complex-aliases.yaml

# this is an example of how to use aliases to avoid making yaml too large
# just by using language features of yaml and a parser support without
# relying on juju at all

# this was done for charm-helpers, see:
# charmhelpers/fetch/__init__.py
# def configure_sources
# and
# charmhelpers/fetch/ubuntu.py
# def add_source

# specifically, bacause charm-helpers require you to embed a yaml list
# into a bundle string parameter:
# 'Configure multiple sources from charm configuration.
# The lists are encoded as yaml fragments in the configuration.
# The fragment needs to be included as a string. Sources and their
# corresponding keys are of the types supported by add_source().'


variables:
  # an alias defined for a multi-line string, followed
  # by an actual one-item list with a multi-line item containing
  # a colon (":") which would be interpreted by the second yaml
  # parser invocation if not for '|'. In this case the colon is a part
  # of a public key, therefore, we want to ignore it for parsing.
  # Note the indentation: a string has to be on the same level as the pipe
