** What is StumpWM?
:PROPERTIES:
:CUSTOM_ID: Introduction-What-is-StumpWM-oyycyb91u5j0
:END:
[[https://stumpwm.github.io/][StumpWM]] is a tiling window manager inheriting from [[http://www.nongnu.org/ratpoison/][RatPoison]], written
entirely in [[https://common-lisp.net/][Common Lisp]] and compiled with [[http://www.sbcl.org/][SBCL]]. While it is not an
dynamic tiling window manager like [[file:awesome.org][Awesome]] is, its ability of managing
windows in frames and using keychords with keymaps like Emacs does is
a huge plus for me, not to mention the fact its configuration file is
written in Common Lisp, a general programming language, a bit like
Awesome. This makes it an [[file:Deprecated/i3.org][i3]] on steroids, sort of. It also uses a lot
of Emacs’ concepts, which is great for an Emacs user such as myself.

** Why not EXWM then?
:PROPERTIES:
:CUSTOM_ID: Introduction-Why-not-EXWM-then-670dyb91u5j0
:END:
Sometimes, some actions within Emacs are blocking actions, making the
computer not usable while the command runs. It also does not play nice
with video games (pun intended), which is also a negative point for
me. And I also find EXWM more confusing overall than StumpWM.

** What this file is for
:PROPERTIES:
:CUSTOM_ID: Introduction-What-this-file-is-for-pnyg92a1u5j0
:END:
This file has two main goals:
- This will be the actual source code of my StumpWM
  configuration, thanks to Emacs’ org-mode, and thanks to org-mode’s
  literate config capabilities.

  Almost all of the visible source blocks if not all will be included
  in my configuration files through tangling, which can be done in
  Emacs when this file is opened through ~M-x org-babel-tangle~, which
  will write my configuration files based on the source blocks present
  in this document. This file is not only my config’s documentation,
  it /*is*/ my configuration.
- Be my documentation on my StumpWM configuration. That way, I’ll
  never forget which block of code does what.

  And maybe, hopefully, someone could learn a thing or two if they
  want to get into StumpWM but don’t know where to begin. You should
  be able to read this document as a book, with each chapter dedicated
  to a different aspect of StumpWM.

** Organization of my files
:PROPERTIES:
:CUSTOM_ID: Introduction-Organization-of-my-files-40vjne91u5j0
:END:
While I could make this file write everything to the same file (the
actual source will be in a single file after all), I find it easier to
debug StumpWM if everything’s split up. For now, my configuration
follows this architecture:
- ~init.el~ :: My main configuration file, glues everything together. It
  loads all of my configuration files as well as some modules I find
  useful;
- ~colors.lisp~ :: In this file are defined colors that will be used in
  common in my ~theme.lisp~ and ~modeline.lisp~ files. Let’s make my code
  DRY, or as I prefer to say, DRYD (/Don’t Repeat Yourself Dummy/).
- ~commands.lisp~ :: Lisp commands, in case I want to bind some
  complicated actions to a keybind that is not just a simple shell
  command;
- ~keybindings.lisp~ :: My list of keymaps and keybinds which make
  StumpWM actually usable;
- ~modeline.lisp~ :: This defines the modeline, a concept taken from
  Emacs which can display various information such as a list of
  workspaces, including the current one;
- ~placement.lisp~ :: This file manages my workspaces and the default
  placement of various windows;
- ~theme.lisp~ :: manages the color theme of StumpWM, the default
  placement of some windows and StumpWM’s gaps.

* Init file
:PROPERTIES:
:CUSTOM_ID: Init-file-l3q4snd1u5j0
:header-args:lisp: :mkdirp :tangle ~/.stumpwm.d/init.lisp
:END:
As mentioned in [[https://stumpwm.github.io/git/stumpwm-git_1.html#Init-File][the documentation]], the configuration files can be in
different locations, but I chose an Emacs-like configuration: put
everything in ~~/.stumpwm.d/~. We begin by indicating quicklisp how to
properly initialize:
#+begin_src lisp
#-quicklisp
(let ((quicklisp-init (merge-pathnames "quicklisp/setup.lisp"
                                       (user-homedir-pathname))))
  (when (probe-file quicklisp-init)
    (load quicklisp-init)))
#+end_src

Then, our first StumpWM-related code is declaring we are using the
~stumpwm~ package, and this is also our default package. This will allow
us to avoid using the prefix ~stumpwm:~ each time we are using a
function or a variable from this package.
#+begin_src lisp
(in-package :stumpwm)
(setf *default-package* :stumpwm)
#+end_src

Since I install StumpWM with my package manager (I use the AUR’s
~stumpwm-git~ package), StumpWM’s modules are installed to
~/usr/share/stupmwm/contrib/utils/~, let’s indicate that to StumpWM.
#+begin_src lisp
(set-module-dir "/usr/share/stupmwm/contrib/")
#+end_src

