nix-conf

My personal nix configuration.

Installing nix

Darwin

Install Deterministic Nix curl -fsSL https://install.determinate.systems/nix | sh -s -- install

Linux

Use the multiuser installer

sh <(curl --proto '=https' --tlsv1.2 -L https://nixos.org/nix/install) --daemon

Setup this home-manager config

nix run home-manager/master -- --init switch

rm -rf ~/.config/home-manager

git clone git@github.com:davebenvenuti/home-manager.git ~/.config/home-manager

Apply

Assuming the hostnames are set properly (air or shithouse),

home-manager switch

If they're not set, you can switch to individual configurations by doing

home-manager switch --flake .#dave@air

If you get an error about clobber files, run

home-manager switch -b hmbackup

Uninstalling Nix

Darwin

/nix/nix-installer uninstall

Linux

See Nix Reference Manual | Uninstalling Nix

Notes

home-manager was initialized with nix run home-manager/master -- init --switch. This created ~/.config/home-manager.

Zshrc.private Sync System

This configuration includes a system to securely sync your ~/.zshrc.private file to Bitwarden. This file is meant for sensitive environment variables, API keys, and other secrets that shouldn't be committed to version control.

How it works:

1. Prompt Indicator: A yellow asterisk (*) appears in your zsh prompt when ~/.zshrc.private has been modified but not yet synced to Bitwarden.

2. Sync Command: Run sync-zshrc-private to upload the current version to Bitwarden as a secure note. The note is named .zshrc.private (HOSTNAME).

3. Status Check: Use zshrc-private-status to check if your file is synced without syncing.

4. Manual Refresh: If needed, run refresh-zsh-prompt to immediately update the prompt indicator.

Setup:

1. Ensure Bitwarden CLI is installed and configured (bw command available)
2. Run bw login to log into your Bitwarden account
3. Run bw unlock to unlock your vault and get a session key
4. Set the session key as an environment variable:

   export BW_SESSION="$(bw unlock --raw)"
   

   (Consider adding this to your shell configuration)

Files:

• ~/.zshrc.private: Your private shell configuration (not tracked in git)
• ~/.zshrc.private.lastsync: Stores the hash of the last synced version
• ~/.local/bin/sync-zshrc-private.sh: Sync script
• ~/.local/share/zsh/zshrc-private-sync.zsh: Zsh plugin for prompt integration

How the prompt indicator updates:

The indicator is part of the PROMPT string itself ($(_zshrc_private_prompt_indicator)), so it's evaluated each time the prompt is displayed. This means it updates automatically without needing to reload your shell or run special commands.
