tkcmd - enter Tk commands interactively


tkcmd [ -iu ] [ tkarg ]


Tkcmd allows interactive entry of Tk commands; it is useful for testing out features of Tk prior to incorporating them in a Limbo program. It accepts two arguments:

Force interactive mode. In interactive mode (the default if the standard input is directed at /dev/cons), a prompt is printed before every tk command entered.
Suppress the automatic tk update command after every entered command.

When tkcmd is started, a new top level window is created; tkcmd creates a titlebar and handles all the normal window window manager interactions. When the window is closed, tkcmd terminates. Each line typed to tkcmd is passed directly to the function Tk->cmd (see tk(2)) and executed in the context of the top level window; a Tk ``update'' command is then issued. Any return value from the command is printed. There is one predefined Tk channel, named ``stdout''; anything sent down this channel will be printed to the standard output.
