Ticket #206: sample_expansion_syntax.yml

# Of course, if expansion was possible using anchors and tags, it would
# logically make sense to be able to anchor an item that is itself referencing
# another item, in order to chain expansions.
#
# A simulated real-world example:

database_pool:
  - &default
    host:   10.10.10.1
    port:   53000
    user:   my_user
    passwd: S3kr1t
    db:     my_db
  - *default &secondary
    host:   10.10.10.2
  - *secondary
    port:   53001
    
# Theoretically, the above would expand to this (JSON):

{
  "database_pool": [
    {
      "passwd": "S3kr1t", 
      "host":   "10.10.10.1", 
      "db":     "my_db", 
      "port":   53000, 
      "user":   "my_user"
    }, 
    {
      "passwd": "S3kr1t", 
      "host":   "10.10.10.2", 
      "db":     "my_db", 
      "port":   53000, 
      "user":   "my_user"
    }, 
    {
      "passwd": "S3kr1t", 
      "host":   "10.10.10.2", 
      "db":     "my_db", 
      "port":   53001, 
      "user":   "my_user"
    }
  ]
}
