VSCode Style/PercentLiteralDelimiters rule not being respected in ruby files - ruby

Question

Please help me I am being tortured by the linting squiggly and I cannot get rid of it. Here is the context
working in vscode 1.37.0
on a chef project (mostly ruby syntax)
I have the chef extension installed and chefdk installed an available in my path
And for the life of me I cannot get the linting warning for Style/PercentLiteralDelimiters to go away. I will get this warning when I am using []
Then if I make the suggested change to () it wants me to flip it the other way.
I get the same results if I specify this rule in my rubocop.yml
Style/PercentLiteralDelimiters:
Enabled: true
PreferredDelimiters:
default: '[]'
I know this is an obscure issue and if there is any further information that would help I will be happy to supply it but for my sanity I would really like to figure this out.
Update
Running rubocop from the command line does not report any issue. I believe that vscode is using chefdk's foodcritic. As according to the extension If you have the ChefDK installed, Foodcritic should "just work" on Windows. My understanding is foodcritic is just rubocop with a special config for chef style conventions. But even running foodcritic from the command line does not seem to report these as an issue.
I have even tried to be explicit in the vscode workspace settings, by setting the configFile path for both rubocop and foodcritic but this has not changed anything. Seems more and more like an issue the extension. Found this issue that sounds related. Might just have to watch this issue https://github.com/pendrica/vscode-chef/issues/29

Answer 1

So thanks to the comment from Draco Alter I was able to figure out the issue I had.
First I had a miss understanding about Foodcritic and was conflating it with cookstyle. After understanding that and the comment that Draco made saying
Some of the rules in Cookstyle and Rubocop are conflicting - and %w
is one of them.
I figured I would favor cookstyle as I am using ruby exclusively for chef. So I ensured rubocop was gone gem uninstall rubocop and then I just needed to update my vscode workspace settings to have from
{
"ruby.lint": {
-- "rubocop": true
++ "cookstyle": true
}
}
