#+BEGIN_QUOTE
Let us change our traditional attitude to the construction of programs:
Instead of imagining that our main task is to instruct a computer what to do,
let us concentrate rather on explaining to human beings what we want a
computer to do. --- Donald Knuth

* Intro
Customising an editor can be very rewarding ... until you have to leave it.
For years I have been looking for ways to avoid this pain.
2020-02-03 18:16:07 +00:00
Then I discovered [[https://github.com/cknadler/vim-anywhere ][vim-anywhere ]], and found that it had an emacs companion,[[https://github.com/zachcurry/emacs-anywhere][
2020-01-20 18:08:07 +00:00
emacs-anywhere]]. To me, this looked most attractive.
Separately, online I have seen the following statement enough times I think it's a catchphrase
#+BEGIN_QUOTE
Redditor1: I just discovered this thing, isn't it cool.
Redditor2: Oh, there's an emacs mode for that.
#+END_QUOTE
I tried out the =spacemacs= distribution a bit, but it wasn't quite to my liking.
Then I heard about =doom emacs= and thought I may as well give that a try.
TLDR; it's great.
Now I've discovered the wonders of literate programming, and am becoming more
settled by the day. This is my config.
2020-01-03 14:33:36 +00:00
* Rudimentary configuration
2020-02-03 05:28:15 +00:00
Make this file run (slightly) faster with lexical binding (see [[https://nullprogram.com/blog/2016/12/22/ ][this blog post ]]
for more info).
#+BEGIN_SRC emacs-lisp
;;; config.el -*- lexical-binding: t; -* -
#+END_SRC
2020-01-03 14:33:36 +00:00
** Personal Information
It's useful to have some basic personal information
#+BEGIN_SRC emacs-lisp
(setq user-full-name "tecosaur"
user-mail-address "tecosaur@gmail.com")
#+END_SRC
Apparently this is used by ~GPG~ , and all sorts of other things.
** Better defaults
*** Simple settings
Browsing the web and seeing [[https://github.com/angrybacon/dotemacs/blob/master/dotemacs.org#use-better-defaults ][angrybacon/dotemacs ]] and comparing with the values
shown by =SPC h v= and selecting what I thought looks good, I've ended up adding the following:
#+BEGIN_SRC emacs-lisp
(setq-default
delete-by-moving-to-trash t ; Delete files to trash
tab-width 4 ; Set width for tabs
uniquify-buffer-name-style 'forward ; Uniquify buffer names
window-combination-resize t ; take new window space from all other windows (not just current)
x-stretch-cursor t) ; Stretch cursor to the glyph width
2020-02-02 18:21:19 +00:00
(setq undo-limit 80000000 ; Raise undo-limit to 80Mb
2020-03-04 15:27:08 +00:00
evil-want-fine-undo t ; By default while in insert all changes are one big blob. Be more granular
2020-03-18 04:07:19 +00:00
auto-save-default t ; Nobody likes to loose work, I certainly don't
inhibit-compacting-font-caches t) ; When there are lots of glyphs, keep them in memory
2020-01-09 18:00:31 +00:00
2020-01-03 14:33:36 +00:00
(delete-selection-mode 1) ; Replace selection when inserting text
(display-time-mode 1) ; Enable time in the mode-line
2020-01-09 18:04:48 +00:00
(display-battery-mode 1) ; On laptops it's nice to know how much power you have
2020-01-03 14:33:36 +00:00
(global-subword-mode 1) ; Iterate through CamelCase words
#+END_SRC
*** Fullscreen
I also like the idea of fullscreen-ing when opened by ~emacs~ or the ~.desktop~ file.
#+BEGIN_SRC emacs-lisp
(if (eq initial-window-system 'x) ; if started by emacs command or desktop file
(toggle-frame-maximized)
(toggle-frame-fullscreen))
#+END_SRC
*** Auto-customisations
By default changes made via a customisation interface are added to =init.el= .
I prefer the idea of using a separate file for this. We just need to change a
setting, and load it if it exists.
#+BEGIN_SRC emacs-lisp
2020-02-26 12:50:01 +00:00
(setq-default custom-file (expand-file-name ".custom.el" doom-private-dir))
2020-01-03 14:33:36 +00:00
(when (file-exists-p custom-file)
(load custom-file))
#+END_SRC
2020-02-02 03:44:35 +00:00
*** Windows
I find it rather handy to be asked which buffer I want to see after splitting
the window. Let's make that happen.
