* Global customization
** Colors
My favorite color theme is Palenight ([[https://github.com/JonathanSpeek/palenight-iterm2][color codes]]), and I want to have one source of truth for these colors. Except for Emacs itself, which has [[https://github.com/doomemacs/themes#theme-list][doom-palenight]] (and in which I occasionally switch to =doom-one-light=, e.g. when reading a long text), it can be done rather nicely with Org Mode.
First, let's define a table with all the color codes:
#+tblname: colors
| 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 |
| color-fg | | #000000 |
The table above is the only source of truth for colors in this config.
Contents of this table can then be [[https://orgmode.org/manual/Environment-of-a-Code-Block.html][accessed from a code block]]. Let's define one to return the color code based on its name:
#+NAME: get-color
#+begin_src emacs-lisp :var table=colors name="black" quote=0
(let ((color (seq-some (lambda (e) (and (string= name (car e)) (nth 2 e))) table)))
(if (> quote 0)
(concat "\"" color "\"")
color))
#+end_src
Test:
#+begin_src emacs-lisp :noweb yes
<<get-color(name="red", quote=1)>>
#+end_src
#+RESULTS:
: #f07178
** 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:
#+NAME: get-xresources
#+begin_src emacs-lisp :var table=colors
(mapconcat
(lambda (elem)
(concat "*" (nth 1 elem) ": " (nth 2 elem)))
(seq-filter
(lambda (elem) (and (nth 1 elem)
(not (string-empty-p (nth 1 elem)))))
table)
"\n")
#+end_src
#+begin_src conf-xdefaults :noweb yes :tangle ~/.Xresources
<<get-xresources()>>
*background: <<get-color(name="black")>>
*foreground: <<get-color(name="white")>>
#+end_src
So, whenever a program is capable of reading =.Xresources=, it will get colors from there, otherwise, it will get colors from noweb expressions in the literate config. Thus, in both cases, the color is set in a single Org Mode table.
*** 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.
#+NAME: get-dpi
#+begin_src emacs-lisp
(let ((hostname (system-name)))
(cond ((string-equal hostname "azure") 120)
((string-equal hostname "eminence") 120)
((string-equal hostname "indigo") 120)
(t 96)))
#+end_src
#+begin_src conf-xdefaults :noweb yes :tangle ~/.Xresources
Xft.dpi: <<get-dpi()>>
#+end_src

