# PolyTT 🦜



  



A type theory with native support for [Polynomial Functors](https://topos.site/poly-book.pdf).

For examples, see `std-lib/Tutorial.poly`.

# Building

Install `opam` using our preferred package manager. On Mac you can install it with `homebrew` via:

```bash

$ brew install opam

```

Once you have `opam` you can install all the dev dependencies and then build `polytt`:

```bash

$ opam init

$ opam switch create . ocaml-base-compiler.5.0.0

$ opam install --deps-only --locked .

$ dune build

```

Alternatively, `flake.nix` file is provided to setup an entire development environment with `nix`:

```

$ nix develop

```

# Running

```bash

$ dune exec polytt std-lib/Tutorial.poly

```
