* Polybar Configuration
:PROPERTIES:
:ID:       2df7b3fd-be4c-4d75-9d6b-e64e7828169a
:END:
This document outlines the configuration for Polybar, a lightweight status bar. It's written using
Org-mode's literate programming features, allowing for documentation alongside the code. The
configuration is automatically tangled into the =config= file required by Polybar upon saving this Org
file, thanks to the =#+auto_tangle: t= property and a corresponding Emacs setup (detailed at the end).

** Header
:PROPERTIES:
:ID:       575b523c-955f-4d67-8512-f1b527d39d11
:END:
This section adds an ASCII art header comment to the top of the tangled =config= file for
personalization. It doesn't affect Polybar's functionality.

:PROPERTIES:
:ID:       fbd62c62-acfb-48ea-808f-66a37417e420
:END:
Configures the main properties of the bar itself. This includes its dimensions, position (tied to the
`MONITOR` environment variable), appearance (background, foreground, over/underline styles), padding,
margins, and the fonts used. It also defines the order and placement of modules in the left, center, and
right sections of the bar.

:PROPERTIES:
:ID:       2e3d5e88-0ebb-4074-a406-b489baf141a8
:END:
Displays i3 window manager workspaces and mode information. It uses icons (from `font-1` and `font-0`) to
represent different workspace states (focused, unfocused, visible, urgent) and applies specific colors
and underlines for clarity. `pin-workspaces = true` ensures workspaces are always shown even if empty on
other monitors (if applicable).

:PROPERTIES:
:ID:       1244d450-9c41-49b0-9c27-3ebdc31f02de
:END:
Shows the current CPU utilization percentage. Updates frequently (every 0.5 seconds) and uses a '🎛'
prefix (likely from `font-5`, Noto Color Emoji). The value is underlined with the highlight color. A
warning state is triggered if usage exceeds 95%, although no specific format change is defined for the
warning state here.
#+begin_src conf

:PROPERTIES:
:ID:       02bea2d6-482c-4f97-b0fe-a1bb4462080c
:END:
Displays the percentage of RAM currently in use. Updates every 3 seconds and uses a '📊' prefix (likely
from `font-5`). The value is underlined with the accent color. A warning state is triggered if usage
exceeds 90%.
#+begin_src conf
[module/memory]
type = internal/memory
interval = 3
warn-percentage = 90
format-prefix = " 📊 "
format-underline = ${colors.accent}

** Network Module
:PROPERTIES:
:ID:       4d75cc95-a5d3-4ac3-83d6-132bfbd2883f
:END:
Monitors the status of the specified wireless network interface (`wlp0s20f3`). Shows the SSID and network
speed (padded to 9 characters) when connected (📶) and a 'not connected' message (🚫) when disconnected.
Includes a blinking animation (⚠/📶) to indicate packet loss.
#+begin_src conf
[module/wireless-network]
type = internal/network

** Clock Module
:PROPERTIES:
:ID:       b9bc5f2f-60cd-4af1-a7d8-ae08c14fe0db
:END:
Displays the current date and time. Updates every 5 seconds. The format includes day, month, year, hour,
and minute (e.g., 📅 DD-MM-YYYY 🕜 HH:MM). The `%{O4}` adds a 4-pixel right offset for spacing. Icons
likely come from `font-5`.
#+begin_src conf
[module/clock]
type = internal/date
interval = 5
date = 📅 %d-%m-%Y 🕜 %H:%M%
format = <label>   %{O4}
#+end_src

** Battery Module
:PROPERTIES:
:ID:       1bab6a07-301c-4635-acc2-23e111d0923a
:END:
Shows the current battery status for `BAT0` and adapter `AC`. Uses different icons (🔌/🔋 from `font-3`,
Siji) and labels depending on whether the battery is charging, discharging, or full (defined as 99% or
higher). The percentage labels use `font-2` (Termsynu).
#+begin_src conf
[module/battery]
type = internal/battery
full-at = 99
battery = BAT0
adapter = AC
format-charging = %{T3} 🔌 <label-charging> %{T-}

** Window Module
:PROPERTIES:
:ID:       1a97f59b-6f5c-4178-9724-4db491147799
:END:
Displays the title of the currently active window (`xwindow`). The title is truncated to a maximum of 50
characters (`label-maxlen`) to prevent it from taking up too much space on the bar.
#+begin_src conf
[module/xwindow]
type = internal/xwindow
label-maxlen = 50
label-foreground = ${colors.foreground}
#+end_src

** Keyboard Module
:PROPERTIES:
:ID:       33605481-48d4-40e9-8a94-22b5a18836e0
:END:
Shows the current keyboard layout by executing a custom script (`keyboard_lang.sh`). The script's output
is displayed in the bar. Updates every second. This approach is often used when the built-in
`internal/xkeyboard` module doesn't meet specific needs.
#+begin_src conf
[module/xkeyboard]
type = custom/script
exec = /home/roger/.config/polybar/keyboard_lang.sh
interval = 1
#+end_src

** Audio Module
:PROPERTIES:
:ID:       336131a7-466d-435d-aa5d-fd2647185cb9
:END:
Displays the current PulseAudio volume level (using the 🔊 icon, likely from `font-5`) or a muted icon
(🔈) if the audio is muted. The muted icon uses the `dimmed` color. Updates every second.
#+begin_src conf
[module/pulseaudio]
type = internal/pulseaudio
label-volume = 🔊 %percentage%%
label-muted = 🔈
label-muted-foreground = ${colors.muted}
interval = 1
#+end_src

