+## Why NixOS & Flakes?
 
-## TODO
+Nix allows for easy-to-manage, collaborative, reproducible deployments. This means that once something is setup and configured once, it works (almost) forever. If someone else shares their configuration, anyone can make use of it(if you really understand what you're copying/refering now).
 
-- vscode extensions - [nix-vscode-extensions](https://github.com/nix-community/nix-vscode-extensions)
+As for Flakes, refer to [Introduction to Flakes - NixOS & Nix Flakes Book](https://nixos-and-flakes.thiscute.world/nixos-with-flakes/introduction-to-flakes)
-- secret management - [sops-nix](https://github.com/Mic92/sops-nix)
-- switch from i3wm to hyprland
-  - i3wm: old and stable, only support X11
-  - sway: compatible with i3wm, support Wayland. do not support Nvidia GPU officially.
-  - [hyprland](https://wiki.hyprland.org/Nix/Hyprland-on-NixOS/): project starts from 2022, support Wayland, envolving fast, good looking, support Nvidia GPU.

-## How to install Nix and Deploy this Flake?
+Wallpapers: https://github.com/ryan4yin/wallpapers
 
-After installed NixOS with `nix-command` & `flake` enabled, you can deploy this flake with the following command:
+## Hyprland + AstroNvim
+
+![](./_img/hyprland_2023-07-29_1.webp)
+
+![](./_img/hyprland_2023-07-29_2.webp)

+
+## Neovim
+
+See [./home/base/desktop/neovim](./home/base/desktop/neovim) for details.
+
+## Hosts
+
+See [./hosts](./hosts) for details.
+
+## Secrets Management
+
+See [./secrets](./secrets) for details.
+
+## How to Deploy this Flake?
+
+> :red_circle: **IMPORTANT**: **You should NOT deploy this flake directly on your machine:exclamation: It will not succeed.** this flake contains my hardware configuration(such as [hardware-configuration.nix](hosts/idols/ai/hardware-configuration.nix), [cifs-mount.nix](https://github.com/ryan4yin/nix-config/blob/v0.1.1/hosts/idols/ai/cifs-mount.nix), [Nvidia Support](https://github.com/ryan4yin/nix-config/blob/v0.1.1/hosts/idols/ai/default.nix#L77-L91), etc.) which is not suitable for your hardware, and my private secrets repository [ryan4yin/nix-secrets](https://github.com/ryan4yin/nix-config/tree/main/secrets) that only I have access to. You may use this repo as a reference to build your own configuration.
+
+For NixOS:
+
+> To deploy this flake from NixOS's official ISO image(purest installation method), please refer to [./nixos-installer/](./nixos-installer/)
+
+> Need to restart the machine when switching between `wayland` and `xorg`.
 
 ```bash
-sudo nixos-rebuild switch .#nixos-test
+# deploy one of the configuration based on the hostname
+sudo nixos-rebuild switch --flake .#ai_i3
+# sudo nixos-rebuild switch --flake .#ai_hyprland
+
+# we can also deploy using `make`, which is defined in Makefile
+make i3    # deploy my pc with i3 window manager
+# make hypr  # deploy my pc with hyprland compositor
+
+# or we can deploy with details
+make i3-debug
+# make hypr-debug
 ```
 
+For macOS:
+
+```bash
+# deploy harmonicia's configuration(macOS Intel)
+make ha
+
+# deploy fern's configuration(Apple Silicon)
+make fe
+
+# deploy with details
+make ha-debug
+# make fe
+```
+
+> [What y'all will need when Nix drives you to drink.](https://www.youtube.com/watch?v=Eni9PPPPBpg) (copy from hlissner's dotfiles, it really matches my feelings when I first started using NixOS...)
+
+## How to create & managage VM from this flake?
+
+use `aquamarine` as an example, we can create a virtual machine with the following command:
+
+```shell
+# 1. generate a proxmox vma image file
+nom build .#aquamarine  # `nom`(nix-output-monitor) can be replaced by the standard command `nix`
+
+# 2. upload the genereated image to proxmox server's backup directory `/var/lib/vz/dump`
+#    please replace the vma file name with the one you generated in step 1.
+scp result/vzdump-qemu-aquamarine-nixos-23.11.20230603.dd49825.vma.zst root@192.168.5.174:/var/lib/vz/dump
+
+# 3. the image we uploaded will be listed in proxmox web ui's this page: [storage 'local'] -> [backups], we can restore a vm from it via the web ui now.
+```
+
+Once the virtual machine `aquamarine` is created, we can deploy updates to it with the following commands:
+
+```shell
+# 1. add the ssh key to ssh-agent
+ssh-add ~/.ssh/ai-idols
+
+# 2. deploy the configuration to all the remote host with tag `@dist-build`
+# using the ssh key we added in step 1
+colmena apply --on '@dist-build' --show-trace
+```
+
+If you're not familiar with remote deployment, please read this tutorial first: [Remote Deployment - NixOS & Flakes Book](https://nixos-and-flakes.thiscute.world/best-practices/remote-deployment)