** Startup & UI
*** Xsession
First things first, Emacs has to be launched as a window manager. On a more conventional system I'd create a .desktop file in some system folder that can be seen by a login manager, but in the case of Guix it's a bit more complicated, because all such folders are not meant to be changed manually.
| Category | Guix dependency |
|--------------+-----------------|
| desktop-misc | xinit |
| desktop-misc | xss-lock |
However, GDM, the login manager that seems to be the default on Guix, launches =~/.xsession= on the startup if it's present, which is just fine for my purposes.
#+begin_src sh :tangle ~/.xsession
# Source .profile
. ~/.profile
# Disable access control for the current user
xhost +SI:localuser:$USER
# Fix for Java applications
export _JAVA_AWT_WM_NONREPARENTING=1
# Apply XResourses
xrdb -merge ~/.Xresources
# Turn off the system bell
xset -b
# Use i3lock as a screen locker
xss-lock -- i3lock -f -i /home/pavel/Pictures/lock-wallpaper.png &
# Some apps that have to be launched only once.
picom &
# nm-applet &
dunst &
copyq &
# Run the Emacs startup script as a session.
# exec dbus-launch --exit-with-session ~/.emacs.d/run-exwm.sh
exec dbus-launch --exit-with-session emacs -mm --debug-init -l ~/.emacs.d/desktop.el
#+end_src
*** Startup apps
Now that Emacs is launched, it is necessary to set up the EXWM-specific parts of config.
I want to launch some apps from EXWM instead of the Xsession file for two purposes:
- the app may need to have the entire desktop environment set up
- or it may need to be restarted if Emacs is killed.
As of now, these are polybar, feh and, shepherd:
#+begin_src emacs-lisp
(defun my/exwm-run-polybar ()
(call-process "~/bin/polybar.sh"))
(defun my/exwm-set-wallpaper ()
(call-process-shell-command "feh --bg-fill ~/Pictures/wallpaper.jpg"))
(defun my/exwm-run-shepherd ()
(when (string-empty-p (shell-command-to-string "pgrep -u pavel shepherd"))
(call-process "shepherd")))
#+end_src
*** Pinentry
The GUI pinentry doesn't work too well with EXWM because of issues with popup windows, so we will use the Emacs one.
#+begin_src emacs-lisp
(use-package pinentry
:straight t
:after (exwm)
:config
(setenv "GPG_AGENT_INFO" nil) ;; use emacs pinentry
(setq auth-source-debug t)
(setq epg-gpg-program "gpg2") ;; not necessary
(require 'epa-file)
(epa-file-enable)
(setq epa-pinentry-mode 'loopback)
(setq epg-pinentry-mode 'loopback)
(pinentry-start))
#+end_src
#+begin_src conf-space :tangle ~/.gnupg/gpg-agent.conf
default-cache-ttl 3600
max-cache-ttl 3600
allow-emacs-pinentry
allow-loopback-pinentry
#+end_src
*** Modeline
Show the current workspace in the modeline.
#+begin_src emacs-lisp
(use-package exwm-modeline
:straight (:host github :repo "SqrtMinusOne/exwm-modeline")
:config
(add-hook 'exwm-init-hook #'exwm-modeline-mode)
(my/use-doom-colors
(exwm-modeline-current-workspace
:foreground (doom-color 'yellow)
:weight 'bold)))
#+end_src
** Windows
A bunch of functions related to managing windows in EXWM.
*** Moving windows
As I wrote in my [[https://sqrtminusone.xyz/posts/2021-10-04-emacs-i3/][Emacs and i3]] post, I want to have a rather specific behavior when moving windows (which does resemble i3 in some way):
- if there is space in the required direction, move the Emacs window there;
- if there is no space in the required direction, but space in two orthogonal directions, move the Emacs window so that there is no more space in the orthogonal directions;
I can't say it's better or worse than the built-in functionality or one provided by evil, but I'm used to it and I think it fits better for managing a lot of windows.
So, first, we need a predicate that checks whether there is space in the given direction:
#+begin_src emacs-lisp
(defun my/exwm-direction-exists-p (dir)
"Check if there is space in the direction DIR.
Does not take the minibuffer into account."
(cl-some (lambda (dir)
(let ((win (windmove-find-other-window dir)))
(and win (not (window-minibuffer-p win)))))
(pcase dir
('width '(left right))
('height '(up down)))))
#+end_src
And a function to implement that:
#+begin_src emacs-lisp
(defun my/exwm-move-window (dir)
"Move the current window in the direction DIR."
(let ((other-window (windmove-find-other-window dir))
(other-direction (my/exwm-direction-exists-p
(pcase dir
('up 'width)
('down 'width)
('left 'height)
