Re: [Pharo-users] [Oharo-users] Copy AST

Hi everyone,

I want to get a deep copy of ast. But deepCopy doesn't work:) What I mean:

| ast1 ast2 | ast1 := RBParser parseRewriteExpression: 'self'. ast2 := ast1 copy."or without copy" ast1 stop: 99. ast2 stop

When evaluate this you get 99. I want it to be 4. So I want to have separate object ast2 with separate data, not depending on changes made in ast1. As I said deepCopy doesn't work. Any ideas?

I'd say beware. Deep copying ASTs is hard. You'll need to characterize a bit better what has been copied with deepCopy and what hasn't before starting to hack it. Thierry

Thanks, Mark
