Creating Domain Specific Languages in Python

In this session I'll talk about using domain specific languages (DSL) in Python. DSLs are small languages specific to a particular domain that make it easier to read and write code in that domain. We'll see how you can parse DSLs using the PyParsing library as well as using regular python code to create DSLs.

This session covers parsing and executing DSLs in python. Covered in the talk are:

• What are DSLs and why do we need them?
• Complexity of coding without DSLs
• Creating a small DSL language
• Creating the grammar
• Using PyParsing to parse the DSL
• Performing the actions
• Creating DSLs using regular python code
• Creating classes and operators to map to the problem domain
• Summary
