# Purple Language Documentation

The standard language specification and compiler for Purple, a general-purpose, C-like language intended to introduce higher-level functionality and lower-level memory access.

[Original Implementation](https://github.com/CharlesAverill/purple_archive/)

## Installation

View the source here.

### Dependencies

- `clang-{10+}`

- `libclang-{10+}-dev`

Purple may be built with cmake:

```bash

cmake -B build

cmake --build build

bin/purple example_file.prp

```

## Grammar

BNF-formatted grammar for Purple can be found here: [Purple Grammar Documentation](purple.g)

## Examples

Purple uses C-style syntax, although this may change as the compiler is built

```c

void main(void) {

    int bob;

    int alice;

    bob = 5;

    alice = 10;

    print bob + alice; // 15

    print bob > alice; // 0

    int bob_alice;

    bob_alice = 10 + 10 + bob + alice; // 35

    if(bob_alice > 30){

        print bob_alice;

    }

    int i;

    i = 0;

    while (i < 20) {

        print i;

        i = i + 1;

    } else {

        print i == 0 or true; // true

    }

}

```
