-This repository is home to the nix code that builds my systems.
+> My configuration is becoming more and more complex, and **it will be difficult for beginners to
+> read**. If you are new to NixOS and want to know how I use NixOS, I would recommend you to take a
+> look at the [ryan4yin/nix-config/releases](https://github.com/ryan4yin/nix-config/releases) first,
+> **checkout to some simpler older versions, such as
+> [i3-kickstarter](https://github.com/ryan4yin/nix-config/tree/i3-kickstarter), which will be much
+> easier to understand**.
 
-## Why Nix?
+This repository is home to the nix code that builds my systems:
 
-Nix allows for easy-to-manage, collaborative, reproducible deployments. This means that once something is setup and configured once, it works forever. If someone else shares their configuration, anyone can make use of it.
+1. NixOS Desktops: NixOS with home-manager, i3, hyprland, agenix, etc.
+2. macOS Desktops: nix-darwin with home-manager, share the same home-manager configuration with
+   NixOS Desktops.
+3. NixOS Servers: virtual machines running on Proxmox/KubeVirt, with various services, such as
+   kubernetes, homepage, prometheus, grafana, etc.
 
-**Want to know Nix in detail? Looking for a beginner-friendly tutorial or best practices? Check out [NixOS & Nix Flakes Book - 🛠️ ❤️ An unofficial & opinionated :book: for beginners](https://github.com/ryan4yin/nixos-and-flakes-book)!**

+## Why NixOS & Flakes?
+
+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 else can just use it (if you really understand what you're copying/refering
+now).
+
+As for Flakes, refer to

 ## 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)) 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.
+> :red_circle: **IMPORTANT**: **You should NOT deploy this flake directly on your machine

+> [hardware-configuration.nix](hosts/idols-ai/hardware-configuration.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 hardwares, and requires my private secrets repository
+> [ryan4yin/nix-secrets](https://github.com/ryan4yin/nix-config/tree/main/secrets) to deploy. You
+> may use this repo as a reference to build your own configuration.
 
-After installing NixOS with `nix-command` & `flake` enabled, follow the steps below to deploy this flake.
+For NixOS:
 
-For NixOS, use the following commands:
+> 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
 # deploy one of the configuration based on the hostname
-sudo nixos-rebuild switch --flake .#ai_i3
+# sudo nixos-rebuild switch --flake .#ai_i3
-# sudo nixos-rebuild switch --flake .#ai_hyprland
+sudo nixos-rebuild switch --flake .#ai-hyprland
 
-# we can also deploy using `make`, which is defined in Makefile
+# deploy via `just`(a command runner with similar syntax to make) & Justfile
-make i3    # deploy my pc with i3 window manager
+# just i3    # deploy my pc with i3 window manager
-# make hypr  # deploy my pc with hyprland compositor
+just hypr  # deploy my pc with hyprland compositor
 
 # or we can deploy with details
-make i3-debug
+# just i3 debug
-# make hypr-debug
+just hypr debug
 ```
 
-For MacOS, use the following commands:
+For macOS:
 
 ```bash
-# deploy the darwin configuration(harmonicia)
+# If you are deploying for the first time,
-make ha
+# 1. install nix & homebrew manually.
+# 2. prepare the deployment environment with essential packages available
+nix-shell -p just nushell
+# 3. comment home-manager's code in lib/macosSystem.nix to speed up the first deplyment.
+# 4. comment out the proxy settings in scripts/darwin_set_proxy.py if the proxy is not ready yet.
+
+# 4. deploy harmonica's configuration(macOS Intel)
+just ha
+
+# deploy fern's configuration(Apple Silicon)
+just fe
 
