WARNING: This regex currently removes ALL text in the next non-blank line following the beginning of a \"complimentaryClose\", up to 2 lines after. This may stil be too greedy.
LEAVE:
Regarding your first question...
This worked OK:
/[\\r\\n]*(?:(?:kind(?:est)* )*regards|cheers?|greetings?),?[\\t\\f ]*[\\r\\n]*\\w*(?:[,.!?: ]*|$)/gi";
// result will be an iterator over tuples containing the start and end indices for each match in the string
let result = regex.captures_iter(string);
for mat in result {
println!("{:?}", mat);
}
}
