SYNOPSIS

use PPI::Transform::Sequence;
my $trans = PPI::Transform::Sequence->new(
  PPI::Transform::UpdateCopyright => [ name => 'Yasutaka ATARASHI' ],
  PPI::Transform::PackageName => [ -all => sub { s/^Acme\b/ACME/g } ],
);

print $trans->idx(0)->name; # access to PPI::Transform subclass object

# All PPI::Transform methods can be called, and
# Each transformation is sequentially applied.
$trans->file('Change.pm'); # Update copyright, then package names are replaced

DESCRIPTION

This module is a tiny binder to combine multiple PPI::Transform objects into one PPI::Transform object. You can combine them in-place without writing specific modules. Combined objects are sequentially applied.

METHODS

All of PPI::Transform methods are inherited.

new(list)

list is sequential pairs of a PPI::Transform subclass name and an array reference of constructor arguments. Even though there is no argument or only one argument, it is necessary to specify an array reference. The order of list is used as the application order of PPI::Transform objects.

idx(index)

Accessor of combined objects. index is a 0-based number in list, which are arguments of new.
