Domain Specific Languages #3 | From Syntax to Structure: Generating Data Models

Sat, 11 Oct 2025 00:00:00 +0000

Intro & Quick Recap

In the previous posts:

Part #1 | Introduction → We defined the problem.
Part #2 | Rapid DSL Design → We designed a minimal DSL syntax.

Now that we have a working syntax, it’s time to represent it in code.

Why Data Structures Matter

The DSL syntax is just text — it needs structure before it becomes useful. That’s where data models come in. They serve as the backbone of the language, bridging the gap between the written syntax and the C# code we’ll eventually generate.

The Minimal Type Syntax: Core Concepts

We will design a minimal and clean type syntax heavily influenced by GoLang ¹.

Let’s split the text into TOKENS. A token is a group of characters. The lexer first reads and groups the character stream into semi-meaningful groups. Then the parser uses these to generate a syntax tree.

I don’t want to speak too soon, but I’ve addressed a similar issue in .NET and started developing a simple DSL to tackle it. Currently, it offers the bare minimum for C# code generation with basic MSBuild integration.

The development is private for now, and the project is named Typr. (I considered Type-R as well, but opted for the shorter name.)
