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
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)”.

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

Talking to Java Code from Ruby

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

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

| I would like to use yajb because it’s pure ruby and pure java,
| no compiling, and installs are easy. The communication being slow
| 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
wrong parameters to the method, and he supplied a fixed version of

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

In the meantime, Kevin had got it working with RJB, and had
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
| like Ruby’s quirky big brother.

“You know you’ve arrived when people try to describe Perl by
comparing it
to you!”

Ruby PDA implementation?

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

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

gregarican gets Wince::Strerror exceptions with various operations.
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

Subversion 1.3.0 released.

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

RForum 0.2

Andreas S. announced the second version of RForum (web forum sofware
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
provides an easy-to-use Rake-based build for your software
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
hub for your family that includes a Family News section, and an

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
| roles. It was developed primarily to ease the pain of deploying
| applications to multiple machines, but can be used for a great deal
| 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")


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