My NixOS configuration

This is my repo that contains my configuration files for my machines (aka dotfiles) This repository contains configuration for three hosts currently

Ryzen desktop
My portable laptop
My server

All hosts runs NixOS and it’s managed by Nix Flakes. home-manager is used to manage user environment. I try to install programs/services in user level as much as possible. I use xmonad as window manager for Desktop and Laptop, while server is headless.

Prequisites

NixOS	Requires a NixOS environment to install Download live environment here
Nix flakes	Requires nix flakes to install this config Enable flakes
Emacs	Emacs is optional, required to generate files from this document

To generate actual files, open this file in emacs and execute M-x org-babel-tangle, binded to C-c C-v t You can install this config in NixOS running nixos-rebuild switch --flake at repository root.

You can also use cmake to make things easier

make	Executes the same command as `make build`
make build	Generate files from this document using emacs
make install	Install this config based on hostname
make desktop1	Install Desktop configs
make laptop1	Install laptop configs
make server1	Install server configs

You can use SPC m . in doom-emacs to navigate headlines faster. If you just want to navigate my config, Please don’t use GitHub preview. Open this file in emacs, or just go here from browser (generated HTML file). I keep in sync a HTML file based on this document, thanks to https://github.com/fniessen/org-html-themes

It’s much easier to read than GitHub preview.

All files generated from README.org except configuration.nix(s) are read-only. Made an exception for configuration.nix(s) because NixOS reinstall requires to edit Partition UUID.

[1/8]TODOs

Document xmobar

Document custom packages

Document configuration.nix/home.nix

Document emacs-anywhere

Document neovim and coc-settings.json

Document flashfocus

Document vifm

Nigthly neovim doesn’t build. Maybe just switch to available overlay

Flake

A flake is (usually) a Git repository that contains a file named flake.nix at root. This repository is compatible with nix flakes. The following code is the base code of flake.nix file.

# This file is generated from "README.org"
{
  description = "NixOS configuration for all machines";

  <<flake-inputs>>

  outputs = inputs@{ self, home-manager, nur, nixpkgs, ... }:
    let
      inherit (builtins) listToAttrs attrValues attrNames readDir;
      inherit (nixpkgs) lib;
      inherit (lib) removeSuffix;

      <<nixpkgs-config>>

      <<flake-defaults>>
    in
    {
      <<flake-overlays>>

      nixosConfigurations = {
        <<desktop1>>
        <<laptop1>>
        <<server1>>
      };
    };
}

Flake inputs

Flakes provides a better approach than channel to manage nixpkgs and overlays. It’s called inputs. Channels aren’t pinned in the config. When updating nixpkgs, you have to run this command nix-channel --update locally everytime. Therefore, nixpkgs revision differs from machine to machine, making not fully reproducible. Using nix flakes, All inputs are automatically pinned at specific revision in flake.lock file at repository root to guarantee reproducibility. This can also be achieved by manually pinning nixpkgs at specific revision using overlays. But flakes does it automatically, without having to update rev and sha256 manually everytime. You can update inputs easily like this: nix flake --update-input nixpkgs

inputs = {
  home-manager = {
    url = "github:rycee/home-manager/release-20.09";
    inputs = {
      nixpkgs.follows = "nixpkgs";
    };
  };
  nur.url = "github:nix-community/NUR";
  emacs-overlay.url = "github:nix-community/emacs-overlay";

  nixpkgs.url = "github:nixos/nixpkgs/nixos-20.09";
  unstable.url = "github:nixos/nixpkgs/nixos-unstable";
  master.url = "github:nixos/nixpkgs/master";
};

nixpkgs config

Configs specific for default pkgs Set system arch to x86_64, import overlays from here

pkgs = (import nixpkgs) {
  system = "x86_64-linux";
  config = {
    <<nixpkgs-globalconfigs>>
  };
  overlays = attrValues self.overlays;
};

Configs that is also applied to unstable and master Allow installation for non-free software(also known as proprietary software), etc etc

allowUnfree = true;
<<retroarch-cores>>

import overlays

This code searchs ./overlays directory for nix files and automatically imports the files. NUR, nixos-unstable, nixpkgs master are imported as package set of pkgs here. Packages from these package sets can be referred like pkgs.unstable.fish pkgs.master.discord pkgs.nur.repos.rycee.firefox-addons This have a benefit than just importing the same way as pkgs like {pkgs, unstable, master, ... }:. If you import unstable just like pkgs, idk why, but it can’t be imported from overlays. So it can’t be used to override packages of home-manager modules. Importing as package set makes it possible and it’s more convenient.

overlays =
  let
    overlayFiles = listToAttrs (map
      (name: {
        name = removeSuffix ".nix" name;
        value = import (./overlays + "/${name}");
      })
      (attrNames (readDir ./overlays)));
  in

          };
        };
      };

          };
        };

Machines

These are the codes that evaluates a NixOS configuration for tools like nixos-rebuild for each machines. It imports modules (that contains configuration for) for each machines.

