hello monks!
i have a problem parsing a hash into a sub
new_packages($fcount,%new_db); sub new_packages { my %packages = $_[1]; print "Found $_[0] packages for download: $_\n" if ($fcount > 1); print "Found $_[0] package for download: $_\n" if ($fcount == 1); print "Which one would you like to install?:\n"; foreach my $key (keys (%packages)) { print "$key) $packages{$key} \n" } }
i get the following error:
Odd number of elements in hash assignment at ./slackup.pl line 49. Use of uninitialized value in concatenation (.) or string at ./slackup +.pl line 50. Found 3 packages for download: Which one would you like to install?: Use of uninitialized value in concatenation (.) or string at ./slackup +.pl line 54. 1)
the hash has these values:
%new_db = (1 => 'gedit-2.2.2-i386-1.tgz', 2 => 'ppp-3.4.1-i386-2.tgz')
where is my mistake i cant figure out!?

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.
