sorry for the mess, but the previous replies was wrong..
it's important to keep no space between different lines:
- hosts: servers
#gather_facts: false
roles:
- role: myrole1
vars:
confobjs: "{% set objs = {} %}\
{% if confobj1 is defined %}\
{% set objs1 = objs|combine({'confobj1': confobj1}) %}\
{% set objs = objs1 %}\
{% endif %}\
{% if confobjn is defined %}\
{% set objs1 = objs|combine({'confobjn': confobjn}) %}\
{% set objs = objs1 %}\
{% endif %}\
{{ objs }}"
in the task:
#not yet working in ansible release 2.3.2
# when: lookup('vars', item|basename, default=false)
#workaround see role variable confobjs in the playbook launcher
when: confobjs[item|basename] is defined
register: template_result
it seems to work ugly well