First, we'll enter the new window
#+BEGIN_SRC emacs-lisp
(setq evil-vsplit-window-right t
evil-split-window-below t)
#+END_SRC
Then, we'll pull up ~ivy~
#+BEGIN_SRC emacs-lisp
(defadvice! prompt-for-buffer (&rest _)
:after '(evil-window-split evil-window-vsplit)
2020-02-09 15:16:25 +00:00
(+ivy/switch-buffer))
2020-02-02 03:44:35 +00:00
#+END_SRC
2020-01-29 12:46:48 +00:00
*** Buffer defaults
I'd much rather have my new buffers in ~org-mode~ than ~fundamental-mode~ , hence
#+BEGIN_SRC emacs-lisp
2020-02-17 08:18:45 +00:00
;; (setq-default major-mode 'org-mode)
2020-01-29 12:46:48 +00:00
#+END_SRC
2020-02-17 08:18:45 +00:00
For some reason this + the mixed pitch hook causes issues with hydra and so I'll
just need to resort to =SPC b o= for now.
2020-01-03 14:33:36 +00:00
** Doom configuration
*** Visual Settings
**** Font Face
'Fira Code' is nice, and 'Overpass' makes for a nice sans companion. We just need to
fiddle with the font sizes a tad so that they visually match.
#+BEGIN_SRC emacs-lisp
2020-01-29 12:37:14 +00:00
(setq doom-font (font-spec :family "Fira Code" :size 22)
2020-01-09 17:52:29 +00:00
doom-big-font (font-spec :family "Fira Code" :size 36)
2020-01-29 12:37:14 +00:00
doom-variable-pitch-font (font-spec :family "Overpass" :size 24))
2020-01-03 14:33:36 +00:00
#+END_SRC
**** Theme
~doom-one~ is nice and all, but I find the ~vibrant~ variant nicer.
#+BEGIN_SRC emacs-lisp
(setq doom-theme 'doom-vibrant)
#+END_SRC
However, by default ~red~ text is used in the ~modeline~ , so let's make that orange
so I don't feel like something's gone /wrong/ when editing files.
#+BEGIN_SRC emacs-lisp
(custom-set-faces!
'(doom-modeline-buffer-modified :foreground "orange"))
#+END_SRC
**** Miscellaneous
Relative line numbers are fantastic for knowing how far away line numbers are,
then =ESC 12 <UP>= gets you exactly where you think.
#+BEGIN_SRC emacs-lisp
(setq display-line-numbers-type 'relative)
#+END_SRC
2020-02-06 17:11:35 +00:00
I'd like some slightly nicer default buffer names
#+BEGIN_SRC emacs-lisp
(setq doom-fallback-buffer-name "► Doom"
+doom-dashboard-name "► Doom")
#+END_SRC
2020-02-09 00:24:43 +00:00
There's a bug with the modeline in insert mode for org documents ([[https://github.com/seagle0128/doom-modeline/issues/300 ][issue ]]), so
2020-02-09 00:12:19 +00:00
#+BEGIN_SRC emacs-lisp
2020-02-16 05:24:03 +00:00
(custom-set-faces! '(doom-modeline-evil-insert-state :weight bold :foreground "#339CDB"))
2020-02-09 00:12:19 +00:00
#+END_SRC
2020-01-03 14:33:36 +00:00
*** Some helper macros
There are a few handy macros added by doom, namely
- ~load!~ for loading external ~.el~ files relative to this one
- ~use-package~ for configuring packages
- ~add-load-path!~ for adding directories to the ~load-path~ where ~emacs~ looks when
you load packages with ~require~ or ~use-package~
- ~map~ for binding new keys
To find more,
** Other things
*** Editor interaction
**** Mouse buttons
#+BEGIN_SRC emacs-lisp
2020-02-03 04:56:34 +00:00
(map! :n [mouse-8] #'better-jumper-jump-backward
:n [mouse-9] #'better-jumper-jump-forward)
2020-01-03 14:33:36 +00:00
#+END_SRC
2020-02-06 15:31:44 +00:00
*** Window title
I'd like to have just the buffer name, then if applicable the project folder
#+BEGIN_SRC emacs-lisp
(setq frame-title-format
'(""
"%b"
(:eval
(let ((project-name (projectile-project-name)))
(unless (string= "-" project-name)
2020-02-16 05:23:19 +00:00
(format (if (buffer-modified-p) " ◉ %s" " ● %s") project-name))))))
2020-02-06 15:31:44 +00:00
#+END_SRC
2020-03-27 04:20:42 +00:00
*** Splash screen
2020-03-28 15:19:41 +00:00
Emacs can render an image as the splash screen, and [[https://github.com/MarioRicalde ][@MarioRicalde ]] came up with a
cracker! He's also provided me with a nice emacs-style /E/ , which is good for
smaller windows. *@MarioRicalde* you have my sincere thanks, you're great!
[[file:misc/splash-images/blackhole-lines.svg ]]
By incrementally stripping away the outer layers of the logo one can obtain
quite a nice resizing effect.

