# Desktop
Freedom is a state of mind
Author: SqrtMinusOne

My general desktop environment configuration.

Parts prefixed with (OFF) are not used, but kept for historic purposes. For some reason GitHub’s org renderer ignores TODO status, hence such a prefix. Round brackets instead of square ones to prevent GitHub’s org renderer from screwing up.

## Global customization

### Colors

Most of the colors are from the Palenight theme. Colorcodes are taken from this repo:

color | key | value
--- | --- | ---
black | color0 | #292d3e
red | color1 | #f07178
green | color2 | #c3e88d
yellow | color3 | #ffcb6b
blue | color4 | #82aaff
magenta | color5 | #c792ea
cyan | color6 | #89ddff
white | color7 | #d0d0d0
light-black | color8 | #434758
light-red | color9 | #ff8b92
light-green | color10 | #ddffa7
light-yellow | color11 | #ffe585
light-blue | color12 | #9cc4ff
light-magenta | color13 | #e1acff
light-cyan | color14 | #a3f7ff
light-white | color15 | #ffffff

The table above is the only source of truth for colors in this config.

The first way to get colors of it is to use the following noweb:

    (let ((color (seq-some (lambda (e) (and (string= name (car e)) (nth 2 e))) table)))
      (if (> quote 0)
          (concat "\"" color "\"")
        color))

Also, run the following to disable configuration for noweb evaluations:

    (setq-local org-confirm-babel-evaluate nil)

Test:

    <<get-color(name="red", quote=1)>>

### Xresources

#### Colors in Xresources

However, I’d rather use the `Xresources` file wherever possible. Here is the code to generate an Xresources file from this table:

    (apply
     #'concat
     (mapcar
      (lambda (elem)
        (concat "*" (nth 1 elem) ": " (nth 2 elem) "\n"))
      (seq-filter
       (lambda (elem) (nth 1 elem))
       table)))

    <<get-xresources()>>

    *background: <<get-color(name="black")>>
    *foreground: <<get-color(name="white")>>

#### Fonts

Also, Xresources are used to set `Xft` settings. Unfortunately, the DPI setting has to be unique for each machine, which means I cannot commit `Xresources` to the repo.

    (let ((hostname (system-name)))
      (cond ((string-equal hostname "azure") 120)
    	((string-equal hostname "eminence") 120)
    	((string-equal hostname "indigo") 120)
    	(t 96)))

    Xft.dpi: <<get-dpi()>>

### Themes

A few programs I use to customize the apperance are listed below.

Guix dependency | Description
--- | ---
matcha-theme | My preferred GTK theme
papirus-icon-theme | My preferred Icon theme
xsettingsd | X11 settings daemon

xsettingsd is a lightweight daemon which configures X11 applications. It is launched with shepherd in the Services section.

    Net/ThemeName "Matcha-dark-azul"
    Net/IconThemeName "Papirus-Dark"
    Gtk/DecorationLayout "menu:minimize,maximize,close"
    Gtk/FontName "Sans 10"
    Gtk/MonospaceFontName "JetBrainsMono Nerd Mono 12"
    Gtk/CursorThemeName "Adwaita"
    Xft/Antialias 1
    Xft/Hinting 0
    Xft/HintStyle "hintnone"

### Device-specific settings

Guix dependency | Description
--- | ---
xrandr | X11 CLI to RandR
xgamma | A tool to alter monitor’s gamma correction
xinput | Configure input devices

Set screen layout & other params depending on hostname

    hostname=$(hostname)
    if [ "$hostname" = "indigo" ]; then
        xrandr --output DisplayPort-0 --off --output HDMI-A-0 --mode 1920x1080 --pos 0x0 --rotate normal --output DVI-D-0 --mode 1920x1080 --pos 1920x0 --rotate normal
    elif [ "$hostname" = "eminence" ]; then
        xgamma -gamma 1.25
    fi

## i3wm

Guix dependency | Disabled
--- | ---
i3-gaps |
i3lock | true

`i3lock` is disabled because the global one has to be used.

i3wm is a manual tiling window manager, which is currently my window manager of choice. I’ve tried several alternatives, including xmonad & EXWM, but i3 seems to fit my workflow best.

i3-gaps is an i3 fork with a few features like window gaps. I like to enable inner gaps when there is at least one container in a workspace.

    # Cycle workspaces
    bindsym $mod+comma workspace prev
    bindsym $mod+period workspace next

### Rules

Rules to automatically assign applications to workspaces and do other stuff, like enable floating.