Desktop

desktop1 = nixpkgs.lib.nixosSystem {
  system = "x86_64-linux";
  modules =
    [
      defaults
      ./machines/maindesktop/configuration.nix

            ];
          };
        })
    ];
  inherit pkgs;
};

Laptop

laptop1 = nixpkgs.lib.nixosSystem {
  system = "x86_64-linux";
  modules =
    [
      defaults
      ./machines/mainlaptop/configuration.nix

            ];
          };
        })

          ];
        };
      })
    ];
  inherit pkgs;
};

Nix

Configure Nix package manager

# This file is generated from "README.org"
{ pkgs, ... }:
{
  <<nix-package>>

  nix.extraOptions = ''
    <<nix-enable-flakes>>
    builders-use-substitutes = true
  '';
  <<nix-allowed-users>>
  <<nix-trusted-users>>
}

Enable flakes

Select Nix package that contains flakes

nix.package = pkgs.nixFlakes;

Enable nix flakes(flakes is still a experimental feature.)

experimental-features = nix-command flakes

Allowed users

A list of names of users that are allowed to connect to the Nix daemon.

nix.allowedUsers = [ "@wheel" ];

Trusted users

A list of names of users that have additional rights when connecting to the Nix daemon. Add user here to use cachix and run nixos-rebuild from that user.

nix.trustedUsers = [ "root" "@wheel" ];

Enable lorri

lorri is a nix-shell replacement with fast direnv integration

services.lorri.enable = true;

Integrate lorri direnv with fish shell

For direnv to work properly it needs to be hooked into the shell. Once the hook is configured, restart your shell for direnv to be activated.

eval (direnv hook fish)

Overlays

Overrides

override nixpkgs packages. useful for home-manager modules.

# This file is generated from "README.org"
final: prev:
{
  inherit (final.unstable) lua;
  inherit (final.unstable) fish;
  inherit (final.master) youtube-dl;
  inherit (final.master) mpv;
  inherit (final.unstable) fzf;
}

Custom packages

Import custom packages into nixpkgs, so you can treat just like any other package.

# This file is generated from "README.org"
final: prev: rec {
  apple-color-emoji = prev.callPackage ../packages/apple-color-emoji { };
  tamzen-nerdfont = prev.callPackage ../packages/tamzen-nerdfont { };
  palenight-gtk-theme = prev.callPackage ../packages/palenight-gtk-theme { };
  vifmimg = prev.callPackage ../packages/vifmimg { };
}

Attribute overrides

neofetch

Install latest neofetch with new NixOS logo

# This file is generated from "README.org"
final: prev:
{
  neofetch = prev.neofetch.overrideAttrs (old: rec {
    version = "unstable-2020-11-02";
    src = prev.fetchFromGitHub {
      owner = "dylanaraps";
      repo = "neofetch";
      rev = "5dfce0f9c3068d4d8a49d0b7182bdace61b8f4d0";
      sha256 = "131r07wllkvrcgw0ndyf5avqpzqkym56ii0qck6qyjfa8ylx6s31";
    };
  });
}

Input

Keyboard

Xorg repeat rate

Default repeat rate is too slow. Change it

services.xserver.autoRepeatDelay = 200;
services.xserver.autoRepeatInterval = 25;

Dvorak

I use Dvorak layout on HHKB. Dvorak layout is a ergonomic alternative for qwerty layout that requires less movement. My keybinds are configured with HHKB Dvorak usage in mind. I didn’t remapped vim(or evil-mode) keys(hjkl) because it already feels natural as is.

Console config

console.keyMap = "dvorak";

Xorg config

services.xserver.layout = "us";
services.xserver.xkbVariant = "dvorak";

home-manager config

home.keyboard = {
  layout = "us";
  variant = "dvorak";
};

IME

Install Japanese IME

i18n.inputMethod.enabled = "fcitx";
i18n.inputMethod.fcitx.engines = with pkgs.fcitx-engines; [ mozc ];

Thinkpad

I can’t live without HHKB-ish layout. I remap my ThinkPad layout:

xkb_keymap {
 xkb_keycodes {
  include "evdev+aliases(qwerty)"
  <ESC> = 49;
  <BKSP> = 51;
  <LCTL> = 37;
  <TLDE> = 9;
  <BKSL> = 22;
 };
 xkb_types { include "complete"};
 xkb_compatibility { include "complete"};
 xkb_symbols { include "pc+us(dvorak)+us(dvorak):2+inet(evdev)+altwin(swap_alt_win)+ctrl(nocaps)" };
 xkb_geometry { include "pc(pc104)"};
};

Symlink it to /etc for convenience

environment.etc."thinkpadlayout.xkb".source = ../../configs/thinkpadlayout.xkb;

Make a systemd service to execute everytime after waking up from restart/sleep

systemd.user.services.xkb-restore = {
  description = "Restore keyboard layout after suspend";
  after = [ "suspend.target" "graphical-session.target" ];
  serviceConfig = {
    Type = "simple";
    Environment = "DISPLAY=:0";
    ExecStartPre = "/usr/bin/env sleep 3";
    ExecStart = "${pkgs.bash}/bin/bash -c \"${pkgs.xorg.xkbcomp}/bin/xkbcomp -i $(${pkgs.xorg.xinput}/bin/xinput list | sed -n 's/.*Translated.*id=\\\([0-9]*\\\).*keyboard.*/\\\1/p') /etc/thinkpadlayout.xkb :0\"";
  };
  wantedBy = [ "suspend.target" "graphical-session.target" ];
};

Trackpad

I use libinput because the better palm detection. It’s a minimal config because trackpad is mostly disabled.

# This file is generated from "README.org"
{
  services.xserver.libinput.enable = true;
  services.xserver.libinput.naturalScrolling = true;
  services.xserver.libinput.disableWhileTyping = true;
  services.xserver.libinput.accelSpeed = "1.000000";
}

keynav

keynav is a program that allows you to control the mouse with keyboard in a very efficient way. One of the big reasons I can live mostly without mouse

services.keynav.enable = true;

Generate keynav config. Super-semicolon to start keynav s to warp cursor m,w,v,z to scroll, think like hjkl on QWERTY keyboard. it’s positioned on bottom right of Dvorak layout

"keynav/keynavrc".text = ''
  super+semicolon start
  s warp
  m click 6
  w click 5
  v click 4
  z click 7
'';

Output

Monitor

Brightness

We need these kernel parameters to be able to control display brightness on ThinkPad

"acpi_osi='!Windows 2012'"
"acpi_backlight=vendor"

Resolution

Scale desktop monitor to 1440p

xsession.profileExtra = "xrandr --output DVI-D-0 --scale-from 2560x1440 --panning 2560x1440";

Scale laptop monitor to 1080p

Fonts

I use Cozette font as editor/terminal font.

