in reply to How to save and reload my hash

"... save and reload..."

A not thoroughly tested little sketch with JSON - the data structure is from the examples planetscape linked to:

#!/usr/bin/env perl use strict; use warnings; use Data::Dump; use Path::Tiny; use JSON::Tiny qw(decode_json encode_json); use feature qw(say); my $ref = { a => [ 1, 2, 3 ], b => [ { X => 1, Y => 2 }, { X => [ 1, 2, 3 ], Y => [ 4, 5, 6 ], Z => [ 7, 8, 9 ] }, ], }; say q(-) x 4; say ref $ref; say q(-) x 4; dd $ref; my $json = encode_json($ref); my $file = path(q(data.json)); $file->spew_utf8($json); say q(-) x 4; $ref = decode_json( $file->slurp_utf8 ); say ref $ref; say q(-) x 4; dd $ref; __END__ karls-mac-mini:playground karl$ ./510202.pl ---- HASH ---- { a => [1, 2, 3], b => [ { X => 1, Y => 2 }, { X => [1, 2, 3], Y => [4, 5, 6], Z => [7, 8, 9] }, ], } ---- HASH ---- { a => [1, 2, 3], b => [ { X => 1, Y => 2 }, { X => [1, 2, 3], Y => [4, 5, 6], Z => [7, 8, 9] }, ], }

Please see also JSON::Tiny and Path::Tiny.

Best regards, Karl
