* About this config
This is my personal Doom Emacs config. Doom Emacs is a distribution of Emacs
that uses the "evil" keybindings (Vim keybindings) and includes a number of nice
extensions and a bit of configuration out of the box. I am maintaining this
config not just for myself, but also for those that want to explore some of what
is possible with Emacs. I will add a lot of examples of plugins and settings,
some of them I may not even use personally. This config is a fork of
DistroTube's config.
* Beacon
Never lose your cursor. When you scroll, your cursor will shine! This is a
global minor-mode. Turn it on everywhere with:
#+begin_src emacs-lisp
(beacon-mode 1)
#+end_src
* Bookmarks and buffers
Doom Emacs uses 'SPC b' for keybindings related to bookmarks and buffers.
** Bookmarks
Bookmarks are somewhat like registers in that they record positions you can jump
to. Unlike registers, they have long names, and they persist automatically from
one Emacs session to the next. The prototypical use of bookmarks is to record
where you were reading in various files.
#+BEGIN_SRC emacs-lisp
(map! :leader
(:prefix ("b". "buffer")
:desc "List bookmarks" "L" #'list-bookmarks
:desc "Save current bookmarks to bookmark file" "w" #'bookmark-save))
#+END_SRC
** Buffers
Regarding /buffers/, the text you are editing in Emacs resides in an object called
a /buffer/. Each time you visit a file, a buffer is used to hold the file’s text.
Each time you invoke Dired, a buffer is used to hold the directory listing.
/Ibuffer/ is a program that lists all of your Emacs /buffers/, allowing you to
navigate between them and filter them.
| COMMAND | DESCRIPTION | KEYBINDING |
|-----------------+----------------------+------------|
| ibuffer | Launch ibuffer | SPC b i |
| kill-buffer | Kill current buffer | SPC b k |
| next-buffer | Goto next buffer | SPC b n |
| previous-buffer | Goto previous buffer | SPC b p |
| save-buffer | Save current buffer | SPC b s |
** Global Auto Revert
A buffer can get out of sync with respect to its visited file on disk if that
file is changed by another program. To keep it up to date, you can enable Auto
Revert mode by typing M-x auto-revert-mode, or you can set it to be turned on
globally with 'global-auto-revert-mode'. I have also turned on Global Auto
Revert on non-file buffers, which is especially useful for 'dired' buffers.
#+begin_src emacs-lisp

* Calendar
Let's make a 12-month calendar available so we can have a calendar app that,
when we click on time/date in xmobar, we get a nice 12-month calendar to view.

* Dired
Dired is the file manager within Emacs. Below, I setup keybindings for image
previews (peep-dired). Doom Emacs does not use 'SPC d' for any of its
keybindings, so I've chosen the format of 'SPC d' plus 'key'.

* Doom theme
Setting the theme to doom-gruvbox. To try out new themes, I set a keybinding for
counsel-load-theme with 'SPC h t'.
#+BEGIN_SRC emacs-lisp
(setq doom-theme 'doom-gruvbox)
(map! :leader
:desc "Load new theme" "h t" #'counsel-load-theme)
#+END_SRC
* Emojis
Emojify is an Emacs extension to display emojis. It can display github style
emojis like :smile: or plain ascii ones like :).
#+begin_src emacs-lisp
(use-package emojify
:hook (after-init . global-emojify-mode))
#+end_src
* Evaluate elisp expressions
Changing some keybindings from their defaults to better fit with Doom Emacs, and
to avoid conflicts with my window managers which sometimes use the control key
in their keybindings. By default, Doom Emacs does not use 'SPC e' for anything,
so I choose to use the format 'SPC e' plus 'key' for these (I also use 'SPC e'
for 'eww' keybindings).
| COMMAND | DESCRIPTION | KEYBINDING |
|-----------------+----------------------------------------------+------------|
| eval-buffer | /Evaluate elisp in buffer/ | SPC e b |
| eval-defun | /Evaluate the defun containing or after point/ | SPC e d |
| eval-expression | /Evaluate an elisp expression/ | SPC e e |
| eval-last-sexp | /Evaluate elisp expression before point/ | SPC e l |
| eval-region | /Evaluate elisp in region/ | SPC e r |
#+Begin_src emacs-lisp
(map! :leader
(:prefix ("e". "evaluate/EWW")
:desc "Evaluate elisp in buffer" "b" #'eval-buffer
:desc "Evaluate defun" "d" #'eval-defun
:desc "Evaluate elisp expression" "e" #'eval-expression
:desc "Evaluate last sexpression" "l" #'eval-last-sexp
:desc "Evaluate elisp in region" "r" #'eval-region))
#+END_SRC
* Eww
EWW is the Emacs Web Wowser, the builtin browser in Emacs. Below I set urls to
open in a specific browser (eww) with browse-url-browser-function. By default,
Doom Emacs does not use 'SPC e' for anything, so I choose to use the format 'SPC
e' plus 'key' for these (I also use 'SPC e' for 'eval' keybindings). I chose to
use 'SPC s w' for eww-search-words because Doom Emacs uses 'SPC s' for 'search'
commands.
#+BEGIN_SRC emacs-lisp
(setq browse-url-browser-function 'eww-browse-url)
(map! :leader
:desc "Search web for text between BEG/END"

