Why didn't I configure this earlier? For years, my workflow involved checking a
buffer's major mode and then extending that major-mode's hook. Confusingly (to
me), the `major-mode` for `COMMIT_EDITMSG` is `text-mode`, and I didn't want to
disable `company-mode` for *all* `text-mode` buffers, which is what the
following would have done:
```elisp
(add-hook 'text-mode-hook (lambda () (company-mode -1))
```
Thankfully I recently invested some time into learning more about Emacs's
offline help system, `Info-mode`, so -- putting that knowledge to work -- I ran
`info-apropos` and searched "magit commit". After ~5 minutes of reading I knew
the recommended way of configuring this was to modify `git-commit-setup-hook`.
How validating!
My modeline was displaying the local time (not UTC time) and appending the UTC
timezone offset, which was confusing me.
When it was `00:03` in London, my modeline would read `00:03+01`. One way of
interpreting this is that it's `00:03` in London and the `+01` is a reminder
that I'm one hour ahead of UTC. However, I was reading it as though it was
`00:03` UTC and thus `01:03` in London.
I had to set `display-time-string-forms` instead of `display-time-string` to
pass the `t` argument to the `ZONE` parameter to indicate that I'd prefer to use
UTC time and not local time when expanding the variables.
I was previously relying on the variable `server-process` being set, but this
only resulted in false-negatives and broken initializations. This should make my
Emacs initialization more stable.
Since I'm calling `(require 'general)` in `wpc-package.el`, which gets called at
the beginning of my `init.el` file, all sub-modules have `general`. I originally
wanted this, but I'm beginning to rethink that preference.
After `script.el` broke my CI because of a missing `general` dependency, I'm
fixing it for `buffer.el` and all other modules that consume `general`.
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.
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.
I would prefer to define constants/briefcase in terms of `(getenv "BRIEFCASE")`
and assert that `(f-exists? (getenv "BRIEFCASE"))`, in one location:
constants.el
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.
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.
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 I removed the `(server-start)` call when I was debugging some EXWM
issues. I have stabilized my configuration considerably since then, and I'd like
to use the Emacs server.
