Eval::LineNumbers(3)  User Contributed Perl Documentation Eval::LineNumbers(3)

NAME
       Eval::LineNumbers - Add line numbers to heredoc blocks that contain
       perl source code

SYNOPSIS
	use Eval::LineNumbers qw(eval_line_numbes);

	eval eval_line_numbers(<<END_HEREIS);
	  code
	END_HEREIS

	eval eval_line_numbers($caller_level, $code)

DESCRIPTION
       Add a "#line "this-file"	392" comment to	heredoc/hereis text that is
       going to	be eval'ed so that error messages will point back to the right
       place.

       Please note: when you embed "\n"	in your	code, it gets expanded in
       double-quote hereis documents so	it will	mess up	your line numbering.
       Use "\\n" instead when you can.

   Caller Level	Example
       The second form of eval_line_numbers where a caller-level is provided
       is for the situation where the code is generated	in one place and
       eval'ed in another place.  The caller level should be the number	of
       stack levels between where the heredoc was created and where it is
       eval'ed.

	sub example {
	  return <<END_HEREIS
	    code
       END_HEREIS
	}

	eval eval_line_numbers(1, example())
