Wuffs file loading library packaged for zig

Usage

For zig 0.13.0, packages wuffs version 0.4.0-alpha.9+3837.20240914

zig fetch --save=wuffs git+https://github.com/allyourcodebase/wuffs

Then, choose one:

Option 1: Statically linking wuffs

build.zig:

const wuffs = b.dependency("wuffs", .{.target = target, .optimize = optimize});
exe.linkLibrary(wuffs.artifact("wuffs"));

c:

#include <wuffs.h>

Option 2: Using from zig with automatic translate-c bindings

build.zig:

const wuffs = b.dependency("wuffs", .{.target = target, .optimize = optimize});
exe.root_module.addImport("wuffs", wuffs.module("wuffs"));

zig:

const wuffs = @import("wuffs");

Option 3: Using in one file from C without exporting any symbols:

build.zig:

const wuffs = b.dependency("wuffs", .{.target = target, .optimize = optimize});
exe.addIncludePath(wuffs.b.dependency("wuffs", .{}).path("release/c"));

c:

#define WUFFS_CONFIG__STATIC_FUNCTIONS
#define WUFFS_IMPLEMENTATION
#include <wuffs-v0.4.c>

// wuffs functions can be used in this file only and do not leak any symbols outside this file

Notes

This package is for using the wuffs standard library. It downloads a prebuilt .c file, and does not package the wuffs compiler itself for use with zig.
