NAME
    Tangerine - Analyse perl files and report module-related information

SYNOPSIS
        use Tangerine;
        use version 0.77;

        my $scanner = Tangerine->new(file => $file, mode => 'all');
        $scanner->run;

        print "$file contains the following modules: ".
            join q/, /, sort keys %{$scanner->provides}."\n";

        print "$file requires Exporter on the following lines: ".
            join q/, /, sort map $_->line, @{$scanner->requires->{Exporter}}."\n";

        my $v = 0;
        for ( @{$scanner->uses->{Test::More}}) {
            $v = $_->version if $_->version && qv($v) < qv($_->version)
        }
        print "The minimum version of Test::More required by $file is $v\n";

DESCRIPTION
    Tangerine statically analyses perl files and reports various information
    about provided, used (compile-time dependencies) and required (runtime
    dependencies) modules.

    Currently, PPI is used for the initial parsing and statement extraction.

CONSTRUCTOR
    "new"
        Creates the Tangerine object. Takes the following two named
        arguments:

            'file', the file to analyse
            'mode', what should we look for; may be one of 'all', 'prov', 'dep',
                'req' or 'use'.  'dep' implies both 'req' and 'use'.  Single
                letter abbreviations are also accepted.

        Both arguments are optional, however, 'file' needs to be set before
        running the scanner, e.g.

            my $scanner = Tangerine->new;
            $scanner->file($file);
            $scanner->run;

METHODS
    "run"
        Runs the analysis.

    "provides"
        Returns a hash reference. Keys are the modules provided, values
        references to lists of Tangerine::Occurence objects.

    "requires"
        Returns a hash reference. Keys are the modules required at run-time,
        values references to lists of Tangerine::Occurence objects.

    "uses"
        Returns a hash reference. Keys are the modules required at
        compile-time, values references to lists of Tangerine::Occurence
        objects.