A startup message can be used when initializing StumpWM. For now,
let’s set it to ~nil~.
#+begin_src lisp
(setf *startup-message* nil)
#+end_src

The first thing I want to do after that is to set some decent cursor
pointer as well as get a bunch of stuff started. To see what’s in the
~autostart~ script, [[file:bin.org::#Autostart-a99e99e7][see here]].
#+begin_src lisp
(run-shell-command "xsetroot -cursor_name left_ptr")
(run-shell-command "autostart")
#+end_src

Now, we’ll load a couple of my custom files that will be described below:
#+name: first-loaded-files
| File to be loaded |
|-------------------|
| commands.lisp     |
| placement.lisp    |
| keybindings.lisp  |
| theme.lisp        |
| modeline.lisp     |

#+name: gen-load-files
#+headers: :wrap src lisp
#+begin_src emacs-lisp :var files=first-loaded-files
(mapconcat (lambda (file)
             (format "(load \"~/.stumpwm.d/%s\")" (car file)))
           files
           "\n")
#+end_src

This is equivalent to the Common Lisp code:
#+RESULTS[942558619eb0d0a3d694a7808d0b600f0bc4c14c]: gen-load-files
#+begin_src lisp
(load "~/.stumpwm.d/commands.lisp")
(load "~/.stumpwm.d/placement.lisp")
(load "~/.stumpwm.d/keybindings.lisp")
(load "~/.stumpwm.d/theme.lisp")
(load "~/.stumpwm.d/modeline.lisp")
#+end_src

Once the modeline file is loaded, let’s indicate StumpWM to activate
it:
#+begin_src lisp
(when *initializing*
  (mode-line))
#+end_src

Another thing I want to set is how focus is linked to my mouse: only
on click. I /HATE/ it when focus follows my mouse like some damn dog
after its ball. Also, the meta key will be used to move floating
windows.
#+begin_src lisp
(setf *mouse-focus-policy*    :click
      ,*float-window-modifier* :META)
#+end_src

Next, some modules will be loaded from the ~stumpwm-contrib~ package
(which is included in ~stumpwm-git~ in the AUR). Here is a short list
including a short description of what they are for:
#+name: loaded-modules
| Module Name     | Why It Is Loaded                                           |
|-----------------+------------------------------------------------------------|
| alert-me        | Creates notifications, can also create timed notifications |
| beckon          | Bring the mouse cursor to the current window               |
| end-session     | Gracefully end programs when ending user session           |
| globalwindows   | Navigate between windows from all workspaces               |
| stump-backlight | Native management of backlight in StumpWM                  |
| urgentwindows   | Get urgent windows                                         |

#+name: gen-load-modules
#+headers: :wrap src lisp
#+begin_src emacs-lisp :var modules=loaded-modules
(mapconcat (lambda (module)
             (format "(load-module \"%s\")" (car module)))
           modules
           "\n")
#+end_src

#+RESULTS[508e36f9747f1da901bbee63582416a8a6ba2c2f]: gen-load-modules
#+begin_src lisp
(load-module "alert-me")
(load-module "beckon")
(load-module "end-session")
(load-module "globalwindows")
(load-module "stump-backlight")
(load-module "urgentwindows")
#+end_src

Finally, we can notify the user everything is ready.
#+begin_src lisp
(setf *startup-message* "StumpWM is ready!")
#+end_src

And it’s done! We can now move on to the creation of the other CLisp files.

* Commands
:PROPERTIES:
:CUSTOM_ID: Commands-1wagy001v5j0
:header-args:lisp: :mkdirp :tangle ~/.stumpwm.d/commands.lisp
:END:
The first command I declare in this file is a command that will avoid
me invoking too many Firefox instances. Either Firefox is not already
running and an instance is launched, or one already is and we are
brought to it. This is done like so:
#+begin_src lisp
(defcommand firefox () ()
            "Run or raise Firefox."
            (run-or-raise "firefox" '(:class "Firefox") t nil))
#+end_src

Next, this command will not only close the current window, but it will
also close the current frame.
#+begin_src lisp
(defcommand delete-window-and-frame () ()
            "Delete the current frame with its window."
            (delete-window)
            (remove-split))
#+end_src

The two following commands will create a new frame to the right and
below the current frame respectively, then focus it.
#+begin_src lisp
(defcommand hsplit-and-focus () ()
            "Create a new frame on the right and focus it."
            (hsplit)
            (move-focus :right))

(defcommand vsplit-and-focus () ()
            "Create a new frame below and move focus to it."
            (vsplit)
            (move-focus :down))
#+end_src

Now, let’s create a command for invoking the terminal, optionally with
a program.
#+begin_src lisp
(defcommand term (&optional program) ()
            "Invoke a terminal, possibly with a @arg{program}."
            (run-shell-command (if program
                                   (format nil "kitty ~A" program)
                                   "kitty")))
#+end_src

And done! Next!

