How to Extend Existence to Error Out on Contractions

[kayx23]

Here's my yaml config:

extends: existence
message: "Avoid using contractions."
level: error
match:
  - '\b(\w+\'\w+)\b'
ignore_case: true

I have other yaml files in this custom folder and they are picked up by .vale.ini. I feel like the issue might be in '\b(\w+\'\w+)\b' but can't for the heck of my life figure out where the problem is.

Any help appreciated!

Ok just saw this example where substitution is used instead of existence. Still curious to know why my config couldn't work, if somebody figures out.

Closing as I realized even if the regEx works, it is not a good idea as it would picks up words like dog's, cat's which isn't my intention. The substitution is indeed a better approach.
