        ShiftReduceApp

A graphical tool for exploring the shift-reduce parser. The tool displays the parser's stack and the remaining text, and allows the user to control the parser's operation. In particular, the user can shift tokens onto the stack, and can perform reductions on the top elements of the stack. A "step" button simply steps through the parsing process, performing the operations that nltk.parse.ShiftReduceParser would use.

__init__(self, grammar, sent, trace=0)
(Constructor)

source code 
Overrides: object.__init__
(inherited documentation)

mainloop(self, *args, **kwargs)

source code 

Enter the Tkinter mainloop. This function must be called if this demo is created from a non-interactive program (e.g. from a secript); otherwise, the demo will close as soon as the script completes.
