DWITE will be starting up again this year, beginning with an Earlybird contest on October 3. Visit www.dwite.org for all of the details. I beleive there was a bit of interest in including Ruby submissions. If someone can direct me to a copy of a command-line compiler for Ruby, I'll look into including it. Cheers. Mr.S.

Ruby programs are not typically compiled... they're interpreted. You just run the following, and it goes about its way.

code:

ruby myfile.rb

You can fetch the one-click-installer for Windows here.

excellent the bulk of my commentary is posted at the compsci.ca blog, though in summary - "register if you can" Ruby would make programming contests too easy

Too late to join? I just found out about DWITE

Re: DWITE 2006-2007

I now have Ruby-185-21 installed on the DWITE Judge's computer. I also have RubyScript2Ex3e from http://www.erikveen.dds.nl/rubyscript2exe/index.html also installed on the computer.

This may seem like a simple request, but I need someone to write me the Ruby code for the following problem. Once I have the code I can test out Ruby on the DWITE judge.

Thank you. Mr.S.

Sample Problem

Write a program that will calculate the square of a number rounded to two decimal places.

The input file, DATA11.txt, will contain 5 numbers, on separate lines, each between -32768 and 32767.
For Example:
0
23.45
-1234
-32760.789
999

The output file, OUT11.txt, will contain, left justified, on five lines, the squares of the corresponding values from the input file.
For Example:
0.00
549.90
1522756.00
1073269295.90
998001.00

sure thing

Ruby:

outFile = File.new("OUT11.txt","w")
File.new("DATA11.txt","r").each_line{|num|
outFile << sprintf("%0.2f", num.to_f*num.to_f) << "\n"
}
outFile.close

Well I seem to have Ruby working on the DWITE judge. RubyScript2Exe - A Ruby Compiler makes a honkin' huge .exe of the sample program below (1,140 KB). The .exe is very slow also...aproximately 1300 milliseconds, compared to approximately 100 milliseconds with a Pascal submission. Teams are welcome to try submissions in Ruby for the next contest.

What is the purpose of 'compiling' Ruby to an .exe anyways? It's an interprative language, just run it through an interpreter

code:

ruby PROGRAM11.rb

granted that the judge would need to be modified for this case. So instead of the usual

compile -> run out.exe

it would skip compile and go straight for

ruby out.rb

The performance should be _much_ better though (and I'm not sure on how compatable RubyScript2Exe is

Yes, the judge would be need to be modified to handle this case. I was just keeping consistent between the several different programming environments. I'll see what happens in the November contest, to determine if I should modify the code.

Which makes me think about Turing....Is it possible to run a Turing solution this way also? Something like...

code:

winoot program11.t

I could probably look into it, but if someone knows, it could save me some time.

weren't we all looking for a command line turing compiler a while back, and got a non-working executable from Tom?

The Ruby "compiler" simply statically links your program into the Ruby interpreter. This is essentially how the Turing "compile" works as well. There is no reason a Ruby program handled this way would be any faster than any other Ruby program, as it is still being handled by the same interpreter.

Yep, i even tested that thing on every verson of turing know and not know to exists. Incuding such unreported copys as 4.0.5 and 4.1. Also e-mailed tom myself serveral times and have never got a responced from him. Maybe he died?
