A simplistic terminal emulator HTML component
This component was designed to accompany the book Learn ClojureScript as a way to teach simple concepts such as control structures without requiring the reader to already know about DOM manipulation, event handling, etc.
(ns myapp
(:require [bterm.core :as bterm]
[bterm.io :as io]))
;; Attach component to the DOM
(def terminal (bterm/attach (.getElementById js/document "terminal")
{:font-size 14
:prompt "$ "}))
;; Print text to the terminal
(io/println terminal "Hello there, fine person. What do you say?")
;; Handle input
(io/read terminal
(fn [input]
(io/println terminal "Thank you for saying, \"%s\"" input)))
To get an interactive development environment run:
lein figwheel
and open your browser at localhost:3449. This will auto compile and send all changes to the browser without the need to reload. After the compilation process is complete, you will get a Browser Connected REPL. An easy way to try it is:
(js/alert "Am I connected?")
and you should see an alert in the browser window.
To clean all compiled files:
lein clean
To create a production build run:
lein do clean, cljsbuild once min
And open your browser in resources/public/index.html. You will not
get live reloading, nor a REPL.
