NAME

Config::Dot - Module for simple configure file parsing.

SYNOPSIS

use Config::Dot;

my $cnf = Config::Dot->new(%params);
my $struct_hr = $cnf->parse($string);
$cnf->reset;
my $serialized = $cnf->serialize;

METHODS

new

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

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 structure.

    Default value is reference to blank hash.

  • set_conflicts

    Set conflicts detection as error.

    Default value is 1.

Returns instance of object.

parse

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

Parse string $string_or_array_ref or reference to array $string_or_array_ref. Use $INPUT_RECORD_SEPARATOR variable to split lines.

Returns hash structure with configuration.

reset

$cnf->reset;

Reset content in class (config parameter).

Returns undef.

serialize

my $serialized = $cnf->serialize;

Serialize 'config' hash to output. Use $INPUT_RECORD_SEPARATOR variable to join lines.

Returns string with serialized configuration.

PARAMETER_FILE

# Comment.
# blabla

# White space.
/^\s*$/

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

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():
                 Conflict in '%s'.

serialize():
        Unsupported stay with newline in value.

EXAMPLE1

use strict;
use warnings;

use Config::Dot;
use Data::Printer;

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

# Dump.
p $struct_hr;

# Output:
# {
#     key1   "value1",
#     key2   "value2",
#     key3   {
#         subkey1   "value3"
#     }
# }

EXAMPLE2

use strict;
use warnings;

use Config::Dot;

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

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

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

EXAMPLE3

use strict;
use warnings;

use Config::Dot;
use Data::Printer;

# Object.
my $struct_hr = Config::Dot->new(
        'callback' => sub {
               my ($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
END

# Dump.
p $struct_hr;

# Output:
# {
#     key1   "value1",
#     key2   "value2",
#     key3   {
#         subkey1   "FOOBAR"
#     }
# }
