Raspberry Pi test code for James
''' Jeremy's test script - 28 Mar 2020.
It creates two threads and waits for both to finish before presenting the results.
Each thread generates random data, but data that is similar to what is expected from the sensor devices.
The results are added to the queue, removed, then presented to the user.
Not completed: writing to '''

React Native + macOS + Clojurescript

Project Catalyst

Since the recent release of Catalina, macOS has shipped with the ability to allow iOS/iPAD apps to run on macOS without any modification via a featureset known as Project Catalyst.

This is exciting, as writing React Native + Clojurescript apps as a target for the desktop is much more compelling than a pure Electron app (imo).

Using JavaScript modules in ClojureScript

Using JavaScript Libraries from ClojureScript

Using JavaScript libraries from ClojureScript involves two distinct concerns:

  1. Packaging the code and delivering it to the browser
  2. Making ClojureScript code that accesses JavaScript libraries safe for advanced optimization

Right now, the only single tool that solves these probems reliably, optimally, and with minimal configuration is shadow-cljs, and so that is what I favor. In paricular, shadow-cljs lets you install npm modules using npm or yarn and uses the resulting package.json to bundle external dependencies. Below I describe why, what alternatives there are, and what solutions I disfavor at this time.

Packaging and Delivering Code

Clojure's `eval` and namespaces
;; Clojure's eval is dynamic with respect to current namespace.
;; If you ever find yourself in need of eval but want to avoid **wat**
