[ANN] rubytorrent 0.1 (bittorrent for ruby

William Morgan

1/4/2005 5:00:00 AM

Hello all,

I'm happy to release RubyTorrent 0.1. RubyTorrent is a pure-Ruby
BitTorrent peer library. Changes in version 0.1 include many bugfixes
(Windows platforms now fully functional) and enhancements (snubbing
support, API improvements, http_proxy). You can get it at:

http://www.masanjin.net/~wmorgan/rubytorrent/rubytorrent-...
(RubyForge project coming soon.)

RubyTorrent is around 1500 lines. I've included a simple command-line
text peer program, rtpeer.rb, for you to play around with. The API is
also slowly changing into something useful. From the "docs":

Synopsis
--------

## world's smallest bittorrent client
require 'rubytorrent'
bt = RubyTorrent::BitTorrent.new(ARGV.shift)
thread = Thread.new do
while true
puts bt.percent_completed
sleep 15
end
end
bt.on_complete { thread.kill }
thread.join

Comments, bug reports and patches always welcome. Have fun.

Hi William,

It looks like you can add support for remote torrents by changing two
lines. Here's a diff (I'm sending it to the list for discussion):

With this change, RubyTorrent can then handle URIs to torrent files transparently, like so:

bt = RubyTorrent::BitTorrent.new('http://www.legaltorrents.com/bit/wired-creative-commons-cd.to...)

Hope this helps...

Thanks. I'll incorporate that in in 0.2.
