Dist::Zilla::Role::PPI(3pm) User Contributed Perl Documentation Dist::Zilla::Role::PPI(3pm)


Dist::Zilla::Role::PPI - a role for plugins which use PPI


version 6.024


This role provides some common utilities for plugins which use PPI.


This module should work on any version of perl still receiving updates from the Perl 5 Porters. This means it should work on any version of perl released in the last two to three years. (That is, if the most recently released version is v5.40, then this module should work on both v5.40 and v5.38.)

Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.



  my $document = $self->ppi_document_for_file($file);

Given a dzil file object (anything that does Dist::Zilla::Role::File), this method returns a new PPI::Document for that file's content.

Internally, this method caches these documents. If multiple plugins want a document for the same file, this avoids reparsing it.


  my $document = $self->save_ppi_document_to_file($document,$file);

Given a PPI::Document and a dzil file object (anything that does Dist::Zilla::Role::File), this method saves the serialized document in the file.

It also updates the internal PPI document cache with the new document.


  if( $self->document_assigns_to_variable($document, '$FOO')) { ... }

This method returns true if the document assigns to the given variable (the sigil must be included).
