to slavishly follow Snit syntax.  Rather, what I'm looking for is a TclOO-based package that is so pleasant to use that I'll gladly leave Snit behind.

***Download***

The current version of Igloo can be found at https://github.com/wduquette/igloo%|%GitHub%|%.  Feedback is welcome.

***Notes***

Nothing about Igloo (including the name) is graven in stone at this time.  

***History***

Some years ago I began a similar effort that never really got off the ground.  Since then I've spent a considerable amount of time using TclOO alongside of Snit, and have a better notion of what's desirable and what's doable.  The remaining text in this section is from my initial "iGloo" efforts.

iGloo is a project investigate the implications of building [Snit's Not Incr Tcl] on top of [TIP #257: Object Orientation for Tcl].  At present it's less a software product than a series of blog posts [http://foothills.wjduquette.com/blog/archives/category/programming/igloo/] about the issues I run into and how I solve them.  I may make bits of code available as well; if so, they'll be found at [http://www.wjduquette.com/igloo/].  Note, though, that any code I make public is subject to change without notice.  -- [WHD]

'''A note on the name:''' A couple of years ago, when Snit was beginning to catch on, there was a time when I seriously thought about changing its name.  "iGloo" is my favorite of the names I came up; you can pronounce it "ig-loo" or, alternatively, "I Glue".  I pronounce it the first way, but I mean the second.  -- [WHD]

'''Status:''' 02/03/2010 [http://groups.google.com/group/comp.lang.tcl/browse_thread/thread/b504555f88ae04ae?hl=en]

"The "iGloo" project is pretty much defunct.  At this point, TclOO 
lacks two things that Snit needs: hierarchical methods (methods with 
subcommands, like the text widget's tag command), and direct support 
for configure/cget options.  Of the two, hierarchical methods are the 
more critical...but Donal's been working on that"...

"Ultimately, I expect that TclOO will mature to the point that Snit is 
unnecessary, or Snit 3 will be built on TclOO.  Unfortunately, as I 
said in another post, I really need support for hierarchical methods, 
and it's not there in TclOO yet"...

'''Discussion'''

[RLH] I am glad you stuck with Snit!  ; )

[WHD] Would just plain "Gloo" (punning on both "Glue" and "OO") be better? 

[RLH] It doesn't screem at me like iGloo does. Snit is better though.
