name: cairo-macros description: Explain Cairo declarative macros, macro hygiene, and macro vs function tradeoffs; use when a request involves writing or understanding macro definitions in Cairo.

Cairo Macros

Overview

Explain declarative (inline) macros, pattern matching, and hygiene in Cairo.

Quick Use

• Read references/macros.md before answering.
• Show a small macro definition with pattern and expansion.
• Mention $defsite, $callsite, and expose! when hygiene matters.

Response Checklist

• Explain that macros expand at compile time and can take variable arguments.
• Note that macros must be defined or imported before use.
• Use match-like patterns with $() and repetition modifiers.

Example Requests

• "How do I write an array-building macro?"
• "What are $defsite and $callsite in Cairo macros?"
• "When should I use a macro instead of a function?"
