NAME

Bio::Gonzales::Util - Utility functions for common tasks

SYNOPSIS

            

              
              
use Bio::Gonzales::Util qw(undef_slice slice invslice flatten hash_merge as_arrayref);
            
          

SUBROUTINES

%sliced_hash = slice(\%hash, @keys_to_slice)

$sliced_hash = slice(\%hash, \@keys_to_slice)

return a new hash with all keys removed that are not in @keys_to_slice.

$sliced_hash = undef_slice(\%hash, \@keys_to_slice)

%sliced_hash = undef_slice(\%hash, @keys_to_slice)

same as slice, but if a key in @keys_to_slice does not exist in %hash, it will result in a additional entry with its value undefined

            

              
              
my %hash = (
  a => 1,
  b => 2,
  c => 3
);
my %sliced_hash = undef_slice(\%hash, qw/a b d/);
# will result in
%sliced_hash = (
  a => 1,
  b => 2,
  d => undef
);
            
          

%sliced_hash = invslice(\%hash, @keys_to_exclude)

\%sliced_hash = invslice(\%hash, \@keys_to_exclude)

@elements = flatten($nested_array1, $nested_array2)
