using Ruby2.0 on Heroku

Are you using Ruby2.0 already?

I think almost peopleare not trying Ruby2.0 soon,

because it might be dangerous

Heroku has flexible runtime

configuration system

You can use any languageson Heroku

$ heroku create --buildpack <BUILDPACK_URL>

https://devcenter.heroku.com/articles/buildpacks

So you can use Ruby2.0 on

Heroku with your own buildpack

or

with bundler

ruby “2.0.0”

Heroku already provided sandbox for evaluate Ruby2.0

You can use Ruby2.0 on Heroku now

$ vim Gemfile$ cat Gemfilesource :rubygemsruby "2.0.0"$ bundle install$ git init$ heroku create$ git add .$ git commit -m ‘ruby-2.0.0’$ git push heroku master

$ cat Gemfilesource :rubygemsruby "2.0.0"gem "rack"$ cat Gemfile.lock GEM remote: http://rubygems.org/ specs: rack (1.4.1)
