Output from "fail" too verbose

[Uwe Sauter]

Hi all,

I have a list of files where I need to check existence and fail if one doesn't exist.

I'd expect the fail module to *just* output the defined message when the condition is true
but instead the complete item is printed.

Is there a way to make the output less verbose (but keep msg)?

Thanks,

Uwe

That's because of the with_items loop and not fail module.

You could write you own callback plugin, then you can get any format you
want, or drop loop and do it with Jinja template instead.

Try this

- fail:
msg: Files not found {{ ', '.join(r.results |
rejectattr('stat.exists') | map(attribute='item') | list) }}
when: r.results | rejectattr('stat.exists') |
map(attribute='item') | list | length > 0

Thanks, that worked. Though it feels unusual and a little like cheating Ansible.

Regards,

Uwe
