String::Diff

[ #31648 ]

I created String::Diff.
String::Diff is line diff tool, very simple.

  # simple diff
  my $diff = String::Diff::diff('this is Perl', 'this is Ruby');
  print "$diff->[0]\n";# this is [Perl]
  print "$diff->[1]\n";# this is {Ruby}

  my $diff = String::Diff::diff('this is Perl', 'this is Ruby',{
      remove_open => '<del>',
      remove_close => '</del>',
      append_open => '<ins>',
      append_close => '</ins>',
  });
  print "$diff->[0]\n";# this is <del>Perl</del>
  print "$diff->[1]\n";# this is <ins>Ruby</ins>

Algorithm::Diff is used.
thank you.

  • So you're tagging the content with XML? You didn't seem to hoist the rest of the document into XML though.

    • I misunderstood. Whoops. Here's how I'd use this: with Term::ANSIColor.

      use Term::ANSIColor 'color';
      my $diff = String::Diff::diff('this is Perl', 'this is Ruby',{
            remove_open => color( 'bold red' ),
            remove_close => color( 'reset' ),
            append_open => color( 'bold green' ),
            append_close => color( 'reset' ),
        });