('right 'height)))))
(cond
((and other-window (not (window-minibuffer-p other-window)))
(window-swap-states (selected-window) other-window))
(other-direction
(evil-move-window dir)))))
#+end_src
My preferred keybindings for this part are, of course, =s-<H|J|K|L>=.
*** Resizing windows
I find this odd that there are different commands to resize tiling and floating windows. So let's define one command to perform both resizes depending on the context:
#+begin_src emacs-lisp
(setq my/exwm-resize-value 5)
(defun my/exwm-resize-window (dir kind &optional value)
"Resize the current window in the direction DIR.
DIR is either 'height or 'width, KIND is either 'shrink or
'grow. VALUE is `my/exwm-resize-value' by default.
If the window is an EXWM floating window, execute the
corresponding command from the exwm-layout group, execute the
command from the evil-window group."
(unless value
(setq value my/exwm-resize-value))
(let* ((is-exwm-floating
(and (derived-mode-p 'exwm-mode)
exwm--floating-frame))
(func (if is-exwm-floating
(intern
(concat
"exwm-layout-"
(pcase kind ('shrink "shrink") ('grow "enlarge"))
"-window"
(pcase dir ('height "") ('width "-horizontally"))))
(intern
(concat
"evil-window"
(pcase kind ('shrink "-decrease-") ('grow "-increase-"))
(symbol-name dir))))))
(when is-exwm-floating
(setq value (* 5 value)))
(funcall func value)))
#+end_src
This function will call =exwm-layout-<shrink|grow>[-horizontally]= for EXWM floating window and =evil-window-<decrease|increase>-<width|height>= otherwise.
This function can be bound to the required keybindings directly, but I prefer a hydra to emulate the i3 submode:
#+begin_src emacs-lisp
(defhydra my/exwm-resize-hydra (:color pink :hint nil :foreign-keys run)
"
^Resize^
_l_: Increase width _h_: Decrease width _j_: Increase height _k_: Decrease height
_=_: Balance "
("h" (lambda () (interactive) (my/exwm-resize-window 'width 'shrink)))
("j" (lambda () (interactive) (my/exwm-resize-window 'height 'grow)))
("k" (lambda () (interactive) (my/exwm-resize-window 'height 'shrink)))
("l" (lambda () (interactive) (my/exwm-resize-window 'width 'grow)))
("=" balance-windows)
("q" nil "quit" :color blue))
#+end_src
*** Improving splitting windows
=M-x evil-window-[v]split= (bound to =C-w v= and =C-w s= by default) are the default evil command to do splits.
One EXWM-related issue though is that by default doing such a split "copies" the current buffer to the new window. But as EXWM buffer cannot be "copied" like that, some other buffer is displayed in the split, and generally, that's not a buffer I want.
For instance, I prefer to have Chrome DevTools as a separate window. When I click "Inspect" on something, the DevTools window replaces my Ungoogled Chromium window. I press =C-w v=, and most often I have something like =*scratch*= buffer in the opened split instead of the previous Chromium window.
To implement better behavior, I define the following advice:
#+begin_src emacs-lisp
(defun my/exwm-fill-other-window (&rest _)
"Open the most recently used buffer in the next window."
(interactive)
(when (and (eq major-mode 'exwm-mode) (not (eq (next-window) (get-buffer-window))))
(let ((other-exwm-buffer
(cl-loop with other-buffer = (persp-other-buffer)
for buf in (sort (persp-current-buffers) (lambda (a _) (eq a other-buffer)))
with current-buffer = (current-buffer)
when (and (not (eq current-buffer buf))
(buffer-live-p buf)
(not (string-match-p (persp--make-ignore-buffer-rx) (buffer-name buf)))
(not (get-buffer-window buf)))
return buf)))
(when other-exwm-buffer
(with-selected-window (next-window)
(switch-to-buffer other-exwm-buffer))))))
#+end_src
This is meant to be called after doing an either vertical or horizontal split, so it's advised like that:
#+begin_src emacs-lisp
(advice-add 'evil-window-split :after #'my/exwm-fill-other-window)
(advice-add 'evil-window-vsplit :after #'my/exwm-fill-other-window)
#+end_src
This works as follows. If the current buffer is an EXWM buffer and there are other windows open (that is, =(next-window)= is not the current window), the function tries to find another suitable buffer to be opened in the split. And that also takes the perspectives into account, so buffers are searched only within the current perspective, and the buffer returned by =persp-other-buffer= will be the top candidate.
