Welcome to Passerine!
Passerine is a small, concise, extensible programming language, powered by a VM written in Rust.
It was inspired by Scheme, OCaml, Rust, and Wren.
Here's a small taste:
```
-- defining a macro
syntax 'for 'each var 'in list do {
body = var -> do
loop = remaining -> {
match remaining {
() -> (),
[head & tail] -> { body head; remaining tail }
}
}
loop list
}
-- using said macro
for each number in (reverse [1, 2, 3]) {
print (number + "...")
}
print "Liftoff!"
```
## Getting Started
If you just want to see what Passerine can do:
> NOTE: Passerine is in an early stage of development.
It's just barely reached the stage of theoretically being Turing-complete,
but don't @ me yet.
1. Clone this git repository.
2. Build Passerine with cargo.
3. Run the tests.
If you'd like to contribute:
1. Get Passerine.
2. Start developing.
`CONTRIBUTING.md` has general guidelines and discusses project structure
