My general desktop environment configuration.

Parts prefexed with [OFF] are not used, but kept for historic purposes. For some reason GitHub's org renderer ignores TODO status, hence such a prefix.

Most of the colors are from the Palenight theme. Colorcodes are taken from [[https://github.com/JonathanSpeek/palenight-iterm2][this repo]]:

[[https://i3wm.org/][i3wm]] is a manual tiling window manager, which is currently my window manager of choice. I've tried several alternatives, including [[https://xmonad.org/][xmonad]] & [[https://github.com/ch11ng/exwm][EXWM]], but i3 seems to fit my workflow best.

[[https://github.com/Airblader/i3][i3-gaps]] is a 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.

** 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 [[https://www.x.org/releases/X11R7.5/doc/man/man1/xprop.1.html][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 $w9~ will move *any* windows with a title, starting with =ncmpcpp= to workspace =$w9=, which, for instance, may move your browser there if you google "ncmpcpp".

#+begin_src conf-space

** Scratchpad
Scratch terminal, inspired by [[https://www.youtube.com/watch?v=q-l7DnDbiiU][this Luke Smith's video]].
*** Launch script
First of all, we have to distinguish 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 visibilty. Otherwise, a new instance of a window is created.
#+begin_src bash :tangle ./bin/scripts/dropdown
#!/bin/bash
CLASSNAME="dropdown_tmux"
COMMAND="st -n $CLASSNAME -e tmux new-session -s $CLASSNAME"
pid=$(xdotool search --classname "dropdown_tmux")
if [[ ! -z $pid  ]]; then
    i3-msg scratchpad show
else

** Move & resize windows
