trace - Scala Dynamic Tracing -


i'm solving problem scala tracing. want environment after executing each line of scala file, means, program in scala, know line executing , variables existing now, every line. i'm using method of stepping. let program step or step return automatically(by editting scala ide in eclipse) every line, , want. long program, it's slow , cost large amount of memory, more 20gb! have better idea how achieve it?give me whole trace in source code format every line of program, source file path, line number , current variables. thanks!

afaik there no free/opensource tools task described, commercial ones:

they both can record runtime traces of jvm code , later can drill these understand has happened there.
