I've put together a list of 81 errors and updates to my Ruby book. These are fixed in the next printing. If you already own a copy of the book, however, you can go through and enter the changes yourself, if you are so inclined.
I use O'Reilly's style for describing the changes. Each entry in the file begins with a page number within delimiter characters. The delimiters indicate the severity of the change:
- Page numbers in parentheses usually indicate typos or other minor non-technical changes. You can ignore these if you want.
- Page numbers in curly braces indicate minor technical errors that have been corrected
- Page numbers in square braces indicate more severe technical errors that have been corrected. There are only two of these, but they're worth noting.
- Page numbers in angle brackets are updates (this differs a bit from normal O'Reilly style) to keep the book in sync with the evolution of Ruby 1.9. In my opinion, these are the interesting ones.
I've posted my list of changes here. They will all eventually appear on O'Reilly's errata page for the book as well.
