# Shem

Shem is a new compiled-to-JS, statically typed, pure-by-default functional programming language. The semantics are based on [Haskell](https://www.haskell.org/) but the language evaluates strictly in a similar way to [PureScript](http://purescript.org/). The syntax is S-expressions-based, allowing for a full-blown LISP-like macro system. Shem's prelude includes a full-featured, highly-polymorphic collections library backed by [ImmutableJS](http://facebook.github.io/immutable-js).

The language has been designed for the use within its custom built IDE, [Golem](https://github.com/xixixao/Golem) available at [http://xixixao.github.io/Golem](http://xixixao.github.io/Golem), inspired by [Bret Victor](http://worrydream.com/).

## Use without Golem

Clone this repo, go to the folder, then

```bash

npm install

npm run build

```

To run a single file

echo '_ (.log (global "console") "Hello world!")' > test.shem

bin/shem test.shem

```

To compile a single file to JavaScript

```

bin/shem -c test.shem

```

To run a module

```bash

mkdir test-modules

echo 'message "Hello, hello, world!"' > test-modules/Hello.shem

echo '[message] (req ./Hello) _ (.log (global "console") message)' > test-modules/index.shem

bin/shem test-modules

```

To compile a module

```bash
