Getty

Getty is a framework for building robust, optimal, and reusable (de)serializers in Zig.

• Compile-time (de)serialization.
• Out-of-the-box support for a variety of std types.
• Granular customization for existing and remote types.
• Data models that serve as simple and generic baselines for (de)serializers.

Quick Start

const std = @import("std");

pub fn build(b: *std.Build) void {
    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});

    const opts = .{ .target = target, .optimize = optimize };
    const json_mod = b.dependency("json", opts).module("json");

    const exe = b.addExecutable(.{
        .name = "quick-start",
        .root_source_file = .{ .path = "src/main.zig" },
        .target = target,
        .optimize = optimize,
    });

    exe.addModule("json", json_mod);

    const run_cmd = b.addRunArtifact(exe);
    const run_step = b.step("run", "Run the app");
    run_step.dependOn(&run_cmd.step);
}

.{
    .name = "quick-start",
    .version = "0.1.0",
    .paths = .{""},
    .dependencies = .{
        .json = .{
            .url = "https://github.com/getty-zig/json/archive/3e3cf7b.tar.gz",
            .hash = "122017ccb426b5f5690fdda438134852e940796b0ac619eb2648782a7879146f4fcd",
        },
    },
}

const std = @import("std");
const json = @import("json");

const ally = std.heap.page_allocator;

const Point = struct {
    x: i32,
    y: i32,
};

pub fn main() !void {
    const value = Point{ .x = 1, .y = 2 };

    // Serialize a Point value into JSON.
    const serialized = try json.toSlice(ally, value);
    defer ally.free(serialized);

    // Deserialize JSON data into a Point value.
    const deserialized = try json.fromSlice(ally, Point, serialized);

    // Print results.
    std.debug.print("{s}\n", .{serialized});  // {"x":1,"y":2}
    std.debug.print("{}\n", .{deserialized}); // main.Point{ .x = 1, .y = 2 }
}

Installation

1. Declare Getty as a project dependency with zig fetch:

   zig fetch --save git+https://github.com/getty-zig/getty.git#<COMMIT>
   

2. Expose Getty as a module in your project's build.zig:

   pub fn build(b: *std.Build) void {
       const target = b.standardTargetOptions(.{});
       const optimize = b.standardOptimizeOption(.{});
   
       const opts = .{ .target = target, .optimize = optimize };      // 👈
       const getty_mod = b.dependency("getty", opts).module("getty"); // 👈
   
       const exe = b.addExecutable(.{
           .name = "my-project",
           .root_source_file = .{ .path = "src/main.zig" },
           .target = target,
           .optimize = optimize,
       });
       exe.root_module.addImport("getty", getty_mod); // 👈
   
       // ...
   }
   

3. Import Getty into your code:

   const getty = @import("getty");