Most apps can be distinguished by a WM class (you can get one with xprop), but in some cases it doesn’t work, e.g. for terminal applications. In that case rules can be based on a window title, for instance.

However, watch out for the following: rule such as `for_window [title="ncmpcpp.*"] move to workspace $w9` will move any window with a title starting with `ncmpcpp` to workspace `$w9`. For instance, it moves your browser when you google “ncmpcpp”.

    assign [class="Emacs"] $w1
    assign [class="qutebrowser"] $w2
    assign [class="firefox"] $w2
    assign [class="VK"] $w3
    assign [class="Slack"] $w3
    assign [class="discord"] $w3
    assign [class="TelegramDesktop"] $w3
    assign [class="Postman"] $w4
    assign [class="Chromium-browse"] $w4
    assign [class="chromium"] $w4
    assign [class="google-chrome"] $w4
    assign [title="Vue Developer Tools"] $w4
    assign [class="Google Play Music Desktop Player"] $w9
    assign [class="jetbrains-datagrip"] $w4
    assign [class="zoom"] $w7
    assign [class="skype"] $w7
    assign [class="Mailspring"] $w8
    assign [class="Thunderbird"] $w8
    assign [class="Joplin"] $w8
    assign [class="keepassxc"] $w10

    for_window [title="VirtScreen"] floating enable

    for_window [title="ncmpcpp.*"] move to workspace $w9
    for_window [title="newsboat.*"] move to workspace $w9
    for_window [title=".*run_wego"] move to workspace $w9
    for_window [class="cinnamon-settings*"] floating enable
    for_window [title="Picture-in-Picture"] sticky enable
    for_window [window_role="GtkFileChooserDialog"] resize set width 1000 px height 800 px
    for_window [window_role="GtkFileChooserDialog"] move position center

### Scratchpad

Scratch terminal, inspired by this Luke Smith’s video.

#### Launch script

First of all, we have to distinguish a scratchpad terminal from a normal one. To do that, one can create st with a required classname.

Then, it would be cool not to duplicate scratchpads, so the following script first looks for a window with a created classname. If it exists, the script just toggles the scratchpad visibility. Otherwise, a new instance of a window is created.

    CLASSNAME="dropdown_tmux"
    COMMAND="alacritty --class $CLASSNAME -e tmux new-session -s $CLASSNAME"
    pid=$(xdotool search --classname "dropdown_tmux")
    if [[ ! -z $pid  ]]; then
        i3-msg scratchpad show
    else
        setsid -f ${COMMAND}
    fi

#### i3 config

    # Scratchpad
    for_window [instance="dropdown_*"] floating enable
    for_window [instance="dropdown_*"] move scratchpad
    for_window [instance="dropdown_*"] sticky enable
    for_window [instance="dropdown_*"] scratchpad show
    for_window [instance="dropdown_*"] move position center

    bindsym $mod+u exec ~/bin/scripts/dropdown

### Gaps & borders

The main reason to use i3-gaps

    # Borders
    # for_window [class=".*"] border pixel 0
    default_border pixel 3
    hide_edge_borders both

    # Gaps
    set $default_inner 10
    set $default_outer 0

    gaps inner $default_inner
    gaps outer $default_outer

    smart_gaps on

#### Keybindings

    mode "inner gaps" {
        bindsym plus gaps inner current plus 5
        bindsym minus gaps inner current minus 5
        bindsym Shift+plus gaps inner all plus 5
        bindsym Shift+minus gaps inner all minus 5
        bindsym 0 gaps inner current set 0
        bindsym Shift+0 gaps inner all set 0

        bindsym r gaps inner current set $default_inner
        bindsym Shift+r gaps inner all set $default_inner

        bindsym Return mode "default"
        bindsym Escape mode "default"
    }

    mode "outer gaps" {
        bindsym plus gaps outer current plus 5
        bindsym minus gaps outer current minus 5
        bindsym Shift+plus gaps outer all plus 5
        bindsym Shift+minus gaps outer all minus 5
        bindsym 0 gaps outer current set 0
        bindsym Shift+0 gaps outer all set 0

        bindsym r gaps outer current set $default_outer
        bindsym Shift+r gaps outer all set $default_outer

        bindsym Return mode "default"
        bindsym Escape mode "default"
    }

    bindsym $mod+g mode "inner gaps"
    bindsym $mod+Shift+g mode "outer gaps"

### Move & resize windows

A more or less standard set of keybindings to move & resize floating windows.

