class Regex extends Serializable

A regular expression is used to determine whether a string matches a pattern and, if it does, to extract or transform the parts that match.

Usage

This class delegates to the java.util.regex package of the Java Platform. See the documentation for java.util.regex.Pattern for details about the regular expression syntax for pattern strings.

An instance of Regex represents a compiled regular expression pattern. Since compilation is expensive, frequently used Regexes should be constructed once, outside of loops and perhaps in a companion object.

The canonical way to create a Regex is by using the method r, provided implicitly for strings:

val date = raw"(\d{4})-(\d{2})-(\d{2})".r

Since escapes are not processed in multi-line string literals, using triple quotes avoids having to escape the backslash character, so that "\\d" can be written """\d""". The same result is achieved with certain interpolators, such as raw"\d".r or a custom interpolator r"\d" that also compiles the Regex.

Extraction

To extract the capturing groups when a Regex is matched, use it as an extractor in a pattern match:

"2004-01-20" match {
  case date(year, month, day) => s"$year was a good year for PLs."
}

To check only whether the Regex matches, ignoring any groups, use a sequence wildcard:

"2004-01-20" match {
  case date(_*) => "It's a date!"
}

That works because a Regex extractor produces a sequence of strings. Extracting only the year from a date could also be expressed with a sequence wildcard:

"2004-01-20" match {
  case date(year, _*) => s"$year was a good year for PLs."
}

In a pattern match, Regex normally matches the entire input. However, an unanchored Regex finds the pattern anywhere in the input.

val embeddedDate = date.unanchored
"Date: 2004-01-20 17:25:18 GMT (10 years, 28 weeks, 5 days, 17 hours and 51 minutes ago)" match {
  case embeddedDate("2004", "01", "20") => "A Scala is born."
}
Find Matches

To find or replace matches of the pattern, use the various find and replace methods. For each method, there is a version for working with matched strings and another for working with Match objects.

For example, pattern matching with an unanchored Regex, as in the previous example, can also be accomplished using findFirstMatchIn. The findFirst methods return an Option which is non-empty if a match is found, or None for no match:

val dates = "Important dates in history: 2004-01-20, 1958-09-05, 2010-10-06, 2011-07-15"
val firstDate = date.findFirstIn(dates).getOrElse("No date found.")
val firstYear = for (m <- date.findFirstMatchIn(dates)) yield m.group(1)

To find all matches:

val allYears = for (m <- date.findAllMatchIn(dates)) yield m.group(1)

To iterate over the matched strings, use findAllIn, which returns a special iterator that can be queried for the MatchData of the last match:

val mi = date.findAllIn(dates)
while (mi.hasNext) {
  val d = mi.next
  if (mi.group(1).toInt < 1960) println(s"$d: An oldie but goodie.")
}

Although the MatchIterator returned by findAllIn is used like any Iterator, with alternating calls to hasNext and next, hasNext has the additional side effect of advancing the underlying matcher to the next unconsumed match. This effect is visible in the MatchData representing the "current match".

val r = "(ab+c)".r
val s = "xxxabcyyyabbczzz"
r.findAllIn(s).start    // 3
val mi = r.findAllIn(s)
mi.hasNext              // true
mi.start                // 3
mi.next()               // "abc"
mi.start                // 3
mi.hasNext              // true
mi.start                // 9
mi.next()               // "abbc"

The example shows that methods on MatchData such as start will advance to the first match, if necessary. It also shows that hasNext will advance to the next unconsumed match, if next has already returned the current match.

The current MatchData can be captured using the matchData method. Alternatively, findAllMatchIn returns an Iterator[Match], where there is no interaction between the iterator and Match objects it has already produced.

Note that findAllIn finds matches that don't overlap. (See findAllIn for more examples.)

val num = raw"(\d+)".r
val all = num.findAllIn("123").toList  // List("123"), not List("123", "23", "3")
Replace Text

Text replacement can be performed unconditionally or as a function of the current match:

val redacted    = date.replaceAllIn(dates, "XXXX-XX-XX")
val yearsOnly   = date.replaceAllIn(dates, m => m.group(1))
val months      = (0 to 11).map { i => val c = Calendar.getInstance; c.set(2014, i, 1); f"$c%tb" }
val reformatted = date.replaceAllIn(dates, _ match { case date(y,m,d) => f"${months(m.toInt - 1)} $d, $y" })

Pattern matching the Match against the Regex that created it does not reapply the Regex. In the expression for reformatted, each date match is computed once. But it is possible to apply a Regex to a Match resulting from a different pattern:

val docSpree = """2011(?:-\d{2}){2}""".r
val docView  = date.replaceAllIn(dates, _ match {
  case docSpree() => "Historic doc spree!"
  case _          => "Something else happened"
})

Instance Constructors

  1. new Regex(regex: String, groupNames: String*)

    Compile a regular expression, supplied as a string, into a pattern that can be matched against inputs.

    Compile a regular expression, supplied as a string, into a pattern that can be matched against inputs.

