Mostly i was thinking for the use of in templates, the only other
thing i can think of is using 'intermediate vars' to keep reusable
expressions and then creating their input when needed:
- play:
vars:
merged_list: "{{ (lookup('vars', *query('varnames',
merge_pattern$')) + [testlist_initial_value]) |
flatten(levels=merge_flatten_levels|default(1)) }}"
....
- name: also works with 'vars' in other scopes, using set_fact to
get 'static value'
set_fact:
mylist: '{{merged_list}}'
vars:
testlist_initial_value: [10,11]
merge_pattern: '^.+_merge_list'
a_merge_list: [1,2,3]
b_merge_list: [4,5,6]
