# monkey-interpreter-rs
Writing an interpreter for Monkey in Rust.
## Introduction
this project is a Rust implementation of [_Writing An Interpreter In Go_](https://interpreterbook.com/).
see the Monkey language [here](https://monkeylang.org/#what-is-monkey).
## Example
there is currently a very simple CLI in [`main.rs`](src/main.rs) that can run with
```shell
cargo run
```
> **Note**
>
> press `` to quit the REPL
then, typing Monkey code should output the resulting AST, e.g.
```c
let f = fn(x, y) { return x + y; }; f(1, 2);
```
will generate the following AST
```js
Program {
statements: [
Let(
"f",
Function(
[ "x", "y" ],
[ Return(Infix(Identifier("x"), Plus, Identifier("y"))) ],
),
),
Expression(
Call(
Identifier("f"),
[ IntegerLitteral(1), IntegerLitteral(2) ],
),
),
],
}
```
## Roadmap

- [x] parser
- [x] _let_ statements
- [x] _return_ statements
- [x] expressions
- [x] extensions
- [x] boolean literals
- [x] grouped expressions
- [x] _if_ expressions
- [x] function literals
- [x] call expressions
- [ ] evaluation
- [ ] extensions
- [ ] strings
- [ ] built-in functions
- [ ] arrays
- [ ] hash maps
- [ ] CLI
