SYNOPSIS¶

  package MyHomePage;
  use Mouse;
  has 'text' => (
      traits    => ['String'],
      is        => 'rw',
      isa       => 'Str',
      default   => q{},
      handles   => {
          add_text     => 'append',
          replace_text => 'replace',

  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.

PROVIDED METHODS¶

These methods are implemented in MouseX::NativeTraits::MethodProvider::Str. 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 analogous 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). A code references will be accepted for the replacement, causing the regexp to be modified with a single "e". "/smxi" can be applied using the "qr" operator.

replace($pattern, $replacement)

Performs a regexp substitution ("s" in perlop) with the "g" flag. A code references will be accepted for the replacement, causing the regexp 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").

length

"length" in perlfunc

substr

"substr" in perlfunc. We go to some lengths to match the different functionality based on "substr"'s arity.
