Usage

import TextEditorPlus

struct ContentView: View {
    @State var text = """
    Hello World
    """
    @State var isEditable = true
    var body: some View {
        TextEditorPlus(text: $text)
            .textSetting(isEditable, for: .isEditable)
    }
}

Set text weight and size:

TextEditorPlus(text: $text)
    .font(.systemFont(ofSize: 24, weight: .regular))

Set editor padding:

TextEditorPlus(text: $text)
  .textSetting(23, for: .insetPadding)

Set editor background color:

TextEditorPlus(text: $text)
  .textSetting(NSColor.red, for: .backgroundColor)

Set editor text color:

TextEditorPlus(text: $text)
  .textSetting(NSColor.red, for: .textColor)

Set editor placeholder string:

TextEditorPlus(text: $text)
    //.font(NSFont(name: "pencontrol", size: 12)!)
    .font(.systemFont(ofSize: CGFloat(Float(fontSize)!), weight: .regular))
    .textSetting("Test placeholder string", for: .placeholderString)

Manipulate attributed strings with attributes such as visual styles, hyperlinks, or accessibility data for portions of the text.

TextEditorPlus(text: $text)
    .textSetting(isEditable, for: .isEditable)
    .textViewAttributedString(action: { val in
            let style = NSMutableParagraphStyle()
            style.lineSpacing = 5
            style.lineHeightMultiple = 1.2
            val.addAttribute(.paragraphStyle, value: style, range: NSRange(location: 0, length: val.length))
            return val
    })

NSMutableAttributedString Support

You can now use TextEditorPlus with NSMutableAttributedString for more advanced text formatting:

import TextEditorPlus

struct ContentView: View {
    @State var attributedText = NSMutableAttributedString(string: """
        This is an example of NSMutableAttributedString.
        You can apply rich text formatting directly!
        """)
    
    var body: some View {
        VStack {
            // Using NSMutableAttributedString binding
            TextEditorPlus(text: $attributedText)
                .textSetting(true, for: .isEditable)
                .onAppear {
                    setupAttributedText()
                }
            
            Button("Add Formatting") {
                applyFormatting()
            }
        }
    }
    
    func setupAttributedText() {
        let fullRange = NSRange(location: 0, length: attributedText.length)
        
        // Set base font
        #if os(iOS)
        attributedText.addAttribute(.font, value: UIFont.systemFont(ofSize: 16), range: fullRange)
        #else
        attributedText.addAttribute(.font, value: NSFont.systemFont(ofSize: 16), range: fullRange)
        #endif
        
        // Apply paragraph style
        let paragraphStyle = NSMutableParagraphStyle()
        paragraphStyle.lineSpacing = 3
        paragraphStyle.paragraphSpacing = 8
        attributedText.addAttribute(.paragraphStyle, value: paragraphStyle, range: fullRange)
    }
    
    func applyFormatting() {
        let highlightText = "NSMutableAttributedString"
        let range = (attributedText.string as NSString).range(of: highlightText)
        if range.location != NSNotFound {
            #if os(iOS)
            attributedText.addAttribute(.backgroundColor, value: UIColor.systemBlue, range: range)
            attributedText.addAttribute(.foregroundColor, value: UIColor.white, range: range)
            #else
            attributedText.addAttribute(.backgroundColor, value: NSColor.systemBlue, range: range)
            attributedText.addAttribute(.foregroundColor, value: NSColor.white, range: range)
            #endif
        }
    }
}

The TextEditorPlus now supports both String and NSMutableAttributedString bindings:

• TextEditorPlus(text: $text) - for String binding
• TextEditorPlus(text: $attributedText) - for NSMutableAttributedString binding

When using NSMutableAttributedString, the text view will preserve all formatting attributes and allow direct manipulation of the attributed string.
