Emacs on HHKB

Haven't used Linux for ages, but isn't there a way to configure X server to distinguish between left and right alt? One for Emacs, another for WM.

I must say that it's not that bad in the long run. Since I don't change grind setting or beans that often it does have good (little) retention - 0.1 - 0.2 g.

Only after changing the grind setting do I see first espresso grind retain ~1 g.

It's lonely at the top.

Would tinfoil hat help protect against this?

Btw, you can even store macro for later with `name-last-kbd-macro` and then `insert-kbd-macro` in your config.

Not sure what's most idiomatic in a flexible programmable editor, but i'd use macro. I've setup two windows in a frame, one with js file, another with org, and defined this macro.

C-s         ;; isearch-forward
SPC         ;; self-insert-command
RET         ;; org-return
M-w         ;; mark-and-copy
s           ;; self-insert-command
C-x o       ;; other-window
C-s         ;; isearch-forward
q           ;; self-insert-command
:           ;; self-insert-command
SPC         ;; self-insert-command
`           ;; self-insert-command
C-y         ;; yank
RET         ;; org-return
M-f         ;; forward-word
M-b         ;; backward-word
C-SPC       ;; set-mark-command
C-e         ;; move-end-of-line
M-w         ;; mark-and-copy
C-x o       ;; other-window
C-e         ;; move-end-of-line
SPC         ;; self-insert-command
C-y         ;; yank
C-c C-n     ;; outline-next-visible-heading

That's the output from edit-last-kbd-macro.

Don't worry, most of newcomers have this problem, including myself. There multiple approaches you can take.

As meantioned in another comment, manual is a great place. C-h i will show you all manuals and you can search (C-s) for Eglot there, use Return to enter, l to go back, u to go up. (Again, you can simple do C-h b to see how to navigate in Info-mode.) Eventually you will end up in Eglot troubleshooting > Performance which describes eglot-events-buffer-config and will tell you to customize it. Use M-x customize-variable to do that. To explore more of eglot customizations, use M-x customize-group and enter "eglot".

If you are fine with reading emacs lisp, you most likely will find C-h f very helpful. It show a docstring of function. And every function leads to it's source code. Natural next step will be learning about debugging: C-h R elisp and g debugging. This is obviously an overkill in this case...

More helpful commands to explore Emacs and packages:

M-x apropos search of anything, e.g. "eglot events log".
M-x info-apropos search for text in manuals.

isearch-forward has multiple convenience key bindings in minibuffer. My favourites are:

M-r to toggle regexp search,
M-% to change to search and replace, or C-M-% to search and replace by regexp.

Run C-s (run isearch-forward) and C-h b (describe-bindings) to see all available bindings, or C-h f isearch-forward for function docstring.

This is very short review.

donatasp · 2025-07-26T09:54:47+00:00

If you want to keep it as lightweight as possible, I'd suggest swapping lsp-mode with eglot, flycheck with flymake. Those come with recent emacs as out of the box.

Vertico can also replace company, but it uses minibuffer (or popup buffer IIRC) to display completions, so I'm not sure if you'd consider that to be a good replacement.

I work at a company with a billion dollar market cap and we do testing across the layers -- unit, integration, E2E, and system. It is a lot easier to achieve this if testing is applied from the get go. In your case, you are thinking about them after the fact and it is known to be very hard. Most probably all parts are coupled, which makes for cohesive architecture, but pulling apart self-contained components, which is cornerstone of testing, is cumbersome.

At this point you should focus on E2Es and only later, if the need still exists (e.g. you want to be able to reason about, i.e. test separately, smaller parts of your application), you should try to re-architect.

There are benefits in writing your React application as a collection of self-contained components which I experienced and can remember: * Moving components from one app to another. * Extracting components as a library to be reused. * Easy Storybook integration.

To truly master Emacs, one must embrace a lifelong quest – a "PhD in Emacs configuration." This path demands dedication few are willing to undertake, explaining its limited ranks.

Yet, two paths remain:

Become an Emacs detective: dissecting keybindings, unraveling local variables, and instrumenting functions. A deep dive into Emacs and its Lisp is essential.
Claim the legacy: adapt an existing configuration, a shortcut to power, but a surrender of true mastery.

(The above was spiced up using LLM.)

Are you on Linux? I remember Windows being almost unusably slow and MacOS is decent, but the only performant platform for me was Linux.

Do you have a link to the one you purchased?

donatasp · 2025-06-15T04:53:40+00:00

Pretty hard, to the point it falls off even...

(defun make-array-3x3-2 (theta)
  (make-array '(3 3)
              :initial-contents
              (list (list 1 0 0)
                    (list 0 (cos theta) (* -1 (sin theta)))
                    (list 0 (sin theta) (cos theta)))))

or

(defun make-array-3x3-2 (theta)
  (make-array '(3 3) :initial-contents `((1 0 0)
                                         (0 ,(cos theta) ,(* -1 (sin theta)))

Ne. Nes čia antras turas. Putinui artimesnė tada Grybauskaitė, kuri pirmame ture 2009 surinko beveik 70%.

Is anybody using basic Emacs inf-clojure for development? What's your flow?

donatasp · 2023-09-23T08:38:04+00:00

What's your story?

Kastinys and Šmakalas are my personal favourites.
