* Introduction
This is a QTile configuration meant to be a monolithic configuration of QTile along with widgets i.e. run launcher, bar, and notification panel.
This enables the window manager to be integrated with these things entirely, making for a unified experience in terms of configuration, styling,
and functionality.

This configuration imports ~WALLPAPER~ and ~SOUND~ from my [[file:./nix.org][NixOS Configuration]], and therefore if you use this standalone you must replace those variables.
* Imports
We start with imports:
#+begin_src python :tangle ../nix/qtile/config.py
from paths import WALLPAPER, SOUND
from libqtile import bar, layout, widget, qtile
from libqtile.config import Key, Group, Screen, Click, Drag, Match
from libqtile.lazy import lazy
from libqtile.backend.wayland import InputConfig
from qtile_extras.layout.decorations import RoundedCorners

import re
#+end_src
We're using wayland because it's better.
* Config
#+begin_src python :tangle ../nix/qtile/config.py
