What do you think of providing a method of extracting time(s) from a Locator
There is a private extension on Locator which kind of does this, but looks like it only matches start time (my understanding is that end time can be specified).
|
private extension Locator { |
|
private static let timeFragmentRegex = try! NSRegularExpression(pattern: #"t=(\d+(?:\.\d+)?)"#) |
|
|
|
// FIXME: Should probably be in `Locator` itself. |
|
func time(forDuration duration: Double? = nil) -> Double? { |
|
if let progression = locations.progression, let duration = duration { |
|
return progression * duration |
|
} else { |
|
for fragment in locations.fragments { |
|
let range = NSRange(fragment.startIndex ..< fragment.endIndex, in: fragment) |
|
if let match = Self.timeFragmentRegex.firstMatch(in: fragment, range: range) { |
|
let matchRange = match.range(at: 1) |
|
if matchRange.location != NSNotFound, let range = Range(matchRange, in: fragment) { |
|
return Double(fragment[range]) |
|
} |
|
} |
|
} |
|
} |
|
return nil |
|
} |
|
} |
Would you be open to a Locator.time property/function (() -> (Double?, Double?)?). I'd be open to providing a PR for this if you want.
