Mandelbrot Renderer Script in Jn

The truth about Svelte

I've been deceiving you all. I had you believe that Svelte was a UI framework — unlike React and Vue etc, because it shifts work out of the client and into the compiler, but a framework nonetheless.

But that's not exactly accurate. In my defense, I didn't realise it myself until very recently. But with Svelte 3 around the corner, it's time to come clean about what Svelte really is.

Svelte is a language.

Specifically, Svelte is an attempt to answer a question that many people have asked, and a few have answered: what would it look like if we had a language for describing reactive user interfaces?

A few projects that have answered this question:

Annotated LightTable Theme
/* LightTable themes are just CSS. LightTable, CodeMirror, and plugins apply
classes to tokens within the text. Most of these classes are undocumented. I
had to go fishing with the dev inspector and apply brightly colored rules to
figure it out. Hopefully I can save you the trouble by documenting the default
theme. Please comment if you find any errors or omissions. */
/* These #multi rules apply to tabsets. Active means currently selected and dirty
means that the file has been edited since the last save. */

A little utility to allow simple redeployment of Clojure web servers with zero downtime, and without the need for a proxy or load balancer. Just wrap any port-binding calls, and the utility will auto kill pre-existing servers as necessary. *nix only. Based on the blog post by Feng Shen, http://shenfeng.me/fast-restart-clojure-webapp.html
;; (require '[clojure.string :as str] '[clojure.java.shell :as shell] '[taoensso.timbre :as timbre])
(defn with-free-port!
"Attempts to kill any current port-binding process, then repeatedly executes
nullary `bind-port!-fn` (which must return logical true on successful
binding). Returns the function's result when successful, else throws an
exception. *nix only.
This idea courtesy of Feng Shen, Ref. http://goo.gl/kEolu."
