status of runtime-class.lisp?

Reply Threaded

I was interested in using this facility, but it doesn't seem to work.
Does anyone know that it still should?
AFAIK it needs the asm 1.5.3 jars. Here's the invocation I did:

java -cp ./abcl.jar:asm-1.5.3.jar:asm-analysis-1.5.3.jar:asm-attrs-1.5.3.jar:asm-tree-1.5.3.jar:asm-util-1.5.3.jar:asm-xml-1.5.3.jar:kasm-1.5.3.jar
org.armedbear.lisp.Main

(java:jnew-runtime-class "TestClass" "java.lang.Object" nil '((nil
(lambda(&rest ignore)))) `(("test" "int" nil ,#'(lambda (&rest ignore)
1 )))

I get "evalutation aborted" or "too many nested errors" when I try this.

I have a patch ready that gets things working with asm3.1

I would be happy to do the final bits of work to get the patch applied, assuming the maintainers are ok with it.

Let me know if you're interested.

Definitely, I think it's a nice bit of functionality. I am certainly
looking forward to having&using it.

Hi Alan,

I don't know which revision ABCL you used and whether the
jnew-runtime-class "thing" uses our compiler, but loading the COMPILE
function was broken for about 2 or 3 days last week. I understand the
autoloader better now and I fixed it again.

Maybe that explains part of your issues?

Bye,

Erik.

There is an issue in that if one tries to create a runtime class that is not in a package, it causes an error. I don't know why, nor does Russel, so until we do I suggest we add the following at the entry to jnew-runtime-class

(assert (find #\. class-name :test 'char=) (class-name)

"Runtime classes need to be in some package and '~a' isn't" class-name)

OK, here's the patch. The simplest test case that I have works, but some of the more
complicated test cases that I have for this code are not presently working because of
recent abcl changes.

You need asm3.1 in class path for this.

I have another patch somewhere, not included here, that allows you to redefine
java classes on the fly. This is necessary if you really want to work in a lispy
style, changing things at will. I'll try to dig this up and submit it as well.

You have to manually load src/org/armedbear/lisp/runtime-class.lisp.

Here is the simplest case:

(jnew-runtime-class
"FOO.Bar3" "java.lang.Object"
nil ;;interfaces
nil ;;constructors
`(("a_method" ;;name
"int" ;;return type
("int" "int") ;;argument types
(lambda (x y &optional this)
(+ x y)) ;;the method itself
"public"))
;;methods
nil ;;fields
"/tmp/Bar.class" ;; this is optional
)

(let ((bar (jnew (jconstructor "FOO.Bar3"))))
(jcall (jmethod "FOO.Bar3" "a_method" "int" "int") bar 1 2))
