Rearrange

Rearrange is a collection of utilities for making it easier to work with NSRange and NSTextRange. It's particularly handy when used with the Cocoa text system.

Integration

Swift Package Manager:

dependencies: [
    .package(url: "https://github.com/ChimeHQ/Rearrange")
]

Types

RangeMutation

This is a struct that encapsulates a single change to an NSRange. It's useful for serializing, queuing, or otherwise storing changes and applying them.

You can also use this class to tranform individual points or other NSRanges. This is handy for updating a set of stored NSRanges as text is changed. This might seem easy, but there are a large number of edge cases that RangeMutation handles, including mutations that invalidate (for example completely delete) a range.

Extensions

NSRange

// convenience
static var zero: NSRange
static var notFound: NSRange
var max: Int

// shifting
public func shifted(by delta: Int) -> NSRange?
public func shifted(startBy delta: Int) -> NSRange?
public func shifted(endBy delta: Int) -> NSRange?

// mutating
public func clamped(to limit: Int) -> NSRange

func apply(_ change: RangeMutation) -> NSRange?

// creating
init(_ textRange: NSTextRange, provider: NSTextElementProvider)
init?(_ textRange: UITextRange, textView: UITextView)

// working with Swift String
func range(in string: String) -> Range<String.Index>?

NSTextRange

// creating
convenience init?(_ range: NSRange, provider: NSTextElementProvider)
convenience init?(_ offset: Int, provider: NSTextElementProvider)

UITextRange

// creating
convenience init?(_ range: NSRange, provider: NSTextElementProvider)

IndexSet

mutating func insert(range: NSRange)
mutating func insert(ranges: [NSRange])
mutating func remove(integersIn range: NSRange)
var nsRangeView: [NSRange]
func contains(integersIn range: NSRange) -> Bool
func intersects(integersIn range: NSRange) -> Bool
var limitSpanningRange: NSRange?

String

subscript(range: Range<Int>) -> Substring?
subscript(range: NSRange) -> Substring?