This is where you install packages, by declaring them with the ~package!~
macro, then running ~doom refresh~ on the command line. You'll need to
restart Emacs for your changes to take effect! Or at least, run =M-x doom/reload= .
WARNING: Don't disable core packages listed in ~~/.emacs.d/core/packages.el~ .
Doom requires these, and disabling them may have terrible side effects.
*** Packages in MELPA/ELPA/emacsmirror
To install ~some-package~ from MELPA, ELPA or emacsmirror:
2020-02-16 08:13:42 +00:00
#+BEGIN_SRC emacs-lisp
2020-01-03 14:33:36 +00:00
(package! some-package)
#+END_SRC
*** Packages from git repositories
To install a package directly from a particular repo, you'll need to specify
a ~:recipe~ . You'll find documentation on what ~:recipe~ accepts [[https://github.com/raxod502/straight.el#the-recipe-format ][here ]]:
2020-02-16 08:13:42 +00:00
#+BEGIN_SRC emacs-lisp
2020-01-03 14:33:36 +00:00
(package! another-package
:recipe (:host github :repo "username/repo"))
#+END_SRC
If the package you are trying to install does not contain a ~PACKAGENAME.el~
file, or is located in a subdirectory of the repo, you'll need to specify
~:files~ in the ~:recipe~ :
2020-02-16 08:13:42 +00:00
#+BEGIN_SRC emacs-lisp
2020-01-03 14:33:36 +00:00

*** Disabling built-in packages
2020-01-03 14:33:36 +00:00
If you'd like to disable a package included with Doom, for whatever reason,
you can do so here with the ~:disable~ property:
2020-02-16 08:13:42 +00:00
#+BEGIN_SRC emacs-lisp
2020-01-03 14:33:36 +00:00
(package! builtin-package :disable t)
#+END_SRC
You can override the recipe of a built in package without having to specify
all the properties for ~:recipe~ . These will inherit the rest of its recipe
from Doom or MELPA/ELPA/Emacsmirror:
2020-02-16 08:13:42 +00:00
#+BEGIN_SRC emacs-lisp
2020-01-03 14:33:36 +00:00
(package! builtin-package :recipe (:nonrecursive t))
(package! builtin-package-2 :recipe (:repo "myfork/package"))
#+END_SRC
Specify a ~:branch~ to install a package from a particular branch or tag.
This is required for some packages whose default branch isn't 'master' (which
our package manager can't deal with; see [[https://github.com/raxod502/straight.el/issues/279 ][raxod502/straight.el#279 ]])
2020-02-16 08:13:42 +00:00

Because of the /[[https:/ /github.com/commonmark/commonmark-spec/wiki/markdown-flavors][lovely variety in markdown implementations]]/ there isn't actually
such a thing a standard table spec ... or standard anything really. Because
~org-md~ is a goody-two-shoes, it just uses HTML for all these non-standardised
elements (a lot of them). So ~ox-gfm~ is handy for exporting markdown with all the
features that GitHub has. Initialised in [[Exporting to GFM ]].

