# pi_modern_shell_env

Installs modern CLI tooling (fish, ripgrep, fd, bat, fzf, zoxide, lsd,
tmux) plus an oh-my-posh prompt for the login user on `iot` Pi hosts, and
makes fish the default login shell. Purely a convenience layer for
interactive SSH sessions into otherwise single-purpose appliance boxes —
does not affect any of the audio/sensor services these hosts run.

The oh-my-posh theme (`files/ohmyposh.json`) and its fish vi-mode
integration (`templates/config.fish.j2`) are copied from the same setup
used in `~/nixconfig`'s home-manager config
(`homeManagerModules/cli/modern-cli.nix`/`ohmyposh.json`), so the prompt
looks and behaves the same on the desktop and on these Pis. If that
nixconfig theme changes, re-sync `files/ohmyposh.json` here by hand — the
two aren't linked.

**Key vars:**

- `pi_modern_shell_env_target_user` — user to configure (defaults to
  `main_user`, falling back to `root`).
- `pi_modern_shell_env_set_default_shell` — whether to `chsh` the target
  user to fish (default `true`).
