Operational Semantics Builder

Purpose

Provides expert guidance on defining operational semantics for programming language specification and testing.

Capabilities

  • Small-step semantics rule generation
  • Big-step semantics rule generation
  • Evaluation context definition
  • Substitution and binding handling
  • Semantics execution/testing
  • Equivalence proofs

Usage Guidelines

  1. Semantics Style: Choose small-step or big-step
  2. Rule Definition: Define reduction/evaluation rules
  3. Contexts: Define evaluation contexts if needed
  4. Testing: Execute semantics on test programs
  5. Validation: Verify expected behavior
