NAME¶

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

VERSION¶

version 0.002011

SYNOPSIS¶

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

DESCRIPTION¶

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

PROVIDED METHODS¶

• 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.
