[feature request] ability to not install a system ruby version? about rbenv HOT 6 OPEN

@thom-nic can you show content of your .ruby-version file?

from rbenv.

It's just a single line:

2.1.3

Rbenv already understands how to process it, it's sort of a generic .rbenv-version file. I just go to the root directory of your project and do rbenv install. rbenv also knows which ruby version to activate when running project executables (ruby, rake) by looking at the same file.

@thom-nic do you need to override ruby version from default 2.2.0 to your 2.1.3?

from rbenv.

As can you see in Readme - you can setup any ruby with this role.

- hosts: all
  vars:
    rbenv:
      env: user
      version: v0.4.0
      ruby_version: 2.0.0-p353
  roles:
    - role: zzet.rbenv
      rbenv_users:
        - user

as example

Yeah I understand I can set it up that way but I still have to specify the ruby version there in addition to what's in my project .ruby-version. rbenv's ruby shim will throw an error if what's in .ruby-version is different from what's defined in the ansible vars. Trying to keep it DRY and reduce the chance for errors.

Simply not installing a system ruby until the app is installed would fix that. I mean I can run rbenv install regardless after my app is installed and to ensure the proper ruby version is installed for my app but it will increase the build/ deploy time if two different rubies get installed.

👍 it would be great to have an option to skip installing a Ruby and just set up rbenv instead.