** Perspectives
[[https://github.com/nex3/perspective-el][perspective.el]] is one package I like that provides workspaces for Emacs, called "perspectives". Each perspective has a separate buffer list, window layout, and a few other things that make it easier to separate things within Emacs.
One feature I'd like to highlight is integration between perspective.el and [[https://github.com/Alexander-Miller/treemacs][treemacs]], where one perspective can have a separate treemacs tree. Although now tab-bar.el seems to be getting into shape to compete with perspective.el, as of the time of this writing, there's no such integration, at least not out of the box.
perspective.el works with EXWM more or less as one would expect - each EXWM workspace has its own set of perspectives. That way it feels somewhat like having multiple Emacs frames in a tiling window manager, although, of course, much more integrated with Emacs.
However, there are still some issues. For instance, I was having strange behaviors with floating windows, EXWM buffers in perspectives, etc. So I've made a package called [[https://github.com/SqrtMinusOne/perspective-exwm.el][perspective-exwm.el]] that does two things:
- Fixes issues I found with some advises and hooks. Take a look at the package homepage for more detail on that.
- Provides some additional functionality that makes use of both perspective.el and EXWM.
References:
- [[https://github.com/SqrtMinusOne/perspective-exwm.el][perspective-exwm.el repo]]
#+begin_src emacs-lisp
(use-package perspective-exwm
:straight t
:config
(setq perspective-exwm-override-initial-name
'((0 . "misc")
(1 . "core")
(2 . "browser")
(3 . "comms")
(4 . "dev")))
(general-define-key
:keymaps 'perspective-map
"e" #'perspective-exwm-move-to-workspace
"E" #'perspective-exwm-copy-to-workspace))
#+end_src
By default, a new Emacs buffer opens in the current perspective in the current workspace, but sure enough, it's possible to change that.
For EXWM windows, the =perspective-exwm= package provides a function called =perspective-exwm-assign-window=, which is intended to be used in =exwm-manage-finish-hook=, for instance:
#+begin_src emacs-lisp
(defun my/exwm-configure-window ()
(interactive)
(pcase exwm-class-name
((or "Firefox" "Nightly")
(perspective-exwm-assign-window
:workspace-index 2
:persp-name "browser"))
("Alacritty"
(perspective-exwm-assign-window
:persp-name "term"))
((or "VK" "Slack" "discord" "TelegramDesktop")
(perspective-exwm-assign-window
:workspace-index 3
:persp-name "comms"))
((or "Chromium-browser" "jetbrains-datagrip")
(perspective-exwm-assign-window
:workspace-index 4
:persp-name "dev"))))
(add-hook 'exwm-manage-finish-hook #'my/exwm-configure-window)
#+end_src
** Workspaces and multi-monitor setup
A section about improving management of EXWM workspaces.
Some features, common in other tiling WMs, are missing in EXWM out of the box, namely:
- a command to [[https://i3wm.org/docs/userguide.html#_focusing_moving_containers][switch to another monitor]];
- a command to [[https://i3wm.org/docs/userguide.html#move_to_outputs][move the current workspace to another monitor]];
- using the same commands to switch between windows and monitors.
Here's my take on implementing them.
*** Tracking recently used workspaces
First up though, we need to track the workspaces in the usage order. I'm not sure if there's some built-in functionality in EXWM for that, but it seems simple enough to implement.
Here is a snippet of code that does it:
#+begin_src emacs-lisp
(setq my/exwm-last-workspaces '(1))
(defun my/exwm-store-last-workspace ()
"Save the last workspace to `my/exwm-last-workspaces'."
(setq my/exwm-last-workspaces
(seq-uniq (cons exwm-workspace-current-index
my/exwm-last-workspaces))))
(add-hook 'exwm-workspace-switch-hook
#'my/exwm-store-last-workspace)
#+end_src
The variable =my/exwm-last-workspaces= stores the workspace indices; the first item is the index of the current workspace, the second item is the index of the previous workspace, and so on.
One note here is that workspaces may also disappear (e.g. after =M-x exwm-workspace-delete=), so we also need a function to clean the list:
#+begin_src emacs-lisp
(defun my/exwm-last-workspaces-clear ()
"Clean `my/exwm-last-workspaces' from deleted workspaces."
(setq my/exwm-last-workspaces
(seq-filter
(lambda (i) (nth i exwm-workspace--list))
my/exwm-last-workspaces)))
