Overview

Package regexstyle provides a widget that highlights the content of its subwidget according to a regular expression. The widget is also given an occurrence parameter which determines which instance of the regex match is highlighted, or if -1 is supplied, all instances are highlighted. The widget currently wraps a text widget only since it depends on that widget being able to clone its content.
