A programming language and environment for teaching OOP.

## Xtext-based implementation notes

This is the main repository for the Wollok Xtext-based implementation, which is part of the [Wollok Language Specification](https://github.com/uqbar-project/wollok-language)

## Installation ##

You have two options to download an use Wollok.
**Download a complete Wollok Product Distribution**:

* Linux [64](http://download.uqbar.org/wollok/products/stable/wollok-linux.gtk.x86_64.zip) bits
* Mac [64](http://download.uqbar.org/wollok/products/stable/wollok-macosx.cocoa.x86_64.zip) bits
* Windows [64](http://download.uqbar.org/wollok/products/stable/wollok-win32.win32.x86_64.zip) bits

**Update Site (if you already have a compatible eclipse)**:
* http://update.uqbar.org/wollok/stable : for the latest stable release
* http://update.uqbar.org/wollok/dev : for the current dev (work in progress) version

## Wollok SDK standalone ##

Finally if you just want the headless Development Kit (WDK), for example to use a different IDE than Eclipse, you can download it from

- https://github.com/uqbar-project/wollok-cli

This is useful for example if you are going to develop with [Sublime](https://github.com/uqbar-project/wollok-sublime-linter/blob/master/README.md) or any other lightweight text editor

## Documentation ##

Refer to the [wiki](https://github.com/uqbar-project/wollok/wiki/Home) for documentation like [Language Reference](https://www.wollok.org/en/documentation/wollokdoc/) and Environment.

## What's the language like ? ##

* **Object Oriented**
* Non "class-centered". Allows you to create **objects as first-class citizens without the need of classes**. To start working with objects without introducing complex subjects and mechanisms as hierarchies, overriding methods, etc.
* Tries to **maximize compile-time checks** while keeping the **power of a dynamic language.**
* With **implicit types**: by means of a type system and type inference mechanism.
* A **clean modern syntax** avoiding unnecessary symbols (java) while keeping it simple and even familiar for those who already have some experience in programming)
* **Interpreted**: means that the code is being evaluated as it's being read. Although its **declarative syntax** makes it feel like a compiled language

```wollok
package fliers {

object superman {
        method fly(to) {
             // ...
        }
   }

class Plane {
        method fly(to) {
            // ...
        }
   }

}

val aBird = object {
        method fly(to) {
             // ...
        }
  }

[ superman, new Plane(), aBird ].forEach { o => o.fly() }
```

Check out our [Language Reference](https://www.wollok.org/en/documentation/concepts/) for a concrete idea of the syntax

## How is the Environment ? ##

You can either use its IDE:
* Completely **integrated with Eclipse**.
* With: many **static code analysis**, **Quick-Fixes**, **Refactors**
* An **interactive Console** (**REPL**)
* **Visual representations**: Outline, Static diagram, Objects Diagrams

Or use the wollok-cli which has command line tools for running and checkin a program.
