initializeWith* and constructors

by Peter UhnÃ¡k

It seems to me that Smalltalkers are not very fond of constructors and I can't comprehend why. If for example I want to create object X that _needs_ object Y, then I would have to make a Y accessor. X>>y: anY y := anY but this makes no sense as I can still change the `y` object at later date breaking everything. An alternative is having: X>>initializeWithY: anY y := anY. self initialize. X>>y: anY ^ self basicNew initalizeWithY: anY. However I see only 59 initializeWith* methods (in about 6 packages) compared to 2302 initialize methods. Thus I am deducing that doing this is not very common. Am I missing something or am I trying to unnecessarily constraint the user and I should just trustâ¢ him that he knows what he should use? As a user of an interface I would prefer not to have useless things available that would just break things. Thanks, Peter

Re: [Pharo-users] Pharo 4 Playground open file menu

by Sergio Fedi

âFrom a usability and design point of view adding more elements to something does not necessarily improve it (i.e. the famous "less is more") The human attention is a limited resource and it has to be managed accordingly. The "About" option in the Playground (and in another tools) is a good place to put information about the tool it's purpose, how to use it, how it is related to other tools and external links. But it is an option that is not immediately obvious to access. So one thing I would do is give it more exposition, more readily access. Another typical feature in introducing new features to a user is to make it glow/shine/animate/pop up a message the first time it opens, introducing it's purpose and usage and allowing the user to bypass the message or let it keep coming back (later this information could be accessed via the About or Help option, as it is now)

playground cache is actually not nice when scripts are to be part of a project with a name etc. And I have a ton of files in it. I can't remember which is which. I have scripts to do lots of cli things and I like the save as of the workspace. But I have done extra key bindings for getting the ws or the playground.
