A fast, persistent implementation of direnv's use_nix and use_flake functions for Nix-based development environments. It caches nix-shell environments and protects build dependencies from garbage collection, replacing direnv's slower built-in implementation.

Use cases

  • speed up direnv with nix-shell environments
  • keep nix build dependencies from being garbage collected
  • set up automatic per-project nix flake environments
  • load nix development shell when entering a project directory
  • work offline with cached nix-shell environments
  • replace lorri with a simpler direnv integration

When to choose

  • you use direnv with Nix and want faster environment loading
  • you want persistent nix-shell caches that survive garbage collection
  • you need use_flake support in direnv without a background daemon

When to avoid

  • you don't use the Nix package manager
  • you need a direnv replacement rather than an enhancement
  • your system only has bash 3.2 and you cannot install a newer bash
