NAME

       Pod::Elemental::PerlMunger - a thing that takes a string of Perl and rewrites its
       documentation

VERSION

       version 0.200001

OVERVIEW

       This role is to be included in classes that rewrite the documentation of a Perl document,
       stripping out all the Pod, munging it, and replacing it into the Perl.

       The only relevant method is "munge_perl_string", which must be implemented with a
       different interface than will be exposed.

       When calling the "munge_perl_string" method, arguments should be passed like this:

         $object->munge_perl_string($perl_string, \%arg);

       $perl_string should be a character string containing Perl source code.

       %arg may contain any input for the underlying procedure.  The only key with associated
       meaning is "filename" which may be omitted.  If given, it should be the name of the file
       whose contents are being munged.

       The method will return a character string containing the rewritten and combined document.

       Classes including this role must implement a "munge_perl_string" that expects to be called
       like this:

         $object->munge_perl_string(\%doc, \%arg);

       %doc will have two entries:

         ppi - a PPI::Document of the Perl document with all its Pod removed
         pod - a Pod::Elemental::Document with no transformations yet performed

       This "munge_perl_string" method should return a hashref in the same format as %doc.

ATTRIBUTES

   replacer
       The replacer is either a method name or code reference used to produces PPI elements used
       to replace removed Pod.  By default, it is "replace_with_nothing", which just removes Pod
       tokens entirely.  This means that the line numbers of the code in the newly-produced
       document are changed, if the Pod had been interleaved with the code.

       See also "replace_with_comment" and "replace_with_blank".

       If no further code follows the Pod being replaced, "post_code_replacer" is used instead.

   post_code_replacer
       This attribute is used just like "replacer", and defaults to its value, but is used for
       building replacements for Pod removed after the last hunk of code.  The idea is that if
       you're only concerned about altering your code's line numbers, you can stop replacing
       stuff after there's no more code to be affected.

METHODS

   replace_with_nothing
       This method returns nothing.  It's the default "replacer".  It's not very interesting.

   replace_with_comment
       This replacer replaces removed Pod elements with a comment containing their text.  In
       other words:

         =head1 A header!

         This is great!

         =cut

       ...is replaced with:

         # =head1 A header!
         #
         # This is great!
         #
         # =cut

   replace_with_blank
       This replacer replaces removed Pod elements with vertical whitespace of equal line count.
       In other words:

         =head1 A header!

         This is great!

         =cut

       ...is replaced with five blank lines.
