65Honestly, I should just change this "Original init.el" thing to a Makefile I can tangle in `config.org`, and track &#x2013; since it won't be overwritten or need any special `git` invocations to stop tracking it, I can edit it as I think about what would work best. I could also maybe give it more of a "cross-platform" vibe by installing, say, `straight.el` in the Makefile on Windows. One day &#x2026; 64 1. [Visual Fill Column](#org6f01971)

70After our first tangle, each time we edit `config.org` we want to go ahead and re-tangle our config. To that end, I've written `acdw/tangle-init`, which automatically tangles `config.org`. 69 1. [Emacs' files](#org6070b2c)

120While this is like, the *dumbest* way to do this, it's what I'm doing right now. I'm going to slap a TODO on here because I really should make it better &#x2013; like, `auth-sources` hooked into KeePassXC somehow&#x2026; ?

125# Early initiation
126
127Starting with version 27.1, Emacs loads `early-init.el` *before* `init.el`, setting up early stuff like package management, etc. Since I use an alternative package manager, I have to bootstrap it here.
128
129Of course, I also want to set some really early-on settings here too, like `load-prefer-newer` &#x2013; why not?

135## Increase the garbage collector
136
137Let's try to speed startup times by increasing the garbage collector's threshold while running init. Note the hook afterwards that restores it to a reasonable default.

148## Add more paths to the `exec-path`
149
150When using Windows (at work), I need to use the PortableGit installation I've downloaded, since I don't have Admin privileges.

156 (add-to-list 'exec-path path)))
157
158Elsewhere, I want to add a few more paths to the `exec-path` as well, since I store scripts in a couple of places at ~.
159
160 (dolist (path `(,(expand-file-name "bin"

168## Bootstrap [straight.el](https://github.com/raxod502/straight.el)
169
170So far, this is the best package manager I've used. It allows for *truly* declarative package management (if I don't specify a package here, it doesn't get loaded), easy installation from pretty much any source (as long as it's got a git repo), *and* it hooks into `use-package`!
171
172The one annoying thing is that this bootstrap code doesn't work on Windows for some reason. I'm too lazy to really try and figure out why, so when I need to bootstrap on Windows (pretty rare, TBH), I just [download the master-branch zip file](https://github.com/raxod502/straight.el/archive/master.zip) and extract it to `~/.emacs.d/straight/repos/`.
173
174 (defvar bootstrap-version)
175 (let ((bootstrap-file
176 (expand-file-name "straight/repos/straight.el/bootstrap.el"

185 (eval-print-last-sexp)))
186 (load bootstrap-file nil 'nomessage))
187
188
189## &#x2026; but first: override the definition of straight.el to use the `develop` branch
190
191For the KeePassXC bits later, I need the `develop` branch of straight, so I can pass a `:build` keyword. I can do this, but I have to override the recipe for `straight.el` itself. I do that here. For more information, see [the README](https://github.com/raxod502/straight.el#overriding-recipes).
192
193 (setq straight-repository-branch "develop")
194
195 (defvar bootstrap-version)
196 (let ((bootstrap-file
197 (expand-file-name "straight/repos/straight.el/bootstrap.el"

209
210## Use [use-package](https://jwiegley.github.io/use-package/)
211
212Like I said, `straight.el` hooks into `use-package` easily. These two lines get the latter to use the former by default.
213
214 (setq straight-use-package-by-default t)
215 (straight-use-package 'use-package)
216
217
218## Keep `~/.emacs.d` tidy with [no-littering](https://github.com/emacscollective/no-littering)
219
220I'll be honest &#x2013; I don't really notice this package. But I think that's the point. It keeps Emacs (and packages) from throwing files all over the place, so I have a clean `ls -l`. Since I want to run this code as early as possible, I use the `straight-use-package` form instead of `use-package`.
221
222 (straight-use-package 'no-littering)
223 (require 'no-littering)
224 126
225 127
226## Additional `use-package` keywords 128<a id="org9392b5d"></a>

133 (straight-use-package 'use-package)
230 134
231The `:custom-update` keyword lets me do this:
232 135
233 (use-package package 136<a id="orgc93ae09"></a>
234 :custom-update
235 (package-list '(1 2 3)))
236 137
237instead of this: 138### Extra use-package keywords
238 139
239 (use-package package 1401. :custom-update
240 :config
241 (add-to-list 'package-list '(1 2 3)))
242 141
243It's not &#x2026; perfect, but it's kind of nice. 142 (straight-use-package
143 '(use-package-custom-update

251## Setup [async](https://github.com/jwiegley/emacs-async)

253I thought this was included in Emacs at first, but it's not &#x2013; so we need to install and require it.

