Method: Rex::Ui::Text::DispatcherShell#tab_complete

Defined in:
lib/rex/ui/text/dispatcher_shell.rb

#tab_complete(str) ⇒ Object

This method accepts the entire line of text from the Readline routine, stores all completed words, and passes the partial word to the real tab completion function. This works around a design problem in the Readline module and depends on the Readline.basic_word_break_characters variable being set to x00
