Hi Dave,

Thanks for taking a look. I think that even this much of a mention (that it seems to be uninteresting) is useful. It would help prevent others (like me!) from spending time looking into it. I also didn’t find it to be very useful, but was unsure whether it was my own fault.

best regards,
Marc

Marc:

To be honest, I couldn’t find a use for it, nor could I find anyone else using it.

Thomas: It’s described in several places—at the end of the tutorial chapter on containers, and under Symbol#to_proc.

1.9 is out but it is a development version! posted by Dave Thomas @ Sun, 27 Apr 2008 13:53:27 -0000

Skyblaze: 1.9 is intended to be a production version. It’s just that the initial release was pre-production; at some point Matz is likely to announce a 1.9 stable release.

Joachim:

In the new sections of the book (with red headings), the 1.0 symbols are accurate, reflecting new things in the language. Ignore them in the old sections.

RDoc::usage removed in 1.9 posted by Phil Hagelberg @ Mon, 31 Mar 2008 16:19:51 -0000

Actually, it looks like the usage.rb file is still present in my Ruby 1.9 installation (but not in the source checkout, which is extremely odd.) However, it appears the usage of usage may have changed:

~/src $ ./showtime.rb --help
/usr/local/lib/ruby/1.9.0/rdoc/usage.rb:100:in `initialize': No such file or directory - ./showtime.rb:29:in `<main>' (Errno::ENOENT)
    from /usr/local/lib/ruby/1.9.0/rdoc/usage.rb:100:in `open'
    from /usr/local/lib/ruby/1.9.0/rdoc/usage.rb:100:in `usage_no_exit'
    from /usr/local/lib/ruby/1.9.0/rdoc/usage.rb:93:in `usage'
    from ./showtime.rb:29:in `rescue in <main>'
    from ./showtime.rb:29:in `<main>'

showtime.rb was copied from page 259 of the PDF.

On pages 258-260 of the Pickaxe 3 PDF, it talks about the RDoc::usage tool. I tried using it in Ruby 1.9, and it seems to be absent. It looks like it was removed, since it’s definitely in my Ruby 1.8 installation but missing in trunk. See: http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/trunk/lib/rdoc/

The class Shell (from the standard library) seems to be (so far) undocumented. Finding any documentation for this class (and the nested goodies!) is very hard. I think the 3rd PickAxe would be a great place to find documentation…

Are the new pickaxe examples going to follow the jukebox from the previous versions? If so, wouldn’t it be worthwhile to add some “real-world” content that could help new developers when coming to ruby.

I notice that most of the 1.9 margin symbol seems to have been generated via a find and replace of the 1.8 symbol in the 2nd edition, perhaps for the next update you could remove them entirely, and add in the few that describes 1.9 behaviour as progress on the book is made.

With this new pickaxe that covers ruby 1.9 i thought that this was a stable version but i now discover that 1.9 is a development version so why this new edition that covers a development version of ruby? And when the 2.0 will be out? This book will be outdated!

for me in the pickaxe 2 you talk very briefely and very a little about self. So i would like to see in this edition a section that talk more about self and what it represents in different contests.

Howdy,

I’m missing an explanation of the wonderful &:. How about ‘line_items.to_a.sum(&:full_price)’?

Did the index at the back of PickAxe3 PDF get thrown out? If so, it needs to come back, that’s the best feature of PickAxe2 PDF. And the PDF menu/navigation of the index needs to expand alphabetically as it does in the Agile book.
