But this *is* a discussion about the tools, not the implementation. ZnUrl is an example of class in the image that has a print representation like your object.
So it looks like this (doing Print It in a Playground) (for me): 'https://pharo.org' asUrl. "https://pharo.org/"; 'https://pharo.org' asUrl printString. "'https://pharo.org/'" But you seem to use a modification where the $" are not used ? I guess that the reason those $" are there is to make it a legal expression. Anyway, I do not see an underlying problem, only a possible discussion about what you would expect from the tools. Strings are poor representations, make them auto evaluate would make for much uglier text. I would not particularly like the following: 'https://pharo.org' asUrl. "ZnUrl fromString: 'https://pharo.org'" Or even: 'https://pharo.org' asUrl. "(ZnUrl fromString: 'https://pharo.org')" Though it is an option. (This goes for all similar objects, like date, time, ..). Then it does become a discussion about what a print string should be. > On 19 Feb 2017, at 11:42, stepharong <[email protected]> wrote: > > On Sun, 19 Feb 2017 11:40:04 +0100, Sven Van Caekenberghe <[email protected]> > wrote: > >> Ah, you're right: there is a difference between printing a textual >> representation on a stream / window and doing the same with the actual >> (print)string.
