Hi everyone,
About twice a week I start looking for a straightforward way to
turn a list of associations into a dictionary, spend a while searching,
and give up, ending up with a messy explicit loop.
Example:
| words lengths |
words := #('abc' 'defg').
lengths := Dictionary new.
words do:
[ :each | lengths at: each put: each size ].
lengths
Is there really no way to this with less code? I'd expect the following
to work:
| words lengths |
words := #('abc' 'defg').
lengths := Dictionary withAll:
(words collect: [ :each | each -> each size ]).
but it looks like Dictionary>>#withAll: was specifically designed to
make this impossible (because with the default implementation in
Collection it would work).
Konrad.
