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

Much fun was spent today tracking down a mysterious bug. I even had fun shoving a coderef into @INC to find out what was loading the errant module. I've now reproduced a minimal test case. Once I put it together, the bug was clear, but before that, there were many red herrings. Here's a minimal test case.

package Package1; use base 'Exporter'; our @EXPORT_OK = qw/this that/; our %EXPORT_TAGS = ( all => [qw/this that/], ); sub this { 'this' } sub that { 'that' } 1;

And another package:

package Package2; use base 'Exporter'; use Package1 ':all'; our @EXPORT_OK = ( @Package1::EXPORT_OK, 'foobar' ); our %EXPORT_TAGS = %Package1::EXPORT_TAGS; push @{ $EXPORT_TAGS{all} } => 'foobar'; sub foobar { 'foobar' } 1;

Do you see the bug? That was very, very annoying, but fortunately the fix is easy. If you see the bug, post it as a spoiler.

Cheers,

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