259# Macros

261
262## Customizing variables
263 149
264I like `use-package` a lot, but I don't like using those shims you see in a lot of other Emacs configs where they use `(use-package emacs)` forms and stuff like that &#x2013; it just feels dirty. Plus, `straight` gets confused about those packages sometimes. So, since I'm actually *configuring* Emacs in this Org file, which is nicely organized anyway, I can just set settings the old-school way. 150<a id="org7cae7fe"></a>
265 151
266Except. Using `setq` is actually *not* recommended any more, because `customize-set-variable` is more expressive and can include side-effects. However, not all settings are customizable, *and* `customize-set-variable` is like, way longer to type. So I've decided to write a little macro (my first!) to copy `use-package`'s `:custom` keyword, except &#x2026; *outside* `use-package`. I've called it `cuss`, because I have a terrible sense of humor. 152## Customize variables
267 153
268 (defmacro cuss (var val)
269 "Basically `use-package''s `:custom', but without using either."

402`smart-mode-line` comes with `rich-minority` for taking care of minor modes in the modeline, so I'm not going to *also* use `diminish` or anything. However, `rich-minority` has kind of a hinky way of adding modes to the whitelist, so I had to write my own function to do so. 261<a id="orgcdf874b"></a>
403 262

531## Completing-read niceties 354## Theme
532 355
533`completing-read` is Emacs's selection-narrowing-slash-completion framework thing. There's a bunch of packages for it, including `ido`, `icomplete`, `ivy`, and `helm`. I use raxod52's `selectrum` and others, which *extend* without *clobbering* existing Emacs functionality. Plus they seem to run faster, at least on Windows. 356 (use-package modus-themes

536### [selectrum](https://github.com/raxod502/selectrum) 359 :repo "protesilaos/modus-themes"
537 360 :branch "main")
538`selectrum` is the basic *sorting and selecting items from a list* functionality. It's a drop-in replacement for `ido` or the really basic tab-completion Emacs has for, say, `find-file`. 361 :custom

547`prescient` helps `selectrum` be more intelligent about sorting the candidates in a list &#x2013; it's in charge of the *filtering and sorting* bit of `completing-read` and friends. It has an algorithm that works well enough for me, though I keep hearing about [orderless](https://github.com/oantolin/orderless), enough to maybe try it as well sometime. 370 (modus-themes-no-mixed-fonts nil)

561`consult` is the newest package I have with this setup, and it kind of brings the `selectrum` experience up to par with `ivy`'s &#x2013; it provides functions that list, say, recently used files *alongside* buffers, allow you to search lines and go to them, etc. It seems pretty nice so far. 384 :custom-face

728## Auto-saves with [super-save](https://github.com/bbatsov/super-save)

730The default `auto-save` functionality isn't &#x2026; *enough* for me. I want to *actually* save the files, and I don't care about `#file#` stuff. So &#x2026; I use this package.

Hell, even Windows Notepad correctly reads UNIX files nowadays (though of course you can't configure it to *save* the files in UNIX-mode). However, since Emacs is ~40 years old, it has a billion different ways to set encodings. This is my best attempt at setting everything up how I want it.

1592I use KeePassXC, and I'd *like* to use KeePassXC to get passwords and stuff at home. So I'm trying this library out, since the secret-tool integration isn't built into the KeePassXC on Void. If this doesn't work, looks like I'll have to become a packager 😜

1631Here's a wrapper script that'll start `emacs --daemon` if there isn't one, and then launche `emacsclient` on the arguments. I'd recommend installing with `ln -s emacsdc ~/.local/bin/` or something. Then you can set it as your `$EDITOR`!

1650## export org to ODT on Windows
1651
1652Windows doesn't have `zip` natively (though it *does* have `curl` &#x2013; go figure!), so the ODT export for Org-mode won't work. There *is* a [StackOverflow discussion](https://stackoverflow.com/questions/8625306/org-mode-zip-needed-how-to-over-come) that mentions `p7zip` and a possible batch file, but I couldn't get that to work with a little testing. It might need more work.
1653
1654Something that *did* work was downloading `zip.exe` from [Info-ZIP](http://infozip.sourceforge.net/), and placing it somewhere in `exec-path` &#x2013; though of course, *then* you need `unzip.exe`, apparently in the same folder. Git Portable ships with `unzip.exe`, for example, but even though it's in `exec-path`, org-export threw an error unless `zip` and `unzip` were in the *same* folder.
1655 896
1656So I might either (a) have to set up computers in this way when I use new ones, or (b) include both `zip.exe` and `unzip.exe` in *this* Git repo, or &#x2026; something else. A true quandry.
