⛩️ Yae#

Yae is a simple dependency manager for use with Nix, similar to niv and npins.

I made it to solve my own problems, but I hope it can help you too.

Introduction#

You can try out Yae without installing anything permanently by running nix run github:Fuwn/yae.

Additionally, Tsutsumi uses Yae to manage dependencies. You can check out a working implementation there.

Usage#

View the installations instructions below to set up Yae after running yae init.

# Initialises a Yae environment in the current directory by creating an empty `yae.json`
# file
yae init

# Adds a Yae dependency named `zen-browser-twilight-bin` using a floating tag
# (tag always remain `twilight`, but may receive frequent hash changes)
yae add \
  --type binary \
  --version twilight \
  --unpack \
  zen-browser-twilight-bin \
  'https://github.com/zen-browser/desktop/releases/download/{version}/zen.linux-specific.tar.bz2'

# Adds a Yae dependency named `zen-browser-bin` pinned at tag `1.0.1-a.7`
yae add \
  --type git \
  --version 1.0.1-a.7 \
  --unpack \
  zen-browser-bin \
  'https://github.com/zen-browser/desktop/releases/download/{version}/zen.linux-specific.tar.bz2'

# Adds a Yae dependency named `yaak` pinned at tag `2024.10.1` with tag trimming for updates
yae add \
  --type git \
  --unpack=false \
  --version 2024.10.1 \
  --trim-tag-prefix v \
  yaak \
  'https://github.com/yaakapp/app/releases/download/v{version}/yaak_{version}_amd64.AppImage.tar.gz'

# Updates all dependencies, e.g., updates the hash of `zen-browser-twilight-bin`
# and bumps the version of `zen-browser-bin` to `1.0.1-a.8`, handling URL and
# hash recalculations, etc.
yae update

# Only updates `zen-browser-twilight-bin`
yae update zen-browser-twilight-bin

Installation#

Follow the installation instructions at Tsutsumi, which provides both flake and flake-less installation options.

Alternatively, without flake-less support, install the inputs.yae.packages.${pkgs.system}.yae package exposed by this flake.

Nix#

To add Yae support to your Nix expression after running yae init, just read from the Yae environment file.

Here's an example taken from Tsutsumi's zen-browser-bin package.

# pkgs/zen-browser-bin.nix

{
  pkgs,
  self,
  yae ? builtins.fromJSON (builtins.readFile "${self}/yae.json"),
}:
import "${self}/lib/zen-browser-bin.nix" {
  # Effortless dependency updates just by running `yae update` from CI using a
  # CRON job
  inherit (yae.zen-browser-bin) sha256 version;
} { inherit pkgs; }
