nix.university's Introduction

nix.university

Click here to start a Codespace on nix.university/main
Open a Terminal ( Ctrl + Backtick ) and pick a path below.

nix repl

Type nix repl
Hit [Enter]
(Optionally, type university = import ./university.nix then hit [Enter] again)

nix-shell

Type nix-shell
Hit [Enter] (This loads shell.nix, which provides Emacs)

Important

If the above steps do not work as expected, then please reach out!

Note: including Nix language extensions in .devcontainer.json crashes the build, so they need to be installed afterward.

Nix internals

like this https://web.archive.org/web/20221001050043/https://comono.id/posts/2020-03-20-how-nix-instantiation-works/
nix usage of remote store as local (basically C++ code of nix which does nix diff and closures so nix does not care remoe or locl)
instantiate AGAIN

Nix for hardware and OS

QEMU storage formatter example
how to setup graphics card in NIX

not work with root

I try this:

{
  description = "Delta Chat for Android";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    rust-overlay.url = "github:oxalica/rust-overlay";
    flake-utils.url = "github:numtide/flake-utils";
    android.url = "github:tadfisher/android-nixpkgs";
  };

  outputs = { self, nixpkgs, rust-overlay, flake-utils, android }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        overlays = [ (import rust-overlay) ];
        pkgs = import nixpkgs { inherit system overlays; };
        android-sdk = android.sdk.${system} (sdkPkgs:
          with sdkPkgs; [
            build-tools-30-0-3
            cmdline-tools-latest
            ndk-bundle
            platform-tools
            platforms-android-33
            ndk-23-2-8568313
          ]);
      in {
        devShells.default = pkgs.mkShell {
          ANDROID_SDK_ROOT = "${android-sdk}/share/android-sdk";
          ANDROID_NDK_ROOT =
            "${android-sdk}/share/android-sdk/ndk/23.2.8568313";
	  shellHook = ''
            export PATH="$ANDROID_SDK_ROOT/build-tools/30.0.3/:$ANDROID_NDK_ROOT/toolchains/llvm/prebuilt/linux-x86_64/bin/:$PATH"
	  '';
          buildInputs = [
            android-sdk
            pkgs.openjdk17
            (pkgs.buildPackages.rust-bin.stable."1.72.0".minimal.override {
              targets = [
                "armv7-linux-androideabi"
                "aarch64-linux-android"
                "i686-linux-android"
                "x86_64-linux-android"
              ];
            })
          ];
        };
      });
}

I get the error every time and I have tried this hack:

NixOS/nix#6680 (comment)
