Ruby has been a joy for me to learn and that positive experience has led me to try certain tasks I had previously hesitated to undertake.
Building a Xapian database for searching, for instance. I first tried using the standard Xapian bindings, but then I found xapian-fu, a much more Rubyish gem.
It works fine with ruby 1.9.1 for me and is quite speedy. Here's a very simple example for a search (using the databases generated by the debian package apt-xapian-index):
#!/usr/bin/ruby1.9.1 require 'xapian-fu' include XapianFu db = XapianDb.new(:dir => '/var/lib/apt-xapian-index/index.1') db.search(ARGV).each do |match| puts match.data end