 # deploy with details
-make ha-debug
+just ha debug
+# just fe debug
 ```
 
-## Install Apps from Flatpak
+> [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...)
-We can install apps from flathub, which has a lot of apps that are not supported well in nixpkgs.
-
-```bash
-# Add the Flathub repository
-flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
-
-# install apps from flathub
-flatpak install netease-cloud-music-gtk
-
-# install 3d printer slicer - cura
-flatpak install flathub com.ultimaker.cura
-
-# or you can search apps from flathub
-flatpak search <keyword>
-# search on website is also supported: https://flathub.org/
-```
-
-## 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 the remote host, using the ssh key we added in step 1
-#    and the username defaults to `$USER`, it's `ryan` in my case.
-nixos-rebuild --flake .#aquamarine --target-host aquamarine --build-host aquamarine switch --use-remote-sudo --verbose
-
-# or we can replace the command above with the following command, which is defined in Makefile
-make aqua
-```
-
-The commands above will build & deploy the configuration to `aquamarine`, the build process will be executed on `aquamarine` too, and the `--use-remote-sudo` option indicates that we will use `sudo` on the remote host.

+## How to create & managage KubeVirt's Virtual Machine from this flake?
+
+Use `aquamarine` as an example, we can create a virtual machine with the following command:
+
+```shell
+just upload-vm aquamarine
+```
+
+Then create the virtual machine by creating a yaml file at
+[ryan4yin/k8s-gitops](https://github.com/ryan4yin/k8s-gitops/tree/main/vms)
+
+Once the virtual machine `aquamarine` is created, we can deploy updates to it with the following
+commands:
+
+```shell
+just col aquamarine
+just col kubevirt-shoryu
+just col k3s-test-1-master-1
+```
+
+If you're not familiar with remote deployment, please read this tutorial first:

+# Terminal Emulators
+
+I used to spend a lot of time on terminal emulators, to make them match my taste, but now I found
+that it's not worth it, **Zellij can provide a user-friendly and unified user experience for all
+terminal emulators! without any pain**!
+
+Currently, I only use the most basic features of terminal emulators, such as true color, graphics
+protocol, etc. Other features such as tabs, scrollback buffer, select/search/copy, etc, are all
+provided by zellij!
+
+My current terminal emulators are:
+
+1. kitty: My main terminal emulator.
+   1. to select/copy a large mount of text, We should do some tricks via kitty's `scrollback_pager`
+      with neovim, it's really painful: <https://github.com/kovidgoyal/kitty/issues/719>
+2. wezterm: My secondary terminal emulator.
+   1. its search ability is very basic, and it's not easy to use.
+   1. its scrollback buffer's copy mode is very like vim, which is nice, but zellij's even better,
+      it can use neovim as its default scrollback buffer's editor without any pain!
+3. foot: a fast, lightweight and minimalistic Wayland terminal emulator.
+   1. foot only do the things a terminal emulator should do, no more, no less.
+   1. It's really suitable for tiling window manager or zellij users!
+
+## '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-24.05/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
+```

+### LSP - Language Server Protocol
+
+> https://en.wikipedia.org/wiki/Language_Server_Protocol
+
+> https://langserver.org/
+
+The Language Server Protocol (LSP) is an open, JSON-RPC-based protocol for use between source code
+editors or integrated development environments (IDEs) and servers that provide programming
+language-specific features like:
+
+- motions such as go-to-definition, find-references, hover.
+- **code completion**
+- **marking of warnings and errors**
+- **refactoring routines**
+- syntax highlighting (use Tree-sitter instead)
+- code formatting (use a dedicated formatter instead)
+
+The goal of the protocol is to allow programming language support to be implemented and distributed
+independently of any given editor or IDE.
+
+LSP was originally developed for Microsoft Visual Studio Code and is now an open standard. In the
+early 2020s LSP quickly became a "norm" for language intelligence tools providers.
+
+### Tree-sitter
+
+> https://tree-sitter.github.io/tree-sitter/
+
+> https://www.reddit.com/r/neovim/comments/1109wgr/treesitter_vs_lsp_differences_ans_overlap/
+
+Tree-sitter is a parser generator tool and an **incremental parsing** library. It can build a
+concrete syntax tree for a source file and efficiently update the syntax tree as the source file is
+edited.
+
+It is used by many editors and IDEs to provide:
+
+- **syntax highlighting**
+- **indentation**
+- **creating foldable code regions**
+- **Incremental selection**
+- **simple refactoring in a single file**
+  - such as join/split lines, structural editing, cursor motion, etc.
+
+**Treesitter process each file independently**, and it is not aware of the semantics of your code.
+For example, it does not know does a function/variable really exist, or what is the type/return-type
+of a variable. This is where LSP comes in.
+
+The LSP server parses the code much more deeply and it **not only parses a single file but your
+whole project**. So, the LSP server will know whether a function/variable does exist with the same
+type/return-type. If it does not, it will mark it as an error.
+
+**LSP does understand the code semantically, while Treesitter only cares about correct syntax**.
+
