Attributed

µframework for Attributed strings.

What is Attributed?

Attributed aims to be a drop in replacement to the current verstion of the NSAttributedString API. The existing interface to using attributed strings has a few flaws, namely if you dont know the Key and type of value needed to set a certain attribute, you have spend time checking documentation or the reading the comments for NSAttributedString. Another concern is safety, passing a dictionary of type [String: Any] to the constructor of NSAttributedString is a potential crash at runtime waiting to happen.

By wrapping the current official interface to NSAttributedString into a fluent easy to use API, Attributed was made in an attempt to give developers an alternative option to the official interface.

Features

• Create NSAttributedString instances with a simple and fluid interface
• Combine NSAttributedStrings with +
• Partially apply Attributes to parts of an NSAttributedString by providing a Range

Usage

Creating a new NSAttributedString by closure composition

"This is not a string".at.attributed {
  return $0.foreground(color: .red)
           .font(UIFont(name: "Chalkduster", size: 24.0)!)
           .underlineStyle(.styleSingle)
}

Creating a new NSAttributedString by passing an attributes object

First create an Attributes object:

let attributes = Attributes {
    return $0.foreground(color: .red)
             .font(UIFont(name: "Chalkduster", size: 24.0)!)
             .underlineStyle(.styleSingle)
}

then simply apply the Attributes to a String:

"Hello".at.attributed(with: attributes)

Combining NSAttributedString with +

This library defines an concatenation operator + for concatentating instances of NSAttributedString. + works with NSAttributedString no different than it does for String. This can be useful for combining NSAttributedStrings with different attributes to produce the desired effect without having to specify ranges to apply different attributes to.

let bodyAttributes = Attributes { 
    return $0.foreground(color: .purple)
             .font(UIFont(name: "Noteworthy-Light", size: 20.0)!)
}

let authorAttributes = bodyAttributes.foreground(color: .black)

"I think theres something strangely musical about noise.".at.attributed(with: bodyAttributes)
+ "\n  - Trent Reznor".at.attributed(with: authorAttributes)
