Glad you got it working, Stefano! The SqueakJS VM currently has an artificial limit of 100 MB. This is not an actual limit, but just there to prevent bugs from filling up all the memory. There is a line "this.totalMemory = 100000000;" in the JS file somewhere. You could try appending another 0 to that and see if it works. - Bert - On Tue, Feb 11, 2020 at 1:20 AM stefano federici <s_federici(a)yahoo.com> wrote: > I just noticed that, whereas Scratch manages quite well projects whose > size is more than 250MBs, it seems that ScratchJS cannot load projects > bigger than 20MBs.

recompile:[from:]
by Eliot Miranda 11 Feb '20

11 Feb '20

Hi All, I find myself using something like this to copy methods across hierarchies: [:s| | class | self halt. class := CogVMSimulator whichClassIncludesSelector: s. StackInterpreterSimulator recompile: s from: class. StackInterpreterSimulator organization classify: s under: (class whichCategoryIncludesSelector: s)] value: #printStringOf:on:. because if one simply does recompile:from: and the selector doesn't exist in the target then one ends up with a hidden selector; it's in the method dictionary but because it isn't in the organization it doesn't show in the browser or in Monticello etc. The rationale for not having recompile:from: check the organization is a good one; when recompiling a class that has changed shape (had inst vars added or removed) we don't want to waste cycles checking something redundant. So how about having ClassDescription>>recompile:from: doing the check if the receiver doesn't equal the argument class, e.g.: ClassDescription>>recompile: selector from: oldClass "Preserve the originalTraitMethod (if any) after recompiling a selector" | oldMethod | oldMethod := oldClass compiledMethodAt: selector. super recompile: selector from: oldClass. oldMethod originalTraitMethod ifNotNil: [:traitMethod| (self compiledMethodAt: selector) originalTraitMethod: traitMethod]. (self ~~ oldClass and: [(organization numberOfCategoryOfElement: selector) = 0]) ifTrue: [organization classify: selector under: (oldClass whichCategoryIncludesSelector: oldClass)] _,,,^..^,,,_ best, Eliot
