Description

Simple, yet extensible, batteries-included Nix flake bootstrapping library for real-world projects with focus on building reproducible, portable binary artifacts for various targets efficiently and with little to no configuration.

Features

  • 0-config reproducible, portable binary artifacts
    • Cross-compilation out-of-the-box
    • Tiny OCI (Docker) images with statically-linked binaries out-of-the-box
  • Automatic per-system flake generation from a shared definition with consistent API
  • Source filtering

Usage

Generic flakes

nixify.lib.mkFlake provides the flake construction functionality that all other language specific subsystems rely upon. It can be used to build a plain Nix flake or a generic project in your language of choice.

Examples

Rust

nixify relies on two files to "Nixify" Rust projects:

  • Cargo.toml (required), where pname and version will be taken from. Note, that virtual manifests are supported as well.
  • rust-toolchain.toml (optional). If exists, nixify will set up the Rust toolchain using data contained in this file. For cross-compilation scenarios, nixify will automatically add missing targets to the toolchain.

Template

To nixify a Rust project:

nix flake init --template 'github:rvolosatovs/nixify#rust'

Examples

A flake definition at examples/rust-hello/flake.nix:

{
  inputs.nixify.url = github:rvolosatovs/nixify;

  outputs = {nixify, ...}:
    nixify.lib.rust.mkFlake {
      src = ./.;
    };
}

Produces the following outputs:

$ nix flake show --no-write-lock-file 'github:rvolosatovs/nixify?dir=examples/rust-hello'
