How can we apply multiple styles to same string using regex pattern? about swiftrichstring HOT 2 CLOSED

Happy to see this.

Thanks

Hi,
With 0.9.9 I've introduced a new function to String instances called func set(regExpStyles: [RegExpPatternStyles], default dStyle: Style? = nil) -> NSMutableAttributedString.
This function accepts:

• an array of RegExpPatternStyles objects. A single RegExpPatternStyles is a struct which defines a regular expression and an array of Styles to apply when found.
• a default Style: optional, if specified this style is applied before any other regular expression, to the entire string.

Following your request we can, for example, define two regular expression to search email and urls in a string:

let regexp_url = "http?://([-\\w\\.]+)+(:\\d+)?(/([\\w/_\\.]*(\\?\\S+)?)?)?"
let regexp_email = "([A-Za-z0-9_\\-\\.\\+])+\\@([A-Za-z0-9_\\-\\.])+\\.([A-Za-z]+)"

and defines two styles to apply when regexp did match:

let style_email = RegExpPatternStyles(pattern: regexp_email) {
  $0.color = .red
}!
		
let style_url = RegExpPatternStyles(pattern: regexp_url) {
  $0.color = .blue
}!

Then:

let text_example = "My email is [email protected] and my website is http://www.danielemargutti.com"
var result = text_example.set(regExpStyles: [style_email, style_url])

Will produce this:

0.9.9 will be released soon.
Thank you for your suggestion.
Have a nice day.
