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

In my experience, conditionally loading a module (like Corion and tobyink already showed) isn't always the only thing going on, since later on in your code you might want to use functions from that module conditionally, based on whether it was loaded in the first place. Personally, I prefer to set a global variable, something like this:

our $HAVE_XYZ; BEGIN { $HAVE_XYZ = !!$ENV{USE_XYZ} } use if $HAVE_XYZ, 'XYZ'; ... if ( $HAVE_XYZ ) { XYZ::foo(...) }

Also, note that BEGIN is uppercase, not begin {...}.

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

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 or How to display code and escape characters are good places to start.
