How can I build AST from Scala code?

Question

How can I turn scala program into AST and operate with it programatically, from java/scala?

Take a look at scala reflection API -- it allows you to manipulate with scala as AST (trees section in particular) — om-nom-nom

Is the program already compiled? In the source code, you can inject a macro to get hold of the corresponding AST of some expression. — 0__

It's source code. I know little about the macro. Could you please show me some examples? Thanks! — Fei Luo
