WishPerl is a pair of two (small) scripts, one in Perl and one in Tcl, enabling you of painlessly breeding Perl modules with Tcl/Tk/Tix GUI. Works on Unix with perl 5.004, on Mac with MacPerl and MacTk 8.0.4 (thanks to Rich Morin and Chris Nandor), and on Windows NT with YeP-perl (Windows '95 reports sought). With it's help, you can add Tcl/Tk GUI to your Perl program fast, or make a new application with GUI events processed by some Perl engine, or debug your Tcl script easily.

• Get Tcl/Tk from Scriptics site, get Tix from Tix Megawidget site if you wish.
• Get WishPerl here from our site (or you'd probably like it zipped, if you are on Win32 - here it is). Unpack and run test.pl included to see what happens. Tie with your code. Enjoy.

Here is a sample interaction, as implemented in test.pl:
