Full Discussion: sprintf result on perl
Top Forums Shell Programming and Scripting sprintf result on perl Post 302295970 by pludi on Tuesday 10th of March 2009 05:01:05 AM

Usually, you assign the result of sprintf to a scalar ($) instead of an array (@). With an array as left side operator, you get the result of sprintf in the first and only element of the array.

What's the code in question that works incorrectly?

HTML::Microformats::Datatype::String(3pm)		User Contributed Perl Documentation		 HTML::Microformats::Datatype::String(3pm)

NAME

       HTML::Microformats::Datatype::String - text in a particular language

SYNOPSIS

	my $string = HTML::Microformats::Datatype::String
		       ->new('Bonjour', 'fr');
	print "$string
";

DESCRIPTION

   Constructor
       "$str = HTML::Microformats::Datatype::String->new($text, [$lang])"
	   Creates a new HTML::Microformats::Datatype::String object.

   Public Methods
       "$str->lang"
	   Return the language code.

       "$str->to_string"
	   Return a plain (scalar) string.

   Functions
       "$str = ms($text, [$element])"
	   Construct a new HTML::Microformats::Datatype::String object from a scalar, plus XML::LibXML::Element. If $element is undef, then
	   returns the plain (scalar) string itself.

	   This function is exported by default.

	   (Note: the name 'ms' originally stood for 'Magic String'.)

       "isms($str)"
	   Returns true iff $str is blessed as a HTML::Microformats::Datatype::String object.

	   This function is exported by default.

       "$c = concat($a, $b, [$reverse])"
	   Concatenates two strings.

	   If the language of string $b is null or the same as $a, then the resultant string has the same language as $a. Otherwise the result has
	   no language.

	   If $reverse is true, then the strings are concatenated with $b preceding $a.

	   This function is not exported by default.

	   Can also be used as a method:

	    $c = $a->concat($b);

       "compare($a, $b)"
	   Compares two strings alphabetically. Language is ignored.

	   Return values are as per 'cmp' (see perlfunc).

	   This function is not exported by default.

	   Can also be used as a method:

	    $a->compare($b);
