named-regexp 0.1.6

This library is a wrapper for java.util.regex, implementing named capture groups for Java 5/6. Note this isn't needed in Java 7, which already supports this feature.

This is a fork of the named-regexp project that fixes several bugs.

Usage

1. Replace java.util.regex.Pattern and java.util.regex.Matcher with NamedPattern and NamedMatcher, respectively.
2. Use (?<name>...) to specify a named capture group as in the following code example:

public static void main(String[] args) {
	String input = "hello world!";
	String regex = "(?<foo>world)"; // contains capture group named "foo"
	boolean found;
	
	NamedPattern pattern = NamedPattern.compile(regex);
	NamedMatcher matcher = pattern.matcher(input);
	
	found = matcher.find();
	System.out.println("Input: " + input);
	System.out.println("Regex: " + regex);
	System.out.println("Found: " + found);

	if (found) {
		System.out.println("Captured: " + matcher.group("foo"));
	}
}