Spleen is my choice for TTY font

GohuFont is used only to render nerdfonts.

I think Apple’s emoji font is the best emoji font.

Install fonts:

# This file is generated from "README.org"
{ pkgs, ... }:
{
  fonts.fonts = with pkgs; [
    (nerdfonts.override { fonts = [ "Gohu" ]; })
    unstable.dejavu_fonts
    spleen
    unstable.cozette
    apple-color-emoji
    noto-fonts-cjk
    emacs-all-the-icons-fonts
    etBook
    liberation_ttf_v2
  ];
  <<system-font-config>>
  <<fontconfig-enable>>
  <<fontconfig-allowbitmaps>>
  <<use-embedded-bitmaps>>
  <<enable-font-dir>>
  <<enable-ghostscript-fonts>>
}

Enable fontconfig

If enabled, a fontconfig file will be built pointing to a set of default fonts.

fonts.fontconfig.enable = true;

Default fonts

Set system-wide monospace/emoji font below. Note that setting emoji here is not sufficient to show emoji properly.

fonts.fontconfig = {
  defaultFonts = {
    emoji = [ "Apple Color Emoji" ];
    monospace = [ "Spleen" ];
  };
};

Allow bitmaps

This option is needed to allow usage of bitmap fonts. Like Spleen I use.

fonts.fontconfig.allowBitmaps = true;

Use embedded bitmaps

This option is necessary to make emacs show unicode emojis properly.

fonts.fontconfig.useEmbeddedBitmaps = true;

Enable Font Dir

Create a directory with links to all fonts in /run/current-system/sw/share/X11-fonts

fonts.enableFontDir = true;

Enable ghost script fonts

Add the fonts provided by Ghostscript to the list of system fonts.

fonts.enableGhostscriptFonts = true;

TTY Font

Console fonts needs to be installed here via console.packages to be able to set.

console.packages = with pkgs; [ unstable.spleen ];
console.font = "spleen-6x12";

Emacs fonts

Emacs fonts are set in point(pt) rather than pixel(px) Set doom fixed-pitch font and doom variable pitch font here:

(setq doom-font "CozetteVector-10.5"
      doom-variable-pitch-font "ETBembo-11")

Enable bold and italic

(setq doom-themes-enable-bold t)

(setq doom-themes-enable-italic t)

Set centaur-tabs tabline font

(centaur-tabs-change-fonts "Liberation Sans" 110)

Set custom set faces here modeline font dashboard font color avy hinting font. org-mode title font size

(custom-set-faces!
  '(mode-line :family "Liberation Sans" :height 105)
  '(mode-line-inactive :family "Liberation Sans" :height 105)
  '(doom-dashboard-menu-title :foreground "#c792ea")
  '(org-document-title :height 225)
  )

Set treemacs fonts to Liberation Sans

(setq doom-themes-treemacs-enable-variable-pitch nil)
(custom-set-faces!
  '(treemacs-root-face :family "Liberation Sans" :height 105)
  '(treemacs-git-unmodified-face :family "Liberation Sans" :height 105)
  '(treemacs-git-modified-face :family "Liberation Sans" :height 105)
  '(treemacs-git-renamed-face :family "Liberation Sans" :height 105)
  '(treemacs-git-ignored-face :family "Liberation Sans" :height 105)
  '(treemacs-git-untracked-face :family "Liberation Sans" :height 105)
  '(treemacs-git-added-face :family "Liberation Sans" :height 105)
  '(treemacs-git-conflict-face :family "Liberation Sans" :height 105)
  '(treemacs-directory-face :family "Liberation Sans" :height 105)
  '(treemacs-directory-collapsed-face :family "Liberation Sans" :height 105)
  '(treemacs-file-face :family "Liberation Sans" :height 105)
  '(treemacs-tags-face :family "Liberation Sans" :height 105)
  )

Set emoji and nerdfont(extrafonts):

(add-hook! 'doom-load-theme-hook
           :append
           (defun my/init-extra-fonts-h(&optional frame)
             (with-selected-frame (or frame (selected-frame))
               (set-fontset-font t 'symbol "CozetteVector" nil)
               (set-fontset-font t 'symbol "Apple Color Emoji" nil 'append)
               (set-fontset-font t 'symbol "GohuFont Nerd Font" nil 'append))))

Add this to config to use unicode emoji inside emacs

(setq emojify-display-style 'unicode)

xmonad prompt fonts

Set xmonad prompt font to Liberation Sans

myFont :: String
myFont = "xft:Liberation Sans:size=14"

Set xmonad emoji prompt font

myEmojiFont :: String
myEmojiFont = "xft:Apple Color Emoji:size=14"

Alacritty Fonts

programs.alacritty.settings.font = {
  normal = {
    family = "CozetteVector";
    style = "Regular";
  };
  bold = {

    x = 0;
    y = 0;
  };
  glyph_offset = {
    x = 0;

  tabs.selected = "10.5pt CozetteVector";
  tabs.unselected = "10.5pt CozetteVector";
  #tabs = "10.5pt CozetteVector";
};

fontconfig

Font configs that can’t be configured using nix options belongs here.

