-## TODO
-
-- enable disk encryption to enhance data security
-- make fcitx5-rime work in vscode/chrome/telegram on wayland
-- auto unlock with `ssh-agent` after login
-  - [People using ssh-agent, how do you unlock it on login? - reddit](https://www.reddit.com/r/NixOS/comments/lsbo9a/people_using_sshagent_how_do_you_unlock_it_on/)
-- update scripts for i3wm, especially rofi & screenshot
-- fix `xdg-open`: after set `firefox.desktop` as defaultApplication, NixOS returned error `no apps installed that can open "https://baidu.com"`
-- `Xcursor.size` do not take effect in i3

 ## 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.

 ## How to Deploy this Flake?
 
-> Note: you should NOT deploy this flake directly on your machine, it contains my hardware information and personal information which is not suitable for you. 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: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.
 
-After installed NixOS with `nix-command` & `flake` enabled, flow the steps below to deploy this flake.
+For MacOS:
-
-For NixOS, use the following commands:
-
-```bash
-# deploy my test configuration
-sudo nixos-rebuild switch --flake .#nixos-test
-
-
-# deploy my PC's configuration
-sudo nixos-rebuild switch --flake .#msi-rtx4090
-
-# or just deploy with hostname
-sudo nixos-rebuild switch
-
-# we can also deploy using make, which is defined in Makefile
-make deploy
-```
-
-For MacOS, use the following commands:
 
 ```bash
 # deploy the darwin configuration(harmonicia)
-make darwin
+make ha
 
 # deploy with details
-make darwin-debug
+make ha-debug
 ```
 
-## Install Apps from Flatpak
+For NixOS:
 
-We can install apps from flathub, which has a lot of apps that are not supported well in nixpkgs.
+> Need to restart the machine when switching between `wayland` and `xorg`.
 
 ```bash
-# Add the Flathub repository
+# deploy one of the configuration based on the hostname
-flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
+sudo nixos-rebuild switch --flake .#ai_i3
+# sudo nixos-rebuild switch --flake .#ai_hyprland
 
-# install apps from flathub
+# we can also deploy using `make`, which is defined in Makefile
-flatpak install netease-cloud-music-gtk
+make i3    # deploy my pc with i3 window manager
+# make hypr  # deploy my pc with hyprland compositor
 
-# install 3d printer slicer - cura
+# or we can deploy with details
-flatpak install flathub com.ultimaker.cura
+make i3-debug
-
+# make hypr-debug
-# or you can search apps from flathub
-flatpak search <keyword>
-# search on website is also supported: https://flathub.org/
 ```
 
-## Other Interesting Dotfiles

+## How to create & managage VM from this flake?
 
-- [notwidow/hyprland](https://github.com/notwidow/hyprland): hyprland configuration
+use `aquamarine` as an example, we can create a virtual machine with the following command:
-- [denisse-dev/dotfiles](https://github.com/denisse-dev/dotfiles)
+
-- [notusknot/dotfiles-nix](https://github.com/notusknot/dotfiles-nix)
+```shell
-- [xddxdd/nixos-config](https://github.com/xddxdd/nixos-config)
+# 1. generate a proxmox vma image file
-- [bobbbay/dotfiles](https://github.com/bobbbay/dotfiles)
+nom build .#aquamarine  # `nom`(nix-output-monitor) can be replaced by the standard command `nix`
-- [gytis-ivaskevicius/nixfiles](https://github.com/gytis-ivaskevicius/nixfiles)
+
-- [fufexan/dotfiles](https://github.com/fufexan/dotfiles)
+# 2. upload the genereated image to proxmox server's backup directory `/var/lib/vz/dump`
-- [davidtwco/veritas](https://github.com/davidtwco/veritas)
+#    please replace the vma file name with the one you generated in step 1.
-- [NixOS-CN/NixOS-CN-telegram](https://github.com/NixOS-CN/NixOS-CN-telegram)
+scp result/vzdump-qemu-aquamarine-nixos-23.11.20230603.dd49825.vma.zst root@192.168.5.174:/var/lib/vz/dump
-- [Tips&Tricks for NixOS Desktop](https://discourse.nixos.org/t/tips-tricks-for-nixos-desktop/28488/2)
+
+# 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
+```

+# 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
+```
+

+
+## Search and Jump
+
+Provided by [flash.nvim](https://github.com/folke/flash.nvim), it's a intelligent search and jump plugin.
+
+1. It enhaces the default search and jump behavior of neovim.(search with prefix `/`)
+
+| Action            | Shortcut                                                                                                      |
+| ----------------- | ------------------------------------------------------------------------------------------------------------- |
+| Search            | `/`(normal search), `s`(disable all code highlight, only highlight matches)                                   |
+| Treesitter Search | `yR`,`dR`, `cR`, `vR`, `ctrl+v+R`(arround your matches, all the surrounding Treesitter nodes will be labeled) |
+| Remote Flash      | `yr`, `dr`, `cr`, (arround your matches, all the surrounding Treesitter nodes will be labeled)                |
+
+## 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

