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

but it doesn't work for me:

Not surprising, $/="\n" assignment is always true (and assignment ), 5.12 is not a module (maybe you wants features), and 5.12 doesn't export say (features you want, maybe)

Apparently, 'use if' can only see a global variable that exists at compile time.

nothing specific to if, that is the nature of compile-time and our/my, initialization doesn't happen until later

use constant DEBUG => !!( 0 || $ENV{PERL_DEBUG_MYAPPNAME} );
use if DEBUG , qw' Carp::Always ';

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.