10-symbols.conf

Use nerdfont as fallback font

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
    <alias>
        <family>Cozette</family>
        <prefer>
            <family>GohuFont Nerd Font</family>
        </prefer>
    </alias>
</fontconfig>

65-nonlatin.conf

This configures Japanese font. This makes programs use Noto Sans CJK JP for Japanese automatically. Therefore no need to configure Japanese font as main font.

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
    <!-- Default font for the ja_JP locale (no fc-match pattern) -->
    <match>

    </alias>
</fontconfig>

10-prefer-emoji.conf

Seems like this user-level config is needed to programs use Apple Color Emoji for every emojis.

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
    <match>
        <edit name="family" mode="prepend">

</fontconfig>

Dunst(Notifications) font

services.dunst.settings.global.font = "Liberation Sans 14";

Wallpapers

Desktop wallpaper pictures/wallpaper1.png

Lock screen wallpaper pictures/wallpaper2.png

Wallpaper files

Put (symlink) files into /etc. It makes easy to set wallpapers from any machines.

"wallpapers/wallpaper1.png".source = ../../pictures/wallpaper1.png;
"wallpapers/wallpaper2.png".source = ../../pictures/wallpaper2.png;
"wallpapers/wallpaper2-1080.png".source = ../../pictures/wallpaper2-1080.png;

Lock screen

Set 1440p lock screen wallpaper

background-image = "/etc/wallpapers/wallpaper2.png"

Set a 1080p equivalent

background-image = "/etc/wallpapers/wallpaper2-1080.png"

Set wallpaper

First, set fallback wallpaper in case config isn’t set

spawnOnce "feh --bg-fill /etc/wallpapers/wallpaper1.png &"

Then, apply nitrogen config

spawnOnce "nitrogen --restore &"

Icons

Cursors

Alacritty cursor

Set cursor shape

programs.alacritty.settings.cursor = {
  style = "Beam";
};

Enable custom cursor colors

programs.alacritty.settings.custom_cursor_colors = true;

Set x11 cursor

First, import this module in xmonad

import           XMonad.Util.Cursor             ( setDefaultCursor )

Use that module to set cursor at startuphook

setDefaultCursor xC_left_ptr

Opacity

Programs that doesn’t have opacity option, or the opacity option doesn’t work great(like PGTK emacs) can be set opacity using picom with following code:

services.picom.opacityRule = [
    "80:class_g  = 'Zathura'"
    "80:class_g  = 'TelegramDesktop'"
    "80:class_g  = 'Discord'"
    "80:class_g  = 'Emacs'"
    "100:class_g = 'keynav'"
];

Blur

Configure blur method and strength for translucent programs. I use dual kawase blur.

blur:
{
    method = "kawase";
    strength = 8;
    background = false;
    background-frame = false;
    background-fixed = false;
};

Blur exclude

Set programs to exclude from background blur here. Exclude keynav because it’s not intended to be recognized as window and it becomes buggy.

blur-background-exclude = [
    "class_g = 'keynav'"
];

Alacritty opacity

Set Alacritty opacity. Window opacity as a floating point number from 0.0 to 1.0 The value 0.0 is completely transparent and 1.0 is opaque.

programs.alacritty.settings.background_opacity = 0.8;

Emacs opacity

Set to nil, let picom manage opacity because pure gtk emacs doesn’t work great with opacity option.

(set-frame-parameter nil 'alpha nil) ;; let picom manage it

Border

Border width

Set the width of window border in px

myBorderWidth :: Dimension
myBorderWidth = 2

Window border color

Set border color for windows

myNormalBorderColor :: String
myNormalBorderColor = "#2b2a3e"

Set border color for focused window

myFocusedBorderColor :: String
myFocusedBorderColor = "#c792ea"

Enable rounded borders

Enable rounded borders in picom

round-borders = 1;

Corner radius

Set window corner radius

corner-radius = 18;

Rounded corner exclude

Programs to exclude from rounded corners. Exclude keynav and dock, full screen programs.

rounded-corners-exclude = [
    "window_type = 'dock'",
    "_NET_WM_STATE@:32a *= '_NET_WM_STATE_FULLSCREEN'",
    "class_g = 'keynav'",
];

Rounded borders exclude

Exclude programs from rounded borders. Exclude keynav because it’s not intended to be recognized as window and it becomes buggy.

Install Alacritty

Whether to enable Alacritty

programs.alacritty.enable = true;

Enable true color

xterm-256color describes Xterm with support for 256 colors enabled. set TERM environment variable.

programs.alacritty.settings.env.TERM = "xterm-256color";

Alacritty padding

Blank space added around the window in pixels.

programs.alacritty.settings.window.padding = {
    x = 12;
    y = 0;
};

Dynamic padding

programs.alacritty.settings.window.dynamic_padding = false;

Window decorations

full : Borders and title bar
none: Neither borders nor title bar

programs.alacritty.settings.window.decorations = "none";

Window startup mode

Windowed
Maximized
Fullscreen

programs.alacritty.settings.window.startup_mode = "Windowed";

Scrolling

History sets maximum number of lines in the scrollback buffer. Multiplier sets scrolling distance multiplier.

programs.alacritty.settings.scrolling = {
    history = 10000;
    multiplier = 3;
};

Draw bold text with bright colors

If true, bold text is drawn using the bright color variants. Maybe usable for bitmap fonts?

programs.alacritty.settings.draw_bold_text_with_bright_colors = true;

Key bindings

C-S-c to copy, C-S-v to paste C-S-Up to scroll upwards. C-S-Down to scroll downwards.