#+end_src
*** The monitor list
The second piece of the puzzle is getting the monitor list in the right order.
While it is possible to retrieve the monitor list from =exwm-randr-workspace-output-plist=, this won't scale well beyond two monitors, mainly because changing this variable may screw up the order.
So the easiest way is to just define the variable like that:
#+begin_src emacs-lisp :eval no
(setq my/exwm-monitor-list
(pcase (system-name)
("indigo" '(nil "DVI-D-0"))
(_ '(nil))))
#+end_src
If you are changing the RandR configuration on the fly, this variable will also need to be changed, but for now, I don't have such a necessity.
A function to get the current monitor:
#+begin_src emacs-lisp :eval no
(defun my/exwm-get-current-monitor ()
"Return the current monitor name or nil."
(plist-get exwm-randr-workspace-output-plist
(cl-position (selected-frame)
exwm-workspace--list)))
#+end_src
And a function to cycle the monitor list in either direction:
#+begin_src emacs-lisp
(defun my/exwm-get-other-monitor (dir)
"Cycle the monitor list in the direction DIR.
DIR is either 'left or 'right."
(nth
(% (+ (cl-position
(my/exwm-get-current-monitor)
my/exwm-monitor-list
:test #'string-equal)
(length my/exwm-monitor-list)
(pcase dir
('right 1)
('left -1)))
(length my/exwm-monitor-list))
my/exwm-monitor-list))
#+end_src
*** Switch to another monitor
With the functions from the previous two sections, we can implement switching to another monitor by switching to the most recently used workspace on that monitor.
One caveat here is that on the startup the =my/exwm-last-workspaces= variable won't have any values from other monitor(s), so this list is concatenated with the list of available workspace indices.
#+begin_src emacs-lisp
(defun my/exwm-switch-to-other-monitor (&optional dir)
"Switch to another monitor."
(interactive)
(my/exwm-last-workspaces-clear)
(let ((mouse-autoselect-window nil))
(exwm-workspace-switch
(cl-loop with other-monitor = (my/exwm-get-other-monitor (or dir 'right))
for i in (append my/exwm-last-workspaces
(cl-loop for i from 0
for _ in exwm-workspace--list
collect i))
if (if other-monitor
(string-equal (plist-get exwm-randr-workspace-output-plist i)
other-monitor)
(not (plist-get exwm-randr-workspace-output-plist i)))
return i))))
#+end_src
I bind this function to =s-q=, as I'm used from i3.
*** Move the workspace to another monitor
Now, moving the workspace to another monitor.
This is actually quite easy to pull off - one just has to update =exwm-randr-workspace-monitor-plist= accordingly and run =exwm-randr-refresh=. I just add another check there because I don't want some monitor to remain without workspaces at all.
#+begin_src emacs-lisp
(defun my/exwm-workspace-switch-monitor ()
"Move the current workspace to another monitor."
(interactive)
(let ((new-monitor (my/exwm-get-other-monitor 'right))
(current-monitor (my/exwm-get-current-monitor)))
(when (and current-monitor
(>= 1
(cl-loop for (key value) on exwm-randr-workspace-monitor-plist
by 'cddr
if (string-equal value current-monitor) sum 1)))
(error "Can't remove the last workspace on the monitor!"))
(setq exwm-randr-workspace-monitor-plist
(map-delete exwm-randr-workspace-monitor-plist exwm-workspace-current-index))
(when new-monitor
(setq exwm-randr-workspace-monitor-plist
(plist-put exwm-randr-workspace-monitor-plist
exwm-workspace-current-index
new-monitor))))
(exwm-randr-refresh))
#+end_src
In my configuration this is bound to =s-<tab>=.
*** Windmove between monitors
And the final (for now) piece of the puzzle is using the same command to switch between windows and monitors. E.g. when the focus is on the right-most window on one monitor, I want the command to switch to the left-most window on the monitor to the right instead of saying "No window right from the selected window", as =windmove-right= does.
So here is my implementation of that. It always does =windmove-do-select-window= for ='down= and ='up=. For ='right= and ='left= though, the function calls the previously defined function to switch to other monitor if =windmove-find-other-window= doesn't return anything.
#+begin_src emacs-lisp
(defun my/exwm-windmove (dir)
"Move to window or monitor in the direction DIR."
(if (or (eq dir 'down) (eq dir 'up))
(windmove-do-window-select dir)
(let ((other-window (windmove-find-other-window dir))