Just be careful to always make a way to return from these new modes, otherwise, you’d end up in a rather precarious position.

    # resize window (you can also use the mouse for that)
    mode "resize" {
        # These bindings trigger as soon as you enter the resize mode

        bindsym h resize shrink width 10 px or 10 ppt
        bindsym j resize grow height 10 px or 10 ppt
        bindsym k resize shrink height 10 px or 10 ppt
        bindsym l resize grow width 10 px or 10 ppt

        bindsym Shift+h resize shrink width 100 px or 100 ppt
        bindsym Shift+j resize grow height 100 px or 100 ppt
        bindsym Shift+k resize shrink height 100 px or 100 ppt
        bindsym Shift+l resize grow width 100 px or 100 ppt

        # same bindings, but for the arrow keys
        bindsym Left resize shrink width 10 px or 10 ppt
        bindsym Down resize grow height 10 px or 10 ppt
        bindsym Up resize shrink height 10 px or 10 ppt
        bindsym Right resize grow width 10 px or 10 ppt

        bindsym Shift+Left resize shrink width 100 px or 100 ppt
        bindsym Shift+Down resize grow height 100 px or 100 ppt
        bindsym Shift+Up resize shrink height 100 px or 100 ppt
        bindsym Shift+Right resize grow width 100 px or 100 ppt

        # back to normal: Enter or Escape
        bindsym Return mode "default"
        bindsym Escape mode "default"
    }

    bindsym $mod+r mode "resize"

    mode "move" {
        bindsym $mod+Tab focus right

        bindsym Left  move left
        bindsym Down  move down
        bindsym Up    move up
        bindsym Right move right

        bindsym h     move left
        bindsym j     move down
        bindsym k     move up
        bindsym l     move right

        # back to normal: Enter or Escape
        bindsym Return mode "default"
        bindsym Escape mode "default"
    }

    bindsym $mod+m mode "move" focus floating

### OFF (OFF) Intergration with dmenu

dmenu is a dynamic menu program for X. I’ve opted out of using it in favour of rofi, but here is a relevant bit of config.

Scripts are located in the `bin/scripts` folder.

    # dmenu
    bindsym $mod+d exec i3-dmenu-desktop --dmenu="dmenu -l 10"
    bindsym $mod+apostrophe mode "dmenu"

    mode "dmenu" {
        bindsym d exec i3-dmenu-desktop --dmenu="dmenu -l 10"; mode default
        bindsym p exec dmenu_run -l 10; mode default
        bindsym m exec dmenu-man; mode default
        bindsym b exec dmenu-buku; mode default
        bindsym f exec dmenu-explore; mode default
        bindsym t exec dmenu-tmuxp; mode default
        bindsym Escape mode "default"
    }

    bindsym $mod+b exec --no-startup-id dmenu-buku

### Integration with rofi

Keybindings to launch rofi. For more detail, look the Rofi section.

    bindsym $mod+d exec "rofi -modi 'drun,run' -show drun"
    bindsym $mod+b exec --no-startup-id rofi-buku-mine

    bindsym $mod+apostrophe mode "rofi"

    mode "rofi" {
        bindsym d exec "rofi -modi 'drun,run' -show drun"
        bindsym m exec rofi-man; mode default
        bindsym b exec rofi-buku-mine; mode default
        bindsym k exec rofi-keepassxc -d ~/MEGAsync/Passwords.kdbx; mode default
        bindsym Escape mode "default"
    }

### Launching apps & misc keybindings

I prefer to use a separate mode to launch most of my apps, with some exceptions.

#### Apps

    # Launch apps
    # start a terminal at workspace 1
    bindsym $mod+Return exec "i3-msg 'workspace 1 🚀; exec alacritty'"

    bindsym $mod+p exec "copyq menu"
    bindsym $mod+Shift+x exec "i3lock -f -i /home/pavel/Pictures/lock-wallpaper.png"

    bindsym $mod+semicolon mode "apps"

    mode "apps" {
        bindsym Escape mode "default"
        bindsym b exec firefox; mode default
        bindsym v exec vk; mode default
        bindsym s exec slack-wrapper; mode default;
        bindsym d exec "flatpak run com.discordapp.Discord"; mode default;
        bindsym m exec "alacritty -e ncmpcpp"; mode default
        bindsym c exec "copyq toggle"; mode default
        bindsym k exec "keepassxc"; mode default
        # bindsym e exec mailspring; mode default
        bindsym a exec emacs; mode default
        bindsym n exec "alacritty -e newsboat"; mode default
        bindsym w exec "alacritty /home/pavel/bin/scripts/run_wego"; mode default
        # bindsym a exec emacsclient -c; mode default
        # bindsym Shift+a exec emacs; mode default
    }

