… sort of. Emacs apps will stuff all manner of transient state under
user-emacs-directory by default, so full XDG compliance would probably
involve customizing them all to instead use ~/.cache but 🤷
|
|
Obsoleted. While in there, rewrite to taste:
- could just switch to when-let*, but I hear and-let* is more
idiomatic for code that returns values; when(-let) OTOH denotes
side-effects.
- project-root (singular) has been available since 28, which is in
Debian stable. Good enough.
- I know about 𝓍-let*'s (VALUEFORM) shorthand now.
- “(string-trim-right root "/")”? 🤭

Probably handles 99% of the uses I've had for the substring style?
|
|
Chance met reading '(elisp) Process Information'.
|
|
The maintainers decided to disable Unicode symbols by default;
re-enable them.
Also fix the version check for Eglot and use-package.
|
|

The stuff about package-initialize is flat out wrong:
(a) package-initialize is _not_ called automatically at startup;
(b) for all that, customizations seem none the worse for wear.
'(elisp) Packaging Basics' suggests that Emacs does automatically call
'package-activate-all' (unless asked otherwise in the early init file)
so it's really not clear what that business with package-initialize
was about 🤷
Add some more up-to-date commentary regarding other topics.
|
|
Not sure why I thought this cross-reference "format" was a good idea.
Perhaps because it works even if 'calendar' is not loaded? OTOH C-x
C-e vomits the docstring to the echo area, so meh.

* .emacs (my/run-strip-newline): New escape hatch, to let my/run DTRT
most of the time and spare most callers the cognitive load.
(my/run): Heed it. Document.
(my/kill-command): New helper; meant for programmatic use where
arglists are manipulated as lists, and and no shell escaping is
required.
(my/kill-date, my/describe-revision): Use it.
(my/kill-shell): Document, to disambiguate with my/kill-command.
|
|
Comes up often enough, e.g. to add a stamp to a filename; probably was
the original motivation for my/kill-shell.
Gave a honest attempt at using a transient for this, but got bogged
down second-guessing whether I should define my arguments as
shorthands inside my transient-define-prefix form, or as dedicated
transient-define-argument forms; gave up while trying to figure out
whether the shorthand form could use transient-read-date.

IIUC the previous version ran customizations immediately during
expansion (ultimately expanding to the last customize-set-variable
value), instead of generating forms that would run those
customizations at appropriate times.
Guess I never run Emacs <29 😐
|
|
Also move more customizations to use-package forms.
|
|
Been using that for literal years at $DAYJOB; no idea why it's taken
me this long to port to my personal config.
|
|
It's probably more idiomatic to run a testcase you are developing in
your own session, using 'M-x ert' commands? I figure starting a fresh
Emacs cannot hurt.
|
|
Unhappy with those timestamps, but somewhat less unhappy than when I
started.
Also
* remove erc-fill-wrap: as mentioned in the comments, it causes
intempestive recentering;
* remove erc-notifications-mode; redundant with 'notifications' in
erc-modules.
|
|
Set shr-fill-text to nil; this automatically causes eww to enable
visual-line-mode.
For Gnus, the dance is a bit more involved. Not 100% happy with where
I landed, but at least I gave myself an escape hatch by rebinding C-c
d v in summary buffers.
Also,
* lift size restriction when fontifying citations: it mostly only ever
causes fontification failures when people review big patches,
* tweak header order slightly,
* align shr heading faces with eighters-title-* faces.
|
|
|
|
And finally get around to setting calendar-intermonth-text.
Re-implement the docstring's example using functions I actually
understand.
|
|
|
|
That package is unusual in that it requires… requiring it, in order
to activate its settings. So it's a good candidate for use-package's
:demand t.
It's also a good candidate because something changed in Emacs's Lisp
pretty-printing code, and now customizing anything changes how this
variable is serialized, generating a spurious diff. Can't wait to
have completely moved away from that auto-generated form.
|
|
* Remove provisions for Emacs<28.
* Move Magit command to my/magit-map.
|
|
|
|
Move Python settings to use-package. Tweak a couple of knobs while in
there.
|
|
* "Extra keys" are advertised for non-graphical configurations; as it
happens, they are also useful to provide substitutes for bindings
based on arrow keys.
* Speed commands are nice. Might tweak the predicate some day, but
the default is already useful.

