2515304c77 Prefer eval to source for direnv in config.fish
Calling `source` on `(direnv hook fish)` was creating startup problems with
fish. These problems leaked into a few of my Emacs file-searching commands as
well, which was pretty irritating for awhile. I'm still unsure of the
differences between `eval` and `source`. I'm moving on for now.

fac128f00c Debug xrandr integration to support 4k monitor
Two things:
1. I'm unsure if what I previously committed ever worked because the arguments
to `string/format` were flipped.
2. I'm unsure why my screen devices are sometimes eDP-1 and eDP1.

Perhaps expect more commits as this becomes more clear to me.

5a60ab886e Reset the custom-file path for Emacs
I temporarily set it to /tmp/custom.el while I was in the midst of Nixifying my
Emacs setup. Since I'm not Nixified at the moment, I'm reverting this, so that
Emacs doesn't ask me the same questions about loading themes every day.

ae75a9df9c Configure deadgrep
Configuring deadgrep to do a number of things:
1. Set `deadgrep--context` to see more context "after" in the output.
2. Define `deadgrep/dwim` to use a region if one is present; otherwise just
   behave as `deadgrep`.

Warning: This commit relies on a patch I made to deadgrep: supporting the
`deadgrep--additional-flags`.

71c24104eb Refactor MRU EXWM workspace using cycle/focus-previous!
Instead of consuming `cycle/previous-focus`, define a function
`cycle/focus-previous!` that "focuses" the element at `previous-index` and
returns that element.

This function greatly simplified the code in window-manager.el and eliminated
the unnecessary `exwm/previous-workspace` variable that was managing the state.

b52d210b9b Support cycle/previous-focus
Define a `cycle/previous-focus` function that returns the item that was
previously "focused" in the cycle. This is helpful for toggling back-and-forth
between buffers and EXWM workspaces for example without needing to define ad-hoc
variables to support it.

Also: Adds tests to cycle.el.

Also: Prefers `struct/set!` instead of `setf`. See the previous commit's message
for more information about that preference.

ef881e059b Prefer struct/set! to setf
I originally tried using `struct/set` instead of `setf`, which I had forgotten
was the *immutable* version of `struct/set!`. When this didn't work, I reverted
to `setf`. After a good night's sleep and with a fresh set of eyes, I dug into
the issue and discovered that `struct/set!` was what I wanted the whole.

I am curious now about `struct/update` versus `struct/update!`; shouldn't the
former be immutable and the latter be mutable? I'll save that investigation for
a later date.

271e7f9561 Support functions for navigating buffer caches
I've wanted an MRU/LRU sort of my "source code buffers" in Emacs. This commit
support three ways for working with a cache of source code buffers.

So first, what's a source code buffer? Well it isn't a buffer like *Messages*;
we can call these "Emacs-generated" buffers for convenience. Other problematic
buffers are buffers like `magit-status` and `dired-mode` and `erc` buffers.

I added some predicates for querying buffers for their major modes.

Supporting three KBDs for quickly accessing these functions:
1. <SPC><SPC> Toggle previous buffer
2. <SPC>b     Use ivy to fuzzily search source code buffers
3. C-{f,b}    Cycle {forwards,backwards} through the source code buffer cache.

2c03651483 Support KBDs for quickly editing common dotfiles
I had forgotten that I defined <SPC>J. Maybe I should switch to using Hydras or
transient mode to improve the discoverability of my own setup... well in the
spirit of support things that I will likely forget, here's a new KBD for editing
config files in the `~/.config` directory.

of the `find-file` calls I have with long path names. This DRYs things up as
well so that the path can be changed without breaking many other things.

6e77fc7978 Revert Nixified Emacs configuration
I attempted to Nixify my Emacs over winter break. I made some meaningful
progress, but not enough progress to use my Nixified Emacs setup. Since Emacs is
my primary editor and my window manager at work and at home, having a partially
baked setup is untenable at the moment.

Reverting these changes so that I can get on with my work, but checking them in
so that I can pick up where I left off one day.