* Colors
:PROPERTIES:
:CUSTOM_ID: Colors-w5493d01v5j0
:header-args:lisp: :mkdirp :tangle ~/.stumpwm.d/colors.lisp
:END:
If you’ve taken a look at the rest of my dotfiles, you may have
noticed I really like the [[https://www.nordtheme.com/][Nord theme]]. No wonder we can find it here
again! Here is a small table listing the Nord colors:
#+name: nord-colors
| Name   | Value   |
|--------+---------|
| nord0  | #2e3440 |
| nord1  | #3b4252 |
| nord2  | #434c5e |
| nord3  | #4c566a |
| nord4  | #d8dee9 |
| nord5  | #e5e9f0 |
| nord6  | #eceff4 |
| nord7  | #8fbcbb |
| nord8  | #88c0d0 |
| nord9  | #81a1c1 |
| nord10 | #5e81ac |
| nord11 | #bf616a |
| nord12 | #d08770 |
| nord13 | #ebcb8b |
| nord14 | #a3be8c |
| nord15 | #b48ead |

I’ll prefix the variables’ name with ~phundrak-~ just in case it might
conflict with another package I might use in the future, so the CLisp
code looks like so:
#+name: gen-colors
#+headers: :wrap src lisp
#+begin_src emacs-lisp :var colors=nord-colors
(mapconcat (lambda (color)
             (format "(defvar phundrak-%s \"%s\")" (car color) (cadr color)))
           colors
           "\n")
#+end_src

#+RESULTS[08b3db7a2b4f31d641bcd096ff265eae06879244]: gen-colors
#+begin_src lisp
(defvar phundrak-nord0 "#2e3440")
(defvar phundrak-nord1 "#3b4252")
(defvar phundrak-nord2 "#434c5e")
(defvar phundrak-nord3 "#4c566a")
(defvar phundrak-nord4 "#d8dee9")
(defvar phundrak-nord5 "#e5e9f0")
(defvar phundrak-nord6 "#eceff4")
(defvar phundrak-nord7 "#8fbcbb")
(defvar phundrak-nord8 "#88c0d0")
(defvar phundrak-nord9 "#81a1c1")
(defvar phundrak-nord10 "#5e81ac")
(defvar phundrak-nord11 "#bf616a")
(defvar phundrak-nord12 "#d08770")
(defvar phundrak-nord13 "#ebcb8b")
(defvar phundrak-nord14 "#a3be8c")
(defvar phundrak-nord15 "#b48ead")
#+end_src

And with that we’re done!

* Modeline
:PROPERTIES:
:CUSTOM_ID: Modeline-g2ofyw01v5j0
:header-args:lisp: :mkdirp :tangle ~/.stumpwm.d/modeline.lisp
:END:
The modeline is pretty easy. First, let’s load the ~colors.lisp~ file we just created:
#+begin_src lisp
(load "~/.stumpwm.d/colors.lisp")
#+end_src

Next, we can set some colors for the modeline. Let’s set the
background of the modeline to Nord1 and the foreground to Nord5, I
think this is a pretty good combination.
#+begin_src lisp
(setf *mode-line-background-color* phundrak-nord1
      ,*mode-line-foreground-color* phundrak-nord5)
#+end_src

We /could/ also use some borders in the modeline. But we won’t. Let’s
still set its color to Nord1, just in case.
#+begin_src lisp
(setf *mode-line-border-color* phundrak-nord1
      ,*mode-line-border-width* 0)
#+end_src

The timeout of the modeline indicates how often it refreshes in
seconds. I think one second is good.
#+begin_src lisp
(setf *mode-line-timeout* 1)
#+end_src

Next we get to the content of the modeline. This format follows the
format indicated in the manpage of ~date~.
#+begin_src lisp
(setf *time-modeline-string* "%F %H:%M")
#+end_src

Let’s also indicate how the groupname is displayed.
#+begin_src lisp
(setf *group-format* "%t")
#+end_src

The window format should display first its window number, then its
titled, limited to 30 characters.
#+begin_src lisp
(setf *window-format* "%n: %t")
#+end_src

Here are some modules that we will load for the modeline:
#+name: modeline-modules
| Module Name      | Why It Is Loaded                                 |

           modules
           "\n")
#+end_src

      wifi:*use-colors* nil
      ,*mode-line-highlight-template* "<~A>"
      ,*hidden-window-color* "^**")
#+end_src

We can indicate what to display in our modeline. Each formatter will
be separated by a Powerline separator with the code point ~0xE0B0~ in
the font I am using (see §[[#Theme-Fonts-28pc8141v5j0]]).
#+name: modeline-format

#+end_src

This variable as you can see is a list of elements, although here I am
only using one string. But it is completely possible to insert some
CLisp code in here that returns some string if the user needs some
code to return data that cannot be easily accesible otherwise. I might
add some at some point, but not today yet.

