Here's what happened:
My `emacs.glinux` derivation relies on gLinux `/usr/bin/emacs`, and Google
recently published version 27, so all corporate machines (i.e. this laptop)
switched from Emacs 26 to Emacs 27 overnight.
However, my Nix derivation was building all of the packages for Emacs 26, so
some packages were compatible while others weren't.
The Elisp package, `emr`, doesn't build for version 27, so I dropped it
altogether.
After switching my namespace separator from "/" to "-" the function,
`alist-get`, clashed (surprise!) with the pre-existing function, `alist-get`. As
I was struggling to debug my broken Emacs (it broke bc Emacs 27 rolled out), and
I changed the module name, "alist", to "al" attempting to defuse the issue.
I created a strangely named Elisp module, >.el, just to appease the CI gods. My
gut tells me that this is a desperate idea and fails the smell test. I'm pretty
eager to pass the linting phase of my Elisp CI, however, and I can always revert
this.
In order for this to scale, I need to solve two things:
1. Ad-hoc ignore fill-column rules for URLs and other exceptions.
2. Run Elisp flychecker without evaluating my Elisp code and firing its
side-effects.
I may regret this, but I delete Ocaml and ReasonML modules; I can alway restore
them thanks to Git.
Added more ceremony to other modules to appease the linting gods.
While I would like my CI build to closely resemble a non-CI build, supporting
the `all-the-icons-install-fonts` call is a low priority with a medium amount of
work required.
After my CI build for Emacs failed because the .local/share/wallpaper directory
was missing I had two options:
A. include .local/share/wallpaper in default.nix, which is cumbersome
B. drop support for managing system wallpaper from Emacs
I chose option B.
I'm starting to prefer the `inherit (builtins) path` pattern in my Nix
expressions. I know this is idiomatic, so even if I don't like it, I am trying
to learn to like it.
These were hard-coded as $HOME/BRIEFCASE, which won't work in CI, since CI runs
as the user buildkite-agent-socrates, whose $HOME directory doesn't exist.
TL;DR:
- Define runEmacsScript to emacs/default.nix for ci/pipelines/post-receive
- Write script.el to call (load init.el) and catch any errors
- Lint Elisp with gonewest818/elisp-lint
Also nice how Buildkite supports :gnu: emojis!
- Prefer prepending wpcDir, vendorDir to EMACSLOADPATH instead of using the
--directory flag
- Remove --load ${wpcPackageEl} because init.el calls (require 'wpc-package)
- Surround $@ in 2x-quotes
Following the advice of Domen's nix.dev anti-patterns, I'm preferring something
like...
```nix
builtins.path { path = /path/to/some.where; name = "some.where"; }
```
...to
```nix
/path/to/some/where
```
While the former is more verbose, it will fail to build when the path doesn't
exist, which I prefer.
I would prefer to define constants/briefcase in terms of `(getenv "BRIEFCASE")`
and assert that `(f-exists? (getenv "BRIEFCASE"))`, in one location:
constants.el
TL;DR:
- Prefer `(getenv "BRIEFCASE")` to `(f-expand "~/briefcase")`. I should audit my
Emacs for references to ~/briefcase and replace those calls with `getenv`.
- Remove calls setting <nixpkgs> and <depot> and rely exclusively on <briefcase>
- Prefer ~/nixpkgs-channels to ~/nixpkgs.
Notes:
- I need a better way of calling `home-manager switch` that resides within my
briefcase
Having `git secret hide` as a pre-commit hook doesn't make much sense to me. I
will detail why when/if I write a blog post on briefcase's secret mgt setup.
The problem is, if I change secrets.json and then run `git status`, I won't see
any pending changes. This is because secrets.json is gitignore'd. If I run `git
secret hide` everytime I save secrets.json, I can rest assured that my `git
status` will be consistent with any updates to secrets.json.
Anytime something before or during window-manager.el fails to evaluate,
I lose the ability to type, but I *can* still click.
@tazjin recommended that I use the mouse to cycle to the *Warnings*
buffer, which led me to another bug in a series of bugs that I'm
uncovering: ~/briefcase/org didn't exist.
A simple mistake like this should break my WM startup, so I decided to
remove most of my init hook logic.
Problem: dependency loading order
I originally assumed that keybindings.el was the first module to `require
'evil` because init.el shows:
```elisp
(require 'keybindings)
(require 'window-manager)
```
The problem is that keybindings.el calls `require 'window-manager` and
window-manager.el requires evil! I admit, I've created a bit of a birds nest for
myself.
A few thoughts:
- keybindings.el doesn't need to `require 'window-manager`. Fixed!
- window-manager.el shouldn't need to `require 'evil`. TODO...
While debugging some broken Emacs config, I ran Emacs in X, where for some
reason my PATH doesn't have my nix-env dependencies... because of this, when I
call `~/.nix-profile/bin/wpcarros-emacs` to start my Emacs, I saw warnings about
missing packages that I hadn't seen before. Nice!
In favor of keybindings.el!
Now I have:
- kbd.el: There are no keybindings in this file. It's just a library for working
with keybindings in Emacs.
- keybindings.el: (hopefully) all of my keybindings for EXWM, evil, etc.
In the spirit of Marie Kondo, I'm tidying up!
TL;DR:
- Prefer .envrc `use_nix` and delete all dir-locals.nix files
- Remove ~all references to <nixpkgs>, <unstable>, <depot> and prefer
referencing each with briefcase.third_party.{pkgs,unstable,depot}
- Delete nixBufferFromShell function since I was only using that in
dir-locals.nix files
Today @tazjin told me about Emacs's built-in project.el library, which he
recommended that I extend to support monorepo-specific tooling. It worked like a
charm!
Now when I press "<leader>f", it will resolve to either the nearest file named
default.nix or directory name .git.
After growing frustrated with doom-modeline's compatibility with my EXWM setup,
I decided to borrow @tazjin's setup, which I find to be much more appealing.
My current understanding of how computers deal with time:
- Modelling time is easy: use the number of seconds that have elapsed since the
Unix epoch.
- Display time is complicated. Which timezone should we use? Which format
string?
I think that glyphs look nice, but they subtley confuse Emacs's UI. In the case
of a two-character glyph condensing into one character's width, the fill-width
indicator -- correctly -- highlights the 81st character as red, but it looks
like it's erroneously highlighting the 80th.
Also when I want to create an anonymous function I type (), which condenses into
the unit character, and it's difficult to delete either the opening or the
closing parenthesis.
Overall I think glyphs are cute, but they're not worth the trouble.
After binary searching through my git history to restore my keyboard
functionality, I discovered the issue: I deleted the "Terminal" workspace, but I
did not remove the call to `(exwm/switch "Terminal")`, which silently prevented
EXWM from initializing.
I wish errors like this were noisier.
I created a google-stuff.el module months ago, but I have not needed to
use it much. Removing the google-stuff.el module and all of my
dependencies on it.
As I mentioned in the previous commit, I now use vterm.el as my primary
terminal. I wrote most of this Elisp when I first started using Emacs. I
know longer need it.
Before I switched to vterm.el, I used alacritty as my primary terminal.
I could not install alacritty on gLinux, so I switched to terminator.
When I was ricing my machine, I wanted my Emacs theme to change my
terminator theme. I never finished that project, and it is quite dusty
now.
