Lively TclTk

Lively-Kernel meets Tcl/Tk?

My latest install of Tcl/Tk 8.5 from Activestate left a link in Windows to Tk demos.  One is named "A Celebration of Rube Goldberg" and should impress Self-as-JavaScript  fans of Sun LivelyKernel or Avocado.

Regardless of the grief in getting Tcl with OO out of 8.6 beta, the demos are a great presentation.  I continue to use Html Viewer 3 (Tcl/Tk's hv3 browser) as a light-weight browser when my laptop's sole-core is over-loaded with a few of today's greedy app's wildly swapping in and out (and no, the worst offender happens not to be from Microsoft.)

Btw, Squeak Smalltalk is working to get their base image down to about 10Mb.  Remember when shared DLL's were to keep us all happy below 640K ?  Gates' Hades, Hades' Gates.

PS: I have added a label/tag for Pharo Smalltalk - now the preferred ST for Seaside?

PPS: here is the Avocado blog: there.

Tcl 8.6

The manual page is at http://www.tcl.tk/man/tcl8.6/ but TclOO may not be final yet for 8.6 ?

A default O-O package for Tcl 8.6: TclOO

 
While the link for O-O Tcl looks to be dated, the page for Tcl 8.6 releases is current.

I have a bias for XOTcl, but I will try to be open-minded when 8.6 gets out of beta.

TclOO is intended to offer classes and objects as a Tcl package rather than as an ad hoc extension to Tcl and Tk.  Some "patterns" folks will like the hiding of new in class in favour of create as the class declaration idiom - but instances are created via a command block substitution with the new word as in

set obj [MyClass new]

A google of TclOO and Tcl failed to get me past beta1 links to Tcl8.6b2 links.

But the link to the PDF on the new engine looked interesting.

This link at tcl.tk may be the final URL for core TclOO.

Over at activestate.com Tcl remains at 8.5.8 with a release number of 8.5.8.2 as of today.

Tcl 8.5.9 added the ttk::spinbox command.

A google on "Tcl 8.6" gives some useful links such as that to Mark Roseman's 8.6 page (he is the author of the tutorial for Ttk or Tile/Themed Tk.)