** Centaur Tabs
We want to make the tabs a nice, comfy size (~36~ ), with icons. The modifier
marker is nice, but the particular default Unicode one causes a lag spike, so
let's just switch to an ~o~ , which still looks decent but doesn't cause any
issues.
A 'active-bar' is nice, so let's have one of those. If we have it ~under~ needs us to
turn on ~x-underline-at-decent~ though. For some reason this didn't seem to work
inside the ~(after! ... )~ block ¯\_(ツ)_ /¯.
Then let's change the font to a sans serif, but the default one doesn't fit too
well somehow, so let's switch to 'P22 Underground Book'; it looks much nicer.

It's also nice to change the character used for collapsed items (by default ~…~ ),
I think ~▾~ is better for indicating 'collapsed section'.
and add an extra ~org-bullet~ to the default list of four.

We can either render from a ~dvi~ or ~pdf~ file, so let's benchmark ~latex~ and
~pdflatex~ .
| ~latex~ time | ~pdflatex~ time |
|------------+---------------|
| 135±2 ms | 215±3 ms |
2020-02-03 05:01:57 +00:00
On the rendering side, there are two ~.dvi~ -to-image convertors which I am
2020-02-17 02:26:51 +00:00
interested in: ~dvipng~ and ~dvisvgm~ . Then with the a ~.pdf~ we have ~pdf2svg~ .
For inline preview we care about speed, while for exporting we care about file
size and preffer a vector graphic.
Using the above latex expression and benchmarking lead to the following results:
| ~dvipng~ time | ~dvisvgm~ time | ~pdf2svg~ time |
|-------------+--------------+--------------|
| 89±2 ms | 178±2 ms | 12±2 ms |
Now let's combine this to see what's best
| Tool chain | Total time | Resultant file size |
|--------------------+------------+---------------------|
| ~latex~ + ~dvipng~ | 226±2 ms | 7 KiB |
| ~latex~ + ~dvisvgm~ | 392±4 ms | 8 KiB |
| ~pdflatex~ + ~pdf2svg~ | 230±2 ms | 16 KiB |
2020-02-03 05:01:57 +00:00
So, let's use ~dvipng~ for previewing LaTeX fragments in-emacs, but ~dvisvgm~ for [[
Exporting to HTML][LaTeX Rendering]].
2020-02-17 02:26:51 +00:00
/Unfortunately: it seems that svg sizing is annoying ATM, so let's actually not do this right now./

** hledger
~ledger-mode~ is great and all, but ~hledger~ seems to be more actively maintained.
For example, from 2018--2020, the most prolific contributor to ~ledger~ produced
31 commits. For ~hledger~ this statistic is 1800 commits. In addition, over the
last decade, ~ledger~ seems to have lost steam, while ~hledger~ seems as actively
developed as ever. From this basic comparison ~hledger~ looks to have a more
promising outlook. It also has a few extra nicities that ~ledger~ doesn't, but is
2020-02-17 08:16:56 +00:00
a little slower (~haskell~ vs. ~c++~ ).
2020-02-03 05:04:00 +00:00
Since this uses the same format, and ~ledger-mode~ is well integrated into emacs,
2020-02-17 08:16:56 +00:00
and produced by John Wiegley --- author of ~ledger~ and current Emacs maintainer
2020-02-03 05:04:00 +00:00
--- using this seems like a good idea. Thankfully we can, with a little modification.

will do it's own line wrapping, hence we /only/ want to use visual line wrapping. No hard stuff.
