SYNOPSIS

    use v5.24;
    use CPANfile::Parse::PPI;
    
    my $path     = '/path/to/cpanfile';
    my $cpanfile = CPANfile::Parse::PPI->new( $path );
    
    # or

    for my $module ( $cpanfile->modules->@* ) {
        my $stage   = $module->{stage}   ? " on $module->{stage}"            : '';
        my $feature = $module->{feature} ? " for feature $module->{feature}" : '';

        say sprintf "%s is %s",
             $module->{name}, $module->{type}, $stage, $feature;
    }

METHODS

new

    my $path     = '/path/to/cpanfile';
    my $cpanfile = CPANfile::Parse::PPI->new( $path );
    
    # or
    my $content  = <<'CPANFILE';
    requires "CPANfile::Parse::PPI" => 3.6;';
    on build => sub {
        recommends "Dist::Zilla" => 4.0;
        requires "Test2" => 2.311;
    }
    feature 'sqlite', "SQLite Support" => sub {
        requires DBD::SQLite
    }
    CPANFILE

    my $cpanfile = CPANfile::Parse::PPI->new( \$content );

ATTRIBUTES

meta

Returns information about mirrors and OS name - if given in the cpanfile

modules

Returns a list of modules mentioned in the cpanfile ("perl" is skipped). Each element is a hashref with these keys:

• name

• version

• type

• stage

• feature

    use CPANfile::Parse::PPI;
    use Data::Printer;

    my $required = 'requires "CPANfile::Parse::PPI" => 3.6;';
    my $cpanfile = CPANfile::Parse::PPI->new( \$required );
    
    my $modules = $cpanfile->modules;
    p $modules;
    
    __DATA__
    [
        [0] {
            name      "CPANfile::Parse::PPI",
            stage     "",
            type      "requires",
            version   3.6
        }
    ]

LIMITATIONS

As this is a static parser, this module cannot handle dynamic code like

    for my $module (qw/
        IO::All
        Zydeco::Lite::App
    /) {
        requires $module, '0';
    }

This module warns when the required "module" doesn't look like a package name.

You can make it die when you pass -strict to the module when you load it:

    use CPANfile::Parse::PPI -strict;
    use Data::Printer;

    my $required = do { local $/; <DATA> };
    my $cpanfile = CPANfile::Parse::PPI->new( \$required );
    
    my $modules = $cpanfile->modules;
    
    __DATA__
    for my $module (qw/
        IO::All
        Zydeco::Lite::App
    /) {
        requires $module, '0';
    }
