# Eye

**🚧 Work in progress 🚧**

Eye is a statically typed compiled language implemented using LLVM, with a syntax inspired by TypeScript.

```typescript

interface Counter {

  inc: () => i64,

  reset: () => void

}

function makeCounter(initialValue: i64): Counter {

  let counter = initialValue;

  let inc = (): i64 => {

    counter = counter + 1;

    return counter;

  };

  let reset = (): void => {

    counter = 0;

  };

  return { inc: inc, reset: reset };

}

function main(): i64 {

  let counter = makeCounter(10);

  let inc = counter.inc;

  let reset = counter.reset;

  print(inc());

  print(inc());

  reset();

  print(inc());

  print(inc());

  return 0;

}

```

Roadmap is available in [`TODO.md`](TODO.md).

## Build

```bash

make all

```

Make sure you have LLVM installed.

On macOS 13, I have LLVM installed through [Brew](https://formulae.brew.sh/formula/llvm), with following environment variables set:

```bash

export PATH="/opt/homebrew/opt/llvm/bin:$PATH"

export SDKROOT="$(xcrun --show-sdk-path)"

export LIBRARY_PATH="$LIBRARY_PATH:$SDKROOT/usr/lib"

export LDFLAGS="-L/opt/homebrew/opt/llvm/lib"

export CPPFLAGS="-I/opt/homebrew/opt/llvm/include"

```

## Run example programs

```bash

# compile and run

make program SOURCE_FILE=snapshots/closure.eye && ./program

# compile and run (debug)

DEBUG=1 make program SOURCE_FILE=snapshots/closure.eye && ./program

```

## Tests

Testing is done by checking the expected change in snapshots.

```bash

make snapshot

```

## Name

The name "Eye" is inspired by the [IJ bay in Amsterdam](https://en.wikipedia.org/wiki/IJ_(Amsterdam)).
