Am I Ruby 1.9?

Description

So you want to move to Ruby 1.9 but you need your gems? Thanks to the folks at Brightbox we have Is it Ruby 1.9 and an API.

Building off the API announcement, conveniently released a few days before I needed it, I created Am I Ruby 1.9 to quickly determine how close your installed gems are to being ready.

The highly classified algorithm is listed below. The sum is merely the number of works_for_me true responses for the gem. Only the five most recent responses are considered.


rate = sum / recent.size.to_f
ratio = "#{sum} / #{recent.size}"

if rate >= 0.80
  works[gem_name] = ratio
elsif rate >= 0.40
  may_work[gem_name] = ratio
else
  fails[gem_name] = ratio
end

Please note that this doesn’t guarantee any gem will or will not work. It merely tries to guesstimate based on what other people have reported. Better ideas will be merged!

Another fine gem created with the help of simple-gem. Your definition of fine may differ, but simple-gem is pretty good and simple.

Be Nice

I have no idea what Is it Ruby 1.9 is using for hosting, but don’t overdo it if only to be nice to their servers.

Requirements

Am I Ruby 1.9 is “tested” with Ruby 1.8.⁶⁷, and requires the following gem:

json

Installation


gem install n3bulous-amiruby19

Usage

Right now, you just run amiruby19 with no arguments. After some amount of time directly proportional to the number of gems installed, you will see five different sections of output:

WORKS – 80% or more responses are positive.
MAY WORK – 40% or more of responses are positive
FAILS – Less than 40% of responses are positive.
UNTESTED – No responses are recorded for these gems.
MISSING – The gem is not known on Is It Ruby 1.9.

Example Output

Your output will look different, and this lists only the first 11 gems I have installed. This output will allow you “gem19 install” with some cut and paste to test the results.


WORKS
-----
activeresource acts_as_versioned activerecord addressable actionpack actionmailer

MAY WORK
--------
activesupport

FAILS

UNTESTED
--------

MISSING

TODO

Maintain a blacklist of working gems.
Ignore already installed Ruby 1.9 gems.
