Title Case in Emacs

I wrote a small Emacs Lisp library, titlecase.el for converting text to title case in Emacs. It provides three functions:

• titlecase-string converts a given string to title case and returns the result.

• titlecase-region converts the given region to title case.

• titlecase-dwim converts the region to title case, if there is an active region, or converts the current line to title case.

Rather than reinvent the wheel, this library is currently a wrapper for the titlecase Perl script written by John Gruber and Aristotle Pagaltzis. Place the titlecase script in a directory that’s in your Emacs exec-path and make sure it’s executable. Otherwise, you’ll need to change the value of the variable titlecase-command to be the full path to the script on your system.
