NAME
Perl::PrereqScanner::NotQuiteLite::App

SYNOPSIS
  scan-perl-prereqs-nqlite [options] [DIRS|FILES]

  -or-

  use Perl::PrereqScanner::NotQuiteLite::App;

  my $app = Perl::PrereqScanner::NotQuiteLite::App->new(
    parsers => [qw/:bundled/],
    suggests => 1,
    perl_minimum_version => 1,
  );
  my $prereqs = $app->run;

DESCRIPTION
Perl::PrereqScanner::NotQuiteLite::App walks down a directory and scans appropriate files to find prerequisites. You usually don't need to touch this module directly, but you might want to if you need finer control (to use a custom CPAN index etc).

METHODS

  new
creates an object. Notable options are:

parsers
    Perl::PrereqScanner::NotQuiteLite::App uses all the bundled parsers by default, but you can change if you need your own parsers. See Perl::PrereqScanner::NotQuiteLite for details.

recommends, suggests, perl_minimum_version
    Perl::PrereqScanner::NotQuiteLite::App usually returns "use"d modules only, but you can change this behavior by setting these options. See Perl::PrereqScanner::NotQuiteLite for details.

develop
    If set, Perl::PrereqScanner::NotQuiteLite::App also scans files under "xt" and "author" directories to find requirements for development.

exclude_core
    If set, Perl::PrereqScanner::NotQuiteLite::App ignores prerequisites that are bundled with Perl (of 5.008001 by default, or of a "use"d perl version if any). This requires Module::CoreList version 2.99 or above.

perl_version
    You can explicitly use this option to exclude core modules of a specific perl version.

allow_test_pms
    Perl::PrereqScanner::NotQuiteLite::App usually ignores ".pm" files under "t/" directory if they are not used in ".t" files, considering they are some kind of sample files. However, this assumption may be wrong sometimes. If this option is set, it scans all the ".pm" files under "t/" directory, considering some of the test modules will use them. If Test::Class (or its equivalent) is used in a test file, this option is implicitly set.

base_dir
    Perl::PrereqScanner::NotQuiteLite::App usually starts traversing from the current directory. If this option is set, it starts from there.

scan_also
    Perl::PrereqScanner::NotQuiteLite::App usually scans ".pm" files in the base dir, "Makefile.PL"/"Build.PL", files under "lib", "t", "bin", script(s) directories (and "xt", "author" if asked). If your distribution uses a different file layout, or uses extra directories to keep submodules, you can add (a reference to) a list of paths to scan.

ignore, ignore_re
    Your distribution may have OS-specific modules whose prerequisites can not be installed in other platforms. You can specify (a reference to) a list of files that should not be scanned (with "ignore" option), or a regular expression that matches the files (with "ignore_re" option).

features
      my $app = Perl::PrereqScanner::NotQuiteLite::App->new(
        features => {
          'windows' => {
            description => 'Windows support',
            paths => ['lib/Foo/Win32.pm'],
          }
        },
      );

    Instead of ignoring a set of files, you can use "features" option to let their prerequisites belong to a specific feature that will not be installed unless asked. However, you are advised to create a separate distribution for the specific feature.

optional, optional_re
    Instead of ignoring a set of files, you can also use "optional" option to mark all the prerequisites found in some of the files in your distribution optional (i.e. suggests). You can specify (a reference to) a list of files (with "optional" option), or a regular expression that matches the files (with "optional_re" option).

private, private_re
    Your distribution may use private modules that are not uploaded to the CPAN and thus should not be included in "cpanfile". You can specify (a reference to) a list of those private modules (with "private" option) or a regular expression that matches those modules (with "private_re" option).

use_index, index
    Perl::PrereqScanner::NotQuiteLite::App usually lists all the "use"d modules as prerequisites, but some of them may belong to the same distribution. If an instance of CPAN::Common::Index backend is passed, it is used to dedupe those prerequisites (as long as they are not versioned).

      use CPAN::Common::Index::LocalPackage;
      my $index = CPAN::Common::Index::LocalPackage->new(
        { source => "$ENV{HOME}/minicpan/modules/02packages.details.txt" }
      );
      my $app = Perl::PrereqScanner::NotQuiteLite::App->new(
        index => $index,
      );

  run
traverses files and directories and returns a CPAN::Meta::Prereqs object that keeps all the requirements/suggestions, without printing anything unless you explicitly pass a "print" option to "new".

  index
returns a CPAN::Common::Index backend object (if any).
