Hello,  
I would like to change a file based on the lower case of a variable.  
How do I do that?  
I tried

- name: replace string in file

replace: dest=‘{{base\_dir}}/{{lower(attribute\_name)}}.file.properties’ regexp=‘CHANGEME’ replace=‘{{ ansible\_fqdn }}’ backup=yes

I thought I would be able to do it as in Jinja but that doesn’t work.  
Any idea?  
Antoine
