( #3333=superdoc: print w/replies, xml ) Need Help??
If I understand you right you're looking for something like...
@list = qw (one two three); %args = ( arg1 => 'string', arg2 => 5, arg3 => \@list ); sub1(%args); sub sub1 { my %args = ( arg1 => 'default', arg2 => 0, arg3 => undef, @_ ); print "$_ => $args{$_}\n" for keys %args; }
For me this prints out
arg1 => string arg2 => 5 arg3 => ARRAY(0x1a72f84)

This allows you to pass in the arguments as a hash, provide defaults in the subroutine, and override them with arguments passed in. This is right out of 'Effective Perl Programming' by Joeseph Hall and Randal Schwartz.

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.