programs.alacritty.settings.key_bindings = [
  {
    key = "V";
    mods = "Control|Shift";
    action = "Paste";
  }
  {
    key = "C";
    mods = "Control|Shift";
    action = "Copy";
  }
  {
    key = "Up";
    mods = "Control|Shift";

vterm

vterm is fully-fledged terminal emulator inside GNU Emacs based on libvterm, a C library. As a result of using compiled code (instead of elisp), emacs-libvterm is fully capable, fast, and it can seamlessly handle large outputs. Just think like running Konsole or Gnome Terminal inside emacs

Install vterm

vterm uses extrenal compiled code, unlike other emacs packages. So, you need to install vterm package to use.

programs.emacs.extraPackages = (epkgs: [ epkgs.vterm ]);

fish shell configuration

# Some of the most useful features in emacs-libvterm require shell-side
# configurations. The main goal of these additional functions is to enable the
# shell to send information to `vterm` via properly escaped sequences. A
# function that helps in this task, `vterm_printf`, is defined below.

function vterm_printf;
    if [ -n "$TMUX" ]
        # tell tmux to pass the escape sequences through
        # (Source: http://permalink.gmane.org/gmane.comp.terminal-emulators.tmux.user/1324)
        printf "\ePtmux;\e\e]%s\007\e\\" "$argv"
    else if string match -q -- "screen*" "$TERM"
        # GNU screen (screen, screen-256color, screen-256color-bce)
        printf "\eP\e]%s\007\e\\" "$argv"
    else
        printf "\e]%s\e\\" "$argv"
    end
end

# Completely clear the buffer. With this, everything that is not on screen
# is erased.

Git

This directory is a git repository, nixpkgs is a git repository, Emacs, Linux is developed in git repository, most free(as in freedom) softwares uses Git nowadays. Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

  <<git-package>>
  <<git-default-branch>>
  <<git-push-ssh>>
  <<git-name-mail>>
}

Enable Git

Turn on to install Git

programs.git.enable = true;

Git Package

I use Git from nixos-unstable

programs.git.package = pkgs.unstable.git;

Git Default Branch

Many communities are renaming Default Git Branch from master to main to remove racially-charged language from software. github/renaming Github to replace “master” with alternative term to avoid slavery references It’s very easy to do that on user-level. Why not start using main from today? There aren’t any reason to not start using main for new personal projects.

programs.git.extraConfig.init.defaultBranch = "main";

Use SSH only when pushing

I use SSH to push into Git repository. This config Git default to SSH to push. Note that it is pushinsteadOf If you use just insteadOf, it will ask SSH key even when cloning.

programs.git.extraConfig.url."git@github.com:" = {
    pushinsteadOf = "https://github.com/";
};

User name,Email

Git uses email to identify your commits, and associate commits with your accounts e.g. GitHub GitLab Email and User Name will be visible in any your commits. If you want to keep your real name private, use any text like GitHub user name. To GitHub/GitLab be able to associate your commits with your accounts, you have to either:

Use your real mail address register on GitHub/GitLab
Use noreply mail addres

I’m still not ready to migrate to GitLab, so I use GitHub noreply mail address

programs.git.userName = "btwiusegentoo";
programs.git.userEmail = "66811008+btwiusegentoo@users.noreply.github.com";

bat

Turn on to install fzf

programs.fzf.enable = true;

Fish shell integration

Turn on to enable fish shell integration. Most usable one is <C-t> to search current directory.

programs.fzf.enableFishIntegration = true;

Use fd instead of default find

Requires fd installed. It is faster than default find

programs.fzf.defaultCommand = "fd --type f";

lsd

Simply put, lsd is a better ls command with colors, nerdfont icons, written in Rust

# This file is generated from "README.org"
{
  <<lsd-enable>>
  <<lsd-aliases>>
}

Enable lsd

programs.lsd.enable = true;

lsd aliases

Turn on to enable lsd aliases. I want to use my own aliases, so I disable it.

programs.lsd.enableAliases = false;

tmux

tmux is a terminal multiplexer. It lets you switch easily between several programs in one terminal, detach them (they keep running in the background) and reattach them to a different terminal.

{ pkgs, ... }:

{
  <<tmux-enable>>
  programs.tmux.plugins = with pkgs; [
    <<vim-tmux-navigator>>
    <<tmux-prefix-highlight>>
  ];
  <<tmux-vi-keymode>>
  programs.tmux.extraConfig = ''

      <<tmux-colors-source>>
      <<tmux-keybinds>>
  '';
}

Enable tmux

programs.tmux.enable = true;

Vim tmux navigator

This plugin provides the following mappings which allow you to move between Vim panes and tmux splits seamlessly like this:

<ctrl-h> => Left
<ctrl-j> => Down
<ctrl-k> => Up
<ctrl-l> => Right
<ctrl-\> => Previous split

install plugin

tmuxPlugins.vim-tmux-navigator

prefix highlight

Plugin that highlights when you press tmux prefix key. Install:

tmuxPlugins.prefix-highlight

vi key mode

Enable a set of vi-like bindings for navigating a buffer in a window

programs.tmux.keyMode = "vi";

Enable true color

This is necessary to make neovim true color work inside tmux

set-option -g default-terminal "screen-256color"
set -ga terminal-overrides ",*256col*:Tc"

keybinds

I use Ctrl Space as prefix

set-option -g prefix C-Space
bind C-Space send-prefix
bind s split-window -h
bind v split-window -v

xmonad

I use xmonad, the very hackable dynamically tiling window manager written/configured in Haskell Tiling window manager automates the window organization

Install xmonad/ Set config file path

home-manager have a xmonad module. install it:

