Scala-Virtualized is an experimental branch of the Scala compiler and standard library that contains a few additions to provide even better support for embedded DSLs (we call that language virtualization).
The key features are as follows:
- overloadable while-loops, if-then-else statements, object construction, etc. (not only for-comprehensions)
- extension methods: define new infix-methods on existing types (pimp-my-library with less boilerplate)
Further descriptions and examples are available on the Scala-Virtualized Wiki.
An accompanying technial paper has even more in-depth information: pdf preprint, published version.
Tutorial source code is available at github.com/adriaanm/scala-virtualized-tutorial.
Here is a sample build.sbt file for use with the Simple Build Tool (SBT):
name := "My Scala-Virtualized Project"
version := "1.0"
scalaVersion := "2.11.2"
scalaOrganization := "org.scala-lang.virtualized"
Releases of Scala-Virtualized are binary compatible with the corresponding regular Scala release.
