How do i install it? #61

prajwalch · 2021-12-13T02:34:02Z

Hi i am new to zig and i would like to use this library for my project. But I don't see any install instructions on README so idk how can i use it.

Hejsil · 2021-12-13T15:06:26Z

Edit: Yo, it's me from the year 2024. Zig now has a package manager and the readme should now instruct users on how to install zig-clap. If the instructions are still unclear, do comment here so it can be improved 👍

Original comment:

Right now, there is no standard way to install Zig libraries. There are a few common ways people do it:

git submodule or copying and pasting the library into their own project
- After this, you can add exe.addPackagePath("clap", "path/to/clap.zig"); to your build.zig file to use the library
Use an unofficial package manager such as zigmod or gyro
- Look at the docs for these package managers for how to install packages using them. They should both be able to install zig-clap as far as I know.

Hope this helps. I'll leave this issue open until Zig has an official package solution. I can then make the choice to add something to the README or not.

Thank you.
I decided to use it by using git submodule.

If anyone has a same issue as me here's how you can use it.

On your project root directory make a directory name libs.
Run git submodule add https://github.com/Hejsil/zig-clap libs/zig-clap
Then add exe.addPackagePath("clap", "libs/zig-clap/clap.zig") on your build.zig
Now you can import clap on your source file as const clap = @import("clap");

Sorry, but currently how do I do this ? exe.addPackagePath didn't seem to work.
Should I just read more on the package manager ?

This used to work so i am not sure whether this will work or not nowadays but you can try.
Ping me if that doesn't work ;)

exe.addAnonymousModule("zig-clap", .{
    .source_file = .{ .path = "libs/zig-clap/clap.zig" },
});

punowo · 2023-06-05T18:18:21Z

exe.addAnonymousModule("zig-clap", .{
    .source_file = .{ .path = "libs/zig-clap/clap.zig" },
});

That works. Thank you.

You can also now try out the zig package manager:

build.zig.zon

.{
    .name = "name-of-my-program-or-package",
    .version = "0.0.0",
    .dependencies = .{
        .clap = .{
            .url = "https://github.com/Hejsil/zig-clap/archive/<git-hash-or-version>.tar.gz",
            .hash = "<the-hash-zig-tells-you-the-package-has>",
        },
    }
}

build.zig

const clap = b.dependecy("clap", .{});
exe.addModule("clap", clap.module("clap"));

Or, if you need multiple things to depend on clap but not use the package manager:

const clap = b.createModule(.{
    .source_file = .{ .path = "lib/zig-clap/clap.zig" },
});
exe.addModule("clap", clap);

build.zig.zon

.{
    .name = "name-of-my-program-or-package",
    .version = "0.0.0",

        .clap = .{
            .url = "https://github.com/Hejsil/zig-clap/archive/<git-hash-or-version>.tar.gz",
            .hash = "<the-hash-zig-tells-you-the-package-has>",
        },
    }
}

@Hejsil how do I make zig tell me that?

.{ .name = "themepak", .version = "0.1.0", .dependencies = .{
    .clap = .{
        .url = "https://github.com/Hejsil/zig-clap/archive/34e068756e69e7ee51ba6f27eb9036e19984a128.tar.gz",

Oh I got it, first comment or remove .hash = ..., line, then run zig build, it'll will then tell you.

Yup that's right.

How to resolve this issue?

Hejsil · 2024-01-09T09:39:31Z

@rawhuul Version 0.7 of zig-clap targets 0.11 of zig. There is no guarantee that this version will work with newer version of zig. Seems you're very close to zig master, so you should get a master version of zig clap as well.

OKay I will try with master version

MathewDeyo · 2024-03-11T21:19:18Z

Any insight on using the Zig Package Manager?

$ zig version
0.12.0-dev.3212+40e64245f

build.zig.zon:

.{
    .name = "package-name-here",
    .version = "0.0.0",
    .dependencies = .{
        .clap = .{
            .url = "https://github.com/Hejsil/zig-clap/archive/refs/heads/master.tar.gz",
            .hash = "12203896de6eedec14712f4f1eaac8b646939cfed213c56accf231a0abb05f9dbb77",
         },
    },
    .paths = .{
        "",
    },
}

build.zig:

const clap = b.dependency("clap", .{});
exe.root_module.addImport("clap", clap.module("clap"));
exe.linkLibrary(clap.artifact("clap"));

And when I try to zig build:

$ zig build

If I remove exe.linkLibrary(clap.artifact("clap"));, the build works, but I can't run the application:

$ zig run src/main.zig -- -h
src\main.zig:2:22: error: no module named 'clap' available within module main
const clap = @import("clap");
                     ^~~~~~

    callMain: C:\Users\user\.zvm\master\lib\std\start.zig:511:32
    remaining reference traces hidden; use '-freference-trace' to see all reference traces

I've tried using Zig 0.11.0 with tag 0.7.0 as well (and converted the build.zig file to match) with basically the same results:

$ zig run src/main.zig -- -h
src\main.zig:2:22: error: no package named 'clap' available within package 'root'
const clap = @import("clap");
                     ^~~~~~

Hejsil · 2024-03-11T22:27:13Z

@MathewDeyo

You have the right code in build.zig after you removed exe.linkLibrary(clap.artifact("clap"));. The problem you're hitting now is that zig run doesn't use the build system. Only zig build actually looks at build.zig. I don't think this issue is a place for a zig tutorial so please ask in any of the zig communities for help and advice :)

kothavade · 2024-05-24T04:17:53Z

In Zig 0.12 it seems like the way to do this is now (new to Zig, so this may be wrong, but it's working for me):

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

janie314 · 2024-06-03T00:18:53Z

To summarize:

(1) Run this:

zig fetch --save git+https://github.com/Hejsil/zig-clap

(2) Then add @kothavade 's suggestion in build.zig:

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

Yeag this sould probably be improved.

Happy Zigging.

Hi I'm on OS X Ventura 13.6.9 and use zig 0.13.0.
I did exactly as said here and in the readme but I'm unable to build a simple "hello world" project.
When i do zig build I get this:

...
error: root struct of file 'Build.Step' has no member named 'MakeOptions'
            fn make(step: *std.Build.Step, _: std.Build.Step.MakeOptions) anyerror!void {

This is what i have in my build.zig.zon:

    .dependencies = .{
        .clap = .{
            .url = "git+https://github.com/Hejsil/zig-clap#de916df4982807d48ae497df0d75d6324b69a71a",
            .hash = "...long hash here...",
        },
    },

I'm fairly new to Zig, so I don't understand where that MakeOptions come from.
~~Any clue?~~

EDIT

Nevermind, i did this:

change dependencies to use the 0.9.1 release:

.dependencies = .{
        .clap = .{
            .url = "https://github.com/Hejsil/zig-clap/archive/refs/tags/0.9.1.tar.gz",
            ...
        },
    },

commented my hash row below .url = "..."
zig build which failed
copied and pasted the expected .hash = ... that zig build gave me when failed

And it worked.

The installation section no longer assumes that all developers use the master branch of Zig. Instead if provides different steps depending on which Zig version developers are using. Related #61

Hejsil · 2024-09-16T14:57:16Z

@microspino Seems the readme still needed a bit of work. While it did mention that the master branch of zig-clap targets the master branch of Zig, this wasn't under the installation section and therefor easily missed. I've rewritten the installation section to explain how to install zig-clap both for people who use a tagged release of Zig and Zig master.

Hopefully that should avoid the dance you did for others :)
