Thanks. That’s handy, but I’m not likely to remember it (regex not my thing), whereas an action can be named and easily run.
I’ve been thinking about this for while. It’s similar to other Drafts actions I’ve written, so I took some of that code and built [this](https://actions.getdrafts.com/a/17N).
"""#
let stringRange = NSRange(location: 0, length: testString.utf16.count)
let matches = regex.matches(in: testString, range: stringRange)
var result: [[String]] = []
for match in matches {
var groups: [String] = []
for rangeIndex in 1 ..< match.numberOfRanges {
let nsRange = match.range(at: rangeIndex)
guard !NSEqualRanges(nsRange, NSMakeRange(NSNotFound, 0)) else { continue }
let string = (testString as NSString).substring(with: nsRange)
groups.append(string)
}
if !groups.isEmpty {
result.append(groups)
}
}
print(result)
