Allow no value to be a regular expression

[Trott]

That would be a good enhancement. of all the remark-lint plugins I used over the last couple of days, this is the most useful and fun to use! I wrote a rule for contractions and thought the same - using the group would be useful there. E.g. { no: "\\w+'ll", yes: '$1 will' } to "they'll" => "they will". In a related matter, I couldn't enter "no" regex directly (had to be a string). I was trying to do a negative look behind /(?<!foo)bar/i, but the plugin does string manipulation on the rule and it screws up the expression. It's not clear the rules must be strings, but it'd be nice if they didn't have to be.
