Re: [ansible-project] Default filter issue
This could work, but only if there is no such group. When the group exists,
but its empty, it throws error.

You should be able to use: groups.examples.0 | default(...)
This is the one case where dot notation is simpler/better :)

I suppose you have to accommodate the case where there is no examples entry in
"groups" (untested):
{% if 'examples' in groups %}groups['examples'][0] | default('localhost'){%
else %}localhost{% endif %}

[ansible-project] Default filter issue
Hello,
Im trying to use default filter:
hosts: ["{{ groups['examples'][0] | default('localhost') }}":5045]
But it return error:
FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'dict
object' has no attribute 'examples'"}.
I read something about default can use only 1 level deep, but I cannot
write more levels properly.
