String Extension of Regular Expression 简体中文
This project provides a light weight / simple regular expression extension for Swift String.
This package builds with Swift Package Manager and is part of the Perfect project. It was written to be stand-alone and so does not require PerfectLib or any other components.
Ensure you have installed and activated the latest Swift 4.0 tool chain.
Add this project as a dependency in your Package.swift file.
.package(url:"https://github.com/PerfectSideRepos/Perfect-RegEx.git", from: "3.1.0")
...
dependencies: ["RegEx"]
Then please add the following line to the beginning part of swift sources:
import Regex
The following demo shows how to extract substring ranges with a pattern:
var source = "there is a bloody bad bread on my bed."
let ranges = source.match(pattern: "b[a-z]+d")
// it will figure out the range of `blood`, `bad` `bread` and `bed`
// you can do further operations, such as remove:
source.removeSubrange(ranges[0])
print(source)
// the result should be:
// there is a y bad bread on my bed.
extension String {
/// test if the string contains certain pattern
/// - parameters:
/// - pattern: string to recognize
/// - return: true for found
public func contains(pattern: String) -> Bool
/// find string ranges
/// - parameters:
/// - pattern: string to recognize
/// - return: a string range array
public func match(pattern: String) -> [Range<String.Index>]
}
