@Josiah : Thanks for the tip, I didn't know about the ||= operator.

I was looking for a way to do that using the attribute files.

Based on your response, my new work around is to define the component's attributes in two different hashes and have them merge into the default one.

Thanks

I would set this in the component's recipe:

node.normal[:myapp][:part1][:conf] ||= "XXX1"

||= will only set the attribute if the attribute has not yet been set.

Ohai Chefs !

Is there a way in an attribute file to reuse attributes from another file ?

Here is my use case :

I have an application split in two components, each requiring its configuration.

Most of thetime the configuration of both will be identical but this may not be always true.

For this reason I'd like to define 'default' attributes in the default attribute file and then have one attribute file per part of my application. Atribute would be organized this way :

default.rb

  default["myapp"]["conf"] = "XXX"

  default["myapp"]["truc"] = "YYY"
part1.rb
  default["myapp"]["part1"]["conf"] = "XXX1"
  #default["myapp"]["part1"]["truc"] = "YYY" < I want it to default to this value when not explicitly set
part2.rb
  default["myapp"]["part2"]["conf"] = "XXX2"

Is there a way to achieve this ?

At the moment I am using global variable to pass information from one file to the other but this seams ugly to me.

Split the shared part out into another cookbook?