#### Media controls & brightness

    # Pulse Audio controls
    bindsym XF86AudioRaiseVolume exec --no-startup-id "ponymix increase 5 --max-volume 150"
    bindsym XF86AudioLowerVolume exec --no-startup-id "ponymix decrease 5 --max-volume 150"
    bindsym XF86AudioMute exec --no-startup-id "ponymix toggle"

    exec --no-startup-id xmodmap -e 'keycode 135 = Super_R' && xset -r 135
    bindsym $mod+F2 exec --no-startup-id "ponymix increase 5"
    bindsym $mod+F3 exec --no-startup-id "ponymix decrease 5"

    # Media player controls
    bindsym XF86AudioPlay exec mpc toggle
    bindsym XF86AudioPause exec mpc pause
    bindsym XF86AudioNext exec mpc next
    bindsym XF86AudioPrev exec mpc prev

    # Screen brightness
    bindsym XF86MonBrightnessUp exec light -A 5
    bindsym XF86MonBrightnessDown exec light -U 5

#### Screenshots

    # Screenshots
    bindsym --release Print exec "flameshot gui"
    bindsym --release Shift+Print exec "xfce4-screenshooter"

### Colors

Application of the XResources theme to the WM.

    exec xrdb -merge $HOME/.Xresources

    # Colors
    set_from_resource $bg-color            background
    set_from_resource $active-color        color4
    set_from_resource $inactive-bg-color   color8
    set_from_resource $text-color          foreground
    set_from_resource $inactive-text-color color7
    set_from_resource $urgent-bg-color     color1
    set_from_resource $urgent-text-color   color0

    # window colors
    #                       border              background         text                 indicator       child border
    client.focused          $active-color       $bg-color          $text-color          $bg-color       $active-color
    client.unfocused        $bg-color           $inactive-bg-color $inactive-text-color $bg-color       $bg-color
    client.focused_inactive $active-color       $inactive-bg-color $inactive-text-color $bg-color       $bg-color
    client.urgent           $urgent-bg-color    $urgent-bg-color   $urgent-text-color   $bg-color       $urgent-bg-color

### OFF (OFF) i3blocks

I’ve opted out of i3bar & i3blocks for polybar

    bar {
        status_command i3blocks -c ~/.config/i3/i3blocks.conf
        i3bar_command i3bar
        font pango:monospace 12
        output HDMI-A-0
        tray_output none
        colors {
    	background $bg-color
    	separator #757575
    	#                  border             background         text
    	focused_workspace  $bg-color          $bg-color          $text-color
    	inactive_workspace $inactive-bg-color $inactive-bg-color $inactive-text-color
    	urgent_workspace   $urgent-bg-color   $urgent-bg-color   $urgent-text-color
        }
    }

    bar {
        status_command i3blocks -c ~/.config/i3/i3blocks.conf
        i3bar_command i3bar
        font pango:monospace 10
        output DVI-D-0
        colors {
    	background $bg-color
    	separator #757575
    	#                  border             background         text
    	focused_workspace  $bg-color          $bg-color          $text-color
    	inactive_workspace $inactive-bg-color $inactive-bg-color $inactive-text-color
    	urgent_workspace   $urgent-bg-color   $urgent-bg-color   $urgent-text-color
        }
    }

### Keyboard Layout

A script to set Russian-English keyboard layout:

    setxkbmap -layout us,ru
    setxkbmap -model pc105 -option 'grp:win_space_toggle' -option 'grp:alt_shift_toggle'

A script to toggle the layout

    if setxkbmap -query | grep -q us,ru; then
        setxkbmap -layout us
        setxkbmap -option
    else
        setxkbmap -layout us,ru
        setxkbmap -model pc105 -option 'grp:win_space_toggle' -option 'grp:alt_shift_toggle'
    fi

And the relevant i3 settings:

    # Layout
    exec_always --no-startup-id set_layout
    bindsym $mod+slash exec toggle_layout

### Autostart

    # Polybar
    exec_always --no-startup-id "bash /home/pavel/bin/polybar.sh"

    # Wallpaper
    exec_always "feh --bg-fill ~/Pictures/wallpaper.jpg"

    # Picom
    exec picom

    # Keynav
    exec keynav

    # Applets
    exec --no-startup-id nm-applet
    # exec --no-startup-id /usr/bin/blueman-applet

    exec shepherd
    exec dunst
    exec copyq
    exec "xmodmap ~/.Xmodmap"
    # exec "xrdb -merge ~/.Xresources"
    # exec "bash ~/bin/autostart.sh"

polybar | statusbar

Polybar is a nice-looking, WM-agnostic statusbar program.