# This file is generated from "README.org"
{
  xsession.windowManager.xmonad = {
    enable = true;
    enableContribAndExtras = true;
    config = ../../haskell/xmonad.hs;
  };
}

imports

These are the modules that I import so I can use that functionality later It’s always a better practice to use explicit imports for Haskell

Config

Set xmonad prompt attributes See here for documentation

myXPConfig = def { font              = myFont
                 <<xmonad-prompt-color>>
                 , promptKeymap      = myXPKeymap
                 , promptBorderWidth = 0
                 , position          = Top
                 , height            = myPromptHeight
                 , autoComplete      = Nothing
                 , searchPredicate   = fuzzyMatch
                 , alwaysHighlight   = True
                 }

Same config as above, but with emoji font for unicode prompt

myEmojiXPConfig = def { font              = myEmojiFont
                      <<xmonad-prompt-color>>
                      , promptKeymap      = myXPKeymap
                      , promptBorderWidth = 0
                      , position          = Top
                      , height            = myPromptHeight
                      , autoComplete      = Nothing
                      , searchPredicate   = fuzzyMatch
                      , alwaysHighlight   = True
                      }

Set default terminal

Set Alacritty as default terminal in xmonad

myTerminal :: String
myTerminal = "alacritty"

Set gaps

Set the gap between windows. spacingRaw adds spacing to windows. This function needs to be applied to the layout at layoutHook. I don’t apply it to Full screen layout

myGaps = spacingRaw False (Border 4 4 4 4) True (Border 4 4 4 4) True

Keybindings

Set Super key as xmonad mod key

myModMask :: KeyMask
myModMask = mod4Mask

I use EZConfig that allows simpler, emacs-style keybinding description See here for further information

import           XMonad.Util.EZConfig           ( additionalKeysP )

    )
  ]

Layouts

Set the layouts avaliable to use. Make sure to apply gaps(spacingRaw) from here

myLayout = avoidStruts $ smartBorders
  (tiledgaps ||| bspgaps ||| Mirror tiledgaps ||| spiralgaps ||| Full)
 where
  tiledgaps  = myGaps $ Tall nmaster delta ratio

  -- window number in master pane
  nmaster    = 1

  -- percent of screen to increment by when resizing panes
  delta      = 2 / 100

  -- default proportion of screen occupied by master pane
  ratio      = 1 / 2

  bspgaps    = myGaps emptyBSP
  spiralgaps = myGaps $ spiral (6 / 7)

Startups(autostart)

These are the commands that xmonad executes on startup. Set the wallpaper, cursor, etc here I run compositor(picom) and few programs like keynav as systemd service because home-manager module does that. But usually we start all these programs here

myStartupHook = do
  <<xmonad-fallback-wallpaper>>
  <<xmonad-set-wallpaper>>
  <<xmonad-set-cursor>>
  -- spawn Japanese IME
  spawnOnce "fcitx -d &"
  -- start screen locker
  spawnOnce "light-locker --lock-on-suspend &"
  -- window animation
  spawnOnce "flashfocus &"

Scratchpads

Import scratchpad module

import           XMonad.Util.NamedScratchpad

This configures floating scratchpads for several programs:

myScratchPads =
  [ NS "terminal" spawnTerm   findTerm   manageTerm
  , NS "mixer"    spawnMixer  findMixer  manageMixer
  , NS "bottom"   spawnbottom findbottom managebottom
  , NS "vifm"     spawnvifm   findvifm   managevifm
  ]
 where
  centralh   = 0.9
  centralw   = 0.9
  centralt   = 0.95 - centralh
  centrall   = 0.95 - centralw

  spawnTerm  = myTerminal ++ " --title=terminalScratchpad"
  findTerm   = title =? "terminalScratchpad"
  manageTerm = customFloating $ W.RationalRect l t w h
   where
    h = 0.3
    w = 1
    t = 0
    l = (1 - w) / 2

  spawnMixer = myTerminal ++ " --title=mixerScratchpad" ++ " -e ncpamixer"
  findMixer  = title =? "mixerScratchpad"
  manageMixer =
    customFloating $ W.RationalRect centrall centralt centralw centralh

  spawnbottom = myTerminal ++ " --title=bottomScratchpad" ++ " -e btm"
  findbottom  = title =? "bottomScratchpad"
  managebottom =
    customFloating $ W.RationalRect centrall centralt centralw centralh

  spawnvifm =
    myTerminal ++ " --title=vifmScratchpad" ++ " -e bash -c 'vifmrun'"
  findvifm = title =? "vifmScratchpad"
  managevifm =
    customFloating $ W.RationalRect centrall centralt centralw centralh

ManageHook

Set rules for certain programs. e.g.Make certain program always appear at certain workspace, Force certain program(GIMP here) to always float

myManageHook =
  composeAll
      [ className =? "Gimp" --> doFloat
      , resource =? "desktop_window" --> doIgnore
      , isFullscreen --> doFullFloat
      ]
    <+> namedScratchpadManageHook myScratchPads

Mouse

Mouse configuration. I rarely use it, my mouse is mostly disabled so I won’t document it.

myFocusFollowsMouse :: Bool
myFocusFollowsMouse = True
myClickJustFocuses :: Bool
myClickJustFocuses = False

myMouseBindings XConfig { XMonad.modMask = modm } = M.fromList

    -- mod-button1, Set the window to floating mode and move by dragging
  [ ( (modm, button1)
    , \w -> focus w >> mouseMoveWindow w >> windows W.shiftMaster
    )

    -- mod-button2, Raise the window to the top of the stack
  , ((modm, button2), \w -> focus w >> windows W.shiftMaster)

    -- mod-button3, Set the window to floating mode and resize by dragging
  , ( (modm, button3)
    , \w -> focus w >> mouseResizeWindow w >> windows W.shiftMaster
    )

    -- you may also bind events to the mouse scroll wheel (button4 and button5)
  ]

Function to get active layout description

Get active layout. This used by M-. ~”M-,”~ keybind to determine if it’s BSP layout or not.

getActiveLayoutDescription :: X String
getActiveLayoutDescription = do
  workspaces <- gets windowset
  return $ description . W.layout . W.workspace . W.current $ workspaces

xmobar

xmobar is lightweight status bar that is written/configured in Haskell. Since it serves well my usage, it can be configured in Haskell, I use it.