+# AstroNvim Configuration and Shortcuts
+
+My Neovim config based on [AstroNvim](https://github.com/AstroNvim/AstroNvim).
+For more details, visit the [AstroNvim website](https://astronvim.com/).
+
+This document outlines neovim's configuration structure and various shortcuts/commands for efficient usage.
+
+## Configuration Structure
+
+| Description                                       | Standard Location                           | My Location                                                               |
+| ------------------------------------------------- | ------------------------------------------- | ------------------------------------------------------------------------- |
+| Neovim's config                                   | `~/.config/nvim`                            | AstroNvim's github repository, referenced as a flake input in this flake. |
+| AstroNvim's user configuration                    | `$XDG_CONFIG_HOME/astronvim/lua/user`       | [./astronvim_user/](./astronvim_user/)                                    |
+| Plugins installation directory (lazy.nvim)        | `~/.local/share/nvim/`                      | The same as standard location, generated and managed by lazy.nvim.        |
+| LSP servers, DAP servers, linters, and formatters | `~/.local/share/nvim/mason/`(by mason.nvim) | [./default.nix](./default.nix), installed by nix.                         |
+
+## Update/Clean Plugins
+
+Note that lazy.nvim will not automatically update plugins, so you need to update them manually.
+
+```bash
+:Lazy update
+```
+
+Remove all unused plugins:
+
+```bash
+:Lazy clean
+```

+
+## Text Manipulation
+
+- Add at the end of multiple lines: `:normal A<text>`
+
+  - Execublock: `:A<text>`
+
+  - visual block mode(ctrl + v)
+  - Append text at the end of each line in the selected block
+  - If position exceeds line end, neovim adds spaces automatically
+
+- Delete the last char of multivle lines: `:normal $x`
+
+  - Execute `$x` on each line
+  - visual mode(v)
+  - `$` moves cursor to the end of line
+  - `x` deletes the character under the cursor
+
+- Delete the last word of multiple lines: `:normal $bD`
+  - Execute `$bD` on each line
+  - visual mode(v)
+  - `$` moves cursor to the end of line
+  - `b` moves cursor to the beginning of the last word
+  - `D` deletes from cursor to the end of line

+
+
+## 'xterm-kitty': unknown terminal type when `ssh` into a remote host or `sudo xxx`
+
+> https://sw.kovidgoyal.net/kitty/faq/#i-get-errors-about-the-terminal-being-unknown-or-opening-the-terminal-failing-or-functional-keys-like-arrow-keys-don-t-work
+
+> https://wezfurlong.org/wezterm/config/lua/config/term.html
+
+kitty set `TERM` to `xterm-kitty` by default, and TUI apps like `viu`, `yazi`, `curses` will try to search in the host's [terminfo(terminal capability data base)](https://linux.die.net/man/5/terminfo) for value of `TERM` to determine the capabilities of the terminal.
+
+But when you `ssh` into a remote host, the remote host is very likely to not have `xterm-kitty` in its terminfo, so you will get this error:
+
+```
+'xterm-kitty': unknown terminal type
+```
+
+Or when you `sudo xxx`, `sudo` won't preserve the `TERM` variable, it will be reset to root's default `TERM` value, which is `xterm` or `xterm-256color` in most linux distributions, so you will get this error:
+
+```
+'xterm-256color': unknown terminal type
+```
+
+or 
+
+```
+Error opening terminal: xterm-kitty.
+```
+
+NixOS preserve the `TERMINFO` and `TERMINFO_DIRS` environment variables, for `root` and the `wheel` group: [nixpkgs/nixos/modules/config/terminfo.nix](https://github.com/NixOS/nixpkgs/blob/nixos-23.11/nixos/modules/config/terminfo.nix#L18)
+
+For nix-darwin, take a look at <https://github.com/LnL7/nix-darwin/wiki/Terminfo-issues>
+
+### Solutions
+
+Simplest solution, it will automatically copy over the terminfo files and also magically enable shell integration on the remote machine: 
+
+```
+kitten ssh user@host
+```
+
+Or if you do not care about kitty's features(such as true color & graphics protocol), you can simply set `TERM` to `xterm-256color`, which is built-in in most linux distributions:
+
+```
+export TERM=xterm-256color
+```
+
+If you need kitty's features, but do not like the magic of `kitten`, you can manually install kitty's terminfo on the remote host:
+
+```bash
+# install on ubuntu / debian
+sudo apt-get install kitty-terminfo
+
+# or copy from local machine
+infocmp -a xterm-kitty | ssh myserver tic -x -o \~/.terminfo /dev/stdin
+```

