When to use Interpreter Design Pattern
- When dealing with domain-specific languages:
- If you need to interpret and execute expressions or commands in a domain-specific language (DSL), the Interpreter pattern can provide a flexible and extensible way to implement the language’s grammar and semantics.
- When you have a grammar to interpret:
- If you have a well-defined grammar for expressions or commands that need to be interpreted, the Interpreter pattern can help parse and evaluate these structures efficiently.
- When adding new operations is frequent:
- If your application frequently requires the addition of new operations or commands, the Interpreter pattern allows you to add new expression classes easily without modifying existing code, thus promoting maintainability and extensibility.
- When you want to avoid complex grammar parsers:
- If building and maintaining complex grammar parsers seems daunting or unnecessary for your use case, the Interpreter pattern offers a simpler alternative for interpreting expressions directly.
