Threads
=======

  Dice Roller (#61)
  -----------------

   Matthew D Moss came up with this week's Ruby Q..

   "Time to release your inner nerd."

   Write a dice roller for D&D-like games that takes an expression like
   "5d5-4)d(16/d4)+3" and the number of times to roll the dice, and
returns
   stats for your character.

   "The meat of this quiz is going to be parsing the dice expression".

   Matt L.: "REAL gamers roll 100 sided dice (aka Zoccihedron)".

  XML pretty printing?
  --------------------

   Chris McMahon asked if Ruby has any libraries to make "pretty" XML?

   James B. said that REXML has options for outputting XML with
   indentation, see e.g. REXML::Document#write.

  ruby-dev summary 28027-28205
  ----------------------------

   Takaaki T. summarised the Japanese mailing list ruby-dev.

   Process.exec has been added to Ruby 1.9, and patches were also merged
   allowing Intel's compiler to compile Ruby on IA64. (But some tests
still
   fail.)

  Talking to Java Code from Ruby
  ------------------------------

   Kevin B. was using YAJB (Yet Another Java Bridge) to utilise the
Java
   library JasperReports from Ruby, but was getting a "No such method"
error
   when trying to call a particular overloaded method.

   "So is there a way to specify types for overloaded methods, or do I
need
   to use RJB?"

   | I would like to use yajb because it's pure ruby and pure java,
meaning
   | no compiling, and installs are easy. The communication being slow
makes
   | almost zero difference to me because I won't be doing very much
   | communication, just spawning off processor hogs with the thing.

   Masashi Sakurai said that the error was correct - Kevin was passing
the
   wrong parameters to the method, and he supplied a fixed version of
his
   code.

   "The yajb tries to search the overloaded method as java does. So,
giving
   appropriate arguments, you can choose the method."

   In the meantime, Kevin had got it working with RJB, and had
presumably
   made the same fix somewhere along the line.

  Another milestone for Ruby!
  ---------------------------

   Jeremy H. reported from the Jifty home page:

   | Jifty is written in Perl. If you're familiar with Ruby, Perl might
feel
   | like Ruby's quirky big brother.

   "You know you've arrived when people try to describe Perl by
comparing it
   to you!"

   Almost ...

 15:05 <obra> My plan worked perfectly. the perl as ruby's quirky
brother
 comment was intended to get ruby people to laugh

   Jifty is a web application framework for Perl, featuring
continuations,
   form-based dispatch ("you never need to write form handling logic"),
and a
   pony.

  Ruby PDA implementation?
  ------------------------

   We accidently reported on an old Ruby-on-mobiles thread last week,
but
   this one's definitely fresh, and has more information than the old
one.

   gregarican re-asked about Ruby on PDAs, and Jason Tell linked to his
blog
   post showing success at running Ruby on an iPAQ with the Windows
Mobile
   operating system.

   gregarican gets Wince::Strerror exceptions with various operations.
Does
   anyone have an idea?

New Releases
============

  KirbyBase 2.5.2
  ---------------

   Jamey C. made a new release of KirbyBase, a pure-Ruby database
   management system that uses plain text for all its files.

   KBTable#insert behaviour has changed. If the user specifies nil for a
   field then nil will be used, rather than the default value of the
field.

  Subversion 1.3.0 released.
  --------------------------

   Kouhei S. noted the release of Subversion 1.3.0, which now comes
with
   complete Ruby bindings.

  RForum 0.2
  ----------

   Andreas S. announced the second version of RForum (web forum sofware
that
   also integrates with mailing lists).

   Many improvements were made, including new stylesheets and support
for the
   Ferret search engine.

  Rote 0.3.2 released
  -------------------

   "Rote is a lightweight, powerful documentation and templating system
that
   provides an easy-to-use Rake-based build for your software
documentation
   and other static text for the web."

   Several new features were added, and bugs fixed.

  Family Connection 1.0
  ---------------------

   Duane J. released 1.0 of Family Connection, "an easy-to-setup
online
   hub for your family that includes a Family News section, and an
Address
   Book."

  SwitchTower 0.10.0
  ------------------

   Jamis B. announced a new version of SwitchTower, fixing "several
   longstanding issues", as well as adding some new functionality.

   "I anticipate one (or at most two) more releases before 1.0."

   | SwitchTower is a utility that can execute commands in parallel on
   | multiple servers. It allows you to define tasks, which can include
   | commands that are executed on the servers. You can also define
roles for
   | your servers, and then specify that certain tasks apply only to
certain
   | roles. It was developed primarily to ease the pain of deploying
Rails
   | applications to multiple machines, but can be used for a great deal
more
   | than that.

  Rio 0.3.7
  ---------

   Rio now supports pipe syntax and behaviour, and has improved
treatment of
   Windows paths.

   Rio is a "Ruby I/O convenience class wrapping much of the
functionality of
   IO, File and Dir."

   An example:

####
 Create a tab separated file of accounts in a UNIX passwd file,
 listing only the username, uid, and realname fields
  rio('/etc/passwd').csv(':').columns(0,2,4) > rio('rpt').csv("\t")
####

   Harpo:

   | Bravo !
   |
   | ... Because :
   | . It is very useful.
   | . It is well documented.

  Instant Rails 1.0 Final has been released!
  ------------------------------------------

   Curt H. announced Instant Rails 1.0 Final.

   | Instant Rails is a one-stop Rails runtime solution containing Ruby,
   | Rails, Apache, and MySQL, all preconfigured and ready to run. No
   | installer, you simply drop it into the directory of your choice and
run
   | it. It does not modify your system environment. This release of
Instant
   | Rails is for Windows, but there are plans for ports to Linux, BSD,
and
   | OSX.

   The Final release is the same as the Release Candidate 1.
