The Ruby Way: Notes and Updates

This is only a set of a few notes to clarify certain pieces of the book. Some of these items might be considered errata by some people; but the information here is mostly disjoint from the list of errata. In some cases, these notes are simply more up-to-date than anything available at the time the book's material was written. This list is very much incomplete and should be considered a work in progress.

Many functions such as sinh and cosh have been added to Ruby since the 1.6.x version.
The parsedate library has been updated. The time zone is now detected correctly after a meridian indicator (am or pm). It also recognizes a two-digit year preceded by an apostrophe.

My use of the word dynamicity is probably incorrect. Though I'm generally a language purist— English language, that is— I tend to stand by this decision. I'll address this issue elsewhere.
Chapter 6
FXRuby has evolved somewhat since this section was written. Be sure to look online for an explanation of the improved message handling.

This chapter doesn't mention REXML simply because I didn't know about it at the time of writing; in fact, I don't think it had been released then. But it is now probably the best and most common tool for parsing XML in Ruby.
