Hi,
In Perl, is it possible to use a range of numbers with '..' as a key in a hash?
Something in like:
%hash = (
'768..1536' => '1G',
'1537..2560' => '2G'
);
That is, the range operation is evaluated, and all members of the range are... (3 Replies)

I have a script with dynamic hash of hashes , and I want to print the entire hash (with all other hashes).
Itried to do it recursively by checking if the current key is a hash and if yes call the current function again with refference to the sub hash.
Most of the printing seems to be OK but in... (1 Reply)

Hash::Merge::Simple(3pm) User Contributed Perl Documentation Hash::Merge::Simple(3pm)
NAME
Hash::Merge::Simple - Recursively merge two or more hashes, simply
VERSION
version 0.051
SYNOPSIS
use Hash::Merge::Simple qw/ merge /;
my $a = { a => 1 };
my $b = { a => 100, b => 2};
# Merge with righthand hash taking precedence
my $c = merge $a, $b;
# $c is { a => 100, b => 2 } ... Note: a => 100 has overridden => 1
# Also, merge will take care to recursively merge any subordinate hashes found
my $a = { a => 1, c => 3, d => { i => 2 }, r => {} };
my $b = { b => 2, a => 100, d => { l => 4 } };
my $c = merge $a, $b;
# $c is { a => 100, b => 2, c => 3, d => { i => 2, l => 4 }, r => {} }
# You can also merge more than two hashes at the same time
# The precedence increases from left to right (the rightmost has the most precedence)
my $everything = merge $this, $that, $mine, $yours, $kitchen_sink, ...;
DESCRIPTION
Hash::Merge::Simple will recursively merge two or more hashes and return the result as a new hash reference. The merge function will
descend and merge hashes that exist under the same node in both the left and right hash, but doesn't attempt to combine arrays, objects,
scalars, or anything else. The rightmost hash also takes precedence, replacing whatever was in the left hash if a conflict occurs.
This code was pretty much taken straight from Catalyst::Utils, and modified to handle more than 2 hashes at the same time.
USAGE
Hash::Merge::Simple->merge( <hash1>, <hash2>, <hash3>, ..., <hashN> )
Hash::Merge::Simple::merge( <hash1>, <hash2>, <hash3>, ..., <hashN> )
Merge <hash1> through <hashN>, with the nth-most (rightmost) hash taking precedence.
Returns a new hash reference representing the merge.
NOTE: The code does not currently check for cycles, so infinite loops are possible:
my $a = {};
$a->{b} = $a;
merge $a, $a;
NOTE: If you want to avoid giving/receiving side effects with the merged result, use "clone_merge" or "dclone_merge" An example of this
problem (thanks Uri):
my $left = { a => { b => 2 } } ;
my $right = { c => 4 } ;
my $result = merge( $left, $right ) ;
$left->{a}{b} = 3 ;
$left->{a}{d} = 5 ;
# $result->{a}{b} == 3 !
# $result->{a}{d} == 5 !
Hash::Merge::Simple->clone_merge( <hash1>, <hash2>, <hash3>, ..., <hashN> )
Hash::Merge::Simple::clone_merge( <hash1>, <hash2>, <hash3>, ..., <hashN> )
Perform a merge, clone the merge, and return the result
This is useful in cases where you need to ensure that the result can be tweaked without fear of giving/receiving any side effects
This method will use Clone to do the cloning
Hash::Merge::Simple->dclone_merge( <hash1>, <hash2>, <hash3>, ..., <hashN> )
Hash::Merge::Simple::dclone_merge( <hash1>, <hash2>, <hash3>, ..., <hashN> )
Perform a merge, clone the merge, and return the result
This is useful in cases where you need to ensure that the result can be tweaked without fear of giving/receiving any side effects
This method will use Storable (dclone) to do the cloning