Emacs

I use emacs (specifically, doom-emacs) as main text editor

doom-emacs is an Emacs framework, which is preconfigured with evil-mode(vim keybindings) that allows me to use heavily customized emacs ootb Doom starts up really quickly,because it tries to lazy load a lot of packages, byte compiles your configuration.

My emacs config is still work in progress, I change it often.

So, I choose to install doom-emacs in traditional way instead of using nix-doom-emacs git clone --depth 1 https://github.com/hlissner/doom-emacs ~/.emacs.d ~~/.emacs.d/bin/doom install~

Install Emacs nativecomp pgtk

Install emacs itself

programs.emacs.enable = true;

Use emacs native comp pgtk package from Overlay here

programs.emacs.package = pkgs.emacsPgtkGcc;

You have to add this to init.el and config.el to fix nativecomp in Nix

(setq comp-async-env-modifier-form "")

Enable Emacs daemon

I use emacs as daemon. This allows to use emacs in a very flexible way(e.g.Edit text on qutebrowser using emacs ) Note that enabling socketActivation produces error when running nixos-rebuild with latest unstable emacs

services.emacs = {
  enable = true;
  client = {
    enable = true;
    arguments = [ "-c" ];
  };
  socketActivation.enable = false;
};

Select doom-emacs modules

Control what Doom modules are enabled and what order they load in. Run doom sync after modifying it

Commentary

To install a package with Doom you must declare them here and run ‘doom sync’ on the command line, then restart Emacs for the changes to take effect – or use ‘M-x doom/reload’.

To install SOME-PACKAGE from MELPA, ELPA or emacsmirror:

(package! some-package)

To install a package directly from a remote git repo, you must specify a :recipe. You’ll find documentation on what `:recipe’ accepts here: https://github.com/raxod502/straight.el#the-recipe-format

(package! another-package
  :recipe (:host github :repo "username/repo"))

If the package you are trying to install does not contain a PACKAGENAME.el file, or is located in a subdirectory of the repo, you’ll need to specify :files in the :recipe

(package! this-package
  :recipe (:host github :repo "username/repo"
           :files ("some-file.el" "src/lisp/*.el")))

If you’d like to disable a package included with Doom, you can do so here with the :disable property:

(package! builtin-package :disable t)

You can override the recipe of a built in package without having to specify all the properties for :recipe. These will inherit the rest of its recipe from Doom or MELPA/ELPA/Emacsmirror:

(package! builtin-package :recipe (:nonrecursive t))
(package! builtin-package-2 :recipe (:repo "myfork/package"))

Specify a :branch to install a package from a particular branch or tag. This is required for some packages whose default branch isn’t ‘master’ (which our package manager can’t deal with; see radian-software/straight.el#279

(package! builtin-package :recipe (:branch "develop"))

Use :pin to specify a particular commit to install.

(package! builtin-package :pin "1a2b3c4d5e")

Doom’s packages are pinned to a specific commit and updated from release to release. The `unpin!’ macro allows you to unpin single packages…

(unpin! pinned-package)

…or multiple packages

(unpin! pinned-package another-pinned-package)

…Or all packages (NOT RECOMMENDED; will likely break things)

(unpin! t)

Disable line number

Disable line number mode because it causes lag

(setq display-line-numbers-type nil)

Indent

Disable tab and use 4 space

(setq-default

Centaur Tabs

Centaur tabs is a functional, efficient, customizable tab plugin for emacs

Install fork compatible with emacs daemon(packages.el)

(package! centaur-tabs

Hook centaur tabs at doom startup

:hook (doom-first-file . centaur-tabs-mode)

Scrolling (with the mouse wheel) past the end of the tab list replaces the tab list with that of another Doom workspace. This prevents that:

(setq centaur-tabs-cycle-scope 'tabs)

Disable centaur tabs in certain buffers(doom-dashboard and popup buffer here)

(add-hook '+doom-dashboard-mode-hook #'centaur-tabs-local-mode)
(add-hook '+popup-buffer-mode-hook #'centaur-tabs-local-mode)

Integrate with projectile You can group your tabs by Projectile’s project. Just use the following function in your configuration:

Web Browser

qutebrowser

I use qutebrowser as main browser. qutebrowser is a keyboard-focused(Vim-style key bindings) browser with a minimal GUI based on Chromium(qtwebengine).

