# Nixified dotfiles
## Initial setup on NixOS
1. Setup NixOS using the installer.
1. Once installed, edit `/etc/nixos/configuration.nix` and rebuild:
* Enable sshd
* Change hostname
* Enable flakes: `nix.settings.experimental-features = [ "flakes" ];`
1. SSH to the machine.
1. Clone this repo recursively (need to setup ssh keys, use a nix-shell with git and neovim).
1. Setup a GitHub personal access token in `~/.config/nix/nix.conf` (see [doc](https://nix.dev/manual/nix/2.18/command-ref/conf-file#conf-access-tokens))
```conf
access-tokens = github.com:
```
1. Setup home-manager & activate it.
1. Copy `/etc/nixos/*.nix` to this repo to compare & adapt.
1. Rebuild nixos & switch using this flake.
1. Enable vscode server patcher (see )
1. Enable service: `systemctl --user enable --now auto-fix-vscode-server.service` (it's safe to ignore warning)
1. To prevent GC: `ln -sfT /run/current-system/etc/systemd/user/auto-fix-vscode-server.service ~/.config/systemd/user/auto-fix-vscode-server.service`
## Initial setup on MacOS
1. Download nix installer & run it with multi-user mode enabled: `curl -L https://nixos.org/nix/install | sh -s -- --daemon`
1. Enable flakes: `mkdir -p ~/.config/nix/ && echo 'experimental-features = nix-command flakes fetch-closure' > ~/.config/nix/nix.conf`
1. Clone this repo recursively.
1. Setup home-manager & activate it.
1. Install [HomeBrew](https://brew.sh/).
1. Setup nix-darwin & activate it.
## Initial setup on Non-NixOS Linux
1. Download nix installer & run it with multi-user mode enabled: `curl -L https://nixos.org/nix/install | sh -s -- --daemon`
1. Enable flakes: `mkdir -p ~/.config/nix/ && echo 'experimental-features = nix-command flakes fetch-closure' > ~/.config/nix/nix.conf`
1. On Linux, configure nix by adding to `/etc/nix/nix.conf`.
No need to do it on Darwin since we already do it nix-darwin (see [configuration.nix](./darwin/mbpapp/configuration.nix))
```conf
keep-outputs = true
keep-derivations = true
auto-optimise-store = true
# allow use of cached builds, require fast internet
builders-use-substitutes = true
experimental-features = nix-command flakes fetch-closure
```
1. Build `./x home build` and activate `./x home switch`
1. Activate shell by adding `/home/appaquet/.nix-profile/bin/fish` to `/etc/shells`
and running `chsh -s /home/appaquet/.nix-profile/bin/fish`
## Initial setup for Raspberry Pi
### Notes
* is used to simplify a lot of the quirks for Rpi.
* Because of the use of `raspberry-pi-nix`, there is no need for a `hardware-configuration.nix` as it's automatically generated & included.
* I use a Mac VM to build the initial SD card to prevent potentially recompiling the whole kernel on a poor Rpi.
### Steps
1. On a UTM NixOS host, create the Rpi NixOS config, and then build and SD card: `nix build '.#nixosConfigurations.piapp.config.system.build.sdImage'`
1. Copy the result image to a SD / USB Stick or Nvme (via USB adapter): `zstdcat result/the-image.img.zstd | dd of=/dev/the-device status=progress`
1. Boot the Rpi and change password.
1. Follow normal procedure to setup home-manager & rebuild NixOS.
## Common
1. The [nix-community](https://app.cachix.org/cache/nix-community) cachix cache may need to be configured and enabled manually before building nixos for the
first time (`cachix use nix-community`).
## Troubleshooting
1. It seems that when switching to newer fish, the paths weren't properly set.
On top of that, it may be shadowed by a global fish path too.
Reset fish paths with:
```bash
set -ge fish_user_paths
set -Ua fish_user_paths /nix/var/nix/profiles/default/bin
set -Ua fish_user_paths /home/appaquet/.nix-profile/bin
set -Ua fish_user_paths /home/appaquet/.local/utils/
```
1. `failed: unable to open database file at ... command-not-found`
As root, run:
```
nix-channel --add https://nixos.org/channels/nixos-unstable nixos
nix-channel --update
```
1. On MacOS, we may end up with an older version of nix installed, leading to flakes
not working because of use of newer syntax in the lock files (see )
The fix is to uninstall the old one: `sudo -i nix-env --uninstall nix`
## Cheat sheets
## Nix
* Run a uninstalled package: `nix run nixpkgs#cowsay hello world`
* Run a uninstalled package, with fuzzy finding: `nix run nixpkgs#(fzf-nix)`, or `nr`
* Start a shell with a package: `nix shell nixpkgs#ripgrep`
* Start a shell with a package, with fuzzy finding: `nix shell nixpkgs#(fzf-nix)`, or `ns`
### Fish
* Foreign env is used to source `~/.profile`. Any local variables can be set there.
* Paths: fish uses `fish_user_paths` to define paths and can be persisted when using "universal variables" (set with `-U`).
* To add a path: `fish_add_path /some/new/path` or `set -Ua fish_user_paths /some/new/path`
* To list current paths: `echo $fish_user_paths | tr " " "\n" | nl`
* To remove a path: `set --erase fish_user_paths[NUMBER AS LISTED STARTING AT 1]`
* Shortcuts
