[Soot-list] Pretty print

[Eric Bodden]

Hi Christiane.

Depending on what you are trying to do, this may be hard to
impossible. abc works by (1) transforming Java classes into Jimple and
AspectJ aspects into something called an AspectInfo. Then, abc (2)
weaves the Jimple code according to the AspectInfo and (3) produces
bytecode from the woven Jimple.

Therefore you can only print out Java or AspectJ code before step (2),
i.e. before the weaving because no Java/AspectJ representation of the
woven program exists. If you want to print the un-woven Java/AspecTJ
code, I can tell you how to do that, but I fear that you are trying to
accomplish something else.

If you want to convert the woven Jimple code back to Java you can try
to do so using the command line options "+soot -f dava -soot" to abc.
This is known to be buggy, though, and it will only produce plain Java
code. In other words, the generated code contains no pieces of advice
or pointcuts etc. but only appropriate advice methods.
