Hyfetch looking for a rust executable that doesn't exist?

[Qonstrukt]

Describe the bug

After updating to version 2.0.1 using Homebrew on macOS, I'm now greeted with the following message on every startup:

The rust executable is not found, falling back to python...

While showing this message every time in red seems a bit harsh, I figured I'd install rust and benefit from the performance improvements that should come with it. But after doing so with brew install rust it still complains.

I have no idea how Rust works or what it consists of, but I checked their website, and the closest thing to a "rust executable", seems to be rustc, but that is not what Hyfetch seems to be looking for. It wants a rust executable, but I can't find anything like that.

• Does this issue still occur in the master branch? (Required)

Expected behavior

No error messages about a "rust executable" on startup.

Config file

Please paste the content of ~/.config/hyfetch.json below:

{
    "preset": "rainbow",
    "mode": "rgb",
    "light_dark": "dark",
    "lightness": 0.65,
    "color_align": {
        "mode": "horizontal",
        "custom_colors": [],
        "fore_back": null
    },
    "backend": "neofetch",
    "args": null,
    "distro": null,
    "pride_month_shown": [],
    "pride_month_disable": false
}                                                                                                   

Additional context

Thanks for creating such a beautiful project ❤️ I think UX-wise this last release might need some polishing though. (Or at least some documentation for Rust n00bs like me.)

iirc rust does not need any external binaries to run something that is written in rust. do you have hyfetch installed with cargo?

cargo install hyfetch

[hykilpikonna]

Actually, I've already added the rust binary into the python pacakge, and during pip install it's supposed to install the wheel for your specific OS... idk why it's not working for you.

[hykilpikonna]

What platform are you using? Intel or M-series? And what's your version of macOS?

Just jumping in to say I am also affected on OpenBSD. Manually typing ~/.cargo/bin/hyfetch in my shell prompt lets the rust iteration run. But when ran from $PATH, it errors out with this:

Ok I think that is a different issue. OP is talking about python hyfetch (installed via pip) unable to find the rust hyfetch binary. Your issue is that rust hyfetch (installed via cargo) fails to find its own path when ran from PATH...

I also have no idea why this issue might exist, I'll have to look into it. Maybe should create a separate issue?

[Qonstrukt]

To clarify, I've installed HyFetch through Homebrew on macOS. I'm using the M-series platform on macOS 26.0 beta. So perhaps this is a packaging issue and I should contact that author?

That might be why. I checked the homebrew package seems to be using the non-platformed pypi package which doesn't have prebuilt hyfetch rust in it...

can you try again with pip install hyfetch?

[Qonstrukt]

That's not directly supported when running Homebrew:

❯ pip3 install hyfetch
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try brew install
    xyz, where xyz is the package you are trying to
    install.

When creating a venv and installing hyfetch in there it does seem to work okay without errors! 👍

Maybe @catumin or @osalbahr can elaborate on why it might not work directly from Homebrew?

I can confirm the line The rust executable is not found, falling back to python... appears when running hyfetch installed via Homebrew on my end, too. As to why that happens, I have no clue.

[osalbahr]

@Qonstrukt I found a workaround:

$ brew install --head hyfetch

Which uses cargo to install using the master branch. You will no longer see the error.

But, I don't know how upgrades would work. You might want to subscribe to the releases on GitHub.

[Qonstrukt]

Thanks for the workaround, not sure if I'll use that though. Sorry if I referenced you incorrectly, you are mentioned in the README for the Homebrew package. I might take a look at the recipe myself with the information gathered here.

prob because it's pulling 2.0.1.tar.gz instead of HyFetch-2.0.1-py3-none-macosx_11_0_x86_64.whl or HyFetch-2.0.1-py3-none-macosx_11_0_arm64.whl from pypi

[osalbahr]

Pulling the source code is, I believe, intended behavior because Homebrew creates the package from the source code.

It seems there is a missing dependency? Not sure.

Hmm okay you're right, idk then.