I switched to polybar because I wanted to try out some WMs other than i3, but decided to stick with i3 for now.

Don’t forget to install the Google Noto Color Emoji font. Guix package with all Noto fonts is way too large.

### Launching

The script below allows me to:

- have different blocks on my two different-sized monitors and my laptop;
- have different settings on my desktop PC and laptop;

    hostname=$(hostname)
    # Settings varying on the hostname
    export WLAN_INTERFACE=$(nmcli -f DEVICE con show | grep -Ev "(.*docker.*|DEVICE|br.*|tun.*|veth.*|--)" | xargs)
    if [ "$hostname" = "azure" ]; then
        TRAY_MONITOR="eDP-1"
        # export WLAN_INTERFACE="wlp3s0"
    elif [ "$hostname" = "eminence" ]; then
        TRAY_MONITOR="eDP"

### Modules

Some of the custom modules below use Org mode noweb to evaluate colors, because it’s faster than querying `xrdb` at runtime. I wish I could reference polybar values there, but it looks like this is impossible.

If you want to copy something, you can go to the bin/polybar folder.

#### ipstack-vpn

Guix dependency | Description
--- | ---
bind:utils | Provides dig

### Scripts

#### Buku bookmarks

Inspired by the knatsakis/rofi-buku script.

    if [ $(hostname) = 'pdsk' ]; then
        BUKU="/home/pavel/.local/bin/buku"
    else
        BUKU="/home/pavel/Programs/miniconda3/bin/buku"
    fi

    # COMMAND="$BUKU -o %"
    # COMMAND="qutebrowser $(buku -f 10 -p %)"
    COMMAND="firefox %"
    if [[ $1 == '-e' ]]; then
        COMMAND="$BUKU -w %"
    fi
    $BUKU -f 4 -p | awk -F'\t' -v OFS='\t' '{
        split($4, tags, ",")
        joined = sep = ""
        for (i = 1; i in tags; i++) {
    	joined = joined sep "[" tags[i] "]"
    	sep = " "
        }
        url = substr($2, 1, 40)
        if (length($2) > 40) {
    	url = url "..."
        }
        if ($1 != "waiting for input") {
    	printf "%-5s %-60s %-45s %s\n", $1, $3, url, joined
        }
    }' | sort -k 2 | rofi -dmenu -matching normal -sort -sorting-method fzf -width 80 -l 20 | cut -d ' ' -f 1 | {
        read index;
        if [[ -z "$index" ]]; then
    	exit 0
        fi
        url=$($BUKU -f 10 -p $index)
        echo ${url#"waiting for input"} | cut -d ' ' -f 1 | xargs -I % $COMMAND
    }

#### Man pages

Inspired by this Luke Smith’s video.

A script to open a man page with zathura. There is no particular reason why one should look through man pages in pdf viewer rather than in console, but why not.

    SELECTED=$(man -k . | rofi -dmenu -l 20 | awk '{print $1}')
    if [[ ! -z $SELECTED ]]; then
        man -Tpdf $SELECTED | zathura -

SYMLINK | ./config/keynavrc -> .keynavrc

How many times you have been working with keyboard-driven programs and had to use a mouse just to press some pesky little button in a modal window?

keynav is a program that allows you to control the mouse with the keyboard with the general idea of bisecting the screen to get to the required point. I’m still not sure if there is any point in using it, but it’s rather funny. Unfortunately, the colors seem to be hardcoded.

One of the usecases I found so far is to use the program to scroll webpages when tridactyl’s scroll captures the wrong scroll area.

### Using with picom

I’ve noticed that the program does not play nice with picom’s fade effect. To fix that, add the following to you config:

    fade-exclude = [
      "class_i = 'keynav'",
      "class_g = 'keynav'",
    ]

## Picom

Guix dependency
picom

picom is a compositor for X11. It allows effects such as transparency, blurring, etc.

