Writing a compiler for a DSL in python

Question

I am writing a game in python and have decided to create a DSL for the map data files. I know I could write my own parser with regex, but I am wondering if there are existing py

Answer 1

Here's an approach that works really well.

abc= ONETHING( ... )
xyz= ANOTHERTHING( ... )
pqr= SOMETHING( this=abc, that=123, more=(xyz,123) )

Declarative. Easy-to-parse.

And...

It's actually Python. A few class declarations and the work is done. The DSL is actually class declarations.

What's important is that a DSL merely creates objects. When you define a DSL, first you have to start with an object model. Later, you put some syntax around that object model. You don't start with syntax, you start with the model.
