[Pharo-users] Re: How can I make this more OOP

In a language like Java or C# or Ada we can insist at compile time that an argument conforms to a protocol, whatever class it might be an instance of. In Smalltalk, we can use #isKindOf: to test whether an object inherits from a class, but that is often the wrong test. We can use (multiple calls

And the cool thing about it is that we will have soon a mailing list for github and other logs (that we can browse while not be forced to register too) and with that Pharo-dev will be less polluted and we want to have it back a place to exchange about Pharo. S.

+100^100. As Susan Leigh Star said, infrastructure is invisible until it fails. So all the work behind the invisible to keep it running, lean and smooth is really important. Offray On 15/09/20 3:06 a. m., Sven Van Caekenberghe wrote: > >> On 14 Sep 2020, at 17:46, Sean P. DeNigris wrote: >> >>

Oke, I can try this but im afraid the test which test a particular error il fail. The error messages are given. And I miss you.  yes, SequenceableCollection has with do: but should I add the with count to it ? Roelof

SequenceableCollection has with:do:. Add with: other count: testBlock |r| r := 0. self with: other do: [:x :y | (testBlock value: x value: y) ifTrue: [r := r + 1]]. ^r I have this in my library anyway. Now distanceStrand1: a strand2: b ^a with:

[Pharo-users] Re: Rounding in Floats

If you are going to use floating point numbers in any programming language, Pharo included, you need to understand something about them. Things like - the relevant precision is *fixed*; a Float in Pharo is *always* a 64-bit IEEE floating-point number, which amongst other things means (to a

[Pharo-users] Re: How can I make this more OOP

I take Sean's point. However, while I agree that practising using polymorphism instead of 'if' is a good idea, I don't think that *this* exercise is a good one for getting such practice. Roelof is going through the Pharo track of Exercism. This particular one is called 'flatten-array'. The one con
