In Reflectivity, we have an AST for every method. In addition, the AST can be annotated with non-source visible annotations. So what I want to explore is to have a very compact representations of ASTs, but one that does not lose information *and* that allows the AST to be annotated with non-textual objects even when it's compressed.

Re: [Pharo-project] is it possible to know the memory occupation (bytes) of an object?

by Adrian Lienhard

Its a simple method in Object: Object>>sizeInMemory "Returns the number of bytes used by this object in memory (including its header)" | headerSize instanceSize | headerSize := (self class indexIfCompact > 0 ifTrue: [ 4 ] ifFalse: [ 8 ]). instanceSize := (self class isVariable ifFalse: [ self class instSize * Smalltalk wordSize ] ifTrue: [ (self basicSize * (self class isBytes ifTrue: [ 1 ] ifFalse: [ Smalltalk wordSize ])) ]). ^ headerSize + instanceSize Please also note the other mail I sent to this thread.

BTW, Lukas had pointed out that my implementation is incomplete. So before integrating we should make sure the implementation covers all cases.

I once sent some code to the mailing list (search for thread named "Size of objects"). We should add this to the image. I think I named it #sizeInMemory.

It's open source and based on Seaside, so not to difficult to have something similar for pharo hosted at : http://doc.pharo-project.org/ On Tue, Apr 27, 2010 at 4:03 PM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > http://philemonworks.wordpress.com/2009/11/13/soek-goodies-st-exploring-ope… > > > Stef > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > -- Serge Stinckwich UMI UMMISCO 209 (IRD/UPMC), Hanoi, Vietnam Every DSL ends up being Smalltalk http://doesnotunderstand.org/
