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

I use something like this:

package OpenOrDie; use strict; use warnings; use vars '@ISA @EXPORT $VERSION'; require Exporter; $VERSION = '0.30'; @ISA = 'Exporter'; @EXPORT = 'Open'; sub Open { my ($mode, $file) = @_; open my $fh, $mode, $file or die("Unable to open file '$file' using mode '$mode': $!") return $fh; }

Which I then use like:

use OpenOrDie; my $FILE = Open('<',$filename);

This also means I can catch the error consistently:

eval { my $FILE = Open('<',$filename); }; if ($@) { warn("Cannot parse configuration; $@"); $config{skip} = 1; }

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.
