Oh Yeah: Irb Applet #

by why in inspect

You’re going to ask yourself, “What’s the point?” And, sure, go ahead. Take a minute. But, wow. What’s key: This doesn’t hit the server.

I wonder if we can put the Try Ruby face on it and pass commands in and out. No doubt, I’m sure. (From Headius.)

Update: If you want to give the applet access to your filesystem so you can use it for reals, here’s a ~/.java.policy file for you. You’ll need to restart your browser.

grant codeBase "http://www.headius.com/-" {
  permission java.io.FilePermission "<>", "write, read";
  permission java.util.PropertyPermission "*", "read, write";

Geez, is the JVM ever going to not take a minute to boot up?

I was expecting attempted file access to cause a pop-up asking for permission like other applets do. Is it possible to do it that way on demand at runtime?

why: I’d love to make it prettier with a TryRuby-style interface and more robust applet code. Other ideas: an even slimmer applet/plugin that allows ruby scripting of the DOM ; client-server apps with browser clients all in Ruby. Also, since this is a complete Ruby interpreter in a JAR file, you can provide a working interpreter that works on all platforms without modification. Lots of cool stuff.

Danno: I think the real slowdown is downloading the applet and starting up JRuby. The applet is almost 2MB and JRuby is still unpleasantly slow to start up. But this is really just proof-of-concept work…alpha quality, but intriguing.

slumos: Probably…I haven’t done applet work in probably 8 years, so this was mostly an experiment to prove it could be done.

love the idea – but is the download size not going to be an issue (some people complain that prototype is too big at 50k :)

Any WPF irb out there?

Damian Steer has an even slicker one : http://kessel.ilrt.bris.ac.uk/~pldms/2006/12/jruby-applet.html

apparently it’s super easy to “require ‘mylib’” – so you should be able to use it to showcase one’s libraries. has Balloon just been popped ?

I wonder how the strings return their Unicode length in there
