I disagree slightly with your narrative. A split pattern of  /(?m)\n(?=$)/ will split on any newline that is followed immediately by a newline (i.e., consequtive newlines) or on a newline at the end of the string (producing an empty string). This can be seen to be happening with modified text (and with a split LIMIT of -1 to preserve trailing null fields):

c:\@Work\Perl\monks>perl use strict; use warnings; use feature 'say'; my $s = <<'EOF'; int t; //variable t t->a=0; //t->a does;; something printf("\nEnter the Employee Name : "); scanf("%s", ptr->name); return 0; EOF for my $line (split/(?m)\n(?=$)/, $s, -1) { say '<' . $line . '>', "\n"; } __END__ <int t; //variable t t->a=0; //t->a does;; something> < printf("\nEnter the Employee Name : "); scanf("%s", ptr->name); return 0;> <>

I agree that the simplest and best approach is to split on what the OPer wants to split on, i.e., newlines, and forget about the  /m modifier and everything else.

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 How to display code and escape characters are good places to start.
