-## Why Nix?

-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.
+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).

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_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
+# deploy via `just`(a command runner with similar syntax to make) & Justfile
+just i3    # deploy my pc with i3 window manager
+# just hypr  # deploy my pc with hyprland compositor
 
 # or we can deploy with details
-make i3-debug
-# make hypr-debug
+just i3 debug
+# just hypr-debug
 ```
 
-For MacOS, use the following commands:
+For macOS:
 
 ```bash
-# deploy the darwin configuration(harmonicia)
-make ha
+# deploy harmonicia'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
-
-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/
-```

+### 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:
+
+- **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.
+
+## Tutorial
+
+Type `:tutor`(`:Tutor` in Neovim) to learn the basics usage of vim/neovim.
+
+## VIM's Cheetsheet
+
+> Here only record my commonly used keyboard keys, to see **a more comprehensive cheetsheet**: <https://github.com/rtorr/vim-cheat-sheet>
+
+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:

+
+### 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 whole file    | `:% s/old/new/g`                    |
+| Replace 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.

+
+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.
+
+### Buffers, Windows and Tabs
+
+- A buffer is the in-memory text of a file.
+- A window is a viewport on a buffer.
+- A tab page is a collection of windows.
+
+| Action                              | Command                             |

+1. Explore the unknown, just for fun!
+2. Org Mode
+3. Lisp Coding
+
+## Install or Update
+
+After deploying this nix flake, run the following command to install or update emacs:
+
+```bash
+doom sync
+```
+
+when in doubt, run `doom sync`!
+
+## Testing

+## 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.
+
+> We can run any emacs command via `M-x`(Alt + x).
+
+| Action                 | Shortcut      |
+| ---------------------- | ------------- |
+| Popup Terminal(vterm)  | `SPC + o + t` |
+| Open Terminal          | `SPC + o + T` |
+| Open file tree sidebar | `SPC + o + p` |

+
+### Window Navigation
+
+| Action                                     | Shortcut                                                              |
+| ------------------------------------------ | --------------------------------------------------------------------- |
+| Split a window vertically and horizontally | `SPC w v/s`                                                           |
+| Move to a window in a specific direction   | `Ctrl-w + h/j/k/l`                                                    |

+### Image Preview(GUI mode only)
+
+Use `-`, `+` to resize the image, `r` to rotate the image.
+
+### Search & replace
+
+```bash
+SPC s p foo C-; E C-c C-p :%s/foo/bar/g RET Z Z
+```
+
+1. `SPC s p`: search in project
+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
+
+### Projects
+
+> easily switch between projects without exit emacs!
+
+| Action                     |               |
+| -------------------------- | ------------- |
+| Switch between projects    | `SPC + p + p` |
+| Browse the current project | `SPC + p + .` |
+| Add new project            | `SPC + p + a` |
+
+### Workspaces
+
+> Very useful when run emacs in daemon/client modes
+
+| Action                      |                             |
+| --------------------------- | --------------------------- |
+| Switch between workspaces   | `M-1/2/3/...`(Alt-1/2/3/..) |
+| New Workspace               | `SPC + TAB + n`             |
+| New Named Workspace         | `SPC + TAB + N`             |
+| Delete Workspace            | `SPC + TAB + d`             |

+# 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.
+
+## Differences between Neovim and Helixer
+
+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 do have a stable plugin system yet. A PR to add a plugin system is still envolving: <https://github.com/helix-editor/helix/pull/8675>
+2. Neovim has intergrated terminal, and it's very powerful. It's quite similar to VSCode's intergrated terminal. I use it a lot.
+    1. Helix doesn't have a intergrated 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 substitution command, you should run it in another window(via wm or Zellij).
+    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).
+    2. The downside of Neovim's substitution command is that it's unable to save the command we just typed. If I made some things wrong, I have to type the whole substitution command again.
+
+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.

+## 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
+```
+

+# Termianl 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-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
+```

+# Zellij - A workspace lives in your terminal
+
+Zellij is a terminal workspace with batteries included.
+At its core, it is a terminal multiplexer (similar to tmux and screen), but this is merely its infrastructure layer.
+
+Zellij is very user-friendly and easy to use, with a step-by-step hint system that will help you get to know the keybindings, which is very like the Neovim or helix.
+
+> By contrast, tmux's key design is counterintuitive, there is no prompt system, and the plug-in performance is rubbish. It's really a pain to use.
+> tmux's inital release was in 2007, it's too old, I would recommend any users that do not have a experience with multiplexer to use zellij instead of tmux.
+
+## Why use zellij as the detault terminal environment?
+
+By auto start zellij on shell login, and exit the shell session on zellij exit, we can use zellij as the default terminal environment.
+
+By this way, We will only use the most basic features of the terminal emulator(kitty/alacritty/wezterm/...),
+while most of the functions of terminal are provided by zellij.
+Thus we can easily switch to any terminal emulator without losing any key functions,
+and do not need to take care of the differences between different terminal emulators.
+
+And Zellij can be used not only locally, but also on any remote server, which is very convenient. Learn once and use everywhere!
+
+> Yeah, you didn't misread it, zellij is very suitable for not only remotely, but also locally!
+
+Some features such as search/copy/scrollback in different terminal emulators are implemented in different ways, and has different user experience.
+For example, Wezterm's default search function is very basic, and it's not easy to use. Kitty's scrollback search/copy is really tricky to use.
+As for some Editor such as Neovim, its intergrated terminal is really useful, but zellij is more powerful and useful than it, and more stable!
+Zellij overcomes these problems, and provides a unified user experience for all terminal emulators!
+
+Teminal emulators should only be responsible for displaying characters.
+
+## Passthrough mode(Lock Mode)
+
+`Ctrl + g` lock the outer zellij interface, and all keys will be sent to the focused pane.
+
+It's extremely useful when you want to:
+
+1. Use zellij locally for daily work, and use a remote zellij via ssh to do some work on the remote server.
+1. To avoid the key conflicts between zellij and the program running in the terminal, such as vim, tmux, etc.

+## Proxy DNS requests - no leak for DNS data

+
+# 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.

+# Some timeouts in milliseconds

+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.

+3. `base`: all common configurations for all desktops.
+4. `hyprland`: Hyprland's configuration.
+5. `i3`: i3's configuration.
+
+
+## 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.
