NAME

Conf::Libconfig - Perl extension for libconfig

SYNOPSIS

  use Conf::Libconfig;
  my $self = new Conf::Libconfig;
  $self->read_file($cfg);
  $self->read_string("test:{key = \"only for test!\";};");
  my $value = $self->lookup_value("abc.edf");
  print $value;

  use Data::Dumper;
  my $arrayref = $self->fetch_array("cdef.abcd.arrayref");
  print Dumper $arrayref;
  my $hashref = $self->fetch_hashref("cdef.abcd.hashref");
  print Dumper $hashref;

  $self->add("fghj.rtyu", "binarykey", "0b1");
  $self->add_boolscalar("fghj.rtyu", "binarykey", 0);

  # if program is over, DESTROY can auto exit, and you can ignore function delete. 
  $self->delete();