+## Proxy DNS requests - no leak for DNS data
+# (disable all of the 3 items below to not proxy your DNS requests)
+
+# method 1. this uses the proxychains4 style method to do remote dns:
+# a thread is spawned that serves DNS requests and hands down an ip
+# assigned from an internal list (via remote_dns_subnet).
+# this is the easiest (setup-wise) and fastest method, however on
+# systems with buggy libcs and very complex software like webbrowsers
+# this might not work and/or cause crashes.
+proxy_dns
+
+# method 2. use the old proxyresolv script to proxy DNS requests
+# in proxychains 3.1 style. requires `proxyresolv` in $PATH
+# plus a dynamically linked `dig` binary.
+# this is a lot slower than `proxy_dns`, doesn't support .onion URLs,
+# but might be more compatible with complex software like webbrowsers.
+#proxy_dns_old
+
+# method 3. use proxychains4-daemon process to serve remote DNS requests.
+# this is similar to the threaded `proxy_dns` method, however it requires
+# that proxychains4-daemon is already running on the specified address.
+# on the plus side it doesn't do malloc/threads so it should be quite
+# compatible with complex, async-unsafe software.
+# note that if you don't start proxychains4-daemon before using this,
+# the process will simply hang.
+#proxy_dns_daemon 127.0.0.1:1053
+
+# set the class A subnet number to use for the internal remote DNS mapping
+# we use the reserved 224.x.x.x range by default,
+# if the proxified app does a DNS request, we will return an IP from that range.
+# on further accesses to this ip we will send the saved DNS name to the proxy.
+# in case some control-freak app checks the returned ip, and denies to 
+# connect, you can use another subnet, e.g. 10.x.x.x or 127.x.x.x.
+# of course you should make sure that the proxified app does not need
+# *real* access to this subnet. 
+# i.e. dont use the same subnet then in the localnet section
+#remote_dns_subnet 127 
+#remote_dns_subnet 10
+remote_dns_subnet 224
+
+# Some timeouts in milliseconds
+tcp_read_time_out 15000
+tcp_connect_time_out 8000
+
+### Examples for localnet exclusion
+## localnet ranges will *not* use a proxy to connect.
+## note that localnet works only when plain IP addresses are passed to the app,
+## the hostname resolves via /etc/hosts, or proxy_dns is disabled or proxy_dns_old used.
+
+## Exclude connections to 192.168.1.0/24 with port 80
+# localnet 192.168.1.0:80/255.255.255.0
+
+## Exclude connections to 192.168.100.0/24

+## Exclude connections to ANYwhere with port 80
+# localnet 0.0.0.0:80/0.0.0.0
+# localnet [::]:80/0
+
+## RFC6890 Loopback address range
+## if you enable this, you have to make sure remote_dns_subnet is not 127
+## you'll need to enable it if you want to use an application that 
+## connects to localhost.
+# localnet 127.0.0.0/255.0.0.0
+# localnet ::1/128
+
+## RFC1918 Private Address Ranges

+# localnet 192.168.0.0/255.255.0.0
+
+### Examples for dnat
+## Trying to proxy connections to destinations which are dnatted,
+## will result in proxying connections to the new given destinations.
+## Whenever I connect to 1.1.1.1 on port 1234 actually connect to 1.1.1.2 on port 443
+# dnat 1.1.1.1:1234  1.1.1.2:443
+
+## Whenever I connect to 1.1.1.1 on port 443 actually connect to 1.1.1.2 on port 443
+## (no need to write :443 again)
+# dnat 1.1.1.2:443  1.1.1.2
+
+## No matter what port I connect to on 1.1.1.1 port actually connect to 1.1.1.2 on port 443
+# dnat 1.1.1.1  1.1.1.2:443

+# Home Manager's Linux Submodules
+
+1. `base`: The base module that is suitable for any NixOS environment.
+2. `desktop`: Configuration for desktop environments, such as Hyprland, I3, etc.
+3. `fcitx5`: fcitx5's configuration(Chinese input method).
+4. `hyprland`: Hyprland's configuration.
+5. `i3`: i3's configuration.
+6. `server.nix`: Configuration which is suitable for both servers and desktops. It import only `base` as its submodule.
+    1. used by all my nixos servers.
+6. `desktop-hyprland.nix`: the entrypoint of hyprland's configuration, it import all the submodules above, except `i3`.
+    1. used by my hyprland desktop.
+7. `desktop-i3.nix`: the entrypoint of i3's configuration, it import all the submodules above, except `hyprland`.
+    1. used by my i3 desktop.
+
+
+## Why install I3/Hyprland in Home Manager instead of a NixOS Module?
+
+1. I3 & Hyprland's configuration file is located in `~/.config`, which can be easily managed by Home Manager.
+2. There're other user-specific systemd servcies, such gammastep, wallpaper-switcher, etc. which can be easily managed by Home Manager, but if we start i3/hyprland in NixOS Module, they may failed to start automatically. With i3/hyprland installed via home-manager, we can control their systemd service's dependent order, to avoid issues like this.
+3. By install as less as possible in NixOS Module, we can:
+    1. Make the NixOS system more secure and stable.
+    2. Make this flake more portable to other non-NixOS systems, as home-manager can be installed on any Linux system.