#+END_SRC
* Fonts
Settings related to fonts within Doom Emacs:
+ 'doom-font' -- standard monospace font that is used for most things in Emacs.
+ 'doom-variable-pitch-font' -- variable font which is useful in some Emacs plugins.
+ 'doom-big-font' -- used in doom-big-font-mode; useful for presentations.
+ 'font-lock-comment-face' -- for comments.
+ 'font-lock-keyword-face' -- for keywords with special significanclike 'setq' in elisp.
#+BEGIN_SRC emacs-lisp
(setq doom-font (font-spec :family "mononoki Nerd Font" :size 15)

#+END_SRC
* Imenu
Imenu produces menus for accessing locations in documents, typically in the
current buffer. You can access the locations using an ordinary menu (menu bar or
other) or using minibuffer completion, or you can install 'imenu-list' and have
the imenu displayed as a vertical split that you can toggle show/hide.
| COMMAND | DESCRIPTION | KEYBINDING |
|-------------------------+----------------------------------+------------|
| counsel-imenu | /Menu to jump to places in buffer/ | SPC s i |
| imenu-list-smart-toggle | /Toggle imenu shown in a sidebar/ | SPC t i |
#+BEGIN_SRC emacs-lisp

:desc "Toggle imenu shown in a sidebar" "i" #'imenu-list-smart-toggle))
#+END_SRC
* Insert date
Some custom functions to insert the date. The function 'insert-todays-date' can
be used one of three different ways: (1) just the keybinding without the
universal argument prefix, (2) with one universal argument prefix, or (3) with
two universal argument prefixes. The universal argument prefix is 'SPC-u' in
Doom Emacs (C-u in standard GNU Emacs). The function 'insert-any-date' only
outputs to one format, which is the same format as 'insert-todays-date' without
a prefix.
| COMMAND | EXAMPLE OUTPUT | KEYBINDING |
|-----------------------+---------------------------+-----------------------|
| dt/insert-todays-date | Friday, November 19, 2021 | SPC i d t |
| dt/insert-todays-date | 11-19-2021 | SPC u SPC i d t |
| dt/insert-todays-date | 2021-11-19 | SPC u SPC u SPC i d t |
| dt/insert-any-date | Friday, November 19, 2021 | SPC i d a |
#+begin_src emacs-lisp

(require 'calendar)
(defun dt/insert-any-date (date)

#+end_src
* Ivy
Ivy is a generic completion mechanism for Emacs.
** Ivy-posframe
Ivy-posframe is an ivy extension, which lets ivy use posframe to show its
candidate menu. Some of the settings below involve:
+ ivy-posframe-display-functions-alist -- sets the display position for specific
programs
+ ivy-posframe-height-alist -- sets the height of the list displayed for
specific programs
# Available functions (positions) for 'ivy-posframe-display-functions-alist'
+ ivy-posframe-display-at-frame-center
+ ivy-posframe-display-at-window-center
+ ivy-posframe-display-at-frame-bottom-left
+ ivy-posframe-display-at-window-bottom-left
+ ivy-posframe-display-at-frame-bottom-window-center
+ ivy-posframe-display-at-point
+ ivy-posframe-display-at-frame-top-center
=NOTE:= If the setting for 'ivy-posframe-display' is set to 'nil' (false),
anything that is set to 'ivy-display-function-fallback' will just default to
their normal position in Doom Emacs (usually a bottom split). However, if this
is set to 't' (true), then the fallback position will be centered in the window.
#+BEGIN_SRC emacs-lisp
(setq ivy-posframe-display-functions-alist
'((swiper . ivy-posframe-display-at-point)

(ivy-posframe-mode 1) ; 1 enables posframe-mode, 0 disables it.
#+END_SRC
** Ivy keybindings
By default, Doom Emacs does not use 'SPC v', so the format I use for these
bindings is 'SPC v' plus 'key'.
#+BEGIN_SRC emacs-lisp
(map! :leader
(:prefix ("v" . "Ivy")
:desc "Ivy push view" "v p" #'ivy-push-view
:desc "Ivy switch view" "v s" #'ivy-switch-view))
#+END_SRC
* Line settings
I set comment-line to 'SPC TAB TAB' which is a rather comfortable keybinding for
me on my ZSA Moonlander keyboard. The standard Emacs keybinding for
comment-line is 'C-x C-;'. The other keybindings are for commands that toggle
on/off various line-related settings. Doom Emacs uses 'SPC t' for "toggle"
commands, so I choose 'SPC t' plus 'key' for those bindings.
| COMMAND | DESCRIPTION | KEYBINDING |
|--------------------------+-------------------------------------------+-------------|
| comment-line | /Comment or uncomment lines/ | SPC TAB TAB |
| hl-line-mode | /Toggle line highlighting in current frame/ | SPC t h |

* Minimap
A minimap sidebar displaying a smaller version of the current buffer on either
the left or right side. It highlights the currently shown region and updates its
position automatically. Be aware that this minimap program does not work in Org
documents. This is not unusual though because I have tried several minimap
programs and none of them can handle Org.