Groups are specified this way:
#+begin_src lisp
(when *initializing*
  <<gen-groups()>>)
#+end_src

By default, if nothing is specified as per the group type, my groups
are manual tiling groups. Otherwise, as you can see above, they can
also be dynamic tiling groups or floating groups.

Next, let’s make sure no previous window placement rule is in place,
this will avoid unexpected and hard-to-debug behavior.
#+begin_src lisp
(clear-window-placement-rules)
#+end_src

As you can see in the table [[list-groups]] above, I also indicated my
window placement preferences. For now, they all rely on the window’s
class, so it will be pretty straightforward to the corresponding code.
#+name: gen-rules

This can be written this way:

#+end_src

Now, let’s do some automation. The reason why I want the first group
to be a dynamic group is so that all terminal windows I’ll have there
will be automatically arranged. If I switch to the ~[SYS]~ group, I want
three terminal windows to open by default:
- an ~htop~ window
- and two terminals
This can be done like so:
#+begin_src lisp
(defun my-term-init (current-group _last-group)
  "Create terminals in the first group when none are already there."
  (let ((term-group (select-group (current-screen) "2"))
        (windows    (group-windows current-group)))
    (when (and (equal current-group term-group)
               (null windows))
      (unless (= 1 (length (group-frames current-group)))
        (only))
      (term "htop")
      (term)
      (term))))
#+end_src

Let’s add a hook for that now:
#+begin_src lisp
(add-hook *focus-group-hook* 'my-term-init)
#+end_src

By the way, dynamic groups should have a split ratio of half of the
available space.
#+begin_src lisp
(setf *dynamic-group-master-split-ratio* 1/2)
#+end_src

* Theme
:PROPERTIES:
:CUSTOM_ID: Theme-1x3c2u31v5j0
:header-args:lisp: :mkdirp :tangle ~/.stumpwm.d/theme.lisp :noweb yes
:END:
As in the modeline file, the first thing we’ll do is to load our colors.
#+begin_src lisp
(load "~/.stumpwm.d/colors.lisp")
#+end_src

We can now go onto more serious business.

** Fonts
:PROPERTIES:
:CUSTOM_ID: Theme-Fonts-28pc8141v5j0
:END:
This gave me quite the headache when I tried to set this up: in order
to use TTF or OTF fonts, we need to use the ~ttf-fonts~ module which
relies on the ~clx-truetype~ library. A few years back, it should have
been possible to get it installed with a call to src_lisp[:exports
code]{(ql:quickload :clx-truetype)}, but it is no longer available!
There’s a quickfix available while we wait for ~clx-truetype~ to be once
again available: clone it in quicklisp’s local projects. You will
obviously need to have quicklisp installed (for that, follow the
[[https://www.quicklisp.org/beta/#installation][official instructions]]), then execute the following shell commands:
#+begin_src sh :dir ~/quicklisp/local-projects
cd ~/quicklisp/local-projects/
git clone https://github.com/lihebi/clx-truetype.git
#+end_src

This will make ~clx-truetype~ available to quicklisp, and you can run
again src_lisp[:exports code]{(ql:quickload :clx-truetype)} without an
issue (running it again is necessary to install its dependencies).

Now that this is out of the way, let’s add two lines so we can use TTF
fonts:
#+begin_src lisp
(ql:quickload :clx-truetype)
(load-module "ttf-fonts")
#+end_src

The documentation says we should be able to also use OTF fonts, but so
far I’ve had no luck loading one.

Loading more than one font to use
some fallback fonts also doesn’t seem to work, unlike specified in the
documentation (I wanted to use a CJK font, but it doesn’t appear to
work), we need to manually change the font used which isn’t very
user-friendly, especially if you might have CJK characters appear in
otherwise regular text.

Something that didn’t click immediately for me (and I think StumpWM’s
documentation on this could be improved) is that ~set-font~ can be used
to set either one main font for StumpWM, as one might guess reading
the documentation --- or you can set a list of them! And this is
great, since my main font does not support some characters I regularly
have in my windows’ title, such as CJK characters! However, be aware
*the second font and further aren’t fallback fonts*. They are additional
fonts you can switch to manually through the use of ~^f<n>~ (~<n>~ being
the desired’s font index in the 0-indexed font list). But if a font
cannot render a character, it will simply display an empty rectangle
instead of falling back to another font. That’s annoying… Here is my
list of fonts I want loaded:
#+name: list-fonts
| Family                         | Subfamily | Size |
|--------------------------------+-----------+------|
| Unifont-JP                     | Regular   |   10 |
| DejaVu Sans Mono for Powerline | Book      |  8.5 |

