Objects in Motion


This may sound complicated, but if you’re using VIM to begin with you obviously have a pathological lack of any fear of complexity.

The definitive book on regular expressions is by Jeffrey E.F. Friedl, Mastering Regular Expressions from O’Reilly (now in its second edition).

David Ascher said of this book, “Jeffrey Friedl’s book is IMO one of the few that I own that I think are worth the price, even though its Python knowledge is obsolete and I use regexps as sparingly as I possibly can.  If nothing else, it is proof that the human mind will delve obsessively into arcane knowledge for no other reason than because it can.”  High praise, indeed.

Add ranges to vcq.py.  Hint:  look at my getargs module, which can be found at Software, near the bottom of the page.  It’s fully documented, of course: see getargs.html.  When you add the ranges, send the changes to me, and I’ll give you a credit.
