NAME

       Pandoc::Filter::Lazy - facilitate creation of filters

SYNOPSIS

         my $filter = Pandoc::Filter::Lazy->new(
             'Header => sub { Header $_->level, [ Str $_->string ] }'
         );
         if ( $filter->error ) {
             say STDERR $lazy->error;
             say STDERR $lazy->code;
         } else {
             $filter->apply(...)
         }

DESCRIPTION

       This module helps creation of Pandoc::Filter with arguments given as string.  The
       following should result in equivalent filters:

         Pandoc::Walker::action( ... );     #  ...  as code
         Pandoc::Filter::Lazy->new( '...' ) # '...' as string

       The script passed as only argument is tried to convert to valid Perl by escaping selectors
       and adding a missing "sub { ... }"", for instance

         Code|CodeBlock => say $_->class

       Is converted to

         'Code|CodeBlock' => sub { say $_->class }

METHODS

       In addition to the methods inherited from Pandoc::Filter:

   error
       Return an error message if compilation of the filter failed.

   script
       Return the (possibly cleaned) script arguments to create the filter.

   code( [ indent => $indent, ] [ function => $function ] )
       Return a string of Perl code that can be used to create the same filter.
