=head1 NAME
Data::Perl::Role::String - Wrapping class for Perl scalar strings.
=head1 VERSION
version 0.002009
=head1 SYNOPSIS
use Data::Perl qw/string/;
my $string = string("foo\n");
$string->chomp; # returns 1, $string == "foo"
=head1 DESCRIPTION
This class provides a wrapper and methods for interacting with scalar strings.
=head1 PROVIDED METHODS
=over 4
=item * B<new($value)>
Constructs a new Data::Perl::String object, optionally initialized to $value if
passed in, and returns it.
=item * B<inc>
Increments the value stored in this slot using the magical string autoincrement
operator. Note that Perl doesn't provide analogous behavior in C<-->, so
C<dec> is not available. This method returns the new value.
This method does not accept any arguments.
=item * B<append($string)>
Appends to the string, like C<.=>, and returns the new value.
This method requires a single argument.
=item * B<prepend($string)>
Prepends to the string and returns the new value.
This method requires a single argument.
=item * B<replace($pattern, $replacement)>
Performs a regexp substitution (L<perlop/s>). There is no way to provide the
C<g> flag, but code references will be accepted for the replacement, causing
the regex to be modified with a single C<e>. C</smxi> can be applied using the
C<qr> operator. This method returns the new value.
This method requires two arguments.
=item * B<match($pattern)>
Runs the regex against the string and returns the matching value(s).
This method requires a single argument.
=item * B<chop>
Just like L<perlfunc/chop>. This method returns the chopped character.
This method does not accept any arguments.
=item * B<chomp>
Just like L<perlfunc/chomp>. This method returns the number of characters
removed.
This method does not accept any arguments.
=item * B<clear>
Sets the string to the empty string (not the value passed to C<default>).
This method does not have a defined return value.
This method does not accept any arguments.
=item * B<length>
Just like L<perlfunc/length>, returns the length of the string.
=item * B<substr>
This acts just like L<perlfunc/substr>. 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.