+#### LSP vs Tree-sitter
+
+- Tree-sitter: lightweight, fast, but limited knowledge of your code. mainly used for **syntax
+  highlighting, indentation, and folding/refactoring in a single file**.
+- LSP: heavy and slow on large projects, but it has a deep understanding of your code. mainly used
+  for **code completion, refactoring in the projects, errors/warnings, and other semantic-aware
+  features**.
+
+### Formatter vs Linter
+
+Linting is distinct from Formatting because:
+
+1. **formatting** only restructures how code appears.
+   1. `prettier` is a popular formatter.
+1. **linting** analyzes how the code runs and detects errors, it may also suggest improvements such
+   as replace `var` with `let` or `const`.
+
+Formatters and Linters process each file independently, they do not need to know about other files
+in the project.

+# Editors
+
+My editors:
+
+1. Neovim
+2. Emacs
+3. Helix
+
+And `Zellij` for a smooth and stable terminal experience.
+
+## Tips
+
+1. Many useful keys are already provided by vim, check vim/neovim's docs before you install a new
+   plugin / reinvent the wheel.
+1. After using Emacs/Neovim more skillfully, I strongly recommend that you read the official
+   documentation of Neovim/vim:
+   1. <https://vimhelp.org/>: The official vim documentation.
+   1. <https://neovim.io/doc/user/>: Neovim's official user documentation.
+1. Use Zellij for terminal related operations, and use Neovim/Helix for editing.
+1. As for Emacs, Use its GUI version & terminal emulator `vterm` for terminal related operations.
+1. Two powerful file search & jump tools:
+1. Tree-view plugins are beginner-friendly and intuitive, but they're not very efficient.
+1. **Search by the file path**: Useful when you're familiar with the project structure, especially
+   on a large project.
+1. **Search by the content**: Useful when you're familiar with the code.
+
+## Tutorial
+
+Type `:tutor`(`:Tutor` in Neovim) to learn the basics usage of vim/neovim.
+
+## VIM's Cheetsheet
+
+> Here only record my commonly used keys, to see **a more comprehensive cheetsheet**:
+> <https://vimhelp.org/quickref.txt.html>
+
+Both Emacs-Evil & Neovim are compatible with vim, sothe key-bindings described here are common in
+both Emacs-Evil, Neovim & vim.
+
+### Terminal Related
+
+I mainly use Zellij for terminal related operations, here is its terminal shortcuts I use frequently
+now:
+
+| Action                    | Zellij's Shortcut |
+| ------------------------- | ----------------- |
+| Floating Terminal         | `Ctrl + p + w`    |
+| Horizontal Split Terminal | `Ctrl + p + d`    |
+| Vertical Split Terminal   | `Ctrl + p + n`    |
+| Execute a command         | `!xxx`            |

+### Motion
+
+> https://vimhelp.org/motion.txt.html
+
+| Action                                              | Command                                            |
+| --------------------------------------------------- | -------------------------------------------------- |
+| Move to the start/end of the buffer                 | `gg`/`G`                                           |
+| Move the line number 5                              | `5gg` / `5G`                                       |

+| Jump to various positions                           | `'` + some other keys(neovim has prompt)           |
+
+Text Objects:
+
+- **sentence**: text ending at a '.', '!' or '?' followed by either the end of a line, or by a space
+  or tab.
+- **paragraph**: text ending at a blank line.
+- **section**: text starting with a section header and ending at the start of the next section
+  header (or at the end of the file). - The "`]]`" and "`[[`" commands stop at the '`{`' in the
+  first column. This is useful to find the start of a function in a C/Go/Java/... program.
+
+### Text Manipulation
+
+Basics:
+
+| Action                                  |                            |

+  - 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
+
+### Search
+
+| Action                                                | Command   |
+| ----------------------------------------------------- | --------- |
+| Search forward/backword for a pattern                 | `/` / `?` |
+| Repeat the last search in the same/opposite direction | `n` / `N` |
+
+### Find and Replace
+
+| Action                           | Command                             |
+| -------------------------------- | ----------------------------------- |
+| Replace in selected area         | `:s/old/new/g`                      |
+| Replace in current line          | Same as above                       |
+| Replace all the lines            | `:% s/old/new/g`                    |
+| Replace all the lines with regex | `:% s@\vhttp://(\w+)@https://\1@gc` |
+
+1. `\v` means means that in the regex pattern after it can be used without backslash
+   escaping(similar to python's raw string).
+2. `\1` means the first matched group in the pattern.
+
+### Replace in the specific lines
+
+| Action                                    | Command                                |

+| Remove the trailing spaces                | `:% s/\s\+$//g`                        |
+
+The postfix(flags) in the above commands:
+
+1. `g` means replace all the matched strings in the current line/file.
+2. `c` means ask for confirmation before replacing.
+3. `i` means ignore case.
+

+## Install or Update
+
+After deploying this nix flake, run the following command to install or update emacs:
+

+doom sync
+```
+
+when in doubt, run `doom sync`!
+
+## Testing
+
