NAME

Config::Utils - Common config utilities.

SYNOPSIS

 use Config::Utils qw(conflict hash hash_array);

 conflict($self, $config_hr, $key);
 hash($self, $key_ar, $val);
 hash_array($self, $key_ar, $val);

SUBOUTINES

conflict

 conflict($self, $config_hr, $key);

Check conflicts. Affected variables from $self:

 - set_conflicts - Flag, then control conflicts.
 - stack - Reference to array with actual 'C<$key>' key position.

Returns undef or fatal error.

hash

 hash($self, $key_ar, $val);

Create record to hash. Affected variables from $self:

 - config - Actual configuration in hash reference.
 - set_conflicts - Flag, then control conflicts.
 - stack - Reference to array with actual 'C<$key>' key position.

Returns undef or fatal error.

hash_array

 hash_array($self, $key_ar, $val);

Create record to hash.

If exists more value record for one key, then create array of values.

Affected variables from $self:

 - config - Actual configuration in hash reference.
 - set_conflicts - Flag, then control conflicts.
 - stack - Reference to array with actual 'C<$key>' key position.

Returns undef or fatal error.

ERRORS

 conflict():
         Conflict in '%s'.

 hash():
         Conflict in '%s'.

 hash_array():
         Conflict in '%s'.

EXAMPLE1

 use strict;
 use warnings;

 use Config::Utils qw(conflict);

 # Object.
 my $self = {
         'set_conflicts' => 1,
         'stack' => [],
 };

 # Conflict.
 conflict($self, {'key' => 'value'}, 'key');

 # Output:
 # ERROR: Conflict in 'key'.

EXAMPLE2

 use strict;

 # Object.
 my $self = {
         'config' => {},

         'stack' => [],
 };

 # Add records.
 hash($self, ['foo', 'baz1'], 'bar');
 hash($self, ['foo', 'baz2'], 'bar');

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

 # Output:
 # 0  HASH(0x955f3c8)
 #    'config' => HASH(0x955f418)

 #    'stack' => ARRAY(0x8edf6e0)
