Mixing programming languages for fun and profit

I’ve been looking for a simple HTML5-ish way to represent our disk drives in our Unison units. I’ve been looking for some simple drawing libraries in javascript to make this higher level, so I don’t have to handle all the low level HTML5 bits.
I played with Raphael and a few others (including paper.js). I wound up implementing something in Raphael.

The code that generated this was a little unwieldly … as javascript doesn’t quite have all the constructs one might expect from a modern language. And thanks to its object orientation, its … er … somewhat more verbose than it really needs to be.

Note that there are some constructs there not in javascript. They are the < % $variable %> bits. This is what we use to pass data from the perl template code (Mojolicious and HTML::Mason) into the HTML (and Javascript).
I guess I am finding it humorous that I am having Perl rewrite the Javascript as it emits it. This is minor, variable substitution, but I’ve done more major bits of editing which javascript goes out over the wire.
