Nixtamal

Nixtamal is an input pinner for Nix projects.

Automate the manual work of input pinning for dependency management
Allow easy ways to lock & refresh those inputs
Declarative KDL manifest file over imperative CLI flags
diff/grep-friendly lockfile
Declarative patch/diff management for inputs
Host-, forge-, VCS-agnostic
Choose eval time fetchers (builtins) or build time fetchers (Nixpkgs, default) — which opens up fetching now-supported Darcs, Pijul, & Fossil
Supports mirrors, failing over when a server is down
Override hash algorithm on a per-project & per-input basis — including BLAKE3 support ^[1]
Custom freshness commands
Blueprints for opinionated, stable-Nix-compatible, base project structure setup
No experimental Nix features required

↑ Opting in requires enabling blake3-hashes experimental feature which requires Nix 2.31+
