=head1 NAME
Test::Inline::Content::Legacy - Test::Inline 2 Content Handler for legacy functions
=head1 SYNOPSIS
Custom script content generation using Test::Inline 2.000+ with a
custom generator functions
my $header = "....";
my $function = sub {
my $Object = shift;
my $Script = shift;
return $header . $Script->merged_content;
};
my $Inline = Test::Inline->new(
...
file_content => $function,
);
Migrating this same code to Test::Inline 2.100+ ContentHandler objects
my $header = "....";
my $function = sub {
my $Object = shift;
my $Script = shift;
return $header . $Script->merged_content;
};
my $ContentHandler = Test::Inline::Content::Legacy->new( $function );
my $Inline = Test::Inline->new(
...
ContentHandler => $ContentHandler,
);
=head1 DESCRIPTION
This class exists to provide a migration path for anyone using the custom
script generators in Test::Inline via the C<file_content> param.
The synopsis above pretty much says all you need to know.
=head1 METHODS
=cut
use strict;
use Params::Util qw{_CODE _INSTANCE};
use Test::Inline::Content ();
use vars qw{$VERSION @ISA};
BEGIN {
$VERSION = '2.212';
@ISA = 'Test::Inline::Content';
}
=pod
=head2 new $CODE_ref
The C<new> constructor for C<Test::Inline::Content::Legacy> takes a single
parameter of a C<CODE> reference, as you would have previously provided
directly to C<file_content>.
Returns a new C<Test::Inline::Content::Legacy> object, or C<undef> if not
passed a C<CODE> reference.
=cut
sub new {
my $class = ref $_[0] ? ref shift : shift;
my $self = $class->SUPER::new(@_);
$self->{coderef} = _CODE(shift) or return undef;
$self;
}
=pod
=head2 coderef
The C<coderef> accessor returns the C<CODE> reference for the object
=cut
sub coderef { $_[0]->{coderef} }
=pod
=head2 process $Inline $Script
The C<process> method works with the legacy function by passing the
L<Test::Inline> and L<Test::Inline::Script> arguments straight through
to the legacy function, and returning it's result as the return value.
=cut
sub process {
my $self = shift;
my $Inline = _INSTANCE(shift, 'Test::Inline') or return undef;
my $Script = _INSTANCE(shift, 'Test::Inline::Script') or return undef;
# Pass through the params, pass back the result
$self->coderef->( $Inline, $Script );
}
