This folder contains various examples ranging from simple Hello World language to a full language for Psychological experiments (pyFlies).

To run these examples clone this repository (or download archive and unpack). Each folder contains README file which describes language and gives instruction how to check/visualize meta-models and models.

Example language are:

• hello_world - a very simple language used for the hello world tutorial.
• robot - A simple DSL for moving robot on an imaginary grid. This example shows how to do model interpretation. Used for the robot tutorial.
• drawing - A simple DSL for drawing. It uses interpretation Similarly to the robot DSL.
• Entity - A simple DSL for modeling data. This example shows how to generate source code from the model. Used for the Entity tutorial.
• expression - Two simple expression languages with variable assignment and expression evaluation. calc.py - four basic arithmetic operations. bool.py - three basic boolean operations.
• workflow - A simple DSL for workflow descriptions.
• json - An example of using textX for parsing data-interchange formats.
• StateMachine - State machine language and example from Fowler's DSL book. An example of source code generator - generating dot file, and an example of state machine interpreter.
• pyFlies - An example of real DSL for the description of cognitive reaction-time experiments. See the pyFlies project.
• IBM_Rhapsody - An example of loading of a model made using IBM Rational Rhapsody.
