nix-zsh-env

Prints a compact label describing the active Nix shells, meant for a zsh precmd:

nix_info=$(nix-zsh-env)
[[ -n $nix_info ]] && nix_prompt="[${nix_info}]"

Active shells	Output
none	(empty)
nix-shell -p jq ripgrep	λjq:ripgrep
nix develop	❄
both	❄λjq:ripgrep

Each environment is a ShellScenario variant with a ShellDetector that inspects the environment. ActiveShells runs every detector, so more than one scenario can be active at once. To support a new environment, add a variant and its render arm to ShellScenario and a detector to shell_detectors in src/nix-zsh-env.zig.
