Data::Perl::Role::String - Wrapping class for Perl scalar strings.

version 0.002011

  use Data::Perl qw/string/;
  my $string = string("foo\n");
  $string->chomp; # returns 1, $string == "foo"

This class provides a wrapper and methods for interacting with scalar strings.

  • new($value)

    Constructs a new Data::Perl::String object, optionally initialized to $value if passed in, and returns it.

  • inc

    Increments the value stored in this slot using the magical string autoincrement operator. Note that Perl doesn't provide analogous behavior in "--", so "dec" is not available. This method returns the new value.

    This method does not accept any arguments.

  • append($string)

    Appends to the string, like ".=", and returns the new value.

    This method requires a single argument.

  • prepend($string)

    Prepends to the string and returns the new value.

    This method requires a single argument.

  • replace($pattern, $replacement)

    Performs a regexp substitution ("s" in perlop). There is no way to provide the "g" flag, but code references will be accepted for the replacement, causing the regex to be modified with a single "e". "/smxi" can be applied using the "qr" operator. This method returns the new value.

    This method requires two arguments.

  • match($pattern)

    Runs the regex against the string and returns the matching value(s).

    This method requires a single argument.

  • chop

    Just like "chop" in perlfunc. This method returns the chopped character.

    This method does not accept any arguments.

  • chomp

    Just like "chomp" in perlfunc. This method returns the number of characters removed.

    This method does not accept any arguments.

  • clear

    Sets the string to the empty string (not the value passed to "default").

    This method does not have a defined return value.

    This method does not accept any arguments.

  • length

    Just like "length" in perlfunc, returns the length of the string.

  • substr

    This acts just like "substr" in perlfunc. When called as a writer, it returns the substring that was replaced, just like the Perl builtin.

    This method requires at least one argument, and accepts no more than three.

  • Data::Perl
  • MooX::HandlesVia
