[scala-tools] eclipse plugin -Xprint and java disassembly

[Naftoli Gugenheim]

Sure, double-click on the class file in the output folder from the Navigator view.
In general, it would be nice if eclipse could tell me the scala command line it generates so I could paste it in a command line and modify it, e.g. for the OP's use case, or to get around the fact that I don't seem to have enough memory to run the interpreter inside eclipse, etc.

Not at the moment, no.

Sure. It might be a nice feature in the future.

Doesn't Eclipse's built in classfile viewer do this job for you?
Failing that, I'm pretty sure there are several very capable bytecode
disassembler plugins around.

That's great, thanks! I'm pretty new to Eclipse, sorry.

Yeah, I figured that out :) Thanks.

Try modifying eclipse.ini's -Xmx1024m (or, maybe, -Xmx8192m, depending on how bad your jvm is).

I don't know, maybe someone can help me. I have 2Gb of RAM but the JVM doesn't let me start eclipse with -Xmx > ~650Mb.
