( #3333=superdoc: print w/replies, xml ) Need Help??

I changed this around to do it for arbitrary coderefs, since I get to deal with some that come from other sources. Instead of catching them at definition time, I "enchant" them later.

This looks like it could be a useful decorator if I work on the concept a little more. So Randal, who wants to upload it to CPAN first?

#!/usr/bin/perl my $a = sub { print "I am A\n" }; my $b = sub { print "I am B\n" }; $a->(); $b->(); $c = MagicalCodeRef->enchant( $a ); $a->(); print STDERR "That was $a I just called\n"; BEGIN { package MagicalCodeRef; use overload '""' => sub { require B; my $ref = shift; my $gv = B::svref_2object($ref)->GV; sprintf "%s:%d", $gv->FILE, $gv->LINE; }; sub enchant { bless $_[1], $_[0] } }

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.
