description	Lisp/Scheme core syntax for prompt DSL and meta-programming. Use when writing Lisp-style prompts, defining DSLs, or understanding prompt structure. Trigger phrases: "Lisp语法", "Scheme", "括号语法", "元编程"

Lisp Core Syntax

Overview

Lisp (Scheme dialect) syntax for defining prompt structures and DSLs. Uses parentheses, prefix notation, symbols, lists.

Core Syntax

1. Parentheses

• (function arg1 arg2) - first element is function/operator, rest are arguments

2. Prefix Notation

• (+ 1 2) not 1 + 2

3. Symbols

• Variables, function names: define, let, invoke

4. Lists

• Core data structure, code and data: (1 2 3)

5. Quote

• ' prevents evaluation: '(1 2 3) is data not code

6. let

• Local variables: (let ((x 1) (y 2)) (+ x y))

7. define

• Define variable or function: (define (add x y) (+ x y))

8. Conditionals

• if, cond: (if (> x 0) 'positive 'negative)

9. Lambda

• Anonymous functions: (lambda (x) (+ x 1))

Key Features

• Homoiconicity: Code and data same structure, enables meta-programming
• Dynamic typing
• Macros: Extend language, create new syntax
• Comments: ;; for single line

Usage in Prompts

Lisp syntax used for structured prompt definitions: (define story-prompt '(...)), (let ((context "...")) ...), keyword args :mood "...", nested lists for sequences.

Usage Example

User input: "这段Lisp风格的提示词是什么意思？" AI action: Parses parentheses, explains define/let/lambda, translates to plain language Expected result: Clear explanation of Lisp-style prompt structure
