An off the top of my head idea for a high level opal framework to write web apps in. The idea is that at the level of application development, you want to stick at the level, i.e. what you see, and what it does. They way it is now, is you have to constantly do deep rabbit hole dives into markup, css, front end vs backend languages etc. The simpl…
require 'opal-tk'
app = App.new
app.main { |main|
main.vbox { |vbox|# vertical box container, auto lays out things vertically
vbox.hbox { |hbox|
hbox.header("Welcome to Opal-Tk").pack # pack means tell my parent to manage me
hbox.separator.pack

Rubyfying Javascript: Avoiding jQuery Spaghetti
