Multiple apps, multiple gemsets, one Ruby to rule them all.

Question

My account's a mix of PHP and Ruby applications. What do I need to type into my .bash_profile to handle:

one gemset per app
Ruby 2.0 for everything that isn't PHP
Bundler never again telling me "Your Ruby version is 1.8.7, but your Gemfile specified 2.0.0"

I read WF's gem docs and have no idea what to actually type where. How do I pull this off?

Each application has its own ruby binary and gems path for a reason. It is best practice to keep them separate. When you need to install gems for a given application you would follow steps 1-6 in this documentation. By invoking the export commands in steps 2-5 you are setting the gems and binary path for the rest of that session.

I've got seanf's answer in mind: "If you don't want to set them manually each time, then set them in your .bash_profile - but be aware that you'll need to override them if you're working with multiple apps."

What that means that if you have appA and appB, and you put this in your .bash_profile...

export GEM_HOME=$HOME/webapps/appA/gems
export RUBYLIB=$HOME/webapps/appA/lib
export PATH=$HOME/webapps/appA/bin:$PATH

... then your shell environment will be configured to work with appA, and not appB, and that if you want to work with appB, you'll need to reset those variables accordingly.
