MooseX::AttributeHelpers::String
SYNOPSIS
package MyHomePage;
use Moose;
use MooseX::AttributeHelpers;
has 'text' => (
metaclass => 'String',
is => 'rw',
isa => 'Str',
default => sub { '' },
provides => {
append => "add_text",
replace => "replace_text",
}
);
my $page = MyHomePage->new();
$page->add_text("foo"); # same as $page->text($page->text . "foo");
DESCRIPTION
This module provides a simple string attribute, to which mutating
string operations can be applied more easily (no need to make an lvalue
attribute metaclass or use temporary variables). Additional methods are
provided for completion.
If your attribute definition does not include any of is, isa, default
or provides but does use the "String" metaclass, then this module
applies defaults as in the "SYNOPSIS" above. This allows for a very
basic counter definition:
has 'foo' => (metaclass => 'String');
$obj->append_foo;
METHODS
meta
method_provider
has_method_provider
helper_type
process_options_for_provides
Run before its superclass method.
check_provides_values
Run after its superclass method.
PROVIDED METHODS
It is important to note that all those methods do in place modification
of the value stored in the attribute.
inc Increments the value stored in this slot using the magical string
autoincrement operator. Note that Perl doesn't provide analogeous
behavior in "--", so "dec" is not available.
append $string
Append a string, like ".=".
prepend $string
Prepend a string.
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.
match $pattern
Like replace but without the replacement. Provided mostly for
completeness.
"chop"
"chop" in perlfunc
"chomp"
"chomp" in perlfunc
"clear"
Sets the string to the empty string (not the value passed to
"default").
BUGS
All complex software has bugs lurking in it, and this module is no
exception. If you find a bug please either email me, or add the bug to
