Sorting case insensitively

[John Deuf]

Is there a way to sort case insensitively an array (without creating
another array with lowercase values for instance) ?

sort { uc($a) cmp uc($b) } @arr;

 

[Uri Guttman]

AK> sort { uc($a) cmp uc($b) } @arr;
BE> my @sorted = sort { lc $a cmp lc $b } @unsorted;

now make up your minds!! which one of those is better? will there be
another war on uc vs lc?

I thought there was a Right Answer to this: lc, as Unicode defines
mappings upper -> lower and title -> lower...?

@sorted = sort { uc($a) cmp uc($b) } @data;

# Note that you could also use "lc" instead of "uc" in
# the sorting specification
