# C2
C2 is a programming language based on C.
It adds modern high-level features such as metaprogramming, generics, etc,
but compiles down to C89.

## Building
To build the c2–compiler, simply run `make` or `make all`.
This will build the compiler and run the tests.

In order to only build the compiler, run `make c2`.
In order to run the tests, run `make test`.

## Versioning
The current version is v0. Its source code lives in the `v0` directory.

## Testing

### Unit Tests
Run unit tests with:
```bash
make test
```

### Integration Tests
Integration tests compare the compiler output with expected C files.
To add a new integration test, create a new directory under `v0/integration_tests/` with `input.c2` and `expected.c` files.
Run integration tests with:
```bash
make integration-test
```
