Daniel Pope - Writing Domain Specific Languages with Python
[EuroPython 2015]
[24 July 2015]
[Bilbao, Euskadi, Spain]

Python is an expressive general purpose programming language. Its
syntax provides many ways to represent structure and minimise code
repetition and boilerplate.

But Python not always expressible enough. Perhaps when you've built a
complicated enough system with hard-to-express inter-relationships,
the code required to construct or operate on it can become
complicated, repetitive and unreadable. Or perhaps you have users
unfamiliar with Python who need to understand or edit a system. In
cases like these, stepping beyond the syntax and semantics of basic
Python can be an advantage.

Daniel will describe various ways you can implement your own Domain
Specific Languages, languages perhaps completely unlike Python that
can succinctly describe more complicated Python systems.

This talk will cover:

What and why of DSLs
Metaprogramming tricks
Writing simple parsers
The libraries PLY and PyParsing
Building tooling around your new DSLs
