Portcullis
A minimalist / functional / dataflow programming language.
fib.po
compiles to fib.js
```js
// signature: (Num -> Num)
export function fib(n) {
return (
_lte_(n)(1.0) ? 1.0 : _plus_(fib(_minus_(n)(1.0)))(fib(_minus_(n)(2.0)))
);
}
```
compiles to fib.py
```py
# signature: (Num -> Num)
def fib(n):
return (1.0 if _lte_(n)(1.0) else _plus_(fib(_minus_(n)(1.0)))(fib(_minus_(n)(2.0))))
```
compiles to fib.lua
```lua
-- signature: (Num -> Num)
function fib(n)
return (_lte_(n)(1.0) > 0 and 1.0 or _plus_(fib(_minus_(n)(1.0)))(fib(_minus_(n)(2.0))))
end
```

## About
I wrote the compiler for Portcullis purely for my own education and amusement. Painfully specific goals guided the development of this project and account for both the language features I chose to include as well as omit.
Some of these goals include
- minimalism
- [purity](https://en.wikipedia.org/wiki/Purely_functional_programming)
- [parametric polymorphism](https://en.wikipedia.org/wiki/Parametric_polymorphism)
