Will be interpreted as an escape character and can be used to escape theĭollar sign. Interpreted as a reference to a group in the matched pattern, with numbersġ through 9 corresponding to the first nine groups, and 0 standing for the In the replacement String, a dollar sign ( $) followed by a number will be Implicitly for strings: val date = raw "(\d") The canonical way to create a Regex is by using the method r, provided Once, outside of loops and perhaps in a companion object. Since compilation is expensive, frequently used Regexes should be constructed The regular expression syntax for pattern strings.Īn instance of Regex represents a compiled regular expression pattern. See the documentation for for details about This class delegates to the package of the Java Platform. Definition Classes rootĪ regular expression is used to determine whether a string matches a patternĪnd, if it does, to extract or transform the parts that match. For example, on the JVM, String is an alias for. Other aliases refer to classes provided by the underlying platform. Some of these identifiers are type aliases provided as shortcuts to commonly used classes. Identifiers in the scala package and the scala.Predef object are always in scope by default. scala.swing - A convenient wrapper around Java's GUI framework called Swing (scala-swing.jar).- Parser combinators (scala-parser-combinators.jar).- Parallel collections (scala-parallel-collections.jar).scala.xml - XML parsing, manipulation, and serialization (scala-xml.jar).scala.reflect - Scala's reflection API (scala-reflect.jar).See the complete list on the right.Īdditional parts of the standard library are shipped as separate libraries. scala.sys - Interaction with other processes and the operating system.scala.math - Basic math functions and additional numeric types like.ncurrent - Primitives for concurrent programming such as.- Mutable, concurrent data-structures such as.- Mutable, sequential data-structures such as.
