Groovy: Find Operator (=~)

Find (=~) operator is used to get an instance of java.util.regex.Matcher.

HelloWorld.groovy

def text = "aaaab"
def matcher = text =~ /a*b/  

matcher.matches()

println "I found the text " + matcher.group()
println "Starting at index " + matcher.start()
println "Ending at index " + matcher.end()

Output

I found the text aaab
Starting at index 0
Ending at index 4

def matcher = text =~ /a*b/

=~ creates a matcher against the text variable, using the pattern on the right-hand side. Return type of =~ is a Matcher