#+name: gen-fonts
#+headers: :wrap src lisp
#+begin_src emacs-lisp :var fonts=list-fonts
(format "(set-font `(%s))"
        (mapconcat (lambda (font)
                    (let ((family    (nth 0 font))
                          (subfamily (nth 1 font))
                          (size      (nth 2 font)))
                      (format ",%s" `(make-instance 'xft:font
                                                    :family ,(format "\"%s\"" family)
                                                    :subfamily ,(format "\"%s\"" subfamily)
                                                    :size ,size
                                                    :antialias t))))
                  fonts
                  "\n            "))
#+end_src

The code equivalent of this table can be seen below:
#+RESULTS[2bcc2bbfd79a25c20b4dfa9d9867b91797089ffc]: gen-fonts
#+begin_src lisp
(set-font `(,(make-instance 'xft:font :family "Unifont-JP" :subfamily "Regular" :size 10 :antialias t)
            ,(make-instance 'xft:font :family "DejaVu Sans Mono for Powerline" :subfamily "Book" :size 8.5 :antialias t)))
#+end_src

As far as I know, Unifont is the only font I’ve tested that displays
monospaced Japanese characters in StumpWM. I tried DejaVu, IBM Plex,
and a couple of others but only this one works correctly. DejaVu is
here for the Powerline separator. If you know of another monospaced
font that displays Japanese characters, or even better CJK characters,
please tell me! My email address is at the bottom of this webpage.

** Colors
:PROPERTIES:
:CUSTOM_ID: Theme-Colors-ctlclb51v5j0
:END:
We can now set a couple of colors for StumpWM. Not that we will see
them often since I don’t like borders on my windows, but in case I
want to get them back, they’ll be nice to have.
#+begin_src lisp
(set-border-color        phundrak-nord1)
(set-focus-color         phundrak-nord1)
(set-unfocus-color       phundrak-nord3)
(set-float-focus-color   phundrak-nord1)
(set-float-unfocus-color phundrak-nord3)
#+end_src

Let’s also set the colors of the message and input windows:
#+begin_src lisp
(set-fg-color phundrak-nord4)
(set-bg-color phundrak-nord1)
#+end_src

As I said, I don’t like borders, so I’ll remove them. I’ll still keep
the window’s title bar available when it’s floating, and this is also
where I can set the format of its title: its number as well as its
name, limited to thirty characters.
#+begin_src lisp
(setf *normal-border-width*       0
      ,*float-window-border*       0
      ,*float-window-title-height* 15
      ,*window-border-style*       :none
      ,*window-format*             "%n:%t")
#+end_src

** Message and Input Windows
:PROPERTIES:
:CUSTOM_ID: Theme-Message-and-Input-Windows-jxwhch51v5j0
:END:
The Input windows as well as the message windows should both be at the
top of my screen. And I believe a padding of five pixels for the
message windows is good.
#+begin_src lisp
(setf *input-window-gravity*     :top
      ,*message-window-padding*   10
      ,*message-window-y-padding* 10
      ,*message-window-gravity*   :top)
#+end_src

** Gaps Between Frames
:PROPERTIES:
:CUSTOM_ID: Theme-Gaps-Between-Frames-bqngnt51v5j0
:END:
I love gaps. When I was using i3, I used the ~i3-gaps~ package, not just
plain ~i3~. In Awesome, I still have gaps. And in StumpWM, I shall still
use gaps. In order to use them, let’s load a module dedicated to gaps
in StumpWM:
#+begin_src lisp
(load-module "swm-gaps")
#+end_src

Now that this is done, I can now set some variables bound to this
package.
#+begin_src lisp
(setf swm-gaps:*head-gaps-size*  0
      swm-gaps:*inner-gaps-size* 5
      swm-gaps:*outer-gaps-size* 10)
#+end_src

Finally, let’s enable our gaps:
#+begin_src lisp
(when *initializing*
  (swm-gaps:toggle-gaps))
#+end_src

* Keybinds
:PROPERTIES:
:CUSTOM_ID: Keybinds-c6wgf961v5j0
:header-args:lisp: :mkdirp :tangle ~/.stumpwm.d/keybindings.lisp :noweb yes
:END:
Buckle up, this chapter is going to be *long*, because me loves LOTS of keybinds.

First, let’s declare again we are using the default package ~stumpwm~:
#+begin_src lisp
(in-package :stumpwm)
#+end_src

This will avoid us always repeating ~stumpwm:define-key~ or ~stumpwm:kbd~
instead of simply ~define-key~ and ~kbd~.

StumpWM behaves a bit like Emacs in terms of keybinds. You have
keymaps, which are a collection of keybinds, which in turn call CLisp
functions. However, unlike Emacs, you have to declare a lot of
keymaps, because StumpWM cannot (/yet/) understand keybinds such as
src_lisp[:exports code]{(kbd "C-x c l")}, so you end up creating a
keybind to a keymap which contains other keybinds, which might contain
a couple of keybinds to other keymaps. I hope this will get improved
soon.

