Tweak wildcard variable handling

[myllynen]

Currently wildcard vars are handled like

lookup('ansible.builtin.varnames', 'gateway_settings.*'))

which works but causes duplicated items e.g. with the following defined:

gateway_settings
gateway_settings_test

Tweaking the parameter to be

lookup('ansible.builtin.varnames', 'gateway_settings_.*'))

would solve this issue and allow both of the above work together or independently.

The only potential downside would be that variables like

gateway_settingstest

wouldn't be accepted anymore but that seem more like a good thing.

What do you think, would a PR for this be acceptable? Thanks.

It might be best to use this format:

lookup('ansible.builtin.varnames', '^gateway_settings_.*'))

as otherwise something like todo_gateway_settings_test would not be ignored.

For settings it should be dict combine. I am working on also adding functionality to ensure it's unique but I haven't finished testing it yet. I should be opening a PR soon

[djdanielsson]

Good point on the regex lookup though I will look to add that to all of them

Thanks for looking into this.

Perhaps you could also consider these ideas while at it, I'll leave it up to you to determine whether to actually use them or not:

1. Using query() instead of lookup() would allow for more compact code for loop
2. Given that it is possible to use variables also on the left-hand side with set_fact it might be possible to use just one task with product() and/or inline jinja but the resulting code might not be somewhat hard to read
