SwiftyFormat

SwiftyFormat - string formatter library with simple format syntax #{{key|default value|prefix|suffix}}.

1. key (required) is used for identifying parameter inside mapping
2. default value (optional) this value is used when mapping returns nil for key
3. prefix (optional) is added before value. Not added for default value
4. suffix (optional) is added after value. Not added for default value

Example

let format = "#{{user}} mentioned you in a comment. #{{comment}}"
let result = NSAttributedString(format: format, mapping: ["user": "Jack", "comment": "How are you Jill?"])

Closure can be passed instead of dictionary. It is useful, when format can be changed, and not all parameters required for every format.

let result = NSAttributedString(format: someFormat) { key in
   switch key {
   case "name":
      return NSAttributedString(string: "Jack", attributes: nameAttributes)
   case "cookies":
      return cookies
   default:
      return nil
   }
}

You can also specify default value, prefix and suffix

let format = #"#{{user}} mentioned you in a comment#{{comment|| "|"}}"#
let result1 = NSAttributedString(format: format, mapping: [:])
//result1 == Your friend mentioned you in a comment
let result2 = NSAttributedString(format: format, mapping: ["name": "Jack", comment: "How are you?"])
//result2 == Jack mentioned you in a comment "How are you?"

Same format syntax can be used for String

let format = "#{{user}} mentioned you in a comment. #{{comment}}"
let result = String(format: format, mapping: ["user": "Jack", "comment": "How are you Jill?"])
