NAME

Dist::Zilla::Role::Tempdir - Shell Out and collect the result in a DZ plug-in.

VERSION

version 0.01053721

SYNOPSIS

package #
  Dist::Zilla::Plugin::FooBar;

use Moose;
with 'Dist::Zilla::Role::Tempdir';
with 'Dist::Zilla::Role::FileInjector';
with 'Dist::Zilla::Role::InstallTool';

sub setup_installer {
  my ( $self, $arg ) = @_ ;

  my ( @generated_files ) = $self->capture_tempdir(sub{
    system( $somecommand );
  });

  for ( @generated_files ) {
    if( $_->is_new && $_->name =~ qr/someregex/ ){
      $self->add_file( $_->file );
    }
  }
}

This role is a convenience role for factoring into other plug-ins to use the power of Unix in any plug-in.

If for whatever reason you need to shell out and run your own app that is not Perl ( i.e.: Java ) to go through the code and make modifications, produce documentation, etc, then this role is for you.

Important to note however, this role ONLY deals with getting Dist::Zilla's state written out to disk, executing your given arbitrary code, and then collecting the results. At no point does it attempt to re-inject those changes back into Dist::Zilla. That is left as an exercise to the plug-in developer.

METHODS

capture_tempdir

Creates a File::Tempdir and dumps the current state of Dist::Zilla's files into it.

Runs the specified code sub chdir'ed into that tmpdir, and captures the changed files.

my ( @array ) = $self->capture_tempdir(sub{

});

Response is an array of ::Tempdir::Item

[ bless( { name => 'file/Name/Here' ,
   status => 'O' # O = Original, N = New, M = Modified, D = Deleted
   file   => Dist::Zilla::Role::File object
 }, 'Dist::Zilla::Tempdir::Item' ) , bless ( ... ) ..... ]

Make sure to look at Dist::Zilla::Tempdir::Item for usage.

digest_for

my $hash = $self->digest_for( \$content );

Hashes content and returns the result in b64.

isa => Digest::base,
