# Scrapscript Interpreter

See [scrapscript.org](https://scrapscript.org/) for some more information. Keep

in mind that the syntax on the website will change a little bit in the coming

weeks to match this repository.

Take a look inside [scrapscript.py](scrapscript.py) and all of its tests to get

an idea for how the language works.

## Usage

We support python3.8+.

```bash

# With a file

python3 scrapscript.py eval examples/0_home/factorial.scrap

# With a string literal

python3 scrapscript.py apply "1 + 2"

# With a REPL

python3 scrapscript.py repl

```

or with [Cosmopolitan](https://justine.lol/cosmopolitan/index.html):

```bash

./build-com

# With a file

./scrapscript.com eval examples/0_home/factorial.scrap

# With a string literal

./scrapscript.com apply "1 + 2"

# With a REPL

./scrapscript.com repl

```

(if you have an exec format error and use Zsh, either upgrade Zsh or prefix

with `sh`)

or with Docker:

```bash

# With a file (mount your local directory)

docker run --mount type=bind,source="$(pwd)",target=/mnt -i -t ghcr.io/tekknolagi/scrapscript:trunk eval /mnt/examples/0_home/factorial.scrap

# With a string literal

docker run -i -t ghcr.io/tekknolagi/scrapscript:trunk apply "1 + 2"

# With a REPL

docker run -i -t ghcr.io/tekknolagi/scrapscript:trunk repl

```

### The experimental compiler:

#### Normal ELF

```bash

./scrapscript.py compile some.scrap  # produces output.c

./scrapscript.py compile some.scrap --compile  # produces a.out

```

#### Cosmopolitan

```bash

CC=~/Downloads/cosmos/bin/cosmocc ./scrapscript.py compile some.scrap  --compile # produces a.out

```

#### Wasm

```bash

CC=/opt/wasi-sdk/bin/clang \

CFLAGS=-D_WASI_EMULATED_MMAN \

LDFLAGS=-lwasi-emulated-mman \

./scrapscript.py compile some.scrap --compile  # produces a.out

```

## Running Tests

```bash

python3 scrapscript.py test

```
