scala-parser-combinators

Scala Standard Parser Combinator Library

This library is now community-maintained. If you are interested in helping please contact @gourlaysama or mention it on Gitter.

As of Scala 2.11, this library is a separate jar that can be omitted from Scala projects that do not use Parser Combinators.

Documentation

• Current API
• A (perhaps somewhat outdated) Getting Started
• A more complicated example, Building a lexer and parser with Scala's Parser Combinators
• "Combinator Parsing", chapter 33 of Programming in Scala, Third Edition, shows how to use this library to parse arithmetic expressions and JSON. The second half of the chapter examines how the library is implemented.

Adding an SBT dependency

To depend on scala-parser-combinators in SBT, add something like this to your build.sbt:

libraryDependencies += "org.scala-lang.modules" %% "scala-parser-combinators" % "1.0.5"

(Assuming you're using a scalaVersion for which a scala-parser-combinators is published. The first 2.11 milestone for which this is true is 2.11.0-M4.)

To support multiple Scala versions, see the example in https://github.com/scala/scala-module-dependency-sample.

ScalaJS support

Scala-parser-combinators directly supports scala-js 0.6+, starting with v1.0.5:

libraryDependencies += "org.scala-lang.modules" %%% "scala-parser-combinators" % "1.0.5"