}

Install qutebrowser

Turn on this option to install qutebrowser

programs.qutebrowser.enable = true;

Search engine

While the default option (DuckDuckGo) is great, I’m still not ready to switch to it. So, I choose to use Google as default search engine qutebrowser can set multiple search engines, but I don’t use it.

programs.qutebrowser.searchEngines = {
    DEFAULT = "https://google.com/search?q={}";
};

GPU acceleration

Idk why, these gpu acceleration flags are disabled in qtwebengine by default (See Issue 5378) These flags makes a significant difference in perfomance, CPU usage, and battery life. Especially usable for laptop. Enable it.

programs.qutebrowser.settings.qt.args = [ "enable-native-gpu-memory-buffers" "enable-gpu-rasterization" "use-gl=egl" "ignore-gpu-blacklist" "num-raster-threads=4" ];

Youtube playback with mpv

Youtube video uses vp9 codec nowadays, that can’t be playbacked in Linux with GPU acceleration. That can be workaronuded by using Plugin to force h264 in Firefox. But, qutebrowser can’t. So, just play the video in mpv as alternative workaround. Press yd to open current youtube video URL in mpv

programs.qutebrowser.keyBindings.normal."yd" = "spawn mpv --ytdl-format='bestvideo[height<=?1080][vcodec!=vp9]+bestaudio/best' {url}";

Or, yf use hints to select and open youtube video in mpv

programs.qutebrowser.keyBindings.normal."yf" = "hint links spawn mpv --ytdl-format='bestvideo[height<=?1080][vcodec!=vp9]+bestaudio/best' --force-window yes {hint-url}";

Qutebrowser start page

Set my own start page

programs.qutebrowser.settings.url.start_pages = [ "https://btwiusegentoo.github.io/start.html" ];
programs.qutebrowser.settings.url.default_page = "https://btwiusegentoo.github.io/start.html";

Max completion history items

Set qutebrowser max completion items from history to 30

programs.qutebrowser.settings.completion.web_history.max_items = 30;

Default zoom

Even with 1080p xrandr scale in laptop or 1440p xrandr scale in desktop, I feel everything is too big(possibly I’m weird) So I have to set default zoom to 90%

programs.qutebrowser.settings.zoom.default = "90%";

Edit text on qutebrowser using emacs

You can write text in qutebrowser using emacs. This is really useful when using Reddit, or writing GitHub issue,etc. Requires Emacs daemon

c.editor.command = ["emacsclient", "-c", "--eval", "(find-file \"{}\")", "(org-mode)"]

Dvorak friendly Hinting

programs.qutebrowser.settings.hints.chars = "aoeuidhtns";

Firefox

Firefox is my backup browser. I Use for certain websites that qutebrowser can’t access(like widevine websites in NixOS), or games, etc.

Tridactyl

Tridactyl is a Firefox plugin that provides Vim key bindings. Makes Firefox usable. Replaces Firefox’s control mechanism with one modelled on Vim.

Let’s install it:

tridactyl

Configuration

Idk why, file based configuration doesn’t work now. Configuration to make it behave like qutebrowser

" Remove local config
sanitise tridactyllocal tridactylsync

" Adjust scroll speed
bind j scrollline -2
bind k scrollline 2
" Set tab move direction same as qutebrowser
bind J tabnext
bind K tabprev
" Use qutebrowser like behavior for new tab :open
bind O fillcmdline tabopen

Install tridactyl configuration into $HOME/.config/tridactyl/tridactylrc

"tridactyl/tridactylrc".text = ''
    <<tridactylrc>>
'';

Start page

Set my own startpage

Use US google search engine

programs.firefox.profiles.default.settings."browser.search.isUS" = true;

Multimedia

mpv

Install mpv

Turn on to install mpv

programs.mpv.enable = true;

Enable hardware decoding

Hardware decoding is not enabled by default because it’s likely to cause issues like tearing, stutter, etc on Low Power GPUs My GPUs are totally fine. Enable it:

programs.mpv.config.hwdec = "auto";
programs.mpv.config.hwdec-codecs = "all";

mpv default volume

Set the startup volume. 0 means silence, 100 means no volume reduction or ampififacion. Negative values can be passed for compatibility, but are treated as 0.

programs.mpv.config.volume = 80;

mpv key bindings

Even though I use Dvorak, I’m vim keybinding user. hjkl feels much better than arrow key. It’s a great idea to control volume and seek video/music with hjkl l already have set to ab-loop for default. So I have to change it.

programs.mpv.bindings = {
    h = "seek -10";
    j = "add volume -2";
    k = "add volume 2";
    l = "seek 10";
    "Ctrl+l" = "ab-loop";

Challenge Response Authentication

challenge response authentication uses a cryptographic protocol that allows to prove that the user knows the password without revealing the password itself. thus, makes the authentication more secure.

services.openssh.challengeResponseAuthentication = true;

X11 forwarding

X11 forwarding is a method to start a graphical apllication installed on a remote system and forward that application to the local system.

services.openssh.forwardX11 = false;

Open firewall

Whether to automatically open the ssh ports in the firewall.

services.picom.package = pkgs.nur.repos.reedrw.picom-next-ibhagwan;

Picom backend

xrender backend uses software rendering. glx uses GPU rendering. It’s obviously that glx is better. round-borders was originally written for xrender backend, but it’s ported to glx kawase-blur was originally written for glx backend. Just use glx.

services.picom.backend = "glx";

Experimental backends

Whether to use the new experimental backends. Currently, new backends feature better vsync with the xrender backend and improved input lag with the glx backend(for non-NVIDIA users). Also, I think dual_kawase blur and rounded borders have better implementation within the experimental backends code.

services.picom.experimentalBackends = true;

Detect Client Opacity

Symlinks

Nix modules to symlink various files included config files

/etc files

This module symlinks files that belongs in /etc. I like to use this path to store icons and wallpapers because this directory /etc is not machine dependent like user’s home folder. That makes possible to share same config that uses these files for more than one machines.

# This file is generated from "README.org"
{
  environment.etc = {
    <<etc-wallpaper-files>>
    # icons
    "icons/cpu.xpm".source = ../../icons/cpu.xpm;

    "icons/volume-mute.xpm".source = ../../icons/volume-mute.xpm;
    "icons/clock.xpm".source = ../../icons/clock.xpm;
    # emojis