+# Termianl Emulators
+
+1. kitty: My main terminal emulator.
+2. wezterm: My secondary terminal emulator.
+3. alacritty: Standby terminal.
+
+
+## '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
+```

-
-# List with all available hints
-#
-# Each hint must have any of `regex` or `hyperlinks` field and either an
-# `action` or a `command` field. The fields `mouse`, `binding` and
-# `post_processing` are optional.
-#
-# The `hyperlinks` option will cause OSC 8 escape sequence hyperlinks to be
-# highlighted.
-#
-# The fields `command`, `binding.key`, `binding.mods`, `binding.mode` and
-# `mouse.mods` accept the same values as they do in the `key_bindings` section.
-#
-# The `mouse.enabled` field controls if the hint should be underlined while
-# the mouse with all `mouse.mods` keys held or the vi mode cursor is above it.
-#
-# If the `post_processing` field is set to `true`, heuristics will be used to
-# shorten the match if there are characters likely not to be part of the hint
-# (e.g. a trailing `.`). This is most useful for URIs and applies only to
-# `regex` matches.
-#
-# Values for `action`:
-#   - Copy
-#       Copy the hint's text to the clipboard.
-#   - Paste
-#       Paste the hint's text to the terminal or search.

-# Mouse bindings
-#
-# Mouse bindings are specified as a list of objects, much like the key
-# bindings further below.
-#
-# To trigger mouse bindings when an application running within Alacritty
-# captures the mouse, the `Shift` modifier is automatically added as a
-# requirement.
-#
-# Each mouse binding will specify a:
-#
-# - `mouse`:
-#
-#   - Middle
-#   - Left
-#   - Right
-#   - Numeric identifier such as `5`
-#
-# - `action` (see key bindings for actions not exclusive to mouse mode)
-#
-# - Mouse exclusive actions:
-#
-#   - ExpandSelection
-#       Expand the selection to the current mouse cursor location.
-#
-# And optionally:
-#
-# - `mods` (see key bindings)
-#mouse_bindings:
-#  - { mouse: Right,                 action: ExpandSelection }
-#  - { mouse: Right,  mods: Control, action: ExpandSelection }
-#  - { mouse: Middle, mode: ~Vi,     action: PasteSelection  }
-
-# Key bindings
-#
-# Key bindings are specified as a list of objects. For example, this is the
-# default paste binding:
-#
-# `- { key: V, mods: Control|Shift, action: Paste }`
-#
-# Each key binding will specify a:
-#
-# - `key`: Identifier of the key pressed
-#
-#    - A-Z
-#    - F1-F24
-#    - Key0-Key9
-#
-#    A full list with available key codes can be found here:
-#    https://docs.rs/winit/*/winit/event/enum.VirtualKeyCode.html#variants
-#
-#    Instead of using the name of the keys, the `key` field also supports using
-#    the scancode of the desired key. Scancodes have to be specified as a
-#    decimal number. This command will allow you to display the hex scancodes
-#    for certain keys:
-#
-#       `showkey --scancodes`.
-#
-# Then exactly one of:
-#
-# - `chars`: Send a byte sequence to the running application
-#
-#    The `chars` field writes the specified string to the terminal. This makes
-#    it possible to pass escape sequences. To find escape codes for bindings
-#    like `PageUp` (`"\x1b[5~"`), you can run the command `showkey -a` outside
-#    of tmux. Note that applications use terminfo to map escape sequences back
-#    to keys. It is therefore required to update the terminfo when changing an
-#    escape sequence.
-#
-# - `action`: Execute a predefined action
-#
-#   - ToggleViMode

-#
-#    - Command
-#    - Control
-#    - Option
-#    - Super
-#    - Shift
-#    - Alt
-#
-#    Multiple `mods` can be combined using `|` like this:
-#       `mods: Control|Shift`.
-#    Whitespace and capitalization are relevant and must match the example.
-#
-# - `mode`: Indicate a binding for only specific terminal reported modes
-#
-#    This is mainly used to send applications the correct escape sequences
-#    when in different modes.
-#
-#    - AppCursor
-#    - AppKeypad
-#    - Search
-#    - Alt
-#    - Vi
-#
-#    A `~` operator can be used before a mode to apply the binding whenever
-#    the mode is *not* active, e.g. `~Alt`.
-#
-# Bindings are always filled by default, but will be replaced when a new
-# binding with the same triggers is defined. To unset a default binding, it can
-# be mapped to the `ReceiveChar` action. Alternatively, you can use `None` for
-# a no-op if you do not wish to receive input characters for that binding.
-#
-# If the same trigger is assigned to multiple actions, all of them are executed
-# in the order they were defined in.

