This is an 🚧 extremely alpha-stage 🚧 piece of software. It works for certain narrow use cases the authors have, and might be interesting to you, but it's very likely to explode in your face, or return a clown instead of an integer.

For the impatient - this package uses Stack. You'll probably want to brew install haskell-stack.

$ stack install alex happy
$ make
# you can also run tests:
$ make test

We had a desire to write a ray tracer in Visual Basic 6, the easiest way to create a retro GUI. The thing is, performance was awful. So we did some benchmarks and thought we could probably reshuffle our code. It was very function-call-heavy of course, and in VB that's pretty slow. Unfortunately it turned out to be quite a rabbit hole, and so we first had to write a parser, then a pretty printer, then a bunch of optimisation phases, all of which were a bit more involved than we'd hoped.