Sample configuration is a good resource for getting an overview of the available settings. I have only a bunch of necessary settings in mine.

There are a bunch of forks for picom (e.g. ibhagwan/picom adds rounded corners) which seem to have some popularity, but I use the base one.

### Shadows

    shadow = true;
    shadow-radius = 2;
    shadow-offset-x = -2;
    shadow-offset-y = -2;

    shadow-exclude = [
      "name = 'Notification'",
      "class_g = 'Conky'",
      "name ?= 'cpt_frame_window'",
      "class_g ?= 'Notify-osd'",
      "class_g = 'Cairo-clock'",
      "_GTK_FRAME_EXTENTS@:c"
    ];

### Fading

    fading = true

    fade-in-step = 0.03;
    fade-out-step = 0.03;
    fade-delta = 10

    fade-exclude = [
      "class_i = 'keynav'",
      "class_g = 'keynav'",
    ]

### Opacity

I don’t use stuff like transparency for inactive windows.

The first 5 lines of `opacity-rule` make i3wm’s hidden windows 100% transparent, so I see the background behind the semi-transparent windows in i3wm’s stacked and tabbed layout. Here is StackExchange question about that.

I also noticed that for some reason it doesn’t play well with Emacs’s built-in transparency, so the last line sets up Emacs transparency at 90%.

    inactive-opacity = 1;

    frame-opacity = 1.0;
    inactive-opacity-override = false;
    focus-exclude = [ "class_g = 'Cairo-clock'" ];

    opacity-rule = [
      "0:_NET_WM_STATE@[0]:32a = '_NET_WM_STATE_HIDDEN'",
      "0:_NET_WM_STATE@[1]:32a = '_NET_WM_STATE_HIDDEN'",
      "0:_NET_WM_STATE@[2]:32a = '_NET_WM_STATE_HIDDEN'",
      "0:_NET_WM_STATE@[3]:32a = '_NET_WM_STATE_HIDDEN'",
      "0:_NET_WM_STATE@[4]:32a = '_NET_WM_STATE_HIDDEN'",
      "90:class_g = 'Emacs'"

## Zathura

Guix dependency
zathura
zathura-ps
zathura-pdf-poppler
zathura-djvu

Zathura is a pdf viewer with vim-like keybindings. One of my favorite features is an ability to invert the document colors.

    set abort-clear-search false
    set show-scrollbars true
    set show-h-scrollbar true
    set show-v-scrollbar true
    set selection-clipboard clipboard
    set recolor-lightcolor <<get-color(name="black", quote=1)>>
    set recolor true
    map <C-r> set recolor false
    map <C-R> set recolor true

### Flatpak

A lot of proprietary desktop applications can be installed most easily with flatpak & flathub.

Guix dependency
flatpak
xdg-desktop-portal

After installation, add the following repositories:

    flatpak remote-add --user --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
    flatpak remote-add --user --if-not-exists flathub-beta https://flathub.org/beta-repo/flathub-beta.flatpakrepo

Installation syntax is as follows:

    flatpak install --user <remote> <package>

Packages to install:

Flatpak dependency | Channel
--- | ---
com.github.wwmm.pulseeffects | flathub
com.discordapp.Discord | flathub
us.zoom.Zoom | flathub
com.slack.Slack | flathub

    (mapconcat
     (lambda (c) (concat "flatpak install -y --user " (nth 1 c) " " (nth 0 c)))
     table
     "\n")

### Nix

Type | Description
--- | ---
TODO | Make nix manifest?

I probably should’ve used nix, as almost every program I packaged so far exists in the Nix repo.

But it’s easy enough to use Nix on Guix.

    https://nixos.org/channels/nixpkgs-unstable nixpkgs

Don’t forget to run the following after the first installation:

    nix-channel --update

Installing packages:

    nix-env -i vk-messenger slack

## Services

GNU Shepherd is a service management system for GNU Guix.

I previously used supervisor, but shepherd also seems pretty capable.

