conditional require

[Kenneth Lo]

On a vanilla resource require statement, is there a way to define a require for either 'resource A' or 'resource B' ?

Historically our system setup increment app per version (as opposed to having a parameter to define it). Ie. Say, we have a tomcat_6 and tomcat_7 classes for tomcat v.6 and v.7 respectively. So obviously if some other resources is depending on Tomcat, a particular node would have either 6 or 7. 

Note that we have not yet utilize fact for version documentation. Thanks in advance.

Not directly, no.  What you can do is create, apply, and set your requirement for a class of this general form:

class tomcat {
  if $i_want_tomcat_6 {
    include 'tomcat_6'
  } else {
    include 'tomcat_7'
  }
}
