It is often useful to view the results of filtering large amounts of text.;;; Typically you do this with various combinations of grep and friends. When doing so it requires explicit effort to not destroy the original text being filtered. This module provides a textfilter utility that: A) Copies over the selected text to a special filtertext buffer B) Implements a filtertext mode for that buffer that allows easy application of filters C: Provides commands for reverting to the original unfiltered text D: Provides commands for saving results from intermediate filters.