+> via `Justfile` located at the root of this repo.

+
+# clear test data
+just emacs-clean
+```
+
+## Limits
+
+- It's too slow to start up and install(compile/build) packages.
+  - I have to use emacs in daemon/client mode to avoid this issue.
+- It's too large in size, not suitable for servers.
+  - So vim/neovim is still the best choice for servers.
+- Emacs's markdown-mode works not well with tables, see:
+  - https://github.com/jrblevin/markdown-mode/issues/380
+- I use git command frequently, but doomemacs only autoupdates status of git diff / treemacs when
+  using magit.
+  - I have to learn magit to avoid this issue...
+- GitHub's orgmode support is not well, Markdown is better for GitHub.
+  - Use markdown for repo's README.md, and use orgmode for my personal notes and docs only.
+
+## Cheetsheet
+
+Here is the cheetsheet related to my DoomEmacs configs. Please read vim's common cheetsheet at
+[../README.md](../README.md) before reading the following.
+
+### Basics
+
+> Terminal(vterm) is useful in GUI mode, I use Zellij instead in terminal mode.
+
+| Action                 | Shortcut                                          |

+1. `foo`: the keyword to search
+1. `C-; E`: exports what you’re looking at into a new buffer in grep-mode
+1. `C-c C-p` to run wgrep-change-to-wgrep-mode to make the search results writable.
+1. `:%s/foo/bar/g RET`: replace in the current buffer(just like neovim/vim)
+1. `Z Z`: to write all the changes to their respective files

+# Helix Editor
+
+Neovim is really powerful, and have a very active community. I use it as my main editor, and I'm
+very happy with it. I use it for everything, from writing code to writing this document.
+
+But its configuration is a bit complex, and finding the right plugins, writing configurations, and
+keeping everything up to date is not easy.
+
+That's why I'm interested in Helix, Helix is similar to Neovim, but it's more opinionated, and it's
+batteries included. Whether I'll switch my main editor to Helix or not, it gives me a lot of ideas
+on how to improve my Neovim workflow.
+
+## Tutorial
+
+Use `:tutor` in helix to start the tutorial.
+
+## Differences between Neovim and Helixer
+
+1. Selecting first, then action.
+   1. Helix: delete 2 word: `2w` then `x`. You can always see what you're selecting before you apply
+      the action.
+   2. Neovim: delete 2 word: `d`. then `2w`. No visual feedback before you apply the action.
+1. Helix - Morden builtin features: LSP, tree-sitter, fuzzy finder, multi cursors, surround and
+   more.
+   1. They're all available in Neovim too, but you need to find and use the right plugins manually,
+      which takes time and effort.
+1. Helix is built in Rust from scratch. The result is a much smaller codebase and a modern set of
+   defaults. No VimScript. No Lua.
+   1. Neovim contains a lot of VimScript, and lua is too dynamic, it's hard to debug.
+   1. Personally I'm glad to take a look at a Rust codebase, but not a VimScript/Lua codebase.
+1. Neovim have a very activate plugin ecosystem, and it's easy to find plugins for almost
+   everything.
+   1. Helix is still new, and it even don't have a stable plugin system yet. A PR to add a plugin
+      system is still envolving: <https://github.com/helix-editor/helix/pull/8675>
+1. Neovim has integrated terminal, and it's very powerful. It's quite similar to VSCode's integrated
+   terminal. I use it a lot.
+   1. Helix doesn't have a integrated terminal yet, as it's complicated to implement. Users are
+      recommended to use tmux/Zellij or Wezterm/Kitty to implement this feature instead.
+   1. <https://github.com/helix-editor/helix/issues/1976#issuecomment-1091074719>
+   1. <https://github.com/helix-editor/helix/pull/4649>
+   1. **My Neovim often gets stuck when I switch to
+      [toggleterm.nvim](https://github.com/akinsho/toggleterm.nvim), this Helix issue made me
+      consider to switch from this Neovim plugin to Zellij**.
+1. Helix do not have a tree-view panel, it's recommended to use Yazi/ranger/Broot instead, and open
+   Helix in them.
+   1. a tree-view plugin may be added after the plugin system is stable, but no one knows when it
+      will be.
+   2. and some Helix users stated that they don't need a tree-view plugin, Helix's file picker is
+      useful and good enough.
+1. It seems Helix lacks a global substitution command, you should run it in another window(via wm or
+   Zellij).
+   1. <https://github.com/helix-editor/helix/issues/196>
+   1. Neovim's substitution command allow you to preview the changes before you apply it, and it's
+      very useful. if I switch to Helix, I'll need to find some other tools with similar
+      feature(such as https://github.com/ms-jpq/sad).
+1. Complexity and Maintenance Costs vs Batteries Included:
+   <https://github.com/helix-editor/helix/discussions/6356>
+
+I think Use Helix/Neovim within a terminal file manager(Yazi/ranger/Broot) and Zellij is a good
+idea. It's quite different from the workflow I migrated from VSCode/JetBrains before, I'm very
+interested in it.
+
+In Neovim I can make the workflow similar to VSCode/JetBrains by using some plugins, but Helix
+forces me to get out of my comfort zone, and try something new.

+# Neovim Editor
+
+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.
+
+## Screenshots

+
+## 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
+```
+
+## Testing
+
+> via `Justfile` located at the root of this repo.
+
+```bash
+# testing
+just nvim-test
+
+# clear test data
+just nvim-clear
+```
+
