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.
