NAME

Config::Dot::Array - Module for simple configure file parsing with arrays.

SYNOPSIS

my $cnf = Config::Dot::Array->new(%params);

my $struct_hr = $cnf->parse($string_or_array_ref);
$cnf->reset;
my $serialized = $cnf->serialize;

METHODS

new

Constructor.

  • callback

    Callback code for adding parameter. Callback arguments are:

    $key_ar - Reference to array with keys.
    $value - Key value.

    Default is undef.

  • config

    Reference to hash structure with default config data. This is hash of hashes or arrays structure.

    Default value is reference to blank hash.

  • set_conflicts

    Set conflicts detection as error.

    Default value is 1.

parse

my $struct_hr = $cnf->parse($string_or_array_ref);

Parse string $string_or_array_ref or reference to array $string_or_array_ref and returns structure.

Returns reference to hash.

reset

$cnf->reset;

Reset content in class (config parameter).

Returns undef.

serialize

my $serialized = $cnf->serialize;

Serialize 'config' parameter hash to output.

Returns string.

PARAMETER_FILE

# Comment.
# blabla

# White space.
/^\s*$/

# Parameters.
# Key must be '[-\w\.:,]+'.
# Separator is '='.
key=val
key2.subkey.subkey=val

# Arrays.
key3=val1
key3=val2

ERRORS

new():
        Bad 'config' parameter.
        Parameter 'callback' isn't code reference.
        From Class::Utils::set_params():
                Unknown parameter '%s'.

parse():
        Bad key '%s' in string '%s' at line '%s'.
        From Config::Utils::hash_array():
                Conflict in '%s'.

EXAMPLE1

use strict;
use warnings;

use Config::Dot::Array;
use Dumpvalue;

# Object.
my $struct_hr = Config::Dot::Array->new->parse(<<'END');
key1=value1
key2=value2
key2=value3
key3.subkey1=value4
key3.subkey1=value5
END

# Dump
my $dump = Dumpvalue->new;
$dump->dumpValues($struct_hr);

# Output:
# 0  HASH(0x9970430)
#    'key1' => 'value1'
#    'key2' => ARRAY(0x9970660)
#       0  'value2'
#       1  'value3'
#    'key3' => HASH(0x9970240)
#       'subkey1' => ARRAY(0xa053658)
#          0  'value4'
#          1  'value5'

EXAMPLE2

use strict;
use warnings;

use Config::Dot::Array;

# Object with data.
my $c = Config::Dot::Array->new(
        'config' => {
                'key1' => {
                        'subkey1' => 'value1',
                },
                'key2' => [
                        'value2',
                        'value3',
                ],
        },
);

# Serialize.
print $c->serialize."\n";

# Output:
# key1=subkey1.value1
# key2=value2
# key2=value3

EXAMPLE3

use strict;
use warnings;

use Config::Dot::Array;
use Dumpvalue;

# Object.
my $struct_hr = Config::Dot::Array->new(
        'callback' => sub {
               my ($key_ar, $value) = @_;
               if ($key_ar->[0] eq 'key3' && $key_ar->[1] eq 'subkey1'
                       && $value eq 'value3') {

                       return 'FOOBAR';
               }
               return $value;
        },
)->parse(<<'END');
key1=value1
key2=value2
key3.subkey1=value3
key3.subkey1=value4
END

# Dump
my $dump = Dumpvalue->new;
$dump->dumpValues($struct_hr);

# Output:
# 0  HASH(0x87d05e8)
#    'key1' => 'value1'
#    'key2' => 'value2'
#    'key3' => HASH(0x87e3840)
#       'subkey1' => ARRAY(0x87e6f68)
#          0  'FOOBAR'
#          1  'value4'
