NAME ^

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

VERSION ^

version 0.002001

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.
