 DSL Forge is a framework for the development of domain-specific language (DSL) editors for web applications and cloud IDEs. 
 It allows to get web-based textual editors automatically from ANTLR grammars. From the language grammar specification, JavaScript parser and lexer are automatically generated and embedded into Cloud9’s ACE editor.

 # Use Cases
 Below some examples of use cases showing how the generated editors can be integrated with Web IDEs, forms, HTML5 canvas, guiders, and many other popular JavaScript frameworks.
 
- - The following use case is a petrinet form made up of an embedded textual editor integrated with [D3.js](https://d3js.org/) framework. The form is available in the  [live demo](http://beeone.dslforge.org/workbench), open the petrinet project folder, right click on a petrinet model file, and select "Open with form editor".

- - The following use case is an online coding game made with DSL Forge. It comes with a domain-specific language for specifying the actions of a robot, a remote debugger, next to a canvas animation made with [Phaser.js](https://phaser.io/). The game is free and publicly available on [CodingPark](http://www.codingpark.org).
