What do people build with it?

USE CASE 1

Learn how parsers work by defining grammar rules and testing them against sample input.

USE CASE 2

Prototype a domain-specific language for a particular problem before building it for real.

USE CASE 3

Design and test a custom configuration file format's syntax rules.

USE CASE 4

Experiment with ANTLR-generated Swift parsing code in a low-stakes playground.