** Completions
Setting up some completion interfaces that fit particularly well to use with EXWM. While rofi also works, I want to use Emacs functionality wherever possible to have one completion interface everywhere.
*** ivy-posframe
[[https://github.com/tumashu/ivy-posframe][ivy-posframe]] is an extension to show ivy candidates in a posframe.
Take a look at [[https://github.com/ch11ng/exwm/issues/550][this issue]] in the EXWM repo about setting it up.
Edit <2022-04-09 Sat>: This looks nice, but unfortunately too unstable. Disabling it.

** Keybindings
*** EXWM keybindings
Setting keybindings for EXWM. This actually has to be in the =:config= block of the =use-package= form, that is it has to be run after EXWM is loaded, so I use noweb to put this block in the correct place.
First, some prefixes for keybindings that are always passed to EXWM instead of the X application in =line-mode=:
#+begin_src emacs-lisp :tangle no :noweb-ref exwm-keybindings

`(?\C-x

=i3lock= is disabled because the global one has to be used.
[[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+ and decided to switch to EXWM. This section is kept for a few cases when I need to be extra sure that my WM doesn't fail.
[[https://github.com/Airblader/i3][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.

** 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 $w9~ will move *any* window with a title starting with =ncmpcpp= to workspace =$w9=. For instance, it moves your browser when you google "ncmpcpp".

** 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 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.
#+begin_src bash :tangle ./bin/scripts/dropdown
CLASSNAME="dropdown_tmux"
COMMAND="alacritty --class $CLASSNAME -e tmux new-session -s $CLASSNAME"

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 situation.

| desktop-polybar | polybar | statusbar |
[[https://github.com/polybar/polybar][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.+ Still using polybar with EXWM and pretty happy with it.
Don't forget to install the Google Noto Color Emoji font. Guix package with all Noto fonts is way too large.
References:
- [[https://github.com/polybar/polybar/wiki][polybar docs]]
** General settings
In relation to literate configuration, this is the most +crazy+ advanced case of the former so far in my config.
My polybar has:
- colors from the general color theme;
- powerline-ish decorations between modules.
*** Colors
The "colors" part is straightforward enough. Polybar can use =Xresources=, so we just need to generate the appropriate bindings of Xresources to the polybar variables:
#+NAME: get-polybar-colors
#+begin_src emacs-lisp :var table=colors :tangle no
(mapconcat
(lambda (elem)
(format "%s = ${xrdb:%s}" (nth 0 elem) (nth 1 elem)))
(seq-filter
(lambda (elem) (when-let (name (nth 1 elem))
(not (string-empty-p name))))
table)
"\n")
#+end_src
#+begin_src conf-windows :noweb yes
[colors]
<<get-polybar-colors()>>
background = ${xrdb:background}
; foreground = ${xrdb:foreground}
#+end_src
*** Glyph settings
As for the module decorations though, I find it ironic that with all this fancy rendering around I have to resort to Unicode glyphs.
Anyhow, the approach is to put a glyph between two blocks like this:
#+begin_example
block1  block2
#+end_example
And set the foreground and background colors like that:
| | block1 | glyph | block2 |
|------------+--------+-------+---------|
| foreground | F1 | B2 | F2 |
| background | B1 | B1 | B2 |
So, that's a start. First, let's define the glyph symbols in the polybar config:
#+begin_src conf-windows
[glyph]
gleft = 
gright = 
#+end_src
*** Defining modules
As we want to interweave polybar modules with these glyphs in the right order and with the right colors, it is reasonable to define a single source of truth:
#+NAME: polybar_modules
| Index | Module | Color | Glyph |
|-------+-------------+---------------+-------|
| 1 | pulseaudio | light-magenta | + |
| 2 | mpd | magenta | + |
| 9 | battery | light-cyan | + |
| 3 | cpu | cyan | + |
| 4 | ram-memory | light-green | + |
| 5 | swap-memory | green | + |
| 6 | bandwidth | light-red | + |
| 7 | openvpn | light-red | |
| 8 | xkeyboard | red | + |
| 10 | weather | light-yellow | + |
| 12 | sun | yellow | + |
| 13 | aw-afk | light-blue | + |
| 14 | date | blue | + |
Also excluding some modules from certain monitors, which for now is about excluding =battery= from the monitors of my desktop PC:
#+NAME: polybar_modules_exclude
| Monitor | Exclude |
|----------+---------|
| DVI-D-0 | battery |
| HDMI-A-0 | battery |
Another thing we need to do is to set the color of modules in accordance with the =polybar_modules= table. The background can be determined from the =Color= column with the following code block:
#+NAME: get-polybar-bg
#+begin_src emacs-lisp :var table=polybar_modules module="pulseaudio"
(format
"${colors.%s}"
(nth
2
