Zig String (A UTF-8 String Library)
This library is a UTF-8 compatible string library for the Zig programming language. I made this for the sole purpose to further my experience and understanding of zig. Also it may be useful for some people who need it (including myself), with future projects. Project is also open for people to add to and improve. Please check the issues to view requested features.
Basic Usage
const std = @import("std");
const String = @import("./zig-string.zig").String;
// ...
// Use your favorite allocator
var arena = std.heap.ArenaAllocator.init(std.heap.page_allocator);
defer arena.deinit();
// Create your String
var myString = String.init(arena.allocator());
defer myString.deinit();
// Use functions provided
try myString.concat("🔥 Hello!");
_ = myString.pop();
try myString.concat(", World 🔥");
// Success!
std.debug.assert(myString.cmp("🔥 Hello, World 🔥"));
Installation
Add this to your build.zig.zon
.dependencies = .{
.string = .{
.url = "https://github.com/JakubSzark/zig-string/archive/refs/heads/master.tar.gz",
//the correct hash will be suggested by zig
}
}
And add this to you build.zig
const string = b.dependency("string", .{
.target = target,
.optimize = optimize,
});
exe.root_module.addImport("string", string.module("string"));
You can then import the library into your code like this
const String = @import("string").String;
