eintr: Why Count Words
Counting words
==============
The standard Emacs distribution contains functions for counting the
number of lines and words within a region.
Certain types of writing ask you to count words. Thus, if you write
an essay, you may be limited to 800 words; if you write a novel, you may
discipline yourself to write 1000 words a day. It seems odd, but for a
long time, Emacs lacked a word count command. Perhaps people used Emacs
mostly for code or types of documentation that did not require word
counts; or perhaps they restricted themselves to the operating system
word count command, ‘wc’. Alternatively, people may have followed the
publishers’ convention and computed a word count by dividing the number
of characters in a document by five.
There are many ways to implement a command to count words. Here are
some examples, which you may wish to compare with the standard Emacs
command, ‘count-words-region’.
