YAML::PP::Schema::Tie::IxHash - (Deprecated) Schema for serializing ordered hashes
use YAML::PP; use Tie::IxHash; my $yp = YAML::PP->new( schema => [qw/ + Tie::IxHash /] ); tie(my %ordered, 'Tie::IxHash'); %ordered = ( U => 2, B => 52, ); my $yaml = $yp->dump_string(\%ordered); # Output: --- U: 2 B: 52
This is deprecated. See the new option preserve in YAML::PP.
preserve
This schema allows you to dump ordered hashes which are tied to Tie::IxHash.
This code is pretty new and experimental.
It is not yet implemented for loading yet, so for now you have to tie the hashes yourself.
Examples:
# Code tie(my %order, 'Tie::IxHash'); %order = ( U => 2, B => 52, c => 64, 19 => 84, Disco => 2000, Year => 2525, days_on_earth => 20_000, ); \%order; # YAML --- U: 2 B: 52 c: 64 19: 84 Disco: 2000 Year: 2525 days_on_earth: 20000
# Code tie(my %order, 'Tie::IxHash'); %order = ( U => 2, B => 52, c => 64, 19 => 84, Disco => 2000, Year => 2525, days_on_earth => 20_000, ); bless \%order, 'Order'; # YAML --- !perl/hash:Order U: 2 B: 52 c: 64 19: 84 Disco: 2000 Year: 2525 days_on_earth: 20000
