Hi, how can I make the following code compile in Pharo 3.0? This is part of Grease ( https://ci.inria.fr/pharo-contribution/job/Grease/PHARO=30,VERSION=stable,VM... ): GRPharoPlatform>>compile: aString into: aClass classified: aSymbol "The trick here is to be as silently a possible so that the package is not marked dirty when running WAFileLibrary test. This also makes running tests much faster." | methodNode compiledMethod selector methodAndNode | methodNode := aClass compilerClass new compile: aString in: aClass notifying: nil ifFail: [ GRError signal: 'syntax error' ]. selector := methodNode selector. methodAndNode := CompiledMethodWithNode generateMethodFromNode: methodNode trailer: aClass defaultMethodTrailer. compiledMethod := methodAndNode method. compiledMethod putSource: aString fromParseNode: methodAndNode node inFile: 2 withPreamble: [ :file | aClass printCategoryChunk: aSymbol asString on: file priorMethod: (aClass compiledMethodAt: selector ifAbsent: [ nil ]). file cr ]. aClass addSelectorSilently: selector withMethod: compiledMethod. self doSilently: [ aClass organization classify: selector under: aSymbol ] -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."