### Music

Category | Guix dependency
--- | ---
music | mpd
music | ncmpcpp
music | picard
music | mpd-watcher
music | mpd-mpc
music | shntool
music | cuetools
music | flac

Music player daemon

    (define mpd
      (make <service>
        #:provides '(mpd)
        #:respawn? #t
        #:start (make-forkexec-constructor '("mpd" "--no-daemon"))
        #:stop (make-kill-destructor)))

MPD watcher

    (define mpd-watcher
      (make <service>
        #:provides '(mpd-watcher)
        #:respawn? #t
        #:start (make-forkexec-constructor '("mpd_watcher"))
        #:stop (make-kill-destructor)
        #:requires '(mpd)))

### GNU Mcron

GNU Mcron is a replacement for cron, written in Scheme.

    (define mcron
      (make <service>
        #:provides '(mcron)
        #:respawn? #t
        #:start (make-forkexec-constructor '("mcron"))
        #:stop (make-kill-destructor)))

### ActivityWatch

ActivityWatch is a FOSS time tracker. It tracks screen and application usage and has integrations with browsers, Emacs, etc.

Guix dependency
activitywatch-bin

aw-server

    (define aw-server
      (make <service>
        #:provides '(aw-server)
        #:respawn? #t
        #:start (make-forkexec-constructor '("aw-server"))
        #:stop (make-kill-destructor)))

`aw-watcher-afk` has some problems with statup, so there is a wrapper script

    sleep 5
    aw-watcher-afk

aw-watcher-afk

    (define aw-watcher-afk
      (make <service>
        #:provides '(aw-watcher-afk)
        #:requires '(aw-server)
        #:respawn? #t
        #:start (make-forkexec-constructor '("/home/pavel/bin/scripts/aw-watcher-afk-wrapper"))
        #:stop (make-kill-destructor)))

aw-watcher-window

    (define aw-watcher-window
      (make <service>
        #:provides '(aw-watcher-window)
        #:requires '(aw-server)
        #:respawn? #t
        #:start (make-forkexec-constructor '("aw-watcher-window"))
        #:stop (make-kill-destructor)))

### PulseEffects

    (define pulseeffects
      (make <service>
        #:provides '(pulseeffects)
        #:respawn? #t
        #:start (make-forkexec-constructor '("flatpak" "run" "com.github.wwmm.pulseeffects" "--gapplication-service"))
        #:stop (make-kill-destructor)))

### xsettingsd

    (define xsettingsd
      (make <service>
        #:provides '(xsettingsd)
        #:respawn? #t
        #:start (make-forkexec-constructor '("xsettingsd"))
        #:stop (make-kill-destructor)))

### Discord rich presence

References:

- Rich Precense (discord rpc)

    (define discord-rich-presence
      (make <service>
        #:provides '(discord-rich-presence)
        #:one-shot? #t
        #:start (make-system-constructor "ln -sf {app/com.discordapp.Discord,$XDG_RUNTIME_DIR}/discord-ipc-0")))

### Polkit Authentication agent

Launch an authentication agent. Necessary for stuff like `pkexec`. I suspect I’m not doing that the intended way, but it seems to work.

    (define polkit-gnome
      (make <service>
        #:provides '(polkit-gnome)
        #:respawn? #t
        #:start (make-forkexec-constructor '("/home/pavel/.guix-extra-profiles/desktop/desktop/libexec/polkit-gnome-authentication-agent-1"))
        #:stop (make-kill-destructor)))

### Xmodmap

    (define xmodmap
      (make <service>
        #:provides '(xmodmap)
        #:one-shot? #t
        #:start (make-system-constructor "xmodmap /home/pavel/.Xmodmap")))

### VPN

Run my OpenVPN setup. Not lauching this automatially, as it requires an active connection.

    (define vpn
      (make <service>
        #:provides '(vpn)
        #:respawn? #t
        #:start (make-forkexec-constructor '("/home/pavel/bin/scripts/vpn-start"))
        #:stop (make-kill-destructor)))

### Davmail

    (define davmail
      (make <service>
        #:provides '(davmail)
        #:respawn? #t
        #:start (make-forkexec-constructor '("/home/pavel/bin/davmail"))
        #:stop (make-kill-destructor)))

### Shepherd config

Register services

    (register-services
     mpd
     mpd-watcher
     mcron
     aw-server
     aw-watcher-afk
     aw-watcher-window
     pulseeffects
     xsettingsd
     discord-rich-presence
     polkit-gnome
     vpn
     davmail
     xmodmap)

Daemonize shepherd

    (action 'shepherd 'daemonize)

Run services

    (for-each start '(mpd mpd-watcher mcron aw-server aw-watcher-afk aw-watcher-window pulseeffects xsettingsd discord-rich-presence polkit-gnome davmail xmodmap))
