Path >> printString returns a self-evaluating representation, which is fine. Its symmetric is thus Compiler >> evaluate: aString. (Path from: aString) parses the unix/url representation of a path and results in a Path instance. As far as I understand, #fullName should be the symmetric of that, so that we always have (modulo syntactic normalization, maybe) : (Path from: aString) fullName = aString Note that there's an edge case with the empty string that is wrong (at least it should be confusing to unix guys): Path from: ''. "Path root" Usually the absolute path for the root of the filesystem is explicitly noted '/', and an empty path is equivalent to '.' -- Damien Pollet type less, do more [ | ] http://people.untyped.org/damien.pollet
