Code generation with Scala

Question

When using the SBT toolchain in Scala, is it possible to write a task that will read a special part of the project\'s source to generate scala-code at compile time.

Any

Answer 1

treehugger.scala is a library designed for code generation.

import treehugger.forest._
import definitions._
import treehuggerDSL._

val tree: Tree = Predef_println APPLY LIT("Hello, world!")

println(tree)
println(treeToString(tree))

The above code prints two lines:

Apply(Ident(println),List(Literal(Constant(Hello, world!))))
println("Hello, world!")

treehugger does generate an AST, but non-compliant to scalac's AST.