Mostly to avoid icomplete jank (bug#40152).
Inspired by:
<https://www.scss.tcd.ie/~sulimanm/posts/default-emacs-completion.html>
Rationale for the customizations:
C-M- chord for navigation Because I found myself missing C-n/C-p in
a couple of situations.
auto-help 'visible The feedback is not as immediate as
icomplete, but it's good enough. Tried
'always, but there's a sit-for somewhere
that causes a weird pause if you happen to
RET before bringing up completions.
auto-select 'second-tab M-v? M-g M-c??
show-help nil "Click on a selection to select it" 😏
format 'one-column Where have you been all my life.
max-height 10 More often than not I'm typing something
inspired by the content from another
buffer, so limit how much
context *Completions* can hide.
auto-choose icomplete never clobbered the minibuffer
until I asked it to (with e.g. C-M-i).
Since C-u M-RET is a thing, keep
candidates off the minibuffer unless I
pull them in, in case I change my mind and
start typing something entirely different
from the currently highlighted candidate.

Puzzled by this problem I have with :hook. "(use-package) Hooks"
suggests that if package X defines function X-foo to be used by
package Y in Y-bar-hook, then the idiomatic thing to do is…
(use-package X
:hook ((Y-bar . X-foo)))
… but empirically, if Y.el contains…
(defcustom Y-bar-hook '(Y-quux Y-corge))
(add-hook 'Y-bar-hook #'Y-grault)
… then Y-bar-hook will be set to '(X-foo Y-grault): it will be missing
the functions added in the defcustom form.
Since add-hook does this:
(or (boundp hook) (set hook nil))
I am assuming that the problem happens when use-package runs X's :hook
additions before Y is loaded. No idea (a) if I can reproduce from -Q
(b) if this is a SNAFU from setting always-defer (c) if this could be
solved by sprinkling :after or :requires.

Recent ElDoc & Eglot developments have made the defaults much more
tolerable (the echo area height does not oscillate as much) &
useful (linter warnings are no longer preempted by symbol
documentation).
|
|
'cause why not.
|
|
|
|
* ponder magical "kill context so I can paste it into another app"
commands,
* remove obsolete Magit variables,
* make org-goto use the "path completion" UI,
* ponder better buffer names for some buffers.

Leave font-lock faces alone; just unset shell-font-lock-keywords.

show-paren-mode is not needed for Emacs≥28, but I still have stuff in
these dotfiles that purport to support older versions.
|
|
They've been sitting here unstaged for, like, ever.

Trying to get back the sense of sharp contrast I had before.
Snippets from *scratch* in case I need to recompute some of these:

(pcase-let ((`(,h1 ,s1 _) (apply 'color-rgb-to-hsl
(color-name-to-rgb c1)))
(`(_ _ ,l2) (apply 'color-rgb-to-hsl
(color-name-to-rgb c2))))
(message "hue %.3f with s %.3f l %.3f" h1 s1 l2)
(apply 'color-rgb-to-hex
`(,@(color-hsl-to-rgb h1 s1 l2) 2))))
(defun my/modus-rgb (key palette)
(let ((value (car (alist-get key palette))))
(if (stringp value)
value
(car (alist-get value palette)))))
(list-colors-display

FTR, things that I expect to need further tweaks and/or discussions
with Prot:
(a) no "version" command, so it's kind of hard to guess what we are
working with programmatically,
(b) preset palettes overrides are unavailable before loading the
themes, and we can't require 'modus-themes either; maybe the
manual should point out that users who want to use those presets
should (1) do that in :config (2) load the theme twice?
(c) lots of backgrounds look very light/saturated to me even in the
"faint preset": e.g. diff backgrounds, selected completion,
region, eldoc current argument.

Try as I might, I can't get my fingers to reach for underscores when
my brain is thinking of *equality signs.
|
|
I don't use any of the auto-deferring keywords; setting this shaves a
bit off my startup time (5s ↘ 3.2s).
|
|
This reverts commit d3e251ac8ac4ee953fe24234b4ff4755a185b494.
Will customize use-package-always-defer instead.
|
|
|
|
|
|
|
|
Also move it up, closer to Custom-related stuff.
|
|
Also update package list:
- account eglot and use-package being built-in
- add a couple of packages for Emacs development (elisp-benchmarks,
gnus-mock)
- remove paradox (most features now built into vanilla package.el)
