This project was for a class in which we submitted java. I wrote this Clojure code to produce a Java class that could be run according to their specifications. So here is some of the first Clojure I ever wrote, long ago in grad school, utilizing the OpenCV system for computer vision. Notice the heavy use of obscure (non-Clojurey) APIs on objexts, marked by all the (.XYZ ...) lines. (ns com.

Previously I’ve talked about the inability to refer to my code screens from within exwm if I’m on a video call in my browser; it shows the option fo other browser windows, and the option of the whole screen, but not an emacs buffer. The solution is simple and beautifully recursive: run emacs within your exwm emacs. Do what? Run emacs within your main exwm emacs session. M-S & emacs.

Using exwm with emacs-in-emacs I sometimes make a mistake and start a shell-process going that I need to stop. However, C-c is grabbed by my parent exwm session and so doesn’t send anything to my shell. How can I do this manually? Answer C-c C-c is short for comint-interrupt-subjob Resources https://www.reddit.com/r/emacs/comments/ja97xs/weekly_tipstricketc_thread/g8xu647?utm_source=share&utm_medium=web2x&context=3

The need: take multiple vectors and view each vector as a column (not a row) of the data, so all the first items go together, all the second, etc. Here’s a rough version that felt too clunky (alert: it features a number) and fragile but happens to demonstrate the needs: (let [[names jobs langs :as all] [["john" "jane" "michael"] ["chef" "driver" "vet"] ["English" "German" "French"]]] (map #(zipmap [:name :job :lang] %) (partition 3 (interleave names jobs langs)))) ;; ({:name "john", :job "chef", :lang "English"} ;; {:name "jane", :job "driver", :lang "German"} ;; {:name "michael", :job "vet", :lang "French"}) Solution (let [[names jobs langs :as all] [["john" "jane" "michael"] ["chef" "driver" "vet"] ["English" "German" "French"]]] (apply map #(zipmap [:name :job :lang] %&) all)) ;; => ({:name "john", :job "chef", :lang "English"} {:name "jane", :job "driver", :lang "German"} {:name "michael", :job "vet", :lang "French"}) This solution taught me two new things:

I find myself going back to regular WMs (my favorite from the past being KDE) because certain tasks are just deeply punishing in EXWM. When I’m doing my regular daily work I can usually make EXWM work for me. But here are the facts I experience with/without emacs as my window manager. Life is worse without EXWM Winum. Looking at a screen and hitting the num to focus there; I miss it dearly and cringe when I need to reach for the mouse.

I use exwm so M-TAB is available to me without being hijacked by the OS, but rebinding this failed in surprising places. I want it globally to be set to iflipb-next-buffer (giving familiar alt+tab functionality to exwm), but if any of the buffers I’m travelling past happen to inherit magit or gnus, my tab-sequence gets broken because they have it bound to their own thing and I can’t seem to rebind it.

By default ivy/swiper/counsel (not sure which) will visit all results as I scan through a list, e.g. when going through my buffers. I thought I liked this until working on my exwm with multiple monitors and non-emacs buffers are only allowed to appear once, meaning that simply moving down my selection list caused screen to be stolen from my other monitor. Answer Buffer-changes are apparently an effect of using counsel-switch-buffer, which I had bound to C-x b.

After years of a languishing example of The Cobbler’s Children , I finally got around to renovating my own website: toryanderson.com. Admittedly I have a lot to learn about visual design, but I had a good time on the technical front. I took the opportunity to use technologies I love and have been pleased with the result – both in the product and the cost constraints. In other words, it was fun to build and cheap to host: Clojure[script] meets shared hosting.

My ordinary workflow was to start emacs with a load into my orgmode agenda, which locates me in my .emacs git-project. Upon inspecting my agenda I’ll go to some project from my todo list using helm-projectile. However, after switching to Staight.el (which does its heavy lifting with git) this workflow was broken. The result is that, when I try to use projectile from somewhere that Git includes Straight stuff, I get this failure about submodules:

Accordions are actually available out-of-the-box in Clojurescript with the included Google closure.js that Clojurescript is built upon. This code shows the AnimatedZippy, which has a nice slide-out function; there’s also a plain Zippy. They are drop-in replacements for eachother. Rendering the Accordion (Zippy) (ns toryanderson.views.components.shared "Shared components that may be used on multiple views" (:require [reagent.core :as r] [goog.dom :as dom] [goog.string :as gstr]) (:import goog.ui.AnimatedZippy)) (defn accordion [{:keys [header-text content-body]}] (let [header-id (gstr/createUniqueString) content-id (gstr/createUniqueString)] (r/create-class {:display-name "zippy" :reagent-render (fn [id] [:div.
