# SimPL Interpreter

An *interpreter* for the programming language SimPL (pronounced *simple*).

SimPL is a simplified dialect of ML, which can be used for both *functional* and *imperative* programming.

It's a project for the course *Programming Languages* at *Shanghai Jiao Tong University*.

See [the course website](https://www.cs.sjtu.edu.cn/~kzhu/cs383) for more details.

## Features

- ML-like syntax.

- Algorithm W type inference.

- Call-by-value and call-by-need evaluation strategies.

- Infinite data structures.

- GC based on copy collection.

## Get Started

```bash

# Interpret a SimPL program

$ gradle run --args="doc/examples/gc.spl"

# Run tests

$ gradle test

# Build a standalone jar

$ gradle shadowJar

```

The grammar resides in `src/main/cup/simpl/parser/simpl.cup`.

You may find `src/main/java/simpl/interpreter` useful if you'd like to dig into the evaluation process,

and `src/main/java/simpl/typing` if you're interested in type inference.

Please refer to [Specification](doc/spec.pdf) for mandatory project requirements,

and [Report](doc/report.pdf) for implementation details.

## Examples

See `doc/examples` for some SimPL programs.
