Re: java disassembler/assembler

Hello again,

Thank you all for your comments, they have given me a certain number of 
ideas.
Here is what I have already implemented in Jasmin :

- use of offsets or labels for branch targets, local variable visibility, 
exception handlers...

- you can arbitrarily set the following flags : ACC_ENUM, ACC_ANNOTATION, 
ACC_BRIDGE or ACC_VARARGS

- you can now specify the bytecode version. Example :
.bytecode 49.0

- you can now add a SourceDebugExtension attribute to the class with the 
following directive :
.debug "all your base"

- same thing for the EnclosingMethod attribute :
.enclosing method "some/package/Foo/someMethod(I)V"
or
.enclosing method "some/package/Foo"



Here is what I am going to implement :
- signatures
- StackMap attributes
- generic attributes, so that you can add your own even if it's not 
supported by Jasmin


Here is what I do NOT plan to implement for the moment :
- annotations. Unless someone finds a nice and smart syntax ;)
- constant pool edition. I know it would be great but it's just too much 
work for the moment. However, I think it would be possible to explicitly add 
some items to the constant pool (but not too sure it's really useful...)
- inner classes. Unless somebody needs it badly.


Each time I implement something in Jasmin, I also implement it in my 
disassembler, so it's quite comfortable to edit classes now. Any other idea 
?

About the classpath tools, why not. My code is already GPLd and the 
copyright agreement is not a problem I think. I have contacted them but 
didn't get any answer for the moment. I'm more afraid about rewriting huge 
parts of my program...

Regards,
Daniel