* Neotree
Neotree is a file tree viewer. When you open neotree, it jumps to the current
file thanks to neo-smart-open. The neo-window-fixed-size setting makes the
neotree width be adjustable. Doom Emacs had no keybindings set for neotree.
Since Doom Emacs uses 'SPC t' for 'toggle' keybindings, I used 'SPC t n' for
toggle-neotree.

* Open specific files
Keybindings to open files that I work with all the time using the find-file
command, which is the interactive file search that opens with 'C-x C-f' in GNU
Emacs or 'SPC f f' in Doom Emacs. These keybindings use find-file
non-interactively since we specify exactly what file to open. The format I use
for these bindings is 'SPC =' plus 'key' since Doom Emacs does not use 'SPC ='.

adding (+journal +pretty +roam2) to the org section of my Doom Emacs init.el.

* Perspective
Perspective provides multiple named workspaces (or "perspectives") in Emacs,
similar to having multiple desktops in window managers like Awesome and XMonad.
Each perspective has its own buffer list and its own window layout, making it
easy to work on many separate projects without getting lost in all the buffers.
Switching to a perspective activates its window configuration, and when in a
perspective, only its buffers are available (by default). Doom Emacs uses 'SPC
some_key' for binding some of the perspective commands, so I used this binging
format for the perspective bindings that I created..
| COMMAND | DESCRIPTION | KEYBINDING |
|----------------------------+-------------------------------------+------------|
| persp-switch | Switch to perspective NAME | SPC DEL |

* Rainbow mode
Rainbox mode displays the actual color for any hex value color. It's such a
nice feature that I wanted it turned on all the time, regardless of what mode I
am in. The following creates a global minor mode for rainbow-mode and enables
it.

* Registers
Emacs registers are compartments where you can save text, rectangles and
positions for later use. Once you save text or a rectangle in a register, you
can copy it into the buffer once or many times; once you save a position in a
register, you can jump back to that position once or many times. The default
GNU Emacs keybindings for these commands (with the exception of
counsel-register) involves 'C-x r' followed by one or more other keys. I wanted
to make this a little more user friendly, and since I am using Doom Emacs, I
choose to replace the 'C-x r' part of the key chords with 'SPC r'.

* Splits
I set splits to default to opening on the right using 'prefer-horizontal-split'.
I set a keybinding for 'clone-indirect-buffer-other-window' for when I want to
have the same document in two splits. The text of the indirect buffer is always
identical to the text of its base buffer; changes made by editing either one are
visible immediately in the other. But in all other respects, the indirect
buffer and its base buffer are completely separate. For example, I can fold one
split but other will be unfolded.
#+BEGIN_SRC emacs-lisp

* Winner mode
Winner mode has been included with GNU Emacs since version 20. This is a global
minor mode and, when activated, it allows you to “undo” (and “redo”) changes in
the window configuration with the key commands 'SCP w <left>' and 'SPC w
<right>'.
#+BEGIN_SRC emacs-lisp

#+END_SRC
* Zap to char
Emacs provides a 'zap-to-char' command that kills from the current point to a
character. It is bound to 'M-z' in standard GNU Emacs but since Doom Emacs uses
'SPC' as its leader key and does not have 'SPC z' binded to anything, it just
makes since to use it for 'zap-to-char'. Note that 'zap-to-char' can be used
with the universal argument 'SPC u' to modify its behavior. Examples of
'zap-to-char' usage are listed in the table below:
| KEYBINDING | WHAT IS DOES |
|---------------------------+------------------------------------------------------------|
| SPC z e | deletes all chars to the next occurrence of 'e' |
| SPC u 2 SPC z e | deletes all chars to the second occurrence of 'e' |
| SPC u - SPC z e | deletes all chars to the previous occurrence of 'e' |
| SPC u -2 SPC z e | deletes all chars to the fourth previous occurrence of 'e' |
| SPC u 1 0 0 SPC u SPC z e | deletes all chars to the 100th occurrence of 'e' |
=TIP:= The universal argument (SPC u) can only take a single integer by default.
If you need to use a multi-digit number (like 100 in the last example in the
table above), then you must terminate the universal argument with another 'SPC
u' after typing the number.
'zap-up-to-char' is an alternative command that does not zap the char specified.
It is binded to 'SPC Z'. It can also be used in conjunction with the universal
argument 'SPC u' in similar fashion to the the 'zap-to-char' examples above.
=NOTE:= Vim (evil mode) has similar functionality builtin. You can delete to
the next occurrence of 'e' by using 'dte' in normal. To delete to the next
occurrence of 'e' including the 'e', then you would use 'dfe'. And you can
modify 'dt' and 'df' by prefixing them with numbers, so '2dte' would delete to
the second occurrence of 'e'.
