public class WordsCommand
extends Object
implements LpexCommand

Sample command words - count the words in the current view. Displays the number of visible words and non-space characters in the text. If a selection is in effect, only the selected text is considered.

A simple scanning for letters and digits is used, rather than a BreakIterator, which is sufficient for most types of programming source documents. A word can be optionally defined to consist of any consecutive non-whitespace characters.

Here is the WordsCommand source code.
