This is the full tkcon script when run inside the plugin. It feels like a stripped down version of tkcon, but the only limitations are those established by the plugin. You can test the basic console features and get a feel for the mutli-color output. Below the demo are some ideas to try out. v2+ of the plugin is distributed with a megawidget version of tkcon for debugging tclets. The demo below uses the CVS head of tkcon.

Have a look at some of the features: (culled from the tkcon documentation)

• Variable / Path / Procedure Name Expansion. Type in set tc at the prompt. Hit <Control-Shift-V>. set tcl_ should now be visible. Hit <Control-Shift-V> again. You should see the rest of the completions printed out for you. Works the same for procedures and files paths (file access restricted from plugin). Works properly when spaces or other funny characters are including in the name.
• Command Highlighting. Note that set should be in green, denoting it is a recognized command in that interpreter.
• Electric Character Matching. Watch while you type the following: proc foo { a b } { puts [list $a $b] }. Did you notice the blink matching of the braces? Yes, it's smart.
• Command History. Use the Up/Down arrows or <Control-p>/<Control-n> to peruse the command history. <Control-r>/<Control-s> Actually does command history matching (like tcsh or other advanced Unix shells).
• Useful Colorization. Having defined foo above, type in foo hey. Note that the error comes back in red. Go up one in the command history and add you and see that regular stdout output comes through in blue (the colors are configurable).
• Cut/Copy/Paste. You should be able to do that between outside windows and TkCon. The default keys are <Control-x>/<Control-c>/<Control-v>.
