# LightScript

*A close superset of ES7 with JSX and Flow, built with Babel. Designed to make programmers a little more productive.*

See [lightscript.org](http://lightscript.org) for example code
and language reference documentation. A quick taste:

```coffee
Item({ item, isActive }) =>
  className = if isActive: 'active' else: 'inactive'

<li className={className}>
    {item}
  </li>
```

Come hang out in [the gitter chatroom](https://gitter.im/lightscript/Lobby), where contributors can help you get started and answer any questions.

### Language Features

In addition to all all ES7, JSX, and Flow features:

- (Optional) Significant Indentation
- Implicit Returns
- If Expressions
- Auto const
- Async/Await shorthand
- Safe-Await
- Readable Operators (or, and, ==, etc)
- Bound Methods
- Commaless Objects and Arrays
- Automatic Semicolon Insertion that always works
- Array Comprehensions
- Object Comprehensions
- Array-based for-loops
- Object-based for-loops
- a few others

Reference documentation is available at [lightscript.org](http://lightscript.org),
or in Markdown format [here](https://github.com/lightscript/lightscript.org/blob/master/pages/docs/docs.md). Tests for all features can be seen
[here](https://github.com/lightscript/babylon-lightscript/tree/lightscript/test/fixtures/lightscript)
and [here](https://github.com/lightscript/babel-plugin-lightscript/tree/master/test/fixtures).

### Project Structure

"LightScript" is split across multiple repos:

- **The Parser**: [babylon-lightscript](https://github.com/lightscript/babylon-lightscript)
  - The core of most of the language.
- **The Babel Plugin**: [babel-plugin-lightscript](https://github.com/lightscript/babel-plugin-lightscript)
  - Rewrites a "LightScript AST" into a "JavaScript AST".
  - The core of what you need to use LightScript.
- **The Babel Preset**: [babel-preset-lightscript](https://github.com/lightscript/babel-preset-lightscript)
  - Provides the rest of ES7 for ES6 environments, as well as runtime typechecking.
- **The Sublime Text Package**: [lightscript-sublime](https://github.com/lightscript/lightscript-sublime)
  - Provides syntax highlighting, albeit somewhat hackily.
  - Available now [on Package Control](https://packagecontrol.io/packages/LightScript).
- **The Atom Package**: [lightscript-atom](https://github.com/lightscript/lightscript-atom)
  - Based on the Sublime Package.
  - Available now on [`apm`](https://atom.io/packages/lightscript-atom).
- **The Visual Studio Code Package**: [lightscript-vscode](https://github.com/lightscript/lightscript-vscode)
  - Based on the Sublime Package.
  - Available now on the [VS Code Extension Marketplace](https://marketplace.visualstudio.com/items?itemName=lightscript.lsc).
- **The Website**: [lightscript.org](https://github.com/lightscript/lightscript.org)
  - In addition to powering lightscript.org, it's also an example of LightScript code in use.

For now, the issue tracker on this repo should be used for bug reports and feature requests.
