SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

DomainLang teams often struggle to decide on the best syntax, semantics, and grammar for new language features, leading to inconsistent proposals and slower progress.

Core Features & Use Cases

  • Structured guidance for evaluating language design options, including syntax decisions, semantic definitions, and alignment with DDD patterns.
  • Trade-off analysis templates to compare readability, writability, expressiveness, and maintainability.
  • Design rationale templates and documentation guidance to capture decisions for future contributors.

Quick Start

When faced with a proposed feature, provide a concise critique that outlines the problem, presents at least two alternative designs, and documents recommended trade-offs.

FAQPage Schema
How do I evaluate syntax alternatives for a new DSL feature?

To evaluate syntax alternatives for a new DSL feature, apply structured guidance that presents at least two design options and documents trade-offs between readability, writability, and maintainability.

What is the best way to document design rationale for DDD patterns?

Documenting design rationale for DDD patterns requires using specific templates to capture decisions, enforce precise semantic definitions, and record trade-off analyses to guide future contributors.

How do I perform a trade-off analysis between readability and expressiveness in language design?

Performing a trade-off analysis between readability and expressiveness uses provided templates to compare alternative syntax proposals systematically, ensuring design decisions are justified and documented for maintainability.

When do I need precise semantics definitions for domain-specific languages?

Precise semantics definitions for domain-specific languages are needed when proposing new language features, evaluating grammar updates, or aligning syntax decisions with underlying DDD patterns to ensure consistency.

Does this approach work for evaluating grammar proposals without existing dependencies?

Yes, evaluating grammar proposals works without external dependencies by applying structured critique templates to analyze syntax alternatives, define semantics, and justify design trade-offs independently.