    If group names are supplied, they can be used this way:

    val namedDate  = new Regex("""(\d\d\d\d)-(\d\d)-(\d\d)""", "year", "month", "day")
    val namedYears = for (m <- namedDate findAllMatchIn dates) yield m group "year"

    Group names supplied to the constructor are preferred to inline group names when retrieving matched groups by name. Not all platforms support inline names.

    This constructor does not support options as flags, which must be supplied as inline flags in the pattern string: (?idmsux-idmsux).

    regex

    The regular expression to compile.

    groupNames

    Names of capturing groups.

  2. final def ##(): Int

    Equivalent to x.hashCode except for boxed numeric types and null.

    Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

  7. final def asInstanceOf[T0]: T0

    Cast the receiver object to be of type T0.

    Cast the receiver object to be of type T0.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

  13. final def eq(arg0: AnyRef): Boolean

    Tests whether the argument (that) is a reference to the receiver object (this).

    Tests whether the argument (that) is a reference to the receiver object (this).

    The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

    • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
    • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
    • null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    true if the argument is a reference to the receiver object; false otherwise.

  16. def findAllIn(source: CharSequence): MatchIterator

    Return all non-overlapping matches of this Regex in the given character sequence as a scala.util.matching.Regex.MatchIterator, which is a special scala.collection.Iterator that returns the matched strings but can also be queried for more data about the last match, such as capturing groups and start position.

    Return all non-overlapping matches of this Regex in the given character sequence as a scala.util.matching.Regex.MatchIterator, which is a special scala.collection.Iterator that returns the matched strings but can also be queried for more data about the last match, such as capturing groups and start position.

    A MatchIterator can also be converted into an iterator that returns objects of type scala.util.matching.Regex.Match, such as is normally returned by findAllMatchIn.

    Where potential matches overlap, the first possible match is returned, followed by the next match that follows the input consumed by the first match:

    val hat  = "hat[^a]+".r
    val hathaway = "hathatthattthatttt"
    val hats = hat.findAllIn(hathaway).toList                     // List(hath, hattth)
    val pos  = hat.findAllMatchIn(hathaway).map(_.start).toList   // List(0, 7)

    To return overlapping matches, it is possible to formulate a regular expression with lookahead (?=) that does not consume the overlapping region.

    val madhatter = "(h)(?=(at[^a]+))".r
    val madhats   = madhatter.findAllMatchIn(hathaway).map {
      case madhatter(x,y) => s"$x$y"
    }.toList                                       // List(hath, hatth, hattth, hatttt)

    Attempting to retrieve match information after exhausting the iterator results in java.lang.IllegalStateException. See scala.util.matching.Regex.MatchIterator for details.

    Create a new Regex with the same pattern, but no requirement that the entire String matches in extractor patterns.

    Create a new Regex with the same pattern, but no requirement that the entire String matches in extractor patterns.

    Normally, matching on date behaves as though the pattern were enclosed in anchors, "^pattern$".

    The unanchored Regex behaves as though those anchors were removed.

    Note that this method does not actually strip any matchers from the pattern.

    Calling anchored returns the original Regex.

  41. def unapplySeq(c: Char): Option[List[Char]]

    Tries to match the String representation of a scala.Char.

    Tries to match the String representation of a scala.Char.

    If the match succeeds, the result is the first matching group if any groups are defined, or an empty Sequence otherwise.

    // the case must consume the group to match
    val r = """(\p{Lower})""".r
    cat(0) match { case r(x) => true }
    cat(0) match { case r(_) => true }
    cat(0) match { case r(_*) => true }

  42. def unapplySeq(s: CharSequence): Option[List[String]]

    Tries to match a java.lang.CharSequence.

    Tries to match a java.lang.CharSequence.

    If the match succeeds, the result is a list of the matching groups (or a null element if a group did not match any input). If the pattern specifies no groups, then the result will be an empty list on a successful match.

    This method attempts to match the entire input by default; to find the next matching subsequence, use an unanchored Regex.

    For example:

    val p1 = "ab*c".r
    val p1Matches = "abbbc" match {
      case p1() => true               // no groups
      case _    => false
    }
    val p2 = "a(b*)c".r
    val p2Matches = "abbbc" match {
      case p2(_*) => true             // any groups
      case _      => false
    }
    val numberOfB = "abbbc" match {
      case p2(b) => Some(b.length)    // one group
      case _     => None
    }
    val p3 = "b*".r.unanchored
    val p3Matches = "abbbc" match {
      case p3() => true               // find the b's
      case _    => false
    }
    val p4 = "a(b*)(c+)".r
    val p4Matches = "abbbcc" match {
      case p4(_*) => true             // multiple groups
      case _      => false
    }
    val allGroups = "abbbcc" match {
      case p4(all @ _*) => all mkString "/" // "bbb/cc"
      case _            => ""
    }
    val cGroup = "abbbcc" match {
      case p4(_, c) => c
      case _        => ""
    }
