A wrapper for running app installer/un-installers, etc.

a_sample_usage.rb

# An example usage might look something like:

class MyApp
  extend Verver::SandboxedExecute

  def initialize(options)
    # ...
  end

  # ...

  def install!
    # run the installer for this kind of app
  end

  def uninstall!
    # run the uninstaller for this kind of app
  end
end



MyApp.execute(foo: 'blah', this: 'that') do |instance|
  # do interesting things w/the app here.
end

sandboxed_execute.rb

# Is this a really bad idea? Specifically, the private method bit?
# Also, any thoughts on the API?

module Verver
  module SandboxedExecute

    def execute(install_options={}, &safe_block)
      instance = new(install_options)
      return unless instance.install!

      __execute_in_sandbox(instance, safe_block)
    end

    private

    def __execute_in_sandbox(instance, safe_block)
      safe_block.call(instance)
    ensure
      instance.uninstall!
    end

  end
