Hello

Maybe you could call it
#tupleDo:?
��������������� #(1 2 3)
tupleDo: [:a :b :c | �]

Subject: [Esug-list] destructDo:
Hi,
I am using a nice little
method #destructDo: for a while now and it feels good.
In VisualWorks:
SequenceableCollection>>destructDo:
aBlock
���������������
��������������� "Evaluate aBlock with the receiver's
elements as parameters.
���������������
��������������� aBlock takes its arguments from the
receiver.
���������������
��������������� 'ok'
���������������
��������������� #(1 2 3) destructDo: [:a :b :c | a + b + c]
���������������
��������������� #(1 2 3) destructDo: [:a :b | a + b]
���������������
��������������� #(1 2 3) destructDo: [:a | a]
���������������
��������������� #(1 2 3) destructDo: [42]
���������������
��������������� 'not ok'
���������������
��������������� #(1 2 3) destructDo: [:a :b :c :d | a + b +
c + d]
���������������
��������������� "
���������������
��������������� ^aBlock cullWithArguments: self asArray
In Amber:
SequenceableCollection>>destructDo:
aBlock
���������������
��������������� ^aBlock valueWithPossibleArguments: self
In Pharo and other
dialects, I don�t know, but should be as easy.
For example you can do
���������������
(('2020-03-28' tokensBasedOn: $-) collect: #asNumber)
destructDo: [:year :month :day |
������������������������������
Date newDay: day monthNumber: month year: year]
I like that the block is
not the receiver (like with #valueWithArguments or
#cullWithArguments), but the last argument.
Now the questions:
- I am sure that others came up with this.
Anybody knows?
- What are you using for this pattern?
- I don�t really like the name, but haven�t
found anything better yet. Maybe #destructedDo: or just
#destructed: or: #withPartsDo:� maybe something shorter?
Ideas?
- What are you thinking about this?
Happy hacking,
���������������
Christian
