( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Trimming down, even before I have a small case that shows the error I have something else wrong. Here're two files that give me different results on 5.8.8 versus 5.10. I think I've already done something wrong at this level of simplicity that I should figure out before building the example up farther.

use strict; use warnings; use configthing qw(); our configthing $cfg = new configthing; use Data::Dumper; print Dumper $cfg;

Then for "configthing.pm"...

package configthing; use strict; use warnings; use fields qw( a b c d ); our %DEFAULTS = ( b => 'default for b', c => 'default for c' ); 1; sub new { my $this = shift; unless (ref $this) { $this = fields::new($this); } our %FIELDS; foreach my $k ( keys(%FIELDS) ) { $this->{$k} = '' unless defined($this->{$k}); } $this->{a} = 'set at initialization'; foreach my $k ( keys(%DEFAULTS) ) { $this->{$k} = $DEFAULTS{$k}; } return $this; }

With 5.8.8 I get

$VAR1 = bless( [ bless( { 'c' => 3, 'a' => 1, 'b' => 2, 'd' => 4 }, 'pseudohash' ), 'set at initialization', 'default for b', 'default for c', '' ], 'configthing' );

And 5.10.1 gives me:

$VAR1 = bless( { 'c' => 'default for c', 'a' => 'set at initialization', 'b' => 'default for b', 'd' => '' }, 'configthing' );

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.
