VERSION

version 0.001003

SYNOPSIS

package Dist::Zilla::Plugin::Regenerate::SomeThing;
use Moose;
use Path::Tiny qw( path );
with "Dist::Zilla::Role::Plugin","Dist::Zilla::Role::Regenerator";

...
sub regenerate {
  my ( $self, $config ) = @_;
  path($config->{root}, 'CONTRIBUTING.pod')->spew_raw($content);
  path($config->{build_root}, 'META.json')->copy(path($config->{root}, 'META.json'));
}

DESCRIPTION

This role is for Dist::Zilla Plugin's that wish to fire under dzil regenerate

It is strongly recommended that this role not be lumped on randomly into packages that will operate at other phases.

IMPLEMENTATION

Consumers of this role MUST compose in Dist::Zilla::Role::Plugin at some stage, or at least, Dist::Zilla::Role::ConfigDumper.

Consumers of this rule MUST implement a method regenerate.

regenerate implementation

regenerate will be called as a method and passed a configuration hash.

{
    build_root => "path/to/where/dzil/build/writes/to"
    root       => "path/to/dzil/source/tree"
}

You may do with these as you wish, but recommended usage is to employ Path::Tiny to do one of the following:

• Write files directly from the plugin

  path($config->{root}, "CONTRIBUTING.pod")->spew_raw( ... );

  Keep in mind how file encoding works if you get your data from other parts of Dist::Zilla

• Copy files from the build tree

  path($config->{build_root}, "META.json")->copy($path->{root}, "META.json");

  ( Note: This case is implemented by [Regenerate] )

• (DON'T) Write files from zilla to disk

  How you'd do this is left to your imagination, but the details are ugly.

  Take note of the calls to _write_out_file in Dist::Zilla::Dist::Builder and the implementation details of _write_out_file in Dist::Zilla

  I suspect something like

  $self->zilla->_write_out_file( $self->zilla->files[0] , $config->{root} )

  Might kinda work, but keep in mind, that will spew if the file already exists.

  Good Luck Have Fun.

  Also, this approach is NOT recommended, because the final release image is NOT drafted from $self->zilla->files but from direct read of the $config->{build_root}.

  See Dist::Zilla/build_archive which has the call sequence:

  • ensure_built_in ...

  • write_out ...

  • -AfterBuild

  • -BeforeArchive

  • _build_archive ( from $write_out_dir )
