Anyway, if you found this, you probably don’t want to listen to me blabber, you want to know how to get it running on Ruby 1.9.x, so I humbly present a patch!

Download the patch here (older version) version 2

Download the patch here, version 3.

First, download the FastRI tarball (version 0.3.1 is latest at the time of this writing) from rubyforge.

Here’s how to install the patch:

% tar zxf fastri-0.3.1.tar.gz
% cd fastri-0.3.1
% patch -p1 < ../fastri-0.3.1-ruby1.9.1.v2.patch
patching file bin/fastri-server
patching file lib/fastri/ri_index.rb
patching file lib/fastri/ri_service.rb
patching file lib/fastri/util.rb
patching file test/test_functional_ri_service.rb
% sudo ruby setup.rb

And you’re done! Now you’ll need to make sure to do a ‘fastri-server -b‘ to build the cache, and from there you can use FastRI the same as it was in Ruby 1.8, see:

[hinmanm@Xanadu:~]% qri String.each_codepoint
-------------------------------------------------- String#each_codepoint
str.each_codepoint {|integer| block }    => str
From
------------------------------------------------------------------------
Passes the Integer ordinal of each character in str, also known as
a codepoint when applied to Unicode strings to the given block.
"hello\u0639".each_codepoint {|c| print c, ' ' }
produces:
104 101 108 108 111 1593

Notes/Caveats/Disclaimers & Warnings:

This patch is a WORK IN PROGRESS, it may hang, crash, steal your wallet and/or delete files. I hacked it up in a day looking at FastRI because I really like using ‘qri’ for everything and was consistently annoyed by getting docs intended for 1.8. I assume no responsibility for these things.

Also, note that all tests don’t pass with this patch, I’m still working on it.

Feel free to leave any feedback for me

UPDATE:
New version of the patch that fixes doing a lookup on a base class instead of a method. so… version 3 right now. (link above)

UPDATE2:
I created a github project for fastri to build a gem, so you can install the gem (without patching!) using this command:

sudo gem install dakrone-fastri -s http://gems.github.com
