It'd be great if there was a good way to point out what's useful about each example. This could be done, perhaps with a div on the left-hand side, giving suggestions on what to do to play with the example.

An example might be: "Try clicking on 'fib' and move the slider to a different color."

Right now, a lot of things don't get interpreted. More of the examples should work though!

If you want to help, take a look at src/interp.js.

The type inference is an awesome language feature, but it can be even better than it is right now. I envision type inference as the default way of code getting colored, and allowing users to customize from there. That means:

1. Type inference should detect more things
2. Users should usually be able to override the automatic type inference where it makes sense (allow an integer to receive a float value, that would presumably just be cast to an int).

I'd also really like to see type inference involving object properties, i.e.

var foo = {bar: true, baz: 7};
var shouldBeBool = foo.bar;
var shouldBeInt = foo.baz;

If you want to help out, check out src/inference.js for the current type inference code.

It'd be cool if the travis badge had a rainbow background. Feel free to submit a PR!

If you click on the fibonacci example (lets say, on the last line), the cursor won't be adjusted quite right. It'll look as if it's partially between lines 14 and 15 (mostly on 15, where it should be). Once you start typing, everything works looks correct once again.

This has to do with adding in the underlines, which increase the height of the lines. This is something that ideally should get fixed, since it's annoying for examples with lots of underlines.

Or, we can investigate different styles, like tinting the background with a lighter shade of a lighter color, instead of underlining.

Type inferencer (bin/rain-infer.js)

• should accept a rain file as stdin
• should optionally output a type dictionary to stdout
  • (maybe) optionally pretty-print JSON
• should do something useful if there's no existing raint type dictionary

Interpreter (bin/rain-interp.js)

• should do something useful if there's no existing raint type dictionary

Codemirror lets you use linewidgets to display error messages beneath a specific line. I'd probably be most interested in something along the lines seen for CDG's prolog visualizer.
