Nix Dev Shells

Overview

All development environments are managed through Nix Flakes, providing reproducible, composable toolsets per language. Enter any shell with:

nix develop .#<shell>

Base Tools (Every Shell)

Every shell includes a common set of CLI tools:

  • git, gh — version control and GitHub CLI
  • fzf — fuzzy finder
  • ripgrep — fast search
  • jq, yq — JSON/YAML processing
  • just — command runner
  • direnv — per-directory environment variables
  • chezmoi — dotfile management
  • tmux — terminal multiplexer
  • tree-sitter — incremental parsing
  • uv — Python package manager (available everywhere)

Usage with direnv

Projects use .envrc files with use flake .#<shell> to automatically activate the correct Nix shell when entering the directory:

# .envrc
use flake .#rust

Combined with direnv, this means the right tools are always available without manual shell activation.
