TextViewPlus is a collection of utilities for making it easier to work with
Swift Package Manager:
dependencies: [ .package(url: "https://github.com/ChimeHQ/TextViewPlus.git") ]
Wrappers around the underlying
NSLayoutManager, but with a much more convenient API.
func enumerateLineFragments(for range: NSRange, block: (NSRect, NSRange) -> Void) func enumerateLineFragments(for rect: NSRect, block: (NSRect, NSRange) -> Void)
Handy methods for computing ranges of text within the view.
func textRange(for rect: NSRect) -> NSRange var visibleTextRange: NSRange
Convenience methods for computing selection ranges/locations.
var selectedTextRanges: [NSRange] var selectedContinuousRange: NSRange? var insertionLocation: Int?
Styling changes can be very expensive, this method is much faster in certain common cases.
func updateFont(_ newFont: NSFont, color newColor: NSColor)
Computing bounding rectangles of displayed text.
func boundingRect(for range: NSRange) -> NSRect? func boundingRect(forGlyphRange range: NSRange) -> NSRect? func boundingSelectionRects(forRange range: NSRange) -> [NSRect]
Programmtic modification of the underlying attributed string in the
NSTextStorage, with support for delegate callbacks and undo.
func replaceCharacters(in range: NSRange, with attributedString: NSAttributedString) // with undo supported func replaceString(in range: NSRange, with attributedString: NSAttributedString)
NSTextView behaviors can be tricky, and often involve complex interactions with the whole system (
public var wrapsTextToHorizontalBounds: Bool
// Fixes a widely-seen selection drawing artifact func applySelectionDrawingWorkaround()
