Hi List,
I have a hashmap/array construct where i want to lookup data. my current
lookup looks like that:
foo_uses_a => [ $foo[''bar''][''a''],
$foo[''bar2''][''a''] ],
foo_refers_b => [ $foo[''bar''][''b''],
$foo[''bar2''][''b''] ];
Is There a way to skip to double reference of $foo and [''a'']
or [''b''] per
line? And make everything a bit nicer?
It is possible to change the construct to a complete hashmap if that helps.
$foo = {
''bar'' => {
''a'' => [
''1'',
''2'',
''3
''4'',
],
''b'' => [
''1'',
''2'',
''3'',
''4'',
''5'',
''6'',
],
},
''bar2'' => {
''a'' => [
''1'',
''2'',
''3
''4'',
],
''b'' => [
''1'',
''2'',
''3'',
''4'',
''5'',
''6'',
],
},
}
Thanks for help
Simon

You could do something like this, though: $foobar = $foo[''bar''] $foobar2 = $foo[''bar2''] [...] foo_uses_a => [$foobar[''a''], $foobar2[''a'']], foo_refers_b => [$foobar[''b''], $foobar2[''b'']]; I don''t see much difference there, myself. Ultimately, there is no way around the fact that if you use a nested data structure then you need multiple indices to select data from deep inside. The only real solution is to structure your data so that you don''t need to select as deeply, but that''s not always feasible.
