Whilst you could do it that way, as you point out, it means making extensive modifications to (presumably) already working code. It also means letting your tool (Tk) dictate the architecture of your application which is never a good thing. Especially as it would make turning the gui off for those gui-phobic *nix users very difficult.

Yes, the code is already working, with a thousand or so users. Indeed, I'm not too keen on the idea of rearranging the whole script into what seems to be a contorted structure to me just to accommodate Tk, hence this thread. Keeping the GUI on/off option probably wouldn't be too difficult, though. I guess I'd have something like
if ($gui) {
    require Tk;import Tk;
    # GUI stuff calling subs that do the actual operations
    MainLoop;
} else {
    # text prompts leading to calling the same subs as above
}
# SUBS

IMO the best alternative would be to stick your TK GUI into its own thread with a queue and tie that queue to stdin & stdout.

I understand the concept, but I have no idea how I would go about doing it. How complex would this job be? Much as I hate the idea of reshuffling the main script, it seems like the simpler option at this point - at least I have a pretty good idea of what it would involve. I guess I should note that I only code as a hobby, so there's a lot about perl that I don't know, and a fair bit that I'll never know. Can you describe the idea in a bit more detail and point me towards some code samples/relevant documentation pages? That'd help me decide whether it's feasible with my (lack of) skills.