There are also two keymaps you need to be aware of:
- ~*top-map*~ :: This is the keymap available litteraly everywhere. With
  this keymap, you can emulate most of your keybinds you have in other
  window managers. For instance, I cannot live without ~s-RET~ for
  creating new shells, so I’ll bind it to ~*top-map*~. But it’s good
  practice to avoid polluting ~*top-map*~ with too many keybinds.
- ~*root-map*~ :: This keymap is the default keymap that is already
  somewhat populated. It is available after hitting the prefix key set
  with ~set-prefix-key~ which we will see just below.

It is interesting to note that once you entered any keymap, except
~*top-map*~, if you hit ~?~ you will see the list of available keybinds.
I’d like it if something similar to ~general~ in Emacs too could be
implemented: give any arbitrary name to the keybind you just declared
which would be displayed instead of the actual function or keymap
called by keybind. It would be nicer to see ~frames~ rather than
~*my-frames-management-keymap*~.

Anyways, as mentionned above, ~*root-map*~ is already pre-populated with
some cool stuff for you, and you can access it with a prefix which is
by default ~C-t~. But if this doesn’t suit you, you can always redefine
it with ~set-prefix-key~. I personally like to have my space key as a
leader key, but in order to not have it conflict with Emacs, I also
need to press the super key too.
#+begin_src lisp
(set-prefix-key (kbd "s-SPC"))
#+end_src

Also, let’s enable ~which-key~:
#+begin_src lisp
(which-key-mode)
#+end_src

Lastly, before we get more into details, keep in mind that I use the
[[https://bepo.fr][bépo]] layout, as I often say in my different documents. This means the
characters found in the numbers’ row when pressing shift are actually
the numbers themselves. Also, some characters are not recognized as is
by ~kbd~, so we need to use a special name (not fun…). Below are the
following characters:
#+name: number-to-char-table
| Number | Character | Lisp Character |
|--------+-----------+----------------|
|      1 | ~"~         |                |
|      2 | ~«~         | ~guillemotleft~  |
|      3 | ~»~         | ~guillemotright~ |
|      4 | ~(~         |                |
|      5 | ~)~         |                |
|      6 | ~@~         |                |
|      7 | ~+~         |                |
|      8 | ~-~         |                |
|      9 | ~/~         |                |
|      0 | ~*~         |                |

So if you see any weird keybind involving these characters, this is
because of my layout.

** Applications
:PROPERTIES:
:CUSTOM_ID: Keybinds-Applications-2t512k00w5j0
:END:
When I speak about applications, I speak about programs and scripts in
general. With these keymaps, I can launch programs I often have use
for, but I can also launch some scripts as well as take screenshots.

First, let’s create my ~rofi~ scripts keymap.
#+name: rofi-scripts
#+caption: ~*my-rofi-keymap*~
| Keychord | Function                                      |
|----------+-----------------------------------------------|
| ~a~        | ~exec awiki~                                    |
| ~r~        | ~exec rofi -combi-modi drun,window -show combi~ |
| ~s~        | ~exec rofi -show ssh~                           |
| ~p~        | ~exec rofi-pass -t~                             |
| ~P~        | ~exec rofi-pass~                                |
| ~e~        | ~exec rofi-emoji~                               |
| ~m~        | ~exec rofi-mount~                               |
| ~u~        | ~exec rofi-umount~                              |
| ~w~        | ~exec wacom-setup~                              |
| ~y~        | ~exec ytplay~                                   |
| ~Y~        | ~exec rofi-ytdl~                                |

Here’s the equivalent in Common Lisp.
#+begin_src lisp
(defvar *my-rofi-keymap*
  (let ((m (make-sparse-keymap)))
    <<keybinds-gen(map="m", keybinds=rofi-scripts)>>
    m))
#+end_src

Let’s also create a keymap for screenshots.
#+name: screenshot-keymap
#+caption: ~*my-screenshot-keymap*~
| Keychord | Function                                             |
|----------+------------------------------------------------------|
| ~d~        | ~exec scrot -d 3 -e 'mv $f ~/Pictures/Screenshots'~     |
| ~s~        | ~exec scrot -e 'mv $f ~/Pictures/Screenshots'~          |
| ~S~        | ~exec scrot -s -e 'mv $f ~/Pictures/Screenshots'~       |
| ~g~        | ~exec scrot -e 'gimp $f; mv $f ~/Pictures/Screenshots'~ |

Here’s the equivalent in Common Lisp.
#+begin_src lisp
(defvar *my-screenshot-keymap*
  (let ((m (make-sparse-keymap)))
    <<keybinds-gen(map="m", keybinds=screenshot-keymap)>>
    m))
#+end_src