** Spotify Module
:PROPERTIES:
:ID:       8df357e0-6463-4d62-9ed1-cb3319fcfaa0
:END:
Displays the current Spotify status (play/pause state, song title, artist, album) using a custom Python
script (`spotify_status.py`). Updates every second. The script arguments control text truncation length
(`-t 80`), the font used for play/pause icons (`--playpause-font=1`), the specific icons for play/pause
states (`-p '⏯,⏸️'`), and the overall output format (`-f`).
#+begin_src conf
[module/spotify]
type = custom/script
interval = 1
exec = python /home/roger/.config/polybar/spotify_status.py -t 80 --playpause-font=1 -p '⏯,⏸️' -f ' {play_pause} {song} - {artist} - {album}'
#+end_src

** Music Module
:PROPERTIES:
:ID:       bba107c2-b029-4062-a664-5084d8077159
:END:
Displays information from a generic music player, likely using MPRIS (Media Player Remote Interfacing
Specification), via a custom script (`~/.config/polybar/music`). The script's output is displayed
directly (`label = %output%`). Updates every second. This can work with various players like Spotify,
VLC, etc., if the script supports them.
#+begin_src conf
[module/music]
type = custom/script
interval = 1
label = %output%
exec = ~/.config/polybar/music
#+end_src

** ProtonVPN Module
:PROPERTIES:
:ID:       5423289c-0994-482b-9148-5f64c37ae4e1
:END:
Shows the connection status of ProtonVPN by executing a custom script (`protonvpn_status.sh`). The
script's output indicates whether the VPN is connected, disconnected, or in another state. Updates every
15 seconds.
#+begin_src conf
[module/protonvpn-status]
type = custom/script
exec = /home/roger/.config/polybar/protonvpn_status.sh
interval = 15
#+end_src

** Do Not Disturb Module
:PROPERTIES:
:ID:       e494ecce-e6f6-4f3d-87f7-4299012ab329
:END:
Indicates whether a 'Do Not Disturb' mode is active, likely by checking the status of a notification
daemon (like `dunst`) via a custom script (`dnd_status.sh`). The script's output presumably changes to
reflect the DND state. Updates every second.
#+begin_src conf
[module/dnd]
type = custom/script
exec = /home/roger/.config/polybar/dnd_status.sh
interval = 1
#+end_src

** CPU Temperature Module
:PROPERTIES:
:ID:       561fdf25-f9bd-41c8-b719-bd23dd501a97
:END:
Displays the CPU temperature obtained from a specific hardware monitoring path
(`/sys/devices/platform/coretemp.0/hwmon/hwmon5/temp1_input`). Updates every 0.5 seconds. Uses '🌡' as a
prefix. If the temperature exceeds the `warn-temperature` (80°C), it displays a warning format with a
fire icon (🔥).
#+begin_src conf
[module/cpu-temperature]
type = internal/temperature
interval = 0.5
thermal-zone = 0
hwmon-path = /sys/devices/platform/coretemp.0/hwmon/hwmon5/temp1_input
base-temperature = 20
warn-temperature = 80
format-prefix = "🌡"
label-warn = 🔥 %temperature-c%
#+end_src

** GPU Temperature Module
:PROPERTIES:
:ID:       85b64b44-fa61-4389-a234-f665cdbb8ac6
:END:
Displays the GPU temperature obtained from a specific hardware monitoring path
(`/sys/devices/virtual/hwmon/hwmon4/temp9_input`). Updates every 0.5 seconds. A warning state is
triggered if the temperature exceeds 80°C, although no specific warning format (like a prefix or
different label) is defined in this configuration block. The default label format (`%temperature-c%`)
will likely still be used unless overridden elsewhere or by default Polybar behavior for warnings.
#+begin_src conf
[module/gpu-temperature]
type = internal/temperature
interval = 0.5
thermal-zone = 0
hwmon-path = /sys/devices/virtual/hwmon/hwmon4/temp9_input
base-temperature = 20
warn-temperature = 80
#+end_src

** Cryptocurrency Module
:PROPERTIES:
:ID:       2a233eed-8e1d-4af1-b53f-68662498607f
:END:
Displays the price of Bitcoin (BTC) in US Dollars (USD) using a custom Python script (`pcrypto.py`). The
script is called with arguments specifying the base currency and the coin symbol. Updates every 60
seconds.
#+begin_src conf
[module/crypto]
type = custom/script
exec = python ~/.config/polybar/pcrypto.py --base USD --coins btc
interval = 60
#+end_src

* Setting Up Auto-Tangle
:PROPERTIES:
:ID:       cf0495ac-2aac-4077-829f-2d27f1385f13
:END:
This configuration file uses Org Mode's literate programming capabilities. To automatically generate the
=config= file needed by Polybar every time this =.org= file is saved in Emacs, you need to add the
following Elisp code to your Emacs initialization file (e.g., =~/.emacs.d/init.el=). This code defines a
function `org-babel-auto-tangle` and adds it to the `after-save-hook`. When an Org file is saved, this
function checks for the `#+auto_tangle: t` property at the beginning of the file and, if found, runs
`org-babel-tangle` to generate the output file(s) (in this case, =config=).

#+begin_src emacs-lisp :tangle no
