An extractor object that yields the groups in the match.
An extractor object that yields the groups in the match. Using this extractor rather than the original Regex
ensures that the match is not recomputed.
import scala.util.matching.Regex.Groups
val date = """(\d\d\d\d)-(\d\d)-(\d\d)""".r
val text = "The doc spree happened on 2011-07-15."
val day = date replaceAllIn(text, _ match { case Groups(_, month, day) => s"$month/$day" })

Groups.type
An extractor object for Matches, yielding the matched string.
An extractor object for Matches, yielding the matched string.
This can be used to help writing replacer functions when you are not interested in match data. For example:
import scala.util.matching.Regex.Match
"""\w+""".r replaceAllIn ("A simple example.", _ match { case Match(s) => s.toUpperCase })

class Matchclass MatchIterator
A class to step through a sequence of regex matches.
A class to step through a sequence of regex matches.
This is an iterator that returns the matched strings.
Queries about match data pertain to the current state of the underlying matcher, which is advanced by calling hasNext
or next
.
When matches are exhausted, queries about match data will throw java.lang.IllegalStateException.

Concrete methods
Quotes strings to be used literally in regex patterns.
Quotes strings to be used literally in regex patterns.
All regex metacharacters in the input match themselves literally in the output.

-
List("US$", "CAN$").map(Regex.quote).mkString("|").r

Quotes replacement strings to be used in replacement methods.
Quotes replacement strings to be used in replacement methods.
Replacement methods give special meaning to backslashes (\
) and dollar signs ($
) in replacement strings, so they are not treated as literals. This method escapes these characters so the resulting string can be used as a literal replacement representing the input string.
Value parameters
- text
-
The string one wishes to use as literal replacement.
Attributes
- Returns
-
A string that can be used to replace matches with
text
. - Example
-
"CURRENCY".r.replaceAllIn(input, Regex quoteReplacement "US$")
