Heredocs allow you to use a single blank line as your end delimeter if you wish. This means that rather than writing

print <<"Done"; foo bar baz Done print "aha!\n";

, you can write

print <<""; foo bar baz print "aha!\n";

(note the lack of anything but a blank line between "baz" and the following print statement). It was previously allowed to use

print <<; foo bar baz print "aha!\n";

(note the plain and simple "print <<;" line). You can still use that simple version, but it's best not to as there is no guarantee that such functionality will be reserved in future perl versions (and that is why the warnings pragma will cough up that deprecated message if you use "print <<;").

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.
