Hi,

I thought the following should work, but I got a syntax error. Can the yml condition check syntax be used inside with\_items? If not, how can I generate a dynamic list in the role to be used by with\_items (register ??)? Thank you very much and appreciate any clues to fix following statement or workarounds.

- name: install scripts  
copy: dest={{ home }}/scripts/{{ item }} src=scripts/{{ item }} mode=755  
with\_items:  
{% set script\_list = %}  
{% for s in services %}  
{% for g in s.groups %}  
{% if g in groups %}  
{% if script\_list.append(s.script) %}  
{% endif %}  
{% endif %}  
{% endfor %}  
{% endfor %}  
{% for script in script\_list | unique %}  
{{ script }}  
{% endif %}

Forgot the error message:

Note: The error may actually appear before this position: line 17, column 6

with\_items:  
{% set script\_list = %}

Also fixed the list line:

{% for script in script\_list | unique %}  
{{ script }}  
{% endfor %}

Don’t worry about it, don’t need it any more.

Thank you.
