git submodule integration

[Georges760]

Excellent job, it works on my machine too !!!

I had a couple of elf patching error but at the end I can compile....

I wonder how could we use your git repo as a esp-hal cargo project using git submodule maybe ?

If you flatten all files in the root of your repo, it could be used as a submodule just by creating a symlink to shell.nix from the root of the host repo (I guess).

That is great to hear! :) I also get ELF-patching warnings, it seems OK.

I haven't tried to package it as a submodule before, but if you are just looking for a 'portable' shell.nix you can use this one :) (this is the one I normally use).

{ pkgs ? import <nixpkgs> {}}:
let 
    esp-rs-src = builtins.fetchTarball "https://github.com/leighleighleigh/esp-rs-nix/archive/master.tar.gz";
    esp-rs = pkgs.callPackage "${esp-rs-src}/esp-rs/default.nix" {};
in
pkgs.mkShell rec {
    name = "esp-rs-nix";

    buildInputs = [
        esp-rs
        pkgs.rustup # I can't remember why I needed this 
        #pkgs.espflash # broken, install with cargo instead!
        pkgs.rust-analyzer
        pkgs.pkg-config 
        pkgs.stdenv.cc 
        pkgs.systemdMinimal
    ];

    shellHook = ''
    # optionally reload your bashrc to make the ugly nix-shell prompt go away 
    #. ~/.bashrc

    # this is important - it tells rustup where to find the esp toolchain,
    # without needing to copy it into your local ~/.rustup/ folder.
    export RUSTUP_TOOLCHAIN=${esp-rs}
    '';
}

thanks I like your shell.nix example ! may i ask where are you using it ?

[leighleighleigh]

I haven't got a public repo that uses it at the moment - but I've got several commercial projects using embassy-rs, which use a shell.nix file like that :)
