Hi,

Thanks for the quick replies. There's a mistake in the constructor in line 10. Must be $proto and not $package.

The code I posted is not the code of my complex program. It is an equivalent piece that is in a symanticly point of view the same. I now tested it and it did not work. I changed flattening into references and it presented the same results to me: I changed the first line of config.cfg to option1=HASBEENCHANGED while sleep(15).

FILE 'test.pl':
use strict; use Foo; my $object = Foo->new('admin'); $object->show_config(); sleep(15); $object->change_config(); $object->show_config();
FILE 'Foo.pm':
package Foo; use strict; my $config = _parse_file(); sub new { my $proto = shift(); my $status = shift() || 'normal'; my $package = ref($proto) || $proto; my $self = { status => $status }; bless($self, $package); return $self; } sub change_config { my $self = shift(); return unless $self->{status} ne 'admin'; $config = _parse_file(); } sub show_config { foreach (keys(%{$config})) { print "KEY: $_\tVALUE: $$config{$_}\n"; } } sub _parse_file { my $filename = 'test.cfg'; my %temp; open(CONFIG, "<$filename") or die "can not open!\n"; while (<CONFIG>) { chomp($_); my ($key, $value) = $_ =~ m/^(\w+)=(.*)$/; $value ||= ''; $temp{$key} = $value if ($key); } close(CONFIG); return \%temp; } 1;
FILE 'config.cfg':
option1=value1
option2=value2
option3=value3
Output:
KEY: option1    VALUE: value1
KEY: option2    VALUE: value2
KEY: option3    VALUE: value3
KEY: option1    VALUE: value1
KEY: option2    VALUE: value2
KEY: option3    VALUE: value3

reading between the lines is my real pleasure

Title:
Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
