Ok, a little more headbanging and I seem to have gotten farther (maybe?).
At least the error message has changed. Now I'm getting:
BUG! exception in phase 'class generation' in source unit 'CtxTest2.groovy' Operation: (<assignment
operator>: "=" ) not supported
Searching hasn't helped with this one.
The xform-ed code looks good -- in fact, if I type the code into a separate
groovyConsole, it will run. (The console AST generation works up thru
the Instruction Selection phase, obviously.)
I'm guessing it's still with how I'm setting up the scoping (or how I'm not
setting up the scoping).

Maybe I'm too late, and that's why things aren't coming together ;)
Specifically, I haven't figured out how to inject a variable into the
scope of an outer
with's closure that can be used by code in an interior with's closure.
__outerCtx1 = null // injected statement
__currCtx1 = myCtx1 // injected statement
.... some code ...
__outerCtx2 = __currCtx1 // injected statement <--- doesn't
__currCtx2 = myCtx2 // injected statement
where is __currCtx1 and __outerCtx1 coming from? Are they supposed to be new local variables? in
that case you will have to add a DeclarationStatement, not just an assignment to a
VariableExpression. Otherwise the compiler will thnk they are dynamic properties and tries to
resolve them against the context.
as for the logic behind __outerCtxN... with number wouldn't have to be null I would have said you
should think of using getOwner on Closure
Hmmm, I'm close to that, but not quite the same. I was trying
ExpressionStatement currCtx = new ExpressionStatement(
new DeclarationExpression (
new VariableExpression( "__currCtx$levelcnt"),
new Token( Types.ASSIGNMENT_OPERATOR, "=", -1, -1),
new MethodCallExpression( new VariableExpression( 'this'), 'getDelegate', new
Would a DeclarationStatment act differently from an ExpressionStatement with an
DeclarationExpression? If my foggy memory is correct, I wrote my code after
looking at the
AST displayed for a short test script in groovyConsole.
Plus, if foggy memory serves, I tried using getOwner and it came back with the
owned by the test script, not the object doing the with. Calling getDelegate
gave me the object.
If foggy memory serves.
I also tried playing around with setClosureSharedVariable( true) and
without success. But, those were somewhat blind stabs in the dark, so I might
not have been
using them correctly.
Looking at the AST generated by groovyConsole, my transform looks like it is
the compiler complains about things not being in scope (in the inner closure).
So, I'm doing
something wrong with setting up the scoping.
