Well, I can't comment on the C code, but I think you can make the Perl a bit clearer (or at least more correct). The following assumes that you want each <p>...</p> section on a new line. If not, the final join should be on an empty string.

sub MakePtag{ my $fixme = shift; # take in our parameters return join "\r\n", # join with newlines map { "<p>$_</p>" } # wrap each line in <p></p> tags grep { /\S/ } # must have at least one non-whitespace + character split "\r\n", $fixme; # break apart on the newlines }

Of course, I'd be shot for suggesting:

sub MakePtag { join "\r\n", map {"<p>$_</p>"} grep {/\S/} split "\r\n" +, $_[0] } # :)

If you stick with your solution, you'll want to chomp $fixme to avoid wasted tags on the end. Oh, and you had the slash on the trailing paragraph tag backwards :)

sub MakePtag{ chomp(my $fixme = shift;) # take in our parameters $fixme=~s|(\r\n)|</p><p>|g; # replace all \r\n with <\p><p> $fixme = "<p>$fixme</p>"; # Add beginning and ending tags return $fixme; }

Interesting question: what hoops would you have to just through with C to duplicate the grep functionality that I tossed in?
