NAME

File::Find::Rule::Perl - Common rules for searching for Perl things

SYNOPSIS

  use File::Find::Rule       ();
  use File::Find::Rule::Perl ();
  
  # Find all Perl files smaller than 10k
  my @files = File::Find::Rule->perl_file
                              ->size('<10Ki')
                              ->in('dir');
  
  # Locate all the modules that PAUSE will index
  my @mod = File::Find::Rule->no_index
                            ->perl_module
                            ->in('My-Distribution');

DESCRIPTION

I write a lot of things that muck with Perl files. And it always annoyed me that finding "perl files" requires a moderately complex File::Find::Rule pattern.

File::Find::Rule::Perl provides methods for finding various types Perl-related files, or replicating search queries run on a distribution in various parts of the CPAN ecosystem.

METHODS

perl_module

The "perl_module" rule locates perl modules. That is, files that are named "*.pm".

This rule is equivalent to "->"file->name( '*.pm' )> and is included primarily for completeness.

perl_test

The "perl_test" rule locates perl test scripts. That is, files that are named "*.t".

This rule is equivalent to "->"file->name( '*.t' )> and is included primarily for completeness.

perl_installer

The "perl_installer" rule locates perl distribution installers. That is, it locates "Makefile.PL" and "Build.PL" files.

perl_script

The "perl_script" rule locates perl scripts.

This is any file that ends in .pl, or any files without extensions that have a perl "hash-bang" line.

perl_file

The "perl_file" rule locates all files containing Perl code.

This includes all the files matching the above "perl_module", "perl_test", "perl_installer" and "perl_script" rules.

no_index

  # Provide the rules directly
  $rule->no_index(
      directory => [ 'inc', 't', 'examples' ],
      file      => [ 'Foo.pm', 'lib/Foo.pm' ],
  );
  
  # Provide a META.yml to use
  $rule->no_index( 'META.yml' );
  
  # Provide a dist root directory to look for a META.yml in
  $rule->no_index( 'My-Distribution' );
  
  # Automatically pick up a META.yml from the target directory
  $rule->no_index->in( 'My-Distribution' );

The "no_index" method applies a set of rules as per the no_index section in a "META.yml" file.
