Ruby "Save Game" function
Hello! I am currently working on a text-based RPG and I wanted to implement a function that allowed the user to save their game at any point, so that it could be resumed later. Of course, this would need to be complimented by a load function that would resume the game at that previous state. Anybody know how I... 17 Feb 2010 20:11

Parallel assignments vs. Serial assigments
Hey all I was always under the impression that parallel assignments in Ruby were faster than assigning variables individually. Recently I was curious to see how much faster it was and decided to test it: class One def initialize(first_name, last_name) @first_name = first_name @last_name = las... 17 Feb 2010 00:06

what's the nearest ruby equivalent to waf?
http://stefano.italians.nl/archives/66 is a pretty nice example of using waf, a python build tool, instead of autoconf and make, to build a c++ project. Is there a ruby build tool that can be used for something similar? (This is not a case of NIH; looking at the waf script in that example, I can imagine it being a ... 14 Feb 2010 14:01

Delegating testing to another class
This is probably funky.. :-) I'm writing some tests with Test::Unit::TestCase, and I want them to be data-driven. I want to abstract the assertions to another class (call it TestIt) more tightly tied to the data. So far, I either get NoMethodError exceptions because TestIt isn't subclassed from Test::Unit::Te... 13 Feb 2010 16:02

Question about load(). WasRe: [ANN] envjs rubygem 0.1.1
Steven, How closely does the env-js gem follow the docs for the Rhino based project? For instance: window.location="some.html" that has a script tag that loads jquery.js, seems to be loading that external file. The server logs a GET for it anyhow, and it seems to be live within evaluates. But the docs say you... 13 Feb 2010 14:54

[ANN] Zbatery 0.1.1 - leak fix from Unicorn

Also some minor documentation updates. * http://zbatery.bogomip.org/ * rainbows-talk(a)rubyforge.org * git://git.bogomips.org/zbatery.git -- ... 13 Feb 2010 06:02

Sorting numbers.
I read a line from a CSV file as the following: fooone,22,114,66,125,footwo and I would like to sort the numbers from index 1 to 4, but I can't convince the sort function to work with integers instead of strings. The result of sort is always 114,125,22,66 as it is sorted by the first ASCII character. The to_... 13 Feb 2010 16:02

Rmagick DNG
I am using RMagick to process photos that are in the DNG format. However, RMagick seems to just use the thumbnail version of the image. How do I tell it to use the full resolution image? require "base64" require "rubygems" require 'RMagick' include Magick f=File.open(file_name,'r') p = Image.read(f) p[0]... 15 Feb 2010 15:27
