=head1 NAME

Perl::PrereqScanner::NotQuiteLite - a tool to scan your Perl code for its prerequisites

=head1 SYNOPSIS

  use Perl::PrereqScanner::NotQuiteLite;
  my $scanner = Perl::PrereqScanner::NotQuiteLite->new(
    parsers => [qw/:installed -UniversalVersion/],
    suggests => 1,
    perl_minimum_version => 1,
  );
  my $context = $scanner->scan_file('path/to/file');
  my $requirements = $context->requires;
  my $recommends = $context->recommends;
  my $suggestions  = $context->suggests; # requirements in evals
  my $noes = $context->noes;

=head1 DESCRIPTION

Perl::PrereqScanner::NotQuiteLite is yet another prerequisites
scanner. It passes almost all the scanning tests for
L<Perl::PrereqScanner> and L<Module::ExtractUse> (ie. except for
a few dubious ones), and runs slightly faster than PPI-based
Perl::PrereqScanner. However, it doesn't run as fast as
L<Perl::PrereqScanner::Lite> (which uses an XS lexer).

Perl::PrereqScanner::NotQuiteLite also recognizes C<eval>.
Prerequisites in C<eval> are not considered as requirements, but you
can collect them as suggestions.

Conditional requirements or requirements loaded in a block are
treated as recommends. Noed modules are stored separately (since 0.94).
You may or may not need to merge them into requires.

Perl::PrereqScanner::NotQuiteLite can also recognize some of
the new language features such as C<say>, subroutine signatures,
and postfix dereferences, to improve the minimum perl requirement
(since 0.9905).

=head1 METHODS

=head2 new

creates a scanner object. Options are:

=over 4

=item parsers

By default, Perl::PrereqScanner::NotQuiteLite only recognizes
modules loaded directly by C<use>, C<require>, C<no> statements,
plus modules loaded by a few common modules such as C<base>,
C<parent>, C<if> (that are in the Perl core), and by two keywords
exported by L<Moose> family (C<extends> and C<with>).

If you need more, you can pass extra parser names to the scanner,
or C<:bundled>, which loads and registers all the parsers bundled
with this distribution. If you have your own parsers, you can
specify C<:installed> to load and register all the installed parsers.

You can also pass a project-specific parser (that lies outside the 
C<Perl::PrereqScanner::NotQuiteLite::Parser> namespace) by
prepending C<+> to the name.

  use Perl::PrereqScanner::NotQuiteLite;
  my $scanner = Perl::PrereqScanner::NotQuiteLite->new(
    parsers => [qw/+PrereqParser::For::MyProject/],
  );

If you don't want to load a specific parser for some reason,
prepend C<-> to the parser name.

=item suggests

Perl::PrereqScanner::NotQuiteLite ignores C<use>-like statements in
C<eval> by default. If you set this option to true,
Perl::PrereqScanner::NotQuiteLite also parses statements in C<eval>,
and records requirements as suggestions.

=item recommends

Perl::PrereqScanner::NotQuiteLite usually ignores C<require>-like
statements in a block by default. If you set this option to true,
Perl::PrereqScanner::NotQuiteLite also records requirements in
a block as recommendations.

=item perl_minimum_version

If you set this option to true, Perl::PrereqScanner::NotQuiteLite
adds a specific version of perl as a requirement when it finds
some of the new perl language features.

=back

=head2 scan_file

takes a path to a file and returns a ::Context object.

=head2 scan_string

takes a string, scans and returns a ::Context object.

=head1 SEE ALSO

L<Perl::PrereqScanner>, L<Perl::PrereqScanner::Lite>, L<Module::ExtractUse>

L<Perl::PrereqScanner::NotQuiteLite::App> to scan a whole distribution.

L<scan-perl-prereqs-nqlite> is a command line interface of the above.
