QRCode.zig

A "binding" of ricmoo/QRCode for Zig.

How to set it up

zig fetch --save git+https://github.com/darltrash/QRCode.zig

in your build.zig file:

const qrcode_pkg = b.dependency("qrcode", .{});
exe.root_module.addImport("qrcode", qrcode_pkg.module("qrcode"));

Example:

var qr = try QR.fromText(allocator, 1, .low, "HELLO WORLD!");
defer qr.deinit();

const stdout = std.io.getStdOut().writer();

for (0..qr.size) |y| {
    for (0..qr.size) |x| {
        const is_lit = qr.getModule(@intCast(x), @intCast(y));
        const characters = if (is_lit)
            "██"
        else
            "  ";

        try stdout.writeAll(characters);
    }

    try stdout.writeByte('\n');
}

Output:

██████████████  ████    ██  ██████████████
██          ██    ██    ██  ██          ██