069ca63082 WIP: Nixify Emacs setup
The things that I dislike about this setup are:
1. `xref-find-definitions` takes me to `/nix/store`, which is a read-only
version of the source code, so I cannot edit it, which doesn't feel lispy.

2. I need to rebuild the derivation when I change something, which also doesn't
feel lispy.

There are ways to circumvent both of these drawbacks, but for now, I'm checking
this in only to later revert it.

8d00a456a0 Beging work to port f.el to Haskell
This is a work-in-progress. I'd like to add a README to this project to explain
my intention. The goal, roughly, is to port Elisp's fantastic f.el module to
Haskell. I consider Haskell APIs to be useful but somewhat sloppily designed. In
the same spirit as Elixir wrapping Erlang APIs, many of the functions I intend
to define will simply wrap existing Haskell APIs, but with a hopefully cleaner
API that I find more intuitive.

d4d8397e5f Add InterviewCake.com examples
Adds some of the code I generated while studying for a role transfer at Google
using the fantastic resource, InterviewCake.com. This work predates the
mono-repo.

I should think of ways to DRY up this code and the code in
crack_the_coding_interview, but I'm afraid I'm creating unnecessary work for
myself that way.

f182410fd2 Support Freenode IRC
Previously my ERC setup just supported Google's internal IRC. Now I have
Freenode for things like #nixos, #emacs.

This complicated my KBDs for cycling through IRC channels since certain channels
only exist on certain servers. To remedy this, I introduced a temporary solution
that looks up the server given a particular channel. This isn't ideal, but it
works for now.

5785a5d126 Support prelude/start-process
If you refer to the previous commit where I change shell-command usages to
start-process function calls, you'll see the rationale for why I prefer
start-process.

This commit introduces a more ergonomic API for start-process that fits most of
my current use-cases of it. This cleans up the code. I have introduced a bug in
the way that I'm tokenizing the COMMAND value. I've tracked that with a
TODO. For now it only affects the `xmodmap -e '<command-string>'` calls, which
isn't too disruptive.

5fbe860b95 Prefer start-process to shell-command
Without doing any benchmarking (break this naughty habit), I'm preferring to
call `start-process` instead of `shell-command` in my `wallpaper/set`
function. I noticed that the `shell-command` call was unnecessarily polluting my
`pstree` call when I debugging my randomly changing wallpaper bug.

I'm mostly likely going to change a few more `shell-command` calls to prefer
`start-process`.

67f060d6f9 Temporarily disable flycheck
TL;DR:
Problem: I ran into a bug where my computer wallpaper was changing every five
seconds whenever my init.el file was open and I was typing in it.

Short-term solution: Disable flycheck.

Long-term solution: Disable flycheck just for Elisp or just for init.el in
Elisp.

Post Mortem:
Warning: If you have flycheck-emacs-lisp-initialize-packages set to auto or
really anything other than nil, than the emacs-lisp flycheck-checker will spin
up a new Emacs instance, and evaluate all of the Elisp in init.el.

Why does this matter? Well, if like me, you have code anywhere in your
init.el (and any files downstream from init.el), that code will get evaluated
not just twice. But countless times... tens, hundreds, w/e. So... while you
might think you have code that is just running at startup this code will be
called incessantly.

As a dramatic, contrived example, if you had something like...

```elisp
(bank/send :amount 100 :to "wpcarro@gmail.com")
```

...anywhere in that your init.el would evaluate, you may end up sending
wpcarro@gmail.com millions of dollars. To make debugging this problem a bit more
complicated is that because this runs in a separate Emacs instance, you can't do
something like...

```elisp
(defvar already-evaluated? nil)
(unless already-evaluated? (bank/send :amount 100 :to "wpcarro@gmail.com"))
(setq already-evaluated? t)
```

...since the `already-evaluated?` variable will be local to the Emacs
instance. So if you needed a mechanism to ensure code like this runs only once,
you would need a way to share this semaphore across Emacs instances --
e.g. writing to and reading from disk.
