Hi

I need to add role/environment specific variables for a (legacy) capistrano multi server, multi-role, multi-environment setup.

See example and details at http://stackoverflow.com/questions/15619945/capistrano-how-to-access-a-serverdefinition-option-in-the-code

How can I define a variable in my server configuration, which is accessible from my tasks?

Also I would appreciate any similar examples. Perhaps there is a simpler way than the one I am pursuing here?

Any feedback greatly appreciated :)

Thanks for your reply. 

Any time, keep in mind, I'm speaking about as-yet unreleased stuff, so YMMV, no warranty, etc.

You iterate over "hosts" in the example like this:

    on hosts do |host|

     ...

  end

When I understand the way it's been build properly (and I haven't written that part of the code myself) - the roles are available through a variable that you can treat in a similar fashion, but `on(roles)` is meaningless, you'd need to do `roles.each { |role| on(role.hosts) }` or something.

However, I haven't written the Cap v3. role code, you'll have to go spelunking in the code, sorry.

Just for the record, I ended up staying on Capistrano 2 and created a different solution with a single limitation -- only run against one role at a time.