(seq-find
(lambda (el) (string-equal (nth 1 el) module))
table)))
#+end_src
That block is meant to be invoked in each module definition.
*** Generating glyphs
To generate the required set of glyphs, we need a glyph for every possible combination of adjacent colors that can occur in polybar.
Most of these combinations can be inferred from the =polybar_modules= table, the rest are defined in another table:
#+NAME: polybar_extra_colors
| Color 1 | Color 2 |
|------------+---------------|
| background | white |
| background | light-magenta |
| blue | background |
#+NAME: polybar-generate-glyphs
#+begin_src emacs-lisp :var table=polybar_modules exclude-table=polybar_modules_exclude extra=polybar_extra_colors
(let* ((monitors
(thread-last
exclude-table
(seq-map (lambda (el) (nth 0 el)))
(seq-uniq)))
(exclude-combinations
(seq-map
(lambda (monitor)
(seq-map
(lambda (el) (nth 1 el))
(seq-filter
(lambda (el) (and (string-equal (nth 0 el) monitor)
(nth 1 el)))
exclude-table)))
`(,@monitors "")))
(module-glyph-combinations
(thread-last
exclude-combinations
(seq-map
(lambda (exclude)
(thread-last
table
(seq-filter
(lambda (elt)
(not (or
(member (nth 1 elt) exclude)
(not (string-equal (nth 3 elt) "+")))))))))
(seq-uniq)))
(color-changes nil))
(dolist (e extra)
(add-to-list
'color-changes
(concat (nth 0 e) "--" (nth 1 e))))
(dolist (comb module-glyph-combinations)
(dotimes (i (1- (length comb)))
(add-to-list
'color-changes
(concat (nth 2 (nth i comb))
"--"
(nth 2 (nth (1+ i) comb))))))
(mapconcat
(lambda (el)
(let ((colors (split-string el "--")))
(format "
[module/glyph-%s--%s]
type = custom/text
content-background = ${colors.%s}
content-foreground = ${colors.%s}
content = ${glyph.gright}
content-font = 5"
(nth 0 colors)
(nth 1 colors)
(nth 0 colors)
(nth 1 colors))))
color-changes
"\n"))
#+end_src
Here's a rough outline of how the code works:
- =monitors= is a list of unique monitors in =exclude-table=
- =exclude-combilnations= is a list of lists of module names to be excluded for each monitor
- =module-glyphs-combinations= is a list of lists of actual modules for each monitor
- =color-changes= is a list of unique adjacent colors across modules in all monitors
Finally, =color-changes= is used to generate glyph modules that look like this:
#+begin_src conf-windows :tangle no
[module/glyph-light-cyan--cyan]
type = custom/text
content-background = ${colors.light-cyan}
content-foreground = ${colors.cyan}
content = ${glyph.gright}
content-font = 5
#+end_src
As of now, 15 of such modules is generated.
Include this to the polybar config itself:
#+begin_src conf-windows :noweb yes
<<polybar-generate-glyphs()>>
#+end_src
*** Generating set of modules
To configure polybar itself, we need to generate a set of modules for each monitor.
The parameters here, excluding the two required tables, are:
- =monitor= - the current monitor on which to filter out the blocks by the =polybar_modules_exclude= table,
- =first-color= - the first color of the first glyph,
- =last-color= - the second color of the last glyph.
#+NAME: polybar-generate-modules
#+begin_src emacs-lisp :var table=polybar_modules exclude-table=polybar_modules_exclude monitor="DVI-D-0" first-color="background" last-color="background"
(let* ((exclude-modules
(thread-last
exclude-table
(seq-filter (lambda (el) (string-equal (nth 0 el) monitor)))
(seq-map (lambda (el) (nth 1 el)))))
(modules
(thread-last
table
(seq-filter (lambda (el) (not (member (nth 1 el) exclude-modules))))))
(prev-color first-color)
(ret nil))
(concat
(mapconcat
(lambda (el)
(apply
#'concat
(list
(when (string-equal (nth 3 el) "+")
(setq ret (format "glyph-%s--%s " prev-color (nth 2 el)))
(setq prev-color (nth 2 el))
ret)
(nth 1 el))))
modules
" ")
(unless (string-empty-p last-color) (format " glyph-%s--%s " prev-color last-color))))
#+end_src
The polybar config doesn't support conditional statements, but it does support environment variables, so I pass the parameters from in the launch script.

** Individual 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 [[https://github.com/polybar/polybar/issues/615][it looks like this is impossible]].
If you want to copy something, you can go to the [[file:bin/polybar/][bin/polybar]] folder.

| 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?
[[https://github.com/jordansissel/keynav][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

"class_i = 'keynav'",
"class_g = 'keynav'",
]
#+end_src

|-----------------|
| picom |
[[https://github.com/yshui/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. [[https://github.com/ibhagwan/picom][ibhagwan/picom]] adds rounded corners) which seem to have some popularity, but I use the base one.

** 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 [[https://unix.stackexchange.com/questions/281131/compton-i3-tabbed-stacked-transparency-background-image][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%.