We can now define our applications keymap which will reference both
the above keymaps.
#+name: application-keymap
#+caption: ~*my-applications-keymap*~
| Keychord | Function                |
|----------+-------------------------|
| ~b~        | ~firefox~                 |
| ~d~        | ~exec lightcord~          |
| ~e~        | ~exec emacsclient -c~     |
| ~g~        | ~exec gimp~               |
| ~n~        | ~exec nemo~               |
| ~r~        | ~'*my-rofi-keymap*~       |
| ~s~        | ~'*my-screenshot-keymap*~ |

This translates to:

The application keymap can now be bound to the root map like so:
#+begin_src lisp
(define-key *root-map* (kbd "a") '*my-applications-keymap*)
#+end_src

I will also bind to the top map ~s-RET~ in order to open a new terminal
window. The screenshot keymap is also bound to the ScreenPrint key.
#+begin_src lisp
(define-key *top-map* (kbd "s-RET") "term")
(define-key *top-map* (kbd "Print") '*my-screenshot-keymap*)
#+end_src

** End of Session, Powering Off, and the Likes
:PROPERTIES:
:CUSTOM_ID: Keybinds-End-of-Session-Powering-Off-and-the-Likes-mgz02z40w5j0
:END:
The module ~end-session~ provides functions for gracefully ending the
user session, powering off, restarting, and suspending the computer.
It also provides a function that interactively asks what the user
whishes to do.
#+name: end-session-keymap

This translates to:

  (let ((m (make-sparse-keymap)))
    <<keybinds-gen(map="m", keybinds=end-session-keymap)>>

Which is bound in the root map to ~q~:

#+end_src

** Groups
:PROPERTIES:
:CUSTOM_ID: Keybinds-Groups-daxfwu40a7j0

A basic keybind I need for groups is to be able to switch from one
another. I’m very used to the ability of being able to jump between
them with the keybind Super + /number of the group/, so let’s define
this:

#+name: group-keybind-gen

#+begin_src emacs-lisp :var groups=list-groups mod="s" action="gselect" map="*top-map*" convert="yes"

                                             mod
                                             (if (string= "yes" convert)
                                                 (format "<<num-to-char(num=%s)>>" group-nbr)

                               ,(format "%s %d" action group-nbr)))))
           groups

Another batch of keybinds I use a lot is keybinds to send the
currently active window to another group, using Super + Shift + /number
of the group/. As mentioned before, due to my keyboard layout Shift +
/number/ is actually just /number/ for me (e.g. Shift + ~"~ results in ~1~),
so there’s no need to convert the group number to another character.
#+begin_src emacs-lisp :wrap src lisp

If I want to send a window to another group without following it, I’ll
use ~s-S-C-<group number>~, which gives us the following:
#+begin_src emacs-lisp :wrap src lisp
<<group-keybind-gen(mod="s-C", action="gmove-and-follow", convert="no")>>

And if I want to bring the windows of another group into the current
group, I’ll use ~s-C-<group number>~:
#+begin_src emacs-lisp :wrap src lisp :exports results

StumpWM also has already a nice keymap for managing groups called
~*groups-map*~, so let’s bind it to ~*root-map*~ too! (It’s actually
already bound, but since I plan on erasing ~*root-map*~ in the near
future before binding stuff to it, I prefer to bind it already)
#+begin_src lisp
(define-key *root-map* (kbd "g") '*groups-map*)
#+end_src

And a binding to ~vgroups~ is done on ~*groups-map*~ in order to regroup
similar keybinds.
#+begin_src lisp
(define-key *groups-map* (kbd "G") "vgroups")
#+end_src

I grew accustomed to ~s-ESC~ bringing me to the previous group when
using AwesomeWM, so let’s define that:
#+begin_src lisp
(define-key *top-map* (kbd "s-ESC") "gother")
#+end_src

** Frames and Windows management
:PROPERTIES:
:CUSTOM_ID: Keybinds-Frames-and-Windows-management-g4s6j371v5j0
:END:
As you’ll see, I have loads of keybinds related to frames and windows
management. They are all categorized in a specific keymap, called
~*my-frames-management-keymap*~. But before that, let’s define the
keymap ~*my-frames-float-keymap*~, with keybinds dedicated to actions
related with floating windows and frames.

#+name: frames-float
#+caption: ~*my-frames-float-keymap*~
| Keychord | Function       |
|----------+----------------|
| ~f~        | ~float-this~     |
| ~F~        | ~unfloat-this~   |
| ~u~        | ~unfloat-this~   |
| ~C-f~      | ~flatten-floats~ |

We can now pass onto ~*my-frames-management-keymap*~. My keybinds are organized this way:
#+name: frames-and-window-management
#+caption: ~*my-frames-management-keymap*~
| Keychord | Function                  |
|----------+---------------------------|

| ~.~        | ~iresize~                   |
| ~+~        | ~balance-frames~            |
| ~d~        | ~remove-split~              |
| ~D~        | ~only~                      |
| ~e~        | ~expose~                    |
| ~f~        | ~fullscreen~                |
| ~F~        | ~'*my-frames-float-keymap*~ |
| ~i~        | ~info~                      |
| ~I~        | ~show-window-properties~    |

| ~U~        | ~unmaximize~                |

As you can see, with the binding to ~F~, we make use of the
~*my-frames-float-keymap*~ keymap declared above, which means if we find
ourselves in ~*my-frames-management-keymap*~, pressing ~F~ will bring us
in ~*my-frames-float-keymap*~.

