App::FuguSeed::Text(3p) Perl Library Manual App::FuguSeed::Text(3p)

App::FuguSeed::Text - the views of a Standard SeedQR

    use App::FuguSeed::Text;
    print App::FuguSeed::Text->grid($matrix);
    for my $view (App::FuguSeed::Text->zones($matrix)) {
            print $view;
    }

App::FuguSeed::Text renders the matrix of App::FuguSeed::Matrix as text. A dark module prints as "#", and a light module prints as ".". One character is one module.

The grid view holds the 25 rows, with one space between the zone columns and one empty line between the zone rows. The letters A to E label the rows of zones, and the numbers 1 to 5 label the columns of zones. A zone is 5 x 5 modules, and zone "A-1" is the top left zone. The names are the names that SeedSigner shows.

A zone view holds the zone name, the 5 rows of the zone, and the count of the dark modules of the zone. A person draws one zone at a time, and the count proves the work.

Each view starts with one empty line and ends with one line feed, and no line carries a trailing space.

Every method is a class method, and every method is pure: it takes values and it returns values. The module touches no stream, and it loads no module.

grid($matrix) returns the grid view of the matrix as one string.

zones($matrix) returns the 25 zone views, in the order "A-1" to "E-5". Each view is one string.

grid() returns one string. zones() returns 25 strings.

grid() and zones() expect the matrix of App::FuguSeed::Matrix: 25 rows of 25 modules.

App::FuguSeed::Matrix, App::FuguSeed::QR, and "fuguseed-qr(1)".
