Hi all -
not an important question here, more a discussion. I was wondering
which method is the more appropriate (nice and/or efficient) to
enumerate all the elements of a collection and the index of each
elements...
(a) ---- à la C
(1 to: collection size) do: [:index |
html render: 'Victime ', index printString.
html render:
collection at: index]
(b) --- indexOf
collection do: [:victim |
html render: 'Victime ', (collection indexOf: victim) printString.
html render: victim]
(c) ---- keysAndValuesDo:
collection keysAndValuesDo: [:index :victim |
html render: index printString.
html render: member]
(d) ---- using a local var
| index |
index := 0.
collection do: [:victim | index := index + 1.
html render: 'Victime ', index printString.
html render: victim]
What solution would you suggest ?
I think we forget (a) and (d)
I like (c) but maybe (b) is more readable ?
Maybe there is another way ?
Thanks
Cédrick
