TkCon is a Tcl shell and console, making it ideal for experimenting with Tcl and Tk programs interactively.

Features: Command history Path (Unix style) / Proc / Variable name expansion Multiple consoles, each with its own state (via multiple interpreters) Captures stdout and stderr to console window (puts overridden) Hot errors (click on error result to see stack trace) Electric character matching (a la emacs) Electric proc highlighting Communication between consoles and other Tk interpreters (including non-Tcl ones)