#+begin_src lisp
(defvar *my-frames-float-keymap*
  (let ((m (make-sparse-keymap)))
    <<keybinds-gen(map="m", keybinds=frames-float)>>
    m))

(defvar *my-frames-management-keymap*
  (let ((m (make-sparse-keymap)))
    <<keybinds-gen(map="m", keybinds=frames-and-window-management)>>
    m))
#+end_src

Let’s bind ~*my-frames-management-keymap*~ in ~*root-keymap*~:
#+begin_src lisp
(define-key *root-map* (kbd "w") '*my-frames-management-keymap*)
#+end_src

That way, if we want for instance to split our current frame
vertically, we’ll be able to type ~s-SPC w -~ and ~vsplit~ will be called.

I also bound a couple of these functions to the top keymap for easier access:
#+name: top-window-map
| Keychord | Function                 |
|----------+--------------------------|
| ~s-c~      | ~move-focus left~          |
| ~s-t~      | ~move-focus down~          |
| ~s-s~      | ~move-focus up~            |
| ~s-r~      | ~move-focus right~         |
| ~s-C~      | ~move-window left~         |
| ~s-T~      | ~move-window down~         |
| ~s-S~      | ~move-window up~           |
| ~s-R~      | ~move-window right~        |
| ~s-M-c~    | ~exchange-direction left~  |
| ~s-M-t~    | ~exchange-direction down~  |
| ~s-M-s~    | ~exchange-direction up~    |
| ~s-M-r~    | ~exchange-direction right~ |

This translates to:
#+begin_src lisp
<<keybinds-gen(map="*top-map*", keybinds=top-window-map)>>
#+end_src

Being a [[https://bepo.fr/wiki/Accueil][bépo layout]] user, the ~hjkl~ keys don’t exactly fit me, as you
might have noticed with my use of ~ctsr~ which is its equivalent. Due to
this, the interactive keymap for ~iresize~ is not ideal for me, let me
redefine it:
#+begin_src lisp
(define-interactive-keymap (iresize tile-group) (:on-enter #'setup-iresize
                                                 :on-exit  #'resize-unhide
                                                 :abort-if #'abort-resize-p)
  ((kbd "c") "resize-direction left")
  ((kbd "t") "resize-direction down")
  ((kbd "s") "resize-direction up")
  ((kbd "r") "resize-direction right"))
#+end_src

As with groups management, I grew used to ~s-TAB~ in AwesomeWM bringing
me back to the previously focused window.
#+begin_src lisp
(define-key *top-map* (kbd "s-TAB") "other-window")
#+end_src

** Media and Media Control
:PROPERTIES:
:CUSTOM_ID: Keybinds-Media-and-Media-Control-hbv5uk91z5j0
:END:
My music is managed through MPD, and I often use ~mpc~ commands in order
to interact with it without any GUI application. So, we’ll see a lot
of its usage here.

First, let’s declare an interactive keymap in order to easily change
several times in a row either the current song playing or the volume
of MPD.
#+name: inter-mpc
#+caption: Interactive keybinds for ~mpc~
| Keychord | Function           |

| ~r~        | ~exec mpc next~      |

Cela donne le code suivant:
#+begin_src lisp
<<interactive-gen(name="mpc-interactive", keys=inter-mpc)>>
#+end_src

Another one will be defined for the general audio of my computer. And
I know it isn’t technically media keybinds, but I’ll add in keybinds
for my screen’s backlight.
#+name: inter-media

| ~m~    | ~exec amixer -q set Master 1+ toggle~  |

#+begin_src lisp
<<interactive-gen(name="media-interactive", keys=inter-media)>>
#+end_src

Then, let’s declare a keymap for our media controls.
#+name: media-management

| ~N~        | ~term ncmpcpp -q~             |
| ~v~        | ~term ncmpcpp -qs visualizer~ |

Let’s translate this table in CommonLisp:
#+begin_src lisp

    <<keybinds-gen(map="m", keybinds=media-management)>>
    m))

(define-key *root-map* (kbd "m") '*my-media-keymap*)
#+end_src

I will also define on ~*top-map*~ some basic volume management keybinds
so that they are immediately accessible. Again, this isn’t technically
media-related, but I’ll add keybinds for my screen’s backlight.

From time to time, I need to switch between different keyboard
layouts, especially to the US Qwerty layout when I’m playing some
games and the bépo layout most of the time. I’ll use the command
~switch-layout~ defined above.