+## 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.

+### 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.

-
-# List with all available hints
-#
-# Each hint must have any of `regex` or `hyperlinks` field and either an
-# `action` or a `command` field. The fields `mouse`, `binding` and
-# `post_processing` are optional.
-#
-# The `hyperlinks` option will cause OSC 8 escape sequence hyperlinks to be
-# highlighted.
-#
-# The fields `command`, `binding.key`, `binding.mods`, `binding.mode` and
-# `mouse.mods` accept the same values as they do in the `key_bindings` section.
-#
-# The `mouse.enabled` field controls if the hint should be underlined while
-# the mouse with all `mouse.mods` keys held or the vi mode cursor is above it.
-#
-# If the `post_processing` field is set to `true`, heuristics will be used to
-# shorten the match if there are characters likely not to be part of the hint
-# (e.g. a trailing `.`). This is most useful for URIs and applies only to
-# `regex` matches.
-#
-# Values for `action`:
-#   - Copy
-#       Copy the hint's text to the clipboard.
-#   - Paste
-#       Paste the hint's text to the terminal or search.
-#   - Select

-#
-# Mouse bindings are specified as a list of objects, much like the key
-# bindings further below.
-#
-# To trigger mouse bindings when an application running within Alacritty
-# captures the mouse, the `Shift` modifier is automatically added as a
-# requirement.
-#
-# Each mouse binding will specify a:
-#
-# - `mouse`:
-#
-#   - Middle
-#   - Left
-#   - Right
-#   - Numeric identifier such as `5`
-#
-# - `action` (see key bindings for actions not exclusive to mouse mode)
-#
-# - Mouse exclusive actions:
-#
-#   - ExpandSelection
-#       Expand the selection to the current mouse cursor location.
-#
-# And optionally:
-#
-# - `mods` (see key bindings)
-#mouse_bindings:
-#  - { mouse: Right,                 action: ExpandSelection }
-#  - { mouse: Right,  mods: Control, action: ExpandSelection }
-#  - { mouse: Middle, mode: ~Vi,     action: PasteSelection  }
-
-# Key bindings
-#
-# Key bindings are specified as a list of objects. For example, this is the
-# default paste binding:
-#
-# `- { key: V, mods: Control|Shift, action: Paste }`
-#
-# Each key binding will specify a:
-#
-# - `key`: Identifier of the key pressed
-#
-#    - A-Z
-#    - F1-F24
-#    - Key0-Key9
-#
-#    A full list with available key codes can be found here:
-#    https://docs.rs/winit/*/winit/event/enum.VirtualKeyCode.html#variants
-#
-#    Instead of using the name of the keys, the `key` field also supports using
-#    the scancode of the desired key. Scancodes have to be specified as a
-#    decimal number. This command will allow you to display the hex scancodes
-#    for certain keys:
-#
-#       `showkey --scancodes`.
-#
-# Then exactly one of:
-#
-# - `chars`: Send a byte sequence to the running application
-#
-#    The `chars` field writes the specified string to the terminal. This makes
-#    it possible to pass escape sequences. To find escape codes for bindings
-#    like `PageUp` (`"\x1b[5~"`), you can run the command `showkey -a` outside
-#    of tmux. Note that applications use terminfo to map escape sequences back
-#    to keys. It is therefore required to update the terminfo when changing an
-#    escape sequence.
-#
-# - `action`: Execute a predefined action
-#
-#   - ToggleViMode
-#   - SearchForward
-#       Start searching toward the right of the search origin.

-#
-#    - Command
-#    - Control
-#    - Option
-#    - Super
-#    - Shift
-#    - Alt
-#
-#    Multiple `mods` can be combined using `|` like this:
-#       `mods: Control|Shift`.
-#    Whitespace and capitalization are relevant and must match the example.
-#
-# - `mode`: Indicate a binding for only specific terminal reported modes
-#
-#    This is mainly used to send applications the correct escape sequences
-#    when in different modes.
-#
-#    - AppCursor
-#    - AppKeypad
-#    - Search
-#    - Alt
-#    - Vi
-#
-#    A `~` operator can be used before a mode to apply the binding whenever
-#    the mode is *not* active, e.g. `~Alt`.
-#
-# Bindings are always filled by default, but will be replaced when a new
-# binding with the same triggers is defined. To unset a default binding, it can
-# be mapped to the `ReceiveChar` action. Alternatively, you can use `None` for
-# a no-op if you do not wish to receive input characters for that binding.
-#
-# If the same trigger is assigned to multiple actions, all of them are executed
-# in the order they were defined in.